In this paper a hybrid active DC line conditioner for fluctuations and ripples reduction in voltage and current of DC power systems is proposed. Malfunctions in operation of equipments and systems which are supplied by low quality distribution power systems are one of the main effects of DC voltage ripple. In the proposed configuration a hybrid system including series and shunt active line ...
In this study, an indoor fish farm was selected to assess the biological treatment of the waste effluents. The purification lagoon surface was completely grown by target species, Nasturtium aquaticum. Six stations were selected as the water source, the farm outlet, the starting point of outlet water to the lagoon and three next other sampling stations. The averages of many chemical parameters ...
understanding the relationship between sink and source in maize is of prime importance in maize growing regions. in this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the college of agriculture, shiraz university, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of sc704 maize hybrid. a fa...
Backgrounds and Objective: In arid and semi-arid regions of the world, urban runoff as a source of water restoration and is considered valuable. Wastewater treatment, while preserving the environment, it can be considered as water source. The aim of this study to evaluate the possibility of using powder grain Peregrina in wastewater treatment in comparing with Alum and PloyAluminum Chloride (PA...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Sink location is considered as a basic service in geographic routing in wireless sensor networks. Obtaining the location of sink node by source node using an efficient method with low complexity has always been a challenging issue in research. In this paper, a sink location algorithm based on Fano plane is proposed. The research challenge is how to ensure the intersection of two SLQ (Location Q...
In Delaware, mosquito control is performed through the multi-disciplinary techniques of Integrated Pest Management (IPM) that advocates and practices (in this preferential order): 1) source reduction (elimination of mosquito breeding sites); 2) surveillance (determining mosquito population sizes and in turn directing the need and specific areas for control by insecticides); 3) larviciding (cont...
Usage of Image has been increasing and used in many applications. Image compression plays vital role in saving storage space and saving time while sending images over network. A new compression technique proposed to achieve more compression ratio by reducing number of source symbols. The source symbols are reduced by applying source symbols reduction and further the Huffman coding is applied to...
Speckle in optical coherence tomography (OCT) images originates in the high spatial coherence of incident light that enables interference of light backscattered from spatially heterogenous tissue specimens. We report results of a numerical simulation and an experiment to test speckle reduction using a partially spatially coherent source. A Gaussian-Schell model for a partially spatially coheren...
