Improvement of Voltage Quality of Micro Turbine Generator With Matrix Converter & Venturini Technique's
Improvement of Voltage Quality of Micro Turbine Generator With Matrix Converter & Venturini Technique's
Abstract: In recent years, application of Distributed Generation (DG) sources has increased significantly. Micro turbine-Generator (MTG) is well suitable for different distributed generation applications, because it can be connected in parallel to serve larger loads, can provide reliable power and has low-emission. The main characteristics of MTG can be summarized in low maintenance, capacity of operation with liquid and gas fuels (including natural gas) and small area required for installation [1]. MTGs have the rated power from 30 to 250 kW, generating electricity in ac, and they can be installed in isolated conditions or synchronized with the electrical utility.MTGs are available as single-shaft or split-shaft units. Single-shaft unit is a high-speed synchronous machine with the compressor and turbine mounted on the same shaft. While, the split-shaft design uses a power turbine rotating at 3000 rpm and a conventional generator connected via a synchronous generator-PMSG), frequency converters (interface converters), and protection and control systems (Fig. 1)[1] . The interface converter is used to convert PMSG output voltage frequency (high frequency) to power system (50/60 Hz) frequency.

Prototypic Gps-Gsm Integration for Enhancing Public Transportation and Management Services.
Prototypic Gps-Gsm Integration for Enhancing Public Transportation and Management Services.
Abstract: This paper proposes and implements a solution for enhancing public transportation management services based on GPS and GSM. Travel time information is a vital component of many intelligent transportation systems (ITS) applications. In recent years, the number of vehicles in India has increased tremendously, leading to severe traffic congestion and pollution in urban areas, particularly during peak periods. A desirable strategy to deal with such issues is to shift more people from personal vehicles to public transport by providing better service (comfort, convenience and so on). In this proposed system we introduced advanced public transportation systems (APTS) for public service. Advanced public transportation systems (APTS) are one of the most important ITS applications, which can significantly improve the traffic situation in India. One such application will be to provide accurate information about bus arrivals to passengers, leading to reduced waiting times at bus stops. This needs a real-time data collection technique, a quick and reliable prediction technique to calculate the expected travel time based on real-time data and informing the passengers regarding the same. The scope of this proposed system is to use global positioning system data collected from public transportation buses on urban roadways in the city of Chennai, India, to predict travel times. The performance of the proposed system is found to be promising and expected to be valuable in the development of advanced public transportation systems (APTS) in India. The work presented here is one of the first attempts at real-time short-term prediction of travel time for ITS applications in Indian traffic conditions.

Analysis and Optimization of an Electro-Thermally and Laterally Driven Poly-Silicon Micro-Actuator
Analysis and Optimization of an Electro-Thermally and Laterally Driven Poly-Silicon Micro-Actuator
Abstract: A Large displacement at low voltage is generally provided by electro-thermal mechanisms. A 3-D MEMS electro-thermal micro-actuator has been designed and simulated using COMSOL Multiphysics 4.3 which is geometrically optimized to explore the effect of dimensional variation on its performance. Metallic electro-thermal actuators provide large displacements at low voltages but at the same time, the maximum temperature in the device rises very sharply due to their highly conductive nature. To overcome this problem, a semi-conductor material; poly-silicon which is compatible with IC technology is used. For further improvements in terms of displacement and temperature, the geometry of the actuator is optimized.

Wavelet Based Image Watermarking
Wavelet Based Image Watermarking
Abstract: here it introduces an efficient multi-resolution watermarking methodology for copyright protection of digital images. By adapting the watermark signal to the wavelet coefficients, the proposed method is highly image adaptive and the watermark signal can be strengthen in the most significant parts of the image. As this property also increases the watermark visibility, usage of the human visual system is incorporated to prevent perceptual visibility of embedded watermark signal. Experimental results show that the proposed system preserves the image quality and is vulnerable against most common image processing distortions. Furthermore, the hierarchical nature of wavelet transform allows for detection of watermark at various resolutions, resulting in reduction of the computational load needed for watermark detection based on the noise level. The performance of the proposed system is shown to be superior to that of other available schemes reported in the literature.

