Construction and Practices of the Course of Software Process & Tools Oriented Certified in Engineering Education

In recent years, it is the general trend to adopt the standards of international engineering education certification to construct curriculum. "Software Process and Tools" is one of the core courses of Harbin Institute of Technology's software engineering undergraduate training program. Focusing on the construction work and practical exploration of the course in the process of reforming the software engineering professional curriculum system, and how to achieve the standards of engineering education certification, This paper makes a review and summary. This paper focuses on the status and the role of the course in the whole curriculum system, as well as project-driven teaching content design and practical teaching methods.And summarizes the experience and results of 3 rounds of teaching practice.     

The disenchantment of affect

In computing design, experience is often broken down, compartmentalized, and engineered: a process that often disenchants the original experience. In this paper, we demonstrate the possibility to design for experience, not by formalizing and rationalizing it, but instead by supporting open-ended engagement and appropriation. We illustrate this approach through Affector, a case study in affective computing, in which we focus on user interpretation and construction of emotional experience over its computational modeling. We derive design and evaluation strategies for enchantment that focus on supporting the ongoing construction and interpretation of experience by human participants over the course of interaction. We suggest that enchanting experiences may be designed only by approaching enchantment obliquely: not by engineering it in, but by providing opportunities where it may emerge.

Glasses-type wearable computer displays: usability considerations examined with a 3D glasses case study

This study presents usability considerations and solutions for the design of glasses-type wearable computer displays and examines their effectiveness in a case study. Design countermeasures were investigated by a four-step design process: (1) preliminary design analysis; (2) design idea generation; (3) final design selection; and (4) virtual fitting trial. Three design interventions were devised from the design process: (1) weight balance to reduce pressure concentrated on the nose, (2) compliant temples to accommodate diverse head sizes and (3) a hanger mechanism to help spectacle users hang their wearable display on their eye glasses. To investigate their effectiveness, in the case study, the novel 3D glasses adopting the three interventions were compared with two existing 3D glasses in terms of neck muscle fatigue and subjective discomfort rating. While neck muscle fatigue was not significantly different among the three glasses (p = 0.467), the novel glasses had significantly smaller discomfort ratings (p = 0.009).

Relevance to Industry: A four-step design process identified usability considerations and solutions for the design of glasses-type wearable computer displays. A novel 3D glasses was proposed through the process and its effectiveness was validated. The results identify design considerations and opportunities relevant to the emerging wearable display industry.     

Parallel Turing Machine,a Proposal

We have witnessed the tremendous momentum of the second spring of parallel computing in recent years. But, we should remember the low points of the field more than 20 years ago and review the lesson that has led to the question at that point whether “parallel computing will soon be relegated to the trash heap reserved for promising technologies that never quite make it” in an article entitled “the death of parallel computing” written by the late Ken Kennedy — a prominent leader of parallel computing in the world. Facing the new era of parallel computing, we should learn from the robust history of sequential computation in the past 60 years. We should study the foundation established by the model of Turing machine (1936) and its profound impact in this history. To this end, this paper examines the disappointing state of the work in parallel Turing machine models in the past 50 years of parallel computing research. Lacking a solid yet intuitive parallel Turing machine model will continue to be a serious challenge in the future parallel computing. Our paper presents an attempt to address this challenge by presenting a proposal of a parallel Turing machine model. We also discuss why we start our work in this paper from a parallel Turing machine model instead of other choices.

Using electronic textiles to implement an acoustic beamforming array: A case study

Highly-automated textile manufacturing equipment has the potential for integrating electronic components into fabric in a low-cost process. These electronic textiles (or e-textiles) have a wide range of potential applications in wearable computing and large-area applications, including medical monitoring, assistance to the disabled, and distributed sensor networks. This paper discusses the design and implementation of a large-scale e-textile that functions as an acoustic beamforming array. The paper conveys the implementation experience and gives results gathered from the prototype. Further, the primary implementation issues and guidelines for future development are identified.     

The LilyPad Arduino: Toward Wearable Engineering for Everyone

Electronic textiles, or e-textiles, are an increasingly important part of wearable computing, helping to make pervasive devices truly wearable. These soft, fabric-based computers can function as lovely embodiments of Mark Weiser's vision of ubiquitous computing: providing useful functionality while disappearing discreetly into the fabric of our clothing. E-textiles also give new, expressive materials to fashion designers, textile designers, and artists, and garments stemming from these disciplines usually employ technology in visible and dramatic style. Integrating computer science, electrical engineering, textile design, and fashion design, e-textiles cross unusual boundaries, appeal to a broad spectrum of people, and provide novel opportunities for creative experimentation both in engineering and design. Moreover, e-textiles are cutting- edge technologies that capture people's imagination in unusual ways. (What other emerging pervasive technology has Vogue magazine featured?) Our work aims to capitalize on these unique features by providing a toolkit that empowers novices to design, engineer, and build their own e-textiles.     

Embodied imagination: a hybrid method of designing for intimacy

Abstract

Situated in the domain of research into mobile, wireless, networked and wearable computing, this exploratory paperintroduces the embodied imagination method and explains how it can contribute to the design process by creating an elastic space of performance that incorporates daily life and personal imagination into the design process. It is based on a study called Placebo Sleeves which was an experiential design phase of a larger project in wearable computing called whisper[s]. The innovation offered by this research is twofold: an integration of previously distinct methodologies, and an interdisciplinary theoretical framework relevant to the design of devices for affective, networked communication. The methodologies are shaped both by user experience models and by performance practices. We also articulate a domain of public dreaming, located at the conjunction of the private, public and secret within human existence, and suggest that shared use of mobile technologies has the potential to be situated there.     

