Full textLundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.
On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions:
- Which wastes can be found with help from a value stream mapping (VSM)?
- In what way can these wastes be reduced and how can these reductions contribute to an improved production?
VSM is the method used to find the non value-added wastes. In the context of Lean production this is a reliable method because it shows in a good way the wastes in a manufacturing process. The VSM was performed on the family of food bin, which is one of the company’s more recurring products.
During the analysis of the value stream we found several wastes in the manufacturing process. All categories of non value-added wastes are represented. Examples of identified wastes are unnecessary transportation and working movement. The limited access to operators who have the right competence and who are allowed to process the food bins, is in our opinion one of the factors that generate most of the non value-added wastes.
Several action proposals were worked out and a conclusion is that one action proposal can generate a reduction of different kind of wastes. The action proposals that can reduce the most of the non value-added wastes are a change of the layout and competence building. This means that one action proposal can reduce or eliminate several wastes at the same time.
Lundbergs Plåt AB är ett mindre företag i Jönköping vars huvudsysselsättning är plåtbearbetning. På senare tid har ett intresse väckts för att undersöka vad Lean skulle kunna ge deras företag.
Utifrån ovanstående formulerades syftet att finna och minska de så kallade ”sju slöserierna + ett” som finns beskrivna inom Lean. Utifrån detta preciserades två frågeställningar:
- Vilka slöserier går att urskilja med hjälp av en värdeflödesanalys?
- På vilket sätt kan dessa slöserier minskas och bidra till en förbättrad produktion?
Metoden som användes i sökandet efter slöserierna är en värdeflödesanalys,som är en väl beprövad metod i Lean-sammanhang. Detta för att den på ett bra sätt för upp slöserierna i ett tillverkningsflöde till ytan.
Värdeflödesanalysen utfördes på produktfamiljen livsmedelsbehållare som är en av företagets mer frekventa produkter.
Under analysen av värdeflödet fann vi ett flertal slöserier i tillverkningsflödet. Samtliga kategorier av de ”sju slöserierna + ett” finns representerade. De största slöserierna är enligt vår bedömning de som uppkommer till följd av företagets begränsade tillgång på operatörer som kan och tillåts bearbeta behållarna. Andra identifierade slöserier är onödiga transporter och arbetsmoment som sker i tillverkningen.
Förbättringsförslagen arbetades fram utifrån syftet att minska och eliminera funna slöserier. De åtgärder som kan minska flest antal slöserier är layoutändring av produktion och flöde samt kompetensutveckling av personalen. Detta innebär att ett och samma åtgärdsförslag kan generera flera minskade eller eliminerade slöserier.

Full textOutokumpus Stainless AB is a global manufacturer of stainless steel. In Outokumpus steelwork in Avesta, the heat rolling unit has problems with the risk of personal injury when handling defective pieces of sheet metal after steckel rolling. This handling of defective sheets is currently manually executed by operators, where high-lift risks with defective plates have been given high risk points in Outokumpu's risk assessment.Outokumpu as a client wants to investigate the possibility of developing a conceptual proposal to reduce the risk of personal injury in handling defective sheet to be disposed of from the production line. The concept should also reduce the cycle time of the handling and be adapted to existing construction.This report presents a requirement specification and a selection of concepts evaluated based on requirements specification and soft criterias. After the evaluation, the concept with the best evaluation points has been worked on to set dimensions and analyze the concept.The result of the conceptual development became a concept that, with a beamwork, lifts the defective plate directly above the rolling path using four hydraulic cylinders. In the raised position, the plate is on the beamwork and is pushed off the rolling roller directly onto a bolster with a ruler driven by two hydraulic cylinders. The concept meets the requirements of the requirement specification and reduces the risk in Outokumpu's risk assessment.Keywords: Risk

Full textProduct concept for a double-reel for sheet metal – For a more effective process in steel-industry in handling sheet metal, is a project as implemented at Karlstad university in cooperation with Camatec Industriteknik AB and is an examination of the engineering education ’Innovationsteknik och Design’. The project is about to develop a product concept for a double-reel. Camatec Industriteknik AB is a consulting company and works in a close relationship with the company Camcoil Systems AB. Camcoil Systems AB manufactures single-reel’s, machines as used in the steel industry in handling thin sheet, strip steel. Camcoil Systems AB has expressed the desire to in the future be a double-reel manufacture. By this project Camcoil Systems AB wants to build a base to develop the produced concept. In order to develop a sustainable product concept there are four major categories in this project which are investigated; Market, technology, design and budget. Security is something that is also taken into consideration in the project. The design-process is applied in order to achieve the goal. A feasibility study is the basis for the entire project, where all these four main categories, scientific theories regarding to perception, colour theory, product development and design laws are treated. The produced concept is built upon a clean design in which the functions and the design are synchronized towards each other. In that way, they reinforce each other. There are also a sustainable technology and a good security. At the same time the costs are not too high. With the produced concept, there is a foundation which enables a further development for Camcoil Systems AB to be a potential entrant for the market in producing double-reels.

