In its most straightforward structure, cement is a blend of cement and aggregates, or stones. The glue, made out of portland bond and water, coats the surface of the fine (little) and coarse (bigger) aggregates. Prestressed cement is a strategy for conquering solid's normal shortcoming in pressure. It can be utilized to deliver pillars, floors or extensions with a more extended range than is useful with standard strengthened cement. It is regularly utilized as a part of business and private development as an establishment piece. Prestressing tendons (for the most part of high rigidity steel link or poles) are utilized to give a cinching load which delivers a compressive anxiety that adjusts the ductile anxiety that the solid pressure part would somehow encounter because of a bowing load.Traditional fortified cement depends on the utilization of steel fortification bars, rebars, inside poured concrete. Prestressing can be expert in three ways: pretensioned concrete, and reinforced or unbonded post-tensioned cement. The prestressing of concrete has a few favorable circumstances when contrasted with conventional strengthened concrete without prestressing. A completely prestressed solid part is generally subjected to pressure amid administration life. This corrects a few insufficiencies of concrete like reduction in occurrence of cracks, increase in shear capacity etc.

Now a day’s picture revival plays an important role in diagnosis where a laboratory person can retrieve most similar images from arranging images over a query image of a specific patient. On this spot, we have to confinement the just done the circumspect picture as well as affirmation of assertion on the base of the local crosswise arrangement is received for CT picture renewal. The expected strategy approach has to recommendation the values as well as indexes of the local crosswise extremes to exploit the exchange among the crosswise neighbours of any centre point valve of the picture by using first-order invention process. The consequence values of the local bias depth are linked among the consequence value of the centre point to handle the exchange of centre point along its neighbours. Ultimately, the narrative is created on the base of ratio along with comparison of centre point among the local crosswise depth. The examination of only crosswise neighbours greatly reduces the dimension of the feature vector which stimulates the image retrieval task and solves the “malediction of dimensionality” problem also. The LDEP is used to test the CT picture revival in NEMA computer tomography and compared with the actual systems. The perfection in term of administration and economical in phrase of speeds up of the intended method are accepted by the analysis.

Wi-Fi is a local area wireless networking technology that is widely used for different purposes such as data transmission and wireless communication. Wi-Fi connection will most often result in faster, more reliable internet access and it is cheap. A penetration test on Wi-Fi is a proactive and authorized attempt to evaluate the security of an IT infrastructure by safely attempting to exploit system vulnerabilities, including OS, service and application flaws, improper configurations, and even risky end-user behaviour. Several operating system distributions like Kali Linux, pentoo are taken to the penetration testing. These systems require highly skilled technical users. In this paper, we are explaining methodology of combing all tools and methods and implementing them as a mobile application, making it feasible for anyone to do penetration testing of available Wi-Fi networks easily. The application will include test cases that are subjected to both an application and network layer penetration test. The advantage of this approach is android development requires minimal investment as Android provides freely its software development kit (SDK) to the developer which minimizes the development and licensing costs. Unlike other mobile platforms, Android application can be deployed in different ways. Usage of such systems eliminates need of having deep knowledge about networks and security aspects as it provides comparatively easy to use techniques but with the same effectiveness as of conventional tools.

In wireless sensor network or mobile ad-hoc network, numbers of sensor or mobile nodes are present that communicate with each other. The data is exchanged between these nodes, for this many routing algorithms are used that determine the path, distance etc. of the network. The process of finding the path between the nodes for information transfer is termed as routing. As per literature studied it was concluded that the most of the routing protocols such as AODV, DSDV, DSR etc. do not focus on the security of network. As per comparison, AODV routing protocol is better than the other protocols on the basis of performance metrics like throughput, PDR, packet loss etc. The security is one of the key factors that should be considered while transferring the information. Traditional protocols work on the basis of the distances between the nodes, trust value, bandwidth, and throughput etc. Security of the data was not considered anywhere. So in this work, a new algorithm is proposed that will take security of the data in account along with it the trust mechanism approach is updated. On the basis of both direct and indirect trust values, node to node distance is calculated. After finding the route, the security of the data is maintained by introducing key concept. This encryption of data before sending it to the destination prevents it from unauthorized access. From the results obtained it is concluded that this proposed algorithm is efficient than the traditional routing algorithms as the security of the network is increased. So we can say that this paper improved the security of AODV routing protocol with trust calculation and key concept.

Relational modelling is used for the modelling of transactional data in relational databases while dimensional modelling is normally used for the modelling of dimensional data in data warehouses. In relational modelling the attention is on identification of fundamental or strong entities involved in the execution of business transactions, while in dimensional modelling it is on classification of associative entities that bring business measures.[1] Dimensional modeling is a database design practice developed specifically for designing data warehouses. Its objectives are to create database structures that end users can easily understand and write queries against, and to optimize query performance. It has become the leading approach to designing data warehouses in practice and has proven to be a major breach in developing databases that can be used directly by end users. Dimensional modeling is not based on any theory, but has clearly been very unbeaten in practice.[2]
