abstract: The stadiometer is the gold standard human height measure, but recent studies have begun to question whether laser technology is a better tool to measure height. The purpose of this study was to investigate if the laser device has inter-rater reliability, how the laser-device measures supine height in comparison to standard methods, and if the laser device will be consistent in measuring human height shorter, as seen in previous studies. Two investigators measured a total of 80 adults independently. Measurements included knee height, arm span, demi span, supine height by laser, standing height by laser and standing height by stadiometer. There was a strong inter-rater reliability for the laser height measurement: excluding one outlier r=0.998. Supine height measures done with a laser were strongly correlated with arm span, but mean values were closest between supine height and knee height (171.3cm and 171.2cm). The laser measured standing height 0.5cm shorter, on average, than the stadiometer. It is concluded that the laser device is a reliable, validated tool to measure human height, standing or supine. / Dissertation/Thesis / Masters Thesis Nutrition 2016

Off-target deposition of herbicides to non-target plant species has been extensively studied and well documented over time. Off-target movement can often be detrimental to plant growth and yield. The geography of Mississippi is favorable for off-target herbicide deposition due to many crops existing in close proximity to differing crops such as soybeans (Glycine max L.) and rice (Oryza sativa L.). Therefore, research was conducted in each of three locations in Mississippi in 2016 and 2017 to determine if enhanced ALS-tolerant soybeans could be used to mitigate off-target deposition of rice herbicides penoxsulam and bispyribac-sodium. Results indicate that this technology (specifically BOLT soybean) can be utilized if herbicide residue is below 1/16X of the full labeled rate and is not deposited at V3 or early reproductive growth stages (R1-R4).

Many human traits and diseases have a polygenic architecture, where phenotype is partially determined by variation in many genes. These complex traits or diseases can be highly heritable and genome-wide association studies (GWAS) have been relatively successful in the identification of associated variants. However, these variants typically do not account for most of the heritability and thus, the genetic architecture remains uncertain.

As técnicas de posicionamento Global Navigation Satellite System (GNSS) proporcionam o conhecimento das altitudes de forma rápida e fácil; porém, a componente fornecida por estas técnicas possui caráter geométrico, ou seja, a altitude corresponde à distância normal entre o ponto mensurado e o elipsoide de revolução. Esta altitude tem sua importância, porém não possui caráter físico. Em obras de engenharia, é fundamental o conhecimento da altitude física, pois é a do sentido de escoamento da água. Este fator físico corresponde ao geopotencial, que quando relacionado com dados gravimétricos resulta em uma altitude física que representa a distância entre a superfície equipotencial do ponto de interesse e a superfície equipotencial de referência. Em 2015, a International Association of Geodesy (IAG) publicou uma resolução de fundamental importância na integração dos sistemas de altitudes entre os países, visando à formação de um Sistema Internacional de Referência Altimétrico, o International Height Reference System (IHRS). Dessa forma, para que as altitudes possam ser integradas ao IHRS é necessário calcular o valor do geopotencial. Os dados gravimétricos disponíveis no estado de São Paulo possibilitaram o cálculo do geopotencial, uma vez que o estado possui distribuição gravimétrica homogênea, que é uma das sugestões de condições para determinar o valor do potenci...

Global Navigation Satellite System (GNSS) techniques provide the heights quickly and easily; however, the component provided by these techniques has a geometric character, that is, the height corresponds to the normal distance between the measured point and the revolution ellipsoid. This height has its importance, but it does not have physical meaning. In engineering works, it is fundamental to know the physical height, because it is the one that the direction of water flow obeys. This physical factor corresponds to the geopotential, which when related to gravimetric data results in a physical height. Represents the distance between the equipotential surface of the point of interest and the equipotential reference surface. In 2015, the International Association of Geodesy (IAG) published a resolution of fundamental importance in the integration of height systems between countries, aiming at the formation of a global altimetric system, the International Height Reference System (IHRS). Thus, in order for the heights to be integrated into the IHRS, it is necessary to calculate the potential value. Thus, considering the importance of integrating Brazilian heights with a global system, the geopotential number for the PPTE and NEIA stations in the state of São Paulo was calculated. In these calculations were applied the Global Geopotential Models (GGMs) EIGEN-6C4, GECO, GOCO05c ... (Complete abstract click electronic access below) / Mestre

Many graphics applications today have need for high-speed 3-D visualization of height fields. Most of these applications deal with the display of digital terrain models characterized by a simple, but vast, non-overlapping mesh of triangles. A great deal of research has been done to find methods of optimizing such systems. The goal of this work is to establish an algorithm to efficiently preprocess a hierarchical height field model that enables the real-time culling of occluded geometry while still allowing for classic terrain-rendering frameworks. By exploiting the planar-monotone characteristics of height fields, it is possible to create a unique and efficient occlusion culling method that is optimized for terrain rendering and similar applications. Previous work has shown that culling is possible with certain regularly-gridded height field models, but not until now has a system been shown to work with all height fields, regardless of how their meshes are constructed. By freeing the system of meshing restrictions, it is possible to incorporate a number of broader height field algorithms with widely-used applications such as flight simulators, GIS systems, and computer games.

Suspensions play a crucial role in vehicle comfort and stability. Different types of suspensions have been proposed to fulfill the essential characteristics of vehicle suspensions. A semi-active suspension with adjustable damper improves the performance of a suspension in different conditions and it is better than a passive suspension in terms of ride comfort and handling. Furthermore, it is not as expensive and complicated as an active suspension. Semi-active suspensions rely on adjustable damping coefficient. A new type of air suspension with independent ride height and stiffness tuning has been developed recently. By using two air chambers in the suspension system, ride height of vehicle and stiffness of suspension can be adjusted independently and simultaneously. The conventional air suspension systems use compressor to pump the air into a single flexible rubber airbag and by inflating the air, the chassis will be raised from the axle (ride height control). In this type of suspensions, the stiffness of spring is not under control. In the new air suspension system, by controlling the air pressure on both chambers, one can tune the suspension stiffness and the ride height of the vehicle at the same time for different driving conditions. The air suspension is also able to maintain the vehicle body at the same height and natural frequency for different load or number of passengers. This thesis discusses about the design analysis of an air suspension with ride height and stiffness tuning. The analytical formulation is developed for the optimum design of the new air suspension system. In this thesis, the interconnection between the pressurized chambers of the new air suspension with ride height and stiffness tuning is studied to further improve the performance. Proper interconnection of air springs can help the suspension system to distribute the load between tires more evenly on rough roads or uneven surfaces. Different configurations in air spring interconnection have different impact on the handling and tire load distribution. To study the effect of air spring interconnection configurations on tires load distribution and vehicle handling, a general mathematical model is developed. This model is used to compare various configurations in detail. Results show that interconnection could improve tire load distributions greatly. It is also shown that improving tire load distribution will deteriorate roll stiffness that in turn deteriorate vehicle handling at higher speeds. Since on rough roads, vehicle’s speed is necessarily low, interconnection will not have adverse effects on vehicle handling when activated.
