The generalized integral transform technique (GITT) is employed to obtain an exact solution for the bending problem of fully clamped orthotropic rectangular plates. The use of the GITT approach in the analysis of the transverse deflection equation leads to a coupled system of fourth order differential equations in the dimensionless longitudinal spatial variable. The resulting transformed ODE sy...

This paper presents a method for reliable, real-time obstacle avoidance for an omnidirectional mobile robot, called “OmniMate.” The OmniMate is a large, rectangular-footprint platform with a flat loading deck measuring 184×92 cm (72×36”). To protect this vehicle from collisions we equipped it with a ring of 32 ultrasonic sensors and we developed a modified version of our earlier Vector Field Hi...

The current work explores a trial forced convective heat move from rectangular blades on an upward surface at low Reynolds numbers. removal for proper number of punctured and non-punctured fins, fin dividing, length was estimated in air stream fluctuating inlet speed some way or another info power somewhere the range 20W 70W. characteristics are investigated rectangular, circular, V-shape perfo...

We present a novel indicator for the effectiveness of longitudinal, convecting-radiating fins to dissipate heat. Starting from an analysis properties entropy rate steady state, we show how it is possible assess efficiency such devices by looking at amount produced in heat transfer process. Our study concerns both purely convective and convection-radiant takes advantage explicit expressions dist...

This paper presents a design of an underwater vehicle mimicking undulating fins of fish. To mimic the actual flexible fin of real fish, a fin-like mechanism is modeled with a series of connecting linkages. By virtue of a specially designed strip, each link is able to turn and slide with respect to the adjacent link. The driving linkages are used to form a mechanical fin consisting of several fi...

The Dlx5 and Dlx6 genes encode homeodomain transcription factors essential for the proper development of limbs in mammalian species. However, the role of their teleost counterparts in fin development has received little attention. Here, we show that dlx5a is an early marker of apical ectodermal cells of the pectoral fin buds and of the median fin fold, but also of cleithrum precursor cells duri...

l We review here the results obtained during the past several years in a series of computational and experimental investigations aimed at understanding the origin of high-force production in the flapping wings of insects and the flapping and deforming fins of fish and the incorporation of that information into bioinspired vehicle designs. We summarize the results obtained on pectoral fin force ...

During a survey of the Mali Hka River drainage in Hponkanrazi Wildlife Sanctuary in December 2015, a new species was collected and is described herein as Oreoglanis hponkanensis. It is a member of the Oreoglanis siamensis species group and can be distinguished from its congeners in having a unique combination of the following characters: lower lip with median notch and posterior margin entire, ...

In this work, analysis of heat transfer in porous fin with temperature-dependent thermal conductivity and internal heat generation is carried out using Chebychev spectral collocation method. The numerical solutions are used to investigate the influence of various parameters on the thermal performance of the porous fin. The results show that increase in convective parameter, porosity parameter, ...
