Basoglu, Fatma. "Testing For Rational Bubbles In The Turkish Stock Market." Master's thesis, METU, 2012. http://etd.lib.metu.edu.tr/upload/12614505/index.pdf.
Full textAbstract:
In this thesis we empirically examine whether the Turkish stock market is driven by rational bubbles over the period between March 1990 and February 2012. The bubble periods are estimated using a recently developed right-tailed unit root test, the generalized sup augmented Dickey-Fuller test of Phillips, Shi and Yu (2011a). Applying their bubble detection and location strategies to weekly price dividend ratio series, we find strong evidence for the existence of rational bubbles in the Turkish stock market benchmark indices as well as sector indices. Our located bubble periods may give early warning signals of the subsequent Turkish financial crisis.

Full textAbstract:
La pratique du «sans labour» (NT) se développe dans le cadre de l’agriculture de conservation des sols. Cette pratique modifie nombre de propriétés du sol comme, par exemple, la répartition du phosphore (P) dans le profil du sol. L’objectif de cette thèse est d’analyser les impacts après plusieurs décennies du NT sur le cycle biogéochimique du P et d’intégrer ces effets dans un modèle de fonctionnement. Nous avons utilisé un essai au champ de longue durée sous maïs-soja (L’Acadie, Québec, Canada) implanté sur un sol argilo-limoneux. Le dispositif était un split-plot à 4 blocs avec mouldboard plough (MP) et sans labour (NT), subdivisés par 3 doses de fertilisation en P minéral [0 (0P), 17.5 (0.5P), 35 (1P) kg P ha-1] apportées sur le maïs et localisées à 5 cm de profondeur et à 5 cm du rang de maïs.La concentration des ions phosphates du sol (Cp) test était relativement uniforme dans la couche labourée (0-20 cm) (0.08 mg P L-1), puis baissait légèrement dans 20-30 cm (0.05 mg P L-1) et davantage au-delà (0.01 mg P L-1). Sous les traitements [NT, 0.5P] et [NT, 1P] traitements, le Cp était plus élevé dans la couche 0-10 cm (0.28 et 0.19 mg P L-1) que dans la couche labourée mais baissait rapidement avec la profondeur. Cette stratification verticale sous NT était également observée pour les teneurs en P-Olsen, P-M3 et autres nutriments comme C, N et K. Après 23 et 24 années d’essai, il y avait tendanciellement moins de racines du maïs sous NT (-14%) que sous MP, probablement à cause de la présence plus importante d’adventices sous NT. Pour le soja, il y avait beaucoup plus de racines dans la couche 0-10 cm sous NT (44% de longueur total) que sous MP (21%) et inversement dans la couche 10-20 cm. Ces différences de distribution des racines sous NT et MP correspondent à la stratification de N, P, et K.Cet ensemble de données sur la distribution des racines et du phosphore a été utilisé pour i) évaluer un modèle 1D décrivant la dynamique du P sur plusieurs décennies dans la couche labourée du sol, ii) proposer un mode d’estimation de la distribution du prélèvement dans le profil de sol, et iii) développer un modèle spatialisé 2D décrivant la dynamique du P pour le traitement sans labour. Ce modèle permet de simuler l’évolution de la disponibilité en P du sol sur le long terme quels que soient les modes de préparation du sol et le régime de fertilisation P. Même si le modèle surestime parfois la disponibilité en P à proximité de la zone fertilisée, il permet de prédire la stratification du P du sol en NT et ses conséquences sur le prélèvement de P en relation avec les propriétés du sol et le développement du système racinaire. Il pourra contribuer à améliorer le raisonnement de la fertilisation phosphatée dans le contexte du sans-labourThe no-till (NT) is gaining great attention for soil preparation. This practice modifies number of soil properties such as the distribution of phosphorus (P) in the soil profile. This work aims to analyze the impacts on the biogeochemical P cycle after decades of NT and incorporate those effects in an operational model. We used a long-term field experiment under corn-soybean rotation established on a clay loam soil (L’Acadie, Quebec, Canada). The design was a split-plot plan with 4 blocks under moldboard plough (MP) and NT, subdivided by 3 doses of P [0 (0P), 17.5 (0.5P), 35 (1P) kg P ha-1] applied in corn phase and localized to 5-cm deep and 5-cm from the corn row.The phosphate ion concentration in MP was relatively constant (0.08 mg P L-1) in the tilled layer (0-20 cm), slightly lower in 20-30 cm (0.05 mg P L-1) and much lower below (0.01 mg P L-1). In [NT, 0.5P] and [NT, 1P] plots, Cp was higher (0.28 et 0.19 mg P L-1) in the 0-10 cm layer compared to the tilled layer in MP, but decreased sharply with depth. This vertical stratification in NT was also observed for P-Olsen, P-M3 and other nutrients as C, N, and K. After 23- and 24-year of experimentation, maize roots tended to be fewer (-14%) under NT than MP, probably because of increased weed infestation under NT. For soybean, more roots accumulated in the 0-10 cm layer under NT (44% of total length) than MP (21%) and vice versa for the 10-20 cm layer. Those differences in root distribution under NT and MP corresponded to the stratification of N, P, and K.This set of data on the distribution of roots and phosphorus was used i) to develop a 1D model describing P dynamics over several decades in MP, ii) to test a method to assess the spatial P uptake distribution according local root length density and soil P availability, and iii) to develop a spatial 2D model describing P dynamic in NT. This model simulates the soil P availability dynamic on long term according soil properties and crop root distribution within soil profile for different soil preparation regime and different P fertilization rate. Although the model overestimates the P availability near the localized P fertilizer, it is able to predict the soil P stratification in NT treatment and its consequences on crop P uptake. This new model will be a useful tool to improve P fertilization management in context of no-till practices

The unpredictable demand pattern during promotions leads to lost sales incurred due to frequent stock-outs, affecting the revenue and the brand of both the manufacturer and the retailer. The research focuses on finding out the root-causes of stock-outs in retail stores. It uses the audit response data that informs us of various states for zero on-shelf availability. These responses are used to create a fault-tree diagram that shows how different states could be reached. The root-causes mentioned in the fault-tree diagram are classified as either qualitative or quantitative root-causes. The credibility of quantitative root causes was established through regression analysis while store visits and interviews of different players of the supply chain helped to reason out the qualitative root-causes. Quantitative factors such as replenishment frequency, store sales volume and forecast accuracy seem to indicate a good correlation with stock-outs during promotions.

Full textAbstract:
This study was motivated by the desire to contribute to the understanding of the movement of house prices and the role of the so-called economic fundamentals in the housing market, especially within an Australian context. The core objective of this thesis is to aid understanding of the economic and other mechanisms by which the Australian housing market operates. We do this by constructing an analytical framework, or model, that encompasses the most important characteristics of the housing market. This thesis examines two important aspects of the Australian housing market: movements of house prices and changes in the net capital stock of dwellings in Australia. Movements of house prices are modelled from two perspectives: firstly, using the fundamental approach, which explains the phenomena by changes in such fundamental explanatory variables as income, interest rates, population and prices of building materials, and secondly, by analysing spatial interdependence of house prices in Australian capital cities. Changes in stock of dwellings were also modelled on the basis of a fundamental approach by states and for Australia as a whole...

PharCo (an assumed name) is a leading global healthcare company with well-recognized brands of both pharmaceutical and consumer healthcare products. As PharCo continues to expand its global presence, product stock-outs in their pharmaceutical business unit have been consistently increasing. PharCo suspected that manufacturing quality defects were a major cause of stock-outs, reducing the production yield and preventing the company from meeting customer demand. To help test this hypothesis and address the stock-out challenge, we reviewed existing research on the subject of product stock-outs within the pharmaceutical industry. To understand PharCo's manufacturing process, we conducted on-site visits and reviewed their quality control practices. Finally, we designed a mixed methods approach that combines qualitative and quantitative techniques to analyze the root causes of product stock-outs at PharCo. The analysis revealed that, instead of manufacturing quality defects, regulatory issues were the primary cause for stock-outs at PharCo. Regulatory challenges associated with developments such as new product launches, license renewals, and formulation modifications need to be addressed for PharCo to reduce their stock-out level.

