Heap, Graham Stewart. "Geometric estimation of strains in car body panels." Thesis, Loughborough University, 1988. https://dspace.lboro.ac.uk/2134/32802.
Full textAbstract:
The thesis focuses on the manufacture of car body panels at Austin Rover and in particular the phenomenon of spring-back. After pressing of a shallow drawn panel its shape is often flatter than required. This loss of shape control corresponds to areas of small strains. The aim of the thesis is to describe the generation of a database of small strain information at discrete points on a drawn panel, which could be used in the numerical modelling of the drawing process.

Structures and material combinations, tailored for multiple purposes, are within the reach of vehicle manufacturers. Besides reducing the environmental impact of the transportation sector these multi-functional structures can reduce costs, such as development, manufacturing and maintenance, and at the same time offer improved comfort to the passengers. This thesis sets out to develop multi-functional design algorithms and evaluate concepts for future composite high speed train car bodies with the objective of optimising the amount of mass needed to fulfil all functions of the structure. In a first step complete composite car bodies were developed, optimised and evaluated based on global stiffness requirements and load cases. The knowledge gained in this step was used as requirements for the strength and stiffness of panels during the continued development of the multi-functional optimisation which, besides strength and stiffness, later also considers sound transmission, thermal insulation, geometric restrictions, manufacturability and fire safety. To be able to include fire safety in the analysis, a method for simulating the high temperature response of layered composite structures was needed, and developed. Significant weight reductions are proven when utilising carbon fibre in the load carrying structure of the vehicle, on component level as high as 60%. Structures can be made significantly thinner when using the algorithms developed in this thesis and wall thickness is reduced by 5-6 cm. Analysis carried out and extensive literature surveys also suggest significant cost savings in manufacturing, maintenance and use-phase, even thou the raw material cost can be significantly higher as compared to the conventional steel or aluminium alternatives. Results from drive cycle simulations showed that the benefit, with respect to reduced energy consumption, is in the range of 0.5-0.8% per reduced weight percentage, comparable to both automotive and air applications. The algorithms and methods established in this thesis can be directly applied for the development and analysis of future high speed train car bodies.QC 20130521

Full textAbstract:
This diploma thesis is focused on the matter of radiation heating, thermal comfort maintenance and setting optimal operation parameters for heating system equipped with radiation panels. The research section summarizes the effects most important for thermal comfort, methods of its determination, heat exchange distribution between the human body and its environment, and technical possibilities of heating car interiors. The central points of this work are the simulation of car interiors heated with radiation panels and the evaluation of thermal comfort with a virtual mannequin. Thermal state was determined via the equivalent temperature and thermal comfort zones diagram (method by O.H. Nilsson). Forty-two simulated scenarios led us to conclude that thermal comfort is not possible to obtain with panels exuding a maximum temperature of 43 °C and the combination of several heat sources is required. Nevertheless radiation heating considerably contributes to energy savings without the loss of thermal comfort in assessed car.

Full textAbstract:
The sheet metal forming process basically involves the shaping of sheet metal of various thickness and material properties into the desired contours. This metal forming process has been extensively used by the automotive industry to manufacture both car panels and parts. Over the years numerous investigations have been conducted on various aspects of the manufacturing process with varied success. In recent years the requirements on the sheet metal forming industry have headed towards improved stability in the forming process while lowering environmental burdens. Therefore the overall aim of this research was to identify a technique for developing lubricant formulations that are insensitive to the sheet metal forming process.
Due to the expense of running experiments on production presses and to improve time efficiency of the process the evaluation procedure was required to be performed in a laboratory. Preliminary investigations in the friction/lubricant system identified several laboratory tests capable of measuring lubricant performance and their interaction with process variables. However, little was found on the correlation between laboratory tests and production performance of lubricants. Therefore the focus of the research switched to identifying links between the performance of lubricants in a production environment and laboratory tests. To reduce the influence of external parameters all significant process variables were identified and included in the correlation study to ensure that lubricant formulations could be desensitised to all significant variables.
The significant process variables were found to be sensitive to die position, for
instance: contact pressure, blank coating of the strips and surface roughness of the dies were found significant for the flat areas of the die while no variables affected friction when polished drawbeads were used. The next phase was to identify the interaction between the significant variables and the main lubricant ingredient groups. Only the fatty material ingredient group (responsible for the formation of boundary lubricant regimes) was found to significantly influence friction with no interaction between the ingredient groups. The influence of varying this ingredient group was then investigated in a production part and compared to laboratory results.
The correlation between production performance and laboratory tests was found to be test dependant. With both the Flat Face Friction test and the Drawbead Simulator unaffected by changes in the lubricant formulation, while the Flat Bottom Cup test showing similar results as the production trial. It is believed that the lack of correlation between the friction tests and the production performance of the lubricant is due to the absence of bulk plastic deformation of the strip. For this reason the Ohio State University (OSU) friction test was incorporated in the lubricant evaluation procedure along with a Flat Bottom Cup test.
Finally, it is strongly believed that if the lubricant evaluation procedure highlighted in this research is followed then lubricant formulations can be developed confidently in the laboratory.

