Exercise video games (exergames) can motivate players to be more physically active. However, most exergames are controlled by confined and predefined movements and do not promote long-term motivation. Well-funded commercial games often excel at long-term motivation, but are not operated with motion input. Exercise My Game (XMG) is a design framework for turning offthe-shelf action games into fu...

In this paper dynamic damping properties of a nominated flexible structural adhesive have been identified using an extended-direct modal based joint identification method. It has been revealed that damping characteristics of adhesive are correlated to both frequency and mode shape. Young’s and shear moduli increase with frequency but damping on the other hand, decrease. The results showed that ...

Experimental damage mechanics of flip chip solder joints under current stressing is studied using 20 test vehicle flip chip modules. Three different failure modes are observed. The dominant damage mechanism is caused by the combined effect of electromigration and thermomigration, where void nucleation and growth lead to the ultimate failure of the module. It is observed that thermomigration dri...

A growing interface subject to noise is described by the KardarParisi-Zhang equation or, equivalently, the noisy Burgers equation. In one dimension this equation is analyzed by means of a weak noise canonical phase space approach applied to the associated Fokker-Planck equation. The growth morphology is characterized by a gas of nonlinear soliton modes with superimposed linear diffusive modes. ...

An energy transfer analysis of turbulent plane Couette ow is performed. It is found that nonlinear interaction between the 0; 1] modes is principally responsible for maintaining the mean streamwise turbulent velocity proole. The 0; 1] modes extract energy from the laminar ow by linear non-modal growth mechanisms and transfer it directly to the mean ow mode. The connection of this work to linear...

Abstract Early growth of density fluctuations of nuclear matter in spinodal region is investigated employing the stochastic mean-field approach. In contrast to the earlier treatments in which only collective modes were included in the calculations, in the present work non-collective modes are also included, thus providing a complete treatment of the density correlation functions. Calculations a...

To improve the understanding on CNT growth modes, the various processes, including thermal CVD, MP-CVD and ECR-CVD, have been used to deposit CNTs on nanoporous SBA-15 and Si wafer substrates with C(2)H(2) and H(2) as reaction gases. The experiments to vary process parameter of DeltaT, defined as the vector quantities of temperature at catalyst top minus it at catalyst bottom, were carried out ...
