We study a Digital Subscriber Line Access Multiplexer (DSLAM) that multiplexes streaming Packetized Telephony (PT) and/or Video-on-Demand (VoD) traffic. To this end, the distribution of the amount of work in a discrete-time single-server queueing model with heterogeneous sources and general packet lengths is calculated. Obtaining actual data concerning the distribution of this quantity is notor...

the problem of pole assignment, also known as an eigenvalue assignment, in linear discrete-time periodic systems in discs was solved by a novel method which employs elementary similarity operations. the former methods tried to assign the points inside the unit circle while preserving the stability of the discrete time periodic system. nevertheless, now we can obtain the location of eigenvalues ...

this study concerns to analyze femininity identity by psychoanalysis approach of lacan. psychoanalysis is certainly one of the most areas of debate within feminist artists. the main question of this research is: “how does video art show the femininity identity?” so, initially we tried to categorize different influential concepts of lacan’s psychoanalysis which is necessary to get to know his at...

we have investigated structure and electronic properties of au and si liner chains using the firstprinciplesplane wave pseudopotential method. the transport properties and conductance of these twoliner chains are studied using landauer approaches based on density functional theory (dft). weobtain density of states and band gap using kohn-sham and wannier functions as well as quantumconductivity...

Media richness theory is a well known theory in media adoption and use. In recent years, it has gone through much empirical examination; however, some aspects of the theory still remain largely untested. In the current study, we investigated a core premise of the theory that there exists an inherent and fixed lean-rich continuum of communication media. Our results indicated that media richness ...

Among several theories to explain how different communications media affect task performance, media richness theory is one of the most frequently cited. Media richness theory proposes that task performance will be improved when task information requirements are matched to a medium’s ability to convey information. The main objective of this research is to examine the media richness theory in a l...

Presently, designers of interactive narratives and video games have only a slender understanding of the aesthetic experiences their audiences and users seek. Using schema theory, this study articulates the two varieties of aesthetic pleasures that users of interactive works enjoy: immersion and engagement. It uses schema theory to define the characteristics of immersion and engagement in both c...
