Abstract:
Herd simulation model was adopted to assess the productivity of Muturu cattle under sedentary pastoral system within southeast, Nigeria. The model involved biomass and other productivity investigations of the Muturu herds on field-gazed and stall-fed management within the wet and dry season period. Biological entities of Muturu herds from 500 Muturu cattle holders (MCH) and Non-Pastoral holders (NPH) surveyed from year 2010 to 2019 were studied. The sedentary production system was simulated and statistically analyzed. The results showed 70 percent MCH and 30 percent NPH, with60 percent of the Muturu stock sourced through donation/leasing arrangement by the NPH, while only 5 percent of the stock for the study was through purchase arrangement by the MCH. Sedentary pastoral system in southeast Nigeria operates at a very low commercial level. There were significant differences (P<0.05) in some of the biological entities such as live weight at 12 and 24 months, which were better in the wet season than in the dry season. The stall-fed management was relatively better than the field grazed management. Simulated values were higher than the actual values in some of the biological entities but fit in with field grazed and stall-fed management. The efficiency of Livestock/forage production under the sedentary system was very low with 13.02, 15.32 and 17.35 percent respectively for field-grazed, stall-fed management and simulation model. The herd biomass and productivity values of Muturu herd under the sedentary pastoral system in the Southeast region were very low with 25.00 and 33.33 percent for field grazed and stall-fed management respectively. Un modèle de simulation de troupeau a été adopté pour évaluer la productivité des bovins Muturu sous système pastoral sédentaire dans le sud-est du Nigeria. Le modèle impliquait des études sur la biomasse et d'autres études de productivité des troupeaux de Muturu sur la gestion surveillée sur le terrain et nourrie en stabulation pendant la période de saison humide et sèche. Les entités biologiques des troupeaux Muturu de 500 éleveurs Muturu (le 'MCH') et non pastoraux (le 'NPH') enquêtés de 2010 à 2019 ont été étudiées. Le système de production sédentaire a été simulé et analysé statistiquement. Les résultats ont montré 70 pour cent de 'MCH' et 30 pour cent de 'NPH', avec 60 pour cent du stock de Muturu provenant d'un accord de don / location par le 'NPH', tandis que seulement 5 pour cent du stock de l'étude provenait d'un accord d'achat par le 'MCH'. Le système pastoral sédentaire du sud-est du Nigéria fonctionne à un niveau commercial très bas. Il y avait des differences significatives (P <0.05) dans certaines des entités biologiques telles que le poids vif à 12 et 24 mois, qui étaient meilleures pendant la saison des pluies que pendant la saison sèche. La gestion des étables était relativement meilleure que la gestion des pâturages sur le terrain. Les valeurs simulées étaient plus élevées que les valeurs réelles dans certaines des entités biologiques, mais cadraient avec la gestion des pâturages sur le terrain et des stalles. L'efficacité de la production de bétail / fourrage dans le système sédentaire était très faible avec 13.02, 15.32 et 17.35 pour cent respectivement pour le modèle de gestion et de simulation sur pâturage au champ, en stabulation. Les valeurs de la biomasse et de la productivité du troupeau deMuturu sous le système pastoral sédentaire dans la région du Sud-Est étaient très faibles avec 25.00 et 33.33pour centrespectivement pour la gestion des pâturages au champ et des stalles.