Le Contrôle Non Destructif (CND) de matériaux composites multicouches pour des problèmes de qualité, viabilité, sécurité et disponibilité des systèmes qui impliquent des pièces fabriquées dans les industries aéronautiques et de l’automobile est devenu une tâche essentielle aujourd’hui. L'objectif visé par cette thèse est l’imagerie électromagnétique de structures complexes multicouches anisotropes, de plus en plus utilisées dans des applications, et encore source de sérieux défis à l'étape de leur modélisation et encore plus à l'étape souvent en enfance de leur imagerie. En utilisant une vaste gamme de fréquences, qui va des courants de Foucault jusqu’aux micro-ondes, il y a un fort besoin de rendre disponibles des procédures de modélisation et d'imagerie qui sont robustes, rapides, précises et utiles à la décision des utilisateurs finaux sur des défauts potentiels, tant donc en basse fréquence (BF) (matériaux conducteurs, type fibre de carbone) qu’en haute fréquence (HF) (matériaux diélectriques, type fibre de verre). De plus, il est important d'obtenir des résultats en des temps brefs. Cependant, cela nécessite la connaissance d’une réponse précise à des sources externes aux multicouches, en considérant les couches des composites comme non endommagées ou endommagées : on parle donc de solution du problème direct, avec le cas particulier de sources élémentaires conduisant aux dyades de Green (DGF). La modélisation et la simulation numérique du problème direct sont gérés principalement via une solution au premier ordre de la formulation intégrale de contraste de source impliquant le tenseur de dépolarisation des défauts, quand ceux-ci sont assez petits vis-à-vis de l’épaisseur de peau locale (cas BF) ou de la longueur d'onde locale (cas HF). La précision des DGF doit nécessairement être assurée alors, même si les sources se situent loin de l'origine, ce qui donne un spectre de dyades qui oscille très rapidement. La technique d'interpolation-intégration dite de Padua-Domínguez est ainsi introduite dans le but d'évaluer de façon efficace des intégrales fortement oscillantes.Néanmoins, les matériaux composites peuvent souffrir de divers défauts, lors du processus de fabrication ou pendant leurs utilisations. Vides d’air, cavités remplies de liquide, fissures, etc., peuvent affecter le fonctionnement correct des structures composites. Il est donc indispensable de pouvoir détecter la présence des défauts. Ici, l’insistance est sur la méthode bien connue d’imagerie dite MUltiple SIgnal Classification (MUSIC), qui est basée sur la décomposition en valeurs singulières (SVD) des DGF ; celle-ci est développée afin de localiser les positions de multiples petits défauts volumiques en interaction faible enfouis dans des milieux anisotropes uniaxiaux. Le principal inconvénient de la méthode MUSIC est cependant sa sensibilité par rapport au bruit. Par conséquent, des méthodes MUSIC avec une résolution améliorée et la Recursively Applied and Projected (RAP) MUSIC sont introduites afin de surmonter un tel inconvénient de l'algorithme standard et de fournir des résultats de qualité avec une meilleure résolution. De nombreuses simulations numériques illustrent ces investigationsNon-Destructive Testing/Evaluation (NdT/E) of multi-layered composite materials for problems of quality, viability, safety and availability of systems involving manufactured parts (in aeronautics and in automotive industry, as a good example) has become an interesting and challenging task nowadays. The focus of the PhD thesis is on the electromagnetic (EM) imaging of complex anisotropic multi-slab composite panels as increasingly encountered in applications, yet source of strong challenges at modeling stage and even more at often-in-infancy imaging stage. From eddy-currents to microwaves, there is a strong need to make available modeling and imaging procedures that are robust, fast, accurate and useful to potential end-users’ decision about potential defects both at low-frequency (LF) (conductive materials, carbon-fiber like) and high-frequency (HF) (dielectric materials, glass-fiber like). Moreover, it is important to get the results in close-to-real-time. However, this requires an accurate response to external sources of the multilayers, considering the layers which these composite structures are made of as undamaged or damaged. The modeling at forward stage is managed via a first-order solution involving the dyadic Green’s functions (DGF) of the layers along with the depolarization tensor of the assumed defects when they are small enough vis-à-vis the skin depth (LF case) or the wavelength (HF case). The accuracy of the DGF has to be ensured even if the sources lie far away from the origin, which yields a fast-oscillating spectrum of the dyads. The Padua-Domínguez interpolation-integration technique is introduced herein in order to evaluate in an effective fashion fast-oscillating integrals.Damages or disorders, which these composite structures may suffer from, are of many kinds. One could mention voids, fluid-filled cavities or uniaxial defects with obvious impacts on the electromagnetic and geometric parameters of the multilayers. That is, the task to make available to end-users imaging algorithms tailored to detect the presence of defects. The well-known standard MUltiple SIgnal Classification (MUSIC) algorithm, which is based on the Singular Value Decomposition (SVD) of such DGF, is here applied to localize the positions of small multiple defects with weak interaction embedded in anisotropic uniaxial media. The main drawback of MUSIC is its sensitivity with respect to the noise. Therefore, MUSIC with enhanced resolution and Recursively Applied and Projected (RAP) MUSIC are introduced to overcome such a drawback of the standard algorithm and to provide quality results with better resolution

Construction equipment such as wheel loaders and dumpers are constantly getting updated with new technology when it comes to performance and fuel consumption. But the interior in the cockpit has not been exposed to any dramatic changes for decades. A modernized cockpit gives the driver a more modern feel of driving a highly technological machine, while at the same time enables for personalization. This thesis work presents a new way of improving the look and feel for displaying relevant information and also relaying information to both the driver of the machine and spectators outside. It includes a way of rerouting CAN-bus signals from a construction machine and displaying it on a tablet. The core idea with the solution is to make it as modular as possible to further improve and be able to use it in any machine available at Volvo's disposal. With this in mind, any machine could use the same software, the same hardware and still be able to fully utilize all the features that have been implemented from the thesis work. The idea and implementational results are designed as partly embedded and partly towards user interface.

