Abstract:

Direct tension strength tests were conducted on chemical vapor deposited silicon carbide microspecimens. Three types of specimens were used: straight gage section, tapered gage section, and notched gage section. The average strengths and standards deviations were: 0.42 GPa ± 0.13 GPa; 0.47 GPa ± 0.16 GPa; and 0.68 GPa ± 0.19 GPa, respectively. The fracture origins were identified by fractographic analysis and were cracks in large grains next to surface grooves from the deep reactive ion etch (DRIE) process used to fabricate the specimens.

Abstract:

In this study, the strains of artificial rock were analyzed in order to estimate the deformation behavior of rock-like materials in the SHPB test. The axial strain measured directly from the strain gage and obtained from the process analysis of three-wave method were compared. The analysis results show that: (1) the measurements of dynamic strains of material obtained from the strain gage method are feasible; (2) the axial strains and strain rates analyzed from the strain gage records are less than those obtained from the three-wave method; (3) the dynamic/static deformation modulus ratio Ed/Eshas the increasing tendency with the raising of stress rate, and the modulus ratio obtained from the strain gage method is more than that obtained from the three-wave method.

Abstract:

In this study, the accuracy of blind-hole method on weld residual stress estimation is investigated. A modified parameter group has also proposed to improve the accuracy. The thermal-elastic-plastic finite element model is employed to build up the residual stress distribution and the blind-hole process. The MSC Marc finite element software package is used to simulate the welding process and the welding residual stress and strain distributions around the weld of two inconel 690 alloy plates filled with I-52 GTAW filler. Then the process of the traditional blind hole is simulated by employing the inactive elements. The data of the residual strain variations of strain gages located around the blind hole is introduced into the blind-hole method to estimate the original residual stress components at the hole center. The effects of drilling depth, drilling size, gage radius, gage position, and the distance on the accuracy of estimated residual stress have also been studied and discussed. Based on the residual stress components simulated from the welding process, a modified stress parameter group has also been proposed to improve the accuracy of blind-hole method. Numerical results indicate that the accuracy of estimated residual stress can be improved significantly by employing the proposed blind-hole parameters.

Abstract:

Purpose A process improvement sampling methodology, known as process variation diagnostic tool (PROVADT), was proposed by Cox et al. (2013). The method was designed to support the objectivity of Six Sigma projects performing the measure-analyse phases of the define-measure-analyse-improve-control cycle. An issue in PROVADT is that it is unable to distinguish between measurement and product variation in the presence of a poor Gage repeatability and reproducibility (R&R) result. The purpose of this paper is to improve and address PROVADT’s sampling structure by enabling a true Gage R&R as part of its design. Design/methodology/approach This paper derives an enhanced PROVADT method by examining the theoretical sampling constraints required to perform a Gage R&R study. The original PROVADT method is then extended to fulfil these requirements. To test this enhanced approach, it was applied first to a simulated manufacturing process and then in two industry case studies. Findings The results in this paper demonstrates that enhanced PROVADT was able to achieve a full Gage R&R result. This required 20 additional measurements when compared to the original method, but saved up to ten additional products and 20 additional measurements being taken in future experiments if the original method failed to obtain a valid Gage R&R. These benefits were highlighted in simulation and industry case studies. Originality/value The work into the PROVADT method aims to improve the objectivity of early Six Sigma analyses of quality issues, which has documented issues.

Abstract:

Purpose The purpose of the paper is to improve the control of vapour phase soldering (VPS). To enable better productivity and assembling quality, the industry needs to provide precise control and measurements during assembling. In the paper, a special monitoring method is presented for VPS to enable improved process control and oven state identification. Design/methodology/approach The work presents the investigation of the workspace with dynamic and gage type pressure sensors in fusion with thermocouples. Different sensors were evaluated to find an appropriate type. The relation between the temperature and the pressure was investigated, according to the setup of the oven. The effect of inserting a printed circuit board (PCB) on the pressure of the vapour inside the oven was also investigated with the pressure/power functions. Findings It was found that the novel gage-type sensors enable better precision than solutions seen in previous literature. The sensors are able to monitor the decreasing vapour concentration when a PCB is inserted to the workspace. It was found that there is a suggested minimum power to sustain a well-developed vapour column for soldering in saturated vapour. An inflexion point highlights this in the pressure/power function, in accordance with the temperature/power curve. Originality/value The research presents original works with aspects of a novel sensor fusion concept and work space monitoring for better process control and improved soldering quality.

Abstract:

This paper presents the development of a new dynamic model of the rolling process which provides estimates of the variations in exit gage, strip speed and tension at entry and exit, rolling force and rolling torque in response to variations in roll separation as well as the rate of change of the roll spacing. This two-dimensional dynamic model employs the Tresca friction factor approach instead of Amontons-Coulomb friction law.

