Optimum Non Hydrocarbon Gas Injection Development Process And Ultimate Recovery Maximization., Abdulla A.F. Abed

Theses

A multi layered heterogeneous reservoir was selected for this study. The integrated reservoir characterization model and the pertinent transformed reservoir simulation history matched model were quality assured and quality checked.

The development scheme was identified and selected where the pattern and completion of the wells were defined to fit the heterogeneity of the reservoir characterization model. Lateral and maximum block contact holes were investigated.

The development processes studied were mainly hydrogen sulphide, carbon dioxide, nitrogen and rich hydrocarbon gas. The Water Alternating Gas/ Simultaneous Water Alternating Gas (WAG/SWAG) processes were also assured. In addition to the main gas and WAG/SWAG …

A Neural Network Model For A Hierarchical Spatio-Temporal Memory, Kiruthika Ramanathan, Luping Shi, Jianming Li, Kian Guan Lim, Zhi Ping Ang, Chong Chong Tow

Research Collection School Of Computing and Information Systems

The architecture of the human cortex is uniform and hierarchical in nature. In this paper, we build upon works on hierarchical classification systems that model the cortex to develop a neural network representation for a hierarchical spatio-temporal memory (HST-M) system. The system implements spatial and temporal processing using neural network architectures. We have tested the algorithms developed against both the MLP and the Hierarchical Temporal Memory algorithms. Our results show definite improvement over MLP and are comparable to the performance of HTM.

A New Framework For The Design And Analysis Of Identity-Based Identification Schemes, Guomin Yang, Jing Chen, Duncan S. Wong, Xiaotie Deng, Dongsheng Wang

Research Collection School Of Computing and Information Systems

Constructing an identification scheme is one of the fundamental problems in cryptography, and is very useful in practice. An identity-based identification (IBI) scheme allows a prover to identify himself to a public verifier who knows only the claimed identity of the prover and some public information. In this paper, we propose a new framework for both the design and analysis of IBI schemes. Our approach works in an engineering way. We first identify an IBI scheme as the composition of two building blocks, and then show that, with different security properties of these building blocks, the corresponding IBI schemes can …

Two-Factor Mutual Authentication Based On Smart Cards And Passwords, Guomin Yang, Duncan S. Wong, Huaxiong Wang, Xiaotie Deng

Research Collection School Of Computing and Information Systems

One of the most commonly used two-factor user authentication mechanisms nowadays is based on smart-card and password. A scheme of this type is called a smart-card-based password authentication scheme. The core feature of such a scheme is to enforce two-factor authentication in the sense that the client must have the smart-card and know the password in order to gain access to the server. In this paper, we scrutinize the security requirements of this kind of schemes, and propose a new scheme and a generic construction framework for smart-card-based password authentication. We show that a secure password based key exchange protocol …

Profile-Guided Program Simplification For Effective Testing And Analysis, Lingxiao Jiang, Zhendong Su

Research Collection School Of Computing and Information Systems

Many testing and analysis techniques have been developed for inhouse use. Although they are effective at discovering defects before a program is deployed, these techniques are often limited due to the complexity of real-world code and thus miss program faults. It will be the users of the program who eventually experience failures caused by the undetected faults. To take advantage of the large number of program runs carried by the users, recent work has proposed techniques to collect execution profiles from the users for developers to perform post-deployment failure analysis. However, in order to protect users' privacy and to reduce …

Bias And Controversy In Evaluation Systems, Hady Wirawan Lauw, Ee Peng Lim, Ke Wang

Research Collection School Of Computing and Information Systems

Evaluation is prevalent in real life. With the advent of Web 2.0, online evaluation has become an important feature in many applications that involve information (e.g., video, photo, and audio) sharing and social networking (e.g., blogging). In these evaluation settings, a set of reviewers assign scores to a set of objects. As part of the evaluation analysis, we want to obtain fair reviews for all the given objects. However, the reality is that reviewers may deviate in their scores assigned to the same object, due to the potential bias of reviewers or controversy of objects. The statistical approach of averaging …

Model-Driven Remote Attestation: Attesting Remote System From Behavioral Aspect, Liang Gu, Xuhua Ding, Robert H. Deng, Yanzhen Zou, Bing Xie, Weizhong Shao, Hong Mei

Research Collection School Of Computing and Information Systems

Remote attestation was introduced in TCG specifications to determine whether a remote system is trusted to behave in a particular manner for a specific purpose; however, most of the existing approaches attest only the integrity state of a remote system and hence have a long way to go in achieving the above attestation objective. Behavior-based attestation and semantic attestation were recently introduced as solutions to approach the TCG attestation objective. In this paper, we extend behavior-based attestation to a model-driven remote attestation to prove that a remote system is trusted as defined by TCG. Our model-driven remote attestation verifies two …

