Abstract:

The purpose of this study was to understand the relationship between back squat one-repetition maximum relative to body mass (1RMrel), countermovement jump height (CMJH), and optimal drop height in drop jump (DHopt). Fifteen male participants with various sport backgrounds and training experience completed a one repetition maximum (1RM) back squat, maximum countermovement jump (CMJ), and drop jumps (DJ) from incrementally increasing drop heights to determine which drop height elicited the greatest jump height. The DHopt testing protocol was unique in that smaller increments were used to determ

Abstract:

Full time wheelchair users are at a height disadvantage during many function activities, such as transferring or reaching. Retrieving objects from the ground or a higher shelf while seated in the wheelchair can be both difficult and unsafe. Lateral transfers between surfaces at different heights can be difficult and unsafe. Sit-to-stand transfers are made simpler with a higher seat. This research project seeks to assist reach and transfers by designing a system to raise and lower a wheelchair seat over a 4'' range. The project included several needs assessment: 1) by conducting interviews and

Abstract:

Postural threat induced by height affects the control of movement. The aim of this thesis was to develop a better understanding of the extent and the mechanisms through which postural threat can affect movement. The first study showed that a postural threat induced with a height of 80 cm (walkway width 22 cm) did not affect the gait pattern or arousal levels of young healthy adults. Whereas a height of 3.5 m did, an increase in arousal and a more cautious gait pattern compared to walking at ground level were observed. The influence of visual information was tested by occluding visual informati

Abstract:

Bumblebees are a group of valuable pollinators that are declining all over the world. The main reason is believed to be habitat loss due to the changes in agriculture. The changes in agriculture influence the structure of the vegetation and flower abundance, which are of great importance to the abundance of bumblebees. The aims of this study were to get a better understanding of bumblebees and what preferences they might have regarding vegetation height and flower abundance in semi-natural grasslands.

Over-height trucks are not only a hazard to the over-height trucks themselves, but they pose a threat to the bridges they come into contact with, and most importantly the other drivers on the road way when a collision takes place with a low clearance structure. Therefore, there is a need for an over-height detection system that is affordable yet also reliable. At this time there exist over-height detection systems using laser and infrared beam devices however, they are expensive. This high cost makes it impossible for Department of Transportations across the nation to implement these systems a

This gives a geopotential height at any isolated field point where there is a Global Navigation Satellite System (GNSS) measurement without reference to a vertical network or a regional datum point. Previously, height was determined conventionally by connecting the desired field point physically to a nearby bench mark of a vertical network using co-locat

Shoot length was reduced 46 %; stem dry weight was reduced 31 %; leaf area per shoot was reduced 44 %; inflorescence height was cut by 45 %; and inflorescence mass was reduced 48% with the 30 mg-liter⁻¹ XE-1019 treatment.

Abstract:

The full height truss frame (FHTF) is an exciting new residential framing system in response to the need for low floor-to-floor steel construction. The FHTF has the potential to provide low floor-to-floor heights, a column free first floor area, an integrated frame that uses the entire height to resist loads, and the capacity to resist both gravity and lateral loads. Because of its configuration, the full structural height can be used to resist loads. A FHTF is made up of stacked floor trusses that result in one full height truss spanning the entire width of the building. The FHTF is con

Height estimation of objects can be implemented both for soft-biometrics and as an object tracking feature. In first case we can eliminate some possible subjects having considerably different height than the observed one, and focus on determining more distinctive remote identification features, like colour, face or ear, and search for similar subjects in a smaller set of possible candidates. For object tracking it can be used for temporal and spatial correspondence analysis as well or simultaneously for both in case of having different cameras.

Abstract:

A floating island was generated using two height maps, one for the bottom of the island and one for the top. Vertices of the island was displaced in the Y axis using an algorithm called Simplex noise. To avoid texture stretching that appears when displacing the vertices an algorithm called “tri planar projection” was implemented. After the vertices had been displaced the normal was smoothed using “normal smoothing”. An algorithm here called “the AVG algorithm” is created to smooth jig sawed edges around the island that appears after the island has been generated. The results of the AVG algorit

Abstract:

External flaming from buildings occurs as a result of a large amount of fuel being available in the room of fire origin in comparison to the amount of ventilation provided. The size of the openings in a compartment affects the amount of oxygen available within the fire room, and hence the amount of combustion that can take place inside. Excess fuel that is not burnt within the room flows out of the opening and combusts upon reaching the oxygen in the air outside. It is in this situation that flames are seen projecting out of the window. Flames projecting from openings pose the threat of fire s

Abstract:

We consider five separate problems in finite group theory which cover a range of topics including properties of 2-generated subgroups, permutation groups, fixed-point-free automorphisms and the study of Sylow structure. The treatments of these problems are largely self-contained, but they all share an underlying theme which is to study finite soluble groups in terms of their Fitting height. Firstly, we prove that if A is a maximal subgroup of a group G subject to being 2-generated, and V <\(_-\) G is a nilpotent subgroup normalised by A, then F*(A)V is quasinilpotent.

Abstract:

The change of ionospheric absolute reflection heights h of low-frequency (LF) radio waves at oblique incidence in the course of the day is measured at Collm Observatory (51.3°N, 13.0°E) using 1.8 kHz sideband phase comparisons between the sky-wave and the ground wave of a commercial 177 kHz transmitter (Zehlendorf, reflection point 52.1°N, 13.2°E). Plasma scale height estimates H are calculated from the decrease/increase of h in the morning/evening. The day-to-day variations of H are compared with those of daily mean temperatures at 90 km, measured with a VHF meteor radar (36.2 MHz) at Collm u

Abstract:

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 characteris

Abstract:

A great interest in 3-D modeling in Geographic Information Technologies (GIS) has emerged in recent years, because many GIS related implementations, ranging from urban area design to environmental analysis require 3-D models. Especially the need for 3-D models is quite urgent in urban areas. However, numerous applications in GIS only represent two-dimensional information. The GIS community has been struggling with solving complex problems dealing with 3-D objects using a 2-D approach. This research focused on finding most accurate method which is used for getting height information that is use
