Abstract

In current traffic system most of the traffic lights controls are based on a 'fixed timing' i.e., same time duration will be repeated even if the traffic density is minimum or maximum. In this paper the traffic light is controlled depending upon the traffic density is proposed. Here the traffic lights changes dynamically based on the traffic density by using pair of IR Sensor to continuously sense the density of traffic. The IR receiver output is given as the input of microcontroller in serial communication.The microcontroller will allocate the time slot according to the input of sensors, and then the CPU sends appropriate time to show on the seven segment display unit. When the allocated time is completed then the process will be shift into the next road. The same procedure it follows on each road. This system is designed by using PIC Microcontroller and three pairs of IR sensors on each lane. Here priority based operations by using the round robin algorithm is done. So, that each road will be cleared simultaneously. This system is mainly used to reduce the waiting time, avoid fuel wastage, and also manage the traffic load at the intersection adaptively, so that the traffic can be avoided.

Abstract

Background/Objectives: To analyze the Quality of Service in Cloud Computing and improve its services in the cloud environment. Method/Statistical Analysis: With the increasing use of services in cloud environment needs the improvements in the Quality of Services (QoS). Most cloud providers support Qos and it attract the customers due to its services. The Quality of Service (QoS) in cloud making the services efficient in the shared or distributed infrastructure and some companies are providing the cloud services are Microsoft, Amazon, Google and IBM.The use of Quality of Services based on the three approaches is comparison, evaluation and trustworthiness of the services to be analyzed and the QoSalso analyzed with the help of scheduling algorithms. Findings: Cloud services have some problems in which the data stored in cloud are not secure and occurrence of network dependency. The QoScan be decided for the services are based on the set of parameters such speed of the performance, processing, storage,memory allocation, security, functions, service response time and total throughput. The Quality of Services can be predicted based on the workflow model and the ranking prediction approaches. Applications/Improvements: The result observed from this work will serve as the motivation to improve the quality of service in cloud environment. The service response time and total throughput improvement will improve the QoS of cloud services.

Abstract

The programmable transducers can be used in the field of motor or generator   protection.  To overcome the error of existing system like overvoltage, under voltage and under frequency self aided programmable transducers are used. C based program is to be developed to interface the transducers and generator tripping device to the computer. The output devices are interfaced with the computer through specially designed drive circuits to energize the trip circuit of motor in case protection acts. The drive circuits consists of opto-coupler (for isolation purpose), switching transistors and PCB mounted small relays. The input circuit comprises of Transducers & A/D converter, the output circuit comprises of driving circuits for feeders. Audible alarms also can be generated through computer with the aid of buzzer circuits.  The input and the output circuits are connected to the PC through an Interfacing card through pc printer port.  All the transducers are connected to the PC through an A/D converter.