Full textAbstract:
Public media and previous research have focused mainly on listing day returns of initial public offers (IPOs) by new economy companies in specific periods such as before April 2000, without examining any subsequent equity offers by new economy companies. This study addresses the issue of multiple equity offers and provides additional understanding of new economy initial and seasoned equity offers (SEOs). Without, a priori, favouring any existing explanation of initial and long-term share returns, this research tests a wide range of theories in order to provide insight into share returns of equity offerings by new economy companies listed on the Australian Stock Exchange between 1994 and 2004. In general, this thesis documents the ability of publicly available information (obtained from offer documents and company announcements to the market) to explain the returns of equity-issuing new economy companies in Australia. In other words, how useful is public information in the valuation of initial and seasoned equity offers of new economy stocks? Specifically, the thesis seeks to examine the ability of public information to explain (a) listing day and long-term returns subsequent to initial public offers by new economy companies, and the probability of IPO withdrawal, (b) announcement period and long-term returns of seasoned equity offers by new economy companies, and (c) the relationships between the initial and any subsequent equity offers by new economy companies (within three years of listing) in terms of probability of seasoned equity offer, duration between the IPO and the first SEO, and frequency of seasoned equity offers within the first three years of IPO. First, the thesis finds that public information is used by investors to value new economy stocks on listing day and in the long run. The negative effect of withdrawal probability on listing day returns of successful IPOs is confirmed in this thesis in the context of the fixed-price offer process in the new economy sector in Australia. While new economy equity-issuing companies have inferior long-term returns compared to the market index and the small capitalisation stock index, they do not underperform relative to their respective industry index returns. Second, this study also finds that public information can explain new economy stock returns around the announcements of seasoned offers and in the long run. Third, the results reveal that publicly available information can be used to explain the incidence and to estimate the probability of seasoned equity offers by recent new economy IPOs. Furthermore, it is found that public information has the ability to explain the duration between the IPO and the first seasoned offer, as well as the frequency of seasoned offers in the first three years after listing. The results of the study support the theoretical predictions about the effects of public information (representing IPO characteristics) and the incidence of a seasoned equity offer. In particular, IPO quality signalling by retained ownership and by underpricing, and the market feedback effect of post-IPO returns have been confirmed for new economy equity offers in Australia. Underpriced new economy IPOs and those with greater proportion of ownership retained after the offer are significantly more likely to have a seasoned equity offer within three years of listing. Likewise, new economy IPOs with superior aftermarket returns are significantly more likely to have a seasoned equity offer. The implication of this research is that public information contained in offer documents and in company announcements is important to valuation of the Australian Stock Exchange listed new economy companies. Thus, the regulators and the Stock Exchange should continue to insist on a high level of information disclosure prior to equity offers in order to enable investors to properly value companies within the new economy sector.

Hooi, George Wye Keong, and n/a. "An Empirical Investigation Between Culture, Investor Protection, International Banking Disclosures and Stock Returns." Griffith University. Griffith Business School, 2007. http://www4.gu.edu.au:8080/adt-root/public/adt-QGU20071121.133040.
Full textAbstract:
There is a renewed interest in further exploring the significance of culture to the accounting disclosure model in view of a highly competitive global business environment. To date, there is no empirical research to investigate this issue with respect to a specific industry, namely banking. There are three main reasons for focusing only on the banking industry (Hooi 2004). First, it is considered to be the most important industry for the countrys economic and financial stability. Moreover, the IASB has recognised its significance by issuing unique accounting standards i.e. IAS30, IAS32 and IAS39. Second, Saidenberg and Schuermann (2003) argue that with the scope and complexity of Basel II, it provides opportunities for researching issues through Pillar 3. Third, with national banking systems being non-homogenous, it is important to investigate the effects of national culture because prior research has argued that cultural differences have partly explained international differences in disclosure framework of accounting systems. The purpose of this study is to apply and extend Grays (1988) theoretical framework of national culture with respect to four research questions. First, to contribute to Grays (1988) theory of cultural influence on international banking disclosures. Second, to investigate the possible significance of investor protection to the banking disclosure model. Third, to explore Grays (1988) theory on the relationship of national culture to capital market research using banking returns. Fourth, to investigate the value relevance of investor protection and banking disclosures to the returns model. Seventeen developed and developing countries with a representative sample of 37 listed domestic commercial banks were examined in 2004. For the disclosure model, the study finds that national culture is a significant factor in the banking industry. Individualism has been found as the primary cultural dimension for banking disclosures. Moreover, the explanatory power of the model significantly improves with the legal dimensions of common law and anti-director rights. The positive association between common law and banking disclosures is consistent with La Porta et al. (1998) which argue that common law countries with stronger investor protection are more transparent than civil law countries. However, there is a negative association between investor protection variable of anti-director rights with banking disclosures. This may suggest that investor protection does not encourage minority investors to enter the stock market specifically in the global banking industry. This situation may lead to a lack of demand for transparency through a smaller dispersion of ownership across the domestic banks. For the returns model, the study finds that national culture is value relevant in the banking industry. Collectivism and power distance have been found to be the two primary cultural dimensions for banking returns. Moreover, the explanatory power of the model significantly improves with anti-director rights and banking disclosures. These results are (1) consistent with La Porta et al. (2002) which argue that investor protection increases firm valuation with respect to Tobins Q and (2) international investors tend to support the Basel Committees commitment in providing a more transparent framework by implementing Pillar 3 in the near future, starting with the Basel member countries. Finally, an interesting finding from the study is that firm size has a negative association with banking returns.

Full textAbstract:
A key theme in capital markets research examines the relationships between accounting information and firm value. Two concerns relating to the value relevance of accounting information are: (1) concerns over the explanatory and predictive power of the evidence presented in the prior literature (Lev, 1989); and (2) the evidence of a deterioration in the association between accounting information and stock prices over the past four decades (Collins, Maydew and Weiss, 1997; Francis and Schipper, 1999; Lev and Zarowin, 1999). These concerns provide the key motivation for this thesis which examines: (1) the usefulness of the clean surplus accounting equation in valuation; (2) the role of accounting information in estimating and predicting systematic risk and; (3) the changing nature of the relationship between accounting information, stock prices and risk over time. The empirical research provides evidence of the value-irrelevance of the clean surplus equation and that controlling for the functional form of the earnings-returns relationship is more important. Evidence is also provided that accounting variables are highly associated with M-GARCH risk betas and also possess predictive ability relative to these risk measures. Finally, the relationships between stock prices, risk models and accounting information are shown to have not deteriorated over time, contrary to prior evidence. Rather, the functional form of the relationship has changed from linear to a non-linear arctan association. Overall, accounting information continues to play the central role in the determination of stock prices and risk metrics.

