Photovoltaic systems normally use a maximum power point tracking (MPPT) control to continuously deliver the highest possible power to the load when variations in the insolation and temperature occur. The perturb & observe (P&O) technique, is very popular and the most commonly used in practice because of its simplicity in algorithm and the ease of implementation. But this method fails to track the power under fast varying atmospheric conditions. The proposed paper is using incremental conductance (incCond) technique intending to solve the problem of the P&O technique and the main difference of the proposed paper to the existing MPPT technique is eliminating Complexity of the incCond technique the effect of simplifying the control circuit. The resultant system is capable of tracking MPPs accurately and rapidly without steady state oscillation and also its dynamic performance is satisfactory.

In today’s relevance, the application of diesel engine holds an important role. Though the economic and environmental aspects do not support the use of diesel nowadays, it is impossible to accomplish the habitual livelihood without diesel engine. Therefore it is mandatory to devise the use of diesel in an economic and environmentally benevolent manner. In the present scenario, the combustion efficiency of compression ignition engine is very low. The improper combustion leads to poor efficiency and the emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency and thereby to increase the performance and to reduce the exhaust emission. The combustion efficiency of diesel can be further improved by reducing the ignition delay period. The present work was aimed at to improve the performance and to reduce the emission by using different chemical compounds at a definite proportion by volume with diesel, also to compare the performance and emission of the engine while using different blended fuel. For experimentation, different blended fuels in which various chemical additives blended with diesel were used as fuel. The observations were analyzed and the results were compared with the performance and emission characteristics of the engine while using diesel without any additives as fuel. The performance characteristic curves revealed that the addition of additives enhances the combustion efficiency of diesel; the outcome of the emission test concluded that there was an appreciable reduction in emission of combustion by-products.

Development of accelerator technologies capable of delivering highly stable and collimated ion beam currents, ranging from a few μA to 100 mA, and incident ion energies, ranging from 100 eV to ~10 MeV, have provided a broad and capable technology for fabrication of ICs for logic, memory, and analog operations, as well as an increasingly varied array of optical sensors and imaging devices. This paper reviews the major types of accelerators, ion sources, and scanning methods used in contemporary practice for ion implantation for electronic applications.

Organic compounds exhibit SHG efficiency which has order of magnitude largerthan widely known inorganic materials. They also offer the flexibility of molecular design and the promise of virtually an unlimited number of crystalline structures. Due to delocalization character, tailor made organic crystals can be grown which posse’s far superior properties than that of inorganic material; hence researchers focus their attention on the exploration of newer and newer organic NLO crystals. In this paper deals with the organic NLO crystals introduction, literature and currents trends.

In the research center on geographic routing, and a promising routing idea in wireless sensor networks (WSNs) is shifting in the direction of duty-cycled WSNs in which sensors are sleep scheduled to decrease energy utilization.. However, except the connected-k neighborhood (CKN) sleep scheduling algorithm and the geographic routing oriented sleep scheduling (GSS) algorithm, nearly all research work about geographic routing in duty-cycled WSNs has focused on the geographic forwarding mechanism.Sleep scheduling is a broadly used approach for reduction the energy of sensor nodes and prolonging the life span of a wireless sensor network (WSN). In this paper, we concentrate on sleep scheduling for geographic routing in obligation cycled WSNs with portable sensors furthermore, propose geographic-distance-based connected-k neighborhood (GCKN) sleep scheduling algorithm. That is GCKNF for first Scheduling calculation with multiple sinks. The approach is evaluated through simulation. Simulation results have confirmed the effectiveness of our new approach.

Electrocardiogram is one of the traditional methods used as a diagnosis mechanism for cardiac diseases which records the electrical activities of the heart. The intention of this work is to classify the ECG signal into normal and abnormal (Arrhythmia) category in an automated manner. The proposed work demonstrates an automatic classification system using the morphological features extracted from the ECG signal, and classified using effective techniques such as the Probabilistic Neural Network (PNN) and Self Organising Map (SOM) Model. MIT-BIH (Massachusetts Institute of Technology – Boston’s Beth Israel Hospital) dataset of both normal and arrhythmia patients has been used to substantiate the algorithms. The experimental results demonstrate the efficacy of the proposed method. A comparison is made for the experimental results obtained using both PNN and SOM model and the performance is studied. The SOM model has given a better performance of 97\% than PNN model during testing and both the normal and Arrhythmia categories are classified accurately.

In today’s applications, the use of diesel engine holds a key role. Even though the environmental features do not satisfy the use of diesel nowadays, it is not possible to accomplish the habitual livelihood without diesel engine. Therefore it is mandatory to devise the use of diesel in an environmentally benign way. In the present scenario, the combustion efficiency of compression ignition engine is very low. The improper combustion of fuel inside the engine leads to poor performance and emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency and thereby to increase the performance and reduce the exhaust emission. For the experimentation, blended fuels of various proportions were prepared by blending Diethyl ether as additive with diesel. The observations were analyzed and the results were compared with the performance and emission of the engine using diesel as fuel without any additives. The performance characteristic curves revealed that the addition of additives enhanced the combustion efficiency of diesel; the outcome of the emission test also revealed that there was an appreciable reduction in emission of combustion by-products.

This paper describes Tidy FS, a simple and small distributed file system that provides the abstractions necessary for data parallel computations on clusters. In recent years there has been an explosion of interest in computing using clusters of commodity, shared nothing computers.Frequently the primary I/O workload for such clusters is generated by a distributed execution engine such as Map Reduce, or Dryad, and is high-throughput, sequential, and read-mostly. Other large-scale distributed file systems have emerged to meet these workloads, notably the Google File System (GFS) and the Hadoop Distributed File System (HDFS). Tidy FS differs from these earlier systems mostly by being simpler. The system avoids complex replication protocols and read/write code paths by exploiting properties of the workload such as the absence of concurrent writes to a file by multiple clients ,and the existence of end-to-end fault tolerance in the execution engine. We describe the design of Tidy FS and report some of our experiences operating the system over the past year for a community of a few dozen users. We note some advantages that stem from the system’s simplicity and also enumerate lessons learned from our design choices that point out areas for future development.