Stiffness Characteristics of Joshi's External Stabilization System under Axial Compression: a Finite Element Method Based Study
Stiffness Characteristics of Joshi's External Stabilization System under Axial Compression: a Finite Element Method Based Study
Abstract: A finite element model of fractured tibia with Joshi's External Stabilizing System (JESS) mounted on it was developed using 3D beam elements in the ANSYS software. The model was loaded in axial compression and the average axial stiffness of the model was calculated. The analytical value of axial stiffness was compared with reported experimental value to validate the finite element model. The validated model was used to carry out parametric studies on the model to determine the axial properties of JESS. It was observed that axial stiffness of JESS increased by 58% when k-wire diameter was varied from 2 mm to 4 mm while keeping other geometric configurations of the device constant; however, the axial stiffness of the device does not show any significant improvement when the diameter of medio-lateral pins in diaphyseal hold were increased. The findings should help in understanding the axial properties of JESS so that it can be used judiciously in clinical applications.

Data Mining Based Skin Pixel Detection Applied On Human Images: A Study Paper
Data Mining Based Skin Pixel Detection Applied On Human Images: A Study Paper
Abstract: Skin segmentation is the process of the identifying the skin pixels in a image in a particular color model and dividing the images into skin and non-skin pixels. It is the process of find the particular skin of the image or video in a color model. Finding the regions of the images in human images to say these pixel regions are part of the image or videos is typically a preprocessing step in skin detection in computer vision, face detection or multi-view face detection. Skin pixel detection model converts the images into appropriate format in a color space and then classification process is being used for labeling of the skin and non-skin pixels. A skin classifier identifies the boundary of the skin image in a skin color model based on the training dataset. Here in this paper, we present the survey of the skin pixel segmentation using the learning algorithms.

Plasma Antenna
Plasma Antenna
Abstract: The fundamental base of plasma antenna is the use of an ionized medium as a conductor. The plasma antenna is a radiofrequency antenna formed by a plasma columns, Filaments or sheets, which are excited by a surface wave. The relevance of this device is how rapidly it can be turned on and off, only applying an electrical pulse. Besides its wide carrier frequency, the great directivity and controllable antenna shape. Otherwise a disadvantage is that it needs energy to be ionized. There are studies to reduce this power to ionize and maintain the plasma tube with higher plasma densities and frequencies.

Diagnostic Efficiency and Prognostic Value of Troponin T Measurement in Acute Myocardial Infarction
Diagnostic Efficiency and Prognostic Value of Troponin T Measurement in Acute Myocardial Infarction
Abstract: The diagnosis and prognosis of patients hospitalized with acute myocardial ischemia is quite variable. We examined the value of serum levels of cardiac Troponin T, serum CK-MB levels for detection of ischemic myocardial injury and risk stratification within 40 days in patients with acute myocardial ischemia with one specimen taken 2-8 hours of the onset of symptoms. Methods We studied 141 patients with a diagnosis of acute ischemic myocardial injury. The concentration of TnT and CK-MB is made on Coobas 6000 by a electrochemioluminescence and turbidometric methods. Results The median duration of the ischemic episodes qualifying the patients for the study was 4 hours. Chest pain was continuous in 51.8% and intermittent in 48.2%. Troponin T levels were elevated in 47 % of the patients whose ischemic symptoms had lasted more than seven hours (p= 0.06). 33% of the patients had the elevated troponin T level but CK-MB level was normal. Mortality within 40 days was significantly higher in these patients than in patients with lower levels of troponin T. The troponin T level was variable and most strongly related to 40-day mortality (chi-square=23, p<0,001) followed by CK-MB (chi-square=10, p=0,005). Conclusions The cardiac troponin T level is a powerful, independent risk marker useful in the diagnosis of infarction and in the identification of patients at increased risk of mortality and morbidity.

