Packet and flow scheduling algorithms for WiMAX has been a topic of interest for a long time since the very inception of WiMAX networks. WiMAX offers advantages particularly in terms of Quality of service it offers over a longer range at the MAC level. In our work, we propose two credit based scheduling schemes one in which completed flows distributes the left over credits equally to all higher...

This paper considers methods for estimating the slope coe¢ cients in large panel data models that are robust to the presence of various forms of error cross section dependence. It introduces a general framework where error cross section dependence may arise because of unobserved common e¤ects and/or error spillover e¤ects due to spatial or other forms of local dependencies. Initially, this pape...

â â â  moral values of shanfara in , lamyat- alarab ode â  â  somayeh kazemi * â  jafar delshad ** â  â  in this descriptive-analytic study, the researchers aimed to study the verses of lamyat- al arab and examine the moral values and mental pains which made the poet shanfara express such values. â  this survey has been affected by a hadith that indicates the tendency of the poet to the moral v...

This paper proposes a test for the null of sphericity in a …xed e¤ects panel data model. It uses the Random Matrix Theory based approach of Ledoit and Wolf (2002) to test for the null of sphericity of the error terms in a …xed e¤ects panel model with a large number of cross-sectional units and time series observations. Since the errors are unobservable, the residuals from the …xed e¤ects regres...
