Ramp schemes are means by which a (large) secret can be shared among a group of participants in such a way that only sets of at least k participants can reconstruct the secret and the amount of information that of less than k participants can obtain is strictly controlled. This is of the concept of a threshold scheme. The current theory concerning ramp schemes will be here alongside some new re...
در این تحقیق به منظور بررسی نهشته¬های منسوب به کرتاسه در حاشیه شرقی بلوک لوت، دو برش به نام¬های برش نیمبلوک و برش قومنجان اندازه¬گیری شده است. برش نیمبولوک در شمال غرب شهرستان قائن و برش قومنجان در جنوب غرب شهرستان قائن قرار دارد. این برش¬ها از نظر فسیل-شناسی، پالئواکولوژی و محیط رسوبی مورد بررسی قرار گرفتند. در این مطالعه تعداد 27 جنس و 31 گونه از انواع فرامینیفرهای بنتیک و پلانکتونیک شناسایی ...
Pipeline networks are one of the key infrastructures of our modern life. Proactive monitoring and frequent inspection of pipeline networks are very important for sustaining their safe and efficient functionalities. Existing monitoring and maintenance approaches are costly and inefficient because pipelines can be installed in large scale and in an inaccessible and hazardous environment. To overc...
Expressions characterizing the output voltage and propagation delay of a CMOS inverter driving a resistive-capacitive interconnect are presented in this paper. The MOS transistors are characterized by the th power law model. In order to emphasize the nonlinear behavior of a CMOS inverter, the interconnect is modeled as a lumped load. The propagation delay of a CMOS inverter is characterized for...
A new ramp metering strategy implemented on the Twin Cities freeway system to reduce ramp waiting times was evaluated through microsimulation of freeway activity. The study compared Stratified Ramp Metering strategy with the previous Zone Metering Strategy and with no control strategy. Comparison with Zone, which was designed to favor freeway flow, showed the new strategy succeeded in greatly r...
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...
