Comparing Web Accessibility between Major Retailers and Novelties for E-CommerceXu, Jinmeng January 2020 (has links)
Purpose –Comparing the accessibility of e-commerce for General Merchandise, between major retailers and novelties, in the conformance of web accessibility guidelines, and the implementation of rich internet applications specifications. So that to figure out whether the differences exist between them, if so, what are the differences, and analyzing upcoming e-commerce and established e-commerce. Method – The descriptive and quantitative case studies were used to evaluated 45 websites respectively from major retailers and novelties in General Merchandise of e-commerce, where sample websites were selected from Alexa’s rank lists. Then the WAVE tool, Accessibility Quantitative Metric (WAQM), and Fona assessment were applied for analyzing cases for representing the accessibilities and answering the research questions of purpose. Findings – ARIA specifications as a kind of technological solution really had positive functions on web accessibility when only focusing on accessibility guidelines, because the novelty websites with less ARIA attributes resulting in lower accessibility levels generally, even though there were also many other elements that can affect accessibility. Implications – In the main branch of General Merchandise, the degree of web accessibility in major retailer websites was better than that in novelties, which means as far as e-commerce is concerned, the accessibility of mature websites that had been established for a long time was contemporarily stronger than that of new websites with creative products. Limitations – From the perspective of the sample, there were limitations in sample sources, size, websites languages, while in the technical aspect, the evaluation of dynamic contents just aims at keyboard navigation, and the tool of Fona assessment also had restrictions.

Development of a Cost-Effective, Reliable and Versatile Monitoring System for Solar Power Installations in Developing Countries : A Minor Field Study as a Master Thesis of the Master Programme in Engineering Physics, Electrical EngineeringTrella, Fredrik, Paakkonen, Nils January 2016 (has links)
This report is the result of a conducted Minor Field Study (MFS), to the greatestextent funded by the Swedish International Development Cooperation Agency(SIDA), in an attempt to design a system for evaluating smaller solar power systems indeveloping countries. The study was to the greater part conducted in Nairobi, Kenyain close collaboration with the University of Nairobi. The aim was to develop asystem that would use easily available components and keep the costs to a minimum,yet deliver adequate performance. The system would measure certain parameters of asolar power system and also relevant environmental data in order to evaluate theperformance of the system. Due to the specific competence of the collaboratinggroup at the University of Nairobi, a Kinetis Freescale K64-microcontroller with anARM-Cortex processor was selected as the core of the design. Components wereselected, schematics were drawn, a circuit board was designed and manufactured andsoftware was written. After 12 weeks a somewhat satisfying proof-of-concept wasreached at the end of the field study in Kenya. The project however proved howdifficult it is to go from first idea to a functional proof-of-concept during a limitedtimeframe, and also in an East-African country. The final proof-of-concept was testedat Mpala Research Centre in Kenya and despite containing some flaws proved that itwould indeed be possible to design a working system on the principles discussed inthis report. The system is open-source, so anyone may use and modify it.
