Transient Stability Enhancement of Multi Machine Power Systems using Matrix Converter Based Upfc
-V. Bharathi ; P. Lakshmanan
In present decades, owing to the swell and growing power systems electrical power demand, it is required to make exploit of the transmission lines equipped to its utmost loading limit. The transient stability restricts the steady state loading of the power system and the system becomes unstable prior attaining the state stability limit. Stability is an immense menace in the power system during the conflicts in the system. The electromechanical oscillations occurring in the rotor are generally damped out by means of power system stabilizers, which cannot damp inter area oscillations that will cause the system to lose its synchronism. Bringing back the system into synchronism is tedious and leads Flexible AC Transmission Systems (FACTS) devices, which rapidly and independently controls the actual and reactive power flows in a transmission line [1]-[5].In this paper, the enhancement of transient stability of the study system using matrix converter based UPFC employing space vector modulation technique is simulated using MATLAB – Simulink environment beneath fault condition with and without matrix converter [5]-[7]. The results obtained on both the case are compared and the efficiency of the matrix converter is revealed. Read More...

-S.Vignesh Raj ; A.Azeezur Rahman
Vehicle to grid is a new technology which is integrating huge amount of electric vehicles as modern energy storage into the electric utility grid. Plug in electric vehicles have bidirectional energy flow i.e. they can either inject power to grid or draw from it. Vehicles are charged at off peak time and they discharge their power at peak time which is acting as a spinning reserve. Thus it reduces the dependency on small expensive units , optimizing the fluctuation of the load curve and also reduces the emission. Reliability constrained unit commitment is applied to minimize the cost economically and schedule unit reserves like spinning reserves to provide system reliability. In this paper unit commitment is a master problem assigning on/off state of generating units and at the next step the sub problem solves the economic dispatch and finally the reliability issues. Reliability issues are considered as spinning reserves and the ability of the power system under study to supply loads. HPSOGSA is used to solve the unit commitment problem. Read More...

A Review Study on Air Pollutants
-Ibrahim Hussain Shah ; Mohammad Shoeb Sheikh; Bhupendra Singh
Sources of air pollution includes pollutants emitted by mobile sources like automotive vehicle, air planes, and marine ships. Many of these pollutants mainly carbon dioxide, oxides of nitrogen, sulphur dioxide etc. contribute to environmental degradation and have negative effects on human health. To protect human from health point of view and the environment, environmental regulatory agencies such as the US environmental protection agency have established policies to minimize air pollution from mobile sources. Similar agencies exist at the country level. Due to the large number of mobile sources of air pollution, and their ability to move from one location to another, mobile sources are regulated differently from stationary sources, like power plants and other industries and public in urban and semi urban areas using and combusting directly in their furnaces and cooking stoves. Instead of monitoring individual emitters, such as an individual vehicle, mobile sources are often regulated more broadly through design and fuel standards. The increase in the number of motor vehicles driven in the world has made efforts to limit mobile source pollution challenging. As a result, there have been a number of different regulatory instruments, implemented to reach the desired emissions goals. Read More...

-Rakesh Fataniya ; Rihan Maaze; Kalpesh Kapadiya
In construction industries, concrete masonry units are used commonly. Since the masonry units can be constructed with ease. Fifty billion plastic water/beverages bottles are consumed every year. The use of plastic bottles in construction materials has been around for the past twenty years, but with little focus on using full plastic bottles and PET fibers in the materials. This thesis presents the results of a study conducted to determine the compressive strength of concrete masonry units with plastic bottle cores and PET fibers. The plastic bottles were used to create the centre voids in the masonry units. Solid waste can be filled in plastic bottle for increase the compression strength of block. PET fibers used as partially replacement of fine aggregate. Concrete with 1%, 2%, 4% and 6% PET bottle fibers for fine aggregate were produced and compared against control mix with no replacement. Concrete was placed around the bottle to encase them in the masonry units. The study utilized 1000-mL plastic bottle from two different companies placed inside masonry units of 16-inch long by 8-inch wide by 8-inch high in size and analyzed the resultant compressive strength. The testing for compressive strength was determined according to the IS standard. Determination of the compressive strength of the concrete masonry units allows for further study to continue in concrete masonry units with plastic bottle cores to determine if they are viable in third world countries.

