作者： A Inba Rexy J S Nancy Mary K G Priyaadarshini Therese Rachael Department of Electrical and Electronics Engineering Loyola-ICAM College of Engineering and Technology Chennai India Master of Science in Electrical Engineering and Embedded Systems Hochschule Ravensburg-Weingarten Germany Robert Bosch Engineering And Business Solutions Pvt Ltd Coimbatore India

The aim of this paper is to boost the power output of the hybrid energy harvester effectively and to provide electrical optimization for a hybrid energy harvesting system that produces two electrical outputs from a single source of mechanical input namely vibration. Two different electrical outputs are produced by using the concept of piezoelectricity and electromagnetic induction. In this paper, an electrical equivalent is obtained for the standalone piezoelectric system and the electromagnetic system. The rectification of the piezoelectric system along with its results is discussed. Different circuits for amplification is studied and simulated to improve the voltage. All the practical experimental outputs and the different software used to gain these outputs are recorded. The various applications of the hybrid system are reviewed and discussed.

Utilizing the vast amounts of data acquired by sensor networks set up in various businesses is the foundation of smart supply chain services. When it comes to exchanging data, Sensing as a Service (S2aaS) is an intriguing pattern of IoT business models. Data security, performance, privacy, and single point of failure are just a few of the reasons why the present centralized Internet of Things (IoT) S2aaS models aren’t cut out for IoT large data sharing. We present a decentralized framework for IoT S2aaS for smart supply chains that is based on blockchain technology. Without the need for intermediaries, this framework may ensure that data consumers can safely communicate data with data owners of IoT solutions while retaining full ownership of their data. Researchers lay out the framework’s layered architecture and system model, from which derive a specific plan for implementing IoT S2aaS through the usage of smart contracts. We put an Ethereum-based software prototype into action. The outcomes of the experiments prove that our solution is both valid and effective.

This paper presents different PHP-based frameworks used for building robust, enterprise-level web applications. The paper focuses on the main features of the two frameworks, and then analyze some of the advantages and disadvantages of using each of them. DotKernel is a custom concept built by Apidemia, mainly used internally but present in the open-source environment. It is a collection of middleware applications built on top of the Zend Expressive microframework, implementing customized versions of some of the Zend Framework components. Symfony is also a concept consisting of a web application framework, a set of reusable, heavily used PHP components, and a community sharing a common philosophy.

Point of Sale systems have been rapidly getting advanced and powerful. In recent times, we can see credit and debit card based POS systems apart from traditional cash POS with manual entry. POS systems with Barcode readers are also developed. What we must recognize is that still many fraud and security issues are present. POS system that we have proposed, is based on new age technology that is `AI subset based POS' which is a new method. We can find POS system with face recognition and Card swipe system at few places. Considering that the security problems still exists with the current system. We have proposed face recognition along with password as a method of payment making POS systems both card less and cashless. Cloud Computing technology is suggested way of implementation to make solution overall energy efficient as well.

Traffic congestion is one of the major problems in most of the cities across the globe and it leads to several other problems like pollution, time wastage, long traffic queues on roads and may cause accidents. Improvement of Road infrastructure is not always the feasible solution to resolve the problem. In real life scenario shorter distance route towards the destination attracts majority of people and at times it may aggravate traffic jam conditions. Therefore, a real time traffic information for intelligent decision making to decide the route preference is required. Moreover, a system which considers the factor of distance towards the destination along with real time traffic situation on that route will add to the solution to the congestion problem. certain parameters such as distance, weather condition, road location, day of week and time are considered to formulate the problem and to find solutions to these problems This paper outlines a combination of logistic regression with fuzzy logic such that a smart decision to preferred path can be taken. It is used to compute the probability of each possible path by considering the real time traffic information, distance and road condition and later is used to take decisions in an uncertain scenario. Proposed Method considers the number of parameters like distance, weather condition, road location, day of week and time. © 2018 The Authors. Published by Elsevier Ltd.

The goal of this paper is to find out what are the steps in developing an application, the difficulty of it and future improvements. With this occasion, we chose to develop a weather application. A weather application is a very handy one, with daily usability and can be constantly updated to fit certain needs. Many people now rely on data directly from their smartphones and the weather forecast is something indispensable to have. The most commonly used development environment is Android Studio, the all in one developing tool which ensures full control on the application development.

In recent years, large-scale urbanisation has been on the rise with cities being the hubs for growth, but rural business continues to play an important role in any country's overall development. A recent report reveals that almost 69 percent of India's population resides in their villages, accounting for almost 50 percent of the nation's GDP. This agricultural region varies from small towns with less than 500 residents to small towns. There are also similar situations in western nations. Despite their economic contribution, smaller villages seem to earn fewer in terms of infrastructural expenditure. The major problems addressed in these small towns include shortage of adequate public transit, emergency care and limited knowledge on federal subsidies for rural areas. Our vision is to expand the Smart city to Smart village by allowing use of recent technical advances and giving more attention to the problems in rural areas. The approach in this chapter is to bring IoT technology to Villages by literally showing a network of linked sensors and knowledge dissemination devices, controlling energy use and ensuring infrastructure protection. It gives a wide-ranging vision of enhancing the standard of living in villages and encourages them to meet the essential needs of domestic villagers.
