Facco, Pierantonio. « DEVELOPMENT OF MULTIVARIATE STATISTICAL TECHNIQUES FOR QUALITY MONITORING IN THE BATCH MANUFACTURING OF HIGH VALUE ADDED PRODUCTS ». Doctoral thesis, Università degli studi di Padova, 2009. http://hdl.handle.net/11577/3426077.
Texte intégralNonostante i processi batch siano relativamente semplici da configurare e da gestire anche con un livello limitato di automazione e una conoscenza ridotta dei meccanismi che ne stanno alla base, spesso è difficile assicurare una qualità del prodotto finito riproducibile ed elevata. La strumentazione comunemente utilizzata nella pratica industriale riesce solo raramente a fornire misure in tempo reale della qualità di un prodotto. Inoltre, molte complicazioni nascono dalla natura multivariata della qualità, la quale dipende da una serie di parametri fisici, operativi o addirittura soggettivi. Sebbene le informazioni sulla qualità del prodotto non siano facilmente accessibili, esse sono racchiuse nelle variabili di processo abitualmente registrate dai calcolatori di processo e memorizzate in banche di dati storici. I metodi statistici multivariati permettono di ridurre la dimensione del problema proiettando le variabili di processo in uno spazio di dimensioni ridotte costituito di variabili fittizie che sono in grado di mantenere tutto il contenuto informativo sulla qualità, superando i problemi del rumore di misura delle variabili, della ridondanza e dell’elevato grado di correlazione. Inoltre, questi metodi sono in grado di trattare dati anomali o dati mancanti. Lo scopo di questa Tesi di Dottorato è di sviluppare dei sistemi innovativi per il monitoraggio della qualità di prodotti dall’alto valore aggiunto mediante tecniche statistiche multivariate. In particolare, i contributi scientifici di questo progetto di Dottorato sono: • l’elaborazione di tecniche per lo sviluppo di sensori virtuali per la stima in tempo reale della qualità del prodotto in sistemi produttivi di tipo batch; • l’applicazione non convenzionale di tecniche di proiezione su sottospazi latenti al fine di prevedere la durata di un batch o delle relative fasi operative; • lo sviluppo di metodiche innovative per il monitoraggio multirisoluzione e multivariato della qualità mediante l’analisi di immagini di un prodotto dall’alto valore aggiunto. Innanzi tutto, in questa Tesi vengono proposti sensori virtuali per la stima in linea della qualità del prodotto. Essi sono stati sviluppati e implementati prendendo in considerazione il caso di studio un processo industriale reale per la produzione di resine mediante polimerizzazione batch. I sensori virtuali proposti sono basati sulla tecnica statistica multivariate della proiezione su strutture latenti (PLS), che opera una regressione delle misure di processo usualmente disponibili in linea in tempo reale. Questo sistema riesce a garantire una accuratezza delle stime della qualità che è dello stesso ordine di grandezza delle misure di qualità fatte in laboratorio, col vantaggio che le stime in linea sono disponibili con altissima frequenza (sull’ordine di grandezza di s-1), cioè una frequenza centinaia di volte superiore delle misure che possono essere fatte in laboratorio (sull’ordine di grandezza di h-1). Inoltre, le stime sono accessibili in tempo reale e senza il ritardo che è tipico delle misure di laboratorio. Al fine di compensare le non linearità dei dati e i cambiamenti nella struttura di correlazione fra le variabili, la procedura adottata divide il batch in una sequenza di un numero limitato di fasi di stima, all’interno delle quali lo stimatore virtuale è in grado di dare stime molto accurate per mezzo di modelli PLS lineari. Il passaggio da una fase a quella successiva avviene in corrispondenza di alcuni “eventi” facilmente riconoscibili nelle stesse variabili di processo. La caratteristica principale del sensore virtuale proposto è che esso tiene conto di informazioni sulla dinamica del processo per mezzo di modelli a “variabili ritardate” (i quali aggiungono informazioni sulla dinamica del processo da valori passati delle variabili di processo) o modelli a media mobile. Il filtro a media mobile aggiunge una “memoria temporale” al sensore virtuale che migliora l’accuratezza di stima e, mediando le variabili di processo all’interno di una finestra temporale di dimensione fissata, riesce ad eliminare il rumore di misura, attenuare il rumore di processo, appiattire valori anomali e compensare l’effetto di temporanee mancanze di dati. L’ampiezza della finestra deve comunque essere scelta con cautela, dato che una finestra temporale troppo larga potrebbe ritardare gli allarmi sull’attendibilità della stima. Da un punto di vista operativo, il sistema proposto aiuta il personale che opera nell’impianto a rilevare delle derive sulla qualità del prodotto, suggerisce tempestivamente le correzioni da apportare alla ricetta del processo, e aiuta a