The articulated intervention autonomous underwater vehicle (AIAUV) is an swimming manipulator with capabilities. Station-keeping and trajectory tracking are essential for the AIAUV to be able move in confined spaces perform tasks. In this article, we propose using a generalized super-twisting algorithm (GSTA), which extension of regular algorithm, position orientation base six degrees freedom (...

The liquid cargo contained in a partly-filled road tank vehicle is prone to dynamic slosh movement when subjected to external disturbances. The slosh behavior has been identified as a significant factor impairing the safety of liquid cargo transportation. The laboratory experiments have been conducted for analyzing fluid slosh in partly filled tanks. The experiment results measured under forced...

The purpose of this paper is to analyze and discuss the performance and stability of a tailless micro aerial vehicle with flexible articulated wings. The dihedral angles can be varied symmetrically on bothwings to control the aircraft speed independently of the angle of attack and flight-path angle, while an asymmetric dihedral setting can be used to control yaw in the absence of a vertical tai...

abstract a 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. the cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. the most important physical finding which ...

In this study, effect of adding in SiO2 nanoparticle in base fluid (water) in car radiator is investigated experimentally. Radiators are compact heat exchangers that optimized and evaluated by considering different working conditions. Car\'s cooling system, plays an important role in vehicle\'s performance, consists of two main parts, known as radiator and fan. Radiators are compact heat exchan...

The sophisticated and intricate connection between bat morphology and flight capabilities makes it challenging to employ conventional flying robots to replicate the aerial locomotion of these creatures. In recent work, a bat inspired soft Micro Aerial Vehicle (MAV) called Bat Bot (B2) with five Degrees of Actuation (DoA) has been constructed to mimic the flight behavior of a biological bat. Maj...

In this study the effect of liquisolid technique on the dissolution profile of spironolactone was evaluated. Different formulations of spironolactone liquisolid compacts were prepared using various amounts of non-volatile vehicles (Poly ethylene glycol 400 and glycerin). The ratio of microcrystalline cellulose (as carrier) to silica (as coating powder material) was 20 for all formulations. Afte...
