The flow of packages of an express package carrier consists of pick ups at costumer locations by couriers and delivering the packages to a local station for sorting. The packages are then transported to a major regional sorting facility called the ramp. At the ramp, packages can be sorted again before departing to a hub. From the hub they are moved to the destination ramp, where the entire proc...

PURPOSE The work rate (WR) corresponding to ventilatory threshold (VT) is an appropriate intensity for regenerative and low-intensity training sessions. During incremental ramp exercise, VO(2) increase lags behind WR increase. Traditionally, a VO(2) time delay (t(d)) of 45 seconds is used to calculate the WR at VT from such tests. Considerable inaccuracies were observed when using this constant...

For the analog-to-digital conversion lab, we need a resetable ramp generator. Here, we explore building a ramp generator from a current source. We show two implementations that both use a PNP current source.

Along a non-uniform flow in a stream or river, the pressure, energy, and momentum coefficients tend to vary from section to section. These coefficients also tend to vary with the water depth and discharge. Although some researchers provided some values of these coefficients for special conditions, their spatial variability in accelerated flow has not been adequately investigated. To simplify ca...

To define the ratio of simian immunodeficiency virus (SIV) RNA molecules to infectious virions in plasma, a ramp-up-stage plasma pool was made from the earliest viral RNA (vRNA)-positive plasma samples (collected approximately 7 days after inoculation) from seven macaques, and a set-point-stage plasma pool was made from plasma samples collected 10 to 16 weeks after peak viremia from seven macaq...

We examine cosmic ray rejection methodology on data collected from InSb and Si:As detectors. The application of an Up-the-Ramp sampling technique with onthe-fly cosmic ray identification and mitigation is the focus of this study. This technique is valuable for space-based observatories which are exposed to high-radiation environments. We validate the Up-the-Ramp approach on radiation-test data ...

Production ramp-up appears to be the main challenge during the late phases of innovation processes: new product specifications have to walk along with new production processes and even new production facilities. Bringing new products to market at a required level of quality while meeting targeted time and cost, is the main goal of production ramp-up management. Literature stresses the importanc...

Electron densities at nuclei are difficult to calculate accurately with all-Gaussian basis sets because they lack an electron-nuclear cusp. The newly developed mixed ramp-Gaussian basis sets, such as R-31G, possess electron-nuclear cusps due to the presence of ramp functions in the basis. The R-31G basis set is a general-purpose mixed ramp-Gaussian basis set modeled on the 6-31G basis set. The ...

This paper proposes a distributed ramp signal generator of column-parallel single-slope ADCs for CMOS image sensors. This architecture does not require any power-hungry amplifiers of the conventional one but consists of miniaturized column-wise ramp signal generators connected together by metal wires, which achieves high linearity and high uniformity. Simulation results show less than 1LSB nonl...

This study attempts to develop a Geographic Information System (GIS) based system utilized in identifying ramp site that can potentially benefit from ramp signaling. To achieve this, this paper first identifies and evaluates existing ramp signaling guidelines, and then establishes a set of warrants with consideration for their appropriateness and the availability of the required data. A web GIS...