Full textProjektgruppen har genom ett samarbete med Plåtslageriernas Riksförbund identifierat de ergonomiska behov som finns inom takbranschen. Många takarbetare har förslitningsskador på grund av den dåliga arbetsställning de utsätts för varje dag. Detta är främst det oundvikliga knäståendet som krävs för att över huvudtaget nå de objekt som ska bearbetas.
Projektgruppen har därför tagit fram en helt ny typ av hjälpmedel som inte bara erbjuder en bättre arbetsmiljö utan även förenklar arbetet och spar tid. Projektgruppen upptäckte även att tidsbesparingen var av yttersta vikt för att en takarbetare ska vilja använda en ergonomiprodukt.
Resultatet av projektet är Expresser ES, en produkt som främjar ett längre aktivt arbetsliv för takarbetare. Projektgruppen har under sitt examensarbete på Utvecklingsingenjörsprogrammet vid Högskolan i Halmstad utvecklat något takbranschen länge behövt. Man är både stolt och nöjd över att ha lyckats ta projektet så långt som man gjort under en så kort tid.
The project group has together with Plåtslageriernas Riksförbund identified the need of ergonomical products in the roofing business. Many roofers have repetitive strain injuries due to the bad working posture they face in their everyday work. It is first and foremost the inevitable kneeling which is required to be able to reach the objects that is going to be processed.
That is why the project group has developed a new type of aid that not only offers a better working environment but also makes the work easier and saves time. The project group also discovered that the time saving is of great importance if the roofers are going to use an ergonomical product at all.
The result of this project is Expresser ES, a product that promotes a longer active working life for roofers. The project group has during their bachelor´s thesis at Utvecklingsingenjörsprogrammet at Högskolan i Halmstad developed something that the roofing business has been in need of for a long time. One is both proud and content with the extent of the project compared with the short time span it has been carried out within.

Full textThis report describes the development process of a pipe clamp used on exhaust system for cars. It is made based on the manufacturers desire to improve and make the clamp easier to manufacture and to reduce its price to their customers. This should be done either by manufacturing the clamp in one piece without an expensive and work intensive welding process, or by generating ideas of how to develop a brand new type of clamp. Investigating the market for similar products was done to eliminate intrusion of other manufacturers’ patents but also to generate ideas. Making drawings of the many ideas gave a concept of three concepts called existing clamp in one piece, existing clamp by several pieces and innovation solutions. Some of these ideas were investigated further and were 3D modelled in pro-engineer and necessary drawing files were made to be used in the manufacturing of several prototypes. One of the solutions resulted in a prototype that was manufactured by handmade tools and the results of the tests was very positive. The clamp was strong enough to join the pipes together very well without breaking. It was manufactured in one piece and formed in five steps without any welding operations instead of the seven steps, including welding, that is used on the clamp today. The prototype requires 25 % more material and most of it is scrap from the cutting operation.

Full textCIDAN Machinery Sweden AB, originally AB Göteneds Mekaniska Verkstad, has manufactured machines for sheet metal processing and parts for industry that are equipped with various control panels or control boxes. The company now wants to explore possibilities for improvement, both in cost as function and design regarding these control boxes. The aim of the degree project is to explore the possibility of designing a control box that will replace three existing models and lead to a more economically viable product with improvements in areas such as manufacturing, assembly, usability and sustainable development. The controlbox also has the requirement to use the existing electronics. During the prestudy, Quality Function Deployment was implemented as a method of working with customer and quality-oriented design. Steps included observations and interviews with the target group, analysis of existing design with a failure modes and effects analysis and a study of alternative materials to identify and weigh customer needs that can be linked to technical specifications. The information gathered resulted in a requirement specification that the new product would meet. Concept development initiated with an analysis of the company's product identity. Subsequently, the control box was divided into partial functions and suggestions for sub-solutions were generated. A morphological matrix was used to produce six complete solutions that were then evaluated and screened depending on how well they met the needs. Finally, one of two further developed concepts was considered to have the greatest potential and would best meet the specification. The result was a control box that fulfills the requirements and replaces two of three existing models, with improvements in environment, cost and productidentity. A full scale prototype was finally made in collaboration with the company which showed that the final concept could be manufactured.

