The motion and dissolution of bubbles in confined microgeometries is of pivotal importance for many natural and industrial flow processes such as microchemical systems and the development of models for unveiling the fundamentals of oil recovery in porous-like media. In this thesis, we experimentally study the formation, morphology, dynamics and mass transfer of bubbles flowing through a liquid in a microchannel with a particular emphasis on the behavior and dissolution of CO2 micro-bubbles in high viscosity oils. A significant part of the thesis addresses the initial dynamical behavior of dissolving CO2 monodisperse micro-bubbles in numerous solvents (water, silicone oils, alcohols, …

Learning The Intention Embedded In The Natural Language Texts: Focused Studies On Connotation And Deception, Song Feng

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In natural-language texts, certain information intended by the author, such as connotation, deception, sarcasm, humor, may not be stated explicitly. Recognizing such authorial intention is one of the keys to truly understanding human communications. There are rapidly increasing interests in uncovering the intention that is embedded in the textual content for real-life applications, such as opinion mining, deception detection, news-gathering, text generation, and educational testing. However, identifying the intended information computationally can be very challenging as it usually requires appropriate syntactic and semantic schemes for interpretations or inferences, and sometimes, the factor of the world knowledge. Previous work addressing authorial …

Toward A Patent Exhaustion Regime For Sustainable Development, 32 Berkeley J. Int'l Law. 330 (2014), Benjamin Liu

UIC Law Open Access Faculty Scholarship

This Article argues that the current exhaustion doctrine, when applied to the refurbishing industry, fails to balance its mandate of promoting technological progress with the broader program of sustainable development and is therefore unsuitable for countries on the modernization path. First, what constitutes an infringing “making” remains underdetermined. Second, the evidentiary hurdle for proving legal refurbishment is too onerous for the low margin and under-resourced refurbishing industry. Finally, the all-or-nothing approach to judging infringement fails to account for the nuanced cost-benefit nexus that exists between patentees, refurbishers, and society at large and discourages private ordering. To recalibrate the balance between …

Comparing Malaysian And Scottish Firms On Practices For Strategic Capability Management, K. Kanapathy, R. Dekkers

Research Publications (2011 to 2015)

The study of practices for Strategic Capacity Management at five Malaysian companies and four Scottish companies shows that the Malaysian manufacturing managers acted more reactive due to pressures by sales and processing orders, whereas the Scottish managers were implementing a manufacturing strategy more 'independently'. Problems with suppliers, albeit sometimes caused by outsourcing, feature high on the list of challenges in both samples. Alignment of organisational structures and investment in technologies are seen by all as key to aligning the manufacturing strategy with the competitive strategy, though actual investments tend to be happening more in Scottish companies.

Data Transport System, Rahav Dor

All Computer Science and Engineering Research

To facilitate the WU Smart Home research [21] we built a system that collects data from sensors and uploads the data to the cloud. The system supports data collection from multiple locations (typically apartments) that are independent from each other, endowing the system with two benefit: distributed data collection and alleviating privacy concerns. Each location is managed by a local micro-server (μServer) that is responsible for receiving data packets from sensors and managing their transient storage. Periodically the μServer triggers a data transport process that moves the data to a cloud server where it is stored in a centralized database. …

There is a strong clinical need for a more stable and effective sunscreen ingredient such …

A Pareto-Frontier Analysis Of Performance Trends For Small Regional Coverage Leo Constellation Systems, Christopher Alan Hinds

Master's Theses

As satellites become smaller, cheaper, and quicker to manufacture, constellation systems will be an increasingly attractive means of meeting mission objectives. Optimizing satellite constellation geometries is therefore a topic of considerable interest. As constellation systems become more achievable, providing coverage to specific regions of the Earth will become more common place. Small countries or companies that are currently unable to afford large and expensive constellation systems will now, or in the near future, be able to afford their own constellation systems to meet their individual requirements for small coverage regions.

The focus of this thesis was to optimize constellation geometries …
