The continuously self-configuring, Infrastructure less Mobile Ad-hoc Networks (MANETs) route in effective manner by utilizing the voluntary cooperating nodes. That is the ability of each node to move independently and freely, thus can configure the links to other nodes frequently. Certain node refuse to cooperate and leads to the selfish behavior and such nodes are named as selfish nodes, whose...

background the occupational health is an important issue. in some jobs, the working conditions contribute to musculoskeletal complaints and the overall health of the individual is compromised. musculoskeletal complaints have gained credence in the public as one of the most important problems in the field of occupational diseases. physical and mental health of crew members with critical jobs and...

introduction:  the  success  of  hyperthermia  depends  on  the  accuracy  of  the  temperature  monitoring in the tumor and the surrounding normal tissue. in this study, the temperature changes  were determined by computing the speckle displacement in the ultrasound digital images. speckle  tracking algorithm was used to compute the displacement.  materials and methods: the experiment was perf...

cyphomandra betacea (cav.) is a native species from south america that is cultivated because its fruits have a high content of vitamins. in colombia, it is common to find periods of drought between the rainy seasons or during enso events such as el niño. an adequate nutritional status of k+ in plants helps to increase the chance of tolerating the negative effects of drought stress. regarding th...

The Networks of vehicles moving on the road are considered as Vehicular Ad Hoc Networks (VANETs). The relative speed of the vehicles may be up to 300 km/hr and the number of nodes is very high. In Vehicular Ad Hoc Networks (VANETs) the nodes movement is bounded to road topology. In VANET the link breakage can be avoided with the help of the mobility pattern knowledge for neighbor nodes. In this...

In a resource limited multi-agent system, it is of practical importance to select a fraction of nodes (agents) to provide control inputs such that consensus can be achieved with optimized performance in terms of network cost and/or convergence speed. In this paper, we investigate the problem of how to select control nodes so as to minimize the network cost, where the control nodes are selected ...

We present a model of a mobile ad-hoc network in which nodes can move arbitrarily on the plane with some bounded speed. We show that without any assumption on some topological stability, it is impossible to solve the geocast problem despite connectivity and no matter how slowly the nodes move. Even if each node maintains a stable connection with each of its neighbours for some period of time, i...

In this channel,we study rate region of a Gaussian two-way diamond channel which operates in half-duplex mode. In this channel, two transceiver (TR) nodes exchange their messages with the help of two relay nodes. We consider a special case of the Gaussian two-way diamond channels which is called Compute-and-Forward Multiple Access Channel (CF-MAC). In the CF-MAC, the TR nodes transmit their mes...
