An implementation of a reliable broadcast scheme for 802.11 using network coding

Creator:: Edgecombe, Richard
Abstract:: Forward Error Correction and retransmission are two approaches used to reliably broadcast data in a network with poor quality of service. Taking some assumptions, it has been suggested that a retransmission based reliable broadcasting scheme using network coding should in theory provide an increase in bandwidth efficiency by combining packets...

Model predictive control for sagittal plane locomotion

Creator:: Maunder, Cary R.
Abstract:: A distinct characteristic of legged locomotion is its periodic nature. This periodic motion, in the form of a periodic orbit, has been the target of many walking and running control strategies. The spring loaded inverted pendulum (SLIP) has become a popular model of sagittal plane locomotion, exhibiting behavior characteristic of...

Analysis of Surface Heat Flux Anomalies to Understand Recent Northeast Pacific Marine Heatwave Events

Creator:: Yi-Wei, Chen
Abstract:: Several large-scale marine heatwave events occurred during the last 10 years in the North Pacific. A particular extreme marine heatwave in the North Pacific called the blob created an unprecedented high peak of sea surface temperature (SST) during 2013/14. MHW events had significant impacts on downstream weather and precipitation patterns...

Overestimation of cloud cover in the MODIS cloud product

Creator:: Schuetz, Andrea M.
Abstract:: The operational processing of MODIS imagery to produce the MOD06 cloud product is based on the assumption that cloudy 1-km pixels are overcast. This assumption is examined using a partly cloudy pixel retrieval scheme, which allows for fractional cloud cover within the 1-km pixels. Cloud flags attached to 250-m MODIS...

Vertical Structure of the Lower Troposphere in a Changing Arctic

Creator:: Watkins, Daniel M.
Abstract:: The Arctic climate system is changing dramatically as a response to rising atmospheric greenhouse gas concentrations. Key indicators of Arctic change include thinning and retreating of Arctic pack ice, thawing permafrost, greening tundra, and rising surface temperatures. The structure of the atmospheric boundary layer influences and is influenced by processes...

Observational Analysis of Extratropical Cyclone Interactions with Northeast Pacific Sea Surface Temperature Anomalies

Creator:: Phillips, Briana K.
Abstract:: In 2013, a large upper-ocean thermal anomaly formed in the Gulf of Alaska (GOA) with sea surface temperatures (SSTs) warmer than 4 degrees Celsius above the climatological norm. This warm anomaly persisted for the next three years and has been linked to downstream effects on North American climate and negative...

Evaluation of the predictive capability of two-phase flow maps for microchannel condensation of R-134a at low mass flux conditions

Creator:: VanderPutten, Michael A.
Abstract:: Predicting condensation flow regimes and the associated heat transfer and pressure drop in microchannels is critical for designing terrestrial and space systems for heating, cooling, power generation, and advanced manufacturing. It is well established that in flows approaching the microscale (Dh < 1 mm) gravity-dominated flow regimes become less relevant,...

Heat transfer during the piston-cylinder expansion of a gas

Creator:: Rodrigues, Matthew Jose
Abstract:: The expansion of a gas within a piston-cylinder arrangement is studied in order to obtain a better understanding of the heat transfer which occurs during this process. While the situation of heat transfer during the expansion of a gas has received considerable attention, the process is still not very well...

Hybrid computational voxelization using the graphics pipeline

Creator:: Rauwendaal, Randall
Abstract:: This thesis presents an efficient computational voxelization approach that utilizes the graphics pipeline. Our approach is hybrid in that it performs a precise gap-free computational voxelization, employs fixed-function components of the GPU, and utilizes the stages of the graphics pipeline to improve parallelism. This approach makes use of the latest...

Relationship between tropical Atlantic Sea surface temperature variability and southern Indian Ocean tropical cyclones

Creator:: DeBlander, Evan F.
Abstract:: Recent studies have found that equatorial Atlantic sea surface temperature (SST) variability may be influencing tropical Indian Ocean climate (Kucharski 2009, Wang 2009). Due to the economic and social impact of tropical cyclones, it is important to investigate how an Atlantic-Indian Ocean connection may be affecting tropical cyclone behavior in...
