Automatic plate recognition of vehicles is of great importance in route management systems. Especially that such systems require real-time algorithms to perform the plate recognition task as soon as possible. In this paper, a new plate recognition system based on a fuzzy noise removal technique and the opposition-based micro-differential evolution (OMDE) algorithms is presented. Since populatio...

In this article, axisymmetric buckling behavior of piezoelectric fiber reinforced polymeric composite (PFRPC) annular plate subjected to electro-thermo-mechanical field is presented utilizing principle of minimum potential energy. Boron-nitride nanotubes (BNNTs) are used as fibers. Full coupling between electrical, mechanical and thermal fields are considered according to a representative volum...

Background. In vitro studies have revealed a direct association between resin content and cytotoxicity of composite resins; however, implantation studies in this regard are sparse. This study investigates the relationship between filler content of composite resins and biocompatibility. Methods. This research employed twelve 180‒200-gr male Wistar rats, 1 nano-hybrid (Prime-Dent Inc.) and 1 micr...

A new microtransfer technique is described which uses a modified, V-bottom, disposable, 96-cup plastic plate that permits serial dilutions and direct rapid transfer to a recipient micro cell culture plate.

composite couple beams are the concrete elements consisting of longitudinal bars and steel plate, therefore suitable for shear transferring in couple shear walls with arranged gates in its height. in this paper, after modeling couple beams with and without steel plates with f.e methods and calibration the models with experimental results, effects of parameters such as thickness, height, length ...

Aim: This study was conducted to throw light on the effect of papain –based gel (Papacarié) on microleakage and microshear bond strength of two esthetic restorative materials ; glass ionomer restoration (Fuji IX GP) and light cured hybrid composite resin (Valux Plus, 3M ESPE). Methods: Microleakage test: thirty primary molars with carious occlusal surfaces were randomly assigned into three grou...

The design and analysis of piezoelectric actuators is rarely optimized for low mass applications. However, emerging technologies such as micro air vehicles, and microrobotics in general, demand high force, high displacement, low mass actuators. Utilization of generic piezoceramics and high performance composite materials coupled with intelligent use of geometry and novel driving techniques yiel...

We propose a simple technique for bacterial and yeast cfu estimations from diverse samples with no prior idea of viable counts, designated as single plate-serial dilution spotting (SP-SDS) with the prime recommendation of sample anchoring (100 stocks). For pure cultures, serial dilutions were prepared from 0.1 OD (100) stock and 20 μl aliquots of six dilutions (101-106) were applied as 10-15 mi...

Abstract: A structure of micro-electro-mechanical system (MEMS) linear phased array based on “multi-cell” element is designed to increase radiation sound pressure of transducer working in bending vibration mode at high frequency. In order to more accurately predict the resonant frequency of an element, the theoretical analysis of the dynamic equation of a fixed rectangular composite plate and f...

kocho and bula are fermented product of enset (ensete ventricosum). it is the staple food for 20 million people in ethiopia. the aim of study was to isolate, identify and characterize yeast species from fermented kocho and bulla by using biolog micro station. 300 kocho samples were collected from angacha district. 0.1ml of serially diluted samples were streaked on yeast pepton dextrose agar and...
