Power quality is one of major concerns in the present era. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. A dynamic voltage restorer (DVR) based on photovoltaic (PV) generation/battery units is proposed to improve voltage quality in a micro-grid. The restorer is connected with the grid by a rectifier, which is in series with the point of common coupling (PCC). Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure of end use equipments. One of the major problems dealt here is the voltage sag. To solve this problem, custom power devices are used. One of those devices is the Dynamic Voltage Restorer (DVR), which is the most efficient and effective modern custom power device used in power distribution networks. Its appeal includes lower cost, smaller size, and its fast dynamic response to the disturbance. This paper introduces power quality problems and overview of Dynamic Voltage Restorer so that young electrical engineers come to know about such a modern custom power device for power quality improvement in future era.

Renewable energy resources have astonishing capabilities to fulfill ever increasing future demands if utilized properly. Changing climatic conditions is a major inherent drawback associated with it and MPPT (Maximum Power Point Tracking) is one of the techniques used to overcome it (wind and solar). This paper has proposed a negative output super lift Luo converter which is integrated with multiple sources for reducing passive elements. The proposed MISO (Multiple Input Single Output) topology can be used for low or high power applications and can be extended to interface any number of sources having different characteristics. In case used for renewable sources' grid integration, it can extract maximum power from each source with its own MPPT controller. It also has a bidirectional battery storage port that improves reliability of the system. These systems are simulated in MATLAB software environment and results are obtained.

Information technology generated huge data on the internet. Initially this data is mainly in English language so majority of data mining research work is on the English text documents. As the internet usage increased, data in other languages like Marathi, Tamil, Telugu and Punjabi etc. increased on the internet. This paper presents the retrieval system for Marathi language documents based on the user profile. User profile considers the user's interests, user's browsing history. The system shows the Marathi documents to the end user based on the user profile. Automatic text categorization is useful in better management and retrieval of these text documents and also makes document retrieval as simple task. This paper discusses the automatic text categorization of Marathi documents and literature survey of the related work done in automatic text categorization of Marathi documents. Various learning techniques exist for the classification of text documents like Naïve Bayes, Support Vector Machine and Decision Trees etc. There are different clustering techniques used for text categorization like Label Induction Grouping Algorithm, Suffix Tree Clustering, and K- means etc. Literature survey shows that for non-English documents VSM [Vector Space Model] gives the better results than any other models. The system provides text categorization of Marathi documents by using the LINGO [Label Induction Grouping] algorithm. LINGO is based on the VSM [Vector Space Model]. The system uses the dataset which contains 200 documents of 20 different categories. The result represents that for Marathi text documents LINGO clustering algorithm is efficient.

MapReduce framework is suitable for dataintensive applications for large scale processing, but these classes of applications like machine learning algorithms, graph algorithms, sentiment analysis algorithms, etc. have dealt with skewness, diversity of data to adapt changes in real time. For example, it is difficult to adapt to real time changes in training data/corpus for big data applications like Sentiment Analysis, Email spam detection, and log file analysis. To achieve this goal, we have proposed an algorithm that is based on concepts of functional programming and self-adjusting computations that supports effectively accepting changes for system ranging from making training set/ language corpus domain-specific, amortized analysis of algorithm to change in storage, network and architecture design for distributed systems. For experimental purposes, we have implemented Selfie, self -adjusting algorithm with Splay tree for Twitter Sentiment analysis, which makes system responsible for skewness in access pattern and diversity in trends. Proposed algorithm can be helpful for other iterative and interactive applications that faces machine learning challenges like feature generation and selection, over-fitting, explain and improve models to effectively deal with large dynamic data sets.

Now a days, the number of Internet and wireless communications users has rapidly grown and that increases demand for security measures to protect user data transmitted over openchannels. Cryptographic algorithms are very essential for security of the systems worldwide. In December 2001, the National Institute of Standards and Technology (NIST) of the United States selected the Rijndael algorithm as the suitable Advanced Encryption Standard (AES) to replace the Data Encryption Standard (DES) algorithm. AES can be considered the most widely used modern symmetric key encryption standard. The AES algorithm is a block cipher that can encrypt and decrypt digital information. This paper explores task level parallelism with three concurrently working AES modules to achieve less area and high throughput. With the area optimization techniques, the system becomes area and time efficient as the throughput of 5.751Gbps is achieved with less area. The design is implemented in Zynq(xc7z020-2clg484) device and tested on Zedboard. As three different implementations of AES are explored, the design has three times higher throughput with less area than the other systems. To encrypt/decrypt a file using the AES algorithm, the file must undergo a set of complex computational steps. Therefore a software implementation of AES algorithm would be slow and consume large amount of time to complete. The immense increase of both stored and transferred data in the recent years had made this problem even more serious when the need to encrypt/decrypt such data arises.