Abstract:
This study evaluated the growth performance of weaner rabbits fed diets containing sundried soybean milk residue meal (SSMR) at five levels of inclusion. Forty weaner rabbit with an average initial weight of 520±1.04g arranged in a completely randomized design (CRD) were used. SSMR was used at 0, 25, 50, 75 and 100% levels to replace soya bean meal. The result of the growth performance showed progressive increase in parameter evaluated as the level of SSMR increases in the diets. Rabbits fed (100% SSMR) recorded significant higher final body weight 1351.73g which was similar to rabbits fed 25, 50 and 75% SSMR while those on T1 (0% SSMR) had the least value of 1194.50g. However, carcass characteristics and internal organ weights measurements were also not influenced by the treatment diets. It was therefore concluded that 100% SSMR can be used in compounding weaner rabbits without deleterious effect on growth performance, carcass characteristics and internal organ weights. Cette étude a évalué le rendement de croissance des lapins sevrés nourris selon des régimes contenant des résidus de lait de soja séchés au soleil (RSSS) à cinq niveaux d'inclusion. Quarante lapins sevrés d'un poids initial moyen de 520±1,04 g disposés dans un modèle complètement randomisé (CRD) ont été utilisés. SSMR a été employé aux niveaux de 0, 25, 50, 75 et 100% pour remplacer le repas de haricot de soja. Le résultat de la performance de croissance a montré l'augmentation progressive du paramètre évalué comme le niveau des augmentations de SSMR dans les régimes. Les lapins nourris (100% SSMR) ont enregistré un poids corporel final plus élevé significatif 1351.73g qui était similaire aux lapins nourris 25, 50 et 75% SSMR tandis que ceux sur T1 (0% SSMR) avaient la valeur la moins élevée de 1194.50g. Cependant, les caractéristiques de carcasse et les mesures internes de poids d'organe n'ont pas non plus été influencées par les régimes de traitement. Il a donc été conclu que 100% SSMR peut être utilisé dans la composition des lapins sevrés sans aucun effet sur la performance de croissance, les caractéristiques de la carcasse et le poids interne des organes.

Abstract:
Organ characteristics of male growing male pigs fed low crude protein and low energy diets supplemented with multi-enzyme were determined using 36 hybrid (Landrace x Large white) male pigs of 8-10 weeks old. Two metabolizable energy (3000 and 2600 Kcal ME/kg) and three crude protein levels (14, 16 and 18 % CP) were used to formulate six dietary treatments; T1: control (3000 Kcal ME/kg; 18 % CP), T2 (3000 Kcal ME/Kg; 16 % CP), T3 (3000 Kcal ME/kg; 14 % CP), T4 (2600 Kcal ME/kg; 18 % CP), T5 (2600 Kcal ME/kg; 16 % CP) and T6 (2600 Kcal ME/kg; 14 % CP). The enzyme was added to all the treatments at 1g/kg diet except the control. The treatments were replicated three times with two pigs per replicate. The experiment was a 2 x 3 factorial. The pigs were starved for 12 hours but allowed access to drinking water, stunned and bled completely. It was cut open though the thorax region along the underline to the abdomen, exposing the entire internal organs and GIT contents. The heart, lungs, liver, kidneys, spleen and other internal organs were examined, carefully removed and weighed with a sensitive electronic kitchen scale, model SF-400. Higher (P <0.05) live weight (33500.00g), with lower (P <0.05) mean values for heart and viscera were recorded in male growing pigs fed T4. Male growing pigs fed with T3 and T6 had lower (P<0.05) live weight (12200.00g and 11500.00g), and higher (P<0.05) relative internal organs. Male growing pigs fed 14 % CP diets (T3 and T6) with their corresponding metabolizable energy levels (3000kcal and 2600kcal) recorded higher (P<0.05) heart and viscera's values. Keeping growing (male) pigs on low crude protein diets (14 %) supplemented with multi-enzyme, irrespective of the energy levels, did not improve live weight but increased relative organ weight. Les caractéristiques des organes de porcs mâles en croissance nourris à faible en protéines brutes et en énergie mais plutôt supplémentée en multi-enzymes ont été déterminées en utilisant 36 porcs mâles hybrides (Landrace x Large white) âgés de 8 à 10 semaines. Deux énergies métabolisables (3000 et 2600 Kcal ME / kg) et trois niveaux de protéines brutes (14, 16 et 18% CP) ont été utilisés pour formuler