Full textApproximately 40 years since the completion of the Swedish Million Programme, renovation and rebuilding of the real estates are highly prioritized. White Architects has been assigned a renovation and rebuilding project in Northern Stockholm which encompasses two real estates completed during the Million Programme. This thesis examines the recycling of existing sheet metal facades on the mentioned properties. White Architects want to explore the possibilities of using the original material to produce new facades through recycling. The aim is to present the material’s lifecycle, while considering environmental conditions, in connection to the Million Programme. To answer the question at hand, a sample of the sheeting has been investigated in order to identify the material. The material has been determined as aluminum through the identification of the plate’s density. A number of companies, which have been involved in the recycling process of going from plain sheet to perforated sheet, have been contacted. This thesis presents the different stakeholders and stages in the recycling process. The idea is based on Cradle to Cradle which is a theory developed by the German chemist Michael Braungart and American architect William McDonough. The theory's basic concept is based on eliminating waste by seeing waste as fuel for technological or biological processes. Aluminium and other metals are examples of materials that can be used in the technological cycle. With today's recycling processes they lose their value and cannot be reused for the same purposes. Recycling aluminum saves up to as much as 95% of the energy which is consumed in the primary production. When the Cradle to Cradle theory had yet to have any significant impact in Sweden, several obstacles were encountered. This report shows that there is no smelter in Sweden which separates the different aluminum alloys. All aluminum recycled in Sweden will end up as castings. To achieve the desired results and demonstrate the real possibility of the project, a scrap based smelting and rolling mill in Norway was contacted. To summarize, the project is entirely feasible both in theory and in practice, as long as the right collaboration partners are involved.

Full textIn this master thesis the strength and stiffness of glulam beams is being investigated and how these parameters change when you reinforce the beams with steel. A literature review has been conducted to establish what’s been done in this area previously, regarding reinforcements of glulam beams. Glulam beams got a greater solidity compared to regular construction timber. When dimensioning beams, a certain maximum deflection is allowed, that depends on the beam's span. A reinforcement with steel, that has higher strength properties, can mean that you can handle the requirements with a smaller cross section. Even the stiffness of the beam could be raised, which in turn causes the beam's frequency to be raised. In this particular study three different types of steel reinforcement has been investigated. The steel plates were glued together with the glulam beams. The beams were placed upon heaps and a point load stressed the beam at the center until the beam fractured. The reinforced beam showed an increase in strength between 23,9-30,7 % and an increase in stiffness between 13,2-37,6 %. With a different type of steel, with higher solidity, the increases would probably been greater.

Full textAbstract This thesis documents a bachelor’s degree project for the engineering programme in Innovation Technology and Design, spring semester 2018 at Karlstad University. The project has been carried out in accordance with conventional product development process, in an assignment to design a paper bin for SPAZA; a Swedish company that provides elegant products for spa and hotel environments. All products in the assortment are within the SPAZA material and manufacturing specification: laser cut, bent and powder coated stainless steel sheet. The purpose of the project is to apply knowledge acquired from the engineering programme and, with a scientific basis, design a paper bin that considers the needs in all the different stages of its life cycle. This without compromising style or aesthetic expression. A pre-study identified the needs in manufacturing, shipping, assembly and use by hotel guests and cleaning staff. These needs were then formulated openly as primary and secondary requirements, and together with what had already been specified by the outsourcer, a product specification was formed, which was later used in idea generation. Idea generation produced a lot of ideas for forms and functions. These were combined, and together they formed concepts that were developed further in work with models. Recognized methods for screening were then used to determine which concepts that were of value to present to the outsourcer, and during a conceptual meeting a decision was made on which concept to realize. A final concept, Concept 4 as it was called, derives from an idea for function about using the sheet metal’s flexing material properties to hold up the bag. The concept meets the needs in the various life cycle stages with a total of 30 out of 31 fulfilled requirements listed in the product specification. A CAD model of Concept 4 was sent to CNC Plåt in Västervik for prototype manufacturing. The prototype was evaluated and adjusted in accordance with identified improvements in forms or function, and with a second version of the CAD model having been delivered to the outsourcer, the goal of the assignment was achieved. The project is finished, and the paper bin is one step closer to production.

