Existing driving behavior models have a strong emphasis on the driver’s cognitive components including aspects such as motivation, risk assessment, attention, compensation, capability, workload, individual traits and experience. Each existing model was designed specifically for a particular driving situation such as speeding or fatigue. This system defines a framework for a new context aware driving behavior model capable of predicting driver’s behavior. This approach broadens the cognitive focus of existing driving behavior models to integrate contextual information related to the vehicle, environment, driver and the interactions between them. In this system used to consist of different types of sensors such as alcohol sensor, eye blink sensor, lane detection sensor, heart beat sensor, accident sensor. And also mainly used to GSM modem, GPS receiver, RFID reader and finger print scanner. GSM and GPS based vehicle location and tracking system will provide effective, real time vehicle location, mapping and reporting this information value and adds by improving the level of service provided. The system has an “On Board Module" which resides in the vehicle to be tracked and a "Base Station" that monitors data from the various vehicles. The On Board module consists of GPS receiver, a GSM modem. The Alcohol Sensor is used to sense weather the person driving the car taken Alcohol or not and this data is also given to ADC, The ADC is used in this system because the signal comes from the Sensors are analog in nature, so we want to convert the Analog signals into digital signal for this purpose ADC is used. Heart Beat sensor used in the system is used to sense the heart beat of the person driving the vehicle and sends the data to the embedded system, and the eye blink sensor is used to sense the person driving the vehicle is sleeping or not. Accident sensor is used to identify weather the vehicle is running in normal condition or not when the accident occurs it send the information to the embedded system. The Embedded system is programmed like when it receives the signal from the signal sensor it activates the Vehicle system control system and level converter unit. And also this system consist of RFID reader and finger print sensor is used to prevent non-licensees from driving and therefore causing accidents. And identify the person going to drive the vehicle is the owner of the vehicle or not.

Parallel programming represents the next turning point in how software engineers write software. Today, low-cost multicore processors are widely available for both desktop computers and laptops. As a result, applications will increasingly need to be paralleled to fully exploit the multicore-processor throughput gains that are becoming available. Unfortunately, writing parallel code is more complex than writing serial code. This is where the OpenMP programming model enters the parallel computing picture. OpenMP helps developers create multithreaded applications more easily while retaining the look and feel of serial programming. The term algorithm performance is a systematic and quantitative approach for constructing software systems to meet the performance objectives such as response time, throughput, scalability and resource utilization. The performances (speedup) of parallel algorithms on multi-core system have been presented in this paper. The experimental results on a multi-core processor show that the proposed parallel algorithms achieves good performance compared to the sequential.

In order to increase the reliability and efficiency of distributed micro-generation a modular grid-connected inverter system is proposed. It consists of a modular DC-DC converter and modular DC-AC converter. Output of the DC-DC converter and input of the DC-AC inverter is connected with a DC bus .The By using the DC-DC converter voltage can be stepped up and Maximum power point tracking can be achieved In this system no transformer is used in the inverter side to inject the voltage into the grid. Here the Voltage is injected in the grid using inductor filter. The practicability of the proposed system has been verified by simulation results.

In general, existing cQA forums provide only textual answers, which are not informative enough for many questions. Conventional MMQA aims to seek multimedia answers without the assistance of textual answers. This MMQA scheme using diversification method is able to enrich textual answers in cQA with appropriate meta data which improves the informativeness and it bridges two gaps (i) The gap between questions and textual answers (ii) The gap between textual answer and multimedia answer. This scheme consists of three components: answer medium selection, query generation and data selection and presentation. This scheme determines the type of media information that can be added for a textual answer. This scheme predicts the type of medium to be added using Naïve Bayes Classifier, it automatically generates query based on QA knowledge and performs multimedia search. Finally this scheme performs query adaptive re-ranking and duplicate removal to obtain a set of images and videos for presentation along with textual answer. This scheme uses diversification methods to make the enriched media data more diverse. This scheme uses Page Ranking algorithm to retrieve more relevant and diverse search results.

Clustering is a process that partitions data in such a way that homogeneous data items are grouped into sets which is referred to as clusters. When the content or structure changes over time of the multi-version XML documents then Clustering is done. In real-world applications, the number of changes from one version of an XML document to another version of an XML document cannot be predicted. It is always possible that an initial clustering solution becomes obsolete after the modification take place in document. XML clustering algorithms is use to calculate pair-wise distances between documents. A time-efficient technique determined the pair-wise distances in a timely manner. In this paper we proposed a time-efficient technique to reassess pair- wise distances between clustered multi-version XML documents which change over a time, without performing redundant calculations. While performing redundant calculations we considering the previously known distances and the set of changes which might have affected the documents versions Mining is the process of searching the XML documents from the formed clusters and extracting the particular data from that searched XML document. For mining we have one Metric which has details that in which cluster a particular record should be. So when we want any reports we directly go to metric and see where we will find¬ that records and directly access files inside that cluster.

In this Paper numerical study with swept ramp injection in supersonic combustion of hydrogen has been presented. Coupled implicit scheme with finite rate chemistry model and K-? Turbulence model have been used for modeling of supersonic combustion. The main issue in supersonic combustion is proper mixing within short burst of time. Because of the step on the top wall of the combustor, there exists an expansion fan generated just on the top wall at the entrance of the combustor, which is interacts with the oblique shock wave formed upstream of the combustor due to the shear layer deflecting into the core flow. The static pressures along the walls are normalized by the static pressure of the core flow. The present result is very promising and demonstrates that flamelet approach seems to be feasible to high-speed flows. The stagnation temperature in the combustion reaches up to 2830 k. Fluctuation in pressure and Mach number was due to shock train.

To investigate the protective effect of ?-Tocopherol (?-TP) in monosodium glutamate (MSG) induced liver injury in albino rat model. Experimental/Analytical study Place and Duration: Animal House, Isra University Hyderabad from February to September 2013.Subjects and Methods: Sixty albino rats were divided into three groups; Group 1. Controls received 0.9% isotonic saline, Group 2. received MSG orally (3mg/kg), and Group 3. received the MSG orally (3mg/kg) + ?-TP (0.2 mg/kg). Blood samples were collected for liver biochemical assays. The animals were sacrificed, liver tissue, after fixation in 4% formaldehyde, was embedded in paraffin. Tissue sections of 5? thickness were subjected to haematoxylin and eosin staining and were assessed by light microscopy. The data was analyzed on SPSS 21.0 using appropriate statistical tests. A p-value of ? 0.05 was taken statistically significant.Results: The liver biochemical and histological findings reveal statistically significant differences among the controls, MSG and MSG+ ?-TP groups (p=0.0001). Liver enzymes and histology was deranged significantly in MSG group compared to controls and MSG+?-TP group (p=0.0001). The MSG+?-TP group shows less elevation of liver enzymes and derangement in liver histology when compared to MSG group (p=0.001). The histological findings of congestion, inflammatory cell infiltrate, vacuolar degeneration and necrosis were found prominently in MSG group animal. The monosodium glutamate has deleterious effects on liver. It is important to reconsider the monosodium glutamate as a food flavor additive. ?-tocopherol protects against monosodium glutamate induced liver injury.