minimizzare i fuori specifica del prodotto finale. Inoltre, il numero di campioni per la misura della qualità in laboratorio può essere ridotto drasticamente, la qual cosa determina un guadagno sia sul tempo totale del batch, sia sui costi relativi al laboratorio che alla manodopera e alla sua organizzazione. Anche una seconda tipologia di sensori virtuali è stata sviluppata per assistere il monitoraggio in linea della qualità del prodotto e per fornire informazioni utili per una programmazione efficace della produzione: un sensore virtuale per la previsione in tempo reale della durata del batch. Questa strategia di monitoraggio si basa su modelli PLS evolutivi che sfruttano le informazioni progressivamente raccolte nel tempo durante il batch per prevedere la durata del batch o di ciascuno dei relativi stadi operativi. Anche l’accuratezza ottenuta dalle previsioni ottenute con questo sensore virtuale è del tutto soddisfacente, dato che l’errore di previsione è molto inferiore sia alla variabilità delle durata del batch che alla durata dei turni di lavoro degli operatori. Inoltre, la parte iniziale del batch conferma di essere di importanza fondamentale per la durata, in quanto le condizioni iniziali delle attrezzature, lo stato delle materie prime, e la fase di riscaldamento iniziale del reattore esercitano una grandissima influenza sulle prestazioni del batch stesso. Le informazioni che si ricavano sulla durata con grande anticipo rispetto alla fine del batch permettono una migliore organizzazione degli interventi sull’impianto, degli operatori d’impianto e dell’utilizzazione delle apparecchiature. L’efficacia dei sensori per la stima della qualità e per la previsione della durata del batch è stata verificata applicandoli ed implementandoli in linea nel caso della produzione di resine mediante polimerizzazione batch. Infine, i metodi statistici multivariati sono stati utilizzati anche nel campo dell’analisi dell’immagine. Abitualmente, nella pratica industriale, le ispezioni di un prodotto mediante analisi dell’immagine vengono svolte con semplici misurazioni dei più importanti parametri fisici opportunamente messi in evidenza per mezzo di tecniche di filtrazione. Inoltre, queste misure vengono ottenute in modo non sistematico. Molte informazioni utili restano però “nascoste” nelle immagini. Queste permettono di identificare la natura complessa della qualità del prodotto finale. Per questo è stato sviluppato un sistema totalmente automatizzato per il monitoraggio in tempo reale da immagini di un manufatto dall’alto valore aggiunto. Questo sistema di monitoraggio basato su tecniche multirisoluzione e multivariate è stato applicato al caso della caratterizzazione della superficie di un semiconduttore dopo fotolitografia, un’operazione fra le più importanti nella fabbricazione di circuiti integrati. Tecniche avanzate di analisi multivariata dell’immagine estraggono le tracce che il processo lascia sul prodotto, aiutando sia il rilevamento di situazioni critiche nel processo che l’intervento con azioni correttive a neutralizzare eventuali problemi. L’approccio proposto in questa Tesi si basa su un filtraggio preliminare multirisoluzione dell’immagine mediante wavelet, seguito da uno schema di monitoraggio che conduce in parallelo un’analisi della rugosità superficiale e della forma della superficie di un prodotto. Ad esempio, la rugosità della superficie può essere esaminata con una analisi delle componenti principali “nidificata”. Questa è una strategia che si articola su due differenti livelli: il livello esterno che permette di discriminare parti differenti della superficie per mezzo di una analisi dei gruppi con PCA; il livello interno esegue il monitoraggio della rugosità superficiale con PCA. La forma della superficie viene analizzata per mezzo di un approccio PCA a “finestra mobile nello spazio”, il quale coglie l’informazione dell’immagine secondo il relativo ordine nello spazio e riesce anche a tener conto sia delle non linearità che delle differenze strutturali della superficie. Questo sistema è in grado di rilevare alcune delle caratteristiche qualitative del prodotto che abitualmente non sono accessibili senza richiedere l’intervento dell’uomo. Inoltre, il monitoraggio risulta essere veloce, attendibile e non ambiguo, ed esegue una scansione di un’immagine del prodotto localizzando in modo preciso difetti e anomalie e rilevando eventuali derive del processo. In conclusione, nonostante le metodologie proposte siano state testate su specifici casi di studio, esse hanno dimostrato di essere generali e vantano un grande potenziale. Per questo si ritiene sia possibile estenderle a differenti campi di ricerca e a diverse applicazioni industriali (ad esempio: ingegneria alimentare; industria farmaceutica; biotecnologie; etc…), nonché a differenti scale di indagine, dalla scala macroscopica alla microscopica o nanoscopica.

