In aeromechanical design one of the major rules is to operate under High Cyclic Fatigue (HCF) margins and away from flutter. The level of dynamic excitations and risk of HCF can be estimated by performing forced response analyses from blade row interaction forces or Low Engine Order (LEO) excitation mechanisms. On the other hand, flutter stability prediction can be assessed by calculation of aerodynamic damping forces due to blade motion. In order to include these analyses as regular practices in an industrial aeromechanical design process, interaction between the fields of fluid and structural dynamics must be established in a rather simple yet accurate manner. Effects such as aerodynamic and structural mistuning should also be taken into account where parametric and probabilistic studies take an important role. The present work presents the development and validation of a numerical tool for aeromechanical design. The tool aims to integrate in a standard and simple manner regular aeromechanical analysis such as forced response analysis and aerodynamic damping analysis of bladed disks. Mistuning influence on forced response and aerodynamic damping is assessed by implementing existing model order reduction techniques in order to decrease the computational effort and assess results in an industrially applicable time frame.  The synthesis program solves the interaction of structure and fluid from existing Finite Element Modeling (FEM) and Computational Fluid Dynamics (CFD) solvers inputs by including a mapping program which establishes the fluid and structure mesh compatibility. Blade row interaction harmonic forces and/or blade motion aerodynamic damping forces are inputs from unsteady fluid dynamic solvers whereas the geometry, mass and stiffness matrices of a blade alone or bladed disk sector are inputs from finite element solvers. Structural and aerodynamic damping is also considered. Structural mistuning is assessed by importing different sectors and any combinations of the full disk model can be achieved by using Reduced Order Model (ROM) techniques. Aerodynamic mistuning data can also be imported and its effects on the forced response and stability assessed. The tool is developed in such a way to allow iterative analysis in a simple manner, being possible to realize aerodynamically and structurally coupled analyses of industrial bladed disks. A new method for performing aerodynamic coupled forced response and stability analyses considering the interaction of different mode families has also been implemented. The method is based on the determination of the aerodynamic matrices by means of least square approximations and is here referred as the Multimode Least Square (MLS) method. The present work includes the program description and its applicability is assessed on a high pressure ratio transonic compressor blade and on a simple blisk. / QC 20110324 / Turbopower / AROMA

Lithium ion (Li-ion) batteries have been identified as a promising solution to meet the increasing demands for alternative energy in electric vehicles (EVs) and hybrid electric vehicle (HEVs). This work describes experimental and numerical study of thermal management of battery module consisting of cylindrical Li-ion cells, with an emphasis on the use of active control to achieve optimal cooling performance with minimal parasitic power consumption. The major contribution from this work is the first experimental demonstration (based on our review of archival journal and conference literature) and the corresponding analysis of active thermal control of battery modules. The results suggest that the active control strategy, when combined with reciprocating cooling flow, can reduce the parasitic energy consumption and cooling flow amount substantially. Compared with results using passive control with unidirectional cooling flow, the parasitic energy consumption was reduced by about 80%. This contribution was achieved in three steps, which was detailed in this dissertation in chapters 2, 3, and 4, respectively. In the first step, an experimental facility and a corresponding CFD model were developed to capture the thermal behavior of multiple battery cells. Based on the experimental and CFD results, a reduced-order model (ROM) was then developed for active monitoring and control purposes. In the second step, the ROM was parameterized and an observer-based control strategy was developed to control the core temperature of battery cells. Finally, based on the experimental facility and the ROM model, the active control of a battery module was demonstrated. Each of these steps represents an important facet of the thermal management problem, and it is expected that the results and specifics documented in this dissertation lay the groundwork to facilitate further study. / Ph.

Bei einer altersgerechten Arbeitsgestaltung mittels digitaler Menschmodelle (DMM) sind die altersbedingten Veränderungen der menschlichen Leistungsfähigkeit zu berücksichtigen. Altersbedingte Veränderungen wie bspw. der Beweglichkeit sind aktuell nur rudimentär bei der virtuellen Arbeitsprozessgestaltung abbildbar. Deshalb wird im Beitrag ein Konzept zur Integration von Altersfaktoren in DMM vorgestellt. Dem User-Centered-Design Prozess folgend, werden die einzelnen Schritte zur Integration von Altersfaktoren am Beispiel der Beweglichkeit dargestellt. Dazu werden die erhobenen Nutzeranforderungen und die Darstellung der nutzerorientierten Konfiguration der Altersfaktoren im DMM dargestellt. Im Ergebnis wird gezeigt, wie altersbedingte Veränderungen der menschlichen Leistungsfähigkeit in DMM nutzer-orientiert eingebunden werden können. Dem Nutzer soll damit perspektivisch eine effektive und effiziente altersgerechte Gestaltung in DMM mittels akkurater, relevanter Daten sowie geeigneter Unterstützung ermöglicht werden.

