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...

Current models of the rib cage contain a discreet junction where the costal cartilage meets the rib bone. However, observations from a previous study find that the junction is not discreet and that this transition region varies in length among different subjects. Further investigation of this junction using a microCT scan found that the bone microstructure around the costal chondral junction ex...

tuberculous spondylitis is not an uncommon disease of the spine. near one percent of all cases of spinal tuberculosis (tb) involves craniocervical junction. hypoglossal nerve palsy is not an uncommon neurological finding, but isolated involvement of the hypoglossal nerve is rare and limited to case reports or small case series. here, we report a case of craniocervical junction tuberculosis pres...

background: recent researches have led to find strategies to prevent relapse and to improve survival for gastric cancer patients, including preoperative neo-adjuvant approaches. however, the efficacy of some neo-adjuvant regimens including 5-fluorouracil, cisplatin, and docetaxel have been less investigated. the present study evaluated the outcome and mid-term survival of patients with gastric ...

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...
