PURPOSE Guidelines suggest that individualized ramp protocols with treadmill times targeted between 8 and 12 minutes are most suitable to estimate exercise capacity. However, previous methods to determine individualized ramp rates and comparisons between ramp and standardized protocols have been limited to clinically referred populations. METHODS Forty-three healthy volunteers [median (interq...

Thresholds for detection and discrimination of the polarity (phase) of repetitive gratings with a ramp luminance profile were compared to sine-wave thresholds in normal and amblyopic observers. In the high-frequency range (4 cy/deg), normal observers detected ramp-wave gratings when the contrast of the fundamental spatial frequency was close to its independent threshold and discriminated the po...

Rapid confirmation of herpes simplex virus (HSV) is essential in many clinical settings. Viral isolation in cell culture is the standard method for diagnosing HSV infection, with confirmation by specific immunological staining. The performance of the Rapid Absorbent Matrix Pad (RAMP) HSV culture confirmation test was evaluated with specimens obtained from 71 patients with suspected HSV infectio...

the badamu formation (upper toarcian-middle bajocian) mainly consists of limestone and shale and has is cropped out in east of iran. the badamu formation conformably overlays shemshak formation and is underlaid sharply by hojedk formation in kerman area and is underlaid gradually by baghamshah formation in tabas and southern khorasan areas. the aim of this work is petrographical study of rocks ...

Repetitive, brief target ramp movements every few seconds lead to anticipatory acceleration before each ramp onset and anticipatory deceleration before ramp offset. We assessed whether identifying novel changes in the pursuit target would alter this pattern of anticipatory pursuit. Without target identification (TI), anticipatory acceleration increased when intervals between ramps were regular,...

this paper proposes a novel technique for solving generation scheduling and ramp rate constrained unit commitment. a modified objective function associated with a new start-up cost term is introduced in this paper. the proposed method is used to solve generating scheduling problem satisfying srr, minimum up and down time as well as ramp rate constraints. two case studies are conducted to implem...

This feedback control design, i:nlike the existing isolated feedback ramp controllers, Glso ta1:es into account (he ramp queue length. Using a !ionlizmr Hm ;ontrol design methodology, we formulate ihe problem in the desired setting to be able to utilize the results of the methodolop.

This paper describes the architecture of RAMP-White, an FPGA-based coherent shared memory machine. RAMP-White aims to provide a configurable coherent shared memory research platform while also demonstrating how large systems can be assembled using RAMP building blocks. The platform is sufficiently flexible to handle different coherency protocols, memory hierarchies and even processor ISAs and i...
