this study was intended to evaluate the quality of 30 honey samples, in terms of physicochemical properties such as moisture content, electrical conductivity, ash content, reducing sugars and sucrose, free acidity, ph, diastase activity, and hydroxymethylfurfural (hmf) content. moreover, three methods recommended by the international honey commission for the determination of hmf, including 1) h...

in this paper, asymmetric buckling analysis of functionally graded (fg) circular plates with temperature dependent property that subjected to the uniform radial compression and thermal loading is investigated. this plate is on an elastic medium that simulated by winkler and pasternak foundation. mechanical properties of the plate are assumed to vary nonlinearly by temperature change. the equili...

We present a laboratory calibration setup for the individual multi-point calibration of oxygen sensors. It is based on the electrochemical generation of oxygen in an electrolytic carrier solution. Under thorough control of the conditions, i.e., temperature, carrier solution flow rate, and electrolytic current, the amount of oxygen is strictly given by Faradays laws and can be controlled to with...

We consider a thermoelastic contact problem for several bodies under the conditions of unilateral mechanical through nonlinear Winkler surface layers and imperfect thermal contact. obtain weak formulation this in form system formed by variational equation inequality also an alternative linear equations. To solve equations thermomechanical problem, we develop parallel iterative Robin-type domain...

A novel exact analytical solution is derived for the equation y(4)+xny=0 in region x≥0, which important analysis of piles soil with stiffness varying depth. To date, solutions long are available only cases where n=−4, 0, and 1. For other values exponent n, have formerly been obtained numerically, mainly by finite-difference method or approximate solutions. An inherent difficulty obtaining beams...

The security nowadays considered as significant topic specifically in design smart home. This paper is dedicated on an authentication problem door lock using string matching technique based password string.
 work contains two main parts, Android application (remote control) and control circuit Arduino UNO, plus the communication medium Bluetooth technology which used to send receive inform...
