A wireless sensor network (WSN) having less cost, less power, small in size and multifunctional sensor node. Routing protocols in WSNs highlight on limited battery power, limited transmission range as well as processing and storage capabilities. The most important thing of a routing protocol, in order to be efficient for WSNs, is the energy consumption and the extension of the network's life ti...

Aims: The aim of this study was to survey the agronomic practices that practiced by farmers for potato and cucumber crops, estimate water productivity these crops.
 Study Design: A questionnaire designed collect data about during growing period cultivated in open field Place Duration Study: carried out at Al-Bqaia’h Kashda areas located Tubas governorate West Bank, Palestine between Decemb...

A large fraction of primary production is recycled through a marine protozoa–bacterioplankton predator– prey chain in most aquatic ecosystems. The size of food resources and the ratio between predators and prey determine the organic matter transfer through the ‘classical’ or the ‘microbial’ pathway (Azam et al. 1983). The effect of grazers on the prey can play an important role in selectivity a...

Despite the dramatic variety of application problems of signal and image analysis , it is possible to set oo some single subclasses of problems which allow for treating them in the uniied terms of respective standard mathematical optimization problems for which there exist eeective methods of solving. It was even Leonard Euler who marked that everything what happens in the world bears the sense...

Despite a prevailing assumption in the developmental literature that changes in continuous quantities (i.e., surface area, duration) are easier to detect than changes in number, very little research has focused on the verity of this assumption. The few studies that have directly examined infants' discriminations of continuous extent have revealed that infants discriminate the duration of a sing...

This study evaluated the influence of variety type on dilute acid pretreatment and enzymatic hydrolysis responses in terms of xylose, glucose and total combined sugar yields of eight varieties of sugarcane bagasse. The pretreatment was carried out in small tubular reactors. The materials were pretreated under five different conditions and hydrolysed with a standard enzyme dosage (15 FPU/g water...

April 2006 | Volume 3 | Issue 4 | e182 Over the last twenty years, attention defi cit hyperactivity disorder (ADHD) has emerged as a disorder of importance in childhood. Prescription of psychostimulants for ADHD escalated in many countries through the 1990s. Between 1990 and 1995, prescriptions of methylphenidate for young people increased 2.5-fold in the US [1], and 5-fold in Canada [2]. In Ne...

We propose a universal no-reference (NR) image quality assessment (QA) index that does not require training on human opinion scores. The new index utilizes perceptually relevant image features extracted from the distorted image. These include the mean phase con-gruency (PC) of the image, the entropy of the phase congruencyPC image, the entropy of the distorted image, and the mean gradient magni...