Full textAbstract:
The U.S. Securities and Exchange Commission (SEC) continues to reform the corporate governance mechanisms in order to improve the quality of financial reporting and thus, enhance the confidence of investors in the stock market and in the accounting profession. Despite the efforts of the SEC, financial reporting scandals continue with record numbers of financial restatements documented by the General Accounting Office. A financial restatement is a correction of a previously misstated financial statement. There is a small volume of literature examining the effects of corporate governance mechanisms on financial restatements. The results of these studies however, are mixed and possibly explained by their narrow focus and omitted variables that could influence the effectiveness of audit committees. Consequently, this study examines the effects of independent audit committee member characteristics and auditor independence on financial restatements. Specifically, this study investigates the relationship between the likelihood of financial restatements and: (1) the expertise of the independent audit committee members, (2) the expertise and diligence of the independent audit committee members, (3) the reputation of the independent audit committee members, (4) the interaction effect of expertise, diligence and reputation, (5) the tenure of the independent audit committee members, and (6) the cash compensation paid to independent audit committee members. Prior studies have not investigated some of these variables or the interaction effects of independent audit committee member characteristics on financial restatements. This study also investigates the association between auditor independence and financial restatements. The SEC alleges that an increasing number of audit failures are due to the lack of auditor independence. One of the major sources of the lack of auditor independence is the auditors economic dependency on the client. The provision of non-audit services increases the financial reliance of the auditor on the client. As a result, the auditor may become reluctant to raise issues with the preparation of the financial statements at the risk of foregoing the lucrative non-audit services fees. The SEC believes that longer audit firm tenure can also impair auditor independence and Section 203 of the Sarbanes-Oxley Act suggests periodic audit firm rotation. Therefore, auditor independence was measured as: (1) fees paid to the auditor, and (2) audit firm tenure. Finally, this study extends the prior literature by studying the interaction effects of independent audit committee member characteristics and auditor independence on financial restatements. This interaction effect is important because the external auditor and the audit committee are regarded vital governance mechanisms that interact and exchange dialogue in the performance of their respective oversight of the financial reporting process. Prior research has not investigated this important interaction effect. The sample of the study comprises 69 U.S. publicly listed companies that announced their restatement from 1 January 2001 to 31 December 2002. These companies were matched with 69 non-restatement companies based on industry and size. The data for the study is derived from SEC filings such as Form 10-K and DEF 14A, and Compustat. The univariate results show that compared to restatement firms, non-restatement firms generally have effective audit committee characteristics. The audit committees of non-restatement firms have members who are experts, diligent, reputable and appropriately compensated. They also pay lower non-audit services and total fees, and have audit firms with longer tenure. The multivariate results show that after controlling for other governance structures and firm specific non-governance variables, the likelihood of financial restatements is related to independent audit committee member characteristics and auditor independence. Specifically, the likelihood of financial restatements decreases when independent audit committee members are: (1) experts, (2) experts and diligent, (3) reputable, (4) experts, diligent and reputable, and (5) appropriately compensated. The audit committee member tenure variable is insignificant. In relation to the auditor independence variables, the multivariate results show that the likelihood of financial restatements increases when the non-audit services and total fees generated by the client are higher. On the other hand, the likelihood of financial restatements decreases when audit firm tenure is longer. The empirical results of this study suggest that independent audit committees are more effective overseers of the corporate financial reporting and auditing processes when: they comprise majority experts, they meet regularly, their members are reputable, and audit committee members are appropriately compensated. On the other hand, external auditors are not deemed to be effective overseers of the corporate financial reporting process when the non-audit services and total fees generated by the client are higher but are effective when audit firm tenure is long. The results support the SECs concerns regarding the provision of non-audit services impairing auditor independence. The results also support the Sarbanes-Oxley Act of 2002 which under Section 201 prohibits external auditors from providing certain non-audit services to its audit client. Overall, these results support the regulatory efforts to increase the quality of financial reporting by enhancing the corporate governance process related to audit committees and auditor independence. However, the results do not support calls to limit the tenure of the auditor. The results of the multivariate interaction effects suggest that, after controlling for other governance structures and firm specific non-governance variables, when the non-audit services and total fees generated by the client are higher, the likelihood of financial restatements increases under conditions when the audit committee is not effective (a non expert audit committee, an audit committee that does not meet regularly, an audit committee whose members are not reputable or an audit committee that is not appropriately compensated). The implication of this result is that it provides evidence of conditions under which restatements take place. Knowledge of such conditions could aid regulators further improve the financial reporting process and corporate governance. This knowledge will support regulators in revising policies that ensure audit committee members are not only independent but also comprise other critical qualities. These improvements to the audit committee coupled with the existing regulations on the provision of non-audit services suggest a companys governance will be more effective. Overall, the results extend current knowledge in the sparse but growing literature related to financial restatements and corporate governance, and extend our understanding of the effectiveness and interaction of governance mechanisms in reducing financial restatements.

This thesis derives a first approximation model that will describe the flow of fluid in microfluidic devices such as in microchannels, microdiffusers and micronozzles using electrical network modelling. The important parameter that is of concern is the flow rates of these devices. The purpose of this work is to contribute to the physical component of our interactive Virtual Reality (VR)-prototyping tool for MEMS, with emphasis on fast calculations for interactive CAD design. Current calculations are too time consuming and not suitable for interactive CAD with dynamic animations. This work contributes to and fills the need for the development of MEMS dynamic visualisation, showing the movement of fluid within microdevices in time scale. Microfluidic MEMS devices are used in a wide range of applications, such as in chemical analysis, gene expression analysis, electronic cooling system and inkjet printers. Their success lies in their microdimensions, enabling the creation of systems that are considerably minute yet can contain many complex subsystems. With this reduction in size, the advantages of requiring less material for analysis, less power consumption, less wastage and an increase in portability becomes their selling point. Market size is in excess of US$50 billion in 2004, according to a study made by Nexus. New applications are constantly being developed leading to creation of new devices, such as the DNA and the protein chip. Applications are found in pharmaceuticals, diagnostic, biotechnology and the food industry. An example is the outcome of the mapping and sequencing of the human genome DNA in the late 1990's leading to greater understanding of our genetic makeup. Armed with this knowledge, doctors will be able to treat diseases that were deemed untreatable before, such as diabetes or cancer. Among the tools with which that can be achieved include the DNA chip which is used to analyse an individual's genetic makeup and the Gene chip used in the study of cancer. With this burgeoning influx of new devices and an increase in demand for them there is a need for better and more efficient designs. The MEMS design process is time consuming and costly. Many calculations rely on Finite Element Analysis, which has slow and time consuming algorithms, that make interactive CAD unworkable. This is because the iterative algorithms for calculating the animated images showing the ongoing proccess as they occur, are too slow. Faster computers do not solve the void of efficient algorithms, because with faster computer also comes the demand for a fasters response. A 40 - 90 minute FEA calculation will not be replaced by a faster computer in the next decades to an almost instant response. Efficient design tools are required to shorten this process. These interactive CAD tools need to be able to give quick yet accurate results. Current CAD tools involve time consuming numerical analysis technique which requires hours of numerous iterations for the device structure design followed by more calculations to achieve the required output specification. Although there is a need for a detailed analysis, especially in solving for a particular aspect of the design, having a tool to quickly get a first approximation will greatly shorten the guesswork involved in determining the overall requirement. The underlying theory for the fluid flow model is based on traditional continuum theory and the Navier-Stokes equation is used in the derivation of a layered flow model in which the flow region is segmented into layered sections, each having different flow rates. The flow characteristics of each sections are modeled as electrical components in an electrical circuit. Matlab 6.5 (MatlabTM) is used for the modelling aspect and Simulink is used for the simulation.

Full textAbstract:
This study examines the dynamic interaction between housing prices, stock prices and the repo rate in the Stockholm region by using the Johansen tests for cointegration. Several studies have been done on this topic, but the results are mixed across the world, and not many have been done in Scandinavia. This study contributes to the literature by examining eleven years of monthly data for the housing prices in the Stockholm region. We find evidence of a long-run relationship between housing prices, stock prices and the interest rate. There is a negative relationship between housing prices and the interest rate as well as between stock prices and the interest rate, but a positive relationship between housing prices and stock prices. However, the results are somewhat sensitive to model specification and therefore further studies on the topic are encouraged.

Full textAbstract:
This thesis sets out to evaluate the role of consumer spaces in twentieth-century daily life. It is not concerned with the act of consumption but rather with the ways in which the social, cultural and educative role of the retail spaces is used as a marketing tool. The links that have been established between civic and commercial space over the last three hundred years are charted in order to locate the reasoning behind the growing tendency to design shopping malls as social and cultural spaces in the twentieth century. Three principal benefits to developers of the retails spaces from the promotion of consumer spaces as public spaces are identified in the thesis. First, links between the public and commercial developed to encourage potential customers into a particular retail space as opposed to its competition. Second, consumer spaces are developed as social and leisure spaces to encourage consumer loyalty. That is, they are developed as a means of encouraging repeat visits. Third, they are developed as a tactic to keep potential shoppers in the retail space for a longer duration. The logic behind this strategy being the more time spent in a consumer space the more goods purchased. The origins of this merchandising practice are traced back to the seventeenth and eighteenth centuries well before the advent of the department store form. The thesis located a number of strategies developed in the seventeenth century by tradesmen and merchants to sell their wares. At this time, it is evident that the consumer space was opened up to the public who were encouraged to enter without the obligation to purchase. Further, it is evident that, by the eighteenth century, shopkeepers and manufacturers' workshops included showrooms where potential customers could sit and take tea. Public spaces were also designed within the retail space so that potential customers could see and be seen. British shopkeepers often linked the retail space with the social practice of promenading by strategically situating their premises in an already established thoroughfare or site used for promenading. By the late eighteenth century, consumer spaces housed entertainment facilities such as art galleries, exhibitions and lounging rooms. After tracing the development of this merchandising strategy to the eighteenth and nineteenth centuries, the links that can be made between twentieth-century consumer spaces is examined. In addition, the early developments of shopping centres in the 1940s and 1950s are surveyed and their developmental logic and merchandising strategies are compared with more recent forms of shopping malls developed from the 1970s and 1980s.

