The positioning of sensors in Wireless Sensor Networks WSNs affect coverage, communication cost and resource management. The effectiveness of these networks is determined to a large extent by the coverage provided by the sensor deployment. Coverage is an important optimization objective in WSN deployments. Sensor positioning alludes to the capabilities of WSNs to `adapt' and `respond', in order to provide an unobtrusive service. In this paper we propose a distributed self-organizing deployment scheme for WSN to maximize coverage of a randomly deployed network. Our scheme is completely distributed and self-adaptive. It requires a node to posses only the local information and is being able to transparently encompass several modes of operations. A node explores an uncovered region around itself. It uses this heuristic to move in the direction where the FoI is uncovered. This proposed technique performs consistently to suit the pervasive needs of an application with centralized [1] and decentralized control for deployment. Extensive simulation results and their comparison with other distributed algorithms show that the performance of D-UREA is efficient with respect to communication and computation.

We propose a simplified analog design cycle to generate reconfigurable and accurate prototype of several analog ICs. On applying the design cycle a comprehensive design methodology is being developed that make designs customizable and adaptable by a field user. The basic design of a second generation current controlled current conveyor is first analyzed to estimate the basic circuit configuration to verify its basic functionality. Secondly using its small signal equivalent model, ac and dc characteristics are being derived in terms of threshold voltage of transistors, present in the circuit. Indeed, with the help of floating gate transistors, which has a feature of post fabrication programmability of its threshold voltage, an accurate and reconfigurable prototype of the design can be obtained. The circuit is simulated using BSIM3 level49 MOSFET models in T-Spice 0.35μm CMOS process. Various Characteristics of CCCII are being derived and estimated their sensitivity with respect to threshold voltage of respective floating-gate transistors. The simulated results demonstrate that by programming threshold voltages, fine tuning of circuit specifications with wide spectrum can be achieved. The designs fabricated using our methodology can be adaptive to any desired value of specification with very high precision (about 13bit programming precision can attain with floating gate transistor). It can also make Analog ICs immune to most drawbacks like processes variations, device degradation by introducing new possibilities such as self correction and adaptability.

In bi-directional multi-antenna relaying with binary network coding, antenna selection can offer the benefits of full diversity at lower complexity. However, the rate at which the antennas are switched can also contribute to the complexity of the relaying scheme. In this paper, we explore a way of reducing this switching rate and study the implications of a reduced switching compared to the optimal antenna selection scheme.

In this paper we point out the relevance of and the need for a theoretical discussion around UX research and practice. Although there is a good coverage of methodological and design related topics in the HCI literature, there is still a lack of theoretical focus in the rapidly increasing work on user experience (UX). We analyzed 122 individual items on theories collected in a CHI'11 special interest group session on UX theories and theoretical frameworks. The data set was filtered and categorized in several iterations, resulting in 56 items distributed over 7 major theory categories and related to 9 relevant disciplines. The categories are an initial mapping of the field and point towards the directions for further conceptual and theoretical clarification. Our results help to explore the multi-disciplinary nature of UX and to build a more solid foundation for UX research and practice. © 2012 Authors.

Course design and development need to be considered in many aspects such as goals, features, resources, and constraints of each institution. Furthermore, it should conform to society's needs and should be improved according to the advances of knowledge. In order to cultivate students' capabilities corresponding to the needs of industries so that they can better cope with the severe competition in today's knowledge economy era, schools should have responsibility and endeavors to instruct students how to acquire innovative knowledge rapidly. In this paper, a systematic method of course development for cultivating the innovative capability of students at university was proposed based on knowledge chain model. An example implemented at Far East University in Taiwan was used to illustrate the feasibility of the proposed method. The concept and method proposed in this paper might be used as a reference and guidelines to promote the education of patent related courses at university. © 2012, Society of Sytematic Innovation.

Flexible job-shop scheduling problem (FJSSP) is an extension of the classical job-shop scheduling problem that allows an operation to be processed by any machine from a given set along different routes. It is very important in both fields of production management and combinatorial optimisation. This paper presents a new approach based on a hybridisation of the particle swarm optimisation (PSO) algorithm with data mining (DM) technique to solve the multi-objective flexible job-shop scheduling problem. Three minimisation objectives - the maximum completion time, the total workload of machines and the workload of the critical machines are considered simultaneously. In this study, PSO is used to assign operations and to determine the processing order of jobs on machines. The objectives are optimised by data mining technique which extracts the knowledge from the solution sets to find the near optimal solution of combinatorial optimisation problems. The computational results have shown that the proposed method is a feasible and effective approach for the multi-objective flexible job-shop scheduling problems.

Recently, a lot of researchers have studied the brain-computer interface (BCI) system, and some systems have already been put to practical use. For instance, the system based on P300 were actively used. However the P300 system requires user's strong concentrations. Therefore it is necessary to introduce information from the EEG signal. This paper tried to investigate a rhythmic after-discharge of transient-VEP by consecutive visual stimulation, and now have examined responses to a variety of stimulation methods.
