Evaluating the Effects of Public Postings on Energy Conservation Behavior at a Public University

Evaluating the Effects of Public Postings on Energy Conservation Behavior at a Public University

Date: August 2011
Creator: Canisz, Eleni
Description: This study evaluated the effects of public postings on energy conservation behavior at a public university, using a multiple baseline design across three settings; bathrooms break rooms, and conference rooms. The behavior of building occupants was recorded to assess the frequency at which those individuals would turn lights off upon exiting an unoccupied room. The independent variables implemented by experimenters (light-switch plate stickers and laminated signs) had little to no effects on cumulative instances of lights turned off however, the installation of motion sensor lights produced better results. Across all conditions, lights were turned off most frequently in conference rooms (65% of observations) followed by break rooms (9% of observations), and bathrooms (3% of observations).

Evaluating the Effects of Video Modeling on the Frequency of Staff Use of Socially Embedded Consequences

Evaluating the Effects of Video Modeling on the Frequency of Staff Use of Socially Embedded Consequences

Date: August 2012
Creator: Yauger, Amy Elizabeth
Description: Previous research reports that individuals working with children with autism can positively affect social behavior through the use of socially embedded consequences. There is no research on training teachers to use socially embedded consequences. The current study had three purposes: to evaluate the effects of video modeling on teachers' embedded consequences, to evaluate the addition of feedback to increase effectiveness, and to evaluate the effects of the teacher's use of socially embedded consequences on other teacher behaviors. Results indicate that video modeling alone was not sufficient in changing teacher behavior and that the addition of feedback was necessary for meaningful teacher behavior change. Additionally, the increased used of socially embedded consequences had positive effects on teacher social engagement and indices of interest. A discussion of the results and suggestions for future research is also provided.

Evaluating the Feasibility of Accelerometers in Hand Gestures Recognition

Evaluating the Feasibility of Accelerometers in Hand Gestures Recognition

Access: Use of this item is restricted to the UNT Community.
Date: December 2014
Creator: Karlaputi, Sarada.
Description: Gesture recognition plays an important role in human computer Interaction for intelligent computing. Major applications like Gaming, Robotics and Automated Homes uses gesture recognition techniques which diminishes the usage of mechanical devices. The main goal of my thesis is to interpret SWAT team gestures using different types of sensors. Accelerometer and flex sensors were explored extensively to build a prototype for soldiers to communicate in the absence of line of sight. Arm movements were recognized by flex sensors and motion gestures by Accelerometers. Accelerometers are used to measure acceleration in respect to movement of the sensor in 3D. Flex sensors changes its resistance based on the amount of bend in the sensor. SVM is the classification algorithm used for classification of the samples. LIBSVM (Library for Support Vector Machines) is integrated software for support vector classification, regression and distribution estimation which supports multi class classification. Sensors data is connected to the WI micro dig to digitize the signal and to transmit it wirelessly to the computing device. Feature extraction and Signal windowing were the two major factors which contribute for the accuracy of the system. Mean Average value and Standard Deviation are the two features considered for accelerometer sensor data ...

Evaluating the Habitat Requirements of the Golden Orb Mussel (Quadrula Aurea) for Conservation Purposes

Evaluating the Habitat Requirements of the Golden Orb Mussel (Quadrula Aurea) for Conservation Purposes

Date: May 2013
Creator: Hammontree, Sarah
Description: Many freshwater mussels are imperiled, due to a number of interrelated factors such as habitat alteration, degradation of water quality, and impoundments. The Golden Orb mussel (Quadrula aurea, I. Lea, 1859) is endemic to the state of Texas and is currently a candidate for the endangered species list, as the number of known populations has been declining in recent years. Little is currently known about Q. aurea aside from basic distribution data. This study is focused on evaluating a combination of macro-habitat and micro-habitat variables to determine their influence on the distribution and density of this species. Macro-habitat variables, including dominant land cover, surface geology, and soil erodibility factor, did not have a significant relationship with mussel distributions. The best model of micro-habitat variables that impacts the Q. aurea distributions is comprised of relative substrate stability (RSS) at moderate flows and current velocity at low flows. For all mussel species in this study, current velocity at low flows is the primary variable that influences distribution. Q. aurea are associated with habitats where larger sediment particles (large gravel and cobble) help to stabilize the substrate in areas with higher current velocities. An understanding of the preferred habitats for Q. aurea can ...