Resumo: Os processos de recebimento, conferência, armazenagem, separação de pedidos, montagem de kits, distribuição de materiais e inventário são processos vitais dentro dos almoxarifados e interferem diretamente na efetividade da Cadeia de Suprimentos (Supply Chain - SC). Como esses processos sofrem várias interferências, devido a outros processos da SC, como compra de materiais, planejamento, programação e abastecimento da produção, tornam-se comuns situações como excessos de materiais, baixa acuracidade dos estoques, dificuldade de localização, falhas no atendimento dos pedidos e montagem de kits, entre outros. Pensando nestas dificuldades gerenciais, busca-se, nesta dissertação, utilizar uma pesquisa de natureza aplicada, com objetivos empíricos e descritivos e análise quantitativa para desenvolver uma ferramenta gerencial, com base em um modelo de simulação a eventos discretos, como apoio às decisões sobre os recursos necessários para execução de forma efetiva dos processos citados. O objeto de estudo foi um almoxarifado de produtos estampados de uma empresa multinacional no setor automotivo. Onde a criação de um modelo conceitual e aplicação da simulação foram os objetivos. Adotou-se a técnica IDEF-SIM para a modelagem conceitual do problema e foi utilizado o software ProModel® para se obter uma racionalização na aplicação dos recursos necessários para que o almoxarifado tenha um melhor desempenho, frente a vários cenários possíveis de ocorrer.

Abstract: The processes of receiving, conferring, storing, sorting orders, assembling kits, distributing materials and inventory are vital processes within warehouses and directly interfere with the effectiveness of the Supply Chain (SC). As these processes suffer several interferences, due to other SC processes, such as material purchase, planning, scheduling and production supply, situations such as material excesses, low inventory accuracy, difficulty in locating, ordering and assembling kits, among others. In this dissertation, we intend to use a research of an applied nature, with empirical and descriptive objectives and quantitative analysis to develop a managerial tool, based on a simulation model to discrete events, as support to the decisions about the necessary resources to effectively execute the cited cases. The object of study was a warehouse of stamped products of a multinational company in the automotive sector. Where the creation of a conceptual model and application of the simulation were the objectives. The IDEF-SIM technique was adopted for the conceptual modeling of the problem and ProModel® software was used to obtain a rationalization in the application of the necessary resources so that the warehouse performs better, against several possible scenarios to occur. It was found after the simulation that one of the main problems in the operation of the warehouse was related to the unbalanced arrival of the items that form the kits, another one related to the excessive...

Full textAbstract:
This thesis examines the nature of labour usage within a market-leading Australian food retail firm and the employment relations consequences of the labour usage strategies employed by the firm. Retail employment is well established as a research subject in the UK, but has received comparatively little research attention in Australia. Given that retail industry employment accounts for 15 per cent of the Australian workforce, this represents a significant oversight. Within the retail industry, the supermarket and grocery sector employs 6 per cent of the Australian workforce. The sector is dominated by two major chains and is highly competitive, with a reputation for low profit margins, mundane jobs and low pay. The sector is recognised for an employment structure that is segmented with one segment holding full-time jobs with core employment conditions and the other segment, part-time jobs with poor working conditions. The dominant theory used by scholars to explain this employment structure is the dual labour market model and later iterations such as Atkinson's flexible firm model. This research assesses the value of these models, in particular Atkinson's flexible firm model, as a representation of the labour usage strategies of a market-leading Australian food retail firm. This analysis demonstrates that, in a general sense, Atkinson's model has applicability to the labour usage strategies exhibited in food retailing. The research found that, contrary to the theories of dual labour markets, a strong internal labour market operated within the firm with short hours casual employment as the port of entry. The benefits of this practice for the organisation were flexibility in labour usage and substantial wage savings, while the negative consequences were recruitment difficulties, exacerbated by high levels of staff turnover. For the employees, the consequences depended on their position in the organisational hierarchy and their individual circumstances, but involved initially accepting limited working hours and low pay in order to gain entry into the organisation. The research undertaken for this thesis leads to the development of a revised model, the casual internal labour market model, which more accurately depicts the labour usage strategies within the case study organisation. Retail researchers argue that it is necessary to understand the dynamics of the industry in order to understand the structure of labour usage. Additionally, employment relations and retail researchers both stress the need to contextualise labour usage patterns within broader environmental constraints and supply side factors. In seeking to achieve this, this research examines business strategies, retail specific employment relations literature and the Australian employment relations context. Furthermore, this study addresses the issue of retail employment strategies at several levels within one of Australia's market-leading food retailers: corporate level, store level and at the level of individual departments within the store. In doing so, this thesis highlights the differences in labour usage between stores and between departments within the stores and thereby provides a more detailed picture of the labour use practices within food retailers.

Full textAbstract:
To address the issues related to the physically demanding task of stock-picking that exists in today’s logistics industry, robots have been suggested as a means to reduce the human workload. Extensive efforts have been made by the robotics community to solve problems related to automatic stock picking. Among these problems is motion planning, which is one of the most active fields of robotics. Motion planning for robot manipulator is a complex problem due to the high dimensionality of the problem. To address this problem, trajectory optimization is introduced as an approach to solve motion planning problems in higher dimensions. This thesis reviews and evaluates trajectory optimization methods for a stock-picking robot developed at KTH. The thesis is separated into two parts, which consists of a literature study and experimentation. In the literature study, we discuss previous work within trajectory optimization and the various strengths and weaknesses. The experiments are conducted on the trajectory optimization methods GPMP2, CHOMP and STOMP in different pick-and-place scenarios. The goal of these experiments is to evaluate their performance, the quality of the trajectories they generate and their applicability for pick-and-place tasks with KTH:s ASP robot. By evaluating the results from our experiments, we conclude that the evaluated trajectory optimization methods achieved limited success in the pick-and-place scenarios. The overall performance of STOMP meets the criteria, but has difficulties in narrow passages. The experiments also showed that the addition of a kernel smoother in the obstacle cost function improve the performance of STOMP.För att ta itu med problemen relaterade till den fysiskt krävande uppgiften av lagerplockning som finns i dagens logistikindustri har robotar föreslagits som en medel för att reducera den mänskliga arbetsbelastningen. Omfattande ansträngningar har gjorts av robotforskarsamhället för att lösa problem relaterade till automatisk lagerplockning. Bland dessa problem finns rörelseplanering, som är ett av de mest aktiva områdena inom robotik. Rörelseplanering för robotmanipulatorer är ett komplext problem på grund av den höga dimensionaliteten av problemen. För att lösa detta problem introduceras banoptimering som ett tillvägagångssätt för att lösa rörelseplaneringsproblem i högre dimensioner. Denna avhandling granskar och utvärderar metoder för optimering av banor för en lagerplockrobot utvecklad vid KTH. Denna avhandling är uppdelad i två delar, som består av en litteraturstudie och experiment. I litteraturstudien diskuterar vi tidigare arbete inom banoptimering och olika styrkor och svagheter. Experimenten genomförs på banoptimeringsmetoderna GPMP2, CHOMP och STOMP i olika plockoch- placering scenarier. Målet med dessa experiment är att utvärdera deras prestanda, kvalitén av banorna de genererar och deras tillämplighet för plock-och-plats-uppgifter med KTH:s ASP robot. Genom att utvärdera resultaten från våra experiment drar vi slutsatsen att de utvärderade metoderna för optimering av banor uppnådde begränsad framgång i plock-and-placering scenarierna. STOMP:s övergripande prestanda uppfyller kraven men har svårigheter i smala passager. Experimenten visade också att tillägget av en ”kernel smoother” i kostnadsfunktionen förbättrade prestanda för STOMP.

Full textAbstract:
This dissertation focuses on the study of spectral stability in traveling waves, with a special interest in planar detonations in the multidimensional reactive Navier-Stokes equations. The chief tool is the Evans function, combined with STABLAB, a numerical library devoted to calculating the Evans function. Properly constructed, the Evans function is an analytic function in the right half-plane whose zeros correspond in multiplicity and location to the spectrum of the traveling wave. Thus the Evans function can be used to verify stability, or to locate precisely any unstable eigenvalues. We introduce a new method that uses numerical continuation to follow unstable eigenvalues as system parameters vary. We also use the Evans function to track instabilities of viscous detonations in the multidimensional reactive Navier-Stokes equations, building on recent results for detonations in one dimension. Finally, we introduce a Python implementation of STABLAB, which we hope will improve the accessibility of STABLAB and aid the future study of large, multidimensional systems by providing easy-to-use parallel processing tools.

