This study aims to investigate the virtual class management experiences of teachers. The research was designed by adopting a qualitative approach. maximum variation sampling method, one purposive methods, used while determining group research. In this context, interviews were conducted with 18 teachers working in different years seniority, branches, and school types. Semi-structured interview f...

— We preformed two studies to investigate the cognitive effects related to two important dimensions of virtual environment systems: travel technique and display. Options for both elements vary significantly in quality and cost. Our first study examined four different methods of travel in an virtual environment and their effect on cognition. Our second study examined the effects of large display...

[1] Aerosol optical properties and the spectral behavior of the aerosol optical depth (AOD) over Kanpur, an urban-industrial city in the Ganga basin, have been presented for the first time. Measurements by the ground-based Aerosol Robotic Network (AERONET) during January 2001 to December 2003 show pronounced seasonal influence, with maximum dust loading during the premonsoon season (April–May)....

Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed w...

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-...

Visualization of sound propagation inside rooms is one of the main purposes of room acoustic simulations. Visualization is often applied in teaching, but also consultants need visualization to understand better the propagation of sound waves in complex cases. Traditionally, propagation paths of sound rays or image sources (representing reflections) have been applied in visualization. In additio...

The digital waveguide mesh (DWM) and related finite difference time domain techniques offer significant promise for room acoustics simulation problems. However high resolution 3-D DWMs of large spaces remain beyond the capabilities of current desktop based computers, due to prohibitively long run-times and large memory requirements. This paper examines how hybrid room impulse response synthesis...

The Virtual Singing Studio (VSS) is a loudspeaker-based room acoustics simulation for real-time musical performance under development at the AudioLab, University of York. An objective evaluation of the VSS found that relative differences between T30 values of the input (real) and output (virtual) Room Impulse Responses fall within the double tolerance subjective limen (10%). In addition a consi...