Texte intégralThe purpose of the study is to find out what subcontractors can do to increase customer value in the process from announcement to delivered service. The customer in this study is the building contractor. By giving subcontractors the knowledge of how to improve their process, improvements for the construction industry in general can be made. The study is based on information from interviews with eight building contractors and information from scientific articles. Interviews have claimed that several factors and activities can create customer value. The relation between building- and subcontractors is a significant factor when building contractors choose who they will send an offer request to. In a competitive position the price is more important. In that case the building contractors will send out offer requests to a bigger number of subcontractors, to get the lowest bid possible. The bid should be clearly presented and show what is included. Most building contractors value when subcontractors exploit their expertise and propose improvements in the bid. The proposition could benefit all parties in the supply chain; the client, the building contractor and the subcontractor. The price is always a significant factor but interviews has claimed that it is not always crucial. Experiences of cooperation with the subcontractor in earlier project has proved to be as important. In production communication is important. Through good communication between all parties in a project misunderstandings can be reduced and processes improved. Commitment, accessibility, information and feedback are factors that is important through the entire process from announcement to delivered service. By reporting directly to any changes, the entire project is improved and unnecessary costs can be avoided. Upon completion of a project all documents must be submitted in time.

Texte intégralIntroduction: The retail market in the 21st century will be determined on how quickly and efficiently the retailer can respond to shifts in consumer demands. Due to the physical environment of the store (store value) and the interaction with the consumer (shopping trip value), the local retail store has the advantage of generating this tangible and intangible information. It is then of importance that this information will be transferred towards the retailer, who has the opportunity to use this information and generate it into outputs that can be used as negoitables; this value creation process is an unique success indicator for creating a value network within retail supply chain.
Purpose: The aim of this research is to present an understanding on the value creation process in the grocery retail chain.
Methodology: Having an inductive nature, this thesis tried to bring a new understanding on value creation in grocery retail business, by using hermeneutics as a methodology approach. For empirical study, the qualitative approach was used. Data was collected through open-ended interviews with representatives in grocery retail chains.
Conclusion: The main players in the value network were determined in a grocery retail chain as retailer, local retail store and other stores in the chain; and the suppliers. An intensive value exchange between the retail store and the retailer was found and following that, it was concluded that the retailer converts the value input from the local retail store into tangible and intangible value outputs towards suppliers. Combining the conclusions, the research defines that a value network is existing, but on a very low level. But more to the point, the study shows the importance of value creation by the retail chain, and that creating the possibility to share information about products, in-store experience, consumer knowledge, and consumer requirements is one of the biggest advantage the grocery retail chain has to develop this value network further.

