<p dir="ltr">The United States government and Environmental Protection Agency have mandated that vehicles must meet 54.5 miles per gallon(<i>07/29/2011: President Obama Announces Historic 54.5 Mpg Fuel Efficiency Standard/Consumers Will Save $1.7 Trillion at the Pump, $8K per Vehicle by 2025</i>, n.d.). Faced with increased governmental regulations, manufacturers must find new ways to improve their internal combustion engines. Examining the various components of internal combustion engines, there is potential to optimize individual components for mass reduction and thus improving vehicle performance. Engine Components, specifically connecting rods, are essential to the operation of an engine. While connecting rod designs are highly refined, breakthroughs in additive manufacturing technology have given way to novel approaches in the optimization process. Autodesk Inc. has provided an innovative, generative design space to reduce design time and explore complex optimization. The generative design process provides engineers with unique designs while considering many parameters including material, load cases, and manufacturing processes. The study applied generative design structural load casing to a connecting rod of a single cylinder Ryobi engine to optimize for metal additive manufacturing. The generated outcomes were subjected to finite element analysis to determine their feasibility against a traditional drop forged or die cast design. The results compared three generated geometries against three common additive manufacturing materials in ANSYS Mechanical. The generated geometries were tested for equivalent (Von Mises) stress, equivalent strain, and total deformation. The study, using preliminary forces in a static situation, found that mass reductions of up to 19% were achievable while maintaining performance capabilities of the original design.</p>

Background: People living with advanced dementia in nursing homes often spend the majority of time alone, with little contact with anyone. The need to connect with others is a central part of a philosophy known as Person Centred Dementia Care. A significant body of literature demonstrates the effectiveness of a range of approaches that facilitate connections, yet, we know little about staff perspectives on what facilitates them to connect on a daily basis. Aim: To develop a Grounded Theory to explain what facilitates nursing home staff to connect with residents living with advanced dementia. Methods: Semi structured interviews were conducted with nursing home staff (n=21) and relatives (n=5) from seven nursing homes. Following Strauss and Corbin’s (1990, 1998) Interpretivist Grounded Theory methodology, data collection and analysis proceeded iteratively, and theoretical sampling was used to develop the emergent theory. Results: The Grounded Theory ‘making the most of time’ explains that most connections occurred during personal care. Interdependent contextual and individual factors facilitated staff to make the most of time. Effective leaders were described to create a caring culture in which informal leaders (experienced staff) acted as role models. Staff were then more likely to understand, accept and tolerate dementia, know connections were part of their role, get to know residents and express caring values. In the right physical environment, this then facilitated staff to make the most of time during personal care. Increased training and education from specialised dementia units and experiential knowledge from family engagement then supplement such contexts. Implications: Future research could empirically test the theory ‘making the most of time’

This thesis explores the use of domicilium as a criterion in choice of law and jurisdiction in South African law with special reference to private-law status. In this area of the law adherence to the status theory has, in the recent past, resulted in the use of domicile as an exclusive ratio jurisdictionis. This has impacted negatively on choice of law issues in status matters: since domicile constituted the sole jurisdictional criterion, little attention was devoted to choice of law. Even though the lex domicilii was, in actual fact, applied to choice of law issues concerning private-law status, it happened only as a result of the assumption of jurisdiction by the forum domicilii. With the emergence of alternative jurisdictional criteria, such as ordinary residence, choice of law issues will have to be addressed from a conflict of laws perspective, since the jurisdictional criteria will no longer ensure the application of the appropriate lex causae. In this regard recognition of the functional diversification of jurisdictional and conflicts connecting factors is crucial: different principles and policies underlie the fields of jurisdiction and choice of law and this must be borne in mind when a connecting factor is selected. In view of the prominence of domicilium as a connecting factor, problem areas in regard to the interpretation and ascertainment of domicile, especially the domicile of choice, is investigated within the context of the Domicile Act 3 of 1992 and with a view to future reform. It is submitted that the subjective animus requirement for the acquisition of a domicile of choice remains uncertain and undefined. Since domicile constitutes such an important connecting factor in issues pertaining to private-law status, as well as other non-status matters, it is essential that it should be readily and easily ascertainable. In this regard certain concrete proposals for future reform are advanced. Ultimately the domicile of an individual should indicate the community to which he/she truly belongs: only then will domicile constitute a conflicts connecting factor which satisfies the demands of conflicts justice. / Private Law / LL.

