Nanobeams are now widely used in numerous vibration frequency research. In this study, an eigenvalue problem has to determine the analysis of buckyball and spring attached end nanobeam. The frequencies system may be discovered using a single (2x2) matrix problem. A mathematical method for analyzing sensors nanobeams is presented paper. results, which obtained showed result that compatible with ...

In this dissertation, simple models of legged locomotion are developed mainly following the hypothesis that rather than reflecting two distinct phenomena, the fundamental gait patterns of walking and running can be described within a single conceptual framework that is based on compliant limb behavior. In Chapter 1, the most prominent mechanical paradigms of walking and running, namely the stif...

in this study, the longitudinal shrinkage behavior of knitted fabrics during drying has been studied. in this context, a model is presented to predict the longitudinal shrinkage of plain knitted fabric during drying process. in order to model the shrinkage behavior, a 1dof model consists of a mass, a linear spring and a linear damper have been used. in presented model the time-varying mass is c...

For most force measurement applications, the strain gage based transducer can be relied upon to faithfully convert a mechanical input into a proportional electrical analog output signal. However, when the mechanical input is either applied or changes at a rapid rate, the sensor may distort the conversion and the user should be aware of the possible consequences of this distortion. This article ...

In running, the spring-like axial behavior of stance limbs is a well-known and remarkably general feature. Here we consider how the rotational behavior of limbs affects running stability. It is commonly observed that running animals retract their limbs just prior to ground contact, moving each foot rearward towards the ground. In this study, we employ a conservative spring-mass model to test th...