Texte intégralDe nombreux produits d'usage courant ont été conçus en modifiant des produits déjà existants. L'évolution constante des tendances du marché actuel et la demande croissante des clients pour des produits de qualité forcent les entreprises à effectuer des modifications fréquentes en vue de créer de nouveaux produits. Les défis associés à la modification de produit ont incité beaucoup d'entreprises à développer une stratégie de conception adaptative permettant de créer de nouveaux produits en améliorant de manière incrémentielle les produits existants. Ce mémoire propose un système d'aide à la décision visant à appuyer les gestionnaires en développement de produits dans l'analyse des mesures de performance d'un projet tels que l'effort et le temps de développement, le coût et le potentiel de revenu, la satisfaction de la clientèle, la marge de profit et le risque. Le modèle proposé est un calculateur spécialisé intégrant la maison de la qualité (HOQ), la technique d'analyse fonctionnelle de système (diagramme FAST), l'analyse du risque, l'analyse de la complexité du produit et l'analyse de la propagation de la modification. Il est ainsi possible de fournir une vue d'ensemble du processus de conception du produit allant des attributs du produit et du risque de la conception jusqu'aux coûts et aux efforts requis.L'analyse des diverses solutions de conception est effectuée en comparant les mesures de performance obtenues avec celles qui sont associées à la conception initiale. Le système permet de recalculer les mesures de performance lorsque des modifications techniques sont apportées dans le cadre de la création de nouvelles solutions de conception. Le système fournit alors, par le biais d'une analyse comparative, une estimation de l'impact de la modification sur les ressources requises et les avantages escomptés. À l'aide de ces fonctionnalités, l'outil proposé vise à aider les chefs de projet à trouver la solution de conception optimale.Le principal objectif du modèle proposé est d'augmenter la connaissance du produit dès les étapes préliminaires de la conception afin d'appuyer le processus de prise de décision des chefs de projet et des ingénieurs de conception. Cet objectif est réalisé par la visualisation des impacts d'une modification technique. Dans ce mémoire, le système d'aide à la décision (SAD) proposé est décrit de manière détaillée et illustré par un exemple simple, celui d'un contenant isotherme.

Texte intégralThe following thesis work has been conducted as a case study at GN Hearing and a literature study, where different theoretical areas are used as the basis for the workshop that was held at the company. In addition, structured observations, surveys and interviews have been conducted to provide as comprehensive a picture of the current situation as possible. The study addresses the topic of value stream mapping and aims at substantializing GN Hearing's return flow for a particular product family. The work leads to an analysis that, with the support of the theory, presents improvement proposals and tools, as well as a future desired value flow. The thesis describes the flow from a point of view that has Lean, process orientation and value creation as a basis, which enabled the development of a new, more efficient flow with less waste. The questions that pervade the study treats mapping the value flow to identify waste and distinguishing value creation activities from non-value creation within GN Hearing's ITE return flow. The results of the value stream mapping shows that, of all identified activities, non-value adding activities are a full 99% of the total. Non-value creating activities were found primarily in the form of waiting and variation. With the proposed improvements, a new flow is emerged, where activities considered non-value adding are reduced by about 50%. In addition, other tools for further continuous improvements were also presented.

Power system infrastrcutures are changing rapidly from analog arrangements to entirely digital methods. This offers numeous benefits such as increased efficiency, lower cost, higher accuracy, and even improved safety. However, digital implementations do not have an as proven track record as compared to conventional practices, leading to concerns about their reliaiblity. This research tests the performance an en entirely digital protection scheme by using various hardware components. The results are analyzed and show that the novel scheme operates correctly, albeit with a slight delay as compared to traditional methods.