Full textAbstract:
The rapid growth in the use of non-cash payment instruments, specifically debit and credit cards, has become a prominent feature of modern economies. With an interest in the explanation of this phenomenon and differences in use across countries, we apply a model of payment instrument use to model the relationship between the dependent variables (total volume of card transactions, debit card transactions, and credit card transactions) and the five independent variables based on income, infrastructure, substitution, and institutional influences. We estimate the model and perform a regression analysis on a panel of 22 countries over the period 2009 to 2013. We find that crime, bank concentration, and income have positive relationship with the use of card instruments, while cash is found to be both a complement and substitute to card payments. The variable based on infrascture yields insignificant results. With the results, our purpose is to give greater insight into to the use of the card payments and the explanations for differences in use across countries.

This thesis examines the convergence in health care spending in euro area member countries during the period 1995-2010 and the influence of joining euro zone on convergence of health care expenditure. Panel data set covering 17 cross-sectional units (current eurozone member countries) over 15-years time period is examined using the classical approach to convergence. The analyses presented in this thesis provide evidence of sigma-convergence of HCE as a share of GDP. Conditions for sigma-convergence of HCE per capita are not satisfied. As for beta-convergence, the analysis of HCE as a share of GDP confirm the absolute convergence, conditional convergence did not occur. As for HCE per capita, absolute and conditional convergence hypotheses were affirmed. In both cases of absolute convergence, joining the euro area significantly supported convergence of HCE.

Full textAbstract:
Rollovers tend to be very severe crashes because of the energy required to roll a vehicle over unlike front and side crashes. This study is an effort towards reducing the severity of a rollover crash by strengthening the roof of a passenger car. The main focus of this thesis is to study the effect of reinforcing the roof of a car, in the event of a rollover. An Eglass/polypropylene isogrid composite panel, which is known for high specific energy absorption under impact, is used in reinforcing the roof of a ford Taurus car and the force-displacement response of the roof structure is observed in contrast to the same while without the roof reinforcement. The non-linear Finite Element Analysis (FEA) simulation of this rollover event is performed in LS DYNA computer code. The simulation setup is done in accordance with Federal Motor Vehicle Standard (FMVSS) No. 216, which is a static study of roof strength in the case of rollover accidents. A study of roof strength characteristics under dynamic loading, involving rollover forces and velocities, is also carried out. The simulation in the latter case involves dropping the car, inverted at a certain pitch and roll offset against gravity from a certain predetermined height onto a concrete surface. The results of the above simulations show that Isogrid composite panels are excellent reinforcements for a car roof, stiffening the roof and increasing its resistance to crush in a rollover accident. This study will help in recommending the use of isogrid panels in the design of car roofs with better roof crush characteristics.Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Mechanical Engineering

Full textAbstract:
A credit card as a banking product has a dual nature both as a convenient loan and a payment tool. Credit card profitability prediction is a complex problem because of the variety of the card holders' behaviour patterns, a fluctuating balance, and different sources of interest and transactional income. The state of a credit card account depends on the type of card usage and payments delinquency, and can be defined as inactive, transactor, revolver, delinquent, and default. The proposed credit cards profit prediction model consists of four stages: i) utilisation rate and interest rate income prediction, ii) non-interest rate income prediction, iii) account state prediction with conditional transition probabilities, and iv) the aggregation of the partial models into total income estimation. This thesis describes an approach to credit card account-level profitability prediction based on multistate and multistage conditional probabilities models with different types of income and compares methods for the most accurate predictions. We use application, behavioural, card state, and macroeconomic characteristics as predictors. This thesis contains nine chapters: Introduction, Literature Review, six chapters giving descriptions of the data, methodologies and discussions of the results of the empirical investigation, and Conclusion. Introduction gives the key points and main aims of the current research and describes the general schema of the total income prediction model. Literature Review proposes a systematic analysis of academic work on loan profit modelling and highlights the gaps in the application of profit scoring to credit cards income prediction. Chapter 3 describes the data sample and gives the overview of characteristics. Chapter 4 is dedicated to the prediction of the credit limit utilisation and contains the comparative analysis of the predictive accuracy of different regression models. We apply five methods such as i) linear regression, ii) fractional regression, iii) beta-regression, iv) beta-transformation, and v) weighted logistic regression with data binary transformation for utilisation rate prediction for one- and two-stage models. Chapters 5 and 6 are dedicated to modelling the transition probabilities between credit card states. Chapter 5 describes the general model setups, model building methodology such as transition probability prediction with conditional binary logistic, ordinal, and multinomial regressions, the data sample description, the univariate analysis of predictors. Chapter 6 discusses regression estimation results for all types of regression and a comparative analysis of the models. Chapter 7 describes an approach to the non-interest rate income prediction and contains a comparative analysis of panel data regression techniques such as pooled and four random effect methods. We consider two sources of non-interest income generation: i) interchange fees and foreign exchange fees from transactions via pointof- sales (POS) and ii) ATM fees from cash withdrawals. We compare the predictive accuracy of a one-stage approach, which means the usage of a single linear model for the income amount estimation, and a two-stage approach, which means that the income amount conditional on the probability of POS and ATM transaction. Chapter 8 aggregates the results from the partial models into a single model for total income estimation. We assume that a credit card account does not have a single particular state and a single behavioural type in the future, but has a chance to move to any of possible states. The income prediction model is selected according to these states, and the transition probabilities are used as weights for the particular interest rate and non-interest rate income prediction models. Conclusion highlights the contributions of this research. We propose an innovative methodological approach for credit card income prediction as a system of models, which considers the estimation of the income from different sources and then aggregates the income estimations weighted by the states transition probabilities. The results of comparative analysis of regression methods for: i) utilization rate of credit limit and ii) non-interest income prediction, iii) the use of panel data with pooled and random effect for profit scoring, and iv) account level non-binary target transition probabilities estimation for credit cards can be used as benchmarks for further research and fill the gaps of empirical investigations in the literature. The estimation of the transition probability between states at the account level helps to avoid the memorylessness property of the Markov Chains approach. We have investigated the significance of predictors for models of this type. The proposed modelling approach can be applied for the development of business strategies such as credit limit management, customer segmentation by the profitability and behavioural type.