Abstract:

This paper describes the design and implementation of a gage for measuring the wall thickness of hot rolled steel tubing at an actual production facility. The design is based upon a statistical analysis of the tube samples, and upon the economic realities of mill operating conditions. Issues relating to time constraints, uneven sample preparation, a mill operating environment, and differences between gage operators are addressed. The gage records more data from the tubes than could be taken manually, and therefore allows the accompanying software to apply unique algorithms for the calculation of hexing and eccentricity in each sample. All results are recorded and stored in a database for continuous use in statistical process control.

Abstract:

Polymer-based additive manufacturing (AM) gathers a great deal of interest with regard to standardization and implementation in mass production. A new methodology for the system and process capabilities analysis in additive manufacturing, using statistical quality tools for production management, is proposed. A large sample of small specimens of circular shape was manufactured of photopolymer resins using polymer jetting (PolyJet) technology. Two critical geometrical features of the specimen were investigated. The variability of the measurement system was determined by Gage repeatability and reproducibility (Gage R&R) methodology. Machine and process capabilities were performed in relation to the defined tolerance limits and the results were analyzed based on the requirements from the statistical process control. The results showed that the EDEN 350 system capability and PolyJet process capability enables obtaining capability indices over 1.67 within the capable tolerance interval of 0.22 mm. Furthermore, PolyJet technology depositing thin layers of resins droplets of 0.016 mm allows for manufacturing in a short time of a high volume of parts for mass production with a tolerance matching the ISO 286 IT9 grade for radial dimension and IT10 grade for linear dimensions on the Z-axis, respectively. Using microscopy analysis some results were explained and validated from the capability study.

Abstract:

Two systems of milking machines were considered - biotechnical and vacuum. Methodology for estimation of efficiency of the "machine-animal" biotechnical system was worked out. The dependences of the efficiency parameters of the technical system operation were analyzed. The KMMO operator load factor of the milking machine was proposed. The factor characterizes the technological process of the machine milking. The analytical dependences were worked out for the simulation of the productivity of milking machines and oscillation of the vacuum-gage pressure. As to the simulation results, when the vacuum pipeline diameter was increased the oscillation of the vacuum-gage pressure decreased. The results of analysis and theoretical researches on technological process of the cow machine milking gave a possibility to define the requirements to the improvement of technological process and technical equipment, which will provide the increase of efficiency of the milking systems. Usage of the developed cyber-physical system of the machine milking of cows will increase the productivity of the milking machine in 1.26…1.85 times. At the vacuum gage pressure oscillation of ΔPvp = 2500 Pa the suction ability of milking machine will be E=4.093 m/s accordingly. The defined index of efficiency of the adapted systems functioning of the milking machine is KBTS2 = 55.3.

Abstract:

Profile waviness is one of the main causes for scrapped parts in precision bore grinding. Although efforts have been made to reduce its occurrence, the problem has not been eliminated completely. In production, the identification of a few scrapped parts in a lot of several thousands often requires expensive manual processes. Grinding machines used to produce these parts are usually equipped with measurement gage heads having tactile probes. Until now, these in-process gages have been used to measure only the average diameter of the part.This research focused on the use of these tactile probes to measure bore waviness in precision-ground parts. The first objective was to develop a post-process machine that performs automated measurement of the bore profile and is capable of detecting waviness. The machine was built using the same measurement system and the same roll-shoe centerless fixture as the grinding machines used for the production of the parts. The machine was designed and set up such that disturbances of the measurement are minimized. It was shown that the machine reaches accuracies close to those obtained by manually operated roundness machines. The cycle time is approximately 4 seconds per part compared to several minutes for manually operated roundness machines. As a second objective, the possibility of measuring waviness directly in the grinding machine was evaluated. Feasible design modifications to reduce the effect of disturbances are very limited in grinding machines, since interference with the grinding process must be avoided. Therefore, analytical methods were developed to reduce these effects and partly restore the original profile. The main disturbances that were addressed are errors due to irregular sampling of the profile, to the frequency response behavior of the gage heads, and to motion of the workpiece center relative to the gage heads. The post-process machine was used as a development and test platform for the analytical methods. To further verify these methods, tests were also conducted in an industrial grinding machine.

Abstract:

Thesis: M. Eng. in Manufacturing, Massachusetts Institute of Technology, Department of Mechanical Engineering, 2015.
Cataloged from PDF version of thesis.
Includes bibliographical references (pages 80-81).
The purpose of this project is to set up a statistical process control (SPC) system in a high volume machining center to reduce the scrap rate and improve the manufacturing quality. The system is demonstrated on a machining center at Waters Corporation as part of a team internship project. This thesis focuses on the gage repeatability and reproducibility study (Gage R&R study) for the implementation of the SPC system. Based on the knowledge about the machining processes and the gages available, we select the proper gages for different dimensions to conduct the Gage R&R study. Gage capabilities are analyzed and root-cause analysis for incapable gages is performed. Related reaction plans are developed and implemented in order to improve the gage capabilities. Discussion about tolerance redesign leads to the adjustment of specifications in the manufacturing area. As a result of these efforts, we find that the existing measurement system is capable for the SPC real time inspection system. As for the final result for this entire project, we demonstrated that with the SPC system, we successfully reduce the scrap rate by half and thus offer substantial cost savings as well as improved product quality.

