Optimisation in wireless sensor networks is necessary due to the resource constraints of individual devices, bandwidth limits of the communication channel, relatively high probably of sensor failure, and the requirement constraints of the deployed applications in potently highly volatile environments. This paper presents BioANS, a protocol designed to optimise a wireless sensor network for reso...

We motivate, formalize and investigate the notions of data quality assessment and data quality query answering as context dependent activities. Contexts for the assessment and usage of a data source at hand are modeled as collections of external databases, that can be materialized or virtual, and mappings within the collections and with the data source at hand. In this way, the context becomes ...

abstract background and aims: one of the complications of breast cancer treatment is ipsilateral upper extremity lymphedema. secondary lymphedema is a chronic condition that leads to loss of function and disorder of quality of life. the aim of this study was to evaluate the effects of complex decongestive physical therapy (cdp) on pain severity and quality of life in patients with secondary upp...

IEEE 802.16/WiMAX is the network which is designed with quality of service in mind. In this paper the authors have made an attempt to qualitatively analyse the performance factors at the physical layer of mobile WiMAX for Rayleigh and Rician channels using different modulation techniques. The comparison of quality of service parameters like BER and power spectral density between different chann...

Given that Peighambarieh street in the historical context And valuable Qazvin, Which has historical and cultural, But it seems This street appeared during the time period until today, There were many inconsistencies, Therefore, it is necessary that this study, considering all the physical and non-cellular factors affecting the range, Provide solutions for it. Research Objectives include: 1- Rec...

With the upcoming widespread availability of sensors, more and more applications depend on physical phenomena. Up-to-date real world information is embedded into business processes, in production environments, or in mobile applications, so that such context-aware applications can adapt their behavior to the current situation of their user or environment. For this, a high variety of so-called co...