Full textAbstract:
The transport sector is a major end-user of energy. As consumers are becoming aware and conscious of their environmental footprint making the enviromental footprint of automobile components one of the requirements in new product design development. The purpose of the study is to identify environmental impacts of a plastic panel. The main objective of the study is to perform an environmental life cycle assessment (E-LCA) of an existing panel regarding four scenarios with a nonbio-based plastic and a bio-based plastic. The first two scenarios have the same production and use phase, but different end-of-life treatments. The plastic in these scenarios is non-biobased. The last two scenarios have the same bio-based plastic and use phase, but different end-of-life-treatments. The first three scenarios have a surface material covering the plastic. The environmental impacts analyzed are global warming potential, acidification potential, eutrophication potential, photochemical ozone creation potential, primary energy demand and particulate matter. The analysis is carried out according to the ISO14040/44 with the four steps of LCA: 1) Goal and Scope Definition, 2) Inventory Analysis, 3) Impact Assessment, and 4) Interpretation. The functional unit of the anaysis is a plastic panel. The inventory was collected by literature, the LCA software GaBi, and the commissoner of the study. The environmental impact assessment was conducted in GaBi 8 with the method of CML2015, Primary Energy, and IMPACT2002+. A dominance and a contribution analyses were applied to identify the hotspots of the life cycle. The hotspot of the life cycle was identified to be the production phase. The main contributor within the scenarios was the plastic production, specifically the granulates and the fiber fillings. The bio-based plastic reduced the impacts compared to the non-bio-based in five out of six cases. However, the photochemical ozone creation potential for both plastics were the same. The bio-based plastic reduced the GWP 16%, AP by 1%, EP by less than 1%, and PED by 19%. If the surface cover in aluminum was removed, the GWP was reduced by 46%, AP by 35%, EP by29%, POCP by 36%, PED by 42%and PM by 40%. The transportation contributed most to impacts in the acidification potential, eutrophication potential, and particulate matter. The transportation’s impacts were greater in the bio-based plastic than the non-bio-based. The granulates of the plastic along with the injection molding are the main contributors due to usage of coal-based electricity for the injection molding and oil for the plastic production. The values used in the study are based on country averages which may differ depending on geographic location and its development as China is a country with a large area. The GWP is the highest value of the impacts analyzed, but even though the other are small fractions these may cause great damages. These damages can irritate eyes, damage lungs and destroy photosynthesis. By using recycled material for products instead of new materials, as done in the study, the impacts could be lower. As some previous studies agrees, the usage of bio-plastics lowers the environmental impact by a few percentages. The bioplastic is an environmentally sustainable option to the current plastic as the location of the panel is not sensitive to excessive heat.

Full textAbstract:
This study investigates the impact macroeconomic factors have on corporate capital structure in Sweden. We use a panel data analysis of unbalanced data for the sample period, 2005-2014. While previous research has shown that key factors internal to the firm are highly correlated with leverage, such as profitability, asset tangibility and firm size, we add external factors and test for economic growth, inflation, interest rates, corporate tax rates, and exchange rates. Our models do not present any substantial explanatory power for the relationship between the macroeconomic environment and different leverage ratios. This study finds some support for certain indicators, although not consistent across ratios.

