Warm Water Formation And Escape In The Upper Tropical Atlantic Ocean - 1. A Literature Review, Sang-Ki Lee, G. T. Csanady

CCPO Publications

We review current understanding of the warm water formation and escape process in the tropical Atlantic Ocean and point out the physical aspects of the process not yet fully explored. From this review, we found a need for a simple model capable of describing the first-order heat and mass balance in the tropical Atlantic Ocean. This line of work is continued in part 2 [Lee and Csanady, this issue]. Copyright 1999 by the American Geophysical Union.


Modeling The Effects Of Doliolids On The Plankton Community Structure Of The Southeastern Us Continental Shelf, A. G. Edward Haskell, Eileen E. Hofmann, Gustav-Adolf Paffenhofer, Peter G. Verity Jan 1999

Modeling The Effects Of Doliolids On The Plankton Community Structure Of The Southeastern Us Continental Shelf, A. G. Edward Haskell, Eileen E. Hofmann, Gustav-Adolf Paffenhofer, Peter G. Verity

CCPO Publications

A model of the lower trophic levels that consists of a system of coupled ordinary differential equations was developed to investigate the time-dependent behavior of doliolid populations associated with upwelling features on the outer southeastern US continental shelf. Model equations describe the interactions of doliolids with two phytoplankton size fractions, five copepod developmental stages and a detrital pool. Additional equations describe nitrate and ammonia. Model dynamics are based primarily upon data obtained from field and laboratory experiments for southeastern US continental shelf plankton populations. Variations on a reference simulation, which represents average upwelling conditions without doliolids, were carried out to …

Revenue Equivalence Of Leveled Commitment Contracts, Tuomas Sandholm, Yunhong Zhou Jan 1999

Revenue Equivalence Of Leveled Commitment Contracts, Tuomas Sandholm, Yunhong Zhou

All Computer Science and Engineering Research

In automated negotiation systems consisting of self-interested agents, contracts have traditionally been binding. Leveled commitment contracts - i.e. contracts where each party can decommit by paying a predetermined penalty - were recently shown to improve expected social welfare even if agents decommit insincerely in Nash equilibrium. Such contracts differ based on whether agents have to declare their decommitting decisions sequentially or simultaneously, and whether or not agents have to pay the penalties if both decommit. For a given contract, these protocols lead to different decommitting thresholds and probabilities. However, this paper shows that, surprisingly, each protocol leads to the same …


Bargaining With Deadlines, Tuomas Sandholm, Nir Vulkan Jan 1999

Bargaining With Deadlines, Tuomas Sandholm, Nir Vulkan

All Computer Science and Engineering Research

This paper analyzes automated distributive negotiation where agents have firm deadlines that are private information. The agents are allowed to make and accept offers in any order in continuous time. We show that the only sequential equilibrum outcome is the one where the agents wait until the first deadline, at which point that agent concedes everything to the other. This holds for pure and mixed strategies. So, interestingly, rational agents can never agree to a nontrivial split because offers signal enough weakness of bargaining power (early deadline) so that the recipient should never accept. Similarly, the offerer knows that it …


The Design And Performance Of A Pluggable Protocols Framework For Object Request Broker Middleware, Fred Kuhns, Carlos O'Ryan, Douglas C. Schmidt, Jeff Parsons Jan 1999

The Design And Performance Of A Pluggable Protocols Framework For Object Request Broker Middleware, Fred Kuhns, Carlos O'Ryan, Douglas C. Schmidt, Jeff Parsons

All Computer Science and Engineering Research

To be an effective platform for performance-sensitive real-time and embedded applications, off-the-shelf OO middleware like CORBA, DCOM, and Java RMI must preserve communication-layer quality of service (QoS) properties to applications end-to-end. However, conventional OO middleware interoperability protocols, such as CORBA's GIOP/IIOP or DCOM's MS-RPC, are not well suited for applications that cannot tolerate the message footprint size, latency, and jitter associated with general-purpose messaging and transport protocols. It is essential, therefore, to develop standard plugable protocols frameworks that allow custom messaging and transport protocols to be configured flexibly and used transparently by applications. This paper provides three contributions to research …

This is used as a vehicle for studying the key design issues that must be resolved to allow active networking to become a mainstream technology.


