The Design And Testing Of A Solar Autoclave With Broad Spectrum Sterilization Capabilities, Sarah S. Trabia

Honors College Theses

Energy is difficult to come by in developing countries and this interferes with the ability of doctors to provide good healthcare to their patients. Without decent sterilization, patients can become infected and diseases can spread throughout hospitals. This study involves designing a solar autoclave for developing countries that is as efficient as electrical autoclaves. The design is intended to not require any electrical input and to be affordable to those who cannot afford advanced medical equipment. Once the solar autoclave is designed, it will be tested to determine if it can sterilize equipment against a variety of different bacteria, including …

Students’ Views Of Impact Of Textbooks On Their Achievements, Riaz Hussain

Institute for Educational Development, Karachi

The history of curricula and textbooks development in Pakistan has remained contentious particularly during Zia Ul Haq era (1977- 1988) and after. There have been quite a few reviews of the curricula and textbooks undertaken both by Ministry of Education, Government of Pakistan and independent researchers. These reviews have mainly employed document/textbook analysis methods and few of them explored teachers or students’ views of curricula and textbooks. This paper argues that since teachers and students are the ultimate users and beneficiaries of textbooks so their views are worth exploring before suggesting or initiating any change process including curricula and textbooks …

Comparing Two Independent Groups Via A Quantile Generalization Of The Wilcoxon-Mann-Whitney Test, Rand R. Wilcox

Journal of Modern Applied Statistical Methods

The Wilcoxon-Mann-Whitney test, as well as modern improvements, are based in part on an estimate of p = P(D < 0), where D = X−Y and X and Y are independent random variables; a common goal is to test H₀: p = 0.5. This corresponds to testing H₀: ξ_0.5, where ξ_0.5 is the 0.5 quantile of the distribution of D. If the distributions associated with X and Y do not differ, then D has a symmetric distribution about zero. In particular, ξ_q + ξ_1-q = 0 for any q ≤ 0.5, where ξ_q is the q^th quantile. Methods aimed at testing H₀: p = 0.5 are generalized by …

Single Sampling Plans For Variables Indexed By Aql And Aoql With Measurement Error, R. Sankle, J.R. Singh

Journal of Modern Applied Statistical Methods

Single sampling plans are investigated for variables indexed by acceptable quality level (AQL) and average outgoing quality limit (AOQL) under measurement error. Procedures and tables are provided for selection of single sampling plans for variables for given AQL and AOQL when rejected lots are 100% inspected for replacement of a nonconforming unit. For a particular sampling plan in operation for an observed measurement, a method for determining true operating characteristic (OC) functions and average outgoing quality (AOQ) is described for various error sizes.

An Extension Of Cochran-Orcutt Procedure For Generalized Linear Regression Models With Periodically Correlated Errors, Abdullah A. Smadi, Nour H. Abu-Afouna

Journal of Modern Applied Statistical Methods

An important assumption of ordinary regression models is independence among errors. This research considers the case of periodically correlated errors following the periodic AR model of order 1 (PAR(1)). The remedial measure for correlated errors in regression known as the Cochran-Orcutt procedure is generalized to the case of periodically correlated errors. The motivation for making such generalizations is that the response data may inhibit some seasonality, which may not be captured by the traditional AR(1) autoregressive model. The proposed procedure is described and the bias and MSE of the resulting intercept and slope parameter estimates of the simple LR model …

A Proposed Ridge Parameter To Improve The Least Square Estimator, Ghadban Khalaf

Journal of Modern Applied Statistical Methods

Ridge regression, a form of biased linear estimation, is a more appropriate technique than ordinary least squares (OLS) estimation in the case of highly intercorrelated explanatory variables in the linear regression model Y = β + u. Two proposed ridge regression parameters from the mean square error (MSE) perspective are evaluated. A simulation study was conducted to demonstrate the performance of the proposed estimators compared to the OLS, HK and HKB estimators. Results show that the suggested estimators outperform the OLS and the other estimators regarding the ridge parameters in all situations examined.

