The RAMP (Research Accelerator for Multiprocessors) project is developing infrastructure to support high-speed emulation of large scale, massively parallel multiprocessor systems using FPGA platforms. In this paper, we describe our proposal for a RAMP Design Framework (RDF), which has a number of challenging goals. The framework must support both cycle-accurate emulation of detailed parameteriz...

Many CMOS image sensors now use columnparallel readout structure with single slope ADCs. Ramp generator in the ADCs is a critical building block since the performance of the ADCs depends a lot on the accuracy of the ramp signal. In this paper, we present several ramp generator architectures and compare their performance in terms of resolution, area, noise and reliability.

Rapid detection of West Nile virus (WNV) in mosquito pools is essential for predicting epizootics and epidemics. We compare the efficiency and sensitivity of the Rapid Analyte Measurement Platform (RAMP) to reverse transcriptase polymerase chain reaction (RT-PCR) from 2005 to 2008 from field mosquito populations in Mercer County, NJ. Overall, 316 pools tested negative and 115 pools tested posit...

Receptor activity modifying protein-3 (RAMP-3) has been shown to complex with the calcitonin receptor-like receptor establishing a functional receptor for adrenomedullin (AM). AM exhibits potent anti-proliferative and anti-migratory effects on rat mesangial cells (RMC). In this study we investigated the effect of platelet-derived growth factor (PDGF) on RAMP-3 expression in RMC. We show here th...

During the last century, there has been considerable economic growth and development of cities around the world. The growth has led to an expansion of car-ownership and ultimately increased congestion of the road network. Traffic engineers and transport planners have attempted to mitigate the consequences of congestion of motorways and freeways using a number of techniques. One of which has bee...

To examine the relationship of ramp design to truck accident rates, this paper presents an analysis of truck accidents in Washington State, plus a comparison to limited data from Colorado and California. We group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. We then compare these groups on the basis of truck accidents per location...

Abstract. The Spitzer Infrared Spectrograph (IRS) data are taken via readwithout-reset measurements to obtain multiple samples forming a photometric “ramp” for each pixel in an echellogram. Each ramp is linearized via a quadratic model. After linearization, a quality-assurance test is performed to determine how linear each pixel’s ramp has become. This is accomplished by fitting a straight line...

4S-ferrugineone and 4S,5S-ferrugineol as pheromones of palm weevils were synthesized in 3 and 4 steps, respectively, starting from nonane-5-one employing SAMP-/RAMP -hydrazone methodology. 5-nonanone is transformed to its corresponding RAMP hydrazone by reaction with the enantiomerically pure hydrazine RAMP. Metalation with lithium diisopropylamide (LDA) in ether to form azaenolate, followed by...
