with the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. many site-specific methods have been proposed for modeling indoor radio channels. among these methods, the ray tracing algorithm and the finite-difference time domain (fdtd) method are the most popular ones. the ray tracing approach ...

Computer aided modeling and simulation of complex physical systems, using components from multiple domains, such as electrical, mechanical, and hydraulic, have in recent years witnessed a significant growth of interest. Generalpurpose simulation tools, e.g., Simulink, using block diagrams and causal connections have dominated the area for years. However, in the last decade novel languages, (e.g...

Background: Non-organizational or non-occupational factors are among the most important risk factors that significantly influence the emergence of occupational accidents. This study aimed to investigate the association between non-organizational factors and occupational accidents. Materials and Methods: In this descriptive study the structural equation modeling was applied on the data that was...

Objectives: Hypertension is a global major health challenge and mechanisms related to the risk factors associated with it are poorly understood. Therefore, we used structural modeling to test a hypothesized model to identify factors associated with hypertension.  Methods: A cross-sectional population based survey, was performed and the data related to a random representative sample of 9704 sub...

The current paper examined the relationship between perceived characteristics of the learning environment in an e-module in relation to test performance among a group of e-learners. Using structural equation modelling, the relationship between these variables is further explored in terms of the proposed double mediation as outlined by Ning and Downing. These authors initially proposed that moti...

Recent years have witnessed an increasing interest in the flipped classroom model, and many flipped programs have been funded and implemented to explore the effectiveness of this new model. However, previous studies centering on comparative assessment have indicated that it is not always entirely successful in terms of promoting students’ performance and/or satisfaction, which warrants further ...

Article history: Received 28 January 2009 Received in revised form 8 March 2010 Accepted 9 March 2010 Available online 14 October 2010 Despite its theoretical and managerial significance, subsidiary entrepreneurship and its effects on subsidiary contribution remain underexplored in the literature. We propose that subsidiary entrepreneurship encourages more creative strategic responses to escala...

A structural equation model analysis of data from a 2003 national random sample survey (n = 478) on informational technology (IT) reveals important direct and indirect effects of generational demographic and attitudinal differences on electronic forms of political participation. Younger respondents reported more support for IT and fewer technological disadvantages compared to older respondents....

Distance education has been the topic of a substantial amount of research. However, prior studies have shown mixed results when trying to determine if a difference exists in student satisfaction between students in distance courses versus traditional courses. Prior empirical studies have been too narrow in scope, and a more comprehensive model is needed to better explain the factors influencing...