six traitements diététiques ; T1 : contrôle (3000 Kcal ME / kg ; 18% CP), T2 (3000 Kcal ME / Kg ; 16% CP), T3 (3000 Kcal ME / kg ; 14% CP), T4 (2600 Kcal ME / kg ; 18 % CP), T5 (2600 Kcal ME / kg ; 16% CP) et T6 (2600 Kcal ME / kg ; 14% CP). L'enzyme a été ajoutée à tous les traitements à raison de 1 g / kg de régime sauf le témoin. Les traitements ont été répliqués trois fois avec deux porcs par réplica. L'expérience était une factorielle 2 x 3. Les porcs ont été affamés pendant 12 heures mais ont eu accès à l'eau potable, étourdis et saignaient complètement. Il a été ouvert à travers la région du thorax le long du trait de soulignement jusqu'à l'abdomen, exposant l'ensemble des organes internes et le contenu du 'GIT'. Le cœur, les poumons, le foie, les reins, la rate et d'autres organes internes ont été examinés, soigneusement prélevés et pesés avec une balance de cuisine électronique sensible, modèle SF-400. Un poids vif plus élevé (P <0,05) (33500,00 g), avec des valeurs moyennes plus faibles (P <0,05) pour le cœur et les viscères ont été enregistrés chez des porcs en croissance mâles nourris au T4. Les porcs mâles en croissance nourris avec T3 et T6 avaient des organes internes relatifs inférieurs (P <0,05) (12 200,00 g et 11500,00 g) et supérieurs (P <0,05). Les porcs mâles en croissance nourris avec 14% de régimes 'CP' (T3 et T6) avec leurs niveaux d'énergie métabolisables correspondants (3000 kcal et 2600 kcal) ont enregistré des valeurs cardiaques et viscérales plus élevées (P <0,05). Le fait de garder les porcs en croissance (mâles) avec des régimes pauvres en protéines brutes (14%) supplémentés en multi-enzymes, quels que soient les niveaux d'énergie, n'a pas amélioré le poids vif mais augmenté le poids relatif des organes

Abstract:
A total of 144, one-day-old Arbor Acre chicks were used to investigate the effect of feeding diets containing cowpea milling waste and plantain peel meal mixture (CMWPPM) on the growth performance, nutrients digestibility and economy of feed conversion of broiler chickens. The birds were randomly allotted to four dietary treatments in a completely randomized design model, and consisted of 0, 10, 20 and 30 % dietary inclusion levels of CMWPPM. Each treatment was replicated three times with 12 chicks per replicate, making a total of 36 chicks per treatment. The experiment lasted for seven weeks. Nutrients digestibility studies were carried out at the 3rd and 7th week of the experiment using speciallydesigned metabolism cages. Results showed that at the starter phase, birds on CMWPPM 0% had significantly (P<0.05) higher feed intake, while birds on CMMPPM 20 % had significantly (P<0.05) lower feed intake than birds on the other treatments. The cost of feed and total cost of feed intake were significantly (P<0.05) higher for CMWPPM 30 % and significantly lower for CMWPPM 20 % than for the other treatments; while feed cost per kg weight gain had no significant difference across the treatments. At the finisher phase, there were no significant differences in all the growth performance parameters measured across the treatment groups. However, total cost of feed intake was significantly (P<0.05) higher for CMWPPM 10 % and significantly (P<0.05) lower for CMWPPM 20 %. The feed cost per kg weight gain was significantly (P<0.05) higher for CMWPPM 10 % and significantly (P<0.05) lower for CMWPPM 20 % and 30 % diets. Results of nutrients digestibility at the starter phase show that though dry matter, crude protein, crude fibre and nitrogen free extract digestibility were significantly (P<0.05) different across the treatments, there were no significant (P>0.05) difference in the overall total digestible nutrient across the diets. For the finisher phase, as the level of CMWPPM increased in the diets, the CP, CF, ash, lipid, NFE and TDN decreased across the treatments Therefore, it is concluded that the inclusion level of CMWPPM in the diet of broiler chickens should not exceed 20 % for optimum economy of feed conversion at the finisher phase; whereas birds can be fed diets containing 30 % dietary inclusion level of CMWPPM with good economy of feed conversion at the starter phase. Un total de 144 poussins de 'Arbor Acre' âgés d'un jour a été utilisés pour étudier l'effet des régimes alimentaires contenant des déchets de 'cowpea' et du mélange de repas defarine d'écorce de 'plantain'. (Le 