The IEEE has standardized the 802.11 protocol for Wireless Local Area Networks. The primary medium access control (MAC) technique of 802.11 is called distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance (CSM A/CA) scheme with binary exponential backoff algorithm (BEB). DCF describes two techniques to(More)
Rho GTPases are key regulators of the actin-based cytoskeleton; Rab GTPases are key regulators of membrane traffic. We report here that the atypical Rho GTPase family member, RhoBTB3, binds directly to Rab9 GTPase and functions with Rab9 in protein transport from endosomes to the trans Golgi network. Gene replacement experiments show that RhoBTB3 function(More)
A multi-site, time-resolved fluorescence resonance energy transfer methodology has been used to study structural heterogeneity in a late folding intermediate ensemble, IL, of the small protein barstar. Four different intra-molecular distances have been measured within the structural components of IL. The IL ensemble is shown to consist of different(More)
Semantic Web is a Web that adds more meaning to the Web documents in order to access knowledge instead of unstructured material and also allowing knowledge to be processed automatically. One of the methods to achieve this is of using Ontology. The Ontology defines the terms and the relations among the terms on a domain. There are number of Ontology(More)
Breast cancer remains as a leading cause of cancer deaths among women in many parts of the world. Cancer is an abnormal, continual multiplying of cells. Most types of cancer cells eventually form a lump or mass called a tumor. In this paper, an automatic CADe system for mammographic mass detection that uses complex texture features is employed. The presence(More)
Retrieving the most relevant information for the Web becomes difficult because of the huge amount of documents available in various formats. It is mandatory for the users to go through the long list of snippets and to choose their relevant one, which is a time consuming process. User satisfaction is secondary in this aspect. One approach to satisfy the(More)
Pulse compression is a technique that plays an important role in various fields like radar, sonar and spread spectrum communication to achieve the high transmit energy of a long pulse while preserving the range resolution of a short pulse. In this paper a new method of design of mismatched filter to minimize the Peak sidelobe ratio (PSLR) in the pulse(More)
Evidently there is a tremendous increase in the amount of information found today on the largest shared information source, the World Wide Web. The process of finding relevant information on the web is overwhelming. Even with the presence of today's search engines that index the web it is difficult to wade through the large number of returned documents in a(More)
