A Virtual Reality (VR) environment was created to study psychotic symptoms in patients and non-patients. Participants' task was to find five virtual characters that each had a small number label on his or her chest. The density and ethnic appearance of the virtual characters in the bar was controlled. For a non-patient group (N=24), results showed a significant main effect for density on partic...

Introduction:The necessity of using modern educational methods in light of the rapid changes in the needs of communities is felt. The purpose of this study was to compare the effect of three methods of lecture, virtual education and flipped classroom on learning, information retention and satisfaction of students of Isfahan University of Medical Sciences. method:In this quasi-experimental two-...

Audio presentation is an important modality in virtual storytelling. In this paper we present our work on audio presentation in our intelligent multimodal storytelling system, CONFUCIUS, which automatically generates 3D animation speech, and non-speech audio from natural language sentences. We provide an overview of the system and describe speech and non-speech audio in virtual storytelling by ...

We introduce a notion of intrinsic linking and knotting for virtual spatial graphs. Our theory gives two filtrations of the set of all graphs, allowing us to measure, in a sense, how intrinsically linked or knotted a graph is; we show that these filtrations are descending and non-terminating. We also provide several examples of intrinsically virtually linked and knotted graphs. As a byproduct, ...

Kishino's knot is not detected by the fundamental group or the bracket polynomial; these invariants cannot differentiate between Kishino's knot and the unknot. However, we can show that Kishino's knot is not equivalent to unknot by applying either the 3-strand bracket polynomial or the surface bracket polynomial. In this paper, we construct two non-trivial virtual knot diagrams, K D and K m , t...

An increasing number of developers of virtual classrooms offer keyboard support and additional features for improving accessibility. Especially blind users encounter barriers when participating in visually dominated synchronous learning sessions. The existent accessibility features facilitate their participation, but cannot guarantee an equal use in comparison to non-disabled users. This paper ...

An age-dependent repair model is proposed. The notion of the “age” of the product and the degree of repair are used to define the virtual age of the product. The virtual failure rate function and the virtual hazard function related to the lifetime of the product are discussed. Under a non-homogeneous Poisson process scenario the expected warranty costs for repairable products associated with li...

Let G be a locally compact group, and let WAP(G) denote the space of weakly almost periodic functions on G. We show that, if G is a [SIN]-group, but not compact, then the dual Banach algebra WAP(G)∗ does not have a normal, virtual diagonal. Consequently, whenever G is an amenable, non-compact [SIN]-group, WAP(G)∗ is an example of a Connes-amenable, dual Banach algebra without a normal, virtual ...
