- A Unique4Ps-Based Approach to Teaching Introductory Software Engineering
Abstract: A Unique4Ps-Based Approach to Teaching Introductory Software Engineering
Author Lili HaiKathleen P. Greenber
Project-based learning environments are often used in the teaching of higher level software engineering courses because of their value in providing students with first-hand experience in the software engineering process; however, adapting this approach for use in the introductory course poses a number of challenges. This paper introduces a teaching methodology which exposes students who have only one software engineering course in 4-year curriculum to a special and stimulating learning environment. The method is based on the concept of the Four Ps in software engineering: people, project, product and process. Compared with using assignments and team-projects in the traditional way, the method requires all students in one class to participate in a single customized real-life project. The project is complicated and large enough to expose students to many key software development disciplines that are harder to teach through small projects; in addition, it gives students the opportunity to participate in project management. By adopting the Unified Software Development Process, the method provides a learning environment that makes it possible for computing students to efficiently learn as much fundamental software engineering knowledge and skills as is possible in one introductory software engineering course. This paper studies the learning elements of this course, including core topics in each of the four Ps, and discusses the method of actively and flexibly using these elements to design the learning environment.

Abstract: Study of the Application of Knowledge Base through New Product Development in the System Integration Industry – Comparison of Case Studies based on different product newness
Author Yen-Ling LiuMin-Sun WuangJen-Lung Ka
The system integration industry involves hundreds of enterprises. In this highly competitive environment, new product development becomes crucial to profitability and competitive advantage. New product development involves several activities, each involving different problems. Enterprises use Knowledge Base (KB) to identify effective solutions to the problems occurring at each stage. Producing system integration products involves both design and customization, and therefore each case is unique. Products at different stages of the development process involve different issues. Additionally there is different application from KB. This study takes different degrees of product newness as a focus for examining both new and upgrade products as variable factor, as well as the issues and support involved in new product development. Six cases are used to analyze KB (Knowledge Base) application. The study shows that enterprises should seek different degrees of support from KB and suppliers when facing different technical and non-technical problems. Regarding technical issues, for really new products it is argument setting of KB application; for upgrade products it is argument setting of KB application. Regarding non-technical issues, for really new products these refer to planned applications of KB; for upgrade products these refer to planned applications of KB.
- Demand-Based Allocation of Police Patrols in a Public Safety Emergency
Response System Using Discrete Stochastic Simulation
Abstract: Demand-Based Allocation of Police Patrols in a Public Safety Emergency Response System Using Discrete Stochastic Simulation
Author Javier Holguín-De La Cru
Our research focuses on assisting current operations of a public safety Emergency Response System (ERS) in a large city in Mexico to achieve the international ideal response time of three minutes maximum based on allocating the optimum number of police patrols. We believe that improvements in patrol response times will strongly improve statistics in the crime prevention and control as well as in the apprehension of presumable delinquents. The city is composed by eight police districts and this research integrates an additional district to four previously evaluated. In this research we first characterized the demand for service and processes linked to the attention of the call and patrol utilization. Next, we built a stochastic simulation model to reproduce current operating conditions to validate its behavior. Ultimately, we identified the optimum number of police patrols required to be allocated as back up inventory in each police quadrant within all districts.

Abstract: Study of the Information Diffusion in the Customer Decision-making Process Based on the Field Theory
Author Ning WangMinjun YangXiaohong ShanNa Yan
In this paper, we abstract a three-dimensional coordinate from the factors which influence information diffusion among customers, construct the information diffusion field, and combine the features of the social network to solve two basic problems in the customer decision-making process: one is what the conditions that make the information diffusion operate are, the other one is what the rule of information diffusion is. With the changing level of consumers’ acceptance to the information, we simulate the diffusion process in social network, and draw the conclusion that the information diffusion field can describe the information diffusion process suitably.

The renewable energy industry has been transformed enormously in the past decade especially after many countries started adopting incentives and mechanisms to increase renewable energy technologies deployment, especially in solar and wind. This has created intense competitive environment among companies at the global level. This paper will look into the different technology strategies that solar and wind energy companies are adopting to stay competitive both economically and technologically. It will investigate how these companies are creating value, capturing value, and delivering value. In addition, the factors, both internal and external, that drive the success for these companies are identified. Five case studies including solar and wind companies from around the world were carried out in order to understand their technologies strategies. Based on this, effective technology strategies to create, capture, and deliver value in the solar and wind renewable industries are identified.
- Transparent Authentication Methodology in Electronic Education
Abstract: Transparent Authentication Methodology in Electronic Education
Author Gary B. WillsRichard M. CrowderDavid ArglesNawfal F. Fadhe
In the context of on-line assessment in Electronic-learning, a problem arises when a student taking an exam may wish to cheat by handing over personal credentials to someone to take their place in an exam; another problem is that there is no method for signing digital content as it is being produced in a computerized environment. Our proposed solution is to digitally sign the participant’s work by embedding voice samples in the transcript paper at regular intervals. In this investigation, we have demonstrated that a transparent steganographic methodology will provide a innovative & novel solution for achieving continuous authentication in an online educational environment by successful insertion and extraction of audio digital signatures.

This paper describes transition of educational process in Siberian State University of Telecommunications and Information Sciences to Bologna-style higher education system based on two main cycles (Bachelor and Master). It considers basic problems of creation of modern educational technologies in higher school and issues of organizational, technical and methodical maintenance of training process. The paper presents the model of electronic dean's office with various subsystems. The authors of this paper discuss alterations in subject – object relations between a teacher and a student in new educational paradigm, when students direct their own learning-cognitive activity. When implementing new pedagogical technologies, such as distance learning, teachers have to face the problem of creation of educational environment allowing students to control such kind of activity. Deficiency of communication during study can cause inability to create favorable psychological climate and comfortable conditions for learning. Lack of communication activity can also lead to decrease of interest in learning up to complete vanish of motivation to study through the new technologies. New educational environment brings about new learning situations and relations.
