Fault-tolerance embedding of rings and arrays in star and pancake graphs
The star and pancake graphs are useful interconnection networks for connecting processors in a parallel and distributed computing environment. The star network has been widely studied and is shown to possess attactive features like sublogarithmic diameter, node and edge symmetry and high …

Pseudomonas spp. Isolated from Soybean Nodules Promote Soybean Growth and Nitrogen Fixation
… strains (referred to in this study as Bullseye, Pancake, and Starfish) and an uninoculated control. Soybeans were harvested at two time points: the R2/R3 growth stage and the R6 growth stage. Following each harvest, measures of growth, yield, and nitrogen fixation were taken, and data were …

Computational modelling of the vortex state in high-temperature superconductors
… of the electromagnetic interaction between pancake vortices in the c-direction allows us to employ a meanfield method: all attractive inter-layer interactions are described by a substrate potential, which pancakes experience in addition to the in-layer pancake repulsion. Using an averaged …

Characterization of the mechanical properties of tactors used in tactile displays
Pancake motors used in a tactile display were analyzed to understand the characteristics of their operation, as well as to suggest improvements in the design of the display. The frequencies and forces produced by unencased and encased pancake motors were measured, and a motor model was formulated …

Growth and motion at the Weddell Sea ice edge
… The study sought to<br/>improve understanding of pancake ice in terms of dynamics, heat fluxes, ice growth rates and<br/>mechanisms.<br/>Ice motion at high frequencies was examined using GPS buoy positions at a 20-minute<br/>sampling interval. Relative motions of the buoy array were characterised …

Marketing the Myth: The Racial Commodification and Reclaiming of Aunt Jemima
… elements of print advertising, the Aunt Jemima pancake-box, and racist memorabilia intersect. In order to experiment with the topic, this thesis has adapted Yaeger’s theory of the “throwaway body,” and has applied it to the life cycle of the Aunt Jemima pancake box, with the acknowledgement that …

Stability and quench protection of high-temperature superconductors
… of the experimental work reported here, we used "pancake" coils wound with coated YBCO conductor, the HTS of choice by those currently developing HTS-based electric power devices, though, YBCO itself to date is still in the development phase. For protection against overheating, an HTS magnet …

A vibrotactile display design for the feedback of external prosthesis sensory information to the amputee wearer
… are presented including an array of vibrating pancake motors embedded into the exterior of a carbon fiber prosthetic socket and an array of vibrating pancake motors embedded into a silicone socket liner. Three haptic mappings were designed based on previous work in psychophysics, haptics, and …

Two graph problems: bidirectional heuristic search and the airplane seating assignment problem
… experiments are performed for IDD on the pancake problem, the sliding tile puzzle, and the Rubik's cube. Experiments for CBBS are performed on the pancake problem. Finally, experiments for FFGBS are performed on the pancake problem and DIMACS road networks. This dissertation introduces …

Microwave remote sensing of young sea ice in the Greenland Sea
… of young sea ice in the form of frazil and pancake ice. These young ice types have been implicated in the preconditioning of the ocean for deep ventilation. Satellite-borne microwave instruments potentially offer the ability to monitor important ice-cover parameters. A dataset consisting of …

Acoustic metamaterials comprised of dead-end pores and black hole effect for low frequency sound absorption in linear and nonlinear regimes
… a central perforation with a constant radius (pancake structure), while in the second the pore radius gradually decreases along the thickness of the absorber (profile structures). In the structures of the first type, the wave speed reduction is abrupt, while in the second a gradual impedance …

Investigating the air and liquid porosity of sea ice
… There are varying depths within an Antarctic pancake floe due to these dynamic conditions, yet the spatial variability of brine and air porosity profiles has not been previously investigated. Additionally, the sea ice brine phase is greatly influenced by temperature, yet similarly there are …

Evaluation of Leachate Chemistry from Coal Refuse Blended and Layered with Fly Ash
… better representation of field conditions is a "pancake layer" of ash above the refuse. A column study was initiated to evaluate the leachate chemistry from acid-forming refuse-ash bulk blends vs. ash over refuse layers. An acidic and an alkaline ash were blended with, or layered over, …

Physical and biogeochemical properties of seasonal sea ice in the Atlantic sector of the Antarctic marginal ice zone
… and spring, including measurements from young pancake ice, consolidated first-year ice and brash ice. It also proposes a revised set of standard operating procedures for conducting interdisciplinary sampling in complex marginal ice conditions. Measurements of sea-ice temperature, salinity, …

Atmospheric drivers of ice drift in the Antarctic marginal ice zone
… in July 2017. An initial 15- day analysis of pancake ice drift is presented, using the cluster of buoys, which shows: (1) exceptionally fast ice drift speeds and increased meandering of the buoys during cyclone activity; (2) high correlation of drift velocities with the surface wind …

Cenozoic extension superimposed on a Mesozoic thrust belt, central Nevada
… of younger extensional faults; The central Pancake Range underwent multiple episodes of Cenozoic extensional faulting. Fault sets generally strike N-S or NE-SW; one synvolcanic set strikes E-W. These normal fault sets: (1) form five temporally distinct episodes that correspond to regional …

Non-intrusive assessment of radionuclides in enclosed pipes and vessels
… Cesium 137 source placed inside. A Geiger-Muller pancake detector was used to measure gamma rays from several angular positions and at various axial distances along the outside of the pipe. A plot of the data showed excellent results despite the low efficiency of the detector. The data was run …

A tactile communication system for navigation
… and the efficacy of two types of motors (pancake and cylindrical) was compared. The arm display was tested with sedentary subjects in the laboratory, and the torso display was tested both in the laboratory with sedentary subjects and outdoors with active subjects. The results indicated …

Critical current anisotropy in high temperature superconductors
… FLL to a kinked lattice of strings and pancakes. The pinning force density for movement of strings inside the cuprate planes is considerably less than that on vortex pancake elements. When the FLL is entirely string-like this reduced pinning leads to the observed channelling minima. It …

Paleoenvironmental interpretation of the Guilmette Formation near Ely, Nevada
… a regressive phase noted in the Pancake Range that is not present in the Cherry Creek Range. The absence of this member in the Cherry Creek section may be a result of tectonic uplift initiated by onset of the Antler Orogeny. Transgression occurred during the Upper Givetian and …
