Rate selection for MIMO links
… links can support a set of much higher data rates than single-input single-output (SISO) links. However, it is not always optimal for a node to transmit at its largest supported rate. Depending on various factors, it may be more efficient for a node to transmit at one of its lower …

Bit-rate selection in wireless networks
This thesis evaluates bit-rate selection techniques to maximize throughput over wireless links that are capable of multiple bit-rates. The key challenges in bit-rate selection are determining which bit-rate provides the most throughput and knowing when to switch to another bit-rate that would …

Empirical Approch For Rate Selection In MIMO OFDM
… Group 802.11n to develop a standard for enhanced rate 802.11 based on OFDM using Multi Input/Multiple Output (MIMO) techniques. The most dominant proposal is the use of singular value decomposition based MIMO methods to achieve the high data rate. The selection of modulation and coding rates plays …

Low-complexity, low-regret link rate selection in rapidly varying wireless channels
… the problem of transmitting at the optimal rate over a rapidly varying wireless channel with unknown statistics when the feedback about channel quality is very limited. One motivation for this problem is that, in emerging wireless networks, the use of mmWave bands means that the channel …

Empirical Studies on Selection and Travel Performance of Eye-tracking in Virtual Reality
We presented two studies on VR selection and travel performances using eye-based interaction via FOVE head-mounted display (HMD). Our selection experiment was modelled after the ISO 9241-9 reciprocal selection task, with targets presented at varying depths in a custom virtual environment. We …

3D Electro-thermal Monte Carlo Study of Transport in confined Silicon Devices
… problems, including the ability to accurately simulate and predict the behavior of these devices, and to manage the heat they generate. This work uses a 3D Monte Carlo (MC) simulator to investigate the electro-thermal behavior of quasi-one-dimensional electron gas (1DEG) multigate …

Spinal codes
Spinal codes are a new class of rateless codes that enable wireless networks to cope with time-varying channel conditions in a natural way, without requiring any explicit bit rate selection. The key idea in the code is the sequential application of a pseudo-random hash function to the message bits, …

Reconfigurable Sampling for Enhanced Energy Efficiency in Power-Constrained Wireless Systems
… this technique reconfigures, in real time, the rate of data sampling based on the information content of the data acquired in the preceding step. Through this technique, significant reduction in energy usage and data load can be achieved, as is analytically and experimentally demonstrated in …

Development of a Design Tool for Rapid Gravity Media Filtration in Water Treatment
… water treatment design tool that incorporates a high-level filter design spreadsheet previously developed by Morrison (2019). This study presents guidelines to filter designers for the whole filtration process based on a literature review that consolidates key aspects and design …

Efficient flooding for wireless mesh networks
… quality. The mechanism includes a novel bit-rate selection algorithm that trades off the speed of high bit-rates against the larger number of nodes likely to receive low bit-rates. Unusually, UFlood uses both random network coding to increase the usefulness of each transmission and detailed …

Model-code separation architectures for compression based on message-passing
… Of interest to system designers, issues such as rate selection, doping, and code selection are addressed, and a method similar to EXIT-chart analysis is developed for evaluating when compression is possible. Suggestions for system interfaces and algorithmic factorization are distilled, and …

Coding in 802.11 WLANs
… only a limited choice of pre-speci¯ed coding rates is supported. These are implemented in hardware and thus di±cult to change, and the coding rates are selected with point to point operation in mind. This thesis is concerned with using FEC coding in 802.11 WLANs in more interesting ways that …

The dependence of CD4 T cell development and activation on the kinetics of the TCR:pMHC interaction
… interaction is determined by the ratio of the rate of dissociation: k<sub>off</sub>) and the rate of association: k<sub>on</sub>) between the TCR and the pMHC. The overall affinity of the complex must be sufficient for productive transmission of signals through the TCR to activate a T cell. …