Full textAbstract:
Airbags are a passive safety technology, required to function with zero failure rate. Advances in Computer Aided Engineering have allowed vehicle manufacturers to predict material and system behavior in the event of a crash. The sudden and rapid nature of a vehicle frontal crash, together with strict requirements put on safety make this a sensitive task. This thesis focuses on the front passenger airbag deployment and the instrument panel’s response. Various airbag modelling techniques are studied and presented in this document. This work is part of a larger-scale attempt to model a generic-sled that is physically representative of a real vehicle. Various component tests are to be performed in the sled environment, as opposed to a real vehicle, to save costs. Various modules are added to the sled once their behavior is verified by testing and in simulations. Software are advanced enough to identify location and magnitude of stress concentrations that develop during crash. LS-DYNA is used for explicit finite element simulations of the instrument panel (IP) in question with different airbag models. Verification has been achieved by design of experiment (DOE); with tests conducted to capture both the movements of the airbag housing and IP movements in response. These movements are broken down in various phases, facilitating implementation in the sled environment. Simplifications are made both to the computer models as well as the physical testing environment. The effects of these simplifications are quantified and discussed. Theoretical background is provided where fit while assumptions are justified wherever made. DYNAmore recommendations regarding costeffective calculations as well as result verification are followed. The obtained results show that the FE models replicate the real event with acceptable precision. The findings in this work can, by minor tweaks, be implemented on other IP models in the Volvo Cars range, leading to cost-saving solutions. This thesis provides the necessary information for sled implementations as well as future improvement suggestions.Krockkudde är en s.k. passiv säkerhetsteknik som krävs att fungera felfritt. Framsteg inom Computer Aided Engineering har tillåtit biltillverkare att förutsäga material och systembeteende i samband med krock. Den plötsliga karaktären av krock, tillsammans med höga säkerhetskrav, gör detta till en känslig uppgift. Denna avhandling fokuserar på passagerarsidans krockkudde och instrumentbrädans (IP) respons under uppblåsning. Olika metoder för modellering av krockkuddar har studerats och presenteras i detta dokument. Arbetet är en del av en större skala försök att modellera en generisk-släde som är fysiskt representativ av en riktig bil; där olika komponent-tester skall utföras för att minska kostnader. När olika modulers beteende verifieras läggs de till släden. Denna verifiering sker genom finita element (FE) simuleringar så väl som fysiska tester. FE mjukvara är idag tillräckligt avancerad för att identifiera samt visualisera spänningskoncentrationer som uppstår i en konstruktion vid krock. LS-DYNA används i detta arbete för explicita FE simuleringar av en Volvo XC90 IP, lastad med olika krockkudde-modeller. Modell verifiering har uppnåtts genom försöksplanering (DOE); med tester utförda för att fånga rörelser av IP så väl som krockkudde-behållaren. Dessa rörelser är sedan uppdelade i olika faser för enklare genomförande i släde miljön. Förenklingar och antaganden görs både till FE modeller och fysiska testmiljön. Effekter av dessa har kvantifierats och relevant teoretisk bakgrund har inkluderats. Dokumentet innehåller även diskussion kring val av mätutrustning samt förbättringsförslag för fortsatt arbete. DYNAmore rekommendationer gällande kostnadseffektiva beräkningar och verifiering av simulerings-resultat har följts. Under arbetet visade sig att FE modellerna kan återskapa händelsen med hög noggrannhet; dessa trotts svårigheter i modellering av plast material. Möjligtvis kan man, genom mindre modifieringar, relatera slutsatserna i detta arbete till olika IP modeller i företagets produktkatalog vilket förmodligen leder till ytterligare kostnadsbesparingar. Denna avhandling ger den information som behövs för genomföranden i den generiska miljön.

Full textAbstract:
Throughout the development of this report there will be a brief explanation of what the actual Aircraft Design Process is and in which stages the methodology that the authors are proposing will be implemented as well as the tools that will interact to produce this methodology.
The proposed tool will be the first part of a methodology that, according to the authors, by integrating separate tools that are currently used in different stages of the aeronautical design, will promote a decrease in the time frame for the initial stages of the design process.
The first part of the methodology above, that is proposed in this project, starts by creating a computer generated aircraft model and analyzing its basic aerodynamic characteristics “Lift Coefficient” and “Induced Drag Coefficient”, this step will be an alternative to statistical and empirical methods used in the industry, which require vast amount of data.
This task will be done in several steps, which will transfer the parametric aircraft model to an input file for the aerodynamic analysis program. To transfer the data a “translation” program has been developed that arranges the geometry and prepares the input file for analysis.
During the course of this report the reader will find references to existing aircrafts, such as the MD-11 or Airbus 310. However, these references are not intended to be an exact computer model of the mentioned airplanes. The authors are using this as reference so the reader can relate what he/she is seeing in this paper to existing aircrafts. By doing such comparison, the author intends to demonstrate that the Parametric Model that has been created possesses the capability to simulate to some extend the shape of existing aircrafts.
Finally from the results of this project it is concluded that the methodology in question is promising. Linking the two programs is possible and the aerodynamic characteristics of the models tested fall in the appropriate range. None the less the research must continue following the line that has been discussed in this report.

