The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes. Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.

Electronic Image Stabilization Using Optical Flow With Inertial Fusion, Michael J. Smith, Alexander J. Boxerbaum, Gilbert L. Peterson, Roger D. Quinn

Faculty Publications

When a camera is affixed on a dynamic mobile robot, image stabilization is the first step towards more complex analysis on the video feed. This paper presents a novel electronic image stabilization (EIS) algorithm for highly dynamic mobile robotic platforms. The algorithm combines optical flow motion parameter estimation with angular rate data provided by a strapdown inertial measurement unit (IMU). A discrete Kalman filter in feedforward configuration is used for optimal fusion of the two data sources. Performance evaluations are conducted using a simulated video truth model (capturing the effects of image translation, rotation, blurring, and moving objects), and live …

All Capstone Projects

The transformation of landscapes from rural to urban land use impacts affected ecosystems. Replacing natural vegetation with impervious surfaces and introducing environmental stressors through increased human activity can significantly alter aquatic ecosystems. This study examined the effects that urbanization had on salinity, dissolved oxygen, temperature, conductivity, and pH of aquatic systems along an urban-rural gradient in Illinois, Chicago land area- Little Calumet River, Thorn Creek, and Kankakee River. The first objective of this project was to examine whether there were changes or fluctuations among various environmental parameters that may be due to heavily populated residential areas when compared to a …

Synthesis And Analysis Of N-Acetyltyrosine-N-Ethyl Amide From N-Acetyl Yyrosine Ethyl Ester, Ravinder Reddy Akkuluri

All Capstone Projects

Amino acids gets oxidized when they are interacted with oxygen and light. And it is always difficult for the researchers to find and isolate a particular amino acid from a protein, unless they completely know how it behaves when interacted with light. For this we are synthesizing amide form of the amino acid which mimics the structure of a protein, and we induce light and find out the exact behavior of the particular amino acid. Here, the aim is to know the tyrosine interaction with light, so we synthesize amide form of tyrosine which is N-Acetyl tyrosine ethyl amide from …

Synthesis And Characterization Of An Europium-Porphyrin Complex, Alejandro Blinder

All Capstone Projects

Photodynamic therapy (PDT) is a promising treatment that has continued to improve over the past thirty years when the first commercially approved photosensitizer (PS) was introduced. Although PDT has many successful applications, the terrifying number of new cancer cases reported each year makes scientists focus their efforts towards the development of new efficient PS for PDT. The biggest obstacle that prohibits PDT from becoming a more widely used therapy is the ineffective photosensitizers (PS) that are available on the market today. The purpose of this study was to evaluate the synthesized metal-porphyrin complex as a possible candidate as a PS. …

Technical Target Setting In Qfd For Web Service Systems Using An Artificial Neural Network, Lianzhang Zhu, Xiaoqing Frank Liu

Computer Science Faculty Research & Creative Works

There are at least two challenges with quality management of service-oriented architecture based web service systems: 1) how to link its technical capabilities with customer's needs explicitly to satisfy customers' functional and nonfunctional requirements; and 2) how to determine targets of web service design attributes. Currently, the first issue is not addressed and the second one is dealt with subjectively. Quality Function Deployment (QFD), a quality management system, has found its success in improving quality of complex products although it has not been used for developing web service systems. In this paper, we analyze requirements for web services and their …

Suitability Review Of Common Synchronous, Live Online-Classroom Tools, Arnold Hensman

Conference Papers

While virtual learning environments (VLEs) such as Moodle and WebCT are now ubiquitous in most higher education institutes, live synchronous virtual classroom software is merely gaining in popularity. The first online meeting tools were tailored towards business requirements for remotely held meetings rather than educational purposes. The recent expansion of virtual classroom tools specific to education has changed this. Such software offers the standard features of streamed voice and video, yet purposely provides an array of additional features specifically designed to conduct classes online. While VLEs work optimally as a compliment to standard courses, Virtual-classrooms such as Adobe Connect Pro …

A Framework For The Comparison Of Virtual Classroom Systems, Daniel Mcsweeney

Conference Papers

The increase in demand for open and distance learning has resulted in many higher education providers investing in virtual classroom systems. These systems can be an essential component in the delivery of flexible and online courses. While many institutions correctly place a greater emphasis on the pedagogical development of flexible courses, poor selection or implementation of virtual classroom software can reduce the pedagogical effectiveness of such courses and in some cases render them unworkable for both lecturing staff and students.

Inductive Inference Of Languages From Samplings, Sanjay Jain, Efim Kinber

School of Computer Science & Engineering Faculty Publications

We introduce, discuss, and study a model for inductive inference from samplings, formalizing an idea of learning different “projections” of languages. One set of our results addresses the problem of finding a uniform learner for all samplings of a language from a certain set when learners for particular samplings are available. Another set of results deals with extending learnability from a large natural set of samplings to larger sets. A number of open problems is formulated.

