We present the application of a numerical method to correct electron moments calculated on-board spacecraft from the effects of potential broadening and energy range truncation. Assuming a shape for the natural distribution of the ambient plasma and employing the scalar approximation, the on-board moments can be represented as non-linear integral functions of the underlying distribution. We hav...

The Communication Based Train Control (CBTC) performs real-time train position report and movement authority transmission through wireless communications between a wayside control center and a vehicle on-board computer. And it has increasing effects of railway capacity by allowing the high-density train control through a high information transmission amount between the on-board and the wayside....

Work has been conducted to develop REBCO (Rare-Earth Barium Copper Oxide) magnets for Maglev. REBCO is one of several high temperature superconducting materials and has a high current density at high temperatures and in high magnetic field environments. The REBCO coated conductor will make it possible to raise the operating temperature of on-board magnets without increasing the coil weight. Sin...

The growing interest in the development of electric vehicle charging system based on expanding green car market is to meet the system demand for high efficiency and high density output characteristics. In addition, according to increase the in-production of electric vehicle, it is going to increase developing plan for on board charging system in around the world. In this paper, the charge contr...

With the progress of system integration technology, a variety of noise problems, so-called power/signal integrity and EMI issues, have become very serious in the field of chip (LSI), package and board (PCB) design. These problems cause frequently the unexpected behaviors on the today’s high-density and high-speed circuits. Thus, useful remedies are strongly demanded and the development of novel...

As the demand for low-cost electronic systems increases, increasing wiring density/reducing printed circuit board (PCB) layer count becomes inevitable. This reality limits the PCB routing layer options of high-speed input/output (I/O) signals, making it more difficult to meet the next-generation product’s performance targets. For example, using densely wired microstrip routing on a PCB helps re...

This study investigated the effect of board type (unmodified vs. MAPE modified) on the surface quality and thickness swelling-water absorption properties of recycled high density polyethylene (HDPE) based wood plastic composites. Additionally, two commercially available coatings (cellulosic coating and polyurethane lacquer coating) were also applied to composite surfaces and their adhesion stre...

This paper describes a methodology to simulate the distributed inductive and capacitive effects introduced by the interconnects on RF board circuits and High Speed packages. This methodology is based on an equivalent RLC model, derived directly from the discretization of the planar electromagnetic field equations. We discuss the relation of the voltage and the current in the equivalent network ...

Childhood obesity is a major threat to individual health and society overall. Policies that support healthier food and beverage choices have been endorsed by many decision makers. These policies may reach a large proportion of the population or in some circumstances aim to reduce nutrition disparities to ensure health equity. The Nutrition and Obesity Policy Research and Evaluation Network (NOP...

The gamma-ray attenuation porosity evaluator (GRAPE) component of the multisensor track (MST) unit on board the JOIDES Resolution measures the saturated bulk density of sediments by relating the attenuation of gamma rays in a core sample to that of a standard with known density (aluminum). After reaching thermal equilibrium, unsplit core sections are routinely run through the MST system. The sa...
