It is a network which mainly focus on providing applications which save human lives and provide comfort to drivers during driving. So, Communication which are of two types, vehicle to vehicle (V2V) or Inter-vehicle Communication(IVC) and vehicle to Infrastructure(V2I) or Vehicle to Road Side Units(V2R), plays a major role because there is need that safety message to delivered on time without being any manipulation done by the intermediate nodes. Security plays a major role in VANET for the reliable and efficient delivery of message, Trust a key element of security. It is basically a belief which one node has over the other when it receives information from it. This trust can either be on the node i.e. Entity Centric Trust which provided the information or this trust can be developed on information provided by the node, that is data centric trust or can be on both node as well as on information, that is combined trust. In this, we focus on data centric approach and introduce a similarity metric aided by the infrastructure, to propose our own trust model. Simulation results, shows the accuracy of our trust scheme in respect with the introduction of malicious data.

A finite state machine (FSM) based digital control circuit is designed and developed for the baseline compensation. In order to achieve high accuracy, the digital baseline compensation circuit also incorporates the current digital-to-analog converter (CDAC) and successive approximation current analog-to-digital converter (CADC). The minimum LSB current for the CADC is 10nA. The readout circuit is implemented in the integrated chip with chip area of 125μm × 46μm and fabricated via TSMC T18 process. With standard 3.3V supply, the experimental result shows that the overall power consumption of the chip is 990μW watt. Despite of all parasitic capacitances of the panel display, experimental results show that the proposed circuit can sense 0.5nA current within 7μs of settling time. The se...

Such data driven applications which are executed on large clusters set up in data centers hike the energy cost which imposes burden on overall data center cost. Thus minimizing parameter that guides energy consumption becomes paramount requisite to be considered. In this paper we propose a framework for improving energy efficiency of Map Reduce applications. We propose phase level energy aware map reduce scheduling algorithms that assign map and reduce task to system on the basis of maximum node availability. We perform various extensive experiments on Hadoop cluster to determine execution time and energy consumption for several workloads from Hadoop including Terasort and K-means clustering and results evaluated that proposed algorithm consume less energy than various heuristic algorithms and minimizes execution time.

A Survey on the Techniques to Improve the Visibility of Geospatial Resources on the Web

The demand to access geospatial data on the web is growing in numerous knowledge domains and disciplines. For the sharing of geospatial data, geoportals acts as entryways to the SDI (spatial data infrastructure) from where the data is disseminated. Because these geoportals are limited to geoinformation communities only, they exhibit challenges in terms of indexing by web search engines. Thus, the geospatial resources need a boost in terms of visibility over the internet (web). In this chapter, a discussion on the present state of geospatial resources on the web and comparison of various methods that have been employed for increasing the discoverability of geographical resources is presented. Therefrom, by discussion, the chapter concludes with a conjecture regarding scope for the further improvement in the methods that have been reviewed, along with depicting the need for the presence of geospatial resources on the internet.

Blood Pressure is one of the most important parameters that can provide valuable information of personal healthcare. A reflective photoplethysmography (PPG) sensor module is developed for the cuffless, non-invasive blood pressure (BP) measurement based on PPG at wrist on radial artery. Blood Pressure is in a relation with the pulse duration of the PPG. In this paper, we propose to estimate blood pressure from PPG signal by using artificial neural networks approach. This is the first reported study to consider varied temporal periods of PPG waveforms as features for application of artificial neural networks (ANNs) to estimate blood pressure. We compared our results with those measured using a commercial cuff-based digital blood pressure measuring device and obtained encouraging results of overall SBP and DBP regression (R) as 0.99115.

Web applications and web technologies are changing the world rapidly. Web applications has become the most important feature of any business specially to showcase what they are offering and tools to use their products. To meet current business needs, web applications have become quite complex to develop, the number of files has increased and as the application grows it becomes difficult for the developer to maintain the application and as well as test the application. At the same time, we have web applications that are used as a service by various enterprises, these applications are modified according to the need of the customers, which sometime results in building the application again and modifying the app according to the customer needs, this process sometimes leads to regression which increases the delivery time as developers have to find out the root cause of the issue. To solve this issue what if we divide the whole application into components that are capable of functioning independently, we can add or remove the functionality according to our needs and it would be easier for developers to build the application even from scratch. Now, since the application is divided into components we can maintain and test these components independently allowing developers to reduce the time taken in a release cycle. In this paper my aim is to automate the process of creating a website that can be modified according to the user need without making change on the code level and also to automate the whole process using Web Components.

This is a rare anatomic variant, prevalence of which ranges between 5.96 and 6.67% in the Indian population. For a successful endodontic management, detection of these extra roots is important. In conventional radiography, these extra roots tend to be overlapped; thus, conebeam computed tomography (CBCT) provides a noninvasive technique to study the internal and external anatomy and aids in proper detection. The endodontic treatment of RE requires some modifications in the endodontic treatment as compared with the common two-rooted anatomic variant. This article presents a clinical case report of successful detection and endodontic management of mandibular first and second molar with extralingual root using CBCT as a diagnostic tool. This case report involves the endodontic treatment and presence of extra roots in both the mandibular first molar and second molar simultaneously in a single patient of Indian origin, which is a rare finding and has not been reported in endodontic literature till date.

Due to the absence of centralized administration and dynamic nature, MANETs are vulnerable to various kinds of attacks from malicious nodes. Several secure routing protocols like AODV, DSR, TSR, and OLSR have been used in MANET for transmission of data. In MANET, we are using trust based QoS aware routing protocol for identifying the malicious nodes in the network. Trust is mandatory in routing for transmission of data securely. Hence trust models, trust computation is implemented in the routing protocols. In this paper, survey of several trusts based and QoS aware routing protocol is performed. In this review paper, the study of different trust based and QoS aware AODV protocols that are using trusted infrastructure and trust models is performed for preventing the attacks and misbehavior from malicious nodes in the network. The performance of trust based routing protocol has been analyzed that helps to work efficiently and can be used in various applications of MANETs for improving the security performance of the network.

Variation in Cone and Seed Morphology of Pinus roxburghii Sargent : Effect of Population and Mother Tree

The populations studied constituted a continuous stretch of this species. Between-population variation for the cone and seed characteristics was found to be very small as it ranged from 0 per cent to 26 per cent, depending upon the trait. The remaining 74 per cent or more of the variation in these characters was due to the between-tree within-population and the within-tree components. The study showed that if seed collectors are interested in cones of greater weight or length, they should search for trees possessing such cone or seed characteristics within their own planting region, rather than trying to find specific populations for such characteristics outside their planting region, because much of the variation in these traits is accounted for by differences between trees, rather than between populations. Else, they should search for desired stands in distantly located populations or in populations separated by some geographic barrier.
