Well-organized big data get together in the densely distributed sensor networks is, therefore, a challenging research area. One of the most effective solutions to address this challenge is to utilize the sink node’s mobility to facilitate the data gathering. While this technique can reduce energy consumption of the sensor nodes, the use of mobile sink presents additional Challenges such as determining the sink node’s trajectory and cluster formation prior to data collection. In this paper, we propose a new mobile sink routing and data gathering method through network clustering based on modified ExpectationMaximization (EM) technique. In addition, we derive an optimal number of clusters to minimize the energy consumption. The effectiveness of our proposal is verified through numerical results.
Rail inspection is an important task in railway maintenance. The speed and loads of trains have been increasing greatly in recent years, and these factors inevitably raise the risk of producing rail defects. Mainly the discrete surface defects impact the riding quality and safety of a railway system. However, it is a challenge to inspect such defects in a vision system because of illumination inequality and the variation of reflection property of rail surfaces. This project presents a realtime VIS for discrete surface defects of rail heads. VIS comprises the Image Acquisition Subsystem (IAS) and the image analysis subsystem. IAS acquires gray rail images for the surface of a rail head, and the latter processes rail images and detects possible defects. This paper propose the Local Normalization(LN) method to enhance the distinction between defects and background in a rail image, considering illumination inequality and the variation of reflection property of rail surfaces
The pre-engineered steel building system construction has great advantages to the single storey buildings, practical and efficient alternative to conventional buildings, the System representing one central model within multiple disciplines. Preengineered building creates and maintains in real time multidimensional, data rich views through a project support is currently being implemented by Staad pro software packages for design and engineering.
A Smart City is the integration of technology into a strategic approach to sustainability. 21st Century has brought with it a new global trend of “sustainable urban development” and this concept adds new dimensions to urbanization which require a quick need to upgrade existing cities. The concept of a smart city is a relatively new one. Throughout the years, with the significant contribution from various technologies like computer science, information technology, remote sensing, advance multimedia world etc, GIS evolved from traditional geographer’s or cartographer’s tool for surveying and planning to a rapidly expanding primary technology for understanding our planet and related geospatial opportunities to foster a sustainable world. This paper describes smart city projects in India and thoroughly explores the existing and extended capability of GIS to include modeling and visualization in order that decision makers will be able to
With the advancement in technology, various options to get latest news updates have increased significantly. News updates are easily available on web. So many users have shifted from traditional newspaper to digital news. This poses serious challenges to news providers where they need to make latest news readily available to user at all instants. Our project deals with similar issues and recommends news providers what exclusive news they are missing when compared to their competitors.
This article discussing about recently launched Google Android platform, and its online application marketplace for Android smart phones. The project examines the paths to success for third-party developers building applications for Android smart phones by comparing them with application development for the Apple iPhone and factors that influencing mobile brand selection while purchasing new mobiles. Research on related topics shows this mobile ecosystem benefits thirdparty developers and those application vendors play a critical role in contributing to the success of Android. In the current scenario most of the youngsters having Android smart phones in their hands, the reason for this development in a short period is usage social media such as face book, twitter and all other applications. Android platforms are simplified the use of social medias and access of it. In this article we can know further about this Android platform and its influence of peer purchase decision
In recent years, self-compacting concrete (SCC) has gained wide use for placement in congested reinforced concrete structures with difficult casting conditions. For such applications, the fresh concrete must possess high fluidity and good cohesiveness. In this present study, the effect of replacing the cement, fine aggregate and coarse aggregate by constant replacement of silica fume, Manufactured sand (JSW) replacement of 0%, 10%, 20%, 30%, 40% and light weight aggregate replacement of 10%, 15%, for internal curing respectively and their combinations of various proportions on the properties of different mixes of M40 grade has been compared with normal self compacting concrete by conventional curing method. In this study fresh property and hardened properties of the different mixes of concrete were determined. From the present study the test result showed that for fresh concrete all the mixes satisfies the EFNORC standard values.
Cloud computing is the apt technology for the decade. It allows user to store large amount of data in cloud storage and use as and when required, from any part of the world, via any terminal equipment. While Cloud services offer flexibility, scalability and economies of scale, there have been commensurate concerns about security. On the similar terms, we have chosen to make use of a combination of authentication technique and key exchange algorithm blended with an encryption algorithm. In this project, we have proposed to make use of 3DES algorithm which is a well-known symmetric cryptosystem and is widely used for secure data transmission, along with that we will blend it with Random Key Generator and Graphical Password to add an extra security measure. This proposed architecture of three way mechanism and the use of symmetric method of encryption make it tough for hackers to crack the security system, thereby protecting data stored in cloud.
Multi-attribute analysis is a useful tool in many economical, managerial, constructional, etc., problems. There is usually some uncertainty involved in all multi-attribute model inputs. The objective of this work is to demonstrate how simulation can be used to reflect fuzzy inputs, which allows more complete interpretation of model results. A case study is used to demonstrate the concept of general contractor choice of on the basis of multiple attributes of efficiency with fuzzy inputs applying COPRAS method. The work has concluded that the COPRAS method is appropriate to use.
- The present investigation was carried out at field trail of Main Experimental Station, Vegetable Science N.D.U.A. & T., Kumarganj, Faizabad (U.P.) during 2011-12 to study the performance of turmeric cultivars. Cultivar NDH-7 and NDH-8 was found superior in growth characteristics such as plant height, yield of rhizome/plant. NDH-8 found tallest (111.2 cm) while, yield of rhizome per plant was recorded in NDH-7 (303.00 g). The results showed that moisture, mineral, curcumin and essential oil ranged from 9.4 to 12.2 per cent, 3.39 to 5.30 per cent, 3.7 to 5.9 per cent and 3.32 to 8.19 per cent, respectively. NDH-7, NDH-8 and Prahba were found superior among all cultivars and variety.
