Although flood maps based on the deterministic approach play an important role in minimizing flood losses, there is considerable uncertainty in calculating the level of water inundation. Roughness is a key parameter in water surface elevation. Since roughness is not easily measurable and is estimated based on experimental and laboratory methods, it introduces a significant degree of uncertainty...
One of the most important decisions companies should make in the process of selecting strategies to enter foreign markets is the extent to which they intend to control themselves and the extent of such international activities they choose to leave to other parties. Having comprehensively reviewed the related literature, the following 12 variables explaining the degree of tendency among compan...
In this paper, Generalized Aggregated Uncertainty measure 2 (GAU2), as a newuncertainty measure, is considered to evaluate uncertainty in a localization problem in which cameras’images are used. The theory that is applied to a hierarchical structure for a decision making to combinecameras’ images is Dezert-Smarandache theory. To evaluate decisions, an analysis of uncertainty isexecuted at every...
many constants and coefficient effect on the modeling results. in many cases, it is possible these constants and coefficients differ from their real values in the environment, but the modeling results adapted with real boundary conditions due to other factors adjustment during modeling. uncertainty analysis is a tool for assessing the effect of uncertainty of various factors on the modeling res...
Background and Objective: Cognitive and physiological components such as intolerance of uncertainty, cognitive avoidance and brain/behavior systems have a significant impact on generalized anxiety disorder. The mentioned components are considered as the main causes of the emergence and persistence of this disorder. The aim of this study was to compare brain/behavioral system activity, intoleran...
This article advocates factorized and hybrid dimensional decompositions (FDD/HDD), as alternatives to analysis-of-variance dimensional decomposition (ADD), for second-moment statistical analysis of multivariate functions. New formulas revealing the relationships between component functions of FDD and ADD are proposed. While ADD or FDD is relevant when a function is strongly additive or strongly...
In the recent past, adjoint methods have been successfully applied in error estimation of integral outputs (functionals) of the numerical solution of partial differential equations. The adjoint solution can also be used as a grid adaptation indicator, with the objective of optimally targeting and reducing the numerical error in the functional of interest below a prespecified threshold. In situa...
Objectives: The aim of the present study was to compare intolerance of uncertainty and worry among patients with generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD) and normal individuals. Method: Thirty one patients with GAD, thirty one patients with OCD and thirty one normal individuals were selected via inconvenient sampling. Data gathering was done using Intolerance of U...
Introduction: The main objective of this research work is to examine the effectiveness of cognitive-behavioral education (CBE) based on intolerance of uncertainty and emotional regulation on behavioral activation/inhibition systems (BIS) and generalized anxiety disorder (GAD) of students with social anxiety disorder. Methods: The target population was 300 students at Islamic Azad University of...
