Cell selection in current LTE-Advanced depend on reference signal received power or reference signal received quality which results to low user association probability. Therefore, we propose an aggregate objective cell selection technique based on enhanced inter-cell interference coordination technique developed by 3GPP in Rel-10 known as almost blank subframe. We also adopt the use of cell range expansion technique as means to encourage offloading. Cell range expansion was introduced in LTE-advanced, it encourages user equipment to select a small cell with a weakest signal as thier serving cell by adding a positive bias in cell selection process. Simulation shows that the proposed scheme results to high user association probability, while giving superior performance in average throughput compared to conventional single objective base cell selection for cell range expansion.

SWEET routing protocol is one of the many protocols developed for cluster formation and routing in wireless sensor networks. The SWEET protocol is a decentralized clustering protocol, it uses timers and interim updated cluster head estimation probability. This paper focus on the details of the initialization waiting time, sleeping mode and base station in order to increase the life cycle of the network. The initial waiting time's resizing procedure is carried by a weighting factor which is computed from the delay slot time and delay frame time. Other improvements are the introduction of sleeping mode energy saving technique. The last contribution is through the enabled base station's ability to become a cluster head. A simulation based performance evaluation of our proposed EN-SWEET protocol shows superiority in energy efficiency.

Maximum heart rate (MHR) is commonly used to estimate exercise intensity with the Karvonen formula, and there are several methods of calculating it. In this study, we used pedaling experiments on a cycle ergometer to evaluate methods of determining MHR in order to select the ones most suitable for the Karvonen formula. In the experiments, 43 subjects rode an aerobike. The results show that, for people in their 20s, two methods are suitable for estimating exercise intensity with the Karvonen formula. The main physical parameters affecting exercise intensity were also extracted, based on the experimental results.

This paper investigate the impact of primary transceivers on the outage performance of a dual-hop decode-and-forward (DF) spectrum sharing relay system with multiple secondary user (SU) destinations in Nakagami-m fading channels. To doing so, we derive new exact and asymptotic closed-form expressions for the outage probability of spectrum sharing relay systems employing the opportunistic scheduling algorithm, which readily enable us to characterize the impact of various key system parameters on the outage performance of the system. Monte Carlo simulation results are provided to verify the theoretical analysis and evaluate the effects of channel fading severity, SU relay placement, and number of SU destinations. The finding of this paper suggests that the interference temperature constraint results in the outage saturation phenomenon and zero diversity gain of spectrum sharing relay systems.

Creativity can be applied to every domain of knowledge and must be seen as an important competence. Supporting social creativity across different domains and disciplines in learning communities is an important part of collaborative process in both university education and in the context of large-scale international projects. In this paper, we present the experiences from the Virtual Summer School in Second Life as an attempt to support creative communities in a systematic manner. The Virtual Summer School acted as a forum for the presentation of innovative approaches, developments, and outcomes of research projects in the areas of technology-enhanced learning, serious games, and collaborative technologies, facilitating the exchange of ideas between students, researchers, and practitioners. To the end, we present lessons learned and implications for using this approach for supporting creative communities, outlining some recommendations and directions for future work.

We report the electronic recording of the touch contact and pressure using an active matrix pressure sensor array made of transparent zinc oxide thin-film transistors and tactile feedback display using an array of diaphragm actuators made of an interpenetrating polymer elastomer network. Digital replay, editing and manipulation of the recorded touch events were demonstrated with both spatial and temporal resolutions. Analog reproduction of the force is also shown possible using the polymer actuators, despite of the high driving voltage. The ability to record, store, edit, and replay touch information adds an additional dimension to digital technologies and extends the capabilities of modern information exchange with the potential to revolutionize physical learning, social networking, e-commerce, robotics, gaming, medical and military applications.
