For the ‘24/7/365’ world we live in, the user now demands the same services in the car as the office or home; emails, music, gaming and video, along with increased safety. A single IP-based network is the key, enabling the car to enter the World Wide Web. Implementing Ethernet at the OBD port now allows the car to interface to the World Wide Web, creating endless possibilities. For example, the port can easily be plugged into a wireless unit for remote diagnostics or downloads for in-car navigation, video or music, all from the comfort of the owner’s home!. The next step is for Ethernet to form the backbone of the next generation automotive multi-media networks, carrying ‘live’ traffic. Standards such as IEEE 802.3AVB (Audi-Video Bridging) initially defined for Digital AV Home networking are being adapted to support the same real-time services in the car. Following this the ultimate goal would to converge other bus systems inside the car into a single common bus; Ethernet.
The main objective of this project is to improve the Road Vehicle safety features and to improve the global efficiency of the transportation system by reducing travel time and congestion, using a well defined durable development policy. Effective use of this Intelligent Transport System (ITS) is not only to improve the vehicular safety but also to enhance the efficiency of current transport system and driving comfort. The key point of ITS is how Vehicles communicate with each other, which means we need a set of communication protocols to facilitate moving vehicles. The traditional system is very costly due to deployment and is characterized by a long reaction time for processing and information transfer. The Goal of ITS is to improve security, efficiency and enjoyment in road transport through the use of New Technologies for Information and Communication (NTIC) with minimum cost. This system consists of sensor devices which are fixed in the vehicle and a Motor driver. The sensor devices monitor the position of the vehicle and send the relevant information to the microcontroller and it is displayed. The motor driver determines the speed of the motor based on the requirement of zones using zigbee wireless technology. The system is designed around the microcontroller with zigbee wireless technology to communicate between V-V for a wider communication range. It has been developed as a system for the vehicle to communicate with the neighboring vehicle by broadcasting their safety-critical information and alert the neighboring vehicles from possible collisions. It provides good feature to our cars and roads with capabilities to make the road more secure and to make our time on the road more enjoyable.
There is a huge market of noninvasive devices to measure the parameters. But they have limitations like either they are continuously health monitoring system or they can measure only one parameter and keep records. The health monitoring systems which are used in multispecialty hospitals are very bulky and costly. This paper proposes a design and implementation of a reliable, cheap, low powered non-intrusive and accurate system that can measure many parameters of human body and keep the records of each patient. It gives an idea to make a database of each patient so that whenever the patient comes to the doctor he doesn’t have to keep his record with him manually. Such a device can be handled by non technical personnel also and can be used both in small clinics and big hospitals. This paper is presented with a motto of saving time of both the doctor and patients. As the device can measure the vital signs in a very less time it can save time of doctor and no. of patients can be observed. This paper specifically deals with the signal conditioning and data acquisition of three vital signs: heart rate, body temperature, and weight. The vital signs that have been taken are temperature, heart rate and body mass index. The heart rate is measured by Heart beat sensor which works on the principle of light modulation by blood flow through finger at each pulse. The temperature is measured by using LM34 which measures the temperature directly in Fahrenheit and does not need external calibrations. And the weight is measured by load cell. Here a simple circuit is designed by using AT89S52 microcontroller as heart of the circuit. The three sensors are connected with microcontroller via signal conditioning equipments. The data is also easily accessible by both the doctor and patient as complete record of output can be generated by using VB as programming language.
The performance of fuzzy-logic power system stabilizer (FPSS), which is tuned automatically as the operatin conditions of power system change, is investigated by applying it to a single-machine power system. FPSS is developed using speed deviation and the derivative of speed deviation as the controller inputs variables. Two scaling parameters are introduced to tune the FPSS. These scaling parameters are the output of another fuzzy-logic system (FLS), which gets its inputs from the operating condition of the power system. The performance of the fuzzy PSS (FPSS) is compared with the conventional power system stabilizer (CPSS). The simulations were tested under different with different membership functions such as trapezoidal, triangular and Gaussian membership functions. The simulation results are quite encouraging and satisfactory.
Recognition of any ancient Tamil characters with respect to any language is complicated, since the ancient Tamil characters differ in written format, intensity, scale, style, and orientation, from person to person. Researchers for the recognition of ancient Tamil languages and scripts are comparatively less with other languages, this is a result of the lack of utilities such as Tamil text databases, dictionaries etc. The problem of ancient Tamil character recognition is the technical challenge than other languages in respects to the similarity and complexity of characters that are composed of circles, holes, loops and curves. Hence ancient Tamil recognition requires more research to reach the ultimate goal of machine simulation of human reading. In this paper, we have made an attempt to recognize ancient Tamil characters by using SIFT features and presented a new and efficient approach based on bag-of key points representation. Collection of SIFT features are first extracted from local patches on the pre-processed images, and they are then quantized by K-means algorithm to form the bag-of-key points representation of the original images. These fixed-length feature vectors are used to classify the characters. A recognition system consists of the activities, namely, digitization, pre-processing, feature extraction and classification. This system achieves a maximum recognition accuracy of 84% using SIFT features.