Abstract:

The goal of this thesis has been to perform research on the relationship between the creative team, software architecture, and game development processes.Researching this relationship was done in three stages. The first stage was a literature review into software architecture and game development. In the second stage a questionnaire was designed based on the literature review, and this questionnaire was then distributed to several game developers. In addition to querying the game developers on their knowledge on the field, they were also asked whether or not they would be willing to answer a set of follow-up questions later.The responses to the questionnaire provided a lot of answers, but also gave rise to new questions. In the third stage these new questions were incorporated into a follow-up survey which was distributed to those respondents whom had previously answered that they were willing to answer follow-up questions.The problem definition has been divided into five research questions according to the Goal Question Metric approach. Supported by the literature review and the responses to both the questionnaire and the survey, these five research questions have been answered in detail in Chapter 11: “Research Conclusions”.The results from this thesis is not generalizable to all game developers, but provides a very interesting glimpse into how the creative team is affected by, and is allowed to affect, the software architecture and tools used, as well as the game development process.

Abstract:

The purpose of this Grounded Theory study is to investigate the positive and negative effects of Game Analytics and how it may affect the Game Design process within the Game Development process. This is done by reviewing and observing available source material appertaining to Triple AAA Games Industry Experts regarding the topics of Game Analytics, Gameplay, Game Design as well as Game Development. The source material consists of publications, presentations, articles and lectures directly linked to the aforementioned areas in which will be used to reinforce the theory. Through the collected data the theory will emerge which will present the potential positive and negative aspects as well as issues regarding using Game Analytics to track the player’s behavior in order to directly affect and possibly alter the Game Design process. The results highlight the positive aspects of using Game Analytics in the Game Design process in which indicate that it is helpful for the Game Designer to utilize the player’s behavioral data captured from Gameplay. This acts as a powerful extension over the traditional design process. The negative aspects have indicated that Game Analytics is a new practice and is still met with prejudice as it requires a lot of knowledge to be able to be used right in the Game Design process. The theory indicates that Game Analytics is a step in the right direction as it enables the Game Designer to gain further understanding of their players with the end goal of creating a better Gameplay experience.
Syftet med denna Grounded Theory studie är att undersöka de positiva och negativa effekterna av spelanalys och hur det kan påverka speldesign processen inom spelutvecklings processen. Detta görs genom att granska och observera tillgängligt källmaterial som är relaterat till Triple AAA spelindustrin och experter inom spelbranschen med fokus på spelanalys, spelande, speldesign och spelutveckling. Källmaterialet består av publikationer, presentationer, artiklar och föreläsningar som är direkt kopplade till ovannämnda områden som kommer att användas för att förstärka teorin. Genom det insamlade källmaterialet kommer teorin att utvecklas som presenterar de potentiella positiva och negativa aspekter om att använda spelanalys för att spåra spelarens beteende för att direkt påverka och eventuellt förändra speldesign processen. Resultaten framhäver de positiva aspekterna av att använda spelanalys i speldesign processen som tyder på att det är fördelaktigt för speldesignern att utnyttja spelarens beteenderelaterade data tagna från spelet. Detta fungerar som en kraftfull förstärkning av speldesign processen jämfört med den traditionella design processen. De negativa aspekterna har indikerat att spelanalys är en ny praxis och fortfarande kräver en hel del kunskap för att kunna användas direkt i spelet designprocessen. Teorin indikerar att spelanalys på väg i rätt riktning eftersom det gör det möjligt för speldesigners att få djupare förståelse om hur sina spelare beter sig för att nå sitt slu*tmål vilket är att skapa en bättre spelupplevelse.

Abstract:

The aim of this thesis is to make a contribution to practice and knowledge regarding the nature and management of the computer game development process. The practice-based motivation is that the computer game industry needs a process management approach that · does not stifle creative practices and yet still facilitates process control. This practical impetus merges with gaps in our scholarly knowledge of the ISD process. One particular · gap is what the software development process is like in a computer game development context. Inspired by these practical and theoretical motivations, I conducted an in-depth case study of a computer games studio in Singapore between 2004 and 2006. Having collected and analysed data pertaining to numerous computer game projects in that time and context some key insights emerged. Firstly the ISD process in a computer game development context is contrapuntal - a harmonious combination of flux and sedimentation, Le. improvisation - the reworking of something. The sedimentation or control of designs in-use was an outcome of the sedimentation of meaning enabled through the intensive practice of play-testing. An aspect of this intensive practice was · emotion reflexion - being reflexive over how the game made the developers feel. .. Secondly, the study revealed the important role of emotions in the process/context, which r had motivational and disruptive potential. It was suggested that there is a need to manage the meaning of development 'events' and yield uplifting interpretations so as to minimise disruption to the process. Thirdly, another source of potential disruption was the interdisciplinary nature of the game development context.The findings infer that interdisciplinary knowledge sharing can enhance participation and thereby improve the game development process.

