Experimental Investigation Into The Boundary Layer Of A Robotic Anguilliform Propulsor, Jonathan R. Eastridge
LSU New Orleans Theses and Dissertations
Boundary layer information local to three longitudinal positions has been characterized for a 130 cm long biomimetic self-propulsor known as NEELBOT-1.1 that swims with undulatory anguilliform-like motions, via analysis of stereo particle image velocimetry (PIV) measurements for key moments in the undulation cycle and for numerous combinations of swimming conditions and motion parameters, ideal and non-ideal. No obvious turbulent flow structures or indications of boundary layer separation were observed at nonzero advance speeds, and skin friction coefficients were subsequently estimated for magnitude relative to the dynamic pressure associated with operation at the design swimming speed of Uo = 0.25 …

As such understanding and exploiting their dynamics both as isolated devices and members of coupled systems has been the subject of intensive investigation for more than a century. The advent of optomechanical resonators (OMRs) that support strong coupling between optical and mechanical modes resulting in self-sustained optomechanical oscillations, has created new opportunities for device development and implementation of coupled oscillatory systems. One aspect of this thesis is focused on exploring some of the unique features of OMRs and optomechanical oscillators (OMOs) that can be exploited …
Generation Of Correlated Dual Frequency Combs With Pm Fiber Lasers For High-Precision Metrology, Hanieh Afkhamiardakani
Generation Of Correlated Dual Frequency Combs With Pm Fiber Lasers For High-Precision Metrology, Hanieh Afkhamiardakani
Optical Science and Engineering ETDs
Intracavity Phase Interferometry (IPI) using two correlated, counter-propagating frequency combs (pulse trains) in mode-locked lasers has evolved into a powerful technique for high-precision metrology. In this method a physical parameter to be measured imparts a phase shift onto a pulse circulating in the laser cavity. Inside a laser cavity, that phase shift becomes a frequency shift (phase shift/round-trip time) applied to the whole frequency comb created by this pulse as it exits the cavity at each round-trip. This frequency shift is measured by interfering this comb with a reference comb created by a reference pulse circulating in the same mode-locked …

Radiation-Balanced Fiber Lasers And Amplifiers, Esmaeil Mobini Souchelmaei Mr
Optical Science and Engineering ETDs
Over the past decades, high-power fiber lasers and amplifiers have been extensively under research to achieve higher output powers. However, temperature rise in the core of fiber lasers and amplifiers has been a big issue in power-scaling. Radiation-balancing is a viable technique introduced for effective heat mitigation in lasers and amplifiers by S. Bowman in 1995. Radiation-balancing relies on solid-state laser cooling as a self-cooling mechanism to mitigate the generated heat in lasers and amplifiers. To implement the mentioned idea in fiber lasers and amplifiers, a set of issues should be scrutinized; (i) the amenability of silica glass (as the …

Development Of Water Coning Control Design Metrics In Naturally Fractured Reservoirs, Samir Prasun
Development Of Water Coning Control Design Metrics In Naturally Fractured Reservoirs, Samir Prasun
LSU Doctoral Dissertations
Naturally fractured reservoirs (NFRs) with bottom-water are known for their instant water breakthrough and severe water coning that reduces oil recovery. This is because water channels through the highly permeable fractures easily connecting the well to the aquifer bypassing the oil contained in the matrix. Remedial techniques such as producing below critical-oil rate, optimizing the well spacing and installing the downhole water sink (DWS)/ downhole water loop (DWL) technology, have already been successfully tested in single-porosity reservoirs (SPR). However, applicability of these techniques in NFRs are unknown since only a few studies have been performed on their feasibility in NFRs, …

Residential Seismic Retrofit Cost For Home Located In Tustin, California, Sara Clark
Construction Management
Seismically retrofitting a residential home not only protects the homeowner, but also helps them prepare for the future. Needless to say, many older homes are not up to the 2018 International Residential Code. As a result, many owners are uninformed about how much it will cost to retrofit their home and what changes will have to be made. The solution for this is determining a cost per square foot ratio that will help homeowners calculate an estimate for the retrofit of their home. Additionally, it is important to break this cost down into what specific changes need to be made. …

Application Of Monte Carlo (Mc) Method And Unscented Transformation (Ut) Method Into Trajectory Prediction Of A Dropped Cylinder In Two Dimensions, Yi Li
LSU New Orleans Theses and Dissertations
Monte Carlo (MC) method is one of the commonly used methods to study stochastic statistical problems in the field of marine engineering. There is no doubt that MC’s greatest advantage is its accuracy. However, as a method of using random numbers (or more common pseudo-random numbers) to solve calculation problems, its slow calculation speed is criticized, and its accuracy also depends on the selection of appropriate random times. The equations of the cylindrical motion with three degrees of freedom (surge, heave and pitch) in this article are formulated into a state space model. It is assumed that the small changes …
