Abstract:

The antenna constitutes the air interface between wireless equipment and communication channel, thus, efficient operation is of great importance especially in compact user devices. An understanding of its behaviour within any communication system, and an accurate representation of its effects on received signals are vital. The nature of the multipath propagation channel and the local environment, the user's interference with its orientation and immediate vicinity are all factors that impact on antenna performance and need to be addressed. This thesis addresses issues directly arising from the

Abstract:

Treatment planning in radiation therapy is based on the calculation of dose distributions, aimed at best representing the physical dose distributions. The most promising avenue towards this goal is the Monte Carlo technique, whereby particle trajectories are simulated from a modelled radiation source into a patient volume. Following the trend of incorporating fast Monte Carlo algorithms in clinical electron beam dosimetry, Elekta CMS inc. commercialized an electron Monte Carlo (eMC) module implemented in the treatment planning system XiO. The algorithm is based on the XVMC code and allows for

Abstract:

The Earth Radiation Budget Experiment (ERBE) is an operational system of radiometric instruments placed in Earth orbit by the National Aeronautics and Space Administration (NASA). Its purpose is to monitor those components of the Earth radiation budget which influence the weather and climate. The active cavity radiometer (ACR) instruments on board the ERBE satellites are periodically calibrated against internal standards and against the relatively well-known solar constant. In order to better understand the dynamic behavior of the instruments, a high resolution dynamic model has been developed

Two aspects of the study of the Earth radiation budget and the effects of clouds on our climate system are considered in this dissertation : instrumentation and data interpretation. Numerical models have been developed to characterize the optical/thermal-radiative behavior, the dynamic electrothermal response and the structural thermal transients of radiometric channels. These models, applied to a satellite-borne scanning radiometer, are used to determine the instrument point spread function and the potential for optical and thermal-radiative contamination of the signal due to out-of-field

Abstract:

Advanced Encryption Standard (AES) is a widely accepted encryption algorithm used in Internet-of-Things (IoT) devices such as Bluetooth devices. Although the implementation of AES is complicated enough, attackers can still acquire the cryptographic information generated from the AES execution to perform Side-Channel Attack (SCA). There are two commonly used types of SCA, which are power based attack and Electromagnetic (EM) based attack. However, the acquisition of both power traces and EM near-field traces require close physical contact to the victim devices, which is difficult to attack a we

Abstract:

The effects of ionizing radiation on the breakdown voltage of p-channel power MOSFETs were examined through two-dimensional simulation.

These results provide insight into the breakdown performance of p-channel power MOSFETs in ionizing radiation environments, whose performance was found to be very different from corresponding n-channel power MOSFETs. Insights gained through analysis of p-channel devices suggest a terminatio

Abstract:

The effect of non-catastrophic human body model positive electrostatic discharge pulses on the radiation response of low power VDMOS N-channel transistors is explored. The effect of multiple pulses of HBM ESD is to cause a change in threshold-voltage shifts between stressed and non-stressed devices when exposed to Co₆₀ gamma radiation. This difference is due to the build-up of a space charge region next to the Si/SiO₂ interface. This space charge region reduces the net electric field across the gate oxide when biased with a positive voltage and thus reduces the formation of holes and interface

Abstract:

Uncertainties in radiative effects of the quarks in -background in the form of final state radiation (FSR) are significant when it comes to reducing all forms of systematics that can arise from measuring the jets energy. Analysis on FSR is in general conducted on different simulated samples where one has included the radiative effect using algorithms such as PYTHIA[29]. The hypothesis is that through the re-weighting of the -background nominal sample one could add a better representation of the FSR effect. Finding a simple way to include a better description of FSR would not only save time in

Recent research, however, has demonstrated that a calcium-activated K+-channel (hIK-channel) is activated by different types of ionizing radiation, e.g.

Also the structures are shown to retain a predominant austenite phase. Hardness increases by a factor of about 2.5 in both steels due largely to grain refinement and an introduction of a high density of dislocations.
