Egocentric Vision for Dog Behavioral Analysis

Abstract: Egocentric vision, an offshoot of computer vision, offers unique insight into the visual world by examining images and videos taken by a digital camera This research, with the aid of ecocentered view, describes the actions of the different dog breed in different situations It will improve predicting the breed behavior of the dog and gaining more knowledge of the breed of dog To understand the breed behavior of the dog is to evaluate the historical breed data of the dog with current data The comparison between dog’s current situation and dog’s activities will predict behavior in indoor and outdoor situations

Design and Implementation of Automated Solar/Fuel Cell Power Controller for Hybrid Electric Vehicle

Abstract: With an ever increasing demand for energy for transportation and alarmingly high levels of pollution caused due to excessive consumption of fossil fuels, the Research & Development in Electric/Hybrid Electric Vehicles is be- ing carried out at an accelerated pace. The success of any of the above approaches will depend on the capabili- ties of the batteries i.e., power density, cost, maintenance and life span etc. This paper proposes a novel, flexible strategy for Multi Objective Control of Power Controller (MOPC) for a Hybrid Electric Vehicle (HEV). Here a new control strategy has been implemented with three different configurations like Constant Fuel Cell Current Mode, Constant Battery Current mode and Constant Battery Voltage Mode. Based on the load demand on the vehicle, control strategy is automatically selected for propulsion or charging purposes, by using computer and interfacing circuits.

Eloa Beside Vampire Attacks In Wireless Sensor Networks

Abstract: Wireless Sensor Networks in today’s world are the basic means of communication. An ad hoc network is a group of wireless nodes, in which each node can communicate over multihop paths to any other node without the help of any preexisting infrastructure such as base station or access points. Owing to these feature ad hoc low power wireless networks are capable of sensory and pervasive computing which forms the wireless ad hoc sensor network. The limitations of system are resources like battery power, communication range and processing capabilities. One of the major challenges in Wireless Sensor Networks is the security concerns. The attacks affecting these systems are increasing as they progress. One of the resource depletion attacks called vampire attacks are the major concern. They not only affect a single node but they bring down the entire system draining the power i.e. Battery power. In this paper, the system proposed overcomes this challenge by using the Energy load observing Algorithm (ELOA) and the energy consumption is reduced to a great-extend.

Green Electronics Design: Curriculum, Content, and Learning for Engineering

Abstract: Energy consumption, material application, packaging, and recyclability are the major areas to be considered for greener electronic products with reduced environmental effects and increased eco-efficiency. Design for green electronics includes lead-free solders, conductive adhesives, environmentally friendly packaging and design technologies, LCA and assessment, life cycle cost analysis, and data management. Engineering graduates should be taught sustainability, its principles, and how these principles can be incorporated into the design and manufacturing processes. Engineering students have to be exposed to design for the environment, directives, environmental law, technology, waste management, and electronic waste recycling. This paper gives introduction to green electronics, sustainability principles, curriculum, and content, teaching, and learning methods needed for green electronics. This paper analyzes the content necessary and the methods for educating the engineers for sustainability, problem solving, and the skills required. This paper enlightens the reader of the content, skills, and the design methods for sustainable engineering.
