A Particle Swarm Optimization Using Random Keys For Flexible Flow Shop Scheduling Problem With Sequence Dependent Setup Times, Vinodh Sankaran

All Theses

In this research, a particle swarm optimization algorithm (PSO) using random keys is developed to schedule flexible flow lines with sequence dependent setup times to minimize makespan. The flexible flow line scheduling problem is a branch of production scheduling and is found in industries such as printed circuit board and automobile manufacturing. It is well known that this problem is NP-hard. For this reason, we approach the problem by implementing a particle swarm optimization (PSO), a metaheuristic which is inspired by the motion of a flock of birds or a school of fish searching for food. The proposed PSO has …

The 'I' In Team: Effects Of Performance Appraisal Type On Teamwork Variables, Brandy Brown

All Theses

The following research examined the effects of performance appraisal condition on teamwork variables. As more reliable models of teamwork emerge, there remains a noticeable lack of information regarding team motivation and feedback in an organizational context. This paper first reviews the current findings on team motivation, feedback, and performance appraisals and then applies that topic to teamwork processes. The researcher proposed that individual, team, and dual (individual and team feedback) performance appraisals would have different effects on teamwork processes and performance. Positive effects on team orientation, mutual trust, and team performance in the team and dual performance appraisal conditions were …

Modeling The Cooling Phase Of The Lens Molding Process, Saravanan Kannan

All Theses

The lens molding process is a relatively new technique used to manufacture lenses, in particular, high precision aspheric lenses. In order to achieve the desired size and shape of the lens, the cooling process after pressing must be controlled precisely because of the time and temperature dependent viscoelastic behavior of glass near and below the molding temperature. This thesis gives a detailed description of a three-dimensional computational model for analyzing the cooling phase of the lens molding process. Conduction, convection and radiation are considered in the model by coupling a computational fluid dynamics analysis of the flow of nitrogen through …

Interactive Perception For Cluttered Environments, Robert Willimon

All Theses

Robotics research tends to focus upon either non-contact sensing or machine manipulation, but not both. This paper explores the benefits of combining the two by addressing the problem of extracting and classifying unknown objects within a cluttered environment, such as found in recycling and service robot applications. In the proposed approach, a pile of objects lies on a flat background, and the goal of the robot is to sift through the pile and classify each object so that it can be studied further. One object should be removed at a time with minimal disturbance to the other objects. We propose …

A Logistic Regression Model To Predict Incident Severity Using The Human Factors Analysis And Classification System, Hrishikesh Kavade

All Theses

The Human Factors Analysis and Classification System (HFACS) is used to help identify causal factors that lead to human error. The framework has been used in a variety of industries to identify leading contributing factors of unsafe events, such as accidents, incidents and near misses. While traditional application of the HFACS framework to safety outcomes has allowed evaluators to identify leading causal issues based on frequency, little has been done to gain a more comprehensive view of the system's total risk. This work utilizes the concept of event severity along with the HFACS framework to help better identify target areas …

Considering positive potentials of PHEVs and VII in ITS, a framework that integrates PHEVs with VII technology was created in this research utilizing vehicle-to-vehicle and vehicle-to-infrastructure communications for …

Cyber Attacks: Does Physical Boundary Matter?, Qiu-Hong Wang, Seung-Hyun Kim

Research Collection School Of Computing and Information Systems

Information security issues are characterized with interdependence. Particularly, cyber criminals can easily cross national boundaries and exploit jurisdictional limitations between countries. Thus, whether cyber attacks are spatially autocorrelated is a strategic issue for government authorities and a tactic issue for insurance companies. Through an empirical study of cyber attacks across 62 countries during the period 2003-2007, we find little evidence on the spatial autocorrelation of cyber attacks at any week. However, after considering economic opportunity, IT infrastructure, international collaboration in enforcement and conventional crimes, we find strong evidence that cyber attacks were indeed spatially autocorrelated as they moved over time. …

The Cryogenic Bonding Evaluation At The Metallic-Composite Interface Of A Composite Overwrapped Pressure Vessel With Additional Impact Investigation, Eric A. Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A bonding evaluation that investigated the cryogenic tensile strength of several different adhesives / resins was performed. The test materials consisted of 6061 aluminum test pieces adhered to a wet-wound graphite laminate in order to simulate the bond created at the liner-composite interface of an aluminum lined composite overwrapped pressure vessel. It was found that for cryogenic applications, a flexible, low modulus resin system must be used. Additionally, the samples prepared with a thin layer of cured resin – or prebond – performed significantly better than those without. It was found that it is critical that the prebond surface must …

Optimal Experience In Relationships, Activities, And Beyond: Connecting Flow With Self-Expansion, Brandy M. Dean

All-Inclusive List of Electronic Theses and Dissertations

Flow is a state of optimal experience characterized by complete immersion in an enjoyable activity and has been associated with positive experience in activities. Self-expansion is a state of increase in the diversity and complexity of the self and has been linked with positive experience in relationships. Despite phenomenological similarities, the connection between these two states has not been examined. The current study used a correlational design to explore the degrees of overlap between these states by comparing them in general, situation-specific, and predictive contexts. It was expected that flow and self-expansion would occur at similar frequencies, be produced by …

