Construction Law, K. Brett Marston, J. Barrett Lucy Nov 2005

Construction Law, K. Brett Marston, J. Barrett Lucy

University of Richmond Law Review

Since the last survey of this topic published in the fall of 2000, construction law in Virginia has continued to evolve in an array of areas involving issues such as claims on surety bonds, claims against public entities, construction-related products like Exterior Insulation Finishing Systems ("EIFS"), and mechanic's liens. These changes have implicated and better defined legal principles including the "no damage for delay" clause on public contracts, requirements for privity in breach of warranty claims, and implied indemnification. The significant issues in construction law have arisen both in a number of significant judicial decisions, mostly from the Supreme Court …

Selective Object Stabilization For Home Video Consumers, Zailiang Pan, Chong-Wah Ngo Nov 2005

Selective Object Stabilization For Home Video Consumers, Zailiang Pan, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

This paper describes a unified approach for video stabilization. The essential goal is to stabilize image sequences that consist of moving foreground objects, which appear frequently in today's home videos captured by hand-held consumer cameras. Our proposed techniques mainly, rely on the analysis of;motion content. Three major components area initialization, segmentation and stabilization. In motion initialization, we propose a novel algorithm to efficiently search for the best possible frame in a sequence to start segmentation. Our segmentation algorithm is based on Expectation-Maximization (EM) framework which provides the mechanism for simultaneous estimation of motion models and their layers of support. Based …

Solids Flow Mapping In A High Pressure Slurry Bubble Column, Novica Rados, Ashfaq Shaikh, Muthanna H. Al-Dahhan Nov 2005

Solids Flow Mapping In A High Pressure Slurry Bubble Column, Novica Rados, Ashfaq Shaikh, Muthanna H. Al-Dahhan

Chemical and Biochemical Engineering Faculty Research & Creative Works

Successful Design and Scale-Up of Slurry Bubble Column Reactors (SBCRs) Require Proper Understanding of How Operating Conditions Affect their Flow Behavior. Presently, there is Little Information on the Flow Dynamics of Solids (E.g., Distribution of Velocities and Turbulent Parameters) in Slurry Systems that Are Operated at Industrially Relevant Conditions of High Pressure, High Superficial Gas Velocities, and High Solids Loading. Computer Automated Radio Particle Tracking (CARPT) is Widely Recognized as One of a Few Techniques that Can Be Reliably Used Even in Highly Turbulent and Opaque Slurry Flows. This Work Utilizes an Improved CARPT Technique to Investigate the Effect of …

Effects Of Ebg Reflection Phase Profiles On The Input Impedance And Bandwidth Of Ultrathin Directional Dipoles, M. Faisal Abedin, Mohammod Ali Nov 2005

Effects Of Ebg Reflection Phase Profiles On The Input Impedance And Bandwidth Of Ultrathin Directional Dipoles, M. Faisal Abedin, Mohammod Ali

Faculty Publications

A comprehensive study of the effects of the reflection phase profiles on dipole antennas is presented with the ultimate objective of designing ultrathin printed dipoles (as thin as one hundredth of the wavelength). Dipole driving-point impedance and bandwidth are studied as function of various electromagnetic bandgap (EBG) reflection phase profiles. It is demonstrated that although many different reflection phase profiles can be generated for a certain antenna height, it is the profile that satisfies a specific range of reflection phase angles that is required to achieve good antenna performance. Such optimum EBG phase profiles are generated for a number of …

Asynchronous Ds-Ss Cdma Random Spreading Code Correlation Statistics In The Presence Of Timing Error, David W. Matolak Nov 2005

Asynchronous Ds-Ss Cdma Random Spreading Code Correlation Statistics In The Presence Of Timing Error, David W. Matolak

Faculty Publications

We quantify the effect of timing tracking errors upon 2nd order correlation statistics of random binary spreading codes and, in so doing, fill a gap in the literature. Using a Gaussian model for timing tracking error, new expressions for autocorrelation statistics are derived. For crosscorrelations, we show that a zero mean Gaussian timing error has no effect upon 2nd order crosscorrelation statistics.

Getting Ready For A Nuclear-Ready Iran, Henry D. Sokolski Mr., Patrick Clawson Mr. Nov 2005

Getting Ready For A Nuclear-Ready Iran, Henry D. Sokolski Mr., Patrick Clawson Mr.