Abstract:

This thesis provides a theoretical and empirical examination of the contentious “sovereignty” dispute between Taiwan and China, especially following the signing of the Cross-Strait Economic Cooperation Framework Agreement (ECFA) in 2010. Distinctive from many contemporary studies of cross-Strait relations, this research analyzes Beijing’s and Taipei’s political agendas regarding sovereignty in the broader context of East Asian economic integration, as the ECFA is in fact the byproduct of their regional strategies. Commercial diplomacy and interdependence theory constitute the theoretical framework of this thesis. Moreover, this thesis employs various definitions of sovereignty in order to evaluate the extent to which China has impacted upon Taiwan’s sovereignty in the process of economic integration. By employing document analysis and elite interview methodologies, this thesis finds that Taipei has a limited ability to protect its sovereignty from China’s commercial diplomacy in the post-ECFA era. This outcome can be explained by Beijing’s efforts to marginalize Taiwan during the construction of East Asian regionalism, which has driven Taipei to shift its strategy from confrontation to cooperation with Beijing so as to secure its economic and sovereignty interests. To date, economic integration features centrally in Taiwan’s new Mainland policy. This has increased the degree of Taiwan’s economic dependence on China, which gives greater scope for Beijing to wield commercial diplomacy to infringe upon Taiwan’s domestic, functional, and de jure sovereignty. This thesis makes two overall contributions. The most significant contribution of this thesis is its pioneering research approach, which analyzes how China and Taiwan reconcile their economic interests and sovereignty concerns through the lens of commercial diplomacy. Furthermore, by categorizing sovereignty according to its different aspects, this thesis also contributes to the understanding of the effectiveness of China’s commercial diplomacy in furthering its sovereignty interests with regards to Taiwan.

Abstract:

The concept of open innovation has received increased attention among practitioners as well as in academia in recent years. It provides a conceptual platform for understanding how external sources of knowledge drive internal growth. In addition, it also addresses the internal configurations needed for managing a more externally oriented innovation process. However, many firms still experience major managerial challenges in trying to adopt the principles of open innovation. The perhaps most important challenge in realizing the potential benefits of open innovation lies in modifying existing innovation activities and processes to incorporate the principles of open innovation, rather than creating something completely new. Therefore, the purpose of this thesis is to study the problems and opportunities arising when firms attempt to integrate open innovation activities within their development processes. Empirically, the results are based on three exploratory case studies within the process industries. In total, this thesis is based on 73 interviews from 2 process firms and 9 equipment suppliers to the process industries. Data was gathered in several different countries, and collectively these firms represent perspectives from Sweden, Norway, Finland, Switzerland, Germany, The Netherlands and The United Kingdom.Three papers are appended with the thesis. Paper I studies the overall challenges of integrating open innovation activities within an existing product development process. The key contribution is the enactment of a practitioner-oriented work model, named the open Stage-Gate model, which exploits the advantages of "openness" while simultaneously capturing the benefits deriving from the systematic and structured approach implied by the Stage-Gate process. Paper II studies a concrete application of open innovation by focusing on the development and installation of new or upgraded process equipment in process plants where collaborative efforts by a process firm and various suppliers of process equipment often are required. The analysis focuses on problems and opportunities in different stages of the equipments lifecycle and finds that the content and the intensity of the collaboration should be tailored to the different stages of the equipment's lifecycle. As such, the conclusions highlight the fact that being totally open in development activities is not always the most suitable option. Instead, different degrees of "openness" may be suitable at different stages. Paper III studies collaboration in the later operational stages of a process equipments lifecycle, from an equipment supplier perspective. The results presented in this paper underscore the importance of collaboration in the operational stages as these stages are critical to facilitate technology transfer and production performance.

Abstract:

In recent decades, what could be considered a gamification of the world has occurred, as the ties between games and activism, games and war, and games and the city grow ever stronger. In this book, Anne-Marie Schleiner explores a concept she calls 'ludic mutation', a transformative process in which the player, who is expected to engage in the preprogramed interactions of the game and accept its imposed subjective constraints, seizes back some of the power otherwise lost to the game itself. Crucially, this power grab is also relevant beyond the game because players then see the external world as material to be reconfigured, an approach with important ramifications for everything from social activism to contemporary warfare.