Full textBeckholmen is an island, not always carefully threated by history. To fulfill new purposes and functions, the island has always been altered for new needs. Today is Beckholmen strongly marked by this treatment, and has transformed to be known as a very sensitive and fragile place, both in nature and exposure for Stockholm. Strong wills with different ambitions want to decide about Beckholmen’s future. There are different approaches amongst for example the city, Stadsbyggnadskontoret and Djurgårdsförvaltningen, about what qualities are most worth embracing. We have been asked to draw a ship yard for reparations at Beckholmen. The most natural approach for me was to let the island’s eventful history continue in to the future. Beckholmen is a unique possibility to build a brand new industrial building in the heart of Stockholm, and let it be shown that the city is carried by people who works. Why does an industry have to be deported to the suburbs, when it’s rather an indication of a living city? I purpose a permanent building at Beckholmen. Permanent to define the site with its volume, but with flexible spaces within. The flexibility makes the industry adaptable to changes, but with some fixed part to relate. The tower is partly for the balance of the volumes, but mainly for residence of the shipyard staff. Alike a lighthouse it stands there visible for south of Stockholm, without being ashamed for either itself, or what it contains.

Full textDuring the second semester of 2013, product design engineering students Stefan Erlandsson and Louise Andersson have been involved in a project in cooperation with entrepreneur Lars Willebrand. The main objective of this project has been to develop a lifting tool for sheet materials. The lifting tool is one of four different products developed by Lars Willebrand. The line of products also includes an overhead crane, a slewing crane and a storage drawer for metal sheets, which are already fully developed and ready for production. The purpose of this lifting tool is to be used along with the storage drawer which means that is has to be optimised for lifting sheet materials from different heights. This means that the lifting tool has to be designed with regards to the users working postures. Human factors such as ergonomics have to be taken into account as well. The initial part of the project is a pre-study with focus on ergonomics and human factors. This pre-study included a study in relevant literature, contact with a manufacturing company and an analysis of the possible competitor’s lifting tools. The results from the pre-study have further been used to define the specification of requirements, which is the foundation for the concept development. The concept development has undergone a number of different phases. All of the lifting tool’s main functions were broken down and developed individually. The functions were as follows; adjustment of the suction cups, lifting from different heights and handling. The most suitable solution for each main function were chosen and assembled into one final concept. The final concept has been analysed and further developed in order to please the employer and the users of the lifting tool. Some details in the design have been changed in order to ease the manufacturing of the lifting tool. To ensure that the final concept matches the specification of requirements, strength calculations and FEM analysis have been made and anthropometrical measurements have been taken into account. The final chapters include a discussion and recommendations for further development of the lifting tool.

Tra?amos ent?o uma cartografia do close, mostrando como a cria??o de espa?os e performances acontecem na cena natalense entre os flashs capturados nos eventos e como os closes s?o arrastados para outros ambientes da cidade.
Our research program runs through the musicality circuit in Galp?o29, which is located in the neighborhood of Ribeira, in Natal-RN. From this location we seek to draw a cartography of musicality spaces. In Natal?s night opened up spaces for action of collective organizers of parties, inviting young people to attend the events present at the festive agenda of Galp?o29. The festivities opened environments, and in their midst, invited the participants to the action. The notion of close, in our thesis, seeks to present the form of relationship between bodies with the environments present in our city. On those parties we could find young people pouring their desires in their own bodies, microphones, announced flyers of events, calls for consideration and participation of performances. We found DJs and bands who composed musical productions and spread it in the costumes, to act on stage. The public were faced with participants acting in the scene by creating their own closes. We questioned the creation of work spaces where momentary freedoms are realized, where the body drunk to music and moves of everyday overcodings of city?s life. The creation of festive plateaus make up micropolitical effects on the city?s scene, through the celebration of life and composition of musicality that are expressed in their minor effects. Then we draw a cartography of close, showing how the creation of spaces and performances take place in Natal?s scene between the flashes captured in the events and how the closes are dragged to other city environments.

Full textThis thesis is focused on the improvement of an existing implementation of a waveform visualizer. The problem area handled in this work has its focus on how to reduce the number of points to be plotted. The given waveform visualizer was extended by the use of two additional algorithms. First, a Level Of Detail (LOD) algorithm that gives the subset of points that are necessary to plot the waveform in the current zoom level. Second, a straight line identification algorithm to find a series of points aligned in a straight line, only leaving the end points and then drawing a line between them. These two optimizations are the main focus of this work.Additionally, an exporting functionality was implemented to export the plot data into several different data formats. Also some improvements of zooming, panning, some GUI design, and a new drag and drop functionality was constructed.