'CMWPPM') sur les performances de croissance, la digestibilité des nutriments et l'économie de la conversion alimentaire des poulets de chair. Les oiseaux ont été attribués au hasard à quatre traitements diététiques dans un modèle de conception complètement aléatoire, et consistaient en des niveaux d'inclusion alimentaire de 0, 10, 20 et 30% de 'CMWPPM'. Chaque traitement a été répété trois fois avec 12 poussins par répétition, soit un total de 36 poussins par traitement. L'expérience a duré sept semaines. Des études de digestibilité des nutriments ont été réalisées à la 3ème et 7ème semaine de l'expérience en utilisant des cages de métabolisme spécialement conçues. Les résultats ont montré qu'à la phase de démarrage, les oiseaux sous 'CMWPPM' 0% avaient une ingestion alimentaire significativement (P <0,05) plus élevée, tandis que les oiseaux sous 'CMMPPM' 20% avaient une ingestion alimentaire significativement (P <0,05) inférieure à celle des oiseaux sur les autres traitements. Le coût de l'alimentation et le coût total de la prise alimentaire étaient significativement (P <0,05) plus élevés pour CMWPPM 30% et significativement plus faibles pour CMWPPM 20% que pour les autres traitements ; tandis que le coût de l'alimentation par kg de gain de poids n'avait pas de différence significative entre les traitements. Lors de la phase de finition, il n'y avait pas de différences significatives dans tous les paramètres de performance de croissance mesurés dans les groupes de traitement. Cependant, le coût total de l'ingestion alimentaire était significativement (P <0,05) plus élevé pour CMWPPM 10% et significativement (P <0,05) inférieur pour CMWPPM 20%. Le coût de l'alimentation par kg de gain de poids était significativement (P <0,05) plus élevé pour le CMWPPM 10% et significativement (P <0,05) inférieur pour les régimes CMWPPM 20% et 30%. Les résultats de la digestibilité des nutriments à la phase de démarrage montrent que bien que la digestibilité de la matière sèche, des protéines brutes, des fibres brutes et de l'extrait sans azote soient significativement différentes (P <0,05) d'un traitement à l'autre, il n'y avait pas de différence significative (P> 0,05) dans le total de nutriments digestibles à travers les régimes. Pour la phase de finition, au fur et à mesure que le niveau de 'CMWPPM' augmentait dans les régimes alimentaires, le 'CP', les 'FC', les cendres, les lipides, l'NFE et le TDN diminuaient au fil des traitements. Par conséquent, il est conclu que le niveau d'inclusion de 'CMWPPM' dans l'alimentation des poulets de chair dépasse 20% pour une économie optimale de la conversion des aliments lors de la phase de finition ; tandis que les oiseaux peuvent être nourris avec des aliments contenant 30% de taux d'inclusion alimentaire de 'CMWPPM' avec une bonne économie de conversion alimentaire lors de la phase de démarrage.

Abstract:
La thèse étudie plusieurs problématiques centrales et actuelles de la finance moderne : la rationalité limitée des agents et leurs biais comportementaux vis-à-vis des valeurs nominales,le problème de la juste évaluation du prix des actions, la refonte du paysage de l'industrie post-négociation en Europe suite à l'introduction du projet de l'Euro système Target-2 Securities, ainsi que les modèles de défaut et les méthodes d’estimation des cycles de défaut pour un secteur donné. Les techniques employées sont variées: enquêtes sur données individuelles, économétrie, théorie des jeux, théorie des graphes, simulations de Monte-Carlo,chaînes de Markov cachées. Concernant l’illusion monétaire, les résultats confirment la robustesse des résultats d’études précédentes tout en dévoilant de nouvelles perspectives de recherche, par exemple tenter d’expliquer la disparité des réponses selon les caractéristiques individuelles des répondants,en particulier leur formation universitaire. L’étude du modèle de la Fed montre que la relation de long terme entre taux nominal des obligations d’Etat et rendement des actions n’est ni robuste, ni utile à la prédiction sur des horizons temporels réduits. L’étude sur Target 2 Securities a été confirmée par les faits. Enfin, le modèle d’estimation des défauts à partir de chaînes de Markov cachées fait preuve de bonnes performances dans un contexte européen, malgré la relative rareté des données pour sa calibration
