This thesis sets out to derive an analytical model for a center of gravity (CG) measuring platform and examines its validity through experimental testing and Finite Element Modeling. The method uses a two-stage platform tilting process to first locate the planar CG coordinates and then find the third CG coordinate normal to the platform. An uncertainty model of the measuring platform was also developed, both CG and uncertainty models were implemented in the form of a MATLAB code. A load cell sizing task was also added to the code to assist the Integration Engineers at Jet Propulsion Laboratory

This study aims to validate a screw joint simulation model used by BAE Systems in LS-DYNA during blast simulations. It is important that the screw joint simulation model is physically correct, since the simulation results can influence major design decisions. The study provides a short overview on the subject of bolts and screws, material deformation and stress and strain in materials, of the finite element method (FEM) and on some specific numerical methods used in this study. BAE Systems started a validation project of the screw joint simulation model in 2015, but it was not finished due to

Studies are currently being performed to determine the effects of bisphosphonate treatments on the structure and density of bone tissue. One of the pathways for gaining a better understanding of the effects of this and other treatments involves creating a computer simulation. Theory suggests that bone tissue structure and density are directly related to the manner in which the tissue is loaded. Remodeling is the process in which bone tissue is resorbed in areas of low stress distributions, and generated in areas of high stress distributions. Previous studies have utilized numerical methods

The insertion loss for a number of different plenum geometries was compared to published measurement results. Results were in good agreement bo

It has been recognized that small molecules can affect a substantial proportion of the human transcriptome in ways that are currently unknown and difficult to predict. Working with the Broad Institute, using their Connectivity Map database, we have worked to identify compounds anticipated to modulate two diseases; myotonic dystrophy (DM1) and Duchenne muscular dystrophy (DMD). DM1 stems from an expanded CTG repeat found in the DMPK gene. The down regulation of DMPK mRNA represents a valid therapeutic avenue.

Nos contributions portent sur trois volets : la spécification des exigences, la modélisation du comportement et la vérification. Pour le volet spécification, une nouvelle classification des exigences temporelles les plus communément utilisées a été proposée. Ensuite, afin de cadrer l’utilisateur durant l’expression des exigences, une grammaire de spécification à base de motifs prédéfinis en langage naturel est développée. Les exigence

Annotation:

Droop-Nose Leading Edge (DNLE) morphing wings are one of the most promising devices in order to achieve aerodynamic drag and noise reduction during take-off and landing phases. An accurate design of these structures could lead to the decrease of aircraft fuel consumption in the perspective of reaching a greener aviation, following the objectives indicated by Flightpath 2050 issued by the E.U. However, due to the challenges related to the realization of this technology and TRL reached, DNLE are more likely implemented in Unmanned Aerial Systems (UAS) for testing and evaluation purposes.

This research into Chronic Fatigue Syndrome (CFS) presents the results of 60 first-person psycho-phenomenological interviews with 30 New Zealand women. The participants were recruited from the Canterbury and Wellington regions, 10 had recovered. Taking a non-dual, non-reductive embodied approach, the phenomenological data was analysed semiotically, using a graph-theoretical cluster analysis to elucidate the large number of resulting categories, and interpreted through the enactive approach to cognitive science. The initial result of the analysis is a comprehensive exploration of the experienc

Honeycomb materials possess high energy absorption characteristics and are useful for the impact protection of structural members. Various honeycomb configurations are being developed for a variety of applications. Analytical models are now available to determine the energy absorption characteristics of the regular hexagonal type of honeycomb. However, the development a parameterized analytical model that can determine the energy absorption characteristics of various honeycomb shapes is needed. In this research, a parameterized analytical model is developed for the typical honeycomb shape, and

The specification of the wind turbine generator is determined for Taiwan’s low wind conditions. An accurate magnetic circuit model (MCM) is constructed for BDFIM. The model can rapidly calculate the dimension of BDFIM by taking saturation into account and calculate the machine parameters without time-consuming finite element analysis (FEA). By combining the MCM and an equivalent circuit model (ECM), the BDFIM can be properly designed.

The fear appeal, a message that attempts to influence behavior through the threat of some danger, is one such type of marketing communication. The power of such appeals seems obvious; all that should be required to influence an individual''s behavior is to make that person aware of the danger or dangerous behavior. Marketers have attempted to take advantage of this relationship by using the threat of danger to evoke the emotional response of fear and thus influence behavior.To date, resear

Annotation:

Liver cancer is one of the leading causes of death worldwide. One of the reasons for that is the high tumor recurrence rate. The only way to reduce the recurrence rate is to ensure that all carcinogenic cells are destroyed after intervention. Unfortunately, the information available to assess the outcome of an intervention is limited. In the clinical routine, a pair of pre- and post-operatively gathered computed tomographies (CT) of the abdomen are typically compared to decide whether the patient needs further treatment. However, the post-operative liver will be deformed due to breathing and i

Tropical pastures are dominated by tropical or C4 grasses, which supply most of the forage material for grazing meat goats. In the typically long dry season of Northern Australia and West Timor, Indonesia, these grasses contain crude protein (CP) of 20 to 100 g/kg DM. This is equivalent to metabolisable protein (MP) content of 10.5 to 60.9 g/kg DM and metabolisable energy (ME) of 6.2 to 9.1 MJ/kgDM. These cannot meet the goats' requirements for MP and ME as recommended by the National Research Council (NRC) 2007. These nutritional issues cause low productivity in periparturient does for breedi