Full textI detta examensarbete studeras hur de magnetiska egenskaperna hos SiFe-plat paverkas av skarning och svetsning. Permeabilitet och jarnforlustdensitet undersoks eftersom de ar kritiska variabler for elektriska maskiners prestanda. De magnetiska matningarna genomfordes pa en Epstein ram med en odesfrekvens pa 50, 100 och 200 Hz, enligt IEC 404-2. E ekterna av mekanisk skarning med giljotin samt skarning med ber- och CO2-laser studerades. Inverkan av olika berlaserinstallningar undersoktes ocksa genom att variera gastrycket, skarhastigheten samt frekvensen och e ekten av laserstralen. For att oka skare ekten inkluderades Epsteinremsor med ytterligare 1, 2 och 3 langsgaende skarsnitt. Det visas att mekanisk skarning har en mindre paverkan pa de magnetiska egenskaperna hos materialet an vad laserskarning har. Matningar pa plat med 1.8% Si visar att da prov med tre extra langsgaende giljotinklipp anvands kan permeabiliteten reduceras med upp till 63% och jarnforlusterna kan oka med upp till 35%. Motsvarande resultat for laserskurna platar visar en permeabilitetsreduktion pa upp till 65% och en jarnforlustokning pa upp till 65%. Ur studien av de tva studerade skarprocesserna framkommer aven att tunnare plat paverkas mindre negativt an tjockare plat. Ett antal olika installningar har provats for att utreda hur olika parametrar paverkar e ekterna av laserskarning. Studien indikerar att skarning med hog e ekt och hog hastighet ger den minsta paverkan pa materialets magnetiska egenskaper. Vilket aven har en positiv inverkan pa produktiviteten vid laserskarning. Epsteinprover har aven utforts for att undersoka vilka e ekter som introduceras da SiFe-plat svetsas. Provstyckena bestod av remsor med en, tre, fem och 10 svetspunkter. Experimenten visar en jarnforlustokning med upp till 50% samt en permeabilitetsreduktion upp till 62% da platarna svetsats samman tva och tva. En modell for att studera e ekterna av de forandrade materialegenskaperna vid skarning pa en induktionsmotor utvecklas och implementeras i en FEM-baserad mjukvara. Resultaten tyder pa en jarnforlustokning med 30% da skare ekten orsakad av giljotin beaktas. Vid simulering av laserskuren plat kan denna okning vara sa stor som 50%. Det framkommer aven att laserskarningen kan reducera e ektfaktorn sa mycket som 2.6%.

Full textIn 1996 Burago and Zalgaller showed the following theorem: Theorem (Burago and Zalgaller): Let S be a polyhedral surface, then S admits an isometric PL embedding in E3. This theorem shows in particular that the Flat Square Torus admits an isometric PL embedding in E3. In 1997 Zalgaller constructs such an embedding of Flat Rectangular Torii into E3. In the first part of this work, we do show an isometric embedding du Flat Square Torus in E3. This first result is stated as follows: Theorem: There is an isometric PL embedding of the flat Square Torus with at most 48 points. We know that the minimal triangulation of the flat torus is the Moebius Torus M. The 1-skeleton of the Moebius Torus is the graph K7. We consider GE(M, T2) the set of all geodesic triangulations of T2 isomorphic to M modulo translations. In the second part of this work, we give a complete description of this set : - The configuration space GE(M, T2) is the disjoint union of 12 products of 6-simplex. We writte LT(E3) the set of lineal isometric embeddings of a triangulation T of T2 in E3, in the third part of this worg, we have the following result : - There is a 12-dimensional neighborhood N(S) of a 6-diensional set S such that for every T in E3, we have LT(E3)= Ø

Ou seja: tentaremos mostrar que, se a Teoria das Id?ias foi postulada para garantir a significa??o ling??stica, a linguagem, por sua vez, servir? como modelo para ajudar a mesma Teoria a superar seus problemas.

In the fall of 1934 Major General Smedley Butler, U.S.M.C. (ret.) testified before Congress that he had been approached by a representative of a cabal of wealthy Wall Street bankers, powerful industrial magnates, and shady political operatives to lead a fascist coup to overthrow the administration of President Franklin D. Roosevelt. Congress investigated Butler’s allegations of a conspiracy against the government and deemed them to be true. The American news media, however, was noticeably divided in the nature of their coverage of the congressional investigation. Previous historians have claimed that elements of the American news media were markedly sympathetic toward fascism in the United States during the 1930s. An analysis of the newspaper coverage of this investigation reveals a stark contrast between ways in which media outlets headed by individuals suspected of fascist sympathies portrayed the story as opposed to media outlets known to be editorially anti-fascist. These findings lend credence to previous historians’ claims about identifiably pro-fascist strains in the American media during the time in question.