Texte intégralThis thesis has been performed as a part of the Bachelor degree in Industrial Engineering and Management at the School of Engineering in Jönköping. The thesis is written on behalf of Pallco AB, which is an engineering company that performs subcontracting, surface treatment, and assembly of components, mainly in steel and aluminium. The thesis focuses on identifying and analyzing the customer order fulfillment process of three customers at Pallco AB.
The main objective of the thesis is to distinguish time differences in the company’s administrative work for each of the three customers. Furthermore, Lean thinking is following as a thread through the whole thesis. A comprehensive survey has been made to gain a greater understanding of the company’s processes and order flow. A deeper analysis of the administrative processes has then been made by value stream mapping and analysis, which shows how Lean can be applied through administration. Suggestions of key performance indicators linked to Lean are associated with the order flow. The information of the thesis has been gained through interviews with relevant personnel at Pallco AB.
The current situation for Pallco AB is that they carry out an unspecified amount of work and service for different customers without taking extra cost. The analysis and the result of the thesis show that there is one specific customer who is often given priority. Special and urgent orders are accepted, and often given priority over others. The result shows that about 45 percent of the identified administrative time of the customer order fulfillment process is applied on this priority customer. Characteristic examples of the other customers are that duplication of work is performed by Pallco AB in terms of reporting information to the customer’s own business information sys- tem.
Improvement and suggestions for further work of the customer order fulfillment process are given as a result of the thesis. The main suggestions are to further identify the extra service for the priority customer, and to further work with Lean administration through value stream mapping and key performance indicators linked to Lean.
Examensarbetet har utförts som en del av högskoleingenjörsutbildningen Industriell organisation och ekonomi, logistik och ledning, vid Tekniska Högskolan i Jönköping. Rapporten är skriven på uppdrag av Pallco AB. Företaget är ett verkstadsföretag som utför legotillverkning, ytbehandling och montering av komponenter, främst i stål och aluminium. Examensarbetet har sitt fokus på att kartlägga och analysera Pallco AB:s kundorderuppfyllelseprocess för tre stora kundgrupper.
Att urskilja tidsskillnader i företagets administrativa arbete för respektive kundgrupp och vad dessa beror på är det huvudsakliga målet med arbetet. Dessutom följer lean-tänket med som en röd tråd genom hela examensarbetet. Större förståelse för företagets processer gällande ordergången har fåtts genom att en övergripande kartläggning har gjorts. Därefter har en djupare analys av de administrativa processerna genomförts med hjälp av värdeflödeskartläggning och analys, vilket visar på hur lean i administrationen kan tillämpas. Även förslag på lean-nyckeltal kopplat till orderflödet har givits. Examensarbetets information har främst erhållits genom intervjuer med berörd personal på Pallco AB.
I dagsläget lägger Pallco AB ner varierande mängd arbete och service på olika kunder utan att ta något extra betalt för det. Examensarbetets analys och resultat visar att det specifikt är en kund som prioriteras, mycket genom att special- och akutorder accepteras samt att kundens order ofta ges förtur. Resultatet visar att omkring 45% av den kartlagda administrativa tiden i kundorderuppfyllelseprocessen läggs på denna kund. För andra kunder är utmärkande drag exempelvis att dubbelarbete utförs av Pallco AB i form av rapportering av information i kundens affärssystem.
I resultatet ges dessutom förbättringsförslag samt förslag på fortsatt arbete för kundorderuppfyllelseprocessen. De främsta förslagen handlar om att vidare kartlägga den prioriterade kundens extra service samt att arbeta vidare med lean administration genom fortsatt arbete med värdeflödeskartläggning och lean-nyckeltal.

Texte intégralInnovation represents a vital process for companies to insure their development. Several actions and new strategies are implemented by companies to increase their performances and so face market requirements. A good knowledge of both the innovation process and the company organization is necessary to allow the top management to manage them effectively and to adapt them to the challenges and the changes in their environment. Consequently, it is important for the companies to have tools and methods to measure continuously their innovation activities. The objective of our research is to suggest a framework to measure innovation capacities of companies based on a set of fifteen innovation practices, each practice is subdivided into several criteria which are directly observable phenomena in company. The methodological approach is based on the multicriteria aggregation method and the use of statistical notion of value-test to propose a typology of innovative companies of four classes (proactive, preactive, reactive and passive). An experimental study was led on a sample group of twenty French industrial companies. A software implementing our methodological proposition was developed. It allows to analyze and to estimate the innovative processes of a set of companies, to allocate them to a class and to give them recommendations for the relevant actions to follow to increase their innovation potential. This research proposes an effective decision-aid tool that helps in the innovation management

This thesis shows that lean principles that have been successfully applied in manufacturing can also be successfully applied across an entire enterprise. Established lean principles and lessons learned in lean manufacturing environments are applied across an automotive fuel system enterprise. This enterprise includes all major activities used in developing and delivering fuel systems to customers from the initiation of the systems concept to final production manufacturing. The value of the enterprise's product (fuel systems) is specified in terms of enterprise customers. The value stream of the fuel system enterprise is identified and analyzed using process mapping, input/output information flow diagrams, and other techniques. Major issues in terms of waiting time, rework time, and excessive need for validation are identified using these techniques. Countermeasures against these issues are offered to facilitate a transition to a leaner state. The goal is to develop a systemic understanding of the fuel system enterprise such that lean principles and tools can be applied to its processes to improve efficiency, throughput, and value for customers. Recommendations for further study are also listed in an effort to pursue perfection by continuously improving the lean enterprise. Finally, a transition to lean implementation plan is outlined.