The thesis studies various themes that are central to modern finance : economic agents rationality and behavioural biases with respect to nominal values, the problem of asset fundamental valuation, the changing landscape of the European post-trade industry catalysed by the Eurosystem project Target 2 Securities, and models of defaults and methods to estimate defaults cycles for a given sector. Techniques employed vary: studies on individual data,econometrics, game theory, graph theory, Monte-Carlo simulations and hidden Markov chains. Concerning monetary illusion, results confirm those of previous study while emphasizing new areas for investigation concerning the interplay of individual characteristics, such as university education, and money illusion. The study of the Fed model shows that the long term relationship assumed between nominal government bond yield and dividend yield is neither robust, nor useful for reduced time horizons. The default model based on hidden Markov chains estimation gives satisfactory results in a European context, and this besides the relative scarcity of data used for its calibration

Thesis (MSc. (Animal breeding and genetics )) --University of Limpopo, 2006
The objective of this study was to estimate genetic parameters for weekly body weight of feed intake of individually fed beef bulls at centralized testing stations in South Africa using random regression models (RRM). The model for cumulative feed intake included the fixed linear regression on third order orthogonal Legendre polynomials of the actual days on test (7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77 and 84 day) for starting age group and contemporary group effects. Random regressions on third order orthogonal Legendre polynomials were included for the additive genetic effect of the animal and the additional random effect of weaning-herd-year (WHY) and on fourth order for the additional random permanent environmental effect of the animal. The model for body weights included the fixed linear regression on fourth order orthogonal Legendre polynomials of the actual days on test for starting age group and contemporary group effects. Random regressions on fourth order orthogonal Legendre polynomials were included for additive genetic effects and additional uncorrelated random effects of the WHY and the permanent environment. The residual effects for both traits were assumed to be independently distributed with heterogeneous variance for each measurement period. Variance ratios for additive genetic, permanent environment and WHY for cumulative feed intake at different days on test ranged from 0.07 to 0.10, 0.53 to 0.77 and 0.14 to 0.37, respectively. Variance ratios for additive genetic, permanent environment and WHY for weekly body weights at different test days ranged from 0.26 to 0.29, 0.37 to 0.43 and 0.26 to 0.34, respectively. Estimates of genetic correlation among the same trait (body weight or feed intake) measured at different test days were generally high (>0.80) for any give test pair. The WHY had a significant contribution in variation of performance of bulls on test, despite the 28-day adjustment period. RRM provided the opportunity to study changes in genetic variability within the studied traits over time. Random Regression Models could be used in the National Genetic Evaluation of beef bulls at central performance testing stations in South Africa.

Abstract:
This thesis will be focusing on studies about the hyperelastic material method and how to best implement it in a FEA model. It will look more specific at the Mooney-Rivlin method, but also have a shorter explanation about the different methods. This is due to problems Roxtec has today about simulating rubber takes long time, are instable and unfortunately not completely trustworthy, therefore a deep study about the hyperelastic material method were chosen to try and address these issuers. The Mooney-Rivlin method (which is a part of the hyperelastic material method) is reliant on a few constant to represent the material, how to obtain these constants numerical and later implement these is suggested in this thesis as well. The results is the methodology needed to obtain constants for Mooney-Rivlin and later how to implement these in FEA software. In this thesis the material Roxylon has been studied and given suggestion on these constants as well as an implementation of the given material.

