Development System

In this study, a low-cost and adaptable isometric strength measurement and exercise development system are described. The implemented system consists of mechanical structure, force measurement sensor, electronic circuit, and computer software. Isometric-isotonic (via spring resistance) strength analysis and various exercise programs can be applied with the system. The developed system has a lower cost compared to its counterparts in the literature and has a structure that can be adapted to different machines and measuring methods. The operability and reliability of the isometric strength measurement and exercise development system have been proven by calibration tests.

The Impact

Abstract A riser is a key component for transporting produced oil and gas from the subsea wells to the surface production vessel. Through nearly 30 years of design and implementation, Steel Catenary Risers (SCRs) have been found to have the advantages of relatively low cost and good adaptability to floating platform’s motion. This paper investigates deepwater SCR system design for the Lingshui 17-2 (termed LS17-2) project. This paper first introduces a SCR system for the LS17-2 project. The field for this project is located in the northern South China Sea, with water depth of 1220m to 1560m. LS17-2 consists of a subsea production system, a deep-draft semi-submersible (SEMI), and an export riser/pipeline. The platform was designed to have a large storage capacity with a variable draft during its operation. Based on deepwater SCR engineering experience, the key SCR design challenges are summarized from the engineering executive perspective. The challenges to the SCR system design for the LS17-2 project include harsh environment condition in South China Sea and the impact on fatigue design for the requirement of 30-years’ service life. They call for design optimization and innovative ideas. The engineering design and analysis are discussed together solutions. To demonstrate the deepwater SCR system design for LS17-2 project, examples are provided to illustrate the challenges and solutions. The experience learned from this paper should have significant relevance to future SCR design.

E-commerce and internet businesses are driving the rapid growth of the domestic IT-ITeS industry, attracting unprecedented global interest and funding. Indian e-commerce and internet companies are growing rapidly with about 460 million internet users and a tele-density of around 85.2%. Increasing penetration of the internet, adoption of smartphones and minimal effort low-cost mobile devices, changing demographics, mobile-empowered youth, and the emergence of tier 2 and tier 3 cities as major shopping hubs have been driving the growth of the industry, with new retail forces shifting its dynamics. Furthermore, the continued growth of large pure-play organisations that are powerhouses has moved retailers' focus to the web channel. These companies are not only becoming gateways to product research, but have also introduced consumers to new ways of viewing the retail process.

Smart spaces are defined as an environment capable of communicating with users in order to support them in achieving a goal. Previously, smart spaces were restricted to closed private areas in a well defined environment. However, factors such as the omnipresence of mobile devices, the advancement in wireless communication, and the low cost of technological infrastructure allows the creation of smart spaces everywhere. One trend that is acquiring relevance these days is to use surrounding public resources to perform tasks on behalf of mobile devices, which are resource constrained. To achieve this, systems should be able to control the access to public resources, minimize possible interference among users, and maintain the purpose of public resources untouched. This work presents a multi-user ad-hoc resource manager for smart urban areas based on previous considerations. The current system helps to avoid conflicts between users by means of a distributed scheme based on social gain for the community. The management is performed without the need of a central infrastructure. Results show that it is possible to discover and manage public resources from mobile devices while handling conflicts in a distributed manner.

The increasing availability of mobile devices in today’s business contexts raises the demand to shift the focus of groupware framework design. Instead of solely focusing on functional requirements of specific application domains or device characteristics, nonfunctional requirements need to be taken into account as well. Flexibility concerning the integration of devices and tailorability of the framework according to different usage contexts is essential for addressing device heterogeneity. Besides flexibility, in order to support the development of real-world applications involving heterogeneous devices, robustness and scalability concerns have to be addressed explicitly by the framework. This article presents Agilo, a groupware framework for synchronous collaboration. The framework incorporates approaches addressing flexibility, robustness, and scalability issues. The combination of these concerns makes it suitable for development of collaborative applications involving up to hundreds of users. As an example application, a commercial electronic meeting system is presented by illustrating typical usage scenarios, explaining applicationspecific requirements and describing the system design.

With the vagaries of nature being unpredictable, it’s now more important to have access to weather forecast for short periods of time. Many businesses, including those in agriculture and the fishing industry, depend on an hourly update of the weather. The access to such weather nowcasting data has, until now, been through traditional media like the television, radio, et cetera, while new media of communication such as mobile devices, have been largely unexplored. The advancement in MEMS (Micro Electrical Mechanical System) technology has now brought forth various sensors that are miniaturized and can be integrated or embedded into various other systems used presently. Environmental sensors that measure weather parameters are miniaturized to fit the size of a mobile. The system aims to integrate these sensors along with a mobile device so as to provide the capability of data measurement to the vast population that use mobile devices and thus create regional grid networks. The system aims to use the mobile for updating weather parameters as well to be the focal point of communication of the weather nowcasting information. As a result, the mobile device would provide targeted distribution of the weather information, which is more advantageous than the traditional means of mass distribution of information; also, as mobile technology acts as a focal point of gathering weather related parameters, it provides a twofold advantage for setting up a low cost, region specific weather monitoring system.
