The present study investigated depth perception in virtual environments. Twenty-three participants verbally estimated ten distances between 40 cm and 500 cm in three different virtual environments in two conditions: (1) only one target was presented or (2) ten targets were presented at the same time. Additionally, the presence of a metric aid was varied. A questionnaire assessed subjective rati...

We describe a series of experiments designed to test (1) whether human observers combine depth cues using a weighted average when depth estimates in different maps are nearly consistent, (2) whether human observers behave as robust estimators when depths become increasingly inconsistent, and (3) whether the weights used in the linear rule of combination change to reflect the estimated reliabili...

In order to mobilize shallow soil to participate in the interaction of piled raft foundation sufficiently, the concept of piled raft has been modified to new type of foundation named composite piled raft. In the system of composite piled raft, the short piles made of flexible materials is used to strengthen the shallow soft soil, while the long piles made of relatively rigid materials is used t...

Background: Syntax has a high importance among linguistic parameters and the prevalence of syntax deficits is relatively high in children with language disorders. As such, independent examination of syntax in language development is of paramount importance. In this regard, Iranian language pathologists are faced with the lack of standardized tests. The present study aimed to determine the most ...

In this study, urban pluvial flood risk is studied in an actual study area using scenario simulation method based on hydrodynamics. Real weather data and GIS (Geographic Information System) data are adopted to make the results reliable. A region in Haidian District of Beijing is selected as the study area. All the rainfall scenarios (about 200 scenarios) during an 8-year period (from January 1,...

Objective: The ways people use for social rank (dominance vs prestige) could explain difference attitude toward five moral foundations. The aim of this study was to investigate the differential relationship between prestige, dominance and moral foundations. Methods: This study conducted with 150 participants who respond to the moral foundation questionnaire and dominance-prestige scale. Multip...

We address three questions of Donald Monk. Two of them, [M2, Problems 50, 54], are related to attainment problems in equivalent definitions of hereditary density hd and hereditary Lindelöf degree hL. The third problem is [M2, Problem 14] and it is about subalgebra– Depth–relation. ∗ The second author thanks KBN (Polish Committee of Scientific Research) for partial support through grant 2 P03 A ...

course of the study. Environmental managers, production engineers, financial analysts, and other staff from the case study firms were instrumental in providing data, documents, and interviews that comprise the foundation for this study. Our analysis would not have been possible without their willingness to devote substantial time and staff resources to the project. A special thanks to those fir...
