In this paper, a wireless channel is viewed as a heterogeneous network in the time domain, and an adaptive video transmission scheme for H.264 scalable video over wireless channels modeled as a finite-state Markov chain ...

A Hamiltonian formulation of the theory of induced gravity in two dimensions is constructed. This formulation differs from previous efforts in that the formalism is covariant under all relevant transformation groups. In ...

Since the beginning of the last century, simulators have been widely used in military and aviation. Recently, the use of simulation in medicine and dentistry has brought the attention of the research community, looking ...

Many virtual reality tasks incorporate auditory and haptic (or touch) feedback, in addition to visual displays of spatial information. Non-visual feedback modalities such as the former increase realism; but they may have ...

We employ high-resolution spectroscopy and spectropolarimetry to derive the physical properties and magnetic characteristics of the multiple systemHD164492C, located in the young open cluster M20. The spectrum reveals ...

Electronic nicotine delivery systems (ENDS), also known as electronic cigarettes, are portable battery-powered devices used to smoke or “vape” a flavored solution which usually contains nicotine. Many national organizations ...

Research has demonstrated a connection between burnout and self-rated health and health risk behaviors, specifically substance use, mental health problems, low physical activity, and sleep difficulties. However, studies ...

When researching in any field, it is always important to build upon existing work. In most research disciplines, the core base is well defined and widely documented. However, the basis of innovative research in computer ...

Background: Heavy-flavor modification in relativistic p(d)+A collisions are sensitive to different kinds of strong-interaction physics ranging from modifications of the nuclear wave function to initial- and final-state ...
