Convertability And Oil Resistance Of Paperboard With Hydroxypropyl-Cellulose-Based Dispersion Barrier Coatings, Ville Leminen, Sami-Seppo C. Ovaska, Panu Tanninen, Juha Varis

Journal of Applied Packaging Research

The convertability and barrier properties of paperboard coated with hydroxypropyl-cellulose (HPC) based dispersions were studied via tray pressing trials, oil resistance measurements and microscopic analyses. To improve the oil resistance of the HPC-based coatings and to maximize their convertability, talc, gelatin and latex were used as additives in coating formulations. The oil resistance of the coatings improved to some extent with these additives, but scanning electron micrographs revealed the existence of pinholes particularly in coatings with a high HPC content. The coated paperboard samples were pressed into rectangular trays and the convertability of the paperboards was evaluated with a microscope. …

Workload In Nursing: A Descriptive Study Using Cognitive Work Analysis, Jonathan Umansky

Pulsed Photonic Curing Of Conformal Printed Electronics, Sourav Das

Theses

As next-generation electronic products emerge, there is a need to create more electronic functionality in compact spaces. One of the techniques to achieve this is by integrating electronic circuitry on mechanical stress bearing parts of electro-mechanical products. Direct-write printing processes like inkjet printing and aerosol jet printing can be used to print conductive inks on conformal surfaces of mechanical components. Advanced curing/sintering processes such as pulsed photonic curing can be used to cure/sinter printed inks to produce conductive traces. However, the use of photonic curing on conformal surfaces introduces two sources of variability into the process, which are the distance …

Developing An Algal Biofilm Filtration System For The Remediation Of Nutrient Pollution In Freshwater Ponds, Danielle Delp

Theses

Anthropogenic nutrient pollution is one of the most serious threats facing aquatic systems in modern times. Pollution with compounds containing nitrogen and phosphorous encourages rapid development of autotrophic biomass, or blooms, that severely degrade the quality of an aquatic system both as a habitat for organisms and as a water resource for human use. In freshwater ponds, the widespread need for treatment of nutrient pollution and resulting blooms has resulted in the growth of a large industry dedicated to pond management and maintenance. These companies utilize a variety of chemical and non-chemical treatments to prevent the growth of blooms or …

Numerical Investigation Of Parameters Impacting The Wall Thickness Of Carbon Nanotubes Manufactured By Template-Based Chemical Vapor Deposition, Yashar Seyed Vahedein

Theses

Template-based chemical vapor deposition (TB-CVD) is a versatile technique for manufacturing carbon nanotubes (CNTs) or CNT-based devices for various applications. In this process, carbon is deposited by thermal decomposition of a carbon-based precursor gas inside the nanoscopic cylindrical pores of anodized aluminum oxide (AAO) templates to form CNTs. Experimental results show CNT formation in templates is controlled by TB-CVD process parameters, such as time, temperature and flow rate. Optimization of this process is done empirically, requiring tremendous time and effort. Moreover, there is a need for a more comprehensive and low cost way to characterize the flow in the furnace …

The Use Of Landsat 8 For Monitoring Of Fresh And Coastal Waters, Javier A. Concha

Theses

The most interaction between humankind and water occurs in coastal and inland waters (Case 2 waters) at a scale of tens or hundred of meters, but there is not yet an ocean color product (e.g. chlorophyll-a product) at this spatial scale. Landsat 8 could potentially address the remote sensing of these kinds of waters due to its improved features. This work presents an approach to obtain the color producing agents (CPAs) chlorophyll-a, colored dissolved organic material (CDOM) and suspended material (SM) from water bodies using Landsat 8. Adequate atmospheric correction becomes an important first step to accurately retrieving water parameters …

Multiple Collections, William Thomas Tighe

My interest in history and collecting unique objects from the past have heavily influenced …

Measuring Physiological Arousal Towards Packaging: Tracking Electrodermal Activity Within The Consumer Shopping Environment, Rupert Andrew Hurley, Dan E. Hutcherson, Charles E. Tonkin, Shaundra B. Dailey, Julie C. Rice

