Laminar free convection heat transfer from vertical and inclined arrays of horizontal isothermal cylinders in air was investigated experimentally and numerically. Experiments were carried out using Mach-Zehnder interferometer and the FLUENT code was used for numerical study. Investigation was performed for vertical and horizontal cylinder spacing from 2 to 5 and 0 to 2 cylinder diameters respec...

One of the major disadvantages of using Branch and Bound algorithm to solve permutation bases problems by computer is the size of main memory required. The single Array Branch and Bound (SABB) method introduction here aims to overcome this deficiency, using only N memory locations as a vector of size N, and a single cell C with N bits.

we present a method for  the construction of compactlysupported $left (begin{array}{lll}1 & 0 & -11 & 1 & 0 1 &  0 & 1end{array}right )$-wavelets  under a mild condition. wavelets inherit thesymmetry of the corresponding scaling function and satisfies thevanishing moment condition originating in the symbols of the scalingfunction. as an application, an  example is  provi...

In this paper, after a brief overview on laser warning system (LWS), a new structure for an optical array that is used in its optical subsystem is introduced. According to the laser threats’ wavelengths (0.5 – 1.6 µm) and our desirable field of view (FOV), we used 6 lenses for gathering the incident radiation and then optimized the optical array. Lenses’ radius, their se...

case presentation a preterm neonate with suspicious rt renal mass and oligohydramnios at prenatal ultrasound was hospitalized due to respiratory distress and hypertension. although postnatal ultrasound showed enlarged echogenic rt kidney and normal sized echogenic lt kidney, regarding to linear array transducer findings, arpkd was considered rather than renal mass. the diagnosis was confirmed a...
