CFD Analysis of Automotive Ventilated Disc Brake Rotor
CFD Analysis of Automotive Ventilated Disc Brake Rotor
Abstract: Disc brakes work on the principle of friction by converting kinetic energy into heat energy. The key objective of a disc brake rotor is to accumulate this heat energy and dissipate it immediately. The effect of rotational speed on the aero-thermal performance is assessed. The rotor speed is observed to have substantial effect on the rotor performance. The heat dissipation and thermal performance of ventilated brake discs intensely be influenced by the aerodynamic characteristics of the air flow through the rotor passages. In order to investigate the aero-thermal performance of the ventilated disc brake at several altered driving speeds of the vehicle, the simulations were carried out at 3 different rotational speeds of 44rad/s 88 rad/s and 120 rad/s. The semi-automatic geometric model is created using the package Solid Works and the mesh for the model is done using ICEM CFD and the Post processing of the results is done using FLUENT-14.5.The results are discussed and presented in detail.
Key words: Brake rotor, convection, heat transfer, rotor speed, flow rate

RF Based Spy Robot
RF Based Spy Robot
Abstract: The intention of this paper is to reduce human victims in terrorist attack such as 26/11. So this problem can be overcome by designing the RF based spy robot which involves wireless camera. so that from this we can examine rivals when it required. This robot can quietly enter into enemy area and sends us the information via wireless camera. On the other hand one more feature is added in this robot that is colour sensor. Colour sensor senses the colour of surface and according to that robot will change its colour. Because of this feature this robot can't easily detected by enemies. The movement of this robot is wirelessly controlled by a hand held RF transmitter to send commands to the RF receiver mounted on the moving robot. Since human life is always Valueable, these robots are the substitution of soldiers in war areas. This spy robot can also be used in star hotels, shopping malls, jewelry show rooms, etc where there can be threat from intruders or terrorists.
Key words: wireless, robots, spy robot, colour sensor, gas sensor

Segmentation - Offset Based Image Classification
Segmentation - Offset Based Image Classification
Abstract: In industrial applications, product identification is the most common thing now days. To kept in mind that we focus on the classification of our industrial product with the help of its texture using segmentation [7] and offset. Texture plays an important role in identifying the characteristics of an image/product. Image has visual features which are characterized as: (i) domain specific features like figure prints, human face etc. (ii) general features like colour, texture, shape. Texture of an image gives us information about the spatial arrangement of intensity values in an image or over the selected region of an image. We will describe the textural features based on gray-tone spatial dependencies.
Key words: GLCM, Gray tone spatial orientation, Segmentation, Offset.

Alcohol Detection and Automatic Drunken Drive Avoiding System
Alcohol Detection and Automatic Drunken Drive Avoiding System
Abstract: The main aim of this project is to design an embedded system for implementing a efficient alcohol detection system that will be useful to avoid accidents. There are many different types of accidents which occur in daily life. Accidents may cause due to many reasons it may be due to brake fail. Most often accidents occur due to over drunken person. Though there are laws to punish drunken drivers they cannot be fully implemented. Because traffic police cannot stand on every road to check each and every car driver whether he/she has drunk or not. This can be a major reason for accidents. So there is a need for a effective system to check drunken drivers. Therefore in order to avoid these accidents we have implemented a prototype project. In our project, Initially we check whether the person has drunken or not by using the MQ3 GAS sensor. In this system, sensor circuit is used to detect whether the alcohol was consumed by driver or not. To this end, we have designed such a system that when alcohol concentration is detected then car will be stopped and the related information will go to nearby location through GSM. This project is based on EMBEDDED C programming using AVR-AT mega 16 microcontroller.
Key words: Embedded system, MQ3 alcohol sensor, AVR-AT mega 16 microcontroller, GSM.

Performance of Three-Arm Ac Automatic Voltage Regulator
Performance of Three-Arm Ac Automatic Voltage Regulator
Abstract: In this paper the design and simulation of automatic voltage regulator (AVR) is proposed. The AVR provides voltage buck and boost capability to eliminate power problems created by under voltage or over voltage fluctuations. It also protects against minor and severe spikes and surges that comprise over 80% of power problems. Over heating of components due to voltage swell is also avoided by using AVR. The switching losses are also reduced as only one arm among three arms is maintained at higher power frequencies depending on mode of operation. Moreover, there is no need to use large capacitor as a result the overall size of converter is also reduced. Hence, the output voltage of the AVR can be maintained at the specified voltage. Hence, the AVR is cost can be reduced, and the efficiency of the power convertor can be extended.
Index Terms: AC boost converter, ac buck converter, automatic voltage regulator (AVR).

Optimum Overcurrent Relay Coordination of a Power Grid
Optimum Overcurrent Relay Coordination of a Power Grid
Abstract: Protective system plays a pivotal role in any power system operation. In a typical power system there are large numbers of circuit breakers and relays installed which constitute an integral part of the protective scheme. Relay is a device that senses and locates the fault and sends a command to the circuit breaker to disconnect the faulty element. Relay coordination is done to provide primary as well as back up protection from any fault that is likely to occur in the system. In this paper, overcurrent relay coordination is implemented on a 72 bus 220 KV substation. Load flow studies and the short circuit analysis on the test system is initially done followed by relay coordination. Fault current data obtained from short circuit studies enables us to obtain operating time of the relays used in the test system. The simulated value of operating time provides the coordinated operation of all the relays connected from 220kV to 33kV line thereby protecting the equipment of the test system.
Key words: PSM (Plug Setting Multiplier), Relay coordination, Three phase to ground fault, TMS (Time Multiplier Settings)

Design Of Digital Configurable Error Free Frequency Detector Using Strobe Signal.
Design Of Digital Configurable Error Free Frequency Detector Using Strobe Signal.
Abstract: This paper presents a glitch free module using strobe signal which overcomes the limitation of delay mismatch in a wide range of applications. The proposed strobe signal logic can control the occurrence of glitch at both the rising edge and falling edge of the circuit. The theoretical demonstration of the glitch free operation of the proposed strobe signal module is also derived in the paper. The previously proposed digitally controlled delay lines (DCDL) has been compared to this technology. Simulation results show the correctness of the module with no delay mismatch with respect to the previously proposed DCDL. As an example application, the strobe signal logic is used in configurable error free frequency detector (a frequency counter) which can control the occurrence of glitch during the sudden modulation of the frequency. The employ of the proposed strobe signal can hold the operation of the gate for a specific time until the other gate completes its operation so that there is no delay mismatch.
Key words: Digitally controlled delay lines(DCDL), Integral non linearity(INL),strobe signal, configurable error free frequency detector.

Automatic Detection of Tumor in Wireless Capsule Endoscopy Images Using Energy Based Textural Features and SVM Based RFE Approach
Automatic Detection of Tumor in Wireless Capsule Endoscopy Images Using Energy Based Textural Features and SVM Based RFE Approach
Abstract: This paper deals with processing of wireless capsule endoscopy (WCE) images from gastrointestinal tract, by extracting textural features and developing a suitable classifier to recognize as a normal or abnormal /tumor image. Images obtained from WCE are prone to noise. To reduce the noise, filtration technique is used. The quality of the filtered image is degraded, so to enhance the quality of the image, discrete wavelet transform (DWT) is used. The textural features (average, energy) are obtained from DWT for three color spaces (RGB, HSI, Lab). Feature selection is based on support vector machine- recursive feature elimination approach.
Key words: Discrete Wavelet Transform (DWT), Feature selection, Support Vector Machine (SVM), Texture, Wireless Capsule Endoscopy (WCE).
