introduction: in the current study we evaluated the incremental value of lateral pelvic lymphoscintigraphy imaging of endometrial or cervical cancer patients who underwent sentinel node mapping. methods: operable endometrial and cervical cancer patients without clinical or paraclinical evidence of lymph node involvement were included in the study. the day before surgery the patients were sent ...

Suppose we try to find the global minimum value of the energy function E(r), in which r ∈ R and R is the conformational space of the rotamers. The BnB algorithm executes two steps recursively. The first step is called branching, in which we split the conformational space R into two or more smaller spaces, i.e., R1, R2, . . . , Rm, where R1 ∪ R2 ∪ · · · ∪ Rm = R. If we are able to find r̂i = argm...

In wireless sensor networks (WSN), the current cluster based routing techniques may result in increased network workload, energy consumption and re-transmissions. In order to overcome these issues, in this paper, we propose an energy efficient double cluster head selection algorithm for wireless sensor network. In this technique, two cluster heads namely main and sub-ordinate cluster heads are ...

Even though there are many advancement and development in wireless sensor network, it experiences frequent wireless sensor network are battery-powered devices. Hence for lifetime of wireless sensor network energy saving is rather crucial one. The objective of the current work is sleep and wake up method in which nodes can save energy when it is sleep. When node wake up it sending or receiving d...

Cloud computing is a highly scalable and cost-effective infrastructure for running HPC, enterprise and Web applications. However rapid growth of the demand for computational power by scientific, business and webapplications has led to the creation of large-scale data centers consuming enormous amounts of electrical power. Hence, energy-efficient solutions are required to minimize their energy c...

Energy consumption is the core issue in wireless sensor networks (WSN). To generate a node energy model that can accurately reveal the energy consumption of sensor nodes is an extremely important part of protocol development, system design and performance evaluation in WSNs. In this paper, by studying component energy consumption in different node states and within state transitions, the author...

Energy efficiency is always important in wireless sensor networks. In a sensor network the nodes are present with limited energy and in each transmission nodes loss some energy. It is required to minimize the rerouting to save the energy loss. Here An algorithm for energy efficient maximally covered sensor network is presented. The initial route will be identified by the Path Selection algorith...

We observe two deficiencies of current query processing and scheduling techniques for sensor networks: (1) A query execution plan does not adapt to the hardware characteristics of sensing devices; and (2) the data communication schedule of each node is not adapt to the query workload. Both cause the time and energy waste problem in query processing. To address this problem, we propose an adapti...
