Sufficient uptime is the main concern in a distributed system where there is no centralized organization and control. Therefore searching in P2P file sharing systems is still a big problem due to the high churn rate of nodes. To find a particular piece of data within the network P2P systems explicitly or implicitly provide a lookup mechanism, which largely depends on the availability of nodes. ...

The advent of DNA Microarray technologies has revolutionized the experimental studies of gene expressions. In the post-genomics era, clustering analysis has become a valuable tool for in-silico analysis of gene expression profiles. Although a number of clustering methods have been proposed, they are confronted with difficulties in meeting the requirements of high quality, large memory, performa...

Personalized Web Search is a best way to improve search quality by customizing search results for the users with individual information goals. This is achieved through implicitly collection of user profiles, browsing history, clicked through data, bookmarks, location of the user. However, users are not willing to expose their private preference information to search engines. Many research are u...

DOI: 10.5935/abc.20170166 Abnormal parasympathetic activity on the heart has been implicated in several forms of symptomatic bradycardia, especially in young and otherwise healthy individuals. Neurally mediated syncope, sinus arrest and advanced atrioventricular (AV) block have high risk of injury and serious implications on quality of life. Nonetheless, until recently, their clinical managemen...

Increasing demand experienced by electric utilities in many parts of the world involving developing country is a normal phenomenon. This can be due to the urbanization process of a system network, which may lead to possible voltage decay at the receiving buses if no proper offline study is conducted. Unplanned load increment can push the system to operate closes to its instability point. Variou...

As feature size is much smaller than the wavelength of illumination source of lithography equipments, resolution enhancement technology (RET) has been increasingly relied upon to minimize image distortions. In advanced process nodes, pixelated mask becomes essential for RET to achieve an acceptable resolution. In this paper, we investigate the problem of pixelated binary mask design in a partia...

( ) ( ) ( ) t gs D t r t s + − = , (1b) where the x(t) consists of a reference signal r(t), and Gaussian noise gx(t), while the s(t) consists of the time delayed version of the reference signal r(t-D), and Gaussian noise gs(t). Additionally let us assume that the noise signals are uncorrelated with each other and with the reference signal. The TOF lies at the core of many modern signalprocessin...

A genetic algorithm (GA) is a search and optimization method developed by mimicking the evolutionary principles and chromosomal processing in natural genetics. A GA begins its search with a random set of solutions usually coded in binary string structures. Every solution is assigned a tness which is directly related to the objective function of the search and optimization problem. Thereafter, t...

Draft Copy|January 24, 1996|Do not circulate. 0 abstract A exible motif search technique is presented which has two major components: 1. a generalized proole syntax serving as a motif deenition language 2. a motif search method speciically adapted to the problem of nding multiple instances of a motif in the same sequence. The new proole structure, which is the core of the generalized proole syn...