Because of combustion of fossil fuels global warming caused by environmental problems, the raising prices of crude oils and natural gases. They promote continuous effort to improve energy system and its efficiency. There is a need to search for abundant and clean energy sources due to the depleted and increasing prices of oil. Solar energy acts as an alternative renewable energy source. Photovoltaic cells are used as renewable energy system. Photovoltaic (PV) cells can be used to generate dc voltages and given to DC-DC converter. DC-DC converter used is Buck boost type of converter. The converter output is given to battery to inverter and load. Buck boost converter gives constant output which will controlled by PWM controller and feedback control system. Feedback control system has compensation network with different types and parameters. Designing of converter gives constant output. A maximum power point tracking (MPPT) algorithm technique is needed to track the peak power to maximize the produced energy. The maximum power point in the power voltage graph is identified by an algorithm called as incremental conductance method. This algorithm will identify the suitable duty cycle ratio in which buck boost converter should operate to maximum point. The MPPT algorithm is vital in increasing the efficiency of the system. This output is given to battery though the H bridge inverter circuit. The ac output voltage is directly fed to low voltage grid though the PLL circuit. The control of PWM for converter, inverter, MPPT algorithm and PLL is controlled by using MICROCHIP dsPIC30F4011 DSP processor. The total experimentation is carried out and results of converter, inverter, grid control and MPPT characteristics are analyzed.

A Cascode differential LNA using 130nm CMOS process is proposed. The linearity enhancement is achieved by, restrained generation of 3rd order Harmonic component. To cancel the 3rd Harmonic component, a RC feedback from Drain node of common-gate to the Source node of common-gate transistor is used. To achieve low Noise Figure, Cascode stage transistors are used. This technique is verified by comparing the design of Classical LNA and the Proposed LNA. The LNA achieves Noise Figure 2.435dB, Input-referred P1dB -4.18dBm and Gain 19dB. From these measured result the Proposed LNA successfully proves that it has minimum Noise Figure and is linear.

Strict environmental regulations and continuously increasing electricity demand have resulted in interest for the utilization of renewable energy sources. This paper investigates the feasibility of a stand-alone hybrid energy system to meet out electric load requirements of JK Lakshmipat University, Jaipur. In order to maintain continuity of electricity supply, a single energy source is not a good option. So, we have considered a hybrid system having wind turbines, solar PV system, and diesel generator with the integration of battery bank. Load scenarios for both summer and winter season have been considered for modeling of proposed hybrid energy system. Techno-economic analysis for proposed system model has been performed using HOMER software. Variation in load for a month and a year are considered as 10% and 20% respectively. The cost of energy is coming out to be 0.462 $/kWhr, which is quite comparable with contemporary hybrid renewable energy technologies. As university has two diesel generators of 600 KVA and 250 KVA, but HOMER software suggested 250 KVA generators only, which will also help to reduce emission level significantly.

Renewable power plant has more advantageous over conventional power plant. Specifically, Solar energy is available everywhere, free of cost but challenge is to extract maximum power from the available energy. Solar cell is a non-linear source of electrical energy, hence various algorithms like Perturb & Observe, Incremental Conductance etc. are implemented using DC-DC converter to extract maximum power from it. These algorithms create oscillations in output. The proposed algorithm takes feedback of irradiance of sunlight and temperature to avoid oscillations. Internal resistance of the solar panel is depends on factors like temperature, irradiance etc. At a particular instant, internal resistance of solar panel is calculated by sensing irradiance and temperature values from sensor. On that operating condition, all dependent parameters of solar panel are calculated and internal resistance of solar panel is calculated. DC-DC converter transfers the load resistance to its input depending upon its duty cycle. The proposed control strategy will set the duty cycle of converter so as to match transferred load resistance with internal resistance of solar panel. Hence by the maximum power transfer theorem, maximum power will extracts from the solar panel when transferred load resistance is equal to the internal resistance. This condition is achieved by this proposed maximum power point tracking (MPPT) algorithm. Control System is continuously monitoring irradiance and temperature, if there is change in it then only it will try to track MPPT. This paper discusses about the design, simulation and practical implementation of MPPT algorithm using DC-DC Converter.

Energy auditing is an integral part of energy conservation and energy management is also part of conservation. It is an initial study in establishing an energy management programme. This paper reviews the initial attempts to understand the energy consumption patterns in a residential building and to reduce the energy consumptions. A case study is included to investigate the reduction in energy consumption per unit in order to make building energy efficient. A feasibility study is done to check the increase in construction cost to gain energy efficiency credits for LEED certification. Payback calculations are done to understand the Investments required and hence feasibility is confirmed.