The present work dealt with the evaluation of the tolerance to salt stress by the characterization of the influence of salinity on vegetative growth, nutrient content and distribution, gas exchanges and photochemical efficiency of the photosytem II of four commercial cultivars of mango trees grafted on the root stock Imbú . The experiment was carried out in a randomized block factorial (4 x 4) design , with 4 salt concentrations (0; 15; 30; and 45 mmol L-1 NaCl) and 4 mango cultivars ('Haden', 'Palmer', 'Tommy Atkins', and 'Ubá', all of them grafted on the root stock Imbú ), with 5 replications and 1 plant per experimental unit. The shootings were about 18 months old and were transferred from plastic bags containing substrate (3:1 earth-sand) to vases containing 7dm³ of modified Hoagland's nutrient solution. After 30 days of acclimatization to the hydroponic system, the salt concentrations were added to the nutrient solution. The shootings were submitted to salt stress for 100 days. The solution was changed every time the electrical conductivity of the control treatment reduced 20% of the initial value. 15, 25, 45, 60, 75 and 95 days after the exposure to salt stress (DAEES), the stem length, stem diameter, plant height and leaf emission were evaluated, all of them grown after the exposure to salt stress, difference in temperature (room leaf) ºC, internal concentration of CO2 (Ci), stomatal conductance (gs), transpiratory rate (E), liquid photosynthesis (A), leaf water potential (MPa) and parameters of the chlorophyll fluorescence a (F0, Fm, Fv, F0/Fm, Fv/Fm, Fv /Fm , PSII = [(Fm -Fs)/(Fm )], D = (1- Fv /Fm ) and ETR = ( PSII x FFF x 0,42). At the end of the experiment, at 100 DAEES, the plants were collected and and roots, stem and leaves were separated. The stem was subdivided into two parts: stem of the root stock and stem of the cultivar. Next, the average leaf area (cm2), total leaf area of the plant (cm2), toxicity index in the leaves (%) and the index of leaf abscission (%) were determined. The dry mass of the root, stem of the root stock stem of the cultivar, leaf and total were determined after drying in a greenhouse Then, the contents of N-total, P, K, Ca, Mg, Na and Cl were determined for the root, stem of the root stock, stem of the cultivar and leaves. The results achieved were submitted to the variance and regression analyses at the level of 5% of probability. The mango cultivars analyzed presented decreases in stem length and diameter, plant height, leaf emission, average leaf area and total leaf area of the plant. In all the cultivars, there was a decrease, in different degrees, in the gas exchanges, leaf water potential and photochemical efficiency of the photosystem II, which were intensified in the concentrations above 15 mmol L-1 NaCl. The cultivars presented decreases for the dry mass of roots, stem, leaf and total when submitted to concentrations above 15 mmol L- 1 NaCl. Increments were observed in the indexes of leaf toxicity and leaf abscission, although symptoms of leaf toxicity were not observed in 15 mmol L-1 NaCl. The nutrient absorption was reduced, and decreases were observed in the contents of essential elements, mainly in the roots and leaves. The highest contents of ions Na+ and Cl- were observed in the part of the stem next to the canopy of the plants and mainly in the leaves, as the NaCl concentrations increased. However, the distribution of ions Na+ and Cl- was more balanced in the plant organs (root, stem and leaf) when submitted to 15 mmol L-1 NaCl. The Tommy Atkins cultivar presented more tolerance to salt stress than the other cultivars evaluated.
Este trabalho teve como objetivo avaliar a tolerância ao estresse salino por meio da caracterização da influência da salinidade sobre o crescimento vegetativo, o teor e distribuição de nutrientes, as trocas gasosas e a eficiência fotoquímica do fotossistema II de quatro cultivares comerciais de mangueira enxertados sobre o portaenxerto Imbú . O experimento foi conduzido em arranjo fatorial (4 x 4) no delineamento em blocos ao acaso, sendo 4 concentrações de sal (0; 15; 30; e 45 mmol L-1 NaCl) e 4 cultivares de mangueira ('Haden', 'Palmer', 'Tommy Atkins', e 'Ubá', todos enxertados sobre o portaenxerto Imbú ) com 5 repetições e 1 planta por unidade experimental. As mudas estavam com aproximadamente 18 meses de idade e foram transferidas de sacolas plásticas contendo substrato (3:1 terra-areia) para vasos com 7dm³ de solução nutritiva de Hoagland modificada. Após 30 dias de aclimatação ao sistema hidropônico, as concentrações salinas foram adicionadas a solução nutritiva. As mudas foram submetidas a estresse salino por um período de 100 dias. A solução foi trocada sempre que a condutividade elétrica do tratamento controle reduzia 20% do valor inicial. Aos 15, 25, 45, 60, 75 e 95 dias após exposição ao estresse salino (DAEES), foram avaliadas comprimento do caule, diâmetro do caule, altura da planta e emissão foliar, todos crescidos após a exposição ao estresse salino, a diferença de temperatura (ambiente foliar) ºC, concentração interna de CO2 (Ci), condutância estomática (gs), taxa transpiratória (E), fotossíntese líquida (A), potencial hídrico foliar (MPa) e parâmetros da fluorescência da clorofila a (F0, Fm, Fv, F0/Fm, Fv/Fm, Fv /Fm , PSII = [(Fm -Fs)/(Fm )], D = (1- Fv /Fm ) e ETR = (PSII x FFF x 0,42). Ao final do experimento, aos 100 DAEES, as plantas foram coletadas e separadas em raízes, caule e folhas. O caule foi subdividido em duas partes: caule do portaenxerto e caule do cultivar copa. Em seguida foram determinados a área média da folha (cm2), área foliar total da planta (cm2), o índice de toxidez nas folhas (%) e o índice de abscisão foliar (%). A massa seca de raiz, caule do portaenxerto, caule do cultivar copa, folha e total foram determinadas após secagem em estufa. Em seguida foram determinados os teores de N-total, P, K, Ca, Mg, Na e Cl na raiz, caule do portaenxerto, caule cultivar copa e folhas. Os resultados obtidos foram submetidos à análise de variância e de regressão ao nível de 5% de probabilidade. Os cultivares de mangueira analisados apresentaram decréscimos do comprimento e diâmetro do caule, da altura de planta, da emissão foliar, da área foliar média e área foliar total da planta. Em todos os cultivares, em grau diferenciados, ocorreu decréscimo nas trocas gasosas, no potencial hídrico foliar e na eficiência fotoquímica do fotossistema II, que se intensificaram nas concentrações maiores que 15 mmol L-1 NaCl. Os cultivares apresentaram decréscimos de massa seca de raízes, caule, folha e total quando submetidos a concentrações maiores que 15 mmol L-1 NaCl. Foram observados incrementos nos índices de toxidez foliar e abscisão foliar, embora não sendo observados sintomas visíveis de toxidez foliar em 15 mmol L-1 NaCl. A absorção de nutrientes foi reduzida, sendo observadas reduções nos teores de elementos essenciais, principalmente nas raízes e nas folhas. Os maiores teores dos íons Na+ e Cl-, ocorreram na parte do caule próximo a copa das plantas e principalmente nas folhas à medida que as concentrações de NaCl foram aumentadas. No entanto, a distribuição dos íons Na+ e Cl-, foram mais equitativa nos órgãos da planta (raiz, caule e folha) quando submetidas a 15 mmol L-1 NaCl. Dentre os cultivares avaliados, Tommy Atkins apresentou-se mais tolerante ao estresse salino.

Full textAbstract:
In this paper we examine the short and long-term relations between stock price, book value and residual income. We employ a panel error correction model, estimated with Engle & Granger’s (1987) two-step procedure and the single equation methodology. The models are estimated with FE-OLS and the MG-estimator. We find that stock prices adjust previous periods equilibrium error. Further, we find that book value has short and long-term effects on stock prices. Finally, this paper finds mixed results regarding residual incomes impact on stock prices. The MG-estimator finds evidence for a short-term relationship, while the FE-OLS provides insignificant or weak support for short-term effects. FE-OLS and MG-estimator find insignificant or weak support regarding residual incomes long-term effects.