Working Memory, Cues, And Wayfinding In Older Women, Rebecca L. Davis, Barbara A. Therrien, Brady T. West

Peer Reviewed Articles

Individuals create cognitive maps based on relationships between cues in the environment. Older individuals are often impaired in wayfinding, especially in environments that lack distinctive features. This study examines how working memory ability in older women is related to wayfinding performance in the presence of salient (distinctive, prominent) or nonsalient cues. The degree of salient cue complexity is also examined, thus leading to the hypothesis that salient, complex cues are important in wayfinding and that working memory capacity is related to wayfinding performance. The virtual computer-generated arena is used to test this hypothesis in 20 healthy older women in three …

Economics Of The Super Bowl, Victor Matheson

Economics Department Working Papers

The Super Bowl is America’s premier sporting event. This paper details basic economic facts about the game as examines the controversy surrounding the purported economic impact of the game on host communities. While the league and sports boosters claim that the game brings up to a $500 million economic impact to host cities, a review of the literature suggests that the true economic impact is a fraction of this amount.

A Contrast Pattern Based Clustering Quality Index For Categorical Data, Qingbao Liu, Guozhu Dong

Kno.e.sis Publications

Since clustering is unsupervised and highly explorative, clustering validation (i.e. assessing the quality of clustering solutions) has been an important and long standing research problem. Existing validity measures have significant shortcomings. This paper proposes a novel contrast pattern based clustering quality index (CPCQ) for categorical data, by utilizing the quality and diversity of the contrast patterns (CPs) which contrast the clusters in clusterings. High quality CPs can characterize clusters and discriminate them against each other. Experiments show that the CPCQ index (1) can recognize that expert-determined classes are the best clusters for many datasets from the UCI repository; (2) does …

Patent Expertise And The Regress Of Useful Arts, Andrew W. Torrance, Bill Tomlinson

Southern Illinois University Law Journal

Recent studies and findings have unveiled that patent systems may not accomplish the goal of technological progress as well as a commons system, at least in terms of innovation, productivity, and social utility.  Employing The Patent Game, a multi-user interactive simulation of patent and non-patent (commons and open source) systems, the authors of this Article are currently comparing rates of innovation, productivity, and social utility, but with expert users possessing formal expertise in patent law and open innovation.

This Article presents results of this study, which indicates no statistically significant difference in rates of innovation among a pure patent system, …

In Re Marriage Of Matchen, 866 N.E.2d 683 (Ill. App. Ct. 2007): Illinois Removal Standards Do Not Match Up With The Current National Trend, Misty Edwards

Southern Illinois University Law Journal

The Illinois Marriage and Dissolution of Marriage Act provides that a parent who wishes to move out of the state of Illinois with a child must first petition the court for permission.  The court then bases its decision whether the child may be removed on the "best interests of the child" standard.  This Casenote examines the difficulty of applying the "best interests of the child" standard and advocates that Illinois adopt a standard favoring the present national trend: the ability of a custodial parent to move out of state unless motivated by bad faith.

High Contrast Grayscale Object Tracking Embedded System Design, Scott Donald Neally

Electrical Engineering

The purpose of this project is to prove that a real-time object-tracking camera can be implemented using the Digilent NEXYS board with Xilinx Platform Studio. With great ambition I set to implement the camera with RGB color tracking of bright green objects. This would make segmentation between the object of interest and its background much easier, allowing less stringent requirements on the background color beyond the object. Because of time restraints, the actual implementation remains as 8-bit grayscale, where the object of interest is intended to be white and highly contrasted from its black background. A simple algorithm is used …

Parental Perceptions Of Body Mass Index Referrals And Overweight School-Age Children, Misty Schwartz

Department of Educational Administration: Dissertations, Theses, and Student Research

It is well documented that there is a worldwide epidemic of obesity in children. To address obesity in children, emphasis must be on factors within family, school, and community environments. Although most parents and school officials are aware of the problem of overweight children, there is little data available to guide decision making about the acceptability of school-based Body Mass Index (BMI) screening and referral programs. As states mandate BMI screening and referral, parental insight is essential to determine the efficiency and effectiveness of BMI notification.

The purpose of this multiple case study was to explore the perceptions of parents …

Developmental Asset Building In At-Risk Youth: A Mixed Methods Study, Kraig James Lofquist

Department of Educational Administration: Dissertations, Theses, and Student Research

The purpose of this mixed methods triangulation design study was to explore how “service learning” affects “at-risk” student’s overall level of Developmental Assets. Quantitative data were obtained by using a pre and post assessment. Specifically, the Developmental Asset Profile (DAP) was used to determine if “service learning” opportunities increased the overall levels of developmental assets experienced by the atrisk student group. Additionally, qualitative data were gained by interviewing service learning participants to supplement the quantitative data collected in the Developmental Asset Profile.