Evaluating the Role of C-reactive Protein on Cognition and Depressive Symptoms Among Women by Mexican American Ethnicity

Evaluating the Role of C-reactive Protein on Cognition and Depressive Symptoms Among Women by Mexican American Ethnicity

Date: August 2014
Creator: Huerta, Serina
Description: C-reactive protein (CRP) is a protein found in the blood that is synthesized by the liver and has been extensively studied due to its role in inflammatory and atherosclerotic processes. The importance of this biomarker in its role in vascular risk factors is increased with several lines of evidence pointing to its association with cognitive decline. The association between CRP and depression has been increasingly analyzed by various cross-sectional studies. The research between CRP and depressive symptoms in older women has yet to generate consistent trends. In the present study, a series of regression analyses was used to explore the association between CRP and both cognitive function and depressive symptomatology among a group of rural-dwelling women. Associations were evaluated through the use of data from Project FRONTIER, a rural-based research looking at both physical and cognitive aspects of health in rural-dwelling adults and elders. Comparisons were made between Mexican American women and a group of non-Hispanic Caucasian women. CRP was a significant independent predictor of total depression (beta = -.11, t = -1.99, p =.048). CRP was also a significant independent predictor of symptoms associated with meaningless within depression (beta = -.16, t = -2.94, p =.004). Contrary to prediction, ...

Evaluating the Role of Design in the Apparel Industry in the United States

Evaluating the Role of Design in the Apparel Industry in the United States

Date: August 2014
Creator: Beard, Diana
Description: The purpose of this study was to better understand the role of design in the product development process in the apparel industry in the United States, looking for variations in how design is used in the industry. In order to obtain a snapshot of the fashion design industry, creativity, originality, innovation, and product development were examined, as well as corporate culture and strategic orientation. The study also sought to examine pedagogical strategies based on these findings. A mixed methods approach, consisting of an on-line survey and interviews, was employed. The findings suggest variations in the role of design based on the time design-department employees spent on creative tasks. These variations were examined and industrial and pedagogical implications are explored. The significance of this study relates to the findings of the importance of creativity in the product development process of the apparel industry in the United States, as well as considerations for pedagogical strategies.

Evaluating the Scalability of SDF Single-chip Multiprocessor Architecture Using Automatically Parallelizing Code

Evaluating the Scalability of SDF Single-chip Multiprocessor Architecture Using Automatically Parallelizing Code

Date: December 2004
Creator: Zhang, Yuhua
Description: Advances in integrated circuit technology continue to provide more and more transistors on a chip. Computer architects are faced with the challenge of finding the best way to translate these resources into high performance. The challenge in the design of next generation CPU (central processing unit) lies not on trying to use up the silicon area, but on finding smart ways to make use of the wealth of transistors now available. In addition, the next generation architecture should offer high throughout performance, scalability, modularity, and low energy consumption, instead of an architecture that is suitable for only one class of applications or users, or only emphasize faster clock rate. A program exhibits different types of parallelism: instruction level parallelism (ILP), thread level parallelism (TLP), or data level parallelism (DLP). Likewise, architectures can be designed to exploit one or more of these types of parallelism. It is generally not possible to design architectures that can take advantage of all three types of parallelism without using very complex hardware structures and complex compiler optimizations. We present the state-of-art architecture SDF (scheduled data flowed) which explores the TLP parallelism as much as that is supplied by that application. We implement a SDF single-chip ...

Evaluating Tree Seedling Survival and Growth in a Bottomland Old-field Site: Implications for Ecological Restoration

Date: August 2007
Creator: Boe, Brian Jeffrey
Description: In order to assess the enhancement of seedling survival and growth during drought conditions, five-hundred bare-root seedlings each of Shumard oak (Quercus shumardii Buckl.) and green ash (Fraxinus pennsylvanica Marsh.) were planted each with four soil amendments at a Wildlife Management Area in Lewisville, Texas. The treatments were a mycorrhizal inoculant, mulch fabric, and two superabsorbent gels (TerraSorb® and DRiWATER®). Survival and growth measurements were assessed periodically for two years. Research was conducted on vegetation, soil, and site history for baseline data. Both superabsorbent gels gave significant results for Shumard oak survival, and one increased green ash diameter. For overall growth, significant results were found among DRiWATER®, mycorrhizae, and mulch treatments.
