This paper discusses a challenge-based, collaborative, community-situated STEM learning environment - C3STEM that is aligned with the next generation science standards. In C3STEM, students synergistically learn STEM (Science, Technology, engineering and Mathematics) and CS (computer Science) concepts by solving realistic problems that provide a framework for applying scientific and engineering practices. A recent study conducted with 26 high school students in middle Tennessee showed that our approach resulted in the students making significant learning gains in both fundamental STEM and computational concepts. Furthermore, they were successful in working collaboratively in small groups to find good solutions to an overall challenge problem on optimizing traffic flow through adjacent city intersections. We discuss how students worked through the two components of the C3STEM system: CTSiM (Computational Thinking using Simulation and Modeling) and C2SuMo (Collaborative Cloud-based Scaled up Modeling), present the experimental study we conducted, and discuss the results in detail. We end the paper with a summary of our accomplishments, and directions for future research. © American Society for engineering Education, 2015.

This paper addresses the study of the variable failure rate of high-voltage circuit breaker by using the Weibull distribution method to set time-based maintenance schedule properly. Power circuit breaker is installed in the substation in varied configurations, the case study for compared with, Main and Transfer bus arrangement, and Breaker and A Half bus arrangement. These are used more in substation of Thailand. From the numbers of failure data of power circuit breaker in 230-kV level, recorded by maintenance engineers of Electricity Generating Authority of Thailand's transmission network in the period of 1991-2011. The Weibull distribution is the well-known method to analyze electrical equipment to calculate the failure rate and Mean Time Between Failure of each part of power circuit breaker. After getting Mean Time Between Failure, the parts can categorized and the time-based maintenance schedule can be set consequently. This schedule replacement of such subcomponents usually decreases the total failure rate designated as variable failure rate of high voltage equipment. The results from the table of maintenance schedule by categorizing each part of power circuit breaker with the new replacement subcomponent group show that the failure rate of power circuit breaker can be diminished and it helps to plan maintenance schedule, and also to store up parts of power circuit breaker properly, which will reduce the cost of power circuit breaker maintenance as well.

One of the most valuable assets of an organization is its organizational data. The analysis and mining of this potential hidden treasure can lead to much added-value for the organization. Process mining is an emerging area that can be useful in helping organizations understand the status quo, check for compliance and plan for improving their processes. The aim of process mining is to extract knowledge from event logs of today’s organizational information systems. Process mining includes three main types: discovering process models from event logs, conformance checking and organizational mining. In this paper, we briefly introduce process mining and review some of its most important techniques. Also, we investigate some of the applications of process mining in industry and present some of the most important challenges that are faced in this area.

What if the boring classroom experience can become an immersive, effective and engaging game for both the student and instructor? What if a student could be motivated to accomplish more than just the learning requirements of a class? To make these things real, we propose ChallengeIt: a mobile application that allows students to compete with one another on challenges in their classrooms in a fun and interactive manner. The classroom can now be supplemented with a targeted 'game', where students can earn points by completing challenges, and having their instructors review those answers and award points. And students are free to use any medium or combination of media with which they prefer to respond to these challenges (text, PDF, photos, videos, etc.). This will make them able to always participate in the class (both at school and at home) in a way that makes them most comfortable. If the instructor so chooses, real-world problems could also be introduced into our solution, thereby allowing student efforts to be channeled into real-world solutions. In this paper we will introduce our ChallengeIt interactive game and cover the design and development details from a software engineering aspect. © 2015 IEEE.

The Discrete-Event Modeling and Simulation (DEVS) formalism has been successfully used to model systems whose behavioral state changes based on trigger events. The purpose of this project is to explore the extension of DEVS beyond the modeling of event driven systems, focusing on the application of DEVS to changes in human behavior as driven by emergency events. The objective is to build a modeling and simulation framework for human behavior in emergencies that could easily be extended and built upon in the future. Here we introduce the development of a suite of Cell-DEVS models representing aspects of human behaviors, and the simulation and a detailed analysis of this suite of models. This suite of models explored random and controlled human behaviors, as well as implementing psychological conditions such as herd following. The end state is the development of a repository for these models to serve the DEVS community. © 2015 IEEE.