Abstract:

The rapid developments in new communication technologies have facilitated the popularization of digital games, which has translated into an exponential growth of the game industry in recent decades. The ubiquitous presence of digital games has resulted in an expansion of the applications of these games from mere entertainment purposes to a great variety of serious purposes. In this edited volume, we narrow the scope of attention by focusing on what game theorist Ian Bogost has called 'persuasive games', that is, gaming practices that combine the dissemination of information with attempts to engage players in particular attitudes and behaviors. This volume offers a multifaceted reflection on persuasive gaming, that is, on the process of these particular games being played by players. The purpose is to better understand when and how digital games can be used for persuasion by further exploring persuasive games and some other kinds of persuasive playful interaction as well. The book critically integrates what has been accomplished in separate research traditions to offer a multidisciplinary approach to understanding persuasive gaming that is closely linked to developments in the industry by including the exploration of relevant case studies.

Abstract:

The science and practice of management are presented from a completely new, original author's point of view — as a social action of managers who implement given social roles. In existing theories over the past 100 years, management has been considered as a set of functions, as a process, as a talent, but not as a social action that is carried out by a specific person representing a specific social stratum — managers. Sometimes the theory is too boring and difficult to understand and implement them in practice in the management of specific companies. In this book, the author presents the theory of management as an exciting game that is played not only by managers, but also by staff, consumers, and competitors… In each section, the reader is offered training tasks aimed at developing practical management skills. It will be of interest to entrepreneurs, managers, managers, undergraduate and graduate students studying in the field of "Management", "Economics", "innovation", as well as a wide range of readers interested in management and personal development.

Abstract:

The terrorist attacks of September 11, 2001, this chapter observes, gave rise to a dédoublement du droit pénal, or division of criminal law. A ‘criminal law of the inhuman, which speaks to the call of universalism’, confronted ‘a criminal law of the enemy, which assumes that each state can wage war against terrorism as it pleases’, and poses a threat to peace. The chapter urges reinforcement of the former—and with it, humanism—through reinforcement of a ‘work in progress’ that began operations in 2002, when the International Criminal Court began operations.

Abstract:

Propulsion shaft alignment is a necessary and crucial step in the ship construction process, with manning and schedule constraints requiring accurate results as efficiently as possible. There are two methods for measuring the bearing loading along the shaft line: strain gages and load cells. The legacy method for using strain gages required a lot of man power and the legacy method for using load cells was dependent on the quality of machinist made available. Strain gages are the transducers of choice for measurement; however the data acquisition, especially for ships with long shafting systems, can require many strain gage positions and personnel to conduct tests. Load cells are used to validate the accuracy of the strain gage method and to calculate the shaft runout at each bearing location.

Abstract:

The freight railway industry relies on the interchangeability of coupling system parts (i.e., couplers, locks, throwers, pins, knuckles). Variability in the dimensions of the components affects the ability to change parts efficiently and the performance of the components. Because of the complex shapes and dimensions involved, it has been difficult to identify the component causing most of the problems for a combination of coupling system parts. Transportation Technology Center Inc. (TTCI) has developed a digital E-type coupler gage that can be combined with 3-dimensional scanning technologies to help railroads and manufacturers find areas that may be causing fitment problems. Physical gages are also being developed for use in production and field environments. The digital and physical gages can be used for fitment quality checks by the railroads and manufacturers. The digital gage requires a laser scanning of the coupler in question to be completed. A 3-dimensional scan of a coupler can be overlaid with the digital gage to find the dimensions causing a problem. Though it is currently a destructive method, further development of scanning technology could make the process more efficient and nondestructive. Using a combination of the digital and physical gages with the proper procedure may reduce the number of problems with properly fitting components and premature failure of couplers in service.

Abstract:

Abstract The objective of this paper is to demonstrate the flexure properties of ABS plastic in a 3D printed object as a process to enable embedded pressure sensing capabilities. Developing the potential for non-static 3D parts broadens the scope of the fused deposition modeling (FDM) process to include printing ‘smart’ objects that utilize intrinsic material properties to act as microphones, load sensors, accelerometers, etc. In order to demonstrate a strain-based pressure transducer, strain gauges were embedded either directly on top or in the middle of a flexible ABS diaphragm. Securing a strain gage directly on top of the diaphragm traced a reference pressure more closely than diaphragms with the strain gage embedded halfway into the diaphragm. To prevent temperature-related drift, an additional strain gage was suspended above the secured gage, inside the 3D printed cavity. The additional gage allowed for a half-bridge circuit in lieu of a quarter-bridge circuit, which minimized drift due to temperature change. The ABS diaphragm showed no significant signs of elastic hysteresis or nonlinear buckling. When sealed with 100% acetone, the diaphragm leaked ∼50x slower than as-printed sensors. After pressurizing and depressurizing the devices multiple times, they output pressure readouts that were consistent and repeatable for any given pressure within the operational range of 0 to 7psi. The repeatability of each of the final generation sensors indicates that ‘smart’ objects printed using an FDM process could be individually calibrated to make repeatable recordings. This work demonstrates a concept overlooked previous to now — FDM printed objects are not limited to static models, which lack dynamic motion of the part as an element of design. Altering FDM’s bottom-up process can allow for easily embedding sensing elements that result in printed objects which are functional on the mesoscale.

