Inductive Wireless Power Transfer Charging for Electric Vehicles–A Review

Abstract: Considering a future scenario in which a driverless Electric Vehicle (EV) needs an automatic charging system without human intervention. In this regard, there is a requirement for a fully automatable, fast, safe, cost-effective, and reliable charging infrastructure that provides a profitable business model and fast adoption in the electrified transportation systems. These qualities can be comprehended through wireless charging systems. Wireless Power Transfer (WPT) is a futuristic technology with the advantage of flexibility, convenience, safety, and the capability of becoming fully automated. In WPT methods resonant inductive wireless charging has to gain more attention compared to other wireless power transfer methods due to high efficiency and easy maintenance. This literature presents a review of the status of Resonant Inductive Wireless Power Transfer Charging technology also highlighting the present status and its future of the wireless EV market. First, the paper delivers a brief history throw lights on wireless charging methods, highlighting the pros and cons. Then, the paper aids a comparative review of different type’s inductive pads, rails, and compensations technologies done so far. The static and dynamic charging techniques and their characteristics are also illustrated. The role and importance of power electronics and converter types used in various applications are discussed. The batteries and their management systems as well as various problems involved in WPT are also addressed. Different trades like cyber security economic effects, health and safety, foreign object detection, and the effect and impact on the distribution grid are explored. Prospects and challenges involved in wireless charging systems are also highlighting in this work. We believe that this work could help further the research and development of WPT systems.

Examining the prediction of reading comprehension on different multiple‐choice tests

Abstract: In this study, 180 Norwegian fifth-grade students with a mean age of 10.5 years were administered measures of word recognition skills, strategic text processing, reading motivation and working memory. Six months later, the same students were given three different multiple-choice reading comprehension measures. Based on three forced-order hierarchical multiple regression analyses, results indicated that the unique contribution of measured skills and processes to performance varied across comprehension tests. In particular, when the test consisted of a longer passage, contained a larger proportion of inferential questions and was answered without access to relevant text passages, the relative importance of word recognition skills seemed to be reduced while working memory emerged as a relatively strong, unique positive predictor of comprehension performance. These findings have important practical implications for the assessment of reading comprehension.

DevSecOps: A Multivocal Literature Review

Abstract: Involving security in DevOps has been a challenge because traditional security methods have been unable to keep up with DevOps’ agility and speed. DevSecOps is the movement that works on developing and integrating modernized security methods that can keep up with DevOps. This study is meant to give an overview of what DevSecOps is, what implementing DevSecOps means, the benefits gained from DevSecOps and the challenges an organization faces when doing so. To that end, we conducted a multivocal literature review, where we reviewed a selection of grey literature. We found that implementing security that can keep up with DevOps is a challenge, but it can gain great benefits if done correctly.
