the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
Mobile devices in the IEEE 802.11 wireless local area network (WLAN) have the ability to transmit data frames at one of four transmission rates 1Mb/s, 2Mb/s, 5.5Mb/s and 11Mb/s. This is because the commercial WLAN transceivers are equipped with several modulation schemes. According to the characteristics of the modulation scheme, a higher transmission rate will result in a smaller transmission ...
To raise the transmission rate of wireless multicast system, an efficient transmission scheme based on adaptive demodulation (ADS) is proposed. Firstly, the working principle how ADS can exploit user’s transmission ability better is described. Then, the bit mapping method of ADS is formulated. Finally, to analyze the transmission ability of ADS, the expression of transmission rate is derived. N...
In the area of monetary and credit policy-making, the policy-makers should take into special consideration the interactions of monetary policy tool with ‘assets market’ and ‘money market’ while analyzing the relationship of the both with macroeconomic variables such as real production and inflation in a higher level. It is a must to get familiar with the mentioned matters in an attempt to effic...
Introduction: The first case of HIV-infection in Iran was a hemophilic child who was infected by imported blood products in 1989. Since then, the HIV epidemic in Iran has undergone significant changes. This study investigated the time variations of the epidemiology of reported HIV/AIDS -infections during 2011-2017 in Yazd, Iran. Methods: This analytical cross-sectional study was carried out us...
A real−time adaptive rate control algorithm for video transmission is presented. The proposed algorithm aims to determine the optimal rate at which the video should be sent through the network in order to minimize the expected distortion while meeting the delay requirements. The packet loss rate is assumed to be a function of the transmission rate. The nodes of the network over which video pack...
The purpose of the present research is to investigate the effective channels of the monetary transmission mechanism in Iran. To do so, we devised a New Keynesian Dynamic Stochastic General Equilibrium Model. In our model, the different types of nominal rigidities are introduced beside all the related structural equations, which are extracted and linearized around a steady state point. Furthermo...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
BACKGROUND The presence of an infected family member significantly increases the risk of HBV transmission, but many socio-demographic and viral characteristics of family members affect the transmission rate. OBJECTIVES In this study, we have used data mining techniques to investigate the impact of different variables in intrafamilial transmission of HBV infection. PATIENTS AND METHODS demog...