Spectrum Sensing and Mobility Management for Cognitive Radio
-Mutturaj Basavaraj Sajjan ; Mallikarjun N Deshmukh
Cognitive radio is emerging wireless technology which offers reallocation and reutilization of the unused spectrum. Not all the network runs with highest load at all the time. Therefore part of spectrum always remains unused. In a multi radio environment cognitive radio allows the user to request for spectrum from another service provider while roaming. In case the service provider has free spectrum, it can reallocate the spectrum to the demanding user. In this work we provide a mechanism for managing both intra cell as well as inter cell mobility management for efficient spectrum sensing technique. We propose a pool based spectrum management where the spectrums are managed in a group called pool such that the base stations can appropriately chose the pool depending upon network load and perform spectrum switching.

Pyrethroid Pesticide Application and Toxicity: A Review
-Mr.Randhavane Shrikant B. ; Dr.Mrs.A.K.Khambete
Pyrethroids is one of the chemical classification of pesticides with synthetic nature. Pyrethroids are also widely used as home and garden insecticides along with uses on pets and livestock, mosquito control, treatment of transport vehicles, and for treatment of ectoparasitic disease. Their desirable features provide a quick knockdown of insects at low rates, relatively low mammalian toxicity, and improved stability in outdoor environments, which has increased their marketability. Synthetic pyrethroids (SPs) are synthetic analogs and derivatives of the original pyrethrins and include a variety group of about 1,000 insecticides. Though they are analogs of pyrethrins, their production has involved extensive chemical modifications which make them highly toxic and less degradable in the environment Many pyrethroids have been linked to the disruption of the endocrine system, reproduction and sexual development, interference with the immune system and the induction of breast cancer. The widespread use of pyrethroids is a major problem as they pollute the agricultural lands and water resources and affect non-target organisms and humans. Studies showed a lot of environmental and health problems due to continuous and excessive use of synthetic pyrethroid insecticides. Paper focuses on some case studies to treat Pyrethroid wastewater.

Development of System for Automated & Secure Generation of Content (ASCGS)
-Sandeep Singh Yadav ; Mandeep Singh Yadav
Organizations find it very difficult to create content for aptitude tests by traditional methods, i.e. manual creation of a data consisting of thousands of questions, and calculating the answers to these questions. The demand for the automated system is increasing because of the reason that it takes a very lengthy time to generate the questions manually. Also we need to create answers manually so the time frame for creation of content increases only. An Automated and Secure Content Generation System (ASCGS) is a software system that provides automated creation of multiple questions from a single format. It is a system that helps in generating, and altering the questions with efficiency as per the needs. In the proposed system all the questions will be generated in automated way using randomization along with their answers, thereby reducing the human effort. The system takes an excel sheet as input which contains the language of the question along with the formula required for calculating the answer, and then it converts the every single question into multiple questions by altering their values. By the development of this system we are able to overcome the tedious work of creating content for aptitude test manually. It not only saves our time but also is efficient as the probability of an error is reduced to absolute minimal as the calculation work is done by the system and not human beings. Read More...

Efficiency of Un-Reinforced Bottle Shapped Struts in Glass Fiber Reinforced Concrete
-Rajeswara Rao Moida ; Murali Sagar Varma Sagi
An experimental investigation was carried out to determine the performance of concrete under compression and tension for different amounts of glass fibers in concrete. Fibers are added in the amounts of 0%, 0.5%, 1.0%, 1.5%, 2% and 2.5% of weight of cement. It is observed that characteristic compressive strength of concrete is increased by 10% and 14 % and split tensile strength was increased by 18% and 10 % for M25 and M40 grade concrete respectively for 1 % of fibers. As the transverse tension is the main problem in bottle-shaped struts, addition of fibers in concrete will increase the performance of bottle-shaped struts. Performance of the strut is assessed from the efficiency factor#. Test specimen consisted of 400mm X 400 mm X 100 mm panels, tested for in plane loading under compression for two different grades of concrete and different amounts fiber contents. From the test results, it was observed that efficiency of bottle shaped struts increased up to 34% and 28% for M25 and M40 grade concrete respectively for 1% fibers in cement weight. Also addition of fibers to the concrete delayed the occurrence of main crack in the bottle-shaped strut. Therefore it can be concluded that addition of glass fibers to the concrete is an economical solution to increase the performance of the concrete in terms of capacity and serviceability. Read More...

This paper addresses the application of Exhaust Gas Recirculation (EGR) for reduced oxides of nitrogen (NOx) emissions from gasoline engine. Since there hasn’t been any comprehensive review on gasoline engine using exhaust gas recirculation, this paper is made by its motivation. Prevailing and future emission norms compel engine manufacturers to incorporate techniques to reduce engine out emissions especially NOX and particulate matter NOx formation predominantly depends on high combustion temperature and literature indicates EGR is an attractive method to reduce combustion temperature. EGR temperature is an important factor while admitting higher percentage of EGR. Higher EGR temperatures caused due to increased loads limit the conduct of higher EGR ratios. EGR cooling can be advantageous when higher ratios of EGR need to be employed. The effect EGR temperature on engine thermal efficiency, NOx, smoke and HC emissions at different load conditions are discussed in this paper. NOx reductions and thermal efficiency were found to be better. Smoke and HC emissions increase for cooled EGR as compared to no EGR case. Read More...