Abstract:

Surface texture of engine components such as crankshafts and camshafts is one of the most important factors that determine the performance, efficiency and the operating life of an internal combustion engine. Current practices and the challenges faced by design engineers in specifying the target surface topography to meet these goals have been reviewed. Once specified, the surface texture must be measured fast, accurately and repeatably in the rough environment of an engine manufacturing plant. The key components of an automated skidded surface finish measuring gage designed with these criteria in mind are described in this paper. The gage has 7 axes of motion and 3 stylus probes oriented in the axial and radial directions to take axial and facial measurements on journal and cam lobe surfaces and thrust bearing surfaces. The selection of surface texture parameters to best describe the desired surface texture of these engine components was investigated. The final stage of surface preparation is often the superfinishing process. The measurement gage must be able to provide the sensitivity and repeatability that are required for measuring the finely finished surfaces generated by this process. Typical surface texture results of a superfinishing process achieved on crankshafts are described. The results of a Gage Repeatability and Reproducibility (R&R) study performed on the surface texture measuring gage are presented.

Abstract:

Detailed transient thermal models have been developed to simulate a heat flux gage calibration process capable of generating high heat flux levels. These heat flux levels are of interest to the reciprocating and gas turbine engine industries as well as the aerospace industry. The transient models are based on existing, experimentally validated steady state models of a cylindrical blackbody calibration system. The steady state models were modified to include insertion of a heat flux gage into the hot zone of the calibration system, time-varying electrical current that passes through the resistance heated blackbody, and the resulting heating of the heat flux gage. Heat fluxes computed using detailed transient models were compared to experimental measurements. The calculated and measured transient heat fluxes agreed to within 2 percent, indicating that the models had captured the physical phenomena in the transient calibration. The predicted and measured transient heat fluxes were also compared for two different blackbody configurations. The effect of convection on the blackbody extension was evaluated and found to be a minor factor.

Abstract:

20-High rolling mills process high strength and/or very thin non-ferrous and ferrous metals using a complex, cluster arrangement of rolls. The 20-high roll cluster arrangement achieves specific flatness goals in the thin sheet by delivering maximum rolling pressure while minimizing the deflections of the small diameter rolls. 20-high mills also employ flatness control mechanisms with sophisticated actuators, such as those to shift intermediate rolls and deflect backup bearing shafts. The purpose of this is to compensate for variations in strip dimensional and mechanical properties which can cause poor flatness control quality from discrepancies in work-roll gap profile and distribution of rolling force. This suggests that the random property differences in the rolling parameters that substantially affect the flatness must be directly accounted for in flatness control algorithms in order to achieve strict flatness quality. The use of accurate mathematical models that account for the rolling pass target gage reduction can optimize the flatness control actuators and help gain an advantage in the thin gauge strip competitive global market. Based on the expected process parameter variations and nominal mill set-points (speed, tension, gage reduction, etc.), the mill’s process control computer should determine the probability that target flatness control quality will be met for a required length of strip. The process computer should then either modify the number of rolling passes or adjust the thickness reduction schedule before rolling begins to secure an improved flatness probability estimate if the probability of achieving target strip flatness is too low for the required deliverable quality. Therefore, this research integrates 1) 20-high roll-stack mill mathematical modeling, 2) probability distribution data for random important rolling parameters, 3) reliability-based models to predict the probability of achieving desired strip flatness, and 4) optimization examples. The results can be used to reduce wasted rolled metal from poor flatness before rolling.

Abstract:

Recent gage restraint measurement system (GRMS) developments include the redesign of GRMS vehicles using a deployable split-axle instead of a freight truck mounted split-axle. This new test configuration results in boundary condition changes in the applied loads and split axle location, which influence test results. To ensure the equivalence of test results from these two systems, a comprehensive evaluation of the mechanistic basis for previous GRMS rulemaking was conducted and coupled with a fundamental investigation of factors influencing GRMS performance and inspection accuracy followed by field-testing to verify conclusions. Comparison tests between the original GRMS vehicle design and the redesigned vehicles identified the need to enhance the current gage widening ratio (GWR) equation to accommodate the increased range of vertical test loads represented by the different GRMS vehicles. GWR has been the leading source of test result discrepancies between the original GRMS design and redesigned vehicles over the same territory. The discrepancy between the inspections likely resulted from the increased range of vertical test loads represented by the distinct test vehicles, since GWR has treated vertical load as a constant. The Gage Widening Projection (GWP) parameter was proposed to replace GWR as a result of an ongoing investigation. GWR was originally developed as an indicator of fastener and tie performance by providing an extrapolated total gage widening deflection at a limiting load condition. Testing at the limiting load condition is not conducted because of the potential for damage to track components. A deflection at a lower load is extrapolated based on conservative track load-deflection behavior to the limit load, which represents an extreme but not unexpected gage widening event. The concept behind both GWP and GWR is similar. However, the GWP parameter includes vertical load as a variable, where GWR treated vertical load as a constant. The large variation in vertical load represented by the various test scenarios requires the consideration of variable vertical load in the extrapolation process to ensure an equivalent basis for inspection and safety. Based on analytical modeling and field-testing, the GWP parameter was found to perform more consistently between vehicles than GWR. A limiting condition based on a combination of deflection and load was selected to provide comparable inspection results and safety for both parameters. Additional testing has been conducted to further evaluate the data and indicates excellent performance of the GWP parameter, and perhaps merits further consideration regarding the limits.

