Abstract: The performance of artificial vision as a nondestructive technology has been evaluated in monitoring beef meat quality at a storage temperature of 4°C for more than two weeks. A reference method based on bacteriological measurement is performed in parallel with the artificial vision system to analyse the meat samples. Artificial vision data were collected from color image of meat samples in parallel with data from microbiological analysis for the enumeration of the population dynamics of total viable counts (TVC). Two color models are used to define fresh beef color in this study: the RGB (Red, Green and Blue) and HSI (Hue, Satutation and Intensity) model. Fuzzy ARTMAP artificial neural network based on a classification technique is used to investigate the performance of the artificial vision system in the quality classification of beef meat. The Fuzzy ARTMAP models built classified beef meat samples based on the total microbial population into “unspoiled” (microbial counts < 6 log10 cfu/g) and “spoiled” (microbial counts ≥ 6 log10 cfu/g). Good classification rates are obtained (95.24 %). Finally training and testing an artificial system will be considered as a useful alternative tool for beef meat quality assesement.

Abstract: After a heart attack, the first few hours are critical in saving much of the dying heart muscle which are starving due to lack of oxygen supply and preventing permanent heart damage. The symptoms vary from individual to individual and the most common reason for critical delays is medical treatment is patient unawareness and lack of early warning. It is possible to detect the onset of a heart attack and inform the doctor or person concerned. By implanting a chip into the body, the patient need not worry about device operation. The patient will only be required to carry a cell phone equipped with Bluetooth and GPS. As soon as the implanted chip detects a heart attack, it will alert the cell phone which in turn will automatically call for help and provide the patient’s location. Thus it helps in providing early heart attack detection so that the patient can get medical attention within the first few critical hours. It consists of three basic sub projects ECG Circuit, Analysis Algorithm, GPS module, GSM module and microcontroller. The first unit is worn on the user’s wrist captures abnormal heart beat signal from the patient , and the rest units are installed in the stick. The microcontroller on the stick runs a heart attack algorithm. Warning is given out to the person about his heart condition. The emergency calling system calls for medical help at the moment of heart attack. The effectiveness of the proposed method is confirmed by experiments on a commercially available walking stick. Each of the subprojects responded positively. The proposed Walking Stick with Heart Attack Detection is cost effective and can save the lives of millions of old people by helping them in getting the earliest medical help in the condition of heart attack. Here we use GPS device and GSM module so at a worst conditions it will directly call 108 emergency and patient’s life will be saved.

Abstract: Authentication based on biometrics is being applied to control physical access to high-security facilities. Recently, with the recent rapid growth of information system technologies, applications for accessing databases or business workflow systems have begun to use biometrics such as hand geometry, palm, iris, fingerprint etc. As the integrity of data is important, We have to guarantee the integrity of the registered biometric data. This paper presents an identification-verification biometric system based on the combination of hand geometry features. The system is designed in NI Vision Assistant 2009. Such approach increased both detection and recognition efficiency of our palm and finger print biometrics system. The proposed system is reliable and user friendly as it is developed in Vision Assistant software. The availability of data log files in Vision Assistant and LabVIEW makes it one of the most useful component as a database.

Abstract: This paper implements & develops a wheel chair control for the physically challenged by employing head gesture recognition using MEMS technology. Tremendous advances have been made in the field of wheelchair technology; however, even these significant advances haven’t been effective in helping unassisted quadriplegics to navigate the wheelchair. Here, a simple cost effective wheelchair is developed which can be controlled by simple head gestures for directions like left, right, front, and back. An accelerometer MEMS sensor is used to control the wheelchair through head gestures made by the impaired person and moves accordingly. This paper also presents the experimental results on the movement responses of the developed wheel chair with patients of varying weight.

Abstract: Design of controller for the process operation is typically based on the availability of the best model. Development of empirical model is incorporated with many assumptions and approximations. System identification is developed to alleviate this problem by considering the input and output data of the process for the model development. The cascaded tank process is highly nonlinear and non-minimum phase process and often its working conditions are variable. Due to inadequacy of linear system identification to capture the dynamic of process, nonlinear system identification is incorporated. Identification of Cascaded two tank process using wiener model is reported. Wiener model parameters are estimated using recursive prediction error method.

Abstract: The operation of generating units to generate energy at reduced cost to reliably serve consumers, recognizing any operational restrictions of generation and transmission facilities is called as Economic Dispatch(ED).In the present paper, an evolutionary modified Deterministic Particle Swarm Optimization (DPSO) is applied for Environmental and Economic Power Dispatch (EED) problem to find fast and efficient solutions for IEEE 14 and 30 bus systems. In such a way, proposed algorithms reduce the total expenditure task of the generating units and improve the computational efficiency. The feasibility of the proposed DPSO based algorithm is demonstrated for two power system test cases consisting of IEEE 14 bus 3-generator system and 30 bus 6-generator system. The results obtained are compared to previous PSO, GA.

Abstract: With continued scaling of silicon process technology, producing reliable electronic components in extremely denser technologies pose a challenge. Further, the systems fabricated in deep sub-micron technology are prone to intermittent or transient faults, causing unidirectional errors, upon exposure to ionizing radiations during system operation. The ability to operate in the intended manner even in the presence of faults is an important objective of all electronic systems. In order to achieve fault-tolerance, each module of the system must be fault-tolerant by possessing run-time (or online) fault detection capabilities. Totally Self-checking (TSC) circuits permit online detection of hardware faults. The objective of this project is to analyze the area (resource utilization), speed and power consumption for n bit Look-Up Table (LUT) implementation with and without fault detection capability using Berger technique on Xilinx FPGA. The Berger code is the least redundant systematic code available for detecting all single and multi-bit unidirectional errors. This project is proposed to find the fault in 4, 8, 16, 32 bits LUT. The fault will be detected by Berger checker architecture.

Abstract: This paper is based on the analysis of the various algorithms in cryptography technique. With the fast changing technologies in today, more data are generated and transmitted. If the confidentiality of the information is very high, it should be protected. Cryptography is used to protect the personal or important data from the unauthorized people who try to access it. Cryptography is widely used by government and intelligence agencies around the world for the transmission of information. It can be either online offline. In this paper various cryptography algorithms are studied and compared.

Abstract: Surveillance is a critical problem for harbor protection, border control or the security of commercial facilities. The effective protection of vast near-coast sea surfaces and busy harbor areas from intrusions of unauthorized marine vessels, such as pirates, smugglers, illegal fishermen is particularly challenging. The main aim is to detect the ship, which cross over the border or secured industries using ultrasonic sensor and axis sensor. These sensors are placed on grid for every 40km apart when the intrusion is passed away the sensor, it senses the obstacle and measures the intruder angle and distance. This will be displayed in the form of graphical representation in LabVIEW (Laboratory Virtual Instrumentation Engineers Workbench). An alert message will be sending to control room using GSM (Global System for Mobile communication).
