The Peer-to-Peer (P2P) computing systems are based on desktop computers (PCs) exists at the edge of Internet. This type of frameworks contains several thousands of computing nodes which spread all over the world and need to be organized. To achieve decentralization the P2P computing architectures classify the peers into different groups based on different peer properties. In order to improve the reliability, scalability, and performance of decentralized P2P computing systems efficient peer grouping strategy is required. Here we proposed an algorithm to identify the reliable peer groups in P2P computing systems by using the peer properties like peer availability, credibility and computation time. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.

The observed frequency dependent optical response of alkali.metal-doped fulleride superconductors (Tc ≈ 19 K) has been theoretically analysed. The calculations of the optical conductivity, σ(ω), have been made within the two-component schemes: one is the coherent Drude carriers (electrons) responsible for superconductivity and the other is incoherent motion of carriers from one atom to other atom of C60 molecule to a pairing between Drude carriers. The approach accounts for the anomalies reported (frequency dependence of optical conductivity) in the optical measurements for the normal state. The model has only one free parameter, the relaxation rate. The frequency dependent relaxation rates are expressed in terms of memory functions. The coherent Drude carriers form a sharp peak at zero frequency and a long tail at higher frequencies, i.e. in the infrared region. However, the hopping of carriers from one atom to the other (incoherent motion of doped electrons) yields a peak value in the optical conductivity centred at mid-infrared region. It is found that both the Drude and hopping carriers will contribute to the optical process of conduction in the K3C 60 and shows similar results on optical conductivity in the mid-infrared as well as infrared frequency regions as those revealed from experiments. © Indian Academy of Sciences.

Web Architectures are generally designed with particular functional and nonfunctional requirements. Organizations often need to choose Software Architecture for future development from several competing candidate architectures. There are several stakeholders such as client, manager, architect, developers etc, involved in software architecture life cycle. For every stakeholder their own requirements are there in terms of quality attributes. To choose any web architecture, it is very difficult task to identify which is better. Existing system have some limitations. In this paper, we have taken three web architectures Client-server web architecture (CWA), Distributed web architecture (DWA), Service-oriented architecture (SOA). With mathematical approach, according to requirement we are going to select the suitable web architecture from CWA, DWA and SOA. It means that the process software architecture have some scenario in term of quality attribute. In this paper we have used the return of investments (ROI)for test the cost of the web architecture. © 2015 IEEE. Source

Health depiction and image are indispensable for patient instruction and self-care. Images characterize an imperative feature of the entire medical knowledge. Presently there is hardly any attempt in automatically construction inclusive image bases for universal health information customers. We proposed an approach to automatically construct a consumer -leaning image library contain images of individual organs, diseases, drugs and other medical entities. Health check imaging has become an important tool not simply in document patient presentation and clinical findings, but also considerate and managing various diseases. Image data present tangible visual evidence of disease manifestation. The number of digital images that needs to be acquired, analyzed, classified, stored and retrieved in the medical centers is exponentially growing with the advances in medical imaging technology. The goal of this work we proposed medical image retrieval technique for pathology images that implements recent improvements in feature representation, efficient indexing, and similarity matching. © 2014 IEEE.
