introduction activated sludge process is one of the most common methods used in wastewater treatment plants. regarding the large volume of sludge obtained from such biological wastewater treatment processes and considerable costs of its treatment and disposal, extensive research has been and is being done on novel effective methods of sludge stabilization. in previous investigations research gr...
This paper presents an energy management strategy to supply residential load by hybrid fuel cell power plant (FCPP). Economical fuel cell (FC) model includes thermal load, local electrical load, operational cost, startup cost and different tariffs on electricity during the day hour is discussed. Several Strategies have been presented for supplying residential load (electrical and thermal loads...
electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward (c3h4) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of methylacetylene (c3h4) the pristine nanotubes is a bout -1.78kcal/mol. but when nanotube have been doped with si and al atomes, the adsorption energy of methylacetyle...
electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward hydroquinone (c6h4(oh)2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g(d) level, and it was found that the adsorption energy (ead) of hydroquinone on the pristine nanotube is a bout -7.77kcal/mol. but when nanotubes have been doped with si and al atomes, the adsorption energy of hy...
abstract: electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward ethyl acetylene (c4h6) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of ethyl acetylene the pristine nanotubes is about -1.60kcal/mol. but when nanotube has been doped with si and al atoms, the adsorption energy ...
pressurized irrigation is a recent development that consumes more energy for the pressure produced. in thisstudy, energy consumption, waste and efficiency were investigated at a diesel and electrical sprinklerirrigation pumping plant in some fields in hamadan province during 2007-8. nebraska performance criteria(npc) were used to compare sprinkler irrigation pumping plant performance. the resul...
one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...
the biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. efficient utilization of existing infrastructures has a prominent role in response to the challenges. energy hub approach embraces performance of different energy networks. energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in...
electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...
in this paper an optimal controller is proposed for a self-balancing electrical vehicle called segway pt. this vehicle has one platform and two wheels on the sides and the rider stands on the platform. a handlebar, as a navigator, is attached to the body of segway, with which the rider controls the vehicle. since segway uses electrical energy produced by batteries, resource consumption manageme...