Using Photoactive Vitamin Nanoparticles As Photodynamic Antimicrobial Chemotherapeutic (Pact) Agents To Treat Chronic Wounds, Rahul A. Khanke

All Capstone Projects

The objective of the proposed study is to develop new materials and methods to manage microbial growth in chronic wounds using phototherapy. Chronic wounds are considered as a worldwide health problem. The most common chronic wounds can be classified into three categories: venous ulcers, diabetic ulcers, and pressure ulcers. Venous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds and can become infected easily. Venous ulcers are sores that develop after veins in the legs have been damaged. These ulcers can penetrate deeply into the skin. Occasionally, if a venous ulcer persists for …

Program Transformations For Information Personalization, Saverio Perugini, Naren Ramakrishnan

Computer Science Faculty Publications

Personalization constitutes the mechanisms necessary to automatically customize information content, structure, and presentation to the end user to reduce information overload. Unlike traditional approaches to personalization, the central theme of our approach is to model a website as a program and conduct website transformation for personalization by program transformation (e.g., partial evaluation, program slicing). The goal of this paper is study personalization through a program transformation lens and develop a formal model, based on program transformations, for personalized interaction with hierarchical hypermedia. The specific research issues addressed involve identifying and developing program representations and transformations suitable for classes of hierarchical …

Three-Dimensional Reconnection And Relaxation Of Merging Spheromak Plasmas, Timothy G. Gray , '01, Vyacheslav S. Lukin , '00, Michael R. Brown, C. D. Cothran

Physics & Astronomy Faculty Works

Plasma relaxation inside a highly conducting cylindrical boundary is studied both experimentally and computationally. Dynamics are initiated by the introduction of two equal helicity spheromaks at either end of the cylinder. In the experiment, dense, high-magnetic-flux spheromaks are injected into the flux conserving volume with magnetized plasma guns. In the simulation, identical spheromaks initially occupy both halves of the cylinder and a perturbation is introduced. Merging commences with a single three-dimensional null-point that moves radially out of the flux conserving volume at velocities up to 0.2 of the reconnection outflow velocity. Relaxation to the minimum energy state occurs in about …

Labeling Of Fluorescein Dye On Folate Binding Protein, Sravanth Reddy Lakshmareddygari

All Capstone Projects

Discovery and development of folic acid based receptor targeting started in late 1991 and early 1992 when researchers came to know that folate receptors (FR) are over expressed on malignant tissues. The malignant tissues over express special folate receptors to capture more folate from the blood stream as folate is required for cell division. The researchers found that folate can be used as an optimal targeting ligand that would bind selectively to pathologic cells, displaying no affinity for healthy cells. Then they focused on attaching a drug molecule to the folate ligand that can be delivered directly to the cells …

Labeling Of Folic Acid On Bovine Serum Albumin, Hari Krishna Kosuri

All Capstone Projects

Recent Clinical research focused mainly on the therapeutic safety which mainly involves the avoidance of toxicities. To prevent the toxicities, site targeted drugs are improved which exhibit their therapeutic action on the specific target or the diseased target without disturbing the healthy cells. Folic acid, a natural Vitamin (Vit B9) has shown promising results in site specificity mainly in the cancer cells where they are abundantly present.

Folic acid is of great importance because of the promising results of several clinical trials which demonstrate that Folic acid increases the potency and simultaneously reducing the toxicity of the cancer therapies. Various …

Total Protein Determination Using Micro Plate Assay, Julie Ruffatti

All Capstone Projects

One of the largest challenges that food manufactures are facing today is the management of food allergens. Allergenic protein in trace amounts, part per million concentrations, will trigger a reaction in some individuals. Food manufacturers need to prevent allergen cross-contamination by performing adequate sanitation after production of an allergenic containing food. Allergen detection kits are used to determine if sufficient protein was removed from the equipment surfaces during sanitation. One kit on the market is the 3M™ Clean- Trace™ Surface Protein (Allergen) swab tests. The test qualitatively detects the presence of protein based on the biuret reaction and will yield …

Purification And Analysis Of Folate-Dye Conjugate, Dilipkumar Sakhiya

All Capstone Projects

The folate receptor has achieved great importance for use in targeted drug delivery and in vitro and in vivo diagnostic assays. The folate receptor (FR) is over-expressed on several cancer cell types and activated macrophages, but exists in relatively low abundance on the surface of non-cancerous tissue and non inflammatory cells. This unique attribute is the hallmark of folate-targeted methodologies allowing the diagnostic agent and/or drug to be ferried to the specific disease sites while preventing “off target” effects in normal tissues. Protein toxins, chemotherapeutic agents, radioimaging agents, magnetic resonance imaging (MRI) contrast agents liposomes with entrapped drugs, radiotherapeutic agents, …

Cox-2 Inhibitor Nimesulide Analogs Are Aromatase Suppressors In Breast Cancer Cells, Bin Su, Xiaohan Cai, Yanyan Hong, Shiuan Chen

Chemistry Faculty Publications

Cyclooxygenase-2 (COX-2) inhibitor nimesulide derivatives compounds A and B decreased aromatase activity in breast cancer cells via a novel mechanism different to aromatase inhibitors (AIs), and were defined as “aromatase suppressors”. Breast carcinoma cells (MCF-7aro and T47Daro) transfected with aromatase full gene were used to explore the mechanisms of the two compounds. They dose and time-dependently suppressed aromatase activity in MCF-7aro and T47Daro cells in the nanomole range. However, they neither directly inhibited aromatase, nor improved aromatase degradation even at much higher concentrations. They could also suppress androgen stimulated cell growth, but did not affect estrogen enhanced cell proliferation. These …

Measurement And Modeling Of Infrared Nonlinear Absorption Coefficients And Laser-Induced Damage Thresholds In Ge And Gasb, Torrey J. Wagner, Matthew J. Bohn, Ronald A. Coutu Jr., L. P. Gonzales, J. M. Murray, K. L. Schepler, S. Guha

Faculty Publications

Using a simultaneous fitting technique to extract nonlinear absorption coefficients from data at two pulse widths, we measure two-photon and free-carrier absorption coefficients for Ge and GaSb at 2.05 and 2.5 µm for the first time, to our knowledge. Results agreed well with published theory. Single-shot damage thresholds were also measured at 2.5 µm and agreed well with modeled thresholds using experimentally determined parameters including nonlinear absorption coefficients and temperature dependent linear absorption. The damage threshold for a single-layer Al₂O₃ anti-reflective coating on Ge was 55% or 35% lower than the uncoated threshold for picosecond or nanosecond …
