Abstract

Wind energy is one of the world’s fastest growing energy technologies. It is estimated that 16% of the world’s electricity will be harnessed from wind power by 2020. There are many loads (such as remote villages, islands, ships etc) that are away from the main grid. They require stand-alone generator system (which can provide constant nominal voltage and frequency) to provide for their local electrification. This requirement has lead to widespread research on development of new technologies for stand-alone generators. So this paper discuss about the recent research on Wind Energy Conversion System, the advancement of wind energy conversion system is permanent magnet synchronous generator based wind energy conversion system. PMSG based WECS have higher efficiency than other generator based wind energy conversion system. In this system, there are no requirements of gear box. Permanent Magnet Synchronous Generator excited by permanent magnet.

Abstract

This work focuses on the nonlinear dynamics of fixed-free cantilever beam under electrostatic actuation. Electro statically actuated micro devices experience a fundamental limit on their stable travel range due to a phenomenon called as the pull-in Instability. Accurate evaluation of the pull-in voltages is vital in the design of electro statically actuated MEMS devices. The design simulations of MEMS based micro-cantilever made up of single crystal silicon using FEM (COVENTERWARE) is done. The design of the cantilever structure have been optimized with finite element method based simulation in COVENTERWARE platform.

Abstract

Landslide is a physical phenomenon in which large amount of rock debris break or slide down the slope leading to destruction of large natural as well as material losses along with lives of many people. Massive losses are caused by landslides in different parts of world. In India landslide is popular phenomena of Himalayan region and southern Nilgiri Mountains. Such losses could be avoided if proper intelligence system is present which could inform about the event in advance or at least give information about landslide trigger factors like water content in soil, tectonic activity, disturbance frequency of anthropogenic activates, litho logy and various others. In this paper different landslide detection techniques are discussed.

Abstract

Radars are primarily used to detect and identify moving objects, so the multi-axis drive system is one of the most important parts that directly affect the quality and versatility of the radar station. In the problem of control of the two axes of the radar station, we always need to consider many things at the same time such as variable dynamic parameters, the movement of one axis affected by the other, the requirement for accurate traction, the need for wave interference. An adaptive robust control designed to satify the quality requirement, with flexible structure which reduces the amount of computation is proposed in this paper.

Abstract

The computerise electronic identification system is a system design to enable us assign electronic identification code to every staff and student for effective monitoring and management of staff and students by the institutions. This process was achieved by using a passive card (MIFARE, ISO 14443 A) for the identity card and a Total Wireless Reader (TWR PRO) as the RFID reader. The Microsoft Visual Studio 2012 was use to develop the Graphic User Interface environment (GUI). The C# programming language was used to implement the system and the .NET frame work 4.5 is used for the frame work. The Microsoft access database was used because of its portability The database was created by entering the individual data into the system and this information was used to generate electronic Id which was encoded in the chip contained in the passive card by placing the card close to the Rfid device. The accuracy of the system was tested by selecting 36 students with their passive identity cards and ask them to go into the classroom were the Rfid have been set up and the system was able to read the cards and generate report within five minutes.

Abstract

Oil/Gas offshore extraction involves long feeders being used to supply power to Induction motors. Modeling previously was done ignoring effects of long feeders and line parameters. We design a model considering Long feeder effects and use of inverter output filters. We considered Field oriented control technique. Due to subsea applications we implement control technique at stator side itself. Stator values are measured and then transformed from three phase to 2 phase values using Clarke transform blocks. Long feeder is modelled as a π-model equivalent considering lump parameters.LC filter is used at inverter output to improve output response. Transformed values are fed to the designed controller which again feeds signal to inverter via SVPWM. Simulation and experiments show that model can be effectively controlled from stator side, LC filter helps to obtain a near sinusoidal output response and also helps to reduce harmonics and dv/dt rising of output voltage.

Abstract

In current days, image processing techniques are widely used in many medical areas for improving earlier detection and treatment stages, especially in various cancer nodules such as the lung cancer, breast cancer, brain cancer and so on. This paper shows the detection and classification of lung cancer stages based on CT Scan Images. The median filter algorithm is used for image processing. In this paper, morphological operations are used to detect lung cancer nodule. And then, extracts low-level features from the detected nodule. This paper uses seven features area, perimeter, eccentricity and four texture features using Gray-level Co-occurrence Matrix (GLCM). Finally, the extracted features from the detected regions are given as input to 3-layer Artificial Neural Network (ANN) classifier to classify the detected lung cancer nodule into stages. Diagnosis is mostly based on CT (computed tomography) images. The lung cancer CT scan images for each stage obtain from the internet.

Abstract

A new methodology is developed for addressing the optimal DG placement problem (OPDG) in practical distribution system. The method takes all the possible load models and their combination. Using load clustering, load flow results are presented taking exponential models of each individual load model into account. This method closely resembles any practical distribution system and the analysis can be extended to real time case studies also. In this scenario, the optimal DG placement is considered by taking minimum voltage as a criteria for DG placement and sizing was determined by using PSO for total real power loss minimization. The proposed method was applied on standard IEEE 69 bus system and the results were demonstrated. The results demonstrate that besides the total real power loss minimization, incorporating DG also improved voltage profile and reduced reactive power loss also.

Abstract

This paper analyzes and forecasts of carbon dioxide (CO2 ) emissions, renewable energy consumption, and gross domestic product (GDP) for Vietnam during the period of 2010 to 2019. These three variables are important factors that affect the energy efficiency, economic growth as well as climate change in Vietnam. Thus, this paper employs the grey prediction models including GM (1,1) and DGM (1,1) to predict three variables. According to forecasting results, the CO2 emissions of Vietnam will grow by 3 %, the renewable energy consumption is not increase significantly, and the GDP is forecasted to increase 5% in 2019 compared with 2010. The study provides policy makers with useful information in finding the solutions to improve energy efficiency, economic growth and environmental protection in Vietnam.

Abstract

This paper introduces the nondestructive prediction of the concentration in trace elements of the quail Coturnix coturnix eggs by color image processing. First, the evaluation of zinc, chrome and magnesium elements of quail eggs was done by atomic absorption spectroscopy. Secondly, algorithms for the determination of the color co-occurrence matrix and Haralick attributes extraction were implemented. Then, eggs were classified according to these attributes and their concentration in trace elements.The obtained results showed that quail Coturnix coturnix eggs are grouped in three distinct classes. They have been determined by evaluating the aspect of the eggshell (Haralick attributes) to deduce the concentration in trace elements of the egg. The attributes f5 (homogeneity), f7 (variance of sums), and f12 (correlation information) are respectively strongly correlated to the zinc, chrome and the magnesium concentrations. Eggs with different shells have shown a different composition in trace elements.
