We apply Maxwell and Cattaneo’s relaxation approaches to the analysis of strong shockwaves in a two-dimensional viscous heat-conducting fluid. Good agreement results for reasonable values of Maxwell’s relaxation times. Instability results if the viscous relaxation time is too large. These relaxation terms have negligible effects on slower-paced subsonic problems, as is shown here for two-roll a...

Abstract Bistable metal sheets with a coiled transport geometry and an unfolded profile as second stable state, are of great interest lightweight components. It is well known that specific distribution residual stresses necessary to enable bistable properties. With the help numerical FE models, optimal process parameters for production such evaluated. Afterwards, incremental bending roll formin...

this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

The HMG-box domain of the human male sex-determining factor SRY, hSRY(HMG) (comprising residues 57-140 of the full-length sequence), binds DNA sequence-specifically in the minor groove, resulting in substantial DNA bending. The majority of point mutations resulting in 46X,Y sex reversal are located within this domain. One clinical de novo mutation, M64I in the full-length hSRY sequence, which c...

The modulus of elasticity (E) was determined in simple three- and four-point bending for an 0.0175" (3 X 0.008") stainless steel arch wire. Using variable light loads (10-160 g) to limit the elastic deflection of a wire to less than 5% of its beam length, the force-deflection profiles were determined for three nominal span lengths (L = 0.35", 0.75", and 1.00") in three-point bending and three n...

Rollover is one of the most dangerous events in driving Vehicles, specially the Sport Utility ones. This maneuver is the main reason for the majority of human and financial loss in transportation systems. The upcoming paper outlines the details as well as the plus points of a Fuzzy Logic Controller which is designed and simulated to reduce the rollover propensity of Vehicles, specially the ones...

[Purpose] The objective of this study was to perform forward bending of the trunk and reaching training in chronic stroke patients and to investigate subsequent changes in trunk control, dynamic balance, and gait. [Subject] Twenty-three chronic stroke patients were randomly divided into two groups, with 10 patients in the forward bending of the trunk and reaching group and 13 patients in the co...

Strain-induced failure is a major concern in wearable electronics. Herein, ~ 90-nm thick bismuth telluride film fabricated on 125-μm polyethylene terephthalate as the basis for flexible thermoelectric generator. To simulate induced mechanical strains during operation and roll-to-roll manufacture, both tensile buckling are studied. improve resilience, two types of substrate-to-coating interlayer...

DNA bending is an important structural feature for indirect readout in protein-DNA recognition. The binding of papillomavirus E2 transcription factors to their DNA binding sites is associated with DNA bending, providing an attractive model system to study the origins of sequence-specific DNA bending. The consensus E2 target is of the general form ACCGN(4)CGGT with a variable four base pair regi...

statement of problem: resin composites are a common type of tooth coloured restorative materials. these materials are brittle and their major shortcomings are sensitivity to flaws and defects, low tensile strength, and susceptibility to catastrophic failure.the role of home bleaching agents on the fracture toughness of resin composites using four-point bending test is scanty. objectives: to com...