Full textAbstract:
The impact of the pharmacist in elderly patient healthcare management is developing. In our study, the interventions made by community pharmacists in the RESPECT study (Randomised Evaluation of Shared Prescribing for Elderly people in the Community over Time) were analysed and evaluated. In our study, the study sample was chosen according to specific criteria. The outcomes of these pharmacist interventions were measured by a clinical panel which scored and categorised each intervention into one of five categories. The study also investigated the percentage of interventions implemented or not implemented by GPs. In our study, initially 398 patients and of these 52 were excluded because their files did not contain the entry criteria information, leaving 346 patients who were identified with a mean (SD) of 8.9 (3.3) pharmaceutical care plans which contained mean (SD) 8.2(7.2) pharmaceutical care issues. Of these 43% were males and 57% were females with a mean (SD) age of 81(3.7) years. There were many missing data about drugs prescribed due to poor documentation by community pharmacists in the RESPECT study particularly at post study period (T5). The mean (SD) for all drugs prescribed was 35.9 (12.38) for each patient and for the whole study period including the post period (T5). In our study a total of 2879 individual pharmaceutical care issues were identified. A clinical panel judged that 43% of the interventions prevented harm, 31% improved the efficacy of management, 3% were detrimental to the patient's management plan, 12% only provided information and there was insufficient information to make a decision on the remaining 11%. For the classifications prevented harm to the patient and improve efficacy of management, the panel gave a score of 7 or more to 264 and 103 respectively which were classed as potential prevented hospital admissions. The outcome of 1628 could not be determined from the data and the pharmacist did not intervene on 361 occasions. Of the remaining 890 (30.9%) GPs accepted 715 and did not accept 175. The cost effectiveness of providing pharmaceutical care to older people by community pharmacists could be estimated (£620,000) by calculating reduction in expenditure of hospital admissions. In addition, there would be the possibility of reduced pressure on other NHS resources such as availability of hospital beds. The involvement of a clinical pharmacist in elderly patient health care, within the setting of a community pharmacy, provided positive healthcare outcomes and therefore should be encouraged in line with the new white paper for England "Building on strengths-delivering the future" (2008). The study emphasises the importance of revising the nature and period of postgraduate training for community pharmacists who are going to provide pharmaceutical care for elderly patients. This raises the possibility of specialised competency based postgraduate training for community pharmacists with a special interest in the care of older people (PhwSI). This would enable community pharmacists practising as generalists to become advanced practitioners in the specialist clinical area of older people and ensure a consistent level of service for elderly patients in line with government expectations.

For 25 years, I have worked in a high school education system, where for the final 2 years of schooling, teachers at each school write their own programs of work and write their own assessment items. They then mark and report on this assessment. There are no final public statewide exams, and as an outcome students right throughout the State are ranked for University entry. What follows is an exploration into the procedures that are put in place to ensure that each and every student is treated fairly and equitably. I will discuss the various levels of moderation that take place between schools, the processes that aid in keeping a level playing field for all concerned.

El primer capítulo utiliza una aproximación empírica homogénea en nueve países europeos, lo que hace posible relacionar las diferencias encontradas con diferencias en el contexto institucional. El segundo capítulo analiza el papel que juega el estado de salud en las transiciones hacia y fuera del empleo. Los resultados muestran que el estado de salud general afecta simétricamente las entradas y salidas del empleo, mientras que cambios en el estado de salud mental sólo influyen el riesgo de abandonar el empleo. El tercer capítulo examina los efectos de varios tipos de cuidados informales en el comportamiento laboral femenino. Los resultados sugieren que los costes de oportunidad laborales aparecen en aquellas mujeres que conviven con la persona dependiente, al mismo tiempo que los efectos negativos surgen cuando se proveen cuidados informales por un período superior al año.This thesis aims to contribute to the literature with an attempt to identify the causal effects of health on labour market outcomes in the working-age population. I analyse the effects of the onset of a health shock on the individuals' labour market outcomes, and also the effects of caregiving on female labour participation. The first chapter uses a homogeneous empirical framework to estimate the first set of effects on nine European countries, which allows me to relate the empirical estimates to differences in social security arrangements across these countries. The second chapter analyses the role of health in exits out of and entries into employment and the results show that general health affects symmetrically entries into and exits out of employment, but changes in mental health status influence only the hazard of non-employment for the stock sample of workers. The third chapter examines the effects of various types of informal care on female labour behaviour and the results suggest the existence of labour opportunity costs for those women who live with the dependent person they care for, and the negative effects appear when caregiving for more than a year.

Full textAbstract:
Although guidelines and minimal standards for the care and documentation of wounds in home health care settings in the United States are available, there is a lack of compliance among many home health care agencies (HHAs) with regard to the accuracy of wound documentation and care of wounds. Failure to follow guidelines for wound care according to Centers for Medicare and Medicaid Services and Home Health Outcome and Assessment Information System standards could result in loss of revenue for HHAs, improper treatment of wounds, and legal ramifications. The purpose of this doctoral project was to develop and validate a staff educational module on wounds and wound documentation for an HHA. Benner's from-novice-to-expert model was the conceptual framework for understanding nurses' matriculation. The practice-focused question focused on whether a wound staff educational module increased the home health care nurse's knowledge about wounds and wound documentation. A 5-level Likert scale was used by an expert panel to validate the staff educational module. Descriptive analysis was used to evaluate the data. The results of the survey supported implementing the educational module with recommendations (overall percentage 93% [4.4]). The findings of this project contribute to social change by increasing nurses' knowledge of wound care, improving the quality of wound care, increasing reimbursement and revenue, and decreasing the cost of care for wounds.

