E-WASTE and Environmental Impacts of Computer Hardware Electronic Waste (E-waste) is a generic term embracing various forms of electric and electronic equipment that is loosely discarded‚ surplus‚ obsolete‚ or broken. When e-waste is improperly discarded as trash‚ there are predictable negative impacts on environment and human health. E-Waste is a popular‚ informal name for discarded electronic products‚ such as computers‚ VCRs‚ and cameras‚ which have reached the end of their useful life. Discarded

been made‚ such as cell phones. The power grid however has not stayed current with what technology has to offer. Resolving the gap between the existing grid and the smart grid is an area of fervent research. Much of the success of the smart grid relies on new communication architecture to allow for smart metering‚ quality of service implementations‚ and distributed power generation. In a way there is an opportunity not just to incrementally change the grid‚ but to architect it intelligently for current

These days "cloud computing" is the buzzword used to describe the direction in which information network infrastructure seems to be leaning towards. The authors reasoned that cloud computing sprouted from grid computing‚ distributed computing‚ and parallel computing‚ which resonated with the works of Foster‚ Zhao‚ Raicu‚ & Lu‚ 2008 [1]. And like many‚ they found it a challenge to provide an encompassing definition for cloud computing. Foster et al. defined cloud computing as‚ “A large-scale distributed

increasing demand of Distributed Generation (DG) systems either connected to the grid through some power electronics grid-tie inverters or to work in isolated (microgrid) mode towards the development of a smart grid network. In this paper a technical review of Integration of Unified Power Quality Conditioner (UPQC) in Distributed Generation Network has been presented. Though the primary task of UPQC is to minimize the grid voltage and load current disturbance along with the reactive and harmonic power

Discussion Question 1. Briefly describe Moore law. What are the implications of this law? Are there any practical limitations to Moore law? Moore’s Law is a hypothesis stating that transistor densities on a single chip double every two years. Moore ’s law describes a long-term trend in the history of computing hardware. The number of transistors that can be placed inexpensively on an integrated circuit has doubled approximately every two years. Moore ’s law is a rule of thumb in the computer

SCADA Vulnerabilities and Electric Power Industry Abstract Electricity is an essential element of life in the United States. It is crucial to manufacturing‚ business companies‚ residences‚ and certain methods of shipping. A deficiency in electricity can not only cause trouble‚ but also financial loss due to reduced business and manufacturing production. This paper will look at the basic concepts of SCADA (Supervisory Control and Data Acquisition) systems‚ their vulnerabilities in regards
