* Work supported in part by U. S. Department of Energy under contract No. DE-AC02-98CH10886 Abstract The concept for the new GSI accelerator facilities is based on a large synchrotron designed for operation at BR= 200 Tm and with the short cycle-time of about one second to achieve high average beam intensities. Superconducting magnets may reduce considerably investment and operating costs in co...

ABSTRACT We demonstrate that measurements obtained from NASA’s magnetospheric multiscale (MMS) mission support quasi-adiabatic electron heating in quasi-perpendicular shocks with temperature Te⊥ ∝ B1 + α, where B is the magnetic field strength and α represents departure adiabaticity. Adiabatic (α = 0) results conservation of moment on spatially increasing inside shock ramp. Negative < 0 ...

Pyrolysis of high impact polystyrene (HIPS) waste has been investigated under different process parameters, such as temperature, heating rate and types of zeolitic catalysts to produce valuable liquid products. Liquid, gas and coke as products of pyrolysis and aromatic, naphthene, olefin and paraffin as liquid components were obtained and their molecular weight distributions were studied with c...

-Based on ∆∑ modulator, an on-chip analog ramp generator for ADC BIST (Built-in Self Test) is presented. Technique uses the over-sample and ∆∑ noise shaping to generate the on-chip precise analog ramp with the precise control of a calibrator of ramp slope. Moreover, because of over-sample and ∆∑ noise shaping, the design of analog circuits is simplified, and is tolerant to the mismatch of techn...

Louisiana State University Center for Advanced Microstructures and Devices (CAMD) began a project to upgrade the storage ring and linac control systems in February 1997. At that time, control systems for the storage ring and linac were DEC VAX/VMS and VME/OS9 based systems, respectively. The objectives were to utilize inexpensive hardware, free software, and provide a flexible architecture wher...

OVERVIEW: The increasing sophistication of home electronics and telecommunication devices is propelling the demand for improved semiconductor devices. The SiGe (silicon germanium)-HBT (hetero-junction bipolar transistor) can realize high-speed operation, low noise, and low power consumption, therefore, its expected application to radio frequency IC communication devices is predicted to grow rap...

The general purpose of this study is to develop both efficient and equitable freeway ramp control strategies. Measures of efficiency and equity for ramp meters are defined and applied to data collected in the Twin Cities ramp metering shut-off experiment. A trade-off between efficiency and equity is evident from the results of data analysis. A new time-dependent optimization program for the glo...

Background Laying hens are often kept in barn or free-range systems where they must negotiate level changes in the house to access resources. However, collisions and resultant keel fractures are commonplace. Producers sometimes add ramps to make raised areas more accessible but designs vary and very little research has investigated bird preference or behaviour when using different ramp designs,...

A radiative collapse predictor has been developed using a machine-learning model with high-density plasma experiments in the Large Helical Device (LHD).