Texte intégralBeans are an important source of protein, starch, vitamins, minerals and fiber in the Brazilian diet. The protein digestibility and mineral bioavailability, however, may be affected by the presence of anti-nutritional factors. Currently, germination has been used as an alternative for the removal or inactivation of these components, thus improving nutritional qualities of beans. This study aimed to study the effect of gamma irradiation and germination on the nutritional aspects of beans. The carioca bean variety was used, cultivar pérola, obtained from producers of Goiás state Brazil. The grains were irradiated in a Cobalt60 source, Gammacell type, at a dose rate of 0.456 kGy/ hour and soon after, they were germinated in room temperature and light during 72 and 96 hours. Then, the samples were frozen and lyophilized. The centesimal composition indicated that germination caused an increase in moisture, protein and soluble and insoluble fiber. However, it showed a decrease in ash, lipids and carbohydrates contents. Irradiation did not influence concentrations of the chemical composition of the samples. Microbiological tests of the sample germinated in 72 and 96 showed growth of coliforms, below acceptable levels. Salmonella and fecal coliforms in the samples showed no growth. The sensory analysis showed low rejection of the germinated beans. The phytic acid showed a reduction in its content after germination, but not significantly compared to the control sample. The amounts of tannins, after germination in 72 hours, were not detected in the samples. A reduction in trypsin inhibitor content and total phenolic content between samples was observed with the effect of germination. In the germinated plants, the hemagglutinin content decreased and digestibility increased. Flavonoids were not detected in any sample. Chlorophyll and total carotenoids showed an increase after seed germination. The highest antioxidant activity was found for the beans germinated in 96 hours being 78% and 33% for ABTS and DPPH methods, respectively. The mineral composition was not affected by irradiation treatment, but the germination process was. The in vitro availability of iron, calcium, magnesium and zinc, in spite of the germination and irradiation, the control bean did not show a significant difference in the samples germinated was no increase in values. The availability of magnesium decreased with the germination process. After germination was increased the levels of riboflavin and vitamin B6, but decreased the amount of thiamin. The irradiation process did not compromise the nutritional value of vitamins in the beans. Thus, we conclude that germination improves the nutritional quality of the grain should be nurtured their consumption in the Brasilian diet.

Resumo: Os problemas relacionados com a prática tradicional de redução de custos na construção civil e a necessidade de aumentar a competitividade de empresas do setor de real estate nortearam essa pesquisa. Neste sentido, o custeio-meta é uma abordagem promissora para melhorar a competitividade de empresas garantindo que os produtos lançados no mercado não comprometam a margem de lucro da empresa nem a entrega de valor para os clientes. No entanto, há uma escassez de pesquisas visando apoiar as organizações do setor imobiliário que desejam implementar de forma gradual os princípios do custeio-meta no processo de desenvolvimento de produtos imobiliários destinados à venda. Diante disso, o principal objetivo da pesquisa foi propor diretrizes para introdução do custeio-meta no processo de desenvolvimento de produtos imobiliários destinados à venda. A design science foi o método de pesquisa utilizado. A pesquisa foi dividida em três fases: incubação da solução, refinamento da solução e explanação. As diretrizes propostas estão relacionadas as três principais seções do processo do custeio-meta: custeio orientado ao mercado, custeio-meta no nível de produto e custeio-meta no nível de componente.
Abstract: The problems associated with the traditional practice of reducing costs in construction and the need to increase business competitiveness in the real estate sector guided this research. In this sense, the target costing is a promising approach to improving the competitiveness of companies by ensuring that products launched on the market do not jeopardize the company's profit margin or the value delivery to customers. However, there is little research to support the real estate industry organizations wishing to implement gradually the target costing principles in real estate product development process. Thus, the main objective of the research was to propose guidelines for introduction of target costing in the real estate products development process. Design science was the research method applied. The research was divided into three phases: solution incubation, solution refinement and explanation. The proposed guidelines are related to the three main sections of target costing process: market-driven costing, product-level target costing and component-level target costing