This paper is focused on the analysis and design of the capacitive plates of the capacitive wireless power transfer system. The coupling structure resembles a loosely coupled capacitor. The electric field coupling interface is the most vital part of the wireless technology. The coupling interface determines the capacitance of the coupling capacitors, maximum power transfer, frequency and overall efficiency of the system. The paper is dedicated to understand the behaviour of the system with respect to the structural construction, frequency of operation and factors that affect the power transfer of the system. The various arrangements and configurations of the capacitive power transfer (CPT) are discussed. The important factors affects the value of coupling capacitance are discussed. Based on results obtained from the analysis, a design guide line is laid out for the construction of the coupling capacitors. The design guidelines addresses critical issues such as operational voltage, temperature stability and selection of the dielectric material. The construction of the system is simple, rugged and inexpensive, which makes it a great contender among the other wireless technology.

The paper outlines a capacitive power transfer (CPT) system for higher power applications. The paper summarizes the operating principle, power electronics requirement and modeling of a basic CPT system. The high frequency converter is the drive force of the contactless system. The high frequency converters found in literature are discussed with their advantages and their drawbacks. With the knowledge of the converters used, an existing topology is modified to fit the capacitive interface of the capacitive power transfer system. The modified LLC resonant converters has several advantages over the traditional converters used for contactless CPT .The converter has a very high power density and can be used for very high power applications. One of the greatest advantages the modified LLC resonant converter is the ability to work off resonance and the inherent ability to buck or boost as per its gain plot. The converter exhibits efficiencies greater than 90%. The design of the proposed topology along with its advantages over the existing topologies for small distance applications are listed.

2015 122nd ASEE Annual Conference and Exposition

作者： Babiceanu, Radu F. Department of Electrical Computer Software and Systems Engineering Embry-Riddle Aeronautical University Daytona BeachFL United States

During the last academic year, the electrical, computer, software, and systems engineering Department at Embry-Riddle Aeronautical University started an innovative effort to integrate a series of graduate systems engineering and software engineering courses. The advent of embedded systems and cyber-physical systems, as integration of computation, networking and physical systems and processes, and, consequently, the goal to impart the needed knowledge to design and lead the operations for such systems, is one motivation. The other significant drive to pursue the software and systems engineering integration project is the ubiquitous use of integrated engineering and software systems of all sizes and complexity levels in the recent years. This work reports on the preparation, teaching pedagogy, class experience, and evaluation of the accomplishment of the course learning objectives for the combined offering of the "engineering Project Management" and "software Project Management" courses. Given the fact that the large majority of the systems built today include both hardware and software components, the combined offering emphasizes the benefits gained by the graduate engineering students when exposed to an integrated software and systems engineering development effort, characterized by contractually-defined system performance, risk, cost, and delivery schedule. As such, the active learning teaching practice implemented in the combined project management offering is the continuous student exposure to a mimicked integrated development environment resembling their future work positions, in which students ought to provide system-optimized solutions, rather than component-best solutions, within the performance-risk-cost-schedule framework. © American Society for engineering Education, 2015.

The paper analyses the efficiency of the Information Technology (IT) for Domain-Specific Mathematical Modelling (DSMM). IT DSMM was developed to meet the shortcomings of the IT for Domain-Specific Modelling (DSM). IT DSMM allows us to develop metamodels in the different mathematical semantics and thus to increase the level of adequateness of models to the modelled domains. It also reduces an amount of operations needed for the development of metamodels and models of software systems. The optimization problem of choosing the most effective IT by selection and comparison of the multiple features inherent to DSM, DSMM and GPM (General Purpose Modelling) is solved. © 2015 IEEE.
