Implementation on Peer to Peer & Client Server using XOR Metric in Cloud Computing

Peer-to-peer networks grip two and extra computers pooling person resources like disk drives, DVD players and printers. These shared resources are available to every computer in network. Each computer acts as both client & server, communicating directly within other computers. On a peer-to-peer network, for example, a printer on one computer could be used by any other computer on network. These networks are inexpensive to set up. All you need is a way to connect them, like an Ethernet cable or a Wi-Fi router

Webometric Analysis of National Library Websites of SAARC Countries

This study explored the Web Presence and Visibility of National Library Websites of SAARC Countries. Based on WISER ranking method, National library websites of SAARC countries were ranked. National Library of India secured top position in terms of Web presence. National Library of Bangladesh outscored other libraries in Webometric ranking and occupied the top position. The websites of all National libraries considered for the study lack rich files and scholarly content. Afghanistan was excluded from the study since its National library website could not be ascertained. The study recommends that Web masters should publish more content in the form of rich files and make available more scholarly content so as to improve the Web presence and visibility

Fuzzy Controlled SVC for Reactive Power Control of Long Transmission Lines

Flexible AC transmission system (FACTS) devices are used to improve the existing transmission capabilities of the transmission system by making it more flexible and independent operating. The technology is used to achieve complete deregulation of power systems i.e generation, transmission and distribution. The loading capability of transmission system can also be enhanced nearer to the thermal limits without affecting the stability. The closed loop smooth control of reactive power can be achieved by using shunt connected FACTS devices. Static VAR Compensator (SVC) is one of the shunt connected FACTS device which is to be utilized here for the purpose of reactive power compensation. This paper attempts to design and simulate the Fuzzy logic control which is used to regulate the firing angle of SVC. With this scheme, it is seen that a better, smooth and adaptive control of reactive power has been achieved. The modelling and simulations are carried out for 750km long Transmission line and the compensation is placed at the receiving end (load end). Keywords: Flexible AC transmission system (FACTS); Static VAR Compensator (SVC); Fuzzy Logic Controller (FLC)

A VALIDATED ANALYTICAL HPLC METHOD FOR THE QUANTIFICATION OF LINCOMYCIN HYDROCHLORIDE IN BULK AND SOLID DOSAGE FORM

Objective: Develop a simple isocratic reverse phase high performance liquid chromatographic method (RP-HPLC) and validate for the determination of lincomycin hydrochloride (LMH) in bulk and pharmaceutical preparations.Methods: RP-HPLC quantification was carried out by using fine pack SIL RPC18 column. The mobile phase (methanol: water) was pumped at a flow rate of 1 ml/min in the ratio of 90:10 v/v and the eluents were monitored at 254 nm.Results: The retention time of the drug was 3.73 min and produced at a linear response in the concentration range of 5-25µg/ml. The percentage RSD was found to be below 2%. The LOD and LOQ were found to be 0.854µg/ml and 0.258µg/ml respectively.Conclusion: Validation of the method was performed for precision, accuracy, linearity, ruggedness, specificity and sensitivity to conform to ICH guidelines for valuation for analytical methods

Variable frequency drive optimization using torque ripple control and self-Tuning PI controller with PSO

Drive’s output power must be restricted for the prevention of stresses over higher components in the input power system while utilizing a three-phase Variable Frequency Drive (VFD) which has powered from a single-phase AC source. To resolve this problem, we introduced a novel motor q-axis current (M-QAC) with torque ripple control (TRC) of an induction motor and self-tuning PI controller with particle swarm optimization (STP-PSO) for mitigating the stress over induction motor by the torque ripple elimination and controlling. Our proposed approach has an information related to the different parts stresses of the VFD which includes the terminal block and the diodes in the input side, DC bus capacitors, torque ripple, harmonics in the current and active performance for sudden changes in the speed and load. Our proposed model is simulated in MATLAB/Simulink environment. In this  paper the standard dc-bus voltage ripple-based fold- back, q-axis average current fold-back and q-axis ripple current fold-back methods are utilized for the comparative analysis. Also the comparative analysis of proposed M-QAC, TRC and STP-PSO methodologies are provide with respect to steady-state values of peak-to-peak dc voltage (Vdc), peak-to-peak input current (IINPUT), input RMS current (IRMS), motor speed and the output power. Extensive simulated performance show that the STP-PSO obtained superior results over conventional standard dc-bus voltage ripple-based fold-back method, M-QAC and TRC schemes

Cost analysis of antiepileptic drugs available in India

Background: Epilepsy is one of the major causes of morbidity, mortality and needs long-term treatment. There is a wide range of variation in the prices of drugs marketed in India. Thus, a study was planned to analyse out cost variations of antiepileptic drugs available in Indian market.Methods: Minimum and maximum costs in rupees (INR) of antiepileptic agents manufactured by different companies, in the same strength and dosage forms were obtained from “current index of medical specialties” January ‑ April 2016. The cost ratio and percentage cost variation were calculated for each generic antiepileptic agent.Results: There is a wide variation in the prices of different brands of same antiepileptic agent in Indian market. The highest cost ratio and percent cost variation was found for divalproex 500 mg [(1:3.17) and 216.7], followed by lamotrigine 25 mg [(1:2.5) and 150], clobazam 10 mg [(1:2.47) and 147.3] and clonazepam 0.5 mg [(1:2.46) and 145.9].Conclusions: The average percentage price variation of different brands of the same oral antiepileptic drugs in Indian market is very wide. Treatment of epilepsy has a long course with compliance being a key factor for successful treatment. Improved adherence to the treatment can be ensured by decreasing the cost of therapy, by changes in the government policies and regulations and creating awareness among treating physicians for switching to cost effective therapy

Overview of the Fish Diversity of Indian Waters

Fishing is one of the oldest human activities and it developed gradually, when our ancestors moved from the collection of plants and animals to hunting by using tools and weapons. The oldest fishing implements so far identified are harpoons, found in the territory of Congo, and dating about 90,000 years. Interestingly, these harpoons were found associated with the bones of a species of now extinct giant catfish. In India too, it is believed that the development of fishing must have been parallel. There are reports that fishes were grown in reservoirs as early as 320 BC. There are several evidences of fish capture and culture since then. There were evidences to indicate over-fishing in the River Ganges as early as 1785. Russell made the first systematic study of the Indian fish fauna from 1785 to 1789 AD. Sir Francis Day studied the systematics of Indian fishes for over 20 years and listed 351 genera and 1418 species of marine, brackish water and freshwater fishes in 1868. Later, Alcock added 86 new genera and 200 species to the list. Jones and Kumaran (1980) recorded 603 species of fish from the Laccadive archipelago. Of the 603 species of marine fishes belonging to 126 families that are reported from the islands, at least 300 species belong to the ornamental fish category. At present, of the recorded 24,000 species of finfishes in the world, about 2364 species are known to occur in India (www. fishbase. org). Rao (2009) recorded 1371 species in 77 families from the Andaman and Nicobar islands
