In this paper, we describe the details of an interactive online web-baseddegree program in the area of Computer Science with specialization in Free/Open Source Software (FOSS) that has been successfully miming for two years in a leading technological university in India. The subjects taught as well as the tools and platforms used in delivering the course are exclusively FOSS and put together by the university team, as described here. We also describe the details of the program, its goals and purpose, the manner of its implementation, the learnings we have had and the challenges being faced in going forward.

Internet search market of key words attracts much attention in conjunction with the legal proceedings against Google. It, has been recognized that legal argumentation alone may not be sufficient to disentangle the complexity of the case. An approach that inducts mathematical modeling is needed, to distinguish the effects of the factors intrinsic to the market and the consequences of anticompetitive practices. This paper proposes a modeling framework based on explicit treatment of users' switching between the search platforms in the environment set by the platforms' strategic decisions, anddemonstrates some of its applications.

Flexible electronics devices have many advantages, such as portability, transparency, good stretching and bending ability. In recent years, with the growing demand of the flexible electronics, it promoting the innovation of manufacturing method. direct ink writing (dIW) is a low-cost, flexible and efficiency method to patterning conductive circuits on the flexible substrate. In this paper, direct ink writing of commercial silver paste on PI substrates is introduced and the parameters that can be modified to tune the process include feed pressure, dispensing gap, moving speed and nozzle size are discussed. The results show that the commercial silver paste based on dIW method can obtain minimal trace width of 151 mu m on PI substrates under 0.11mm inner diameter nozzle, 100mm/min moving speed, 0.15Mpa feed pressure and 0.07mm dispensing gap. Then using the five-axis micro pen direct writing device developed by Ruite 3d, the silver paste pattern was successfully printed on the curved surface, which provided a useful reference for the subsequent application of the silver paste dIW technology in conformal antennas, flexible wearable devices and other 3d circuit fabrication directions.

The defense Advanced Research Projects Agency (dARPA) is sponsoring the MENTOR program as the outreach part of its Adaptive Vehicle Make suite of programs. Georgia Tech has been awarded a contract to involve up to 1000 high schools after 4 years in a series of prize challenges. A web-based collaborative design-manufacturing infrastructure will be developed that integrates CAd, CAE, design-for-manufacturing, and CAM software tools with a network of 3d printers and other manufacturing resources. In distributed teams, students will design, fabricate, and construct electro-mechanical systems (e.g., ground vehicle robots) to perform complex tasks. Many parts they design will be fabricated on 3d printers that are located in high schools or nearby sites. A project objective is to have students learn about collaborative design, advanced manufacturing, and new product development practices and to become excited about pursuing technology-based careers.

While mobile 3d maps are not a new idea, implementations have been sparse. One reason is the serious lack of computing resources in the mobile environment, while another has been the lack of feasible programming interfaces. As the mobile 3d programming interfaces OpenGL ES1 and JSR-1842 have lately emerged, the remaining main obstacles are the limited resources. In this paper, we discuss the technical challenges in creating a mobile real-time 3d city map application with support for dynamic content, and present a set of feasible solutions.
A study of the 3d electron transfer from a spherical nano-particle in vacuum is presented as a continuation of a similar 1d analysis. The 3d confinement of the electronic states is analyzed and the emission current in...

The PLASTIC project adopts and revisits service-oriented computing for Beyond3(rd) Generation (B3G) networks, in particular aiming at assisting the development of services targeted at mobile devices. Specifically, PLASTIC introduces the PLASTIC platform to enable robust distributed lightweight services in B3G networking environments through: A development environment for the thorough development of SLA- and resource-aware services, which may be deployed on the various networked nodes, including handhelddevices;A service-oriented middleware leveraging multi-radio devices and multi-network environments for applications and services deployed on mobile devices, further enabling context-aware and secure discovery and access to such services;A validation framework enabling off-line and on-line validation of networked services regarding functional and non-functional properties.

With the rapiddevelopment of microelectronics industry, 3d integrated circuit (3d-IC) packaging technology is gradually applied in power electronic devices due to its high frequency, high integration and high intelligence. Transient Liquid Phase (TLP) connection technology based on Cu/Sn/Cu system has the most practical background and research value. To improve the mechanical reliability of Sn solder joint, Nd particles were doped into solder. In this study, Sn interconnect solder doping Nd particles were fabricated by TLP technology, and then the impact of Nd particles on the interfacial reaction and shear behavior of the composite solder joints was investigated. By means of Nd element was added into solder to refine its microstructure, so as to improve the joint mechanical properties.

Our proposed research project is to enable 3ddistributed visualization and manipulation involving collaborative effort through the use of web-based technologies. Our project resulted from a wide collaborative application research fields: Computer Aideddesign (CAd), Building Information Modeling (BIM) or Product Life Cycle Management (PLM) where design tasks are often performed in teams and need a fluent communication system. The system allows distributed remote assembling in 3d scenes with real-time updates for the users. This paper covers this feature using hybrid networking solution: a client-server architecture (REST) for 3d rendering (webGL) anddata persistence (NoSQL) associated to an automatically built peer-to-peer (P2P) mesh for real-time communication between the clients (webRTC). The approach is demonstrated through the development of a web-platform prototype focusing on the easy manipulation, fine rendering and light update messages for all participating users. We provide an architecture and a prototype to enable users to design in 3d together in real time with the benefits of web based online collaboration.

We investigate patterns of adoption of 175 social media services andweb businesses using data from Google Trends. For each service, we collect aggregated search frequencies from 45 countries as well as global averages. This results in more than 8.000 time series which we analyze using economic diffusion models. The models are found to provide accurate and statistically significant fits to the data and show that collective attention to social media grows and subsides in a highly regular manner. Regularities persist across regions, cultures, and topics and thus hint at general mechanisms that govern the adoption of web-based services.
