The commitment to improve energy and environmental performance in public administration(PA)is essential for the success of development models geared towards lasting sustainability.The PA has a dual consumer/user role,...
This paper makes a technical analysis of the methods to increase the energy efficiency of washing machines for student education.Starting from the definition given by the Energy Efficiency Index,the present analysis p...
The maximum power point of PV (photovoltaic) generation moves depending on weather conditions and load. Therefore, it is significant to make sure that the panels can work at the maximum power point under MPPT (maxi...
Antioxidant efficiency was studied in fresh edible algae: Cladophora, Microspara and Nostochopsis spp. from Nan River, Nan province. The samples were collected from Pua and Tha-Wang-Pha district, studied antioxidant ...
This paper presents an overview of the safety performance of the major existing pipeline transmission system in Canada, USA and Europe. The article deals the experience of Georgia in the development of pipeline transp...
The price of fuel oil continues to rise, decreased supplies oil at the other side, both factors increase the interest of researchers to conduct research related to fuel efficiency. Therefore the aim of this study is t...
This study presents the modeling of a parabolic trough solar collector. The main objective is to show the influences of the parabolic trough sensor effective efficiency (concentrator optical efflciencies of transmiss...
The conventional P & O (perturb-and-observe) method, which is the most widely used as MPPT (maximum power point tracking) control, has the problem of low efficiency and unstable operation when solar radiation cha...
Natural energy use is important to reduce the energy consumption of buildings. However, further reducing energy consumption with traditional systems is difficult. Therefore, we proposed a MMHP (multi-source and multi...
This paper presents some opportunities to improve feedwater system efficiency for industrial boilers, usually consisting of multistage centrifugal pumps driven by three-phase induction motors. There is abundant litera...