Optimal Flow Aggregation, Subhash Suri, Tuomas Sandholm, Priyank Warkhede Jan 1999

Optimal Flow Aggregation, Subhash Suri, Tuomas Sandholm, Priyank Warkhede

All Computer Science and Engineering Research

Current IP routers are stateless: they forward individual packets based on the destination address contained in the packet header, but maintain no information about the application or flow to which a packet belongs. This stateless service model works well for best effort datagram delivery, but is grossly inadequate for applications that require quality of service guarantees, such as audio, video, or IP telephony. Maintaining state for each flow is expensive because the number of concurrent flows at a router can be in the hundreds of thousands. Thus, stateful solutions such as Intserv (integrated services) have not been adopted for their …


Tracking Mobile Units For Dependable Message Delivery, Amy L. Murphy, Gruia-Catalin Roman, George Varghese Jan 1999

Tracking Mobile Units For Dependable Message Delivery, Amy L. Murphy, Gruia-Catalin Roman, George Varghese

All Computer Science and Engineering Research

As computing components get smaller and people become accustomed to having computational power at their disposal at any time, mobile computing is developing as an important research area. One of the fundamental problems in mobility is maintaining connectivity through message passing as the user moves through the network. An approach to this is to have a single home node constantly track the current location of the mobile unit and forward messages to this location. One problem with this approach is that during the update to the home agent after movement, messages are often dropped, especially in the case of frequent …


A Fine-Grained Model For Code Mobility, Cecilia Mascolo, Gian Pietro Picco, Gruia-Catalin Roman Jan 1999

A Fine-Grained Model For Code Mobility, Cecilia Mascolo, Gian Pietro Picco, Gruia-Catalin Roman

All Computer Science and Engineering Research

In this paper, we take the extreme view that every line of code is potentially mobile, i.e., may be duplicated and/or moved from one program context to another on the same host or across the network. Our motivation is to gain a better understanding of the range of constructs and issues facing the designer of a mobile code system, in a setting that is abstract and unconstrained by compilation and performance considerations traditionally associated with programming language design. Incidental to our study is an evaluatoin of the expressive power of Mobile UNITY, a notation and proof logic for mobile computing.


Frequency Domain Robustness Analysis Of Hopfield And Modified Hopfield Neural Networks, Jie Shen, S. N. Balakrishnan Jan 1999

Frequency Domain Robustness Analysis Of Hopfield And Modified Hopfield Neural Networks, Jie Shen, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A variant of Hopfield neural network, called the modified Hopfield network, is formulated in this study. This class of networks consists of parallel recurrent networks which have variable dimensions that can be changed to fit the problem under consideration. It has a structure to implement an inverse transformation that is essential for embedding optimal control gain sequences. Equilibrium solutions of this network are discussed. The robustness of this network and the classical Hopfield network are carried out in the frequency domain using describing functions

Response Of Tall Fescue To Saline Water As Influenced By Leaching Fractions And Irrigation Uniformity Distributions, Algirdas M Leskys Jan 1999

Response Of Tall Fescue To Saline Water As Influenced By Leaching Fractions And Irrigation Uniformity Distributions, Algirdas M Leskys

UNLV Retrospective Theses & Dissertations

Research was conducted to determine the impact leaching fractions (LF = drainage volume divided by irrigation volume) and irrigation uniformity distributions have on the response of tall fescue to irrigation with saline water. Tall fescue (Festuca arundinacea Schreb. 'Monarch') was grown in 18 plots, each with a centrally located lysimeter that enabled estimates of evapotranspiration and irrigation requirements. Imposed treatments included setting LFs at 0.05, 0.15, or 0.25 and manipulating plot irrigation systems such that Christiansen Uniformity Coefficients (CUC) were set at 0.65, 0.75, or 0.85. Saline irrigation water (2.5 dS m{dollar}\sp{-1}{dollar}) was applied for an 18-month period. Significant LF …

Room-Temperature Blue Luminescence Of Thermally Oxidized Si1-X-YGeXCY Thin Films On Si (100) Substrates, Xuemei Cheng, Youdou Zheng, Xiabing Liu, Lan Zang, Zhiyun Lo, Shunming Zhu, Ping Han, Ruolian Jiang

Physics Faculty Research and Scholarship

We measured at room temperature the photoluminescence spectra of the thermally oxidized Si1-x-yGexCy thin films which were grown on silicon substrates by plasma-enhanced chemical vapor deposition and the wet oxidized at 1100 °C for 20 min. The photoluminescence band with a peak at ~393 nm under the exciting radiation of λ = 241 nm was observed. Possible mechanism of this photoluminescence is discussed.


Population Trapping In Extremely Highly Excited States In Microwave Ionization, Michael W. Noel, W. M. Griffith, T. F. Gallagher Jan 1999

Population Trapping In Extremely Highly Excited States In Microwave Ionization, Michael W. Noel, W. M. Griffith, T. F. Gallagher

Physics Faculty Research and Scholarship

When a lithium atom in a Rydberg state (n 􏰟 80) is exposed to a short, intense microwave pulse we find that substantial population is left in extremely highly excited states (n . 120), in spite of the fact that the microwave field amplitude is more than 40 times larger than required to classically ionize these states.


