Comparison of Total Dose Responses on High Resolution
نویسنده
چکیده
High-speed and high-resolution analog-to-digital converters (ADC) are critical devices for space electronic systems. Analog Devices’s bipolar technology 12-bit A/D converter, AD574A, was proven to withstand up to 100 krad(Si) [1], but excessive power consumption limits its applications in many new high-speed and low-power system designs. Several other commercial 12-bit successive approximation register (SAR) A/ D converters with BiCMOS technology from different manufacturers have been tested and showed various results [2]. Failure modes were also quite different for those converters at different dose rates [3].

A total variation diminishing high resolution scheme for nonlinear conservation laws
In this paper we propose a novel high resolution scheme for scalar nonlinear hyperbolic conservation laws. The aim of high resolution schemes is to provide at least second order accuracy in smooth regions and produce sharp solutions near the discontinuities. We prove that the proposed scheme that is derived by utilizing an appropriate flux limiter is nonlinear stable in the sense of total varia...

Background: There are various methods to read out responses of a polymer-gel dosimeter, among which the Magnetic Resonance Imaging (MRI) technique is the most common one. Optimizing imaging protocols can have significant effect on the sensitivity and the dose resolution of polymer gel dosimeters. This study has investigated the effects of the number of echoes (NOE) and the echo time spacing (ES...

Major histocompatibility complex (MHC) represents an important genetic marker for manipulation to improve the health and productivity of cattle. It is closely associated with numerous disease susceptibilities and immune responses. Bovine MHC, also called bovine leukocyte antigen (BoLA), is considered as a suitable marker for genetic diversity studies. In cattle, most of the polymorphisms are lo...