Full textAbstract:
Le système racinaire, lien essentiel entre la plante et le sol quoi qu'essentiellement invisible, reste encore aujourd'hui peu étudié dans son ensemble. Les plantes étant ancrées au sol via leur système racinaire, leurs facultés d'adaptation et de survie sont donc très dépendantes de leurs capacités à savoir tirer profit de l'espace qui les entoure, notamment par l'intermédiaire de leur système racinaire. Certains arbres font néanmoins partie des plus grands et plus anciens êtres vivants de la planète, preuve s'il en est de leur capacité d'adaptation au milieu dans lequel ils poussent et aux changements environnementaux pouvant survenir dans le temps. Dans le cas des plantations, les contraintes anthropiques imposées se heurtent parfois aux limites de cette formidable capacité d'adaptation. Les travaux développés dans la première partie de cette thèse font l'objet de deux articles publiés et se concentrent sur une revue bibliographique des connaissances sur l'enracinement profond. Le rôle vital du système racinaire pour la plante est ainsi mis en avant ainsi que ses fonctions dans le continuum sol-plante-atmosphère. Son rôle essentiel, souvent sous-estimé dans le stockage du carbone, est également abordé. Les différentes techniques permettant d'accéder aux systèmes racinaires in situ sont passées en revue et nous présentons la technique du puits d'accès que nous avons utilisé pour observer les racines jusqu'à 5 mètres de profondeur. Nous avons également développé nos propres outils de prise de vue par l'intermédiaire de scanner à plat ainsi qu'un outil d'analyse d'images ( IJ_Rizo) aujourd'hui disponible en ligne.Dans la deuxième partie du mémoire, nous nous consacrons à l'étude du système racinaire de l'hévéa adulte (Hevea brasiliensis) dans le nord-est de la Thaïlande. Premier producteur mondial de caoutchouc naturel, la Thaïlande a fortement développé ses plantations d'hévéas allant jusqu'à étendre son exploitation au-delà de sa zone climatique naturelle, dans des zones à fortes contraintes hydriques. Dans ce contexte, nous avons étudié la saisonnalité et la dynamique des racines fines pendant trois ans ainsi que leur contribution au cycle du carbone. Nous avons pu mettre en évidence la continuité de la dynamique racinaire indépendamment des périodes de défoliation mais en lien avec la saisonnalité de la pluviométrie. Nous avons également pu caractériser la faible différenciation de la dynamique racinaire de 0 à 4,5 mètres de profondeur dans un tel contexte. La troisième partie de la thèse concerne l'étude du teck (tectona grandis), espèce endémique d'Asie du Sud-Est, et notamment du Laos dans la région de Luang Prabang. Le développement de sa culture sous forme de plantations mono-spécifiques se poursuit depuis les années 80. En appliquant la technique d'exclusion de pluie pendant 2 ans sur des arbres d'une plantation d'une vingtaine d'années, nous avons observé l'influence du régime de précipitations sur l'enracinement. Un arrêt pratiquement total de croissance des racines en surface et en profondeur a ainsi été mis en évidence. Nous concluons, dans le cas d'espèces à une forte dépendance à la ressource en eau de surface, à un impact direct sur l'état physiologique et une stagnation de la croissance des troncs. Certains individus ont démontré une capacité d'adaptation en modifiant leur cycle de foliation / défoliation accompagné d'une reprise de la croissance des troncs lors de la deuxième année du régime de sécheresse imposé. Nous avons également démontré l'importance de l'enracinement fin pour le stockage du carbone qui, dans ce contexte, représente plus de 45 % du carbone total, soit environ le double des données publiées dans la littérature.Les données obtenues pour les espèces étudiées dans ce mémoire pourront être utilisées pour la modélisation de scenarios simulant le changement climatique et le changement d'usage des terresThe root system is essential but essentially invisible. Plants are anchored to the soil through their root system; their adaptation and survival abilities are highly dependent on their ability to learn to take advantage of the space that surrounds them. Certain trees are nevertheless some of the largest and oldest living species on the planet- evidence of their ability to adapt to changes in their environment. Within managed anthropogenic constraints, particular species are vulnerable. It is clear that a wide range of parameters are likely to influence the root system and its operation, which offers many entry points to improve our understanding of a root's capacity for expansion, its dynamics, its role within the plant itself and within the soil plant atmosphere continuum. Available data on the extent and dynamics of plant roots includes several thousand references. However, the vast majority of these observations were made within the first meter of the soil profile. Data acquisition for the fine and/or deep roots is currently limited by constraints of time and financial resources. To overcome this lack of information, while trying to assess root dynamics under different environmental conditions, many models have been developed. However, it is still difficult to describe the complexity of root development in the community and to integrate its "plasticity".To understand such a complex environment, we must work toward establishing a definition of objectives and the tools necessary to develop and implement them. The work developed in the first part of this thesis is the subject of two articles and focuses on a literature review about deep roots. The vital role of the root system for the plant is well highlighted, as is its impact as a link within the atmosphere. We discuss the role of deep roots in carbon storage, which is critical and often underestimated. The different techniques for accessing the root systems in situ are also considered, and we present our access technique for observing the roots down to depths of five meters. We have also developed tools for shooting through a flatbed scanner and image analysis ( IJ_Rizo ) now available online.In the second part of the thesis, we focus on the study of root systems of adult rubber trees (Hevea brasiliensis L. RRIM 600) in the northeast of Thailand. Thailand has greatly expanded its acreage to extend its operations beyond its natural climate zone, into areas of high water stress. In this context, we studied the seasonality and dynamics of fine roots for three years and their contribution to the carbon cycle. We were able to highlight the continuity of root dynamics during independent periods of defoliation, yet link these to the seasonality of rainfall. We were also able to characterize the low differentiation of root dynamics at 0 to 4.5 m of depth in this context.The third part of the thesis concerns the study of teak particular to the region of Luang Prabang, Laos. By applying the rain exclusion technique for 2 years on a plantation of twenty-year-old trees, we observed the influence of precipitation patterns. During the period of water stress, an almost total cessation of root growth, at the surface and significant depths, has been highlighted. We conclude that in the case of species with a high dependence on water resources there is a direct impact on the physiological state and stagnated trunk growth. Some individuals have demonstrated an ability to adapt by changing their foliation/defoliation cycle, accompanied by a resumption of trunk growth during the second year of imposed drought. We also demonstrated the importance of rooting as a means of carbon storage, which in this context represents more than 45% of total carbon- roughly double the amount published in other literature .The data obtained for the species studied in this paper can be used for modelling scenarios simulating climate change and changing land use

Foram utilizados os testes Augmented Dickey-Fuller (ADF), os testes de rácio de variância automático assim como os rácios de variâncias individuais e múltiplos propostos por Lo e Mackinlay, e Chow e Denning, respetivamente. Os vários testes utilizados para confirmar a hipótese de passeio aleatório das dezoito ações assim como do índice PSI-20, obtiveram resultados mistos contra a hipótese testada. Enquanto o teste Augmented Dickey-Fuller (ADF) rejeitou a hipótese de raiz unitária para todas as ações e também para o índice PSI-20 confirmando assim um passeio aleatório. Por outro lado, os testes de rácios de variâncias, rejeitam a hipótese testada para algumas das ações consideradas assim como para o índice PSI-20, contudo tende esse número de ações tende a diminuir quando se utiliza as cotações mensais.
This paper investigates the efficiency of the eighteen stocks that constitute the main Portuguese stock index, the PSI-20 of the Lisbon Stock Exchange. Tools used for the investigation were daily and monthly data from January 1999 to May of 2015, using the Augmented Dickey-Fuller (ADF) test, the automatic variance ratio by Choi and the individual and multiple variance ratios, by Lo and Mackinlay, and, Chow and Denning, which test the efficiency of the eighteen stocks and PSI-20 index. The Augmented Dickey-Fuller (ADF) tests the null hypothesis that the series has a unit root, while the variance ratio tests the random walk hypothesis. Based on these tests, the results provide mixed evidence against the random walk hypothesis. The results for the unit root tests do not reject the efficient market hypothesis for the entire sample, while the results from the variance ratio tests do, but tend to decrease in monthly data.

