Vehicular ad-hoc networks (VANETs) offer a vast number of applications without any support from fixed infrastructure. These applications forward messages in a multi-hop fashion. Designing an efficient routing protocol for all VANET applications is very hard. Hence a survey on routing protocols based on various parameters of VANET is a necessary issue in(More)
The network structures have changed significantly in the recent years. In spite of the wireless network challenges namely: changes in network topology, high error rates, power restrictions, bandwidth constraints and issues with link capacity, these networks have become popular. Researchers have contributed to a great extent to solve these challenges with(More)
In this paper, a coordination strategy for determining collision free path of end effectors of two manipulators involved in coordinated manipulation is proposed. This strategy consists of collision checking and path planning modules. Collision checking is done by modeling the links and environment of manipulator using sphere swept volume technique and(More)
The activated transcription factor ERα plays an important role in the breast development and progression of cancer. In a non-classical pathway ER interacts with other transcription factors AP-1, NFkB, SP1, etc. AP-1 transcription factors control rapid responses of mammalian cells to stimuli that impact proliferation, differentiation, and transformation.(More)
Acute and chronic alveolar or bronchial inflammation is thought to be central to the pathogenesis of many respiratory disorders. Cytokines and granulocyte macrophage colony-stimulating factors (GM-CSF) play an important role in chronic inflammation. Activator protein-1 (AP-1) the superfamily of transcription factors is involved in proliferation,(More)
Classification of iris templates based on their texture patterns is one of the most effective methods in iris recognition systems. This paper proposes a novel algorithm for automatic iris classification based on fractal dimensions of Haar wavelet transforms is presented. Fractal dimensions obtained from multiple scale features are used to characterize the(More)
Problem statement: Parallel implementation of a CBIR system for medical applications due to the rapid progress in the technologies for obtaining and storing digital images for diagnostic purposes in medicine. Approach: For feature extraction Wavelet decomposition was used for texture, global color histograms for color and novel wavelet based approach for(More)
Identifying the promoter regions play a vital role in understanding human genes. This paper presents a new cellular automata based text clustering algorithm for identifying these promoter regions in genomic DNA. Experimental results confirm the applicability of cellular automata based text clustering algorithm for identifying these regions. We also note an(More)
Steroid hormones and their nuclear receptors play a major role in the development and progression of breast cancer. MCF-7 cells are triple-positive breast cancer cells expressing estrogen receptor (ER), progesterone receptor (PR), and glucocorticoid receptor (GR). However, interaction and their role in expression pattern of activator protein (AP-1)(More)