SMART Mobile Phone for Elderly and Rural People
-Rita Puri ; Chitra Pillai
Mobile Phone plays a vital role in today’s life. It was considered as a luxury before. Over a period of time, because of rise in technology mobile phones are now considered as necessity rather than just being a luxury in a common man’s life. Previously, mobile phones were used only by the rich people and business personnel, but now every kid next door has a mobile phone in his hand. Out of' 121 crore Indians, 83.3 crore live in rural areas while 37.7 crore stay in urban areas, according to the Census of India’s 2011 Provisional population count of rural-urban distribution in the country, released by Union Home Secretary, R.K.Singh. Out of the rural population, only 38% uses cell phones. The reason behind such fewer figures is because of lack of technology knowledge and illiteracy. Even the elderly people face the problem of accessing cell phone due to lack of technology knowledge in urban area. The SMART Mobile Phone can help them to access cell phone easily without even having much technical knowledge. Read More...

A Detail Review of Optical Misalignment and Correction by Refocusing Mechanism
-Apurv J. Raval
When light rays enter in satellite telescope, it first travels to the primary mirror than reflects back towards the secondary mirror and henceforth setting a focal point after passing through the centrally provided hole on primary mirror in case of Cassegrain focus. Generally, space borne telescope are subjected to orbital loads like temperature excursion, absences of gravity, moisture release of metering structure etc. which leads to coefficient of thermal expansion and coefficient of moisture expansion of metering structure. Due to this there is the change in focal length & misalignment of optical system which ultimately reduces the quality of images. The actual location of focal point is very important for qualitative images. So to get the perfect focal point, it is necessary to reset the distance between primary and secondary mirror by means of some actuating mechanism. This distance can be corrected with the help of re-focusing mechanism & concept modification of the mechanism is discussed over here. Read More...

Performance Analysis of Bio-Diesel Produced From Blending of Premixed Pongamia Pinnata and Waste Cooking Oil
-Udaya ; Amitkumar; Prakash H R; Santhosh Poojary; Madhu H R
Energy consumption is increasing all over the world because of increasing in population, lifestyle etc. World is mainly depending on fossil fuels for the energy needs. Due to this continuous energy consumption, the fossils fuels are depleting rapidly and also producing environmental pollution. Liquid fossil fuels are the main and most frequently used energy sources for automobiles. Automobiles are using petroleum derived fuels as main fuel in their existing engines, which results in emission of greenhouse gases and other pollutants. Global warming and environmental pollution are the outcome of these emissions. The petroleum products which we are using rapidly are going to deplete within certain years. Hence there is a need to search an alternative fuel. But, considering the fact that the entire development of automobile industry is based on the use of liquid fossil fuel, it is difficult to expect a change this trend to a mass development and use of new engine constructions that would be suitable for some other type of fuel.

Finding the Sensors Location for Energy Efficient Coverage in Sensors Networks using Multi-Objective Evolutionary Algorithm
-Aditi Gupta ; Gaurav Sharma
Node positioning in the monitoring area is one of the most crucial issues in wireless sensor networks and their deployment should be cost-effective. The deployment cost depends upon the number of sensing devices deployed. Thus, optimum number of sensors should be kept in mind while optimizing the various network preliminaries like energy consumption, network coverage and connectivity. This paper proposes a sensor node deployment approach that uses multi-objective evolutionary algorithm to optimize two conflicting objectives network coverage and energy consumption while maintaining the connectivity between each sensor node and the sink node. The objectives are to completely cover monitoring area with minimum energy consumption in an efficient manner through deterministic deployment of such sensors. A simulation study is carried out to compare the performance of proposed algorithm with multi-objective territorial predator scent marking algorithm (MOTPSMA). Result shows that proposed algorithm outperforms the performance of MOTPSMA in terms of network coverage and energy consumption. Read More...