Abstract:
Dans la cavité buccale, la santé parodontale repose sur un équilibre entre la communauté bactérienne sous-gingivale et la fonction immunitaire de l’hôte, toutes deux compatibles avec un état sain. Le modèle pathophysiologique actuel de la parodontite chronique montre un cercle vicieux entre un microbiote dysbiotique et une dérégulation de la réponse inflammatoire. Alors qu’un nombre croissant d’associations entre maladie parodontale et pathologie systémique sont rapportées, ce travail décrit comment une maladie génétique de surcharge en fer — l’hémochromatose héréditaire liée au gène HFE — est susceptible d’influencer l’équilibre hôte–microbiote au sein du sillon sous-gingival. Les études transversales, clinique et microbiologique, que nous avons menées, ont ainsi montré un impact du coefficient de saturation de la transferrine sur la sévérité de la parodontite, probablement en lien avec la sélection d’espèces pathogènes pour le parodonte. Cependant, l’analyse morphométrique du modèle murin de l’hémochromatose héréditaire Hfe(–/–) a révélé des altérations de la micro-architecture de l’os alvéolaire mandibulaire, suggérant un dérèglement du remodelage osseux. Un croisement entre deux modèles animaux, parodontite induite par Porphyromonas gingivalis et Hfe(–/–), a donc été mis en œuvre, afin d’explorer les mécanismes de cette association entre excès de fer, dysbiose bactérienne et parodontite
In the oral cavity, periodontal health relies on a balance between the subgingival bacterial community and the host’s immune function. The current pathophysiological model of chronic periodontitis shows a negative feedback loop that implies a dysbiotic microbiota and a dysregulation of the inflammatory response. As an increasing number of associations between the periodontal disease and systemic conditions are reported, this work describes how a genetic iron overload disease — HFE-related hereditary haemochromatosis — is likely to influence the host–microbiota interactions within the subgingival sulcus. We conducted clinical and microbiological cross-sectional studies, that showed transferrin saturation coefficient having an impact on the severity of periodontitis, probably related to the promotion of periodontal pathogenic species. However, morphometric analysis of the murine model for hereditary haemochromatosis Hfe(–/–) revealed alterations in the mandibular alveolar bone micro-architecture, suggesting a disruption of bone remodeling. A mixed animal model, with Porphyromonas gingivalis-induced periodontitis and Hfe(–/–) mice, was therefore performed, in order to explore the underlying mechanisms of the relationships between iron excess, bacterial dysbiosis, and periodontitis

Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2005
Fennentation is the process that results in the fonnation ofalcohol or organic acids on the basis of growth of bacteria, moulds or fungi on different nutritional media (Ahmed et al., 1982). Fennentation process have three modes of operation i.e. batch, fed-batch and continuous ones. The process that interests a lot of control engineers is the fed-batch fennentation process (Johnson, 1989). The Fed-batch process for the production ofyeast is considered in the study. The fennentation is based on the Saccharomyces cerevisiae yeast. It grows in both aerobic and anaerobic environmental conditions with maximum product in the aerobic conditions, also at high concentration of glucose (Njodzi, 200I). Complexity of fed-batch fennentation process, non-linearity, time varying characteristics, application of conventional analogue controllers provides poor control due to problems in tuning individual loops and the process characteristics. The problem for control of the fed-batch process for the production of yeast is further complicated by the lack of on-line sensors, lack ofadequate models as a result ofpoorly understood dynamics. The lack of on-line sensors results in the impossibility oftuning the analogue controllers in real time. The process for propagation of yeast in aerobic conditions is considered in the dissertation. The experiments are conducted at the University of Cape Town (DCT), Department of Chemical Engineering with a bioreactor and bio-controller combined in a Biostat ® C lab scale plant (H. Braun Biotech International, 1996). The bio-controller has built in Pill controller loops for control variables, with the ability to adjust the controller parameters i.e. P, D and I through the serial interface (SeidIer, 1996).

The objective of this analysis is to develop econometric models for forecasting fed cattle basis as well as compare these models with historic averaging methods of forecasting basis popular in existing literature. The econometric analysis also aims to identify important determinants of fed cattle basis. Both monthly and weekly models were assessed with data provided by the Livestock Marketing Information Center. All models analyzed the three regions of Nebraska, Kansas, and Texas. Monthly historic average approaches utilized historic fed cattle futures and fed cattle cash price series from January of 1995 through December of 2010. Weekly historic average approaches utilized historic fed cattle futures and fed cattle cash prices series from June of 2001 through December 2010. Data collected post mandatory price reporting implementation in 2001 was used in all econometric models. Overall lags of fed cattle basis, the spread between the nearby live cattle futures contract and the next deferred futures contract, and seasonality regularly proved to explain much of the variation in fed cattle basis in the econometric modeling. Multiple historic average based models were examined on both monthly and weekly frequencies. Once all competing models were estimated in-sample, out-of sample testing was conducted. The forecasting errors of all weekly models were compared to determine which methods prove to be dominant forecasters of fed cattle basis. This testing suggests historic averaging methods outperform the alternate econometric models in out-of-sample work. The econometric models helped to reveal some of the important factors determining fed cattle basis, however lags in collecting data on these factors may inhibit the forecaster’s ability to use these techniques in real time. One interesting revelation in regards to historic averages is the potential of Olympic averages as forecasters. These methods have not been explored in previous academic literature but tend to perform quite well in comparison with other methods explored.

