Finite element analysis on two wheeler gear drive

Abstract: The determination of actual fillet and contact stresses during a mesh cycle of a gear drive is very difficult since these are depends on load shared by a pair during a mesh cycle As the mesh stiffness differs at different contact points along the path of contact, it significantly affects the load sharing ratio (LSR) between the simultaneously meshed contact pairs The present research work concentrates on the load sharing behavior and related fillet and contact stresses of two wheeler gear drive These are evaluated by using a finite element method The gear drives are simulated for five different torques, and results are discussed in this work and it is found that the load on a pair, fillet and contact stresses are maximum when the single pair is in contact during a mesh cycle

Rtpg based built in self test for test compression

Abstract: Built In Self Test (BIST) is used to test the working functions of IC circuit and it is one of the merit in IC’s to check all the working functions inside the IC circuit. And one of the other cons of BIST is it does not need any other additional device or circuit to test the functions of IC as it has additional power and additional circuit than other devices. Thus BIST reduces the power consumption of addition circuit by consuming considerable power. There is no solution to overcome the problem of consumption of larger power even there are vast methods to reduce consumption of power. But one of the best existing power reduction method in BIST is PRPG, as it gives pseudo Random patterns to test. But it also produce considerable power consumption due to toggling and repetition of patterns. Therefore we can use RTPG to overcome the drawbacks of toggling and repetition in PRPG. RTPG is the Random Test Pattern Generator uses Multiple in Input Signature Register (MIST) in order to reduce the repetition. So the power consumption can be reduced by reducing the pattern in our proposed system.

7-Diethyl­amino-3-[(2Z)-3-(6-meth­oxy-2-naphth­yl)prop-2-eno­yl]-2H-chromen-2-one

Abstract: The geometric parameters of the title mol­ecule, C27H25NO4, are in the usual ranges. The central C=C double bond is trans configured, with the two C atoms slightly twisted out of the plane of the naphthyl group. The dihedral angle between the two fused ring systems is 40.90 (4)°.

1-(2-bromo-5-methoxybenzoyl)thiosemicarbazide

Abstract: The geometric parameters of the title molecule, C9H10BrN3O2S, are in the usual ranges. The mean plane of the thiourea group is almost parallel to the plane of the benzene ring dihedral angle = 8.40 (12)degrees]. Only the torsion angles about the C-carbonyl - C-aromatic bond and the N-N bond differ significantly from 0 or 180 degrees. The crystal packing is stabilized by N-H center dot center dot center dot O and N-H center dot center dot center dot S hydrogen bonds.

2-Bromo-5-methoxybenzohydrazide

Abstract: In the title compound, C8H9BrN2O2, the amide bond is in a cis configuation. The N-N-C = O group is planar torsion angle 0.6 ( 6)degrees] and forms a dihedral angle of 46.4 ( 2)degrees with the aromatic ring. The crystal packing is stabilized by two strong and one rather weak N-H center dot center dot center dot O hydrogen bonds.