Abstract:

In this paper, a diagnostics and root-cause analysis scheme for real-time monitoring of process quality of pull-type fastening operations is presented. The proposed approach encompasses (1) integrating a strain gage, an LVDT (Linear Variable Differential Transducer), a pressure sensor, and a mote on a pull-type pneumatic tool; (2) monitoring process parameters coming from embedded sensors communicated wirelessly via the mote and generating process signatures in real-time; and (3) detecting anomalies in real-time in the process signatures for quality problems related to the grip length deviation in pull-type fastening operations. A feature extraction-based diagnostic methodology is employed to make decisions in terms of grip length deviations in the form of normal grip, over grip, and under grip. The process signature of strain-over-displacement versus displacement has shown unique features that are extracted to determine the quality of the fastening process. In addition, air pressure is also continuously monitored in real-time during the process since it also affects the quality of the fastening operation. The overall architecture has been implemented on a Huck45 pull-type tool, which is a hand-held pneumatic fastening tool used extensively in the aerospace industry, with lock-bolt fasteners. The prototype has been tested under a variety of experimental settings in order to verify its effectiveness and validate its performance over a wide range of different sheet metal thicknesses used for fastening. The experiments have shown that the proposed approach is successful, with an accuracy of over 96%, in determining the quality of fastening operations and in communicating the quality information in real-time using a wireless network to a server. Overall, the proposed architecture has merits to (1) detect quality problems in real-time during the fastening process and (2) reduce post-process inspection, thereby improving quality while reducing cost. In addition, the proposed approach facilitates 100% data collection on each fastener as opposed to traditional statistical process control (SPC) techniques, which rely on sampling.

Abstract:

In certain situations, train car containers that carry hot metal have been overfilled, which necessitated the replacement of very costly car parts. Therefore, it is desirable to predict the amount of fluid needed at all times in order to know when to divert the flow of molten steel from the car. This study showed that the level of fluid in a container can be controlled even when the amount of fluid inside the container is not visible. When strain gages are effectively installed they can be used to continuously calculate the weight of a system as the strain increases, although only the final total weight is of concern. Strain gages can be positioned in safe locations on the spanner bolster of a hot metal car. The gages are installed such that the thermal and axial strains cancel out, ultimately leaving only the value for the weight of the loaded car. Once the gages are installed, they are calibrated when the system is full. For all subsequent loading periods, the strain gages report a linear strain increasing until it is equal to the original full calibration value. This then signals the operator to divert the flow of steel. If the inside of the container deteriorates over time, the strain that governs the shutoff remains the same although the fluid level is slightly lower. In the event of skull (leftover steel in the container), the maximum strain remains the same and the final volume is lower than the initial calibration condition. The objective in all cases is to avoid overflow of fluid from the car. This investigation showed that the amount of fluid in a train car that carries molten steel can be known at all times during the filling process. It is supported with manual calculations, finite element analyses, and laboratory experiments.

Abstract:

In the practice of a teacher-psychologist at the School of Distance Education, the game “Sign me up as an astronaut”, developed by the author, was tested, aimed at developing the skills of social and psychological interaction in younger adolescents with disabilities through the awareness and strengthening of personal resources by means of game psychocorrection. The specifics of the work of a psychologist at the School of Distance Education are determined by the following circ*mstances: - students have a severe disability and the corresponding psychophysical characteristics: instability of the emotional-volitional sphere, lack of motivation, severe physical and mental fatigue, low level of social skills, etc. - the use of distance educational technologies in psychocorrectional work; - lack of methodological recommendations for psychocorrectional work in conditions of distance technologies with school-age children. Such recommendations are available mainly for adults, they relate to the educational process, but they do not cover the correctional process. There is enough scientific and methodological literature on psychological and pedagogical correction, which is the basis for ensuring the work of a practicing psychologist, but there are difficulties in transferring these techniques, games, etc. - to the remote mode of correctional and developmental work, especially in the form of group work. During the game, various social and psychological situations are solved, which are selected strictly according to the characteristics of the social experience of the participants.

Abstract:

Can online experiences that illustrate the lives of vulnerable populations improve prosocial behaviors and reduce prejudice? We randomly assign 850 individuals to: i) an online game that immerses individuals in the life decisions of a Venezuelan migrant and ii) a documentary about the migration process of Venezuelans to Colombia. Both treatments effectively improve altruism and reduce prejudice towards migrants. The impacts of both treatments are not statistically different in any of the other outcomes that we examine. The effects of the game are mainly driven by changes in perspective-taking while the effects of the video are induced by changes in both empathy and perspective-taking.