Full textDurch die Anwendung der neu eingeführten Komplexitätsmaße können Chaos-Chaos-Übergänge in Herzschlagdaten vor dem Auftreten einer lebensbedrohlichen Herzrhythmusstörung festgestellt werden, was für die Entwicklung neuer Therapien dieser Herzrhythmusstörungen von Bedeutung sein könnte. In einem weiteren Beispiel, in dem EEG-Daten aus einem kognitiv orientierten Experiment untersucht werden, ermöglichen diese Komplexitätsmaße das Erkennen von spezifischen Reaktionen im Gehirn bereits in Einzeltests. Normalerweise können diese Reaktionen erst durch die Auswertung von vielen Einzeltests erkannt werden.
Mit der Hilfe von Cross Recurrence Plots wird die Existenz einer klimatischen Zirkulation, die der heutigen El Niño/ Southern Oscillation sehr ähnlich ist, im Nordwesten Argentiniens vor etwa 34000 Jahren nachgewiesen. Außerdem können mit Cross Recurrence Plots die Zeitskalen verschiedener Bohrlochdaten aufeinander abgeglichen werden. Diese Methode kann auch dazu genutzt werden, ein geologisches Profil mit Hilfe eines Referenzprofiles mit bekannter Zeitskala zu datieren. Weitere Beispiele aus den Gebieten der Molekularbiologie und der Spracherkennung unterstreichen das Potential dieser Methode.
In this work, different aspects and applications of the recurrence plot analysis are presented. First, a comprehensive overview of recurrence plots and their quantification possibilities is given. New measures of complexity are defined by using geometrical structures of recurrence plots. These measures are capable to find chaos-chaos transitions in processes. Furthermore, a bivariate extension to cross recurrence plots is studied. Cross recurrence plots exhibit characteristic structures which can be used for the study of differences between two processes or for the alignment and search for matching sequences of two data series. The selected applications of the introduced techniques to various kind of data demonstrate their ability. Analysis of recurrence plots can be adopted to the specific problem and thus opens a wide field of potential applications.
Regarding the quantification of recurrence plots, chaos-chaos transitions can be found in heart rate variability data before the onset of life threatening cardiac arrhythmias. This may be of importance for the therapy of such cardiac arrhythmias. The quantification of recurrence plots allows to study transitions in brain during cognitive experiments on the base of single trials. Traditionally, for the finding of these transitions the averaging of a collection of single trials is needed.
Using cross recurrence plots, the existence of an El Niño/Southern Oscillation-like oscillation is traced in northwestern Argentina 34,000 yrs. ago. In further applications to geological data, cross recurrence plots are used for time scale alignment of different borehole data and for dating a geological profile with a reference data set. Additional examples from molecular biology and speech recognition emphasize the suitability of cross recurrence plots.

Filmes finos de Pb0,91La0,09(Zr0,65Ti0,35)O3 (PLZT) foram preparados sobre substratos Pt/TiO2/SiO2/Si(100), usando um método químico baseado no processo Pechini, com objetivo de estudar a supressão da fase pirocloro e a estabilização da fase perovskita. Pós de PLZT preparados por reação do estado sólido foram utilizados como principal fonte de íons Pb2+, La2+, Zr4+ e Ti4+ pela dissolução em solução ácida. A obtenção de resinas poliméricas estáveis com diferentes excessos de chumbo foi possível preparando-se separadamente as resinas de PLZT e PbO seguido de posterior mistura e homogeneização à temperatura ambiente.

The story of Macbeth centers around revenge. World War I was started by an act of revenge. Even though these two stories are seemingly unrelated, humans use the same concept to draw meaning from them. Plot units, revenge included, are the common set of structures found in human narrative. They are the mistakes, the successes, the revenges and the Pyhrric victories. They are the basic building blocks of stories. In order to build a computational model of human intelligence, it is clear that we must understand how to process plot units. This thesis takes a step in that direction. It presents an English template for describing plot units and a system that is capable of turning these descriptions into plot-unit searches on stories. It currently processes 26 plot units, and finds 10 plot units spread out over Macbeth, Hamlet, the E-R Cyber Conflict, and a collection of legal case briefs.