Word Problem Solver for Probability
Word Problem Solver for Probability
Abstract: Word Problems are designed to help students to learn the application of mathematical concepts, algebraic identities and formulae in the real world. Variables are assigned the values of "real-world‟ entities and a logical approach in solving them is established. They help the students to bridge the gap between theoretical knowledge and the real world application of it by giving them hypothetical situations about the same. Probability is a measure or estimation of how likely it is that a particular event will happen. Probability concepts need to be properly understood before attempting to solve any problem related to it. In view of this a survey was conducted. Students from various schools and coaching classes were approached for the same. The study shows that majority of the students experience difficulties in identifying and understanding what exactly the word problem signifies and what approach it demands. Also, the process of learning Probability needs to be specialized given the different understanding levels of each and every student in contrast to the generalized education techniques that are being used in traditional classrooms. Keeping in mind these issues, Word Problem Solver for Probability is implemented, which caters to the learning needs of each and every student individually by providing a step-by-step solution to all problems from the Probability domain.
Key words: Events, Probability, Problem Solver, Sample Space, Teaching Aid Word.

Performance Analysis of Wireless Networks With MDQOS
Performance Analysis of Wireless Networks With MDQOS
Abstract: In Wireless/Mobile networks various kinds of encoding schemes were used for transmission of data over a bandwidth. The desired quality and generated traffic varies with the requirement with this bandwidth. A generic video telephony may require more than 40 kbps whereas a low motion video telephony may require about 25 kbps for data transmission. From the designing point of view these requirements demands for an alternative resource planning, especially for bandwidth allocation in wireless networks. In wireless network where bandwidth is a scare resource, the system may need to block incoming user if all of the bandwidth has been used to provide highest quality of service to existing users. However this bandwidth resource planning may be unacceptable for larger application. A degradable approach to multiple users can be made on bandwidth allocation to reduce the blocking probability without degrading the quality of service to existing users.
This work aims towards a realization of a wireless/mobile network using W-CDMA multi access technique supporting multilevel quality of services. The bandwidth allocation to multiple users is adjusted dynamically according to the required network condition so as to increase bandwidth utilization. The work analyze the performance deriving the degradation period ratio, mean degradation time and degradation state for the implemented wireless network.The proposed work is aim to implement on Matlab tool for its functional verification considering various mobility patterns

Probability-Based Diagnostic Imaging Technique Using Error Functions for Active Structural Health Monitoring
Probability-Based Diagnostic Imaging Technique Using Error Functions for Active Structural Health Monitoring
Abstract: This study presents a novel probability-based diagnostic imaging (PDI) technique using error functions for active structural health monitoring (SHM). To achieve this, first the changes between baseline and current signals of each sensing path are measured, and by taking the root mean square of such changes, the energy of the scattered signal at different times can be calculated. Then, for different pairs of signal acquisition paths, an error function based on the energy of the scattered signals is introduced. Finally, the resultant error function is fused to the final estimation of the probability of damage presence in the monitoring area. As for applications, developed methods were employed to various damage identification cases, including cracks located in regions among an active sensor network with different configurations (pulse-echo and pitch-catch), and holes located in regions outside active network sensors with pitch-catch configuration. The results identified using experimental Lamb wave signals at different central frequencies corroborated that the developed PDI technique using error functions is capable of monitoring structural damage, regardless of its shape, size and location. The developed method doesn't need direct interpretation of overlaid and dispersed lamb wave components for damage identification and can monitor damage located anywhere in the structure. These bright advantages, qualify the above presented PDI method for online structural health monitoring.
Key words: Probability-based diagnostic imaging, Structural health monitoring, Lamb waves, Piezoelectric transducers, Scattered signal energy, Error function

FPGA Implementation of 2-D DCT & DWT Engines for Vision Based Tracking of Dynamic Obstacles
FPGA Implementation of 2-D DCT & DWT Engines for Vision Based Tracking of Dynamic Obstacles
Abstract: Real time motion estimation for tracking is a challenging task. Several techniques can transform an image into frequency domain, such as DCT, DFT and wavelet transform. Direct implementation of 2-D DCT takes N^4 multiplications for an N x N image which is impractical. The proposed architecture for implementation of 2-D DCT uses look up tables. They are used to store pre-computed vector products that completely eliminate the multiplier. This makes the architecture highly time efficient, and the routing delay and power consumption is also reduced significantly. Another approach, 2-D discrete wavelet transform based motion estimation (DWT-ME) provides substantial improvements in quality and area. The proposed architecture uses Haar wavelet transform for motion estimation. In this paper, we present the comparison of the performance of discrete cosine transform, discrete wavelet transform for implementation in motion estimation.

