 Abstract

India is a fast growing developing country consisting of large city population in many numbers. Along with increase in population generation of waste is highly proportional. Management of these rejects in a sustainable procedure without harming the neighbours is very important. Bengaluru City generates about 4000 metric tonnes per day of MSW within the jurisdiction of Bruhat Bangalore Mahanagara Palike (BBMP), which is responsible to provide and administer the urban infrastructure and other civic amenities of the Greater Bengaluru Metropolitan area having a population of over 10 million. Handling and management of this huge quantity of municipal waste is a challenge for the urban local body (ULB) about environmental, social and techno-financial aspects. The paper consists of proposing a method of controlling the odour produced in the solid waste treatment plant especially for the wet solid waste along with increasing the rate of composting in a conventional manner. It also included to determine the causes of malodours, to identify the most common odorants in municipal waste, properties they consist, how they can be affected and ways to prevent them to the maximum magnitude. The solution is under testing so it cannot with certainty be determined if the suggestions will reduce or prevent emission of odour. After studying recent research papers, the method proposed in this project would be an efficient suggestion and could be implemented with ease even if it is required to change the current treatment procedure of the municipal solid waste management plants of the city. Odour emission could be regulated by avoiding the turning operation and maintaining the factors affecting composting within the permissible limits. This can be done by maintain the required temperature, moisture content by the principle of transfer of heat and aeration within the pile from the method proposed.

 Abstract

Fog is a big reason for road accidents. Images which are captured under bad weather conditions suffer low contrast so as their quality also degrade with the changes in atmosphere. The main reason behind this problem is that, the light capture by the lens is spread by the atmosphere. Fog reduces visibility to less than 1 kilometre. This paper aims to resolve the sight problem faced by car/other automobile drivers when driving in foggy weather condition and at night. For improving the visibility level of an image and reducing fog, various image enhancement methods are used. For improving the visibility level five major steps are used. First step is acquisition process of foggy / dark images. Second is estimation process. Third is enhancement process (improve visibility level, reduce fog). Next process is restoration process (restore enhanced image) while the final is the vehicle detection. The main aim of the paper is to review image enhancement and restoration methods for improving the quality and visibility level of an image which provide clear image in bad weather condition.

 Abstract

In this study, seismic analysis of tall R.C. buildings has been carried out by considering rigid and flexible slabs. Etabs software is used for the analysis purpose. In this software 3 options are provided to account for rigid and flexible slab assumption viz Rigid (Membrane), Flexible (Shell-Thin) and Flexible (Shell-Thick). Static analysis (equivalent lateral force method) and dynamic analysis (response spectrum method) are used for the analysis of 30 storey framed building. Comparative study is done between 3 types of slabs as mentioned above and results are obtained in terms of modal periods, modal frequencies, displacement, drift and stiffness for all seismic zones viz V, IV, III and II.

 Abstract

Theflexibleuseofcreditanddebitcard transactions has become increasingly ubiquitous and so have the associated vulnerabilities that make them a common target for cyber criminals. Furthermore, a prevalent complication associated with blocking of ATM cards involves tedious interactive processes and even possibly long waiting times during interaction with customer care services. Using a three factor authentication scheme employing RFID Involving One- time password, we describe and quantify the potential to overcome common transaction liabilities (brute force attack, shoulder surfing, skimming of ATM cards, etc.). The auxiliary feature of blocking ATM cards is implemented using a QR code authentication scheme and RFID technology. The proposed system, therefore, ensures both secure usage of ATM cards and cost effectiveness by utility of novel and increasingly common technology, when also simultaneously proving to be user friendly.

 Abstract

As a universal truth, concrete is weak in tension, it has less ductile property and little resistance to cracking. Hence Fiber Reinforced Concrete is being used popularly against PCC (Plain cement concrete) which gives more ductility, resistance to cracking and strengthening of concrete. Due to the richer flexural strength property of fiber reinforced concrete, it can act as crack arrester.An attempt is made in this dissertation work to investigate experimentally the performance of fiber reinforced concrete with regard to compressive strength and flexural strength by varying the percentage of steel fibers. The percentage variation of steel fiber from 0%, 1%, 2%, 3% and 4% by weight of concrete is added in the designed mix concrete of M-25 grade. The type of Steel fiber used is of hooked end of aspect ratio 66.67. The cubes and prism were cured for 7, 14 and 28 days and tested to understand the compressive strength and flexural strength. Model RCC (Reinforced cement concrete ) beams of 700X150X150mm with nominal longitudinal reinforcement and shear reinforcement with a layer of steel fiber provided at 5cm from bottom of beam unidirectional with varying percentages of steel fibers (0% to 4%) were cast and cured for 28 days. The beams were tested under two point loading system and load deflection characteristics are recorded. It is observed that the beams having a layer at 5cm level have shown excellent ductility characteristics giving sufficient warning before complete failure.

 Abstract

Processing of geospatial data is compute intensive. If this processing is done on a large scale which has huge data sets like OpenStreetMap then the process of running a filter and the process of aggregation operations on huge records of data can be benefited by performing parallel processing on massive parallel processing platforms. The focus of the project is to describe and build a distributed geospatial processing framework based on one of the evaluated open source stream and batch processing engines like Apache Hadoop, Spark and Pachyderm to perform Spatial ETL functionalities which Extract, Transform and Load like extraction of data from different data sources, transformation of data to correct errors, cleanse, fuse, make them compliant to defined standards and load the transformed data into target spatial database (postgresql) or GIS file or Geospatial web services.

 Abstract

Cash may no more lead the market of all sense. Debit cards, e- wallets and other digital platforms are witnessing a sweep in volumes. But are we fully equipped to switch to a cash less economy?Everyone from the petty shopkeeperto the chai wala are embracing digital payment to tide over the cash crunch. While we are waiting in the long queues at ATMs to preter out and notesof 100,500 & 2000 denomination to become accessible again, the adoption of digital payment solutions is picking up at a furious pace.ET Wealth conducted an online survey to find out the level of adoption of digital payment solutions and user habits. The findings reveal that while people are getting comfortable with cashless payments, some mindset issues are holding back many from adopting the newer platforms. The findings also suggest that the usage habits of those who have taken to cashless modes could be exposing them to security threats.