Books, Monographs & Collaborative Studies

As Iran edges closer to acquiring a nuclear bomb and its missiles extend an ever darker diplomatic shadow over the Middle East and Europe, Iran is likely to pose three threats. First, Iran could dramatically up the price of oil by interfering with the free passage of vessels in and through the Persian Gulf as it did during the l980s or by threatening to use terrorist proxies to target other states' oil facilities. Second, it could diminish American influence in the Gulf and Middle East by increasing the pace and scope of terrorist activities against Iraq, Saudi Arabia, other Gulf …

Elasticity Of Planar Fiber Networks, Xiangfa Wu, Yuris A. Dzenis Nov 2005

Elasticity Of Planar Fiber Networks, Xiangfa Wu, Yuris A. Dzenis

Department of Engineering Mechanics: Faculty Publications

A micromechanics model is proposed for the elasticity of planar fiber networks (FNs). The FN is created by random deposition of linearly elastic straight rods within a region. The rods are bonded rigidly at contacts. Under external in-plane loading, the FN deformation consists of fiber bending, elongation, and contraction. An effective constitutive relation for fiber network is developed by averaging the strain energy dissipated by all possible fiber deformations in all directions. Numerical calculations are performed to analyze the effects of fiber aspect ratio and fiber concentration on the effective stiffness of the planar random FN. Finite element analysis (FEA) …

Effects Of Gramicidin-A On The Adsorption Of Phospholipids To The Air–Water Interface, Samares C. Biswas, Shankar B. Rananavare, Stephen B. Hall Nov 2005

Effects Of Gramicidin-A On The Adsorption Of Phospholipids To The Air–Water Interface, Samares C. Biswas, Shankar B. Rananavare, Stephen B. Hall

Chemistry Faculty Publications and Presentations

Prior studies suggest that the hydrophobic surfactant proteins, SP-B and SP-C, promote adsorption of the lipids in pulmonary surfactant to an air–water interface by stabilizing a negatively curved rate-limiting structure that is intermediate between bilayer vesicles and the surface film. This model predicts that other peptides capable of stabilizing negative curvature should also promote lipid adsorption. Previous reports have shown that under appropriate conditions, gramicidin-A (GrA) induces dioleoyl phosphatidylcholine (DOPC), but not dimyristoyl phosphatidylcholine (DMPC), to form the negatively curved hexagonal-II (HII) phase. The studies reported here determined if GrA would produce the same effects on adsorption of DMPC and …

Detection Of Covert Channel Encoding In Network Packet Delays, Vincent Berk, Annarita Giani, George Cybenko Nov 2005

Detection Of Covert Channel Encoding In Network Packet Delays, Vincent Berk, Annarita Giani, George Cybenko

Computer Science Technical Reports

Covert channels are mechanisms for communicating information in ways that are difficult to detect. Data exfiltration can be an indication that a computer has been compromised by an attacker even when other intrusion detection schemes have failed to detect a successful attack. Covert timing channels use packet inter-arrival times, not header or payload embedded information, to encode covert messages. This paper investigates the channel capacity of Internet-based timing channels and proposes a methodology for detecting covert timing channels based on how close a source comes to achieving that channel capacity. A statistical approach is then used for the special case …

H-Infinity Estimation For Fuzzy Membership Function Optimization, Daniel J. Simon Nov 2005

H-Infinity Estimation For Fuzzy Membership Function Optimization, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

Given a fuzzy logic system, how can we determine the membership functions that will result in the best performance? If we constrain the membership functions to a specific shape (e.g., triangles or trapezoids) then each membership function can be parameterized by a few variables and the membership optimization problem can be reduced to a parameter optimization problem. The parameter optimization problem can then be formulated as a nonlinear filtering problem. In this paper we solve the nonlinear filtering problem using H∞ state estimation theory. However, the membership functions that result from this approach are not (in general) sum normal. …

Intellectual Property, Trade & Development: The State Of Play, Daniel J. Gervais Nov 2005

Intellectual Property, Trade & Development: The State Of Play, Daniel J. Gervais

Vanderbilt Law School Faculty Publications

This Article considers, first, available economic, social, and cultural analyses of the impact of intellectual property protection in developing countries. Economics provides a useful set of analytical tools and are directly relevant, in particular since the successfully arranged marriage of IP and trade rules after which it became inevitable that IP rules would be measured using an economic yardstick. The Paper also considers the claim that making proper intellectual property policy is impossible or inherently unreliable because theoretical models are inadequate or valid empirical data unavailable. Against this backdrop, the Article then examines the emergence of the World Trade Organization …

The Individual As Polluter, Michael P. Vandenbergh Nov 2005

The Individual As Polluter, Michael P. Vandenbergh

Vanderbilt Law School Faculty Publications

Individuals are the largest source ofdioxin emissions, contribute almost one-third ofall ozone precursor emissions, and are afar larger source of several other air toxics than all large industrial sources combined. Thus, after more than 30 years ofregulation largely directed at industry, individual behavior has emerged as a leading source ofpollution. Prof Michael P. Vandenbergh argues that treating individual behavior as a discrete source of pollution can lead to the development of viable, innovative regulatory instruments that have the prospect of achieving pollution reductions at a relatively low cost. The creation ofan individual toxic release inventory, for example, is one such …

