Instance-Based Parameter Tuning Via Search Trajectory Similarity Clustering, Linda Lindawati, Hoong Chuin Lau, David Lo

Research Collection School Of Computing and Information Systems

This paper is concerned with automated tuning of parameters in local-search based meta-heuristics. Several generic approaches have been introduced in the literature that returns a ”one-size-fits-all” parameter configuration for all instances. This is unsatisfactory since different instances may require the algorithm to use very different parameter configurations in order to find good solutions. There have been approaches that perform instance-based automated tuning, but they are usually problem-specific. In this paper, we propose CluPaTra, a generic (problem-independent) approach to perform parameter tuning, based on CLUstering instances with similar PAtterns according to their search TRAjectories. We propose representing a search trajectory as …

Fine-Tuning Algorithm Parameters Using The Design Of Experiments Approach, Aldy Gunawan, Hoong Chuin Lau, Linda Lindawati

Research Collection School Of Computing and Information Systems

Optimizing parameter settings is an important task in algorithm design. Several automated parameter tuning procedures/configurators have been proposed in the literature, most of which work effectively when given a good initial range for the parameter values. In the Design of Experiments (DOE), a good initial range is known to lead to an optimum parameter setting. In this paper, we present a framework based on DOE to find a good initial range of parameter values for automated tuning. We use a factorial experiment design to first screen and rank all the parameters thereby allowing us to then focus on the parameter …

Different Strokes For Different Folks: A Different Standard Is Not Inherently A Double Standard, James E. Coleman Jr.

Faculty Scholarship

During the Senate’s closed confirmation hearings on President Dwight D. Eisenhower’s nomination of George E. Wilson, President of General Motors, to be Secretary of Defense, a senator asked Wilson if he would be able to make decisions as Secretary of Defense that were adverse to General Motors’ interest. Wilson replied that he would, but added he could not imagine having to make such a choice because “[f]or years I thought what was good for the country was good for General Motors and vice versa.” This bit of rhetorical bromide was reported erroneously by the press, which had been excluded from …

This review describes the biology, ecology, and epidemiology of known human pathogens in the family Anaplasmataceae that are transmitted by ticks and belong to the genus Anaplasma and genus Ehrlichia. We discuss the current status of diagnosis and surveillance of the diseases they cause, and address the challenges and new perspectives raised due to continuous recognition of new emerging human pathogens in the family Anaplasmataceae.

Archival Methods And The Veil Of Sociology, Mary Jo Deegan

Department of Sociology: Faculty Publications

Archival methods of research are crucial to reconstruct. interpret. and evaluate contributions of early sociologists that are hidden behind the veiIs of racism and sexism. Many of these founding sociologists profoundly shaped their communities and created important organizations to combat social inequality and injustice. Their lives as intellectuals were frequently controversial. which made them political anathemas to mainstream sociologists, usually white males working in prestigious universities who wanted money. fame, and prestige for the new discipline and its leaders.

In this chapter, [recount how r began a career using historical research to understand the rich. alternative history of the profession. …

Heterogeneity And Its Impact On Thermal Robustness And Attractor Density, Yuri Cantor, Bilal Khan, Kirk Dombrowski

Department of Sociology: Faculty Publications

There is considerable research relating the structure of Boolean networks to their state space dynamics. In this paper, we extend the standard model to include the effects of thermal noise, which has the potential to deflect the trajectory of a dynamical system within its state space, sending it from one stable attractor to another. We introduce a new “thermal robustness” measure, which quantifies a Boolean network’s resilience to such deflections. In particular, we investigate the impact of structural homogeneity on two dynamical properties: thermal robustness and attractor density. Through computational experiments on cyclic Boolean networks, we ascertain that as a …

The Impact Of A Wave Farm On Large Scale Sediment Transport, R Gonzalez Santamaria, Qp Zou, S Pan

School of Engineering, Computing and Mathematics

This study investigates the interactions of waves and tides at a wave farm in the southwest of England, in particular their effects on radiation stress, bottom stress, and consequently on the sediment transport and the coast adjacent to the wave-farm (the Wave Hub). In this study, an integrated complex numerical modelling system is setup at the Wave Hub site and is used to compute the wave and current fields by taking into account the wave-current interaction, as well as the sediment transport. Results show that tidal elevation and tidal currents have a significant effect on the wave height and direction …

