Energy efficiency has become an increasingly important concern in data centers because of issues associated with energy consumption, such as capital costs, operating expenses, and environmental impact. While energy loss due to suboptimal use of facilities and non-IT equipment has largely been reduced through the use of best-practice technologies, addressing energy wastage in IT equipment still ...

Iran is a developing country with a population of over 80 million. The total daily MSWs production in Iran is about 50 million kg. Most of the MSWs in this country is being disposed of in the landfills. Some of the landfills are located in the urban area or near to sea, river, and forest. In this regard, the management of MSWS becomes a concern in Iran. One solution to manage MSWs and mitigate ...

The impending energy and natural resource crisis forces us to research innovative ways of optimizing our resource consumption. Recent studies have shown that a better understanding of an individual’s energy consumption helps people to lower their energy footprint significantly. We propose SPOTLIGHT, a system that profiles an individual's natural resource consumption pattern in real time using w...

To tackle the dilemma of supporting broadband, high-speed wireless access or well utilizing narrow, non-contiguous spectral resource, Long Term Evolution-Advanced (LTE-A) employs carrier aggregation. It combines different component carriers to send data to users in high rates. Many LTE-A downlink resource scheduling methods seek to assign component carriers or resource blocks to improve through...

Since more than 10 years energy efficiency is a well discussed research topic in computer science. Because the immediate consumers of energy are hardware resources, these resources have been subject to optimization in the first place. But hardware is in turn used by software, running on top of it. Software offers the interface to the end-user and thus allows to correlate the utility of end user...

Renewable energy provides twenty percent of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It is a renewable source of energy and provides almost one-fifth of electricity in the world. Also, it generates electricity using a renewable natural resource and accounting for six percent of worldwide energy supply or about fifteen percent of th...
