background: there are many studies to investigate the effects of each interacting component of tumor-immune system interactions. in all these studies, the distinct effect of each component was investigated. as the interaction of tumor-immune system has feedback and is complex, the alternation of each component may affect other components indirectly. objective: because of the complexities of tum...

Despite many of the current social presence measures relying heavily on subjective post-test questionnaires, some researchers have identified the value of using online, behavioural measures. Gaze, and specifically mutual gaze, is known to be related to social perceptions of an interlocutor, as well as facilitating task performance during an interaction [1, 2, 17]. Second Life allows for the inv...

Damage detection of mechanical structures such as bridges is an important research problem in civil engineering. Using spatially distributed sensor time series data collected from a recent experiment on a local bridge in Upper State New York, we study noninvasive damage detection using information-theoretical methods. Several findings are in order. First, the time series data, which represent a...

An interaction integral method for evaluating mixed-mode stress intensity factors (SIFs) for two dimensional crack problems using NURBS-based isogeometric analysis method is investigated. The interaction integral method is based on the path independent J-integral. By introducing a known auxiliary field solution, the mixed-mode SIFs are calculated simultaneously. Among features of B-spline basis...

There exists many devices that generate three-dimensional illumination patterns. Analysis of the capabilities of three major device families using measures of partial coherence reveals specific illumination patterns that cannot be generated by each device family. Ray-based devices cannot achieve patterns with high resolution, coherent holographic devices cannot achieve certain intensity pattern...

In this paper we explore the use of shared representations to support creative activities, focussing on collaborative music making. We examine the effect that user interface features of shared representations have on mutual engagement and show that providing shared awareness mechanisms increases mutual engagement. In particular, we show through an empirical study of 78 participants that providi...

Normalized mutual power of radiation, active and reactive, has been analyzed in this paper. The sound source is an annular plate, clamped to a planar, rigid and infinite baffle. The plate’s vibrations are axisymmetric and sinusoidal with respect to time. A Kirchhoff-Love’s model of a perfectly elastic plate has been used. First, the integral formulas for the mutual sound power have been present...
