DC thermal effects modelling for nanometric silicon-on-insulator (SOI) and bulk fin-shaped field-effect transistors (FinFETs) is presented. Among other features, the model incorporates self-heating effects (SHEs), velocity saturation and short-channel effects. SHEs are analysed in depth by means of thermal resistances, which are determined through an equivalent thermal circuit, accounting for t...

Locomotor strategies in terrestrial tetrapods have evolved from the utilisation of sinusoidal contractions of axial musculature, evident in ancestral fish species, to the reliance on powerful and complex limb muscles to provide propulsive force. Within tetrapods, a hindlimb-dominant locomotor strategy predominates, and its evolution is considered critical for the evident success of the tetrapod...

A triangular fin with variable fin base thickness is analyzed and optimized using a two-dimensional analytical method. The influence of fin base height and fin base thickness on the temperature in the fin is listed. For the fixed fin volumes, the maximum heat loss, the corresponding optimum fin effectiveness, fin base height and fin tip length as a function of the fin base thickness, convection...

Background: The treatment of femoral shaft fractures has always been a focus of interest especially in children, but may still remain a clinical problem and a subject of controversy. Objective: To compare the post-operative outcomes of hip spica and flexible intramedullary nails in treatment of femoral shaft fractures in children. Material & Methods: Randomized controlled trial conducted for si...

Fish propelled by body and/or caudal fin (BCF) locomotion can achieve high-efficiency and high-speed swimming performance, changing their motion to interact with external fluids. This flexural be prescribed through its curvature profile. work indicates that when the fish swims high efficiency, amplitude reaches a maximum at peduncle. In case of swimming, shows three maxima on entire length. It ...

This paper is a review of research work of last few years on heat transfer growth in offset-strip fin heat exchangers. It features a broad discussion on the application of enhanced heat transfer surfaces to offset strip fin heat exchangers. In this paper we are discussing 2D & 3D Analysis in OSF, Experimental & investigating research on OSFs, Analytical model to predict the heat transfer coeffi...

In this manuscript, a new method is proposed to provide a perfect tracking of the supercavitation system based on a new two-state model. The tracking of the pitch rate and angle of attack for fin and cavitator input is of the aim. The pitch rate of the supercavitation with respect to fin angle is found as a non-minimum phase behavior. This effect reduces the speed of command pitch rate. Control...

Designing a robotic fish is a challenging endeavor due to the non-linear dynamics of underwater environments. In this paper, we present an evolutionary computation approach for designing the caudal fin of a carangiform robotic fish. Evolutionary experiments are performed in a simulated environment utilizing a mathematical model to approximate the hydrodynamic motion of a flexible caudal fin. Wi...
