Early information is crucial for policy makers and public health officials responsible for protecting the public from the virulent spread of contagious diseases. Current indicators of the spread of contagious outbreaks lag behind the actual spread...
Sensor networks are just in their infancy. Their use will continue to grow as the technology becomes cheaper and more efficient. A current shortcoming with sensor networks is the inability to efficiently provide secure communications. As sensor...
Drug resistance in microorganisms--Mathematical models; Intensive care units
Antibiotic resistance is a problem causing growing concern in the medical community, leading some to speculate that a return to the preantibiotic era is imminent. The problem of antibiotic resistance is particularly significant in the intensive...
Rising concerns about dependency on fossil fuels in the 21st century has sparked a growth in research for renewable energy sources. One renewable energy production process of interest is the reduction of cellulose into fermentable sugars by means...
The Combinatorial Nullstellensatz can be used to solve certain problems in combinatorics. However, one of the major complications in using the Combinatorial Nullstellensatz is ensuring that there exists a nonzero monomial. This dissertation looks...
Hemolysis, the major cause for specimen rejection in clinical laboratories is defined as the rupture of red blood cell membranes, resulting in the release of hemoglobin into the plasma. Blood flow in needles causes hemolysis resulting in...
Crossover design is a type of longitudinal study with each subject receiving different treatments in different time periods. It has been used frequently in the pharmaceutical industry and other medical fields to investigate the safety and efficacy...
Mixed-effects model is an efficient tool for analyzing longitudinal data. The random effects in mixed-effects model can be used to capture the correlations among repeated measurements within a subject. The time points are not fixed and all...
Wheel Slide Protection Systems (WSP Systems) or Anti-Skid Devices for rail vehicles have to go through a series of Dynamometer tests before test runs with equipped rail vehicles are permitted. The simulation tests are performed on Wheel Slide...
Clustered longitudinal data is often collected as repeated measurements on subjects over time arising in the clusters. Examples include longitudinal community intervention studies, or family studies with repeated measures on each member. Meanwhile,...
The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...
DNA microarrays--Statistical methods; Gene expression--Statistical methods
Data derived from gene expression microarrays are frequently used to identify candidate genes which can characterize and distinguish between two biological phenotypes. A key step in this process is the selection of an appropriate test statistic to...
This study focuses on the variation in structural response to synthetic ground motions derived from the latest attenuation models developed for the Central Eastern United States (CEUS) and used by the USGS to develop the latest edition (2008) of...
In this dissertation research, we aim to solve problems of two types of survival data, clustered survival data with potentially informative cluster size and sojourn time data. The methods for these two types of data are different. However, both...
Item response theory; Goodness-of-fit tests; Monte Carlo method
Item response theory (IRT) is expanding to diverse research settings, without accompanying access to easily implemented model fit methods. One simple model fit approach involves x2/df ratios. However, its utility is not known across several...
This thesis is written to investigate if and how far the German credit financial market could be promising for consulting fees in the field of mortgage loan banking. The problem identified is an extensively discussed issue in the German credit...
This study expands our efforts to make a new class of Pt (II) compounds analogous to cisplatin and its derivatives using sterically hindered ligands. Pt compounds in this series have been synthesized using specially designed pyridine and...
We formulate an integro-difference model to predict the growth and spatial
spread of a perennial plant population with an age-structured seed bank. We allow
the seeds in the bank to be of any age, producing an infinite system of equations.
The...
All terrain vehicles--Automatic control; Motor vehicles--Automatic control; Intelligent control systems
When tracked vehicles traverse terrain such as sand, soil, or even concrete,
they may encounter a variance in density or viscosity of the medium that the
vehicle is traveling along. When this happens, one track begins to move faster or
slower...
Industrial management--Data processing; Supervision of employees--Data processing; Decision making--Data processing
This paper models a realistic problem involving workforce assignment and training for a large manufacturing environment. In this particular environment, the workforce is undertrained and most assignments will result in necessary training. This...
