Self-reconfiguration of robotic manipulators under joint failure can be achieved via fault-tolerance strategies. Faulttolerant manipulators are required to continue their endeffector motion with a minimum velocity jump, when failures occur to their joints. Optimal fault tolerance of the manipulators requires a framework that can map the velocity jump of the end-effector to the compensating join...

Fluidized beds are used in a variety of process industries because they provide uniform temperature distributions, low pressure drops, and high heat/mass rates. Minimum fluidization velocity is an important factor in understanding the hydrodynamic behavior of fluidized beds, and this characteristic may be modified through high frequency (sound) vibrations. The effects caused by sound wave frequ...

General anesthetics have been shown to perturb the membrane properties of excitable tissues. Due to their lipid solubility, anesthetics dissolve in every membrane, penetrate into organelles and interact with numerous cellular structures in multiple ways. Several studies indicate that anesthetics alter membrane fluidity and decrease the phase-transition temperature. However, the required concent...

Experiments to determine positions of spherical and long particles and the orientation of long particles can be carried out in a stationary frame by fluidizing particle in a balance of the buoyant weight of the heavier than liquid particle with (1) drag, which will be realized in a vertical tube apparatus (2) hydrodynamic lift (perpendicular to flow, as in a lifting aircraft) which will be real...

Analysis of electron spin resonance spectra of 5-doxyl stearic acid in aqueous suspensions of Clostridium acetobutylicum ATCC 824 and the butanol-tolerant SA-2 derivative during a small-scale fermentation at three different butanol challenge levels indicated that the SA-2 strain is able to respond to the physical fluidizing effect of high (1.5%) butanol challenge by reducing its membrane fluidi...

The objective of this study was to establish the baseline retinal hemodynamic characteristics of stratified groups of diabetic patients at increasing risk for the development of diabetic macular edema (DME). Group 1 had 50 control subjects, group 2 had 56 diabetic patients without clinically visible retinopathy, group 3 had 54 diabetic patients with microaneurysms and/or hard exudates within tw...

Abstract In this work, heat transfer, wall-to-bed, characteristics from elliptic tubes exchangers, both inline and staggered arrangements, were studied experimentally. Bundles of twenty the same total surface area 0.015 m 2 a length 200 mm are immersed in bed granulated charcoal different grain sizes, 2, 4 6 mm. Air was used as fluidizing fluid. One these which made copper, instrumented, electr...

This paper presents an improved neural computation where scheme for kinematic control of redundant manipulators based on infinity-norm joint velocity minimization. Compared with a previous neural network approach to minimum infinity-non kinematic control, the present approach is less complex in terms of cost of architecture. The recurrent neural network explicitly minimizes the maximum componen...

An accurate prediction of the minimum fluidization velocity is a crucial hydrodynamic aspect of the design of fluidized bed reactors. Common approaches for the prediction of the minimum fluidization velocities of binary-solid fluidized beds are first discussed here. The data of our own careful experimental investigation involving a binary-solid pair fluidized with water is presented. The effect...