Full textAbstract:
L’automobile occupe une place fondamentale dans notre société, au point qu’on a pu parler de « civilisation de l’automobile ». En dépit des critiques qui lui sont régulièrement adressées, celle-ci n’a cessé de se renforcer, avec toujours davantage de voitures par adulte et une proportion croissante de déplacements effectués en voiture. Cependant, depuis le tournant du millénaire, on assiste à un retournement de tendance. Pour la première fois, la mobilité en voiture baisse dans les grandes agglomérations, tandis que la circulation automobile plafonne à l’échelle nationale. Cette évolution, du reste, n’est pas spécifique à la France mais s’observe dans l’ensemble des pays développés, une tendance parfois désignée sous le terme de « peak car (travel) ». Parmi les explications les plus convaincantes de ce retournement, figurent l’augmentation du prix du carburant, suivie de la récession de 2008. La volonté des ménages de maîtriser leurs budgets-temps de transport y contribue également, dans un contexte d’allongement des déplacements vers le travail et de dégradation des vitesses de déplacements. En outre, la diffusion de l’automobile se rapproche de la saturation. Si à long terme, la croissance du kilométrage moyen par adulte est indexée sur le taux de motorisation, cependant à moyen terme l’utilisation des véhicules fluctue en fonction du pouvoir d’achat énergétique, et un modèle basé sur ces deux variables suggère qu’on observerait une réaction normale à une augmentation exceptionnelle du prix du carburant. Les facteurs de croissance du taux de motorisation tiennent eux-mêmes principalement à la succession de générations de plus en plus motorisées, surtout chez les femmes, compte tenu d’un accès de plus en plus large au permis de conduire, à l’activité professionnelle, et d’une urbanisation de plus en plus diffuse, qui ont augmenté le besoin d’une seconde voiture. Pour modéliser l’auto-mobilité, on propose une approche emboîtée, individuelle et longitudinale, segmentée en fonction du genre. L’auto-mobilité peut en effet être vue au niveau individuel comme une succession de choix emboîtés, puisque la détention du permis conditionne l’accès à un véhicule personnel, de même que la motorisation conditionne l’usage d’un véhicule. L’avantage d’une approche longitudinale réside dans la possibilité de distinguer entre mesures d’hétérogénéité et de sensibilité, qui ne sont pas équivalentes. Pour chaque niveau de choix, l’approche est structurée autour d’une analyse de type âge-cohorte-période. Globalement, les taux de motorisation sont plus hétérogènes chez les femmes, un résultat qui est susceptible de recevoir une double interprétation, économique ou sociétale. On peut le voir en termes d’inégalités de genre. Mais il peut également s’interpréter comme le reflet d’un statut encore intermédiaire du second véhicule, dont l’opportunité serait davantage évaluée au regard des besoins et des contraintes réels du ménage. A l’inverse, l’usage des véhicules est à la fois plus élevé et plus hétérogène chez les hommes, compte tenu de la fonction collective du véhicule principal et des arbitrages internes aux ménages quant aux choix du lieu de résidence et des lieux de travail des conjoints. Pour finir, on estime à partir de modèles sur données de panel des effets marginaux et des élasticités par rapport au revenu, au prix du carburant et à la densité, qui sont ensuite comparées avec la littérature. Dans l’ensemble, les résultats sont cohérents avec l’analyse descriptive, ainsi qu’avec la littérature. Le modèle permet également de rendre compte du déclin tendanciel des élasticités, traduisant l’approche de la saturation. Pour finir, une évaluation a posteriori confirme l’opportunité d’une modélisation séquentielle, indiquant que les choix de motorisation sont indépendants des niveaux d’usage de la voitureCar ownership and use are a decisive part of our society, which was sometimes designed as the “civilization of the car”. Despite many critics, the car has become ever-more central in the modern way of life, with an ever-increasing number of cars per adult and proportion of trips realized by car. However, from the beginning of the millennium, there was a reversal in the trend towards ever-more car use. For the first time, the average number of daily trips realized by car has been falling down in French conurbations, and nationwide traffic by car is leveling off. This situation, nonetheless, is not specific to France but is common to many developed countries, and is often referred to as the “peak car (travel)”. The main explanations for such a downturn include rising fuel prices from the late 1990’s, followed by the recession in 2008, but also household’s willingness to control their travel time budgets, in a context of increasing commuting distances and reduced travel speeds. Besides, the diffusion of car ownership is approaching saturation. While on the long-run, average car travel per adult is indexed on motorization, mid-term fluctuations of average car use per vehicle are related to the energetic purchasing power, and a simple model based on these two variables is suggesting that the stagnation of car use from the 2000’s could be a reaction of a usual kind to an exceptional rise in fuel prices. The growth in motorization is itself principally caused by the follow-up of ever-more motorized generations, especially among women, given their increasing access to driving license, job participation and ever-more diffuse land use patterns, which have increased the need for a second car within households. In order to model auto-mobility, a nested, individual and longitudinal approach is implemented, segmented by gender. Auto-mobility can indeed be seen as a follow-up of nested choices, as driving license is necessary for holding a car, while access to a personal vehicle is itself required for car use. The advantage of a longitudinal approach consists in the ability to distinguish between measures of heterogeneity and sensitivity, which can be shown not to be equivalent. For every given level of choice, the approach is based on an age-cohort-period-type analysis. Motorization rates happen to be more heterogeneous among women, a result which is likely to receive an interpretation either of a social or economic nature. According to the first interpretation, it should be regarded as the illustration of gender inequalities. However, it could also be regarded as reflecting the still-intermediary status of the second vehicle, which opportunity is assessed depending upon household’s specific needs and constraints. On the contrary, car use is at the same time higher and more heterogeneous among men, given the collective function of the first vehicle and household’s internal trade-offs in residential and job choices. Finally, average partial effects and elasticities are estimated from panel data models, either with respect to income, fuel prices or density. Generally, results are consistent with the descriptive part, as with the literature. The model also rationally gives account of the decreasing trend for elasticities, which was often noticed in the literature and reflects the approach of saturation. As a conclusion, an a posteriori evaluation of the assumption of a sequential decision process is made, confirming that choices of motorization and car use are mutually independent

