In vehicular Ad-hoc networks (VANETs), vehicles can gain short connections to the Internet by using wireless access points (AP). A significant part of the connection time is the time required for acquiring an IP address via dynamic host configuration protocol (DHCP). Depending on a vehicle's speed and the AP coverage area, DHCP can consume up to 100 percent(More)
Recently, some researchers have performed extensive experiments to study the feasibility and performance of vehicle drive-thru access to roadside access points (APs). The experiments demonstrate that the duration of connectivity to the AP is limited. A drive-thru vehicle has an area of high signal strength near the AP, but experiences poor link quality when(More)
The submental-vertical (S-V) radiograph has become popular in the assessment of craniofacial asymmetry because of ease in identifying reliable midline reference structures. To date, no standards of asymmetry that use the S-V projection have been reported. Submental-vertical radiographs were obtained on 44 adults. Subjects were excluded if previous(More)
As a test of the 2-dimensional model of work stressors, the present study proposed differential relationships between challenge stressors and hindrance stressors and role-based performance, which were expected to be moderated by organizational support. In a sample of 215 employees across 61 offices of a state agency, the authors obtained a positive(More)
UNLABELLED Subjects with scores on the Functional Movement Screen (FMS) assessment of ≤14 or with at least 1 bilateral asymmetry have been shown to have greater future injury incidence than subjects with FMS scores >14 or no movement asymmetries. PURPOSE To determine if FMS injury risk factors extend to longitudinal competitive performance outcomes in(More)
The purpose of this study was to measure the relationship between quantitative changes in an epicardial electrocardiographic complex and times of total occlusion and reactive hyperemia in the coronary vessel that supplied the myocardium beneath the electrode. Fifty-six experiments were performed on 9 open-chest dog preparations in which the left anterior(More)
Patient monitoring is more than just the acquisition and accumulation of physiological data. In order for it to be efficacious in patient diagnosis and treatment, the professional staff must be continuously involved in protocol development, evaluation, and modification. Given the constraints of these tasks, of cost limitations, and of staff interest and(More)