Texte intégralThe development of fuel efficient internal combustion engines (ICE)have resulted in a variety of different solutions. One of those are the variable valve timing and an implemenation of such is the Continuous Variable Cam Phasing (CVCP). This thesis have used a simulation package, psPack, for the simulation of the gas exchange process for an ICE with CVCP. The purpose of the simulations was to investigate what kind of design parameters, e.g. the length of an intake pipe or the duration of combustion, that were significant for the gas exchange process with the alternation of intake pressure, engine speed and valve setting. The parameters that showed a vast impact were those who affected the amount of residual gas and the temperature of the air charge. Furthermore a validation was made between simulation data acquired from psPack and measured data provided in Heywood (1988). The validation showed that for the general behaviour the simulation results from psPack corresponded well to the measured data.

Resumo: Atualmente há uma grande preocupação mundial com o esgotamento e o alto custo de exploração das reservas de combustíveis fósseis e, portanto, mais do que nunca, é necessário o aprofundamento do estudo e aproveitamento de fontes alternativas que possam ser utilizadas com eficiência energética, preços adequados e com baixo impacto ambiental. De acordo com estas premissas, o biodiesel é um combustível com boas perspectivas de atender uma demanda crescente, pois além de substituir o óleo diesel, pode ser obtido a partir de várias fontes primárias de origem animal e vegetal. O Brasil se destaca na utilização das fontes alternativas de energia com o uso do etanol e, nos últimos anos vem incentivando a ampliação de sua matriz energética a partir das fontes alternativas, na qual o biodiesel passa a ter uma importância estratégica dentro da área de agronegócios. O biodiesel é um combustível que pode substituir o diesel, que é um derivado do petróleo; é um éster produzido na reação de transesterificação de óleos vegetais, goduras animais que, na presença de um álcool, metanol ou etanol, e um catalisador, são convertidos em ácidos graxos e, resultam, em ésteres com glicerol como subproduto. Com o avanço da utilização destes biocombustíveis são necessárias pesquisas que visam melhorar a qualidade e viabilidade técnica dos mesmos, sendo que, o balanço energético é um dos parâmetros mais adequado para definir a viabilidade técnica, pois estabelece a relação entre o total de energia contida no combustível e aquela investida em todo o processo de produção.

Abstract: Nowadays there is a great global concern with the depletion and the high cost of fossil fuel reserves exploitation, more than ever, it is necessary to make a profound study and take advantage of alternative sources that can be used with energy efficiency with an appropriate pricing and with low environmental impact. Under these assumptions, biodiesel is a fuel with good prospects of meeting a growing demand, as well as being a replacement of diesel oil, can be obtained from several primary sources of animal and plant origin. Brazil, which has highlighted in use of alternative energy sources with the use of ethanol and, in recent years, has been encouraging the expansion of its energy matrix in which the biodiesel will have a strategic importance within the agrobusiness area. Biodiesel is a fuel that can replace the diesel,that is a petroleum derivative. It is an ester, produced in the transesterification reaction of vegetable oils and animal greases, that in the presence of an alcohol like methanol or ethanol with an additional catalyst, are converted into fatty acids and result in esters with glycerol as subproducts. The advancement in use of biofuels, some researchs needed improve the quality and feasibility and that energetic balance is one of the most appropriate parameters to define the technical feasibility, since settle the same relationship between of total energy in the biofuel and the total energy invested in the whole production process. The objective of this study was to estimate the final energy balance for the process biodiesel production from oil chicken waste. The energy balance estimation was quantified in calorific value according the energy expenditure by calorimetric bomb method.

