This tutorial paper provides an overview of design considerations for semiconductor radiation detectors and electronics in high radiation environments. Problems specific to particle accelerator applications are emphasized and many of the presented results originated in extensive studies of radiation effects in large scale particle detectors for the SSC and LHC. Basic radiation damage mechanisms...
We analyze the dynamics of fast electrons in plasmas containing partially ionized impurity atoms, where the screening effect of bound electrons must be included. We derive analytical expressions for the deflection and slowing-down frequencies, and show that they are increased significantly compared to the results obtained with complete screening, already at subrelativistic electron energies. Fu...
Jitter behavior has become increasingly critical design considerations for 12Gbps and 28Gbps transceiver devices featuring stringent specification compliance. In this paper, we present a comprehensive study of noise to jitter transfer mechanism, in which two dominant yet distinct jitter causes, power supply noise and signal crosstalk are investigated by phase noise method. The analysis reveals ...
endurance and interference mitigation of deeply-scaled multilevel flash memory. We address the relationships between data patterns and the raw bit error rate. An on-chip pseudorandom generator composed of an address-based seed location decoder is developed and evaluated with respect to uniformity. Experiments performed with 2x-nm and 4x-nm NAND flash memory devices illustrate the effectiveness ...
This paper discusses both risks and mitigation strategies for risks and threats associated with physical device interfaces. To this end, a brief discussion of the I/O architecture found in the Microsoft Windows operating system is followed by a review of several classes of attacks possible using only external devices attached to standard device interfaces of host computers. Based on this analys...
Performance Evaluation of Threshold-Based TOA Estimation Techniques Using IR-UWB Indoor Measurements
Ultra-wide bandwidth (UWB) technology is a viable candidate for enabling accurate localization through time of arrival (TOA) based ranging techniques. These ranging techniques exploit the high time resolution of the UWB signals to estimate the TOA of the first signal path. Nevertheless, these techniques are facing the problem of proper multipath mitigation especially in harsh propagation enviro...
In emergency and crisis situations (ECS) like earthquakes, tsunamis, terrorist attacks, it is very important that communication facilities are operative to provide services both to rescue teams and civilians. In ECS it is very common that communication premises are often unable to provide services, either due to physical damages or traffic overload. In such a case there is the need for rapid re...
Large oceanic migrants play important roles in ecosystems, yet many species are of conservation concern as a result of anthropogenic threats, of which incidental capture by fisheries is frequently identified. The last large populations of the leatherback turtle, Dermochelys coriacea, occur in the Atlantic Ocean, but interactions with industrial fisheries could jeopardize recent positive populat...
1. Introduction A multitude of commercial devices transmit in the unlicensed 2.4 GHz ISM band, and these devices are likely to interfere with each other. These effects are compounded in highly populated metropolitan areas with large numbers of microwave ovens, Bluetooth devices, cord-less phones, wireless game controllers, and other devices which occupy the ISM band. This contributes to an ever...
Radon gas is the second leading cause of lung cancer, causing thousands of deaths annually. It can be a problem for people or animals in houses, workplaces, schools or any building. Therefore, its mitigation has become essential to avoid health problems and to prevent radon from interfering in radioactive measurements. This study describes the implementation of radon mitigation systems at a rad...