Optimal And Heuristic Lead-Time Quotation For An Integrated Steel Mill With A Minimum Batch Size, Susan A. Slotnick

Business Faculty Publications

This paper presents a model of lead-time policies for a production system, such as an integrated steel mill, in which the bottleneck process requires a minimum batch size. An accurate understanding of internal lead-time quotations is necessary for making good customer delivery-date promises, which must take into account processing time, queueing time and time for arrival of the requisite volume of orders to complete the minimum batch size requirement. The problem is modeled as a stochastic dynamic program with a large state space. A computational study demonstrates that lead time for an arriving order should generally be a decreasing function …

Evaluation Of The Physicochemical Properties And Stability Of Solid Lipid Nanoparticles Designed For The Delivery Of Dexamethasone To Tumors, Melissa Howard

University of Kentucky Doctoral Dissertations

Pre-clinical and clinical trials suggest that pre-treatment with dexamethasone (Dex) may facilitate enhanced uptake of subsequently administered chemotherapeutic agents. To reduce the side effects associated with systemic administration of Dex, solid lipid nanoparticles (SLNs) containing dexamethasone palmitate (Dex-P) were prepared as a means of achieving tumor-targeted drug delivery. These studies were aimed at evaluating the physicochemical properties and both the physiological and storage stability of the SLNs.

SLNs were prepared using nanotemplate engineering technology. Stearyl alcohol (SA) was used as the lipid phase with Brij^® 78 and Polysorbate 60 as surfactants and PEG6000 monostearate as a long-chain PEGylating agent. …

Petrologic, Geochemical, And Geochronologic Constraints On The Tectonic Evolution Of The Southern Appalachian Orogen, Blue Ridge Province Of Western North Carolina, Eric Douglas Anderson

University of Kentucky Doctoral Dissertations

The Blue Ridge Province of western North Carolina contains a wide variety of metamorphosed igneous and sedimentary rocks that record the tectonic effects of Precambrian and Paleozoic orogenic cycles. Tectonic interpretations of the events that led to the present configuration are varied and often conflicting. This investigation examines metamorphosed mafic rocks that are widely interpreted to have formed during the closure of ocean basins. Metabasites, and specifically eclogites, have a tendency to mark tectonic sutures and frequently preserve pressure (P), temperature (T), and age data (t) that can be gleaned from mineral equilibria and U-Pb isotopic compositions. As such, the …

Advanced Studies On Series Impedance In Waveguides With An Emphasis On Source And Transfer Impedance, Jinghao Liu

University of Kentucky Doctoral Dissertations

Series impedances, including source and transfer impedances, are commonly used to model a variety of noise sources and noise treatment elements in duct systems. Particle velocity is assumed to be constant on the plane where the series impedances are defined. The research reported herein details investigations into measuring source and transfer impedance. Especially, the measurement and prediction of the transfer impedance of micro-perforated panel (MPP) absorbers is considered.

A wave decomposition method for measuring source impedance and source strength was developed that was purely based on acoustic concepts instead of the equivalent circuit analysis. The method developed is a two-load …

Resource Allocation And Efficient Routing In Wireless Networks, Jianjun Yang

University of Kentucky Doctoral Dissertations

In wireless networks, devices (nodes) are connected by wireless links. An important issue is to set up high quality (high bandwidth) and efficient routing paths when one node wants to send packets to other nodes. Resource allocation is the foundation to guarantee high quality connections. In addition, it is critical to handle void areas in order to set up detour-free paths. Moreover, fast message broadcasting is essential in mobile wireless networks. Thus, my research includes dynamic channel allocation in wireless mesh networks, geographic routing in Ad Hoc networks, and message broadcasting in vehicular networks.

The quality of connections in a …

Three Essays Evaluating Choices Of Teachers And Administrators In Kentucky Public Schools, Nathan Barrett

University of Kentucky Doctoral Dissertations

Public K-12 education is a large enterprise in the United States. Through local, state and federal sources, the U.S. allocated over $610 billion to K-12 public education in 2009 (NCES). Not only is the commitment of public funds for education substantial, the provision of K-12 education is primarily administered by the government in non-market settings through local school districts. It is this institutional environment that generates the impetus for evaluating how those in education make choices in the absence of markets.

Like traditional markets, non-market solutions often fail because the incentives facing individuals and agencies elicit choices which produce outcomes …