Graphical Modeling For High Dimensional Data, Munni Begum, Jay Bagga, C. Ann Blakey

Journal of Modern Applied Statistical Methods

With advances in science and information technologies, many scientific fields are able to meet the challenges of managing and analyzing high-dimensional data. A so-called large p small n problem arises when the number of experimental units, n, is equal to or smaller than the number of features, p. A methodology based on probability and graph theory, termed graphical models, is applied to study the structure and inference of such high-dimensional data.

The Comment finally concludes by arguing for the continued judicial support and more purposeful legislative support of charter schools.

Obtaining Consumer Perceptions Of External Costs Of “Cheap” Food Products And Analyzing Quality Food Markets That Minimize External Costs In Bloomington-Normal, Illinois, Jennifer Long '13

Outstanding Senior Seminar Papers

Today, the United States’ food system is primarily a large industrial operation with smaller-scale community-based food systems. Although the industrial food system has benefitted society by increasing the amount of food available for every person, some of these products are “cheap” food products that generate external costs, such as poor health, potential wealth loss to farmers and environmental degradation. With over 1 billion individuals on earth undernourished and 15.8% of all U.S. households as of 2010 food insecure [Patel, 2012], this system has not completely solved food issues. Community-based food systems, on the other hand, minimize external costs …

A Modified Delay-Time Method For Statics Estimation With The Virtual Refraction, T. Dylan Mikesell, Kasper Van Wijk, Elmer Ruigrok, Andrew Lamb, Thomas E. Blum

CGISS Publications and Presentations

Topography and near-surface heterogeneities lead to traveltime perturbations in surface land-seismic experiments. Usually, these perturbations are estimated and removed prior to further processing of the data. A common technique to estimate these perturbations is the delay-time method. We have developed the “modified delay-time method,” wherein we isolate the arrival times of the virtual refraction and estimate receiver-side delay times. The virtual refraction is a spurious arrival found in wavefields estimated by seismic interferometry. The new method removes the source term from the delay-time equation, is more robust in the presence of noise, and extends the lateral aperture compared to the …

A Multi-Site Case Study Investigating Teacher Perspectives Of Standards Based Reform And Gifted Students, Amy Valadez

Doctoral Dissertations and Projects

The push by the Federal government to directly increase and positively impact achievement since the implementation of No Child Left Behind (NCLB) (2001) gave rise to the educational design known as standards based reform (SBR). This legislation impacted all sub-groups by measuring growth for sub-populations to determine yearly adequate progress. The growth of the sub-population of gifted students, however, was not included in the determination of a school's or county's success, so the impact of standards based reform on the gifted student is lacking. Therefore, this case study examined educators' perspectives of standards based reform on the gifted child in …

Snap-And-Ask: Answering Multimodal Question By Naming Visual Instance, Wei Zhang, Lei Pang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

In real-life, it is easier to provide a visual cue when asking a question about a possibly unfamiliar topic, for example, asking the question, “Where was this crop circle found?”. Providing an image of the instance is far more convenient than texting a verbose description of the visual properties, especially when the name of the query instance is not known. Nevertheless, having to identify the visual instance before processing the question and eventually returning the answer makes multimodal question-answering technically challenging. This paper addresses the problem of visual-totext naming through the paradigm of answering-by-search in a two-stage computational framework, which …

An Analytical And Experimental Comparison Of Csp Extensions And Tools, Ling Shi, Yang Liu, Jun Sun, Jin Song Dong, Gustavo Carvalho

Research Collection School Of Computing and Information Systems

Communicating Sequential Processes (CSP) has been widely applied to modeling and analyzing concurrent systems. There have been considerable efforts on enhancing CSP by taking data and other system aspects into account. For instance, CSP M combines CSP with a functional programming language whereas CSP# integrates high-level CSP-like process operators with low-level procedure code. Little work has been done to systematically compare these CSP extensions, which may have subtle and substantial differences. In this paper, we compare CSP M and CSP# not only on their syntax, but also operational semantics as well as their supporting tools such as FDR, ProB, and …