Abstract:
This thesis evaluates the application of Reynolds equation in calculating fluid film forces (FFFs) in circumferential groove journal bearings (CGJBs) with both balanced and unbalanced rotors. The existing rig was fabricated at UNSW for that purpose. Unfortunately the rig was unsuitable because it was unstable at speeds as low as 500 rpm. This occurred because, when designing the rig, the traditional ??-film cavitation boundary model (CBM) was used. Consequently a modified cavitation boundary model (MCBM) was proposed which correctly predicted the instability threshold of the rig. Using the MCBM, new bearings were installed and the modified rig was stable in the required speed range up to 2400 rpm. Two existing computer programs to calculate bearing stiffness and damping coefficients and FFFs were modified for the purposes of this study. In addition, only dynamic components (AC components) of experimental FFFs could be measured accurately. The vertical mean value (DC component) of experimental FFF was approximated to the vertical reaction force and the horizontal DC component of experimental FFF was approximated to zero at each bearing. This thesis concludes that the numerical solution of Reynolds equation to calculate DC components of FFFs in a CGJB is valid with a proper selection of CBM. The agreement of AC components of the FFFs were good with a balanced rotor, but were poor with an unbalanced rotor. The modified CBM is more accurate than the existing ??-film CBMs. The cavity region is important to obtain accurate numerical results and depends on test conditions, bearing dimensions, etc. To design for critical speeds, cavitation pressure could be either oil vapour pressure or atmospheric pressure; however, to design for stability, cavitation pressure should be oil vapour pressure, or even much lower. Two halves of a CGJB carried different loads because of misalignment and different clearances. In addition, reducing length and increasing clearance significantly increased the stability of the rig. Finally, to obtain perfect agreement between numerical and experimental FFFs, short bearings and a smaller clearance ratio are strongly recommended. A special design to measure cavitation pressure is suggested.

Neue additive Fertigungsverfahren erzeugen hochkomplexe Strukturen deren strukturmechanische Eigenschaften bisher nicht vorhersagbar waren. Mit einem neuen Ansatz wird ohne Vernetzung wie sie in der FEM benötigt wird, eine Simulation des strukturmechanischen Verhaltens möglich. Erste Untersuchungen an bisher unvorstellbar komplexen Modellen zeigen eine hervorragende Performance, die gerade im Umfeld von typischen Gitterstrukturen der 3D-Druckverfahren einsetzbar sind und darüber weit hinausgehen. In diesem Vortrag wird anhand von Beispielen der hohe Wirkungsgrad der Software External aufgezeigt, der so in der FEM nicht möglich ist.

Full text
Abstract:
Numerous extant studies are dedicated to enhancing the safety of active transportation modes, but very few studies are devoted to safety analysis surrounding transit stations, which serve as an important modal interface for pedestrians and bicyclists. This study bridges the gap by developing joint models based on the multivariate conditionally autoregressive (MCAR) priors with a distance-oriented neighboring weight matrix. For this purpose, transit-station-centered data in Los Angeles County were used for model development. Feature selection relying on both random forest and correlation analyses was employed, which leads to different covariate inputs to each of the two jointed models, resulting in increased model flexibility. Utilizing an Integrated Nested Laplace Approximation (INLA) algorithm and various evaluation criteria, the results demonstrate that models with a correlation effect between pedestrians and bicyclists perform much better than the models without such an effect. The joint models also aid in identifying significant covariates contributing to the safety of each of the two active transportation modes. The research results can furnish transportation professionals with additional insights to create safer access to transit and thus promote active transportation.
