Research ArticleOpen accessIn the abstractOptimized Energy Efficient Virtual Machine Placement Algorithm and Techniques for Cloud Data CentersSanjay Patel, Ramji M. MakwanaCloud computing is an internet based computing technology that provide on demand computing for end users. Normally, data centers allocation for application on statically based. But today so many data centers have a problem how to reduce energy consumption? Due to increase use of cloud services and infrastructure by various cloud providers, uses of energy day by day increase that's … …Journal of Computer Science, Vol. 12, Issue 9 · 24 Nov 2016 · 7,356 accessesView PDFCite
Review ArticleOpen accessIn the abstractArchitecture of an Ultra-Low-Power Fully Autonomous Universal Power Conditioner of Energy Harvester for Wireless Sensor Networks: A ReviewYeo Kim Heng, Md. Shabiul Islam, Susthitha Menon et al.A fully autonomous Universal Power Conditioner (UPC) that can accept energy from any micro-energy harvester (e.g., photovoltaic, thermoelectric, electromagnetic, piezoelectric etc.) is proposed. Generally, UPC removes the need of multiple optimized source specific converters. But, the proposed UPC architecture will be Ultra-Low-Power (ULP) with maximized efficiency to support the low energy levels generated by harvesting sources. This UPC uses a … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 7,782 accessesView PDFCite
Literature ReviewOpen accessIn the abstractRetrofitting the Electric Lighting and Daylighting Systems to Reduce Energy Use in Buildings: A Literature ReviewMarie-Claude Dubois, Fabio Bisegna, Niko Gentile et al.This paper presents a literature review about energy-efficient retrofit of electric lighting and daylighting systems in buildings. The review, which covers around 160 research articles, addresses the following themes: (1) retrofitting electric lighting in buildings, (2) electric lighting energy use and saving potential and (3) lighting retrofit strategies. The retrofit strategies covered in the review are: replacement of lamp, ballast … …Energy Research Journal, Vol. 6, Issue 1 · 10 Aug 2015 · 14,592 accessesView PDFCite
Review ArticleOpen accessIn the abstractArchitecture of Ultra Low Power Micro Energy Harvester Using RF Signal for Health Care Monitoring System: A ReviewFarah Fatin Zulkifli, Jahariah Sampe, Muhammad Shabiul Islam, Mohd Ambri MohamedThis research presents architecture of Ultra Low Power (ULP) Micro Energy Harvester (MEH) using Radio Frequency (RF) signal as an input. RF has many advantages compared to other ambient sources because it is not affected by changes of weather or time, does not require heat or wind exposure and it can be moved randomly within the bound of the transmission … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 7 Jul 2015 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractOverview of Certification Methodologies for Sustainable Constructions of Brazilian BuildingsVanessa Silva Pugliero, Lorenzo Campos Coiado, Lia Lorena Pimentel et al.The terms “sustainable” and “environmentally-friendly” have been used in the construction industry field as a marketing appeal. The methodology to judge in which level a building is sustainable in Brazil is incipient, without orientation and hardly ever there is a diffusion of these methods inside Brazilian territory. Almost all developed countries have their appropriate certification methodology for sustainable constructions. Some … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 25 May 2015 · 6,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Lignin Fraction Extracted from Brazilian Energy CropsDiogo José Horst, Jhon Jairo Ramírez Behainne, Pedro Paulo de Andrade Junior, Luís Filippe SerpeThis study quantifies the extraction performance and some properties of the lignin obtained from six crops with potential for generating thermal energy in Brazil. A full factorial design (22) with four replicates including two extraction methods and two particles size distributions was adopted for assessing the fraction of lignin, as well as its Higher Heating Value (HHV) and composition given … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 27 Apr 2015 · 7,581 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Vital Source of Energy for 21st Century: Review On Alkaline Fuel CellOmprakash Sahu, Suddhasatwa BasuA cell which converts the chemical energy into electric energy as eco-friendly way on the principle of electrochemical and Inverted by Sir William Grove in 1839 is known to be "fuel cell". It became a vital source of energy for the 21st Century. Different types of fuel cell are invented based on their working temperature and a type of material … …Energy Research Journal, Vol. 5, Issue 2 · 6 Jan 2015 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Various Inclusion Levels of β-Mannanase on Nutrient Digestibility in Diets Consisting of Corn, Soybean Meal and Palm Kernel Expellers Fed to Growing PigsW. B. Kwon, S. K. Park, C. Kong, B.G. KimAn experiment was conducted to determine the effects of various inclusion levels of β-mannanase on the energy and mannan digestibility in diets containing corn, Soybean Meal (SBM) and Palm Kernel Expellers (PKE) fed to growing pigs. The PKE contained 92.6% dry matter, 4,417 kcal gross energy kg-1, 4.02% ash and 31.3% mannan on an as-fed basis. Six barrows with an … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 1 · 20 Dec 2014 · 7,128 accessesView PDFCite
EditorialOpen accessIn the abstractON THE CHALLENGES OF THE USE AND INTEGRATION OF RENEWABLE ENERGY SOURCESMariano MartínOverview: Although renewable energy sources are plentiful, their availability is highly volatile in time and distributed across regions while and the processes that transform them into useful power or chemicals are underdeveloped. In this work we discuss on the scope for the use and integration of renewable energy sources and the future development of the alternatives. Energy, the sources and … …Energy Research Journal, Vol. 5, Issue 1 · 11 Sep 2014 · 7,540 accessesView PDFCite
