cockpit development has been largely due to technological achievements. The dramatic increase in the complexity of aircraft after the dawn of the jet age brought with it a greater need than ever for automation that exceeded a simple autopilot. Human factors studies in other industries, and within the military paved the way for some of the most recent technological innovations such as the glass cockpit, Heads Up Display (HUD), and other advanced panel displays. Although these systems are on the cutting
Mental workload (MWL) has been described as a hypothetical construct that is widely used in studies of human factors and various measurement techniques to evaluate equipment and work systems in terms of the workload experienced by people using them (Gopher, D. and Donchin, E. (1986)). It has been identified that by optimizing the allocations of MWL to individual, human errors can be reduced and lead to increase in system productivity (Xie and Salvendy, 2000, Moray, 1988, Gopher and Donchin, 1986)
The impact of customer advocacy on customer perceived value; written by Ying-Pin Yeh Published in The Journal of Business and Retail Management Research Vol. 8 Issue 1 October 2013, set out to research and analyze the effect of customer perceived value influences customer advocacy. Ying-Pin Yeh attempted to show the effects of customer trust, satisfaction, and perceived value in the telecom companies in Taiwan. This article attempts to prove that telecommunication business should be investing
The necessity to measure transit system performance along with its different dimensions has led to the development of a large number of quantitative performance indicators. Nevertheless, depending upon the specific indicator assessed, one can reach to different conclusions regarding performance. Furthermore, though performance and scale economies are closely related issues, they have been generally examined separately in the transit literature. There have been significant amounts of research undertaken
Usability is an important concept in human factors. ISO defines usability as the extent in which a product can be used to achieve goals with effectiveness, efficiency and satisfaction in a specified context of use. Technology should have an aspect of usability and user friendliness especially in a clinical context, so that it can reduce cases of medical errors. An information system comprises of various elements, among them is users who should have a clear understanding of their functions. Usability
Introduction Over the decade, business leaders are finding themselves managing through historic levels of complexity. This complexity stems from a different set of environmental shifts. The recent continuous increase in globalization and outsourcing ongoing technological changes, demand that business leaders should consider the impact of social media on all aspect of their organisations. The recent financial crouch and the demands for better financial managers have prompt business leaders to rethink
Inverters Operating at Low Modulation Index with Variable Power Factor Subhadeep Bhattacharya, Student Member, IEEE, Diego Mascarella, Member, IEEE, Geza Joos, Fellow, IEEE, and Jianhong Xu, Member, IEEE Abstract— Conventional three-level discontinuous pulse-width modulation (DPWM) techniques are typically employed in variable frequency drive applications to reduce inverter switching losses and provide maximum benefit for load power factor angles in the range from 30° lagging to 30° leading.

Related to expatriates’ issues, one factor that may result in this occurrence is the formal selection process of candidates. Therefore, through this essay, there will be a discussion about the practice of the traditional selection of international assignment and analysis on how the international assignment selection has been proposed to get some modifications for the later practice. In the end, there will be an implication section about what factor may still be unchanged in an international
The basis for implementing this survey is on the current academic culture at the University of Houston – Victoria campus. Teaching and the use of technological enhanced instructional methods for the use in face-to-face classes appears to be a highly discussed topic. After over-hearing a collection of snippets of faculty dialog by the water cooler, from what I gather. It appears that there is not any real consensus with the use of technology-enhanced instruction and increasing students learning outcomes
variables (concept indicators and coping strategies). We also applied the correlation analysis (Pearson) to find correlations between the concept and the coping strategies. To reveal the specific structures of the coping strategies in groups the factor analysis was used (Principal Component Analysis with Varimax rotation). 2.6. Procedure Data were collected in each of the cultural groups by using a simple instrument (a pencil and paper). Researchers provided questionnaires to the candidates; the