Participants included 37 “at-risk” youth who were selected to participate in a service learning program. The students selected …

Punching Bag Trainer, Gian Delacruz

Electrical Engineering

Martial artists, such as boxers, kick boxers, and karate practitioners, use punching bags in training all the time to work on technique, speed and power but there hasn’t really been a good way to train reaction and combination speed (a combination is a string of strikes) without the aid of a training partner. Reaction and combination speed are important in competition because a faster competitor can attack successfully before his or her opponent has the time to react. This device aims to help martial artists increase reaction and combination speed through the use of randomly flashing targets attached to a …

Protected Ir Input System, Kevin Ersoy

Electrical Engineering

The result of this project is a product that may be used to apply a digital input to a system without physically touching a device. The combination of a modulated IR signal and reflective technology produces this remote actuation. The signal emitter should produce the modulated IR light, and the receiver should continuously wait for this signal to be received. If the IR signal should encounter an obstruction causing reflection at the appropriate distance, it will be reflected directly into the receiving device. This project may be extended to include multiple duplicate systems in proximity by transmitting a modulated digital …

Has The Marital Time Cost Of Parenting Changed Over Time?, Jeffrey P. Dew

Faculty Publications

Qualitative and quantitative research has suggested that married couples handle the increasing demands of intensive parenting norms and work expectations by reducing spousal time (e.g., the time that spouses spend alone with each other). Using nationally representative time-diary data, this study examined whether married individuals with children at home lost more spousal time in the years 1975–2003 than individuals without children at home. The analyses showed that on average married individuals have reduced their spousal time by 50 minutes a day. Contrary to expectations, however, individuals with minor children at home had lower time declines than individuals without children. The …

New Infrared Spectral Data For 27 Asteroids: An Investigation Of Meteorite-Asteroid Relationships By Using The Modified Gaussian Model, Katherine Marie Gietzen

Graduate Theses and Dissertations

Asteroids provide unique insights into the origin and early history of the solar system. Since asteroids are considered to be fairly pristine, studying them provides opportunities to learn more about the primordial solar system, its materials, processes and history. Since the discovery in 1801 of the first asteroid, Ceres, during the era when everyone was searching for the "missing planet", astronomers have been trying to understand what they are, where they came from, why they exist and what they can tell us about how our solar system formed and evolved.

Within the asteroid population are a number of sub-populations, the …

Publications (E)

The study presented in this report examines issues concerning whether achieving net-zero energy performance at the community scale provides economic and potentially overall efficiency advantages over strategies focused on individual buildings.

Trade-Offs Between Predation Risk And Forage Differ Between Migrant Strategies In A Migratory Ungulate, Mark Hebblewhite, Evelyn Merrill

Wildlife Biology Faculty Publications

Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an "escape'' from predation, but trade-offs can also occur at finer spatial scales. Previous authors suggest that ungulates will avoid predation risk at the largest scale, although few studies have examined multi-scale trade-offs to test for the relative benefits of risk avoidance across scales. Building on previously developed spatial models of forage and wolf predation risk, we tested for trade-offs at the broad landscape scale and at a finer, within-home-range scale for migratory and …

An Economic Development Paradox: The Impact Of Linkages And Synergies Among Local Agents In The Development Of An Emergent Bioscience Cluster And Associated Entrepreneurial Ecosystems, Francisco Montalvo

Student Scholarship

Although bioscience industrial clusters have been widely researched in the last decade, the role of knowledge creation, management, and transfer as driving forces for industrial cluster competitiveness remains unclear. A better appreciation of knowledge creation and retention as determinants of industrial cluster success, and the role of foreign direct investment may be of value to industry decision makers, policy makers, and researchers worldwide. Our research revealed a paradox regarding the intensity of foreign direct investment (FDI) by multinational companies (MNCs) and the limited development of a local entrepreneurial ecosystem in an emergent bioscience cluster. While cluster development seems a logical …

Using Labeled Data To Evaluate Change Detectors In A Multivariate Streaming Environment, Albert Y. Kim, Caren Marzban, Donald B. Percival, Werner Stuetzle

Statistical and Data Sciences: Faculty Publications

We consider the problem of detecting changes in a multivariate data stream. A change detector is defined by a detection algorithm and an alarm threshold. A detection algorithm maps the stream of input vectors into a univariate detection stream. The detector signals a change when the detection stream exceeds the chosen alarm threshold. We consider two aspects of the problem: (1) setting the alarm threshold and (2) measuring/comparing the performance of detection algorithms. We assume we are given a segment of the stream where changes of interest are marked. We present evidence that, without such marked training data, it might …

Manifesting Love: Developing A Bible Camp Week For Gay Young Adults, Scott A. Luikart

Creativity and Change Leadership Graduate Student Master's Projects

This project serves to create an inclusive camp community to teach young gay adults about love and give them a sense of belonging in a religious setting. This sense will be manifested as the participants discuss four forms of love and create a personal manifesto.