Crafts praxis for critical wearables design

This paper treats contemporary craft as an under-researched resource for wearable computing, and presents some of the alternative values and experiences that contemporary craft may be able to contribute to the design of personal technological products. Through design and implementation of a suite of wirelessly networked ‘Speckled’ jewellery, it considers contemporary craft for its potential as a critical design resource with especial relevance to wearable computing and the broad development of this paradigm into the everyday. ‘Critical design’ is given a working definition for the purposes of the argument, and a friendship group of five women of retirement age introduced as the user group for this research. Current practice in the contemporary craft genre of jewellery is analysed for its potential as a resource for a critical approach to wearable computing, and based on a set of semi-structured interviews with contemporary jewellery practitioners, the paper presents a set of propositions for a critical craft approach to wearables design.

A structured methodology for implementing engineering data management

One of the most significant positive effects on product and process development in recent years has been the application of data management techniques. Engineering data management or product data management is the most promising one. The implementation of engineering data management is heavily dependent on the engineering process and involves the technologies of management, engineering, and information. However, as there is no commonly acceptable approach and methodologies for implementing engineering data management, it’s implementation becomes a bottleneck.This paper presents a structured methodology for the implementation of engineering data management. The approach consists of a series of steps, from business and engineering process analysis, modeling and reengineering, through system design and modeling, to system realization.This research will facilitate engineering process improvement and the planning, design and implementation of engineering data management. Consequently, it will help increase product development capability and quality, reduce development cycle time and cost, and hence increase product marketability.     

Conventional and non conventional body motions modelling and control. Application to the handwriting process

The handwriting process is one of the most important and complex activities of the human body. In recent years, modelling and analyzing and controlling it have received great attention leading to large important motion studies results. This paper attempts to present an overview of recent works about our proposed approaches and other ones to model and control this process. Hence, an overall model of the handwriting process has been proposed and developed by the co‐authors, showing the interest of using the soft computing concepts, namely neural networks and fuzzy logic. The design of this model requires several undertaken steps. Starting from an experimental approach to acquire electromyographic signals and writing positions, different conventional and non conventional models have been proposed. Besides some control strategies have been considered in particular neural and fuzzy approaches in addition to non conventional neural and neuro‐fuzzy Internal Model Control strategy. The proposed global model, inspired from the biological structure system, has been designed and validated through simulation results.     

Configurable chips meld software and hardware

Processors that can be configured by end users promise to combine hardware's speed and efficiency with software's flexibility. Developments in configurable computing increasingly blur the line between hardware and software, a trend that represents a major shift in computing practice. To keep their offerings current and relevant, universities should modify their computer science curricula to better prepare students for this new era. Although hardware design is much more software-oriented now, aspiring computing students still need courses that cover hardware synthesis techniques, codesign methodologies, and module reuse strategies. Students should also experience working in teams. At our institute, we have developed such a new curriculum. By offering several hardware courses at both the elementary and advanced levels, we help students obtain a deeper and broader knowledge of configurable hardware design. Moreover, over the past few years we have invested in the design and construction of several FPGA-based boards for use as teaching platforms. These boards let students gain hands-on experience with technologies they'll use in real-world jobs. For example, using the Labomat board, a three-student team designed and tested a simplified floating-point unit in five three-hour sessions

Recent Advances in Mobile Grid and Cloud Computing

Grid and cloud computing systems have been extensively used to solve large and complex problems in science and engineering fields. These systems include powerful computing resources that are connected through high-speed networks. Due to the recent advances in mobile computing and networking technologies, it has become feasible to integrate various mobile devices, such as robots, aerial vehicles, sensors, and smart phones, with grid and cloud computing systems. This integration enables the design and development of the next generation of applications by sharing of resources in mobile environments and introduces several challenges due to a dynamic and unpredictable network. This paper discusses applications, research challenges involved in the design and development of mobile grid and cloud computing systems, and recent advances in the field.     

Field experience with obfuscating million-user iOS apps in large enterprise mobile development

In recent years, mobile apps have become the infrastructure of many popular Internet services. It is now common that a mobile app serves millions of users across the globe. By examining the code of these apps, reverse engineers can learn various knowledge about the design and implementation of the apps. Real-world cases have shown that the disclosed critical information allows malicious parties to abuse or exploit the app-provided services for unrightful profits, leading to significant financial losses. One of the most viable mitigations against malicious reverse engineering is to obfuscate the apps. Despite that security by obscurity is typically considered to be an unsound protection methodology, software obfuscation can indeed increase the cost of reverse engineering, thus delivering practical merits for protecting mobile apps. In this paper, we share our experience of applying obfuscation to multiple commercial iOS apps, each of which has millions of users. We discuss the necessity of adopting obfuscation for protecting modern mobile business, the challenges of software obfuscation on the iOS platform, and our efforts in overcoming these obstacles. We especially focus on factors that are unique to mobile software development that may affect the design and deployment of obfuscation techniques. We report the outcome of our obfuscation with empirical experiments. We additionally elaborate on the follow-up case studies about how our obfuscation affected the app publication process and how we responded to the negative impacts. This experience report can benefit mobile developers, security service providers, and Apple as the administrator of the iOS ecosystem.     

The Antikythera Mechanism: A Computer Science Perspective

Two thousand years separate us from an ancient Greek computing device known as the Antikythera mechanism. The Antikythera mechanism is an ancient astronomical calculator that contains a lunisolar calendar, predicts eclipses, and indicates the moon's position and phase. Its use of multiple dials and interlocking gears eerily foreshadows modern computing concepts from the fields of digital design, programming, and software engineering. In this article, the author explains the mechanism's operation based on its reconstruction in Squeak Etoys, a multimedia authoring environment primarily designed to help high school students learn scientific and engineering concepts. This paper aims to present the functioning of this remarkable device using working code, the language of our community.
