Although microgrids have the potential to solve several sticky problems that beset the present-day grid, indiscriminate application can cause serious problems. Thorough studies are needed on many aspects to identify the potential problems and to develop effective mitigation techniques. Microgrids can operate in parallel with the main grid or as an isolated system to support customers isolated from the grid. during parallel operations, the microgrid supplies only a fraction of the power demand of the grid. However, in islanded operations, the microgrid must continue to supply 100% of power to the customers. Both types of operations are studied to identify …

Geomorphology Of The Lake Shewa Landslide Dam, Badakhshan, Afghanistan, Using Remote Sensing Data, John F. Shroder Jr., Brandon J. Weihs Dec 2010

Geomorphology Of The Lake Shewa Landslide Dam, Badakhshan, Afghanistan, Using Remote Sensing Data, John F. Shroder Jr., Brandon J. Weihs

Geography and Geology Faculty Publications

Lake Shewa in northeastern Badakhshan, Afghanistan, was dammed sometime in antiquity when a large rock avalanche (sturzstrom) from the fault‐shattered and strongly weathered Archean gneisses of the Zirnokh peaks to the north moved into the Arakht River valley. This rock avalanche dammed up the river and its tributaries to a dam thickness of c. 400 m, producing a 12‐km‐long lake that is as much as 270 m deep, leaving c. 80 m of freeboard to the top of the dam. At least four separate instances of slope failure have been mapped at the site of the landslide dam, …

The Development Of A Phase Locked Wind Turbine Blade Finite Element Model To Predict Loads And Deflections During Fatigue Testing, Kyle Andrew Freeman Dec 2010

The Development Of A Phase Locked Wind Turbine Blade Finite Element Model To Predict Loads And Deflections During Fatigue Testing, Kyle Andrew Freeman

Master's Theses - Daytona Beach

Full scale blade testing provides blade manufacturers with quantitative data in order to assess blade design, manufacturing and durability. Structural testing is a requirement in order to design reliable blades, and to develop a further understanding of the dynamics involved in a modern turbine blade. Blade tests can be conducted in either a single axis or dual axis configurations. Historically, fatigue testing has been performed by utilizing forced displacement systems. These systems do not allow for the load phase angle to be controlled, and the maximum load application in the edge and flap directions are allowed to vary. The PhLEX …

Coupling Of Surge And Waves For An Ivan-Like Hurricane Impacting The Tampa Bay, Florida Region, Yong Huang, Robert H. Weisberg, Lianyuan Zheng Dec 2010

Coupling Of Surge And Waves For An Ivan-Like Hurricane Impacting The Tampa Bay, Florida Region, Yong Huang, Robert H. Weisberg, Lianyuan Zheng

Marine Science Faculty Publications

The interactions between waves and storm surge are investigated using an unstructured grid, coupled wave‐surge model forced by a hypothetical Ivan‐like hurricane impacting the Tampa Bay, Florida region. The waves derived from the unstructured version of the third‐generation wave model simulating waves nearshore. The surge derives from the unstructured Finite‐Volume Coastal Ocean Model, to which wave‐induced forces (based on radiation stress theory) are added to the traditional forces by winds and atmospheric pressure. Dependent upon complex bathymetry and geometry, the wave‐induced forces result in an additional 0.3∼0.5 m of surge relative to an uncoupled, surge‐only simulation, and the increase in …

We present a measurement of the top-quark width in the lepton+jets decay channel of tt̄ events produced in pp̄ collisions at Fermilab's Tevatron collider and collected by the CDF II detector. From a data sample corresponding to 4.3fb⊃-1 of integrated luminosity, we identify 756 candidate events. The top-quark mass and the mass of the hadronically decaying W boson that comes from the top-quark decay are reconstructed for each event and compared with templates of different top-quark widths (Γt) and deviations from nominal jet energy scale (ΔJES) to perform a simultaneous fit for both parameters, where ΔJES is used for the …
