The primary operation requirement in a large area network is a query of shortest distance. Finding the shortest route from source to destination is one of the major problems faced in the network. This paper provides an implementation of solving one of the problems of finding a shortest route using a algorithm known as Genetic algorithm. Genetic algorithms are the evolutionary techniques for finding the fittest gene amongst all the combination of chromosomes using crossover and mutations over the chromosomes. The purpose is to find the most approximate solution that gives us the least distance, which is the shortest route for traversing the cities. This problem a salesman has to traverse n number of cities in such way that it gives a 'uni' directed graph and each city is visited only once. We accomplish this by carrying out the algorithm through generating a fitness formula and with the help of genetic operators like selection, crossover and mutation.

Cloud computing is an internet oriented memory space that data can be fetched through internet. In recent years cloud computing is getting more attention because of the innovation in hardware and software resources, the ability to manage them remotely with benefits like high computing power, competitiveness, cost efficiency, scalability, flexibility, accessibility and availability, just adding more to the interest. There are many pros to cloud computing but on the other hand the security and integrity of data that gets stored in untrustworthy server is a determinant factor. Remote data integrity is playing a vital role in modern cloud storage and existing protocols are not secure enough under the quantum computer attacks. That is, attackers can hack the information sometimes from cloud even if data integrity protocols were installed. In this paper, a survey on cloud security by data integrity and auditing technique is done.

The availability of high resolution data from remote sensing satellites has revolutionized the process of thematic mapping and geospatial database creation, specially, in the context of urban and regional planning. Further, Geographic Information System (GIS) has emerged as a powerful tool in integrating and analyzing the various thematic layers along with attribute information to create and visualize various planning scenarios for decision making. The increasing demands in urban planning and management sectors call for integrated application of remote sensing and GIS for sustainable development of urban areas. The various thematic layers (land use pattern, road network, water supply, solid waste disposal, soil map, ground water potential map, etc) can be generated which is then integrated with socio-economic and demographic data of the city to model the urban growth of the city. The present work is trying to emphasise the importance of geo spatial data in urban studies and to accentuate the future of applications of geo-spatial data in urban studies.

This paper showcases use of the principle of piezoelectricity to harvest energy through pedestrians' footsteps and collect data about pedestrians like locomotion pattern and tracking. The configuration of piezoelectric material underneath a plywood panel allows it to be interconnected to cover an area of any given size and shape. These interconnected panels help visualize the area as an array of panels and view information about presence of a pedestrian, locomotion pattern and pattern prediction, as well as to control the state of a variable. This pedestrian locomotion pattern data can be used for making decisions about designing a floor layout at railway stations, airports, similar public places, and for product placements in shops, malls and supermarkets. The energy generated can be used to power up streetlights, public Wi-Fis and helps in contributing towards generating more renewable energy, as non-renewable energy resources are plummeting and it may not be possible to harness solar or hydro power at all times.

The paper consists of Ammonia leak detection algorithm which is an application. It based on PIC microcontroller using electrochemical sensor. Running a large scale industry, safety of worker and equipment is on first priority. When an industry specially runs in risky chemicals such as production of ammonia or use of ammonia as secondary chemical, it is a need to set up a safety system inside the industry. So to overcome this problem, here is a simple and low cost solution is provided. NH4-NH3 is a one of the simple and useful gas sensor widely used in chemical industries. By adhering to industry standards for size and connection orientation, the NE4-NH3 can be retrofitted easily to existing product designs. By using PIC microcontroller the leakage of gas is analyzed and processed for implementing an alarm system. Main purpose of this system is to provide safety of an industrial environment. The leakage detection and ECS algorithms proposed here are applied to the methodology, and the collected concentration data is analyzed. A detection rate of 99.8% is achieved, with 3 alarms recorded over 7 days, and an average detection delay of 800 msec.

Existing conventional modes of transportation of peoples consists of four unique types: rail, road, water and air. These modes of transport tend to be either relatively slow (e.g., road and water), expensive (e.g., air), or combination of both (e.g., rail). Hyperloop is a new mode of transport that seeks to change this paradigm by being both fast and inexpensive for peoples and goods. Hyperloop is also unique in that it is an open design concept, similar to Linux. Feedback is desired from the community that can help advance the Hyperloop design and bring it from concept to reality. Hyperloop consist of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube.

Rapid urbanization and industrialization cause a lot of infrastructure development is taking place in the last two decades. Due to this process, it leads a big problem. There are so many shortages of construction materials, increasing of wastes and other products. All the waste products have to be recycled in order to create a balance between production and disposal of wastes. The other alternative uses found are to use waste plastics in the Construction Industry. In this project we used the waste plastics in Cement Concrete construction. Standard Mix ratio for framed and unframed structure is M20, since it gives maximum strength to the structure to bear the Loads. Plastics are used in various ways for our project used as modifier. Plastics are added in the percentage of 2%, 4%, 6%, etc…, for the replacement of cement and sand. Many tests were conducted for the materials and determine their physical and mechanical properties. From those results Experimental investigations comprised of testing for physical requirements of Course Aggregates (CA), Fine Aggregates (FA), cement and the modifier. From that result the replacement content was 6% and the strength was found to be twice than plain cement concrete. While using modifier in rigid concrete pavement, it leads to decrease in size of the elements.

In a country like India, where population is growing rapidly with development of the nation, this is resulting in lack of space ultimately asking for tall structures in order to create space for every individual. Some parts of India are under seismic zone V, which needs utmost care and safety, thus there is a need of lateral load resisting members in a tall structures. In this study we are analyzing a G+12 tall structure, considering seismic zone V (response spectrum method) with soft soil condition, for analysis and modelling, ETABS'17 is used. Here we are considering infill masonry wall frame and steel bracing system frame for comparison. The steel bracing system and Infill masonry in reinforced concrete frames is viable for resisting lateral forces, steel bracing is easy to erect occupies less space and has flexibility in design for meeting the required strength and stiffness whereas Infill masonry is easy to assign with unskilled labors. In this comparative study, it is concluded that Steel bracing at exterior shows desirable stability than other cases in terms of resisting forces and moment. Also, in terms of cost effectiveness steel bracing system is quite suitable for lateral load resisting whereas Infill masonry structure is second alternate whereas bare frame case shows worst result. Therefore, it can be justifying that steel bracing frame is overall more stable than bare frame.