Modification of Recycled Al-332 Alloy Using Manganese Dioxide
Modification of Recycled Al-332 Alloy Using Manganese Dioxide
Abstract: Aluminum and its alloys are commercially available materials for both domestic (cooking utensils, beverages can) and industrial applications (automobile and aircraft structural parts). This study presented the effect of the use of manganese dioxide (MnO2), obtained from discarded dry cell batteries on the features and formation of pores in recycled pistons (Al-332 alloy). 3kg of recycled Al-332 alloy was obtained in form of ingot. 150 g of the ingot was re-melted and the molten alloy was treated with 2 to 12g of MnO2. The molten alloy was stirred gently for 1 minute, sand cast and normalized. Parts of the cast samples were used for microstructural analysis, tensile strength and hardness test following standard test procedures in accordance with ASTM E8M-91 standards (1992). The distribution of pores present in the cast alloys were studied using fractal analysis and spatial point pattern method (SPP). The hardness, tensile strength, average fractal dimensions and sphericities were related to the amount of MnO2. The micrographs revealed an absolute reduction in pores at 8gram addition of MnO2. Maximum hardness and tensile values of 50.8BHN and 65.01MN/m2 were obtained at 8 g addition of MnO2, above which there is decrease in properties of the material. The weighted average fractal dimension and sphericity for as-cast and sample treated with 8 g of MnO2 are 1.3276 and 0.3357; 1.0050 and 0.9918 respectively. Spatial point pattern revealed that the pores in the samples are randomly distributed. The study has established that manganese dioxide is a good modify for recycled Al-332 alloy. It improved the mechanical properties of the alloy and reduce the pores in the cast sample to the barest minimum.

Mitigation of Voltage Fluctuations in Power System Using STATCOM
Mitigation of Voltage Fluctuations in Power System Using STATCOM
Abstract: Wind energy being a renewable source of energy is enjoying a rapid growth globally. However, wind energy being an uncontrollable source of energy coupled with the fact that it uses distributed induction generators for power conversion poses a challenge in integrating a large scale wind-farm into a weak power system. An actual weak power system with two large Wind-Farms (WFs) coupled to it is introduced as part of this study. A model of this integrated system along with a STATCOM for steady state and dynamic impact study is developed in the MATLAB/Simulink environment. The power quality issues are highlighted and a centralized STATCOM is proposed to solve the issue of the voltage fluctuations in particular in addition to addressing the other issues. Based on the results obtained from the simulation, the system voltage control issues are analyzed and the location of STATCOM is assessed. Finally, a STATCOM control strategy for suppression of voltage fluctuations is presented.

Multi-View Algorithm for Face, Eyes and Eye State Detection in Human Image- Study Paper
Multi-View Algorithm for Face, Eyes and Eye State Detection in Human Image- Study Paper
Abstract: For fatigue detection such as in the application of driver‟s fatigue monitoring system, the eye state analysis is one of the important and deciding steps to determine the fatigue of driver‟s eyes. In this study, algorithms for face detection, eye detection and eye state analysis have been studied and presented as well as an efficient algorithm for detection of face, eyes have been proposed. Firstly the efficient algorithm for face detection method has been presented which find the face area in the human images. Then, novel algorithms for detection of eye region and eye state are introduced. In this paper we propose a multi-view based eye state detection to determine the state of the eye. With the help of skin color model, the algorithm detects the face regions in an YCbCr color model. By applying the skin segmentation which normally separates the skin and non-skin pixels of the images, it detects the face regions of the image under various lighting and noise conditions. Then from these face regions, the eye regions are extracted within those extracted face regions. Our proposed algorithms are fast and robust as there is not pattern match.
