Integrating Radiant Flooring With Insulation, Zachary J. Faber

Construction Management

Radiant flooring has gained traction in recent years becoming very common in residential construction, especially in custom homes. There are different types of radiant flooring that has been deployed into the construction of residential homes, but not all of them have been effective. Currently, radiant flooring must be installed either during construction of a new home, or requires the removal of existing flooring in order to place radiant components below and then reinstall the flooring. Not only does it require the removal of flooring, it is also quite expensive to purchase and install. This paper looks into whether or not …

Case Study: Mitigating Schedule Impacts From Oshpd Regulations On Medical Equipment, Peter K. Lee

Construction Management

The vast majority of healthcare construction projects in the state of California work with OSHPD—Office of Statewide Health Planning and Development—to meet California’s Hospital Seismic Safety Law. While meeting the state’s Hospital Seismic Safety Law is important and even critical, working with OSHPD’s stringent regulations does imply additional concerns to be addressed by the project team. One concern regards the approval of bigger medical equipment and its impact on the overall construction schedule. This paper examines the factors that contribute to delays in the construction schedule, responsible parties for the delay, and responsibilities of each involved party. Based on an …

As the number of cyber-attacks continues to grow on a daily basis, so does the delay in threat detection. For instance, in 2015, the Office of Personnel Management discovered that approximately 21.5 million individual records of Federal employees and contractors had been stolen. On average, the time between an attack and its discovery is more than 200 days. In the case of the OPM breach, the attack had been going on for almost a year. Currently, cyber analysts inspect numerous potential incidents on a daily basis, but have neither the time nor the resources available to perform such a task. …

Liureg: A Comprehensive R Package For The Liu Estimation Of Linear Regression Model With Collinear Regressors, Muhammad Imdadullah, Muhammad Aslam, Saima Altaf

The R Journal

The Liu regression estimator is now a commonly used alternative to the conventional ordinary least squares estimator that avoids the adverse effects in the situations when there exists a considerable degree of multicollinearity among the regressors. There are only a few software packages available for estimation of the Liu regression coefficients, though with limited methods to estimate the Liu biasing parameter without addressing testing procedures. Our liureg package can be used to estimate the Liu regression coefficients utilizing a range of different existing biasing parameters, to test these coefficients with more than 15 Liu related statistics, and to present different …

Furniture For Quantitative Scientists, Tyson S. Barrett, Emily Brignone

The R Journal

A basic understanding of the distributions of study variables and the relationships among them is essential to inform statistical modeling. This understanding is achieved through the computation of summary statistics and exploratory data analysis. Unfortunately, this step tends to be under-emphasized in the research process, in part because of the often tedious nature of thorough exploratory data analysis. The table1() function in the furniture package streamlines much of the exploratory data analysis process, making the computation and communication of summary statistics simple and beautiful while offering significant time-savings to the researcher

Allele Imputation And Haplotype Determination From Databases Composed Of Nuclear Families, Nathan Medina-Rodríguez, Ángelo Santana

The R Journal

The alleHap package is designed for imputing genetic missing data and reconstruct non recombinant haplotypes from pedigree databases in a deterministic way. When genotypes of related individuals are available in a number of linked genetic markers, the program starts by identifying haplotypes compatible with the observed genotypes in those markers without missing values. If haplotypes are identified in parents or offspring, missing alleles can be imputed in subjects containing missing values. Several scenarios are analyzed: family completely genotyped, children partially genotyped and parents completely genotyped, children fully genotyped and parents containing entirely or partially missing genotypes, and founders and their …

You're A Genius All The Time: Analyzing The Effectiveness Of Kerouac's Spontaneous Prose On Empowering English Language Learners, Robert Casas

Theses and Dissertations

The engineer of the Beat Movement, Jack Kerouac, began his writing career as an ELL. Kerouac’s Spontaneous Prose helped him navigate through language acquisition to establish rhetoric in English, and empowered other Beat Writers to expressively develop their thoughts. Spontaneous Prose can also help other ELLs develop their own rhetorical agency. For ELL writers, writing in English often makes them feel disenfranchised, disempowered, and discouraged. However, Spontaneous Prose as a pedagogical tool empowers ELL writers to begin the process of transculturally repositioning themselves in using writing as a form of rhetorical expression. This study investigates the pedagogical effectiveness of Spontaneous …

Three Flute Chamber Works By Alberto Ginastera: Intertwining Elements Of Art And Folk Music, Breta L. Neel

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

Alberto Ginastera’s output includes three chamber works containing the flute, all composed within the period of objective nationalism (1934-1947), a designation provided by the composer to encompass those works that present folk elements in an overt manner in a largely tonal framework. Impresiones de la Puna and Cantos del Tucumán, written in 1934 and 1938 respectively, contain salient folk elements and are thus representative pieces of this stylistic period. In addition to folk characteristics, these early works also contain pitch-class sets which serve to unify the pieces, thereby suggesting future elements of the composer’s style. The Duo for Flute …