The diploma thesis deals with the drug addiction issue, the circumstances that lead to drug addiction and most importantly the impact the drug addiction has on an individual. It also describes the behaviour of the drug addicted in different life situations and the impact of such behaviour; specifically the impact of behaviour of the drug addicted Romany on functioning of Romany families and communities. The aim of this thesis is to present drug-related issues of the Romany ethnic group, specific aspects of the behaviour of the drug addicted and the impact of such behaviour on their communities. Terminology related to the topic is defined and further described and drug addiction related issues of the Romany ethnic group are specified. As a part of the analysis there are semi-structured interviews which aim to describe, as authentically as possible, behaviour of the drug addicted Romany and to help people understand what kind of impact the Romany community perceive as the most urgent. Among the most important there are: the negative and condemning attitude of the older generation towards the drug addicted members; financial burden of the families of the drug addicted and prevailing negative attitude of the majority society towards the Romany as a whole, which is strengthened by the behaviour of the drug addicted and by higher rate of criminality among them.

The ability to kneel is an important function of the knee joint, as it is required for many daily activities, including religious practices, professional occupations and recreational pursuits. The inability to kneel following total knee arthroplasty (TKA) is frequently a source of disappointment. This work investigates patients' understanding of the term 'kneeling' and what proportion of patients can kneel before and after TKA, as well as identifying the factors that can affect the ability to kneel following TKA. The underlying hypothesis tested was: 'There are no differences between kneeling ability before and after TKA'. Kneeling ability after TKA may be affected by many factors, including patient-specific factors, the extent of wear on RPC (Retro patellar Cartilage), postoperative AKP (Anterior Knee Pain) and post-operative ROM (Range of Motion). Thus a consecutive series of TKA patients were assessed to test the afore-mentioned hypothesis. In particular, the thesis has examined: • Interpretation of kneeling and perceptions of kneeling ability after TKA. • The extent of wear on Retro Patellar Cartilage (RPC) and its correlation to kneeling ability. • Sensory changes in the knee after TKA. • Preoperative and Postoperative Anterior Knee Pain (AKP) assessment. • The reality of kneeling ability before and after TKA. • Postoperative ROM of the knee and its correlation to kneeling function. The advice offered by healthcare professionals may contribute to a low postoperative rate of kneeling. The patellofemoral joint plays an essential role in knee function and a person's kneeling ability, may be greatly affected by the performance of this joint. Firstly, this study analysed the responses of two samples of participants drawn from diverse cultural backgrounds (Christian and Muslim), it examined their primary interpretation of what kneeling constitutes, along with a subjective assessment of the importance of kneeling in their everyday lives. Secondly, it explored patients' perceptions of their kneeling ability after TKA, with a comparative analysis of their responses to the kneeling questionnaire specifically constructed by the author and also the question in relation to kneeling in the Oxford Knee Score (OKS). The third component investigated retro-patellar cartilage (RPC) morphology using intraoperative examination and standardised photography. Fourthly, a cohort of patients listed for TKAs was followed prospectively, in order to assess their kneeling ability prior to and following treatment, along with identifying the factors that could affect this function, i.e. knee pain, range of motion, sensory changes and sensitivity to pain on the anterior aspect of the knee as assessed with dolorimetry. Differences were detected in the subjective interpretation of the kneeling function, as well as its importance, for the two diverse cultures involved in this study. Pain, as opposed to poor range of movement, was identified as the main reason which led to kneeling difficulties. The majority of respondents reported that it was either extremely difficult or impossible to kneel on the operated knee. The high flexed position (required for prayer in certain cultures) was the most difficult position to achieve for most of the patients. Prior to surgery, 30 patients were seen during this period, 15 (50%) out of 30 consecutive patients were unable to kneel in any position whatsoever. Of those who could kneel to some degree, the most common posture that they could achieve was the upright kneeling position. Considerable variations were found to occur in patients' understanding of the term 'kneeling'. Consequently, this has significant implications for the design and interpretation of questions in relation to kneeling for diverse cultures, which are characterised by distinct lifestyles. The current patient-based selfV administered questionnaires, such as the OKS, although useful as a simple measure of overall knee function, were found to have limitations as an effective assessment tool in the measurement of kneeling function either before or after TKA and indicate that there is a need for a culturally appropriate questionnaire to assess kneeling function. Retro-patellar cartilage lesions were very prevalent in patients undergoing TKA. However, no significant correlation existed between the total amount of retro-patellar cartilage wear and the ability to kneel. Patients were more likely to be able to kneel if the cartilage of the superior facets of the patella were disease free (P=0.02). At the six months post-surgery stage, of the 14 consecutive patients, who could kneel pre-operatively 6 were able to kneel post-operatively. Of the 13 consecutive patients who were unable to kneel pre-operatively, all were unable to kneel post-operatively. Knee pain was the main reason attributed to this difficulty. However, no link was found to occur between sensory changes and kneeling function in the patients who participated in the study, after TKA performed via an anterior midline incision.