Real Exchange Rate And International Reserves In An Era Of Growing Financial And Trade Integration, Joshua Aizenman, Daniel Riera-Crichton

All Faculty Scholarship

This paper evaluates the impact of international reserves, terms-of-trade shocks, and capital flows on the real exchange rate (REER). We observe that international reserves cushion the impact of terms-oftrade shocks on REER, and that this effect is important for developing but not for industrial countries. This buffer effect is especially significant for Asian countries, and for countries exporting natural resources. Financial depth reduces the buffer role of international reserves in developing countries. Developing countries' REERs seem to be more sensitive to changes in reserve assets; whereas industrial countries display a significant relationship between hot money and REER. © 2008 by …

An Ounce Of Prevention: Solving Some Unforeseen Problems With The Proposed Amendments To Rule 56 And The Federal Summary Judgment Process, Adam N. Steinman

Faculty Scholarship

The Civil Rules Advisory Committee has recently proposed the most significant revisions to Rule 56 since the Federal Rules of Civil Procedure were adopted seventy years ago. Although the stated goal of the proposed amendments is laudable - "to improve the procedures for making and opposing summary-judgment motions, and to facilitate the judge's work in resolving them" - this Essay in the Northwestern University Law Review Colloquy identifies some unanticipated problems with the proposed text. Contrary to the Advisory Committee's intent, the proposed text may inadvertently make substantial changes to the summary-judgment standard and the burdens on litigants at the …

Search For Gravitational-Wave Bursts From Soft Gamma Repeaters, B. P. Abbott, R. Abbott, Mario C. Diaz, R. Grosso, K. Hayama, Soma Mukherjee, Soumya Mohanty, Joseph D. Romano, Robert Stone

Physics & Astronomy Faculty Publications

We present a LIGO search for short-duration gravitational waves (GWs) associated with soft gamma ray repeater (SGR) bursts. This is the first search sensitive to neutron star f modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from SGR 1806−20 and 190 lesser events from SGR 1806−20 and SGR 1900+14. The unprecedented sensitivity of the detectors allows us to set the most stringent limits on transient GW amplitudes published to date. We find upper limit estimates on the …

Mosfet Modulated Dual Conversion Gain Cmos Image Sensors, Xiangli Li

Boise State University Theses and Dissertations

In recent years, vision systems based on CMOS image sensors have acquired significant ground over those based on charge-coupled devices (CCD). The main advantages of CMOS image sensors are their high level of integration, random accessibility, and low-voltage, low-power operation. Previously proposed high dynamic range enhancement schemes focused mainly on extending the sensor dynamic range at the high illumination end. Sensor dynamic range extension at the low illumination end has not been addressed. Since most applications require low-noise, high-sensitivity, characteristics for imaging of the dark region as well as dynamic range expansion to the bright region, the availability of a …

Genetic Change Following Fire In Populations Of A Seed-Banking Perennial Plant, Rebecca W. Dolan, Pedro F. Quintana-Ascencio, Eric S. Menges

Scholarship and Professional Work - LAS

Disturbances such as fire have the potential to remove genetic variation, but seed banks may counter this loss by restoring alleles through a reservoir effect. We used allozyme analysis to characterize genetic change in two populations of the perennial Hypericum cumulicola, an endemic of the fire-prone Florida scrub. We assessed genetic variation before and 1, 2, and 3 years after fire that killed nearly all aboveground plants. Populations increased in size following fire, with most seedlings likely recruited from a persistent seed bank. Four of five loci were variable. Most alleles were present in low frequencies, but our large sample …

A Competitive Hybridization Model Predicts Probe Signal Intensity On High Density Dna Microarrays, Shuzhao Li, Alex Pozhitkov, Marius Brouwer

Faculty Publications

A central, unresolved problem of DNA microarray technology is the interpretation of different signal intensities from multiple probes targeting the same transcript. We propose a competitive hybridization model for DNA microarray hybridization. Our model uses a probe-specific dissociation constant that is computed with current nearest neighbor model and existing parameters, and only four global parameters that are fitted to Affymetrix Latin Square data. This model can successfully predict signal intensities of individual probes, therefore makes it possible to quantify the absolute concentration of targets. Our results offer critical insights into the design and data interpretation of DNA microarrays.

Cardiorespiratory Fitness As A Predictor Of Fatal And Nonfatal Stroke In Asymptomatic Women And Men, Steven P. Hooker, Xuemei Sui, Natalie Colabianchi, John E. Vena, James N. Laditka, Michael J. Lamonte, Steven N. Blair

Faculty Publications

Background and Purpose - Prospective data on the association between cardiorespiratory fitness (CRF) and stroke are largely limited to studies in men or do not separately examine risks for fatal and nonfatal stroke. This study examined the association between CRF and fatal and nonfatal stroke in a large cohort of asymptomatic women and men.

