Collective Effort, Private Accumulation: Constructing The Luxembourg Investment Fund, 1956-2019, Samuel Weeks

College of Humanities and Sciences Faculty Papers

In this chapter, I address capital accumulation by means of analyzing one of this process’s most economically successful administrative vehicles: the Luxembourg investment fund – which hosts, at present, nearly $5 trillion in assets. In the 1950s, officials from foreign investment companies came looking for an ultra-low-tax domicile from which to sell their “products.” However, Luxembourg’s long-used H29 holding company – a structure designed to avoid double (or any) taxation on the assets of rich foreign clients – would not work on its own as a vehicle for investment funds. Thus, local attorneys began to alter the H29 in piecemeal …

Blast Shock-Wave Characterization In Experimental Shock Tubes, Sudeepto Kahali

Dissertations

Blast-induced traumatic brain injuries have affected U.S. soldiers deployed for extended periods in the gulf and Afghanistan wars. To identify the biomechanical and biochemical mechanisms of injury, critical in the identification of diagnostic and therapeutic tools, compressed gas-driven shock tubes are used by investigators to study shockwave-animal specimen interactions and its biological consequences. However, shock tubes are designed and operated in a variety of geometry with a range of process parameters, and the quality of shock wave characteristics relevant to field conditions and therefore the study of blast-induced traumatic brain injuries suffered by soldiers is affected by those conditions.

Semantic, Integrated Keyword Search Over Structured And Loosely Structured Databases, Xinge Lu

Dissertations

Keyword search has been seen in recent years as an attractive way for querying data with some form of structure. Indeed, it allows simple users to extract information from databases without mastering a complex structured query language and without having knowledge of the schema of the data. It also allows for integrated search of heterogeneous data sources. However, as keyword queries are ambiguous and not expressive enough, keyword search cannot scale satisfactorily on big datasets and the answers are, in general, of low accuracy. Therefore, flat keyword search alone cannot efficiently return high quality results on large data with structure. …

Countering Internet Packet Classifiers To Improve User Online Privacy, Sina Fathi-Kazerooni

Dissertations

Internet traffic classification or packet classification is the act of classifying packets using the extracted statistical data from the transmitted packets on a computer network. Internet traffic classification is an essential tool for Internet service providers to manage network traffic, provide users with the intended quality of service (QoS), and perform surveillance. QoS measures prioritize a network's traffic type over other traffic based on preset criteria; for instance, it gives higher priority or bandwidth to video traffic over website browsing traffic. Internet packet classification methods are also used for automated intrusion detection. They analyze incoming traffic patterns and identify malicious …

Development Of Novel Membranes For Nanocarbon Enhanced Separation With Application In Biofuels And Solvent Recover, Oindrila Gupta

Dissertations

Pharmaceutical industries historically have had one of the highest amounts of solvent waste generated per unit of drug manufactured. Energy requirements and carbon footprint of current solvent recycling processes tend to be quite high, and the incineration of the solvents for waste disposal produces toxic air emissions. Also, rapidly increasing demand for energy and strict regulation on engine pollutant emissions have necessitated the use of alcohol as carbon-neutral fuels. Thermal distillation is one of the most common methods for the separation of alcohol-water mixtures. However, its application is limited due to energy requirements and high operating costs, and heating to …

Predicting Bulk-Scale Properties Of Pharmaceutical Powders From Their Particle-Scale Dimensionless Measures, Kuriakose T. Kunnath

Dissertations

Loose powder packing and flowability are both important bulk properties to consider in relation to pharmaceutical tablet and capsule manufacturing. These properties as well as cohesive powder agglomeration tendency impact the efficiency of various processes such as feeding, blending, conveying, and compaction, and could have an adverse effect on final drug product. Pharmaceutical powders are often milled to fine sizes (<100 gm) for dissolution improvements via increased available surface area. However, such particle size reductions lead to inadequate bulk powder properties due to high cohesion among the individual particles. Recent work has demonstrated the ability of nano-silica dry coating techniques to significantly decrease interparticle forces without changes in particle size. In this work, the ability to predict properties such as powder bed porosity, flowability, and particle agglomeration both before and after nano-silica dry coating is examined, along with assessment of the extent of property enhancements after dry coating. Previous studies have utilized empirical approaches to build property prediction models. However, such approaches lack physical fundamentals which dictate bulk powder behavior and would be unable to account for the effects of dry powder coating. Incorporation of physics can be done via computation of the granular Bond number, as is done in this study for a large dataset of commonly used pharmaceutical powders, with wide variations in particle size, shape, density, and surface roughness. Predictive capability of current Bond number models is investigated, reasons for outliers are elucidated, and amendments to improve prediction is attempted. Overall, the aim of this work is to expand generalizability of Bond number models to a wider variety of particles, and extend its use from single powders to multi-component mixtures. The major outcome of this work is the development of a predictive framework that is expected to simplify pharmaceutical dry powder formulation development, reduce required experimental testing, and provide quantifiable estimates to aid processing route decision making.

Alternative Item Selection Strategies For Improving Test Security In Computerized Adaptive Testing Of The Algorithm, Iwan Suhardi

REID (Research and Evaluation in Education)

One of the ability estimation methods that is widely applied to the Computerized Adaptive Testing (CAT) algorithm is the maximum likelihood estimation (MLE). However, the maximum likelihood method has the disadvantage of being unable to find a solution to the ability estimation of test-takers when the test takers' scores do not have a pattern. If there are test takers who get either score of 0 or perfect score, then the abilities of test-takers are usually estimated using the step-size model. However, the step-size model often results in item exposure where certain items will appear more often than other items. This …
