the telecom services have been recognized the world-over as an important tool for socioeconomic development for a nation and hence telecom infrastructure is treated as a crucial factor to realize the socio-economic objectives in india. accordingly, the department of telecom has been formulating developmental policies for the accelerated growth of the telecommunication services.  bsnl is a wholl...

BACKGROUND There is overwhelming evidence of the benefits of physical activity and the physical environment is increasingly recognized as a promising determinant of physical activity participation. The influence of the environment on physical activity has not been evaluated among black Africans and no specific measure exists for assessing environmental factors related to physical activity in an...

This paper describes the trends of Web service technologies that support ‘Dynamic Collaboration.’ For the realization of collaboration in business, five important features are shown: (1) connectivity and interoperability, (2) security and safety, (3) robustness and reliability, (4) dynamism, and (5) contract. There are various specifications proposed on Web services and ebXML, which is a comple...

To overcome the problems of coverage blind areas and redundancy when sensor nodes are deployed randomly in heterogeneous wireless networks (HWSNs). An optimal method for HWSNs based on an improved social spider optimization (SSO) algorithm is proposed, which can reduce energy consumption improve network coverage. First, a mathematical model HWSN established, complex combinatorial problem. globa...

The authors evaluated a site-independent telemedicine system. Telemedicine may be limited by the need for fixed connectivity. Wireless and site-independent technologies eliminate this limitation. Twenty-five stroke patients underwent evaluations by remote and bedside examiners. Ten of 15 (67%) NIH Stroke Scale and 9 of 11 (82%) Modified NIH Stroke Scale items showed excellent interrater reliabi...

We extend the network reliability estimation methodology based on evolution (creation) Monte Carlo into four directions: (i) introducing unreliable nodes; (ii) adjusting the evolution process with merging to "closure" operation suitable for unreliable nodes; (iii) in case of numerical instability in computing convolutions, we suggest a special Monte Carlo algorithm based on importance sampling;...

Introduction: Neighborhood tractography offers the potential to improve the reliability and reproducibility of automated white matter pathway extraction and associated measurements of connectivity and tract integrity. Neighborhood tractography frameworks have been proposed for local tractography methods, particularly those based on streamline, or probabilistic streamline algorithms [1,2]. In th...