Methods - A total of 46,405 men and 15,282 women without known myocardial infarction or stroke at baseline completed a maximal treadmill exercise test between 1970 and 2001. CRF was grouped as quartiles of the sex-specific distribution of maximal metabolic equivalents achieved. Mortality follow-up was through …

Polymer Supported Optical Biosensors, Ignacio Joseph Garcia

Electronic Theses and Dissertations

The use of various polymer supports adhering phospholipid multibilayers to an internal reflection element have been investigated. The polymer supports studied range from polystyrene (PS), and 100 nm wide PS nanospheres to triethylaminated poly(vinyl benzyl chloride) (PVBC). The PS nanospheres showed the most promise as an adhesion layer since they appear to be the most robust with repeated washings. They also appear to stabilize their adjacent phospholipid multibilayer by increasing the lipid melting temperature. The triethylaminated DVBC also provided an increase of lipid melting temperature, but not quite to the same degree as the PS nanospheres. The cooperativity of such …

With the advent of the No Child Left Behind (NCLB) legislation, many changes are occurring in the field of special education. More than ever before, students with disabilities are being included in each state’s NCLB required assessment to determine adequate yearly progress. This has resulted in an influx of students with disabilities enrolled in intensive reading classes in the schools. Educators, administrators, and reading coaches are attempting to figure out the best way to educate these students to achieve the reading gains that NCLB requires. The purpose of this study was to examine factors believed to affect reading achievement of …

A Case Study: The Preparedness Of Adult Education Students For College-Level Education, Julie Gibbons Griffin

Doctoral Dissertations and Projects

Each year adult education programs have served over three million people. Approximately 40% of these students aged 24 years and younger who were economically and educationally disadvantaged have benefited from postsecondary education. Although adult education programs have offered high school diploma (HSD) and General Educational Development (GED) credentials to the adult population including young adults, many of the graduates who enrolled in higher education failed to enter at college-level. Because most non-traditional students left college during their first year, their preparation for college-level education had a dire consequence for not only their success, but that of society as well. The …

With 60 participants in the study, the students were equally divided into two groups of 30 participants each. Group I was designated as the treatment group, while Group II formed the control group. A two-tailed t-test was used to determine that the means of the two posttests were not significantly different at a probability level of .05. Therefore, the results of this research study indicated that high …

The Value Of Intraoperative Examination Of Axillary Sentinel Nodes In Carcinoma Of The Breast., Gordon F. Schwartz, Lauren S. Krill, Juan P. Palazzo, Abhijit Dasgupta

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Abstract Axillary sentinel lymph node biopsy (SLNB) has become the standard of care for T1-2, N-0, M-0 carcinoma of the breast. However, the accuracy of frozen section in the intra-operative examination of sentinel nodes (SN) remains controversial. The senior author has championed the use of the intraoperative examination of SN by frozen section ex-amination from the inception of its use, and we present our experience with frozen section examination of SN, confirming that this technique is both practical and highly accurate. Materials & Methods: Between 2000 and 2007, 236 SLNB procedures were performed that were read as “fro-zen section negative.” …

A Method To Quantify Residents' Jargon Use During Counseling Of Standardized Patients About Cancer Screening, Lindsay Deuster, Stephanie Christopher, Jodi Donovan, Michael Farrell

College of Professional Studies Faculty Research and Publications

Background

Jargon is a barrier to effective patient-physician communication, especially when health literacy is low or the topic is complicated. Jargon is addressed by medical schools and residency programs, but reducing jargon usage by the many physicians already in practice may require the population-scale methods used in Quality Improvement.

Objective

To assess the amount of jargon used and explained during discussions about prostate or breast cancer screening. Effective communication is recommended before screening for prostate or breast cancer because of the large number of false-positive results and the possible complications from evaluation or treatment.

Participants

Analyzing The Catalytic Mechanism Of The Fe-Type Nitrile Hydratase From Comamonas Testosteroni Ni1, Saroja Rao, Richard C. Holz

Chemistry Faculty Research and Publications

In order to gain insight into the catalytic mechanism of Fe-type nitrile hydratases (NHase), the pH and temperature dependence of the kinetic parameters k_cat, K_m, and k_cat/K_m along with the solvent isotope effect were examined for the Fe-type NHase from Comamonas testosteroni Ni1 (CtNHase). CtNHase was found to exhibit a bell-shaped curve for plots of relative activity vs pH over pH values 4−10 for the hydration of acrylonitrile and was found to display maximal activity at pH ∼7.2. Fits of these data provided a pK_ES1 value of …
