Most conventional techniques for the determination of microalgae lipid content are time consuming and in most cases are indirect and require excessive sample preparations. This work presents a new technique that utilizes radio frequency (RF) for rapid lipid quantification, without the need for sample preparation. Tests showed that a shift in the resonance frequency of a RF open-ended coaxial re...

We propose a modification of the IEEE 802.16e hard handover (HHO) procedure, which significantly reduces the handover latency constraint of the original HHO procedure in IEEE 802.16e networks. It allows a better handling of the delay-sensitive traffic by avoiding unnecessary time-consuming scanning and synchronization activity as well as simplifies the network re-entry procedure. With the help ...

â a model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. while the model’s solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the cpu time is decreased ess...

Manual fingerprint classification algorithms are very time consuming, and usually not accurate. Fast and accurate fingerprint classification is essential to each AFIS (Automatic Fingerprint Identification System). This paper investigates a fingerprint classification algorithm that reduces the complexity and costs associated with the fingerprint identification procedure. A new structural algorit...

This paper presents an efficient optimization procedure to find the optimal shapes of double curvature  arch  dams  considering  fluid–structure  interaction  subject  to  earthquake  loading. The optimization is carried out using a combination of the magnetic charged system search, big bang-big crunch algorithm and artificial neural network methods. Performing the finite element  analysis  dur...

Aims: Circumcision is a minor urologic surgery that is widely used in Iran and other Muslim and non-muslin countries. A common complication following this procedure is bleeding. The aim of this study was to compare compressive dressing with no dressing and conventional dressing options for circumcision in point of bleeding after circumcision. Materials & Methods: Between October 2010 and July ...

Over the past two decades, laparoscopy has advanced and multiple techniques for inguinal hernia repair have been established. Laparoscopic-assisted percutaneous extraperitoneal closure (LAPEC) for inguinal hernia repair in children, is one of the most simple and reliable methods. The present study aimed to assess the safety and feasibility of the LAPEC of inguinal hernia in children.From Januar...

animal models are used to model the observations of animal performance that are genetically dependent.these models are considered as generalized linear mixed models and the genetic correlation structure of data is considered through random effects of breeding values. one goal of the mentioned models is to estimate variance components. in this research, an approximate bayesian approach presented...

This paper presents an efficient data preprocessing procedure for the support of vector clustering (SVC) to reduce the size of a training dataset. Solving the optimization problem and labeling the data points with cluster labels are time-consuming in the SVC training procedure. This makes using SVC to process large datasets inefficient. We proposed a data preprocessing procedure to solve the pr...

Abstract Beyond the scope of conventional metasurface, which necessitates plenty computational resources and time, an inverse design approach using machine learning algorithms promises effective way for metasurface design. In this paper, benefiting from Deep Neural Network (DNN), procedure a in ultra-wide working frequency band is presented output unit cell structure can be directly computed by...