Texte intégralCentred around a discursive perspective - the discourse analysis - this research has as theoretical focus the constitution/identity of the discursive formations and controversial interdiscursiviness relations. Furthermore, inquiries such as the discourse analysis interdisciplinary dimensions and the conception of the political discourse analysis were also observed. In order to verify the theoretical focus , we have chosen as corpus the written discourses diversities that confronted during Companhia Vale do Rio Doce - CVRD privatization process. CVRD is the largest mining company in the world. Its privatization process did not happen in a peaceful and consensual way, but with exhaustive confrontational debates between government and civil society. This confront led to a question: as the process has occurred with exhaustive debates, it happened to have a democratic appearance, nevertheless, the \"victorious\" discourse is the one identified with the governmental discourse, that proposes and effects the privatization. If there were strategies of how to conduct the process, how is the appearance of the persuasive \"victorious\" discourse characterized, convincing or simply hegemonic? On the whole, this question, has led to the following objectives: confront the arguments verifying the strength of one in relation to the other; verify the refutation mechanism and how the identities and discursive images are built. The underlying question is to understand, how the political phenomena are settled or if they are established discursively in a space and power confluence not always liable to clarity and visibility.

Texte intégralThis master work presents the results of the research of the education systems of Lithuania, the Russian Federation, Norway, Sweden and Latvia (on reading literary and information by describing them, giving reading curricula (planning and realizing levels). The criteria established for comparison and evaluation of the education systems with regard to reading and writing in native language allow to analyse, compare and evaluate the education systems of reading and writing in native language at the planned achievement level and are easy to apply for other studies. Following the analysis of goals and objectives in teaching reading and writing in native language in primary schools of Lithuania, Sweden, Norway, Latvia and the Russian Federation at the aspects of the school system aimed at formation of reading and writing context, knowledge and skills, general reading and writing abilities as well as attitudes and values, we can see that the major attention to teaching reading and writing is given by the Russian Federation (it devotes about 50 % of time to teaching language in the first form, 42 % of time in the second, third and fourth forms is devoted to the language and 30 % to reading). Given 19 lessons per week, it makes up about 9.5 lessons per week in the first form and about 7.98 lessons per week in the second-fourth forms, while in Lithuania and Norway this number accounts for 5. 95 and 5.94, respectively.

Texte intégralSocial hållbarhet är en av tre dimensioner i begreppet hållbarhet och ses som den svagaste pelaren för hållbar utveckling. Tidigare litteratur drar slutsatsen att social hållbarhet är ett svårt begrepp att definiera och uppnå. Därför har den sociala dimensionen inte behandlats i samma utsträckning och har ofta undvikits i forskning och praktik. Däremot har betydelsen av den sociala dimensionen av hållbar utveckling uppmärksammats av både den privata och den offentliga sektorn under det senaste decenniet. Den sociala aspekten kräver mer uppmärksamhet och det är viktigt att fastställa de sociala hållbarhetsprocesser som bör integreras under planeringsfasen i bostadsutvecklingsprojekt. Syftet med denna studie är att bidra med kunskap om hur social hållbarhet kan hanteras i bostadsbranschen och inom de vetenskapliga områdena stadsplanering och rojektutveckling. Genom att, från både bostadsutvecklarens och kommunens perspektiv, djupare undersöka hur sociala hållbarhetsaspekter behandlas i dag, hur samarbete kring dessa aspekter fungerar, vilka värden ett fokus på sociala aspekter kan skapa för båda parter samt önskemål för framtiden, syftar studien också till att ge en rekommendation för hur bostadsutvecklare kan förbättra sin arbetsprocess. Fyra projekt som ligger både i Stockholm och Göteborg har använts som underlag till empirin i denna undersökning Empirisk information har samlats in, främst genom intervjuer, men också utifrån befintliga sociala hållbarhetsverktyg. Intervjuerna genomfördes med representanter från JM AB och kommunerna Stockholm och Göteborg. Studien har identifierat att konkreta verktyg, samarbete, tydliga mål och en förståelse för varandras syften och mål är avgörande för en god arbetsprocess beträffande social hållbarhet. En rekommenderad arbetsprocess har utvecklats i syfte till att hjälpa bostadsutvecklare att adressera social hållbarhet i bostadsprojekt. De identifierade stegen i rekommendationen ger en förståelse för hur bostadsutvecklare ska arbeta med social hållbarhet internt och i samarbete med kommunen. Genom att arbeta systematiskt med social hållbarhet i bostadsutveckling, visar studien att bostadsutvecklare kan bli mer attraktiva i kommunens ögon och därmed få en konkurrensfördel gentemot sina konkurrenter, samt öka möjligheten att skapa gemensamma värden.
