Optimal feedback control postulates that feedback responses depend on the task relevance of any perturbations. We test this prediction in a bimanual task, conceptually similar to balancing a laden tray, in which each hand could be perturbed up or down. Single-limb mechanical perturbations produced long-latency reflex responses ("rapid motor responses") in the contralateral limb of appropriate d...

in the present study, experimental investigations about the hydrodynamics of the conical cap tray (concap tray) have been carried out. the concap tray is an innovative and novel type of cap trays. the effect of the different weir height (2.5, 5 and 7 cm) on the weeping, entrainment and the total pressure drop for the concap tray was measured, compared and correlated. the hydraulic experiments w...

The Tower of Hanoi puzzle consists of n disks of distinct sizes distributed across 3 pegs. We will refer to a particular distribution of the disks across the pegs as a state and call it valid if on each peg disks form a pile with the disk sizes decreasing from bottom up. Since each disk can reside at one of 3 pegs, while the order of disks on each peg is uniquely defined by their sizes, the tot...

this research includes both experimental and cfd investigation in the hydrodynamic behavior of a new type of column tray introduced as “concap” tray. the proposed column tray is used in contactor columns especially in stripping columns. the hydrodynamics of this concap tray is investigated in a 1.2m in diameter column. using air-water system, the experiments were performed for different liquid ...

In this paper, novel equipment for laboratory studies of heterogeneously catalyzed reactive distillation is described. The so called D+R tray equipment consists of a combination of conventional bubble cap trays with sections that are filled with catalyst and through which the liquid flows when it passes from one distillation tray down to the next. It is designed so that the catalyst can be easi...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

With the wind turbines being produced toward to large scale and light weight, the flexibility of blade, drive mechanism and tower increase apparently. Loads suffered by wind turbines during operation become increasingly intricate. Some control approaches could be used to cut down these loads in orde to expand life cycle of generating sets. Aiming at the full load operation zone above rated wind...

Motivation Protein sequence alignment forms the basis for comparative modeling, the most reliable approach to protein structure prediction, among many other applications. Alignment between sequence families, or profile-profile alignment, represents one of the most, if not the most, sensitive means for homology detection but still necessitates improvement. We aim at improving the quality of prof...
