H.264 scalable video over finite-state Markov chain wireless channels
(2007-09-10)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 half Dl MPEG-4 encoder on the BSP-15 DSP
(2004-01-18)In this paper, we present the work on implementation of a half-Dl interlaced MPEG-4 encoder with Equator Technology DSP chip, BSP-15. The BSP-15 DSP consists mainly of a VLIW core, Co-processors, and media I/O interfaces. ... -
Hamiltonian formulation of induced gravity in two dimensions
(1989-10-15)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 ... -
Haptic-based Dental Procedure Training Simulator
(2005)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 ... -
Haptics-based Cataract Surgery Simulator
(2015-09-01)Surgical training using computer-based simulators are being adopted by many medical specialties, mainly because they offer several advantages to traditional training methods involving animals or cadavers. This article ... -
A Hard-Real-Time Juggling Simulator to Shape Human Sensitivity to Cues and Coordination of Muscles
(2018)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 ... -
Hardware-In-The-Loop Testbed for the Dynamics of Spacecraft Rendezvous and Capture
(2019-05)As more satellites are launched into orbit, the amount of space debris objects and defunct satellites in orbit that pose a risk to existing operational space systems is expected to grow. In addition, the risk of collision ... -
HAWQ DD
Execute an autonomous mission to deliver a package to a predetermined location. HAWQ DD (Hybrid Autonomous Winged Quadrotor Delivery Drone) transitions from quadcopter configuration to fixed wing and delivers the 3 kg ... -
HD 164492C: A rapidly rotating, Hα-bright, magnetic early B star associated with a 12.5 d spectroscopic binary
(2016-10-21)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 ... -
Health Behaviors Contributing to Overall Perceived Health, Mental and Physical Health Status, and Functional Impairment in Psychologists and Trainees
(2017-01)This study investigated the health behaviors and overall perceived health among psychologists and psychology trainees. Results revealed significant correlations between overall perceived health and physical activity, ... -
Health Risk Perceptions Regarding Electronic Nicotine Delivery Systems (ENDS) and Secondhand Exposure Behaviors Among U.S. Student Military Veterans
(2020-03)Student veterans are at high risk for electronic nicotine delivery systems (ENDS) use and for exposing others to secondhand vape. This study examined student veterans’ health risk perceptions of ENDS use and their ... -
Hearing the silence: Acknowledging the voice of my Latina sisters
(2015-05)Latina community college students experience a number of challenges during their transition to college. Findings from a larger study indicated that Latina community college students experienced racism and stereotyping on ... -
HEAT: runtime interception of Win32 functions
(2003-01-14)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 ... -
The heavily polluted atmosphere of the DAZ white dwarf GALEX J193156.8+011745
(2010-05-01)We report on the discovery of a new heavily polluted white dwarf. The DAZ white dwarf GALEX J193156.8+011745 was identified in a joint Galaxy Evolution Explorer (GALEX)/GSC survey of ultraviolet-excess objects. Optical ... -
Heavy-flavor electron-muon correlations in p+p and d+Au collisions at sNN =200 GeV
(2014-03-31)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 ... -
Heavy-ion elemental abundances in large solar energetic particle events and their implications for the seed population
(2006-09-20)We have surveyed the ∼0.1-10 MeV nucleonˉ¹ abundances of heavy ions from ³He through Fe in 64 large solar energetic particle (LSEP) events observed on board the Advanced Composition Explorer from 1997 November through 2005 ... -
Heavy-quark production in p + p and energy loss and flow of heavy quarks in Au + Au collisions at √sNN=200 GeV
(2011-10-10)Transverse momentum spectra of electrons (pTe) from semileptonic weak decays of heavy-flavor mesons in the range of 0.3<pTe<9.0 GeV/c have been measured at midrapidity (|y|<0.35) by the PHENIX experiment at the Relativistic ... -