Full textAbstract:
La polarisation est le phénomène qui décrit les orientations des oscillations des ondes lumineuses qui sont limitées en direction. La lumière polarisée est largement utilisée dans le règne animal,à partir de la recherche de nourriture, la défense et la communication et la navigation. Le chapitre (1) aborde brièvement certains aspects importants de la polarisation et explique notre problématique de recherche. Nous visons à utiliser un capteur polarimétrique-catadioptrique car il existe de nombreuses applications qui peuvent bénéficier d'une telle combinaison en vision par ordinateur et en robotique, en particulier pour l'estimation d'attitude et les applications de navigation. Le chapitre (2) couvre essentiellement l'état de l'art de l'estimation d'attitude basée sur la vision.Quand la lumière non-polarisée du soleil pénètre dans l'atmosphère, l'air entraine une diffusion de Rayleigh, et la lumière devient partiellement linéairement polarisée. Le chapitre (3) présente les motifs de polarisation de la lumière naturelle et couvre l'état de l'art des méthodes d'acquisition des motifs de polarisation de la lumière naturelle utilisant des capteurs omnidirectionnels (par exemple fisheye et capteurs catadioptriques). Nous expliquons également les caractéristiques de polarisation de la lumière naturelle et donnons une nouvelle dérivation théorique de son angle de polarisation.Notre objectif est d'obtenir une vue omnidirectionnelle à 360 associée aux caractéristiques de polarisation. Pour ce faire, ce travail est basé sur des capteurs catadioptriques qui sont composées de surfaces réfléchissantes et de lentilles. Généralement, la surface réfléchissante est métallique et donc l'état de polarisation de la lumière incidente, qui est le plus souvent partiellement linéairement polarisée, est modifiée pour être polarisée elliptiquement après réflexion. A partir de la mesure de l'état de polarisation de la lumière réfléchie, nous voulons obtenir l'état de polarisation incident. Le chapitre (4) propose une nouvelle méthode pour mesurer les paramètres de polarisation de la lumière en utilisant un capteur catadioptrique. La possibilité de mesurer le vecteur de Stokes du rayon incident est démontré à partir de trois composants du vecteur de Stokes du rayon réfléchi sur les quatre existants.Lorsque les motifs de polarisation incidents sont disponibles, les angles zénithal et azimutal du soleil peuvent être directement estimés à l'aide de ces modèles. Le chapitre (5) traite de l'orientation et de la navigation de robot basées sur la polarisation et différents algorithmes sont proposés pour estimer ces angles dans ce chapitre. A notre connaissance, l'angle zénithal du soleil est pour la première fois estimé dans ce travail à partir des schémas de polarisation incidents. Nous proposons également d'estimer l'orientation d'un véhicule à partir de ces motifs de polarisation.Enfin, le travail est conclu et les possibles perspectives de recherche sont discutées dans le chapitre (6). D'autres exemples de schémas de polarisation de la lumière naturelle, leur calibrage et des applications sont proposées en annexe (B).Notre travail pourrait ouvrir un accès au monde de la vision polarimétrique omnidirectionnelle en plus des approches conventionnelles. Cela inclut l'orientation bio-inspirée des robots, des applications de navigation, ou bien la localisation en plein air pour laquelle les motifs de polarisation de la lumière naturelle associés à l'orientation du soleil à une heure précise peuvent aboutir à la localisation géographique d'un véhicule

Full textAbstract:
Le dépérissement du pommier est une maladie tellurique causée par plusieurs espèces Pythiacée. Il est responsable de graves dommages et de pertes d'arbres dans de nombreux vergers en Tunisie. Comme la lutte chimique contre cette maladie pose des problèmes éco toxicologiques et les moyens prophylactiques ont des efficacités limitées, d’autres moyens de lutte sont activement recherchés. L’objectif de cette thèse était d’identifier un nouvel agent de lutte biologique contre les oomycètes responsables de cette maladie à partir d’une collection d’isolats fongiques et bactériens Tunisiens comme alternative au contrôle chimique. Les isolats fongiques étudiés appartenaient aux genres Trichoderma, Aspergillus et Penicillium spp., les isolats bactériens appartenaient au genre Bacillus spp. clade subtilis. Les isolats fongiques ont fortement inhibé la croissance in vitro des Pythiacées (> 40%) par rapport aux isolats bactériens ; en particulier, les filtrats de culture des isolats A. westerdijkiae A7 et T. simmonsii A2. L'évaluation de l’activité préventive et curative contre les Pythiacées sur des porte-greffes du pommier de ces deux isolats fongiques et de la souche Bacillus B2 a montré que T. simmonsii A2 était le plus efficace lorsqu'il était appliqué à titre préventif. De même, la combinaison de la souche Bacillus B2 et de l’isolat A. westerdijkiae A7 a induit une bonne protection contre les Pythiacées en préventif. La combinaison des isolats T. simmonsii A2 et A. westerdijkiae A7 a entraîné une meilleure protection en traitement curatif, alors que la combinaison des trois isolats ensemble réduisait fortement l’activité protectrice. Notre étude révèle le potentiel des isolats Tunisiens, seuls ou en combinaison, en tant qu'agents de lutte biologique contre le dépérissement du pommier ainsi qu'un effet bénéfique supplémentaire sur la croissance végétale observé au niveau des racines et de la longueur des tiges. Ainsi, nous avons sélectionnés les meilleurs candidats agissant par antibiose pour l'identification des principaux agents actifs responsables de l'activité anti-oomycète. L'isolat A. westerdijkiae A7 a été retenu avec 100% d'inhibition de la croissance mycélienne des isolats de Pythiacées testés. Plusieurs étapes de purification successives du filtrat de culture ont permis d’identifier l'acide pénicillique (acide 3-méhoxy-5-méthyl-4-oxo-2,5-hexadiénoïque) en tant que principale molécule responsable de l’inhibition la croissance mycélienne des Pythiacées testées. Étant donné que l’acide pénicillique possède des propriétés toxiques pour la santé humaine et animale, l’isolat A. westerdijkiae A7 ne pourra pas être utilisé en tant que BCA puisqu’il produit cette mycotoxine malgré nos résultats prometteurs in planta. L’ensemble de ces travaux montre le potentiel anti-oomycète des micro-organismes in vitro qui peut différer de l’activité protectrice contre les Pythiacées in planta. Ils révèlent également la nécessité de caractériser l’ingrédient actif pour les études de toxicité nécessaire au développement d’un produit de bio-contrôleApple dieback is a telluric disease caused by several Pythiaceae species. It is responsible for serious damage and loss of trees in many orchards in Tunisia. As the chemical control of this disease poses eco-toxicological problems and the prophylactic means have limited effectiveness, other means of fight are actively sought. The objective of this thesis was to identify a new biological control agent against oomycetes responsible for this disease from a collection of Tunisian fungal and bacterial isolates as an alternative to chemical control. The fungal isolates studied belonged to the genera Trichoderma, Aspergillus and Penicillium spp., The bacterial isolates to the genus Bacillus spp. clade subtilis. Fungal isolates strongly inhibited the growth of Pythiaceae in vitro (> 40%) compared to bacterial isolates; in particular, the culture filtrates of isolates A. westerdijkiae A7 and T. simmonsii A2. The evaluation of the preventive and curative activity against Pythiaceae on apple rootstocks of these two fungal isolates and of the Bacillus B2 strain showed that T. simmonsii A2 was the most effective when applied preventively. Likewise, the combination of the Bacillus B2 strain and the A. westerdijkiae A7 isolate induced good protection against Pythiaceae as a preventive measure. The combination of the T. simmonsii A2 and A. westerdijkiae A7 isolates resulted in better protection in curative therapy, while the combination of the three isolates together greatly reduced the protective activity. Our study reveals the potential of Tunisian isolates, alone or in combination, as biological control agents against apple dieback as well as an additional beneficial effect on plant growth observed at the level of the roots and the length of the stems. Thus, we have selected the best candidates acting by antibiosis for the identification of the main active agents responsible for anti-oomycete activity. The A. westerdijkiae A7 isolate was retained with 100% inhibition of mycelial growth of the Pythiaceae isolates tested. Several successive purification steps of the culture filtrate made it possible to identify penicillic acid (3-mehoxy-5-methyl-4-oxo-2,5-hexadienoic acid) as the main molecule responsible for inhibiting growth mycelia of the Pythiaceae tested. Since penicillic acid has toxic properties for human and animal health, isolate A. westerdijkiae A7 cannot be used as BCA since it produces this mycotoxin despite our promising results in planta. All of this work shows the anti-oomycete potential of microorganisms in vitro, which may differ from the protective activity against Pythiaceae in planta. They also reveal the need to characterize the active molecule for the toxicity studies necessary for the development of a biocontrol product

