Effects of flow velocity and length-to-depth ratio on low-speed rectangular cavity flow oscillations for clean energy harvesting
No full textLow-speed cavity flow oscillations have been found to be a potential source for harvesting energy from flow-induced vibrations. An investigation was conducted using wind tunnel experiments to analyze the effect of flow velocity and cavity length-to-depth ratio on low-speed cavity flow oscillations. This study aims to find the most suitable cavity and flow velocity configuration to harvest clean oscillatory energy from the flow. Cavities with five length-to-depth (L/D) ratios of 1, 2, 3, 4 and 6 have been considered with flow velocities at 10, 15, 20, 25 and 30 m/s. The cavity tone amplitudes showed a general increase in amplitude with an increase in velocity up to 25 m/s and slightly dropped at 30 m/s, except for the cavity with L/D = 2. The Total Spreaded Acoustic Power (TSAP) was found to increase with an increase in velocity. The results showed that cavities with L/D = 1 and 6 do not exhibit cavity tones, and the noise in the frequency spectra was found to be broadband. Cavities with L/D = 2, 3 and 4 showed high-amplitude flow oscillations with frequencies that matched Rossiter’s semi-empirical model. Cavity with L/D = 3 showed flow oscillations with the highest amplitude, although the frequency peak of the cavity with L/D = 2 had a better Quality (Q) factor. Overall, the cavity with L/D = 3, at a flow velocity of 25 m/s, was found to be the best choice for energy harvesting.</p
Social rights and economics : claims to health care and education in developing countries
No full textThe author analyzes contemporary rights-based and economic approaches to health care and education in developing countries. He assesses the foundations and uses of social rights in development, outlines an economic approach to improving health and education services, and then highlights the differences, similarities, and the hard questions that the economic critique poses for rights. The author argues that the policy consequences of rights overlap considerably with a modern economic approach. Both the rights-based and the economic approaches are skeptical that electoral politics and de facto market rules provide sufficient accountability for the effective and equitable provision of health and education services, and that further intrasectoral reforms in governance, particularly those that strengthen the hand of service recipients, are needed. There remain differences between the two approaches. Whether procedures for service delivery are ends in themselves, the degree of disaggregation at which outcomes should be assessed, the consequences of long-term deprivation, metrics used for making tradeoffs, and the behavioral distortions that result from subsidies are all areas where the approaches diverge. Even here, however, the differences are not irreconcilable, and advocates of the approaches need not regard each other as antagonists.Health Monitoring&Evaluation,Health Systems Development&Reform,Decentralization,Public Health Promotion,Early Child and Children's Health,Health Monitoring&Evaluation,Health Economics&Finance,Poverty Assessment,Agricultural Knowledge&Information Systems,Gender and Education
Coherency matrices for characterization of vector optical fields
No full textWe describe optical coherency matrices as a generalized method for characterizing the statistical properties of optical fields. We then use this formalism to classify optical fields, in terms of separability, and transfer of entropy between multiple degrees of freedom.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-12-01The student, Varun Ajit Kelkar, accepted the attached license on 2019-07-12 at 20:22.The student, Varun Ajit Kelkar, submitted this Thesis for approval on 2019-07-12 at 20:30.This Thesis was approved for publication on 2019-07-15 at 11:29.DSpace SAF Submission Ingestion Package generated from Vireo submission #14293 on 2020-02-28 at 17:34:54Made available in DSpace on 2020-03-02T22:28:39Z (GMT).

Determination of structural changes and phase transformations in boron carbide by static and dynamic studies
No full textRecent transmission electron microscopy results demonstrate that the failure of B4C is commensurate with the segregation of boron icosahedra embedded in amorphous carbon in 2–3 nm wide amorphous bands along the (113) lattice direction, in good agreement with our recent theoretical results. Boron carbide is generally composed of multiple polytypes of B4C which have the same primitive lattice parameters but differ from each other by the location of the boron and carbon atoms in the unit cells. The unit cells are formed by a 12-atom B12-nCn icosahedron and a 3-atom (C3-nBn) chain. Our theoretical results indicate that one polytype, B12(C3), whose formation is responsible for
the failure of the entire material. This anomalous and poorly understood glass-like behavior in boron carbide has been the subject of research since its discovery over 70 years ago. The characterization of disorder in hot pressed and powder boron carbide samples
is therefore of primary interest. The research work has focused on characterization techniques which can be used at a micrometric sampling size so that individual powder grains of the material can be utilized. Specifically, micro-Raman and electrical
conductivity measurements can be used with micrometric gap cells to understand the disorder in B4C.The results also demonstrate that it is possible to induce transformations in boron carbide using electric fields that are comparable with those obtained under shock and nanoindentation. Our calculations present a hypothesis which can provide a solution to prevent the
premature failure of B4C. A route to achieve suppression of the B12(CCC) polytype without significantly affecting the elastic constants is via low concentration Silicon (Si) doping of B4C. Suppression of B12(CCC) by Si doping has implications towards
development of boron carbide armor with improved properties for protection against high velocity threats. In order to achieve this, nanostructures (nanowires, nanorods, etc.) of Sidoped boron carbide have been synthesized using a Solid-Liquid-Solid (SLS) growth
mechanism. The resulting structures have been characterized by SEM, TEM and Raman
spectroscopy and consolidated to evaluate their mechanical properties. In addition, the application of nanowires in a transparent and thermally conducting nanocomposite is demonstrated.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Varun Gupt