Paleoclimatic Significance Of Insoluble Microparticle Records From Canadian Arctic And Greenland Ice Cores, Christian Michel Zdanowicz Jan 1999

Paleoclimatic Significance Of Insoluble Microparticle Records From Canadian Arctic And Greenland Ice Cores, Christian Michel Zdanowicz

Doctoral Dissertations

The past and present variability of climate in the Arctic region is investigated using ice core records of atmospheric dust (microparticles) and volcanic aerosols developed from the Canadian Arctic and Greenland. A high-resolution, 10 4-year long proxy record of atmospheric dust deposition is developed from an ice core (P95) drilled through the Penny Ice Cap, Baffin Island. Snowpit studies indicate that dust deposited on the Penny Ice Cap are representative of background mineral aerosol, and demonstrate that the variability of dust fallout is preserved in the P95 core at multi-annual to longer time scales. The P95 dust record reveals a …


Design And Code Generation Concepts For Statechart Diagrams Of The Uml V1.1 In Concurrent Environments, Pierre Metz Jan 1999

Design And Code Generation Concepts For Statechart Diagrams Of The Uml V1.1 In Concurrent Environments, Pierre Metz

Theses

This thesis deals with code generation concepts for the statechart diagrams of the UML vl.l. It explores implementation approaches for mapping statechart diagrams to code. It also focuses on modelling rules for consistent design of dynamic object behaviour. Most of the given object-oriented (00) methods have statechart diagrams as their centre. It is proposed to use statechart diagrams to model the internal behaviour of objects and lifecycles, respectively. Generally, statechart diagrams are used in the area of analysis and design of reactive systems such as realtime- and embedded-systems. This thesis introduces different existing implementation patterns and shows how they can …


The Predictability Of Punitive Damages Awards In Published Opinions, The Impact Of Bmw V. Gore On Punitive Damages Awards, And Forecasting Which Punitive Awards Will Be Reduced, Theodore Eisenberg, Martin T. Wells Jan 1999

The Predictability Of Punitive Damages Awards In Published Opinions, The Impact Of Bmw V. Gore On Punitive Damages Awards, And Forecasting Which Punitive Awards Will Be Reduced, Theodore Eisenberg, Martin T. Wells

Cornell Law Faculty Publications

This article assesses the relation between compensatory damages and punitive damages in cases leading to published opinions and BMW v. Gore's impact on the patterns of punitive damages awards in these opinions. We find that punitive damages awards are considerably higher in cases leading to published opinions than in trial level cases. But the correlation between compensatory and punitive awards found in trial level data persists in published opinions and is all but indistinguishable from the correlation in trial level data. We find no significant difference in the pattern of awards before and after BMW and no significant difference …


Judicial Decisionmaking In Federal Products Liability Cases, 1978-1997, Theodore Eisenberg Jan 1999

Judicial Decisionmaking In Federal Products Liability Cases, 1978-1997, Theodore Eisenberg

Cornell Law Faculty Publications

In 1992, Professor James Henderson and I wrote that, throughout the 1980s, a quiet, pro-defendant revolution in products liability had occurred. That revolution was likely largely the product of a "widespread, independent shift in judicial attitudes." It was not discernable in cases tried before juries. The federal data used in that study were available through 1989. Also in 1992, using the same database, Professor Kevin Clermont and I wrote about the surprising relation between plaintiff win rates in judge and jury trials in products liability cases. Plaintiffs prevailed at a higher rate before judges than they did before juries. Comparable …

Analysis Of Non-Linear Formation Fracture Resistance Tests Obtained During Oil Well Drilling Operations., Gursat Altun Jan 1999

Analysis Of Non-Linear Formation Fracture Resistance Tests Obtained During Oil Well Drilling Operations., Gursat Altun

LSU Historical Dissertations and Theses

A leak-off test (LOT), commonly known as formation pressure integrity test (PIT), is a verification method to estimate the fracture pressure of exposed formations. After cementing each casing string, a LOT is run to verify that the casing, cement, and formation below the casing seat can withstand the wellbore pressure required to drill safely to the next casing setting depth. Fracture pressure determined from the test is used as the maximum pressure that may be imposed on that formation. Critical drilling decisions for mud weights, casing setting depths, and well control techniques are based upon the result of a LOT. …


Weierstrass Pairs And Minimum Distance Of Goppa Codes., Gretchen L. Matthews Jan 1999

Weierstrass Pairs And Minimum Distance Of Goppa Codes., Gretchen L. Matthews

LSU Historical Dissertations and Theses

We prove that elements of the Weierstrass gap set of a pair of points may be used to define a geometric Goppa code that has minimum distance greater than the usual lower bound. We determine the Weierstrass gap set of a pair of any two Weierstrass points on a Hermitian curve and use this to increase the lower bound on the minimum distance of certain codes defined using a linear combination of the two points. In particular, we obtain some two-point codes on a Hermitian curve that have better parameters than the one-point code on this curve with the same …
