An intelligent and secure system for predicting and preventing Zika virus outbreak using Fog computing

Zika virus is a mosquito-borne disease that spreads very quickly in different parts of the world. In this article, we proposed a system to prevent and control the spread of Zika virus disease using integration of Fog computing, cloud computing, mobile phones and the Internet of things (IoT)-based sensor devices. Fog computing is used as an intermediary layer between the cloud and end users to reduce the latency time and extra communication cost that is usually found high in cloud-based systems. A fuzzy k-nearest neighbour is used to diagnose the possibly infected users, and Google map web service is used to provide the geographic positioning system (GPS)-based risk assessment to prevent the outbreak. It is used to represent each Zika virus (ZikaV)-infected user, mosquito-dense sites and breeding sites on the Google map that help the government healthcare authorities to control such risk-prone areas effectively and efficiently. The proposed system is deployed on Amazon EC2 cloud to evaluate its performance and accuracy using data set for 2 million users. Our system provides high accuracy of 94.5% for initial diagnosis of different users according to their symptoms and appropriate GPS-based risk assessment.

基于模糊优选模型的输变电工程造价管理成效评价研究

输变电工程造价管理对于电网投资效益具有重要的意义.目前对输变电工程造价管理工作成效的评价往往依靠主观判断,缺乏一种客观、准确的评价方法,为此,本文针对输变电工程造价管理成效开展评价研究.首先运用德尔菲法、层次分析法分析输变电工程造价管理的影响因素,建立综合评价指标;其次,基于模糊优选模型建立造价管理成效评价模型;最后,...     

基于学科发展的高校科技成果转化模糊决策评价方法研究

高校科技成果转化是国家战略重要组成部分,是促进国家和区域经济发展的重要源泉,然而其评价因素仍然多局限于科技成果转化本身,并没有从学科发展这一大学建设的核心的视角开展研究,无法使得高校科技成果转化真正与高校自身发展完全融合,形成高校科技成果转化形成内生动力。本文运用模糊决策方法对高校科技成果转化开展综合评价研究,基于学科发展的视角开展分析研究,合理选取评价因素,最后开展实证研究,为形成具有实效的高校科技成果转化机制,促进科技与经济有效融合提供重要的借鉴。

From innovation to market entry: a strategic management model for new technologies

In this paper, we introduce a new framework that generates a list of strategic actions to support successful management of the innovation process as new technologies are taken to market. The framework links different stakeholders inside and outside the organisation to obtain an holistic view of the requirements necessary to develop the new technology. It integrates and synthesises existing frameworks into an inclusive set of guidelines. The framework is then tested in a case study located in a mid-size semiconductor organisation currently seeking new business opportunities in the emerging photovoltaic market. We conclude by reflecting on the usefulness of the model. Theoretically, the paper contributes to the literature on the management of the introduction of new technologies; practically, the framework provides a normative tool for practising managers.     

Corporate Control and the Decapitalization of Subsidiary Corporations: The Looting of the Bangor and Aroostook Railroad

John Rawls's A Theory of Justice is examined from the perspective of experimental methods in economics and complex adaptive systems simulations. This paper first discusses the justice principle selection process in Rawls's representation of it as a hypothetical experiment. This hypothetical experiment fails to satisfy reasonable experimental controls, particularly as reflects the conception of the individual it employs. The second section of the paper discusses the differences between Rawls's two conceptions of rational persons associated with his distinction between thin and full theories of the good. The third section uses his fuller conception of rational persons, life plans, and psychological laws in the third part of the book to offer an alternative view of the selection process understood as a complex adaptive system. The fourth section turns to a topic raised by this complex system approach, the status of normative reasoning in political-economic systems. The fifth section summarizes.