Coordinated Cluster/Double Star Observations Of Dayside Reconnection Signatures, M. W. Dunlop, M. G. G. T. Taylor, J. A. Davies, C. J. Owen, F. Pitout, A. N. Fazakerley, K. Nykyri, Et Al. Nov 2005

Coordinated Cluster/Double Star Observations Of Dayside Reconnection Signatures, M. W. Dunlop, M. G. G. T. Taylor, J. A. Davies, C. J. Owen, F. Pitout, A. N. Fazakerley, K. Nykyri, Et Al.

Publications

The recent launch of the equatorial spacecraft of the Double Star mission, TC-1, has provided an unprecedented opportunity to monitor the southern hemisphere dayside magnetopause boundary layer in conjunction with northern hemisphere observations by the quartet of Cluster spacecraft. We present first results of one such situation where, on 6 April 2004, both Cluster and the Double Star TC-1 spacecraft were on outbound transits through the dawnside magnetosphere. The observations are consistent with ongoing reconnection on the dayside magnetopause, resulting in a series of flux transfer events (FTEs) seen both at Cluster and TC-1, which appear to lie north and …

Scalable Energy-Efficient Location-Aided Routing (Selar) Protocol For Wireless Sensor Networks, George Lukachan Nov 2005

Scalable Energy-Efficient Location-Aided Routing (Selar) Protocol For Wireless Sensor Networks, George Lukachan

USF Tampa Graduate Theses and Dissertations

Large-scale wireless sensor networks consist of thousands of tiny and low cost nodes with very limited energy, computing power and communication capabilities. They have a myriad of possible applications. They can be used in hazardous and hostile environments to sense for deadly gases and high temperatures, in personal area networks to monitor vital signs, in military and civilian environments for intrusion detection and tracking, emergency operations, etc. In large scale wireless sensor networks the protocols need to be scalable and energy-efficient. Further, new strategies are needed to address the well-known energy depletion problem that nodes close to the sink node …

Social Utility Functions-Part I: Theory, Wynn C. Stirling Nov 2005

Social Utility Functions-Part I: Theory, Wynn C. Stirling

Faculty Publications

The dominant approaches to utility-based multiagent decision theory rely on the premise of individual rationality-the doctrine that each individual is committed to achieving the best outcome for itself, regardless of the effect doing so has on others. This fundamentally asocial concept is the basis of conventional von Neumann-Morgenstern (vN-M) utilities but is inadequate to characterize truly cooperative artificial systems. Social utility functions differ from conventional vN-M utilities in that they are functions of multiple decision-maker preferences, rather than actions, and thus permit individuals to expand their spheres of interest beyond the self. A logical basis for coherent reasoning in multiagent …

China's Changing Economic Structures And Its Implications For Regional Patterns Of Trade Production And Integration, Kim Song Tan, Hoe Ee Khor Nov 2005

China's Changing Economic Structures And Its Implications For Regional Patterns Of Trade Production And Integration, Kim Song Tan, Hoe Ee Khor

Research Collection School Of Economics

There is tremendous momentum for economic and financial integration in East Asia today. Partly inspired by the formation of the European Union and partly as a response to the 1997/98 Asia financial crisis, many East Asian countries are showing greater commitment to regional economic cooperation. A number of bilateral free trade agreements (FTAs) have either been concluded or are being negotiated.1 At a less formal level, the ASEAN+3 grouping has brought the whole region together in regular consultations over trade, investment, as well as monetary and exchange rate policy matters.

Rhamnolipids Modulate Swarming Motility Patterns Of Pseudomonas Aeruginosa, Nicky C. Caiazza, Robert M. Q. Shanks, G. A. O'Toole Nov 2005

Rhamnolipids Modulate Swarming Motility Patterns Of Pseudomonas Aeruginosa, Nicky C. Caiazza, Robert M. Q. Shanks, G. A. O'Toole

Dartmouth Scholarship

Pseudomonas aeruginosa is capable of twitching, swimming, and swarming motility. The latter form of translocation occurs on semisolid surfaces, requires functional flagella and biosurfactant production, and results in complex motility patterns. From the point of inoculation, bacteria migrate as defined groups, referred to as tendrils, moving in a coordinated manner capable of sensing and responding to other groups of cells. We were able to show that P. aeruginosa produces extracellular factors capable of modulating tendril movement, and genetic analysis revealed that modulation of these movements was dependent on rhamnolipid biosynthesis. An rhlB mutant (deficient in mono- and dirhamnolipid production) and …
