LA SAFE – Louisiana’s Strategic Adaptations for Future Environments: The Collective Search for Common Ground
Get PDFIn coastal Louisiana, subsidence and sea level rise, plus the threat of hurricanes and flooding, combine to create one of the highest rates of relative sea level rise in the world (Penland & Ramsey, 1990). To help address these issues, the National Disaster Resilience Competition (NDRC), sponsored by the U.S. Department of Housing and Urban Development (HUD) and the Rockefeller Foundation, awarded funding for LA SAFE – Louisiana’s Strategic Adaptations for Future Environments. The LA SAFE program, a partnership between the Office of Community Development (OCD) and the Foundation for Louisiana (FFL), supported an inclusive public process to identify adaptation strategies to enhance the resilience of coastal Louisiana. This public process involved the six parishes most impacted by Hurricane Isaac in 2012: Jefferson, Lafourche, Plaquemines, St. John the Baptist, St. Tammany, and Terrebonne.
Throughout the planning and implementation process, UNO-CHART conducted an evaluation in an iterative manner that allowed for continual feedback. The evaluation was a mixed methods process that included both qualitative and quantitative measures, involving both process and outcome measures
Risk Assessment of Dropped Cylindrical Objects in Offshore Operations
Get PDFDropped object are defined as any object that fall under its own weight from a previously static position or fell due to an applied force from equipment or a moving object. It is among the top ten causes of injuries and fatality in oil and gas industry. To solve this problem, several in-house tools and guidelines is developed over time to assess the risk of dropped objects on the sub-sea structures. This thesis focuses on compiling and comparing those methods in hope to improve the recommended practices available in the market. A simple modification is done on the in-house tools to better predict the landing point distribution of the dropped cylindrical objects on the seabed by imposing the random three-dimensional rotation around the water depth axis. This tool is then used to compare the result of annual hit frequency using the recommended practice and further compared with the available experimental data
The Everyday Universe
Get PDFI take inspiration from ordinary objects and materials. Through photography, I attempt to transcend the familiar to discover complexity within the bits and pieces of my everyday life. Like other artistic representations, a photograph is a singular portrayal, not an actualization of physical reality. My artistic exploration of this involves incorporating elements of abstraction to point to the truth that all photographs are, by nature, an abstraction of our physical reality based on perspective. The resulting images often share a quality of impermanence, counterbalanced by the act of making a photographic document. By evoking this temporal quality of photography and abstracting familiar materials and surfaces, I aim to create a playful tension in my imagery
Visual Pleasure and Racial Ambiguity
Get PDFI struggle to present work that reflects a psychological expressivity which at the same time conveys intellectual concepts that are of concern to me. It seems that the fluidity of an image can communicate a certain pathos, and correspond to the fluid nature of one’s identity. Drippy paint, distorted bodies, and vertiginous video clips can give an indication about what a body feels like from within. Depictions of these bodily feelings help to communicate ideas about what it means to be alive in general, and a mixed race woman, in particular
Life in Balance: The Work-Life Balance Stories of Black Female School Leaders
Get PDFThe purpose of this study is to examine the work-life balance experiences of Black females school leaders. Due to the inherent intersectionality of race and gender that is experienced by Black females, a study of their unique experiences with work-life balance is valuable to the field of educational leadership. The responsibilities associated with school leadership positions are extensive and those school leaders who also have spouses and children must figure out a way to fulfill responsibilities associated with each role. Work-life balance is important to understand for school leaders whose career responsibilities may interact with those associated with their personal lives. The theoretical framework, Black Feminist Thought, guided the data collection and analysis processes, and provided the basis for the resulting narrative findings. This study gave voice to an otherwise silenced, marginalized group, Black female school leaders. All data was synthesized into narratives and from these narratives came six themes: (1) Familial Sacrifice; (2) Servant Leadership; (3) Informal and Formal Work-life Balance Policies; (4) Notion of Self-Care; (5) Upbringing and Black Females’ Prideful Identity; and (6) Black Females having to prove themselves. While this study does not show evidence of school leaders having achieves work-life balance, the findings will inform the practices of perspective Black female school leaders and add the voices of Black female school leaders to the literature on Black female school leader’s experiences with work-life balance
Dynamic Response of a Hingeless Helicopter Rotor Blade at Hovering and Forward Flights
Get PDFThe helicopter possesses the unrivaled capacity for vertical takeoff and landing which has made the helicopter suitable for numerous tasks such as carrying passengers and equipment, providing air medical services, firefighting, and other military and civil tasks. The nature of the aerodynamic environment surrounding the helicopter gives rise to a significant amount of vibration to its whole body. Among different sources of vibrations, the main rotor blade is the major contributor. The dynamic characteristics of the hingeless rotor consisting of elastic blades are of particular interest because of the strongly coupled equations of motion. The elastic rotor blades are subjected to coupled flapping, lead-lag, and torsional (triply coupled) deflections. Once these deflections exceed the maximum allowable level, the structural integrity of the rotor blade is affected leading to the ultimate failure. The maximum deflection that a blade can undergo for a specific operating condition needs to be estimated. Therefore, in this study, the triply coupled free and forced response of the Bo 105 hingeless, composite helicopter rotor blade is investigated at hovering and forward flights. At first, a model of the composite cross-section of the rotor blade is proposed for which a semi-analytical procedure is developed to estimate the sectional properties. These properties are used in the mathematical model of the free vibration of the rotor blade having the proposed cross-section to solve for the natural frequencies and the mode shapes. The aerodynamic loadings from the strip theory are used to estimate the time-varying forced response of the rotor blade for hovering and forward flights. The large flapping and inflow angles are introduced in the mathematical model of the forward flight and the corresponding nonlinear mathematical model requires a numerical solution technique. Therefore, a generalization of the method of lines is performed to develop a robust numerical solution in terms of time-varying deflections and velocities. The effect of the unsteady aerodynamics at the forward flight is included in the mathematical model to estimate the corresponding dynamic response. Both the analytical and the numerical models are validated by finite element results and the convergence study for the free vibration is performed