Full textAbstract:
The efficiency of physical capital accumulation plays a critical role for economic growth. This paper aims at examine if economic freedom promotes economic growth via physical capital accumulation. This is done by estimating a production function by replacing the inputs with institutional indices. The first input is GDP per capital growth rate which serve as a proxy for institutional aspects and the other input are the economic freedom indexes which will serve as proxies for physical capital accumulation. This is done by applying the augmented mean group (AMG) estimator that is designed for dealing with macro panel data analysis, including twenty developing countries where the economies have experienced a rapid growth, and the time period are between 1995 and 2017. The theoretical framework is based on the Solow growth model, institutional theory and marginal efficiency of capital (MEC). The results show that economic freedom promotes economic growth via physical capital accumulation where GDP per capital growth rate served as a proxy for institutional aspects and economic freedom indexes as proxies for physical capital accumulation. The results also show that the AMG estimator is the best fit for macro panel data analysis since it are designed for dealing with heterogeneity.

Full textAbstract:
Before vehicles were heavily relied on coal, fossil fuels and wind for power. Now, they are rapidly being replaced by electric vehicles and or plug-in hybrid electric cars. But these electric cars are still faced with the problem of energy availability because they rely on energy from biomass, hydro power and wind turbines for power generation. The abundance of solar radiation and its use as solar energy as a power source in driving these rapidly increasing electric cars is not only an important decision but also a necessary condition for eradication of environmental pollution. This study presents a model for charging electric cars from solar energy. Little focus on detailed technologies involved from solar energy capture to battery charging but our main focus is how to provide a modified charging parking lot in Karlskrona city-Sweden. With a surface area of 2850m2, we were able to choose 1STH-350-WH as the right PV modules. Based on the latitude of our design area, a computed 71 degrees angle positioning between solar panel and roof so as to maximise the surface area and optimise the solar irradiance gathering. Based on the power output of approximately116kW these PV modules generated, we further analysed and selected SDP 30KW inverter and Monocrystalline Silicon (1SolTech 1STH-350-WH (350W) solar modules. Also we provide different car charging method by choosing the SAE J1772 standard as one of specifications for dedicated vehicle charging and Clipper Creek HSC-40 as our option of charger. With the data of the generating solar energy every day, charging time, consuming power, we can estimate how many cars the system can handle to charge. Moreover, our system provides AC power from AC power network by general socket type F. We finally concluded that, our model for charging of electric car batteries was not only supportive but efficient in terms of extracting solar energy from sunlight to charge electric cars, thus making the region an eco-friendly place.

Full textAbstract:
The determinants of health expenditures have been studied extensively for the past 50 years and income has been seen as the major driver. The focus has rarely left developed countries which raises the question as to whether the same positive relationship exists in developing countries as well. The purpose of this thesis is to answer this question by conducting a fixed effect regression on a sample of 38 countries labelled as the least developed in the world by the United Nations with data stretching between 2000 to 2017. The results indicate a weaker relationship in the sample compared to estimates on developed countries. However, due to a lack of theoretical guidance on how health expenditures are determined and indications that omitted variable bias is present, the results do not provide definitive conclusions.

Full textAbstract:
In Healthy People 2010, mental health is listed as a major public health concern as evidenced by an alarming increase in the number of individuals who suffer from mental disorders. Mental disorders are a treatable public health condition. However, health disparities in the treatment of mental disorders are evident. The purpose of this study was to examine factors that affected health outcomes of persons with mental disorders. Two specific aims were addressed: Aim 1: to examine the relationships of population characteristics (predisposing factors and enabling resources), health behaviors (health services use and health practice); and health outcomes (physical health status and mental health status); Aim 2: to determine the differences in the usual source of care and health outcomes between individuals with self-reported mental disorders and individuals without mental disorders. This study was a secondary analysis of existing data collected from 2006 Medical Expenditure Panel Survey Household Component Consolidated file. A sample of U.S. civilian non-institutionalized adults (N=622) was grouped according to three self-reported health conditions: mental disorders (MD), physical illnesses (PI) and co-morbid mental disorders and physical illnesses (CM). This sample was predominantly male, White non-Hispanic and married; had a high school diploma, middle to high income, and private insurance; and preferred office-based clinics as the usual source of care, F(2,29)=5.94, p = .007. No statistically significant differences between groups in usual source of care (p=.069) and physical health status (p=.490) but there was a significant difference in mental health status (p=.001). Participants with CM had a poorer mental health status than those with PI and MD, F (2,619) =21.8, p= .000. The mental health status of individuals with PI was significantly better than that of participants with MD.
Awareness of disparities in the usual source of care, health services use, and health outcomes among individuals with mental health conditions is imperative if barriers to care are to be eliminated. Innovative interventions pertinent to decreasing barriers to accessing health care and improving the health outcomes among individuals with MD must be tested. Advocating for mental health care policies that reduce health care services disparities among individuals with self-reported MD must be encouraged.
