This article is intended to design an automated device for power line quality and life test. The designs of this device contain three various parts: mechanical system, control and PC software. The control algorithm and the program execution flow will be described in detail in this paper. Using the raspberry pi to control the step motor and to realize the switch of machine on and off is the main purpose...
In this paper it is described the prototyping of an instrumented chair that allows to fully-automate the “Timed Up and Go”, the “30-Second Chair Stand” and the “Hand-Force ” tests assessment. The presented functional chair prototype is a low cost approach that uses inexpensive sensors and the Arduino platform as the data acquisition board, with its software developed in LabVIEW. The “Timed up and...
Elevators are used as main connectivity unit of the floors, in malls, offices, industries and, buildings of the hospital. Generally, the chip based controllers are used to control the working of the elevator system. These controllers have some sharp specifications which cannot be maintained at all the time and, that's why faults occur from time to time. So, Programmable Logic Controller (PLC) is implemented...
Many robotic systems have been developed to provide assistance to individuals with disabilities. Most of these systems require the individual to interact with the robot via a joystick or keypad, though some utilize techniques such as speech recognition or selection of objects with a laser pointer. In this paper, we describe a prototype system using a novel method of interaction with an assistive robot...
Testing of current devices in the automation domain cannot be done mathematically exhaustive due to the huge number of possible test cases and, even more important, the tremendous amount of time for the execution of all test cases.Thus, a dramatic reduction is needed in the testing domain.This paper discusses two possibilities for the reduction of test case execution time by reducing the number of...
Building information modelling (BIM) is only a tool in the procurement of a building, but it is changing the way the whole process is undertaken. Having a single model which is used by all disciplines requires a different management structure and by consequence a restructuring of the resources required to complete a project.These changes are encompassed in Integrated Practice and more recently Integrated...
Applications of 3 dimensional (3-D) virtual reality are now possible on current mobile phones due to the advances in mobile 3-D graphics technologies. However, the user-interface to these applications is generally still limited to the basic phone keypad which detracts from the sophisticated experience 3-D worlds can provide. In this paper we present a solution to this problem which utilizes the accelerometers...
Multi-core SoC created great opportunities to increase overall system performance while keeping the power in check but also created many design challenges that designers must now overcome. The challenge of doubling performance every two years used to drive superscalar design with more functional units running concurrently or deeper pipeline racing for highest frequency at the cost of higher power...
An organizational level test strategy needs to incorporate metrics to make the testing activities visible and available to process improvements. The majority of testing measurements that are done are based on faults found in the test execution phase. In contrast, this paper investigates metrics to support software test planning and test design processes. We have assembled metrics in these two process...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
