The objective of the study is to improve the understanding of relationships between multiple spatial scales and the development of micro-habitat as well as its co-dependence with the net-spinning caddisfly (Stenopsyche mamorada). In this study, two target riffles located in the Asa River basin were investigated during the spring of 2006. Three major findings of this research were that; 1. the t...
Introduction: In the recent two decades, a special kind of homelessness and rooflessness which is named rough sleepers has been appeared in our country, especially in the big city Tehran. The sleeping rough is a sign and resultant of other social issues in society and it also can lead to many more. Different governmental and non-governmental organizations have executed many interventional proje...
In this paper, three types of (philosophical, optimistic and pessimistic) multigranulation single valued neutrosophic (SVN) covering-based rough set models are presented, and these three models are applied to the problem of multi-criteria group decision making (MCGDM).Firstly, a type of SVN covering-based rough set model is proposed.Based on this rough set model, three types of mult...
fuzzy rough n-ary subhypergroups are introduced and characterized.
To tackle the problem with inexact, uncertainty and vague knowl- edge, constructive method is utilized to formulate lower and upper approx- imation sets. Rough set model over dual-universes in fuzzy approximation space is constructed. In this paper, we introduce the concept of rough set over dual-universes in fuzzy approximation space by means of cut set. Then, we discuss properties of rough se...
Large-eddy simulations of free surface flow over bed-mounted square bars are performed for laminar, transitional and turbulent flows at constant Froude number. Two different bar spacings selected corresponding to k-type (reattaching flow) roughness, respectively. The validated with experimental data convincing agreement between simulation measurement is obtained in terms water elevations stream...
Recent research suggests that the resurgence of bed bugs in the U.S. has occurred at an alarming rate. Assumptions have been made that socioeconomic status is not associated with the prevalence of bed bug infestations. Little information is available at the local level, however, about the prevalence of bed bugs in private homes. The authors' pilot study aimed to identify prevalence, knowledge, ...
