background: adjustment disorder (ajd) is a transient mental health condition emerging after stressful life events. its diagnostic criteria have recently been under revision which led to the development of the adjustment disorder–new module 20 (adnm-20) as a self-report assessment. objective: to identify a threshold value for people at high risk for ajd. methods: as part of a randomized controll...

On recent architectures, a numerical program may give different answers depending on the execution hardware and the compilation. Our goal is to formally prove properties about numerical programs that are true for multiple architectures and compilers. We propose an approach that states the rounding error of each floating-point computation whatever the environment. This approach is implemented in...

The goal of the study was to analyze patterns of participation and quality of discussion in Virtual Web School (VWS) mediated interaction in one elementary class. To this end, we examined the density of the interaction within class, participants' participation rates, participants’ position in the VWS mediated interaction, and the quality of their discourse. The data consisted of VWS log files a...

In this paper, an iterative method is constructed to find the least-squares solutions of generalized Sylvester equation A X B A X B A X B A X B C 1 1 1 2 2 2 3 3 3 4 4 4 + + + = , where [ ] X X X X 1 2 3 4 , , , is real matrices group, and i X satisfies different linear constraint. By this iterative method, for any initial matrix group ( ) ( ) ( ) ( )     X X X X 0 0 0 0 1 2 3 4 , , , withi...

The purpose of this study was to investigate traffic flow characteristics at off-ramp junctions in Iranian expressways. The study was conducted on the traffic behavior in isolated off-ramp vicinity of 6-lane expressways. The database consisted of traffic flow and traffic speed information extracted from videotapes. The relationship between diverging traffic flow in the right lane of expressway ...

conclusions in conclusion, mma official and simulated matches induce similar high intensity glycolytic demands and minimal changes to biochemical markers of muscle damage immediately following the fights. glycolytic availability prior to the fights was raised exclusively in response to official matches. objectives the main objective of this study was to compare biochemical responses to sparring...

the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...

network effects, increase in the value of consuming a product if many other consumers use the same product, is a feature of many markets of high-technology products. frequently cited examples of products exhibiting network effects are telecommunication or software products. this research explores the role of network effects in the consumer´s choice of mobile operator in tehran. for our empirica...

modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. in this paper, a lossy transmission line model of traveling wave switch (twsw) i...