Full textAbstract:
Sizing (hydrophobization) is one of the most important process steps within the added-value chain of about 1/3rd of the worldwide produced paper & board products. Even though sizing with so-called reactive sizing agents, such as alkenyl succinic anhydride (ASA) was implemented in the paper industry decades ago, there is no total clarity yet about the detailed chemical and physical mechanisms that lead to their performance. Previous research was carried out on the role of different factors influencing the sizing performance, such as bonding between ASA and cellulose, ASA hydrolysis, size revision as well as the most important interactions with stock components, process parameters and additives during the paper making process. However, it was not yet possible to develop a holistic model for the explanation of the sizing performance given in real life application. This thesis describes a novel physico-chemical approach to this problem by including results from previous research and combining these with a wide field of own basic research and a newly developed method that allows tracing back the actual localization of ASA within the sheet structure.
The carried out measurements and trial sets for the basic field of research served to evaluate the stock and process parameters that most dominantly influence the sizing performance of ASA. Interactions with additives other than retention aids were not taken into account. The results show that parameters, such as the content of secondary fibers, the degree of refining, the water hardness as well as the suspension conductivity, are of highest significance. The sample sets of the trials with the major impacting parameters were additionally analyzed by a newly developed localization method in order to better understand the main influencing factors.
This method is based on optical localization of ASA within the sheet structure by confocal white light microscopy. In order to fulfill the requirements at magnification rates of factor 100 optical zoom, it was necessary to improve the contrast between ASA and cellulose. Therefore, ASA was pretreated with an inert red diazo dye, which does not have any impact on neither the sizing nor the handling properties of ASA. Laboratory hand sheets that were sized with dyed ASA, were analyzed by means of their sizing performance in correlation to measurable ASA agglomerations in the sheet structure. The sizing performance was measured by ultrasonic penetration analysis. The agglomeration behavior of ASA was analyzed automatically by multiple random imaging of a sample area of approx. 8650 µm² with a minimum resolution for particles of 500 nm in size. The gained results were interpreted by full factorial design of experiments (DOE). The trials were carried out with ASA dosages between 0% and 0.8% on laboratory hand sheets, made of 80% bleached eucalyptus short fiber kraft pulp and 20% northern bleached softwood kraft pulp, beaten to SR° 30, produced with a RDA sheet former at a base weight of 100 g/m² oven dry.
The results show that there is a defined correlation between the ASA dosage, the sizing performance and the number and area of ASA agglomerates to be found in the sheet structure. It was also possible to show that the agglomeration behavior is highly influenced by external factors like furnish composition and process parameters. This enables a new approach to the explanation of sizing performance, by making it possible to not only examine the performance of the sizing agent, but to closely look at the predominant position where it is located in the sheet structure. These results lead to the explanation that the phenomenon of sizing is by far not a pure chemical process but rather a more physical one. Based on the gained findings it was possible so far to optimize the ASA sizing process in industrial-scale by means of ~ 50% less ASA consumption at a steady degree of sizing and improved physical sheet properties.

Full textAbstract:
Berry sensory assessment (BSA) is a technique that can help grapegrowers and winemakers make decisions about harvest date and grape product allocation. BSA as a structured technique has been used by grapegrowers, winemakers and researchers for the last thirteen years. However the number of studies reporting results of the effect of viticultural practices on berry sensory characteristics and wine quality is limited. This thesis examined the BSA technique through four different studies. Study one is a combined review literature review and industry survey paper in which the methodology of Berry Sensory Assessment is presented and the research conducted using BSA is discussed. It also presents the results of a survey channeled to Australian grapegrowers and Australian and New Zealand winemakers about their experience using BSA, their perceptions on its use and their suggestions for improving the methodology. It was evident from the survey that 90% of grapegrowers and winemakers use BSA and they want to understand the link between BSA and wine quality. These results demonstrated the importance of BSA for wine producers and the need for further improvement. The aim of study number two was to determine if berry sensory attributes and berry compositional variables could predict wine sensory attributes, wine compositional variables and wine quality in Shiraz. The analyses of berry and wine sensory attributes, compositional measures and wine quality using partial least squares regression and Pearson’s correlations from two seasons identified several relationships between berry sensory attributes and wine sensory attributes and quality. A significant negative relationship was identified between seed bitterness and wine savoury spice flavour for the two seasons. The berry sensory attribute pulp detachment from the skin was identified as a predictor of various wine sensory attributes (eg. the harder to detach skin from the pulp the higher intensity for wine body colour, rim colour and dark berry aroma) and wine quality scores in the season 2011. The aim of study number three was to determine if berries stored at -20°C for three months could be used instead of fresh berries to conduct BSA. Being able to conduct BSA on frozen berries could help to reduce sensory fatigue in assessors by allowing them to evaluate samples over a longer time period and to schedule BSA away from the busy harvest period. The results of this study determined that sensory profile from Shiraz berries differed in five sensory attributes – pulp sweetness, pulp fresh fig flavour, skin colour extraction, skin bitterness and seed astringency - between fresh and frozen berries at three times of harvest, preventing the evaluation of these five sensory attributes in Shiraz frozen berries. Study number four aimed to determine the effect of three rootstocks on sensory and compositional differences of Shiraz grapes and wines in comparison to a nongrafted control. The trial was conducted over two seasons. Berry and wine sensory and compositional differences were found between the grafted treatments and the nongrafted control. PCA was able to discriminate the wines from the four treatments in three groups of aroma compounds (acetate esters, ethyl esters and higher alcohols) in both seasons. The results of wine quality scores from two seasons showed that the un-grafted treatment had the lowest quality and 110 Richter and Schwarzmann the highest. The findings from this study identified relationships between the sensory and compositional variables in berries and wines that are affecting wine quality. It also showed that that the use of rootstocks has an impact on berry and wine sensory and compositional characteristics.Thesis (Ph.D.) (Research by Publication) -- University of Adelaide, School of Agriculture, Food and Wine, 2015.

In this study, we use the threshold unit root test proposed by Caner and Hansen (2001) to re-investigate the time-series properties of stock prices for the G-7 stock markets during the 2000.01 to 2009.05 period. The empirical results from our threshold unit test indicate that the null hypothesis of I(1) unit root in stock prices can not be rejected for any of the G-7 countries, with the exception of France. Our results highlight the weak-form efficient market hypothesis does hold in these G-7 stock markets, with the exception of the French market.

Stock price stationarity has several important economic implications. This paper applies the recently developed Fourier unit root test to re-examine weak form efficiency for Asia’s 13 major stock markets, during July 1997 to December 2012. Empirical results from two conventional unit root tests indicate that these stock markets are weak form efficient. However, conducting the unit root test with a Fourier function showed that most stock markets are not weak form efficient, with exceptions including Japan (quarterly data), Singapore (weekly data), and Taiwan (quarterly data). By considering two time windows of crises, Asian financial crisis (1997-1999) and Global economic crisis (2007-2009) show results that both support the not weak form efficient for all frequencies. Investors thus can benefit through arbitrage from profitable opportunities across these markets.

In this research, An MSN robot for automatic stock knowledge sharing was developed to provide investors an online platform to access historical stocks data, advice on buy-sell stock and to share stock knowledge amongst investors. The knowledge-sharing platform has three functional objectives. Firstly, A real-time information sieving on stock to be investors, Secondly, the system will be based on important stock investment information, resulting in investment-related indicators, the stock available to investors as a reference for investment, Third and final, information are collected from different stock investors to provide a for the small stock investor community to pool knowledge that can be used as a reference for the possible buy-sell time of stocks. A MSN-based stock investment robot is developed on the DotMSN agent real-time technique. Investors can select stocks with interactive information sharing. Investors can also access stocks indicators calculated from analyzed stock data. Advices from the web stock community are pooled and provided to investors as a confidence stock indicator for an added indicator to make investment decision. The novel MSN robot developed for stock investors built on the popular MSN platform should be easy to use and the confidence stock indicator from collaborative advices of the web stock community should provide investors a powerful investment decision making mechanism.
