In this paper, the dynamic analysis of a translating five-bar linkage mechanism is presented. The model developed with applied force to crank arm resolved into two principal planes, that is, x- and y- directions resulting reaction forces moments at pin joints determined various acceleration 0, 10, 20, 30 40 m/s2 in direction as well opposite rotation. It was observed horizontal were decreasing ...
In the present work, optimal balancing of planar six-bar mechanism is investigated to minimize fluctuations shaking force and moment. An optimization problem formulated for by developing an objective function. The genetic algorithm MINITAB software were used solve problem. selection weighting factors has a crucial role obtain optimum values design parameters. Two sets considered as per contribu...
Members of the Bin/amphiphysin/Rvs (BAR) domain protein superfamily are involved in membrane remodeling in various cellular pathways ranging from endocytic vesicle and T-tubule formation to cell migration and neuromorphogenesis. Membrane curvature induction and stabilization are encoded within the BAR or Fer-CIP4 homology-BAR (F-BAR) domains, alpha-helical coiled coils that dimerize into membra...
We study the transmission by two consecutive four-bar linkages with aligned frame links. The paper focusses on so-called “reducible” examples on the sphere where the 4-4-correspondance between the input angle of the first four-bar and the output-angle of the second one splits. Also the question is discussed whether the components can equal the transmission of a single four-bar. A new family of ...
Current therapy exercisers having one degree-of-freedom for rehabilitating single muscle groups are limited; an efficient functional rehabilitation process requires multiple muscles group’s actions within complex movements of the limbs. In this paper an exerciser for active and passive movement of upper limb is proposed. Its structure is based on a five-bar mechanism actuated by two motors. Thi...
The interaction between cosmic rays and the gravitational wave bar detector NAUTILUS is experimentally studied with the aluminum bar at temperature of T=1.5 K. The results are compared with those obtained in the previous runs when the bar was at T=0.14 K. The results of the run at T = 1.5 K are in agreement with the thermo-acoustic model; no large signals at unexpected rate are noticed, unlike ...
Presynaptic, electron-dense, cytoplasmic protrusions such as the T-bar (Drosophila) or ribbon (vertebrates) are believed to facilitate vesicle movement to the active zone (AZ) of synapses throughout the nervous system. The molecular composition of these structures including the T-bar and ribbon are largely unknown, as are the mechanisms that specify their synapse-specific assembly and distribut...