Journal of Applied Packaging Research

Contrasted against the popular belief that consumers make purely rational decisions, purchasing decisions are rapid, subconscious, and emotional decisions. In order to understand a consumer’s purchasing decisions, we suggest finding methods beyond focus groups, which typify this type of research, to measure and interpret consumer reactions to various packaging designs. In this paper, we examine electrodermal activity, a measure of emotional arousal, and eye tracking in the context of a realistic shopping environment as possible measures to support insight into customer preference of packaging. We hypothesized that presenting consumers with an experience more closely related to actual shopping would encourage …

Recursive Model Selection For Gnss-Combined Precise Point Positioning Algorithms, Andrew Tollefson

Theses

The accuracy of Global Positioning algorithms can be improved by incorporating observations from the satellites of multiple Global Navigation Satellite Systems (GNSS). To best utilize these observations, inter-system biases must be modeled. A unified observational model is proposed which accounts for these factors for an arbitrary number of GNSS. The Bayesian Information Criterion (BIC) may be imposed upon the unified model to balance data-fitting degree with model complexity among candidate models for a given satellite configuration scenario. A simple formulation is derived for the change to the Weighted Sum Squared Residuals (WSSR) outcome caused by modifying the least-squares design matrix …

Effects Of Persuasive Communication On Intention To Save Energy: Punishing And Rewarding Messages, Michell Patricia Garcia Mera

Theses

Communication can be used to persuade individuals to change their intentions. This study analyzes the use of rewarding and punishing messages for the purpose of changing intention towards energy saving. It also analyzes the use of social and individual rewards and punishments and their effects in motivating behavioral change positively towards energy saving. Results show that while reward and punishment are both effective in manipulating intention positively towards energy saving behaviors, overall there is no significant difference between the two. However, when individual reward was compared to individual punishment, individual punishment was found to be more effective than reward in …

A Generalized Model Of Cognitive Workload, Taylor Carpenter

Theses

Numerous catastrophic accidents have been the result of human operators making poor judgement calls stemming from suboptimal decision making. This suboptimal decision making, in many cases, arises when an operator is either in a high cognitive workload state, overwhelmed with information leading to a greater chance of missing an important detail, or in a low cognitive workload state, distracted and overall not paying attention to the task at hand. If the cognitive workload of an individual can be properly monitored, suboptimal operator conditions can be recognized or prevented, reducing the chance of an accident. While previous research has led to …

Effect Of Simulated Canopy Cover On Created Vernal Pools In The Northeastern Us, Elizabeth Anne Bruen

Theses

Vernal pools in the Northeastern United States are small, forested wetlands characterized by ephemeral flooding. These unique ecosystems provide critical habitat for both terrestrial and aquatic organisms, abate seasonal flooding, and are biogeochemical hotspots. Vernal pools may be created to maintain key ecosystem services associated with loss of natural wetlands. In many instances, however, created pools do not mimic the ecological functions and services of extant vernal pools due to shortcomings associated with the surrounding land use and canopy cover, hydrology, or invasion by opportunistic plants. Because of the importance of these systems to regional biodiversity, understanding the conditions required …

Critical Action, Zachary Dietl

Theses

Critical Action is an examination of pluralism in how artworks are judged. As artworks are often equivocal, so too are our beliefs about them. I claim that because of varying levels of knowledge, experiences, tastes, or other biases, an artwork exists in as many contexts as it has viewers. In order to better identify the ways that judgements are formed, I made a series of self portraits and performed a transforming action on each of them. Each action is designed to critique a perceived quality in or adjacent to the work. The portraits are pushed into new modes of understanding …

Out Of Sync: Live Visual Performance Design, Charles Miller

Theses

Live visual performances are often combined with and serve as enhancement to musical performances. As a result, visual content is informed by, and responds to audio content. How does the situation change if the performance is based around visuals? Can audio accompaniment be performed independently, and the two come together during performance? Without a musical subtext, what form will the visuals take? What would be the ideal performance environment for optimal creative freedom and control of performance parameters?