Analysis of Damping Co-Efficient on Aluminum Composites for Their Damping Characteristics using FEA
-N M Ukkali ; S B Yapalaparvi; B M Dodamani; M A Hipparagi
Effect of damping coefficient on aluminium composites like B390, AZ91D, AM60B, Al6061-T6 for their damping properties using finite Element Analysis (FEA) have been greater importance in analysis of materials. Effect of alloying for their chemical, physical & mechanical properties has been studied in this paper. Various parameters such as alloy composition, ultimate tensile stress, damping coefficient and ductility of Al alloys have been clearly analyzed. It is clear from the investigation that, there is an improvement in the mechanical properties by the addition of certain alloying elements. An attempt has been made to analyze the stress distribution (Von-Misses) using ANSYS. The results for the above alloys revealed that, the stress distribution and deformation decreases in aluminium 380 alloys with damping coefficient 0.000233. In addition, ANSYS results confirm the experimental value. Aluminum (Al) die casting alloys have a specific gravity of approximately 2.7 g/cc, placing them among the lightweight structural metals [1]. The majority of die castings produced worldwide are made from aluminum alloys. Six major elements constitute the die cast aluminum alloy system: silicon, copper, magnesium iron, manganese, and zinc. Each element affects the alloy both independently and interactively. This aluminum alloy subsection presents guideline tables for chemical composition, typical properties, and dies casting, Machining and finishing characteristics for 11 aluminum die casting alloys. This data can be used in combination with design engineering tolerance guidelines for aluminum die casting and can be compared with the guidelines for other alloys in this section aim the design engineering section. The effect of Ti and Mg on the damping behavior of in situ aluminum composites damping capacity of in situ TiB2 particulate reinforced aluminum composites with Ti and Mg excess were investigated. The composites were fabricated with an exothermic reaction process via K2TiF4 and KBF4salts. The damping behavior of materials over a temperature range of 30–300 °C was investigated by using a dynamic mechanical thermal analyzer. Experimental findings indicate that the damping capacity of composites with Ti, Mg excess, respectively is lower than that of Al/5 wt. % composite when temperature is below 180 °C and is higher than of Al/5 wt.% composite above 180 °C.

-M.Gowsalya ; M.Barathi Selvaraj
Energy measurement and billing system is not a convenient one in the traditional metering system. To calculate the bill amount in Electricity Board (EB) for the energy consumed by the consumer and to feed the value in the database is a difficult task. The aim of this idea is to use power line carrier communication for data transmission and security. The consumer can access their data about the status of the load, which is connected with the central board using PLCC. The PIC based system is used to monitor continuously and to display the status of the load connected. The PIC based smart meter sense and monitors the load connected to it. It monitors the energy consumed by each load and displays the data using LCD. This system has the advantages of doing Energy auditing in an area and to find the losses in the distribution system.

-Prabhjot Kaur Kalra ; Arvind Grewal
This research work is related to energy consumption efficiency in wireless sensor networks. Here, we have considered a weighted or Hybrid LEACH-C algorithm in the selection of Cluster Head (CH) in such a way so that its energy is used uniformly with efficient CH selection among clusters for delayed disintegration of network. LEACH-C algorithm based clustering approach has been replaced by multi-objective CH selection method where we not only considered the residual energy of nodes but the position of CH in cluster structure and distance of CH from BS. The Hybrid LEACH-C protocol has been compared with random LEACH and Max Energy LEACH or existing LEACH-C algorithm for energy equi-distribution, network life, stability and throughput. Wireless sensor network (WSN) is simulated using a MATLAB programming and power consumption algorithms take into consideration all aspects of power consumption in the operation of the node. Simulating different algorithm schemes on the same network system, same initial power sources, and routing protocol, an increase of overall system lifetime is demonstrated. The performance of hybrid LEACH-C routing protocol shows improvements in lifetime but at the cost of network stability criterion. Read More...

A Grid based LEACH-C Algorithm for Energy Efficient Routing In WSN
-Deeksha ; Jasbeer Narwal
Lifetime maximization: Energy/Power Consumption of the sensing device should be minimized and sensor nodes should be energy efficient since their limited energy resource determines their lifetime. To conserve power the node should shut off the radio power supply when not in use. We have measured performance of three algorithms in these experiments. Parameters for performance measurements are Residual Energy, Dead Nodes, Packets sent to BS. These parameters are shown in above figures and are plotted against number of rounds. If we consider residual energy and total number of rounds then LEACH-C and the grid based LEACH-C perform better than random LEACH. The residual energy at the end of total number of round shows that LEACH-C and the grid based LEACH-C most uniformly distributed energy dissipation among nodes and LEACH performs. For network integration or dead nodes criterion both algorithms perform far better than other algorithms. For number of packets sent to BS criterion the grid based LEACH-C performs better than other algorithms. Read More...
