This paper presents a new cluster-based power preservation scheme. Our clustering strategy for power saving is defined based on the “similarity of data” coming out from the sensors. The proposed clustering works in conjunction with our learning algorithm to obtain an optimum sleeping time of the sensors without disrupting the monitoring activity. The algorithm helps to effectively regulate the ...

From the standpoint of Neoliberal Institutionalism, this study explores Malaysia's participation in activities that make energy topic and/or object foreign policies, whether through bilateral or multilateral engagements. This research, which aims to evaluate relevance economy and diplomacy explain reason for its involvement these cooperations, is necessary because growing global market. Informa...

The rate of skeletal muscle anaerobic A TP resynthesis is rapid when compared with aerobic resynthesis, however a high rate of anaerobic resynthesis can only be maintained for short periods of time. Table 1 shows the rates of A TP resynthesis from phosphocreatine (pCr) and glycolysis during 30s of near maximal isometrie contraction in man. Af ter only 1.3s of contraction the rate of PCr utilisa...

The paper describes a scheme for the implementation of low power cores for hearing aid applications. Power saving features of the scheme are two fold. The first due to the utilisation of a macro-component framework which allows the rapid assembly of the cores on easy-to-verify hierarchical plug-in basis. The second is due to the system-on-chip strategy. The cores are embedded within an ARM-base...

Cooperative diversity is a powerful tool that can be used to improve the performance of wireless networks. The use of directional antennas has also shown to offer an effective way for efficient bandwidth utilisation. In this study, the authors investigate the effect of both the transmission power and the number of cooperative relays on the maximum achievable throughput in energy-constrained coo...

Basing on results of previous studies, the efficiency of a Brayton/Hirn combined cycle, fuelled with a clean syngas produced by means of biomass gasification and equipped with CO2 removal by chemical absorption, resulted 33.94%, considering also the separated CO2 compression process. The specific CO2 emission of the power plant was 178 kg/MWh. In comparison with values previously found for an I...

BACKGROUND Immigrant elderly are a rapidly growing group in Dutch society; little is known about their health care use. This study assesses whether ethnic disparities in health care use exist and how they can be explained. Applying an established health care access model as explanatory factors, we tested health and socio-economic status, and in view of our research population we added an accult...

Wireless sensor networks (WSNs) provide a means to acquire lots of raw data from vast amounts of easy-to-deploy sensors. Ontologies facilitate structuring data into information and support automatic inference mechanisms. The combination of wireless sensor networks and ontologies can bring significant added value to intelligently process the raw data intomeaningful information. In an ontology-ba...

CO2 utilisation technologies—also called carbon dioxide utilisation (CDU) and carbon capture and utilisation (CCU)—convert CO2 via physical, chemical, or biological processes into carbon-based products. CO2 utilisation technologies are viewed as a means of helping to address climate change and broadening the raw material base for commodities that can be sold to generate economic revenue. Howeve...

INTRODUCTION A large private operating theatre complex was investigated to address the lack of published South African benchmarks for utilisation. All major theatres were staffed during normal working hours (07h00 - 19h00), emergency cases being provided for on an ad hoc basis through spare capacity. METHODS An extensive billing database, amounting to 28 991 records of procedures performed du...