Abstract:

Software vulnerability discovery, patching, and exploitation—collectively known as the vulnerability lifecycle—is time consuming and labor intensive. Automating the process could significantly improve software security and offensive hacking. The Defense Advanced Research Projects Agency’s Cyber Grand Challenge supported teams of researchers from 2014 to 2016 that worked to create these tools. China took notice. In 2017, China hosted its first Robot Hacking Game, seeking to automate the software vulnerability lifecycle. Since then, China has hosted seven such competitions and the People’s Liberation Army has increased its role in hosting the games.

Abstract:

The People’s Republic of China (PRC) is in the process of modernization, which it expects to achieve by 2035. This requires a national indicator to gauge the progress and level of the country’s modernization drive. This working paper provides an indicator that assesses the progress in the PRC’s modernization journey, and applies this modernization indicator—structured on thematic categories, subcategories, and intersection—to the PRC’s performance, which is then compared with countries of the Organisation for Economic Co-operation and Development and the G20. The paper also examines four major policy implications of this modernization for the PRC, which will be more durable and successful if coupled with effective division of labor and synergy with stakeholders.

Abstract:

This research sought to understand the impact of probation inspection on probation policy, practice and practitioners. This important but neglected area of study has significant ramifications because the Her Majesty’s Inspectorate of Probation has considerable power to influence policy through its inspection regime and research activities. The study utilised a mixed methodological approach comprising observations of inspections and interviews with people who work in probation, the Inspectorate and external stakeholders. In total, 77 people were interviewed or took part in focus groups. Probation practitioners, managers and leaders were interviewed in the weeks after an inspection to find out how they experienced the process of inspection. Staff at HMI Probation were interviewed to understand what inspection is for and how it works. External stakeholders representing people from the voluntary sector, politics and other non-departmental bodies were interviewed to find out how they used the work of inspection in their own roles. Finally, leaders within the National Probation Service and Her Majesty’s Prisons and Probation Service were interviewed to see how inspection impacts on policy more broadly. The data were analysed thematically with five key themes being identified. Overall, participants were positive about the way inspection is carried out in the field of probation. The main findings are: 1. Inspection places a burden on practitioners and organisations. Practitioners talked about the anxiety that a looming inspection created and how management teams created additional pressures which were hard to cope with on top of already high workloads. Staff responsible for managing the inspection and with leadership positions talked about the amount of time the process of inspection took up. Importantly, inspection was seen to take people away from their day jobs and meant other priorities were side-lined, even if temporarily. However, the case interviews that practitioners take part in were seen as incredibly valuable exercises which gave staff the opportunity to reflect on their practice and receive positive feedback and validation for their work. 2. Providers said that the findings and conclusions from inspections were often accurate and, to some extent, unsurprising. However, they sometimes find it difficult to implement recommendations due to reports failing to take context into account. Negative reports have a serious impact on staff morale, especially for CRCs and there was concern about the impact of negative findings on a provider’s reputation. 3. External stakeholders value the work of the Inspectorate. The Inspectorate is seen to generate highly valid and meaningful data which stakeholders can use in their own roles. This can include pushing for policy reform or holding government to account from different perspectives. In particular, thematic inspections were seen to be useful here. 4. The regulatory landscape in probation is complex with an array of actors working to hold providers to account. When compared to other forms of regulation such as audit or contract management the Inspectorate was perceived positively due to its methodological approach as well as the way it reflects the values of probation itself. 5. Overall, the inspectorate appears to garner considerable legitimacy from those it inspects. This should, in theory, support the way it can impact on policy and practice. There are some areas for development here though such as more engagement with service users. While recognising that the Inspectorate has made a concerted effort to do this in the last two years participants all felt that more needs to be done to increase that trust between the inspectorate and service users. Overall, the Inspectorate was seen to be independent and 3 impartial although this belief was less prevalent amongst people in CRCs who argued that the Inspectorate has been biased towards supporting its own arguments around reversing the now failed policy of Transforming Rehabilitation. There was some debate amongst participants about how the Inspectorate could, or should, enforce compliance with its recommendations although most people were happy with the primarily relational way of encouraging compliance with sanctions for non-compliance being considered relatively unnecessary. To conclude, the work of the Inspectorate has a significant impact on probation policy, practice and practitioners. The majority of participants were positive about the process of inspection and the Inspectorate more broadly, notwithstanding some of the issues raised in the findings. There are some developments which the Inspectorate could consider to reduce the burden inspection places on providers and practitioners and enhance its impact such as amending the frequency of inspection, improving the feedback given to practitioners and providing more localised feedback, and working to reduce or limit perceptions of bias amongst people in CRCs. The Inspectorate could also do more to capture the impact it has on providers and practitioners – both positive and negative - through existing procedures that are in place such as post-case interview surveys and tracking the implementation of recommendations.
