Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. Gathering sensed information in an energy efficient manner is critical to operate the sensor network for a long period of time. In [3] a data collection problem is defined where, in a round of communication, each(More)

In this paper we consider the problem of data collection from a sensor web consisting of N nodes, where nodes have packets of data in each round of communication that need to be gathered and fused with other nodes’ packets into one packet and transmitted to a distant base station. Nodes have power control in their wireless communications and can transmit(More)
Electron tomography is an extremely useful method for deriving three-dimensional structure from electron microscope images. The application of this technique to the reconstruction of large, complex structures such as mitochondria is described in conjunction with several tools for segmentation, measurement, classification, and visualization. In addition, the(More)
Ad hoc wireless networks and sensor networks have nodes with limited battery power, and broadcasting is an important operation in such networks. In this paper, we consider energy efficient one-to-all and all-to-all broadcast communications in such power constrained networks. It is assumed that nodes have power control and can adjust the range of their(More)
In this paper, a distance based Cluster head selection algorithm is proposed for improving the sensor network life time. This protocol achieves a good performance in terms of lifetime by balancing the energy load among all the nodes. This clustering technique help to prolong the life of wireless sensor network, especially in hostile environment where(More)
A wireless sensor network consists of large number of sensor nodes limited by a small energy spread in a large geographical area. Many algorithm collect information from the network by using clustering. LEACH is the most famous and popular one from this algorithm to maintain the energy efficiency of sensor nodes. In this paper, we propose a new algorithm to(More)
The budding process of the yeast form of Mucor rouxii was examined by electron microscopy of thin sections with particular reference to wall ontogeny. In most instances the bud wall is seen as a continuation of the inner layers of the parent cell wall. As the bud emerges it ruptures the outer layers of the parent wall. The bud wall is much thinner than the(More)
Multiple patient and economic benefits have contributed to the widespread popularity of laparoscopic surgery. Although the laparoscopic approach is safe, it is not without potential complications. The following case study describes a patient undergoing a laparoscopic salpingo-oophorectomy who had a sudden rise in end-tidal carbon dioxide to 65 mm Hg and was(More)
