background: lifestyle-modification programs including physical activity are essential for both treatment and prevention of type 2 diabetes mellitus ( t2dm ). however, factors associated with physical activity among patients are poorly understood. this study applied social-cognitive theory (sct) for predicting determinants of physical activity among women with t2dm in iran, 2013. methods: in thi...

In the framework of our ongoing project [2, 3, 4], we aim at developing a Reactive Virtual Trainer (RVT), an intelligent virtual agents (IVA) who can not only perform exercises, but adjust those, and interweave the physical performance with explanations, correcting remarks and social chat. For an IVA in such a role where the demonstrated motion is to be copied by the user, the subtle, physicall...

For control law design it is necessary to work with controller models and plant models of diierent complexity. During the control law design iteration it should be possible to adjust both the complexity of the controller model and the complexity of the plant model in order to evaluate the compromise between necessary control complexity and achievable control performance. Controller models on th...

The creation of abstract models of physical systems is an important AI research area. I describe a program which can automatically construct such models for machines like mechanical clocks or watches. The program finds an appropriate set of state variables and determines how they change as time passes. The abstract model of the mechanical device may be used to numerically simulate its behavior....

Recent research in physical modeling of musical instruments for purposes of sound synthesis is reviewed. Recent references, results, and outstanding problems are highlighted for models of strings, winds, brasses, percussion, and acoustic spaces. Emphasis is placed on digital waveguide models and the musical acoustics research on which they are based.

today, organizations continuously try to find the ways to gain loyal customers because of their advantages. customer to customer interactions has attracted more attention among marketers in which customer-to-customer interactions has been known as one of the most important methods of creating loyal customers. the present paper seeks to propose a service model developed in traveling and tourism ...

dam spillways are the structures that lead rightly and safely the outflow downstream, so that the dam integrity can be guaranteed. many accidents with dams have been caused by an inadequate spillway design or insufficient capacity. to accurately respond the hydraulic spillways, designers use physical modeling for designing this kind of structures. the scale effect in the spillway modeling, as a...

This study presents a new approach for physical and material modeling of space frame-raft-soil system. The physical modeling consists of a modified Thimoshenko beam bending element with six degrees of freedom per node to model the beams and columns of the superstructure, a modified Mindlin's plate bending element with five degrees of freedom per node to represent the structural slabs and raft, ...