Au début du XXème siècle, Poincaré puis Birkhoff ont été amenés, lors de leur recherche sur le problème restreint des trois corps, à étudier les courbes invariantes par une transformation d’une surface préservant l’aire. Cinquante ans plus tard, les théorèmes KAM démontrent la persistance de courbes invariantes après perturbation en topologie de classe k plus grande ou égale à trois. On peut alors se demander ce que devient ce résultat en topologie de classe moins élevée. Par ailleurs, l’étude des dynamiques C1-génériques connaît de nombreux développements, grâce notamment au Connecting Lemma. Par exemple, Bonatti et Crovisier on démontré qu’un difféomorphisme C1-générique d’une telle surface possède un ensemble dense de points dont l’orbite sort de tout compact. Ces deux résultats permettent de penser qu’un difféomorphisme C1-générique d’une surface n’admet pas de courbes fermées simples invariantes. C’est ce que nous démontrons dans ce travail. On obtient assez facilement, en utilisant le Connecting Lemma ainsi que les propriétés topologiques de l’anneau, qu’un difféomorphisme C1-générique de l’anneau possède des points périodiques sur toute courbe fermée simple invariante. Cela se généralise à une surface quelconque en utilisant une famille dénombrable d’anneau constituant une base de voisinages d’une courbe fermée simple quelconque. La construction d’une telle famille d’anneaux est le principal résultat du premier chapitre. Il s’agit alors de supprimer les points périodiques sur les courbes invariantes. Dans un premier temps, nous nous inspirerons d’un argument qu’Herman utilise dans le cadre de courbes invariantes par les twists de l’anneau pour montrer que tous les points périodiques ne peuvent être hyperboliques. Ensuite, nous définissons une propriété, la propriété G, qui si elle est vérifiée par un difféomorphisme symplectique et l’un de ses points périodiques elliptiques, empêche que ce point périodique appartienne à une courbe invariante. En montrant que cette propriété est vérifiée par un difféomorphisme C1-générique et tous ses points périodiques elliptiques, nous obtenons le résultat souhaité. Dans le quatrième chapitre, nous nous employons à définir de façon rigoureuse la notion de fonction génératrice qui est l’outil classique pour perturber des difféomorphismes symplectiques / Poincaré and Birkhoff were led, during their research on the restricted problem of three bodies, to study invariant curves under an area preserving map of a surface. Fifty years later, theorems KAM show the persistance of invariant curves in topology Ck with k greater or equal to three. What becomes this result in topology class lower. Moreover, the study of C1-generic dynamics knows many developments particulary through the Connecting Lemma. For example, Bonatti and Crovisier showed a C1-generic symplectic diffeomorphism of a compact surface is transitive. What they have adapted with M.-C. Arnaud to a non compact surface : a C1-generic symplectic diffeomorphism of a non compact surface has a dense set of points whose orbit leaves every compacts. These two results suggest a such application has not an invariant simple closed curve. The proof of this result is the aim of this work. We obtain, using the Connecting Lemma, a C1-generic symplectic diffeomorphism has periodic points on all the invariant curves. Then, deleting the periodic points from the invariant curves is the challenge. At first, we use an argument that Herman used in the context of curves invariant by a twist of annulus, to show that all periodic points cannot be hyperbolic. Then, we define a property, the property G, which, if it is verified by a symplectic diffeomorphism and one of its periodic elliptic points, prevents this periodic point belongs to an invariant curve. By showing that property is verified by a C1-generic symplectic diffeomorphism, we obtain the desired result. In the fourth chapter, we explain how to pertube a symplectic diffeomorphism with generating functions

Csaba CSEH Engine Connecting Rod Analysis Including Bolts Influence DW, ITE, 2008, 75 pp, 88 fig. The aim of my diploma work is a stress analysis in the material of a connecting rod during a stationary engine regime. Dynamic forces from the connecting rod‘s motion and the forces acting on the bolts are included in the calculations. The whole stress analysis is based on a FEM designed application on a model, that was created in a CAD system package according to the real component.

This diploma thesis applies to the light-weight itself of a connecting rod of a mass-produced tractor-engine. As a one of the most important and first part of this task is creating a 3D simulation model of a connecting rod. The strenght calculation is following skip factor of the light-weight, the exact calculated dimension of relieve is providing by means of an engine imbalance including the connecting rod. The outcome data of research are instrumental to the new relieve and strengthen 3D design. The conclusion and ending point of the diploma thesis evaluate results.

Rapid environmental changes linked to human-induced increases in atmospheric greenhouse gas concentrations have been observed on a global scale over recent decades. Given the relative certainty of continued change across many earth systems, the information output from climate models is an essential resource for adaptation planning. But in the face of many known modeling deficiencies, how confident can we be in model projections of future climate? It stands to reason that a realistic simulation of the present climate is at least a necessary (but likely not sufficient) requirement for a model’s ability to realistically simulate the climate of the future. Here, I present the results of three studies that evaluate the 20th century performance of global climate models from phase 5 of the Coupled Model Intercomparison Project (CMIP5). The first study examines precipitation, geopotential height, and wind fields from 21 CMIP5 models to determine how well the North American monsoon system (NAMS) is simulated. Models that best capture large-scale circulation patterns at low levels usually have realistic representations of the NAMS, but even the best models poorly represent monsoon retreat. Difficulty in reproducing monsoon retreat results from an inaccurate representation of gradients in low-level geopotential height across the larger region, which causes an unrealistic flux of low-level moisture from the tropics into the NAMS region that extends well into the post-monsoon season. The second study examines the presence and severity of spurious Gibbs-type numerical oscillations across the CMIP5 suite of climate models. The oscillations can appear as unrealistic spatial waves near discontinuities or sharp gradients in global model fields (e.g., orography) and have been a known problem for decades. Multiple methods of oscillation reduction exist; consequently, the oscillations are presumed small in modern climate models and hence are rarely addressed in recent literature. Here we quantify the oscillations in 13 variables from 48 global climate models along a Pacific ocean transect near the Andes. Results show that 48% of nonspectral models and 95% of spectral models have at least one variable with oscillation amplitude as large as, or greater than, atmospheric interannual variability. The third study is an in-depth assessment model simulations of 20th century monthly minimum and maximum surface air temperature over eight US regions, using mean state, trend, and variability bias metrics. Transparent model performance information is provided in the form of model rankings for each bias type. A wide range in model skill is at the regional scale, but no strong relationships are seen between any of the three bias types or between 20th century bias and 21st century projected change. Using our model rankings, two smaller ensembles of models with better performance over the southwestern U.S. are selected, but they result in negligible differences from the all-model ensemble in the average 21st century projected temperature change and model spread. In other words, models of varied quality (and complexity) are projecting very similar changes in temperature, implying that the models are simulating warming for different physical reasons. Despite this result, we suggest that models with smaller 20th century biases have a greater likelihood of being more physically realistic and therefore, more confidence can be placed in their 21st century projections as compared to projections from models that have demonstrably poor skill over the observational period. This type of analysis is essential for responsibly informing climate resilience efforts.
