Ambos os problemas ocorrem no corrugador, máquina multiestágio que produz as chapas de papelão ondulado. O PMTGRC surge da necessidade de minimizar trocas de gramaturas e rolos corrugadores durante o processo de produção dos boletins, uma vez que cada boletim traz as gramaturas específicas das camadas da chapa, além do tipo de onda empregada no(s) miolos(s). O sequenciamento dos boletins impacta na quantidade de mudanças de gramaturas nos porta-bobinas e se haverátrocaderoloscorrugadoresparadoisboletinssubsequentes. Astrocasdegramaturas impactam em custos de transporte de bobinas e as trocas de rolos corrugadores impactam em perda de produtividade. Para o PMTGRC propomos quatro modelos inéditos de programação inteira capazes de integrar essas duas considerações. O PABC integra várias considerações relacionadas à alocação das bobinas no corrugador, como por exemplo, a minimização das sobras não aproveitáveis e das quantidades de consumos parciais, fatores que influenciam diretamente nos custos de produção. Um modelo linear inteiro misto inédito é proposto, determinando quais bobinas serão utilizadas em cada porta-bobinas. Além disso, propomos uma estratégia de sequenciamento das bobinas em cada porta-bobina, evitando paragens no corrugador. Uma série de testes computacionais utilizando instâncias geradas com base em dados reais foram realizados. Os resultados indicam que os modelos foram eficientes em tratar os problemas propostos. / In this thesis we approached two real problems identified over the productive process of corrugated cardboard industries, which we will denote as the Minimization of Converting Weights and Corrugators Problem (MCWCP) and the Corrugators Coil Allocation Problem (CCAP). Both of these problems happen in the corrugators, a multistage machine which produces corrugated cardboard. The MCWCP appears from the necessity to minimize changes of weight and corrugator rolls during the production process of the bulletins, since each one brings the specific layers’s weight of the sheets, besides the kind of wave put in the middle. The sequence of bulletins impact in the number of weight changes in the coil holders and if there will be corrugating rollers’s exchange for two following bulletins. The gramature’s exchanges impact in the costs of transportation and the corrugating rollers exchange causes lost in the productivity. We propose four whole programming models capable of integrating both considerations. The CCAP integrates many considerations related to the coils’s allocation on the corrugators, for example, the minimization of the non-usable leftovers and the amount of partial consumption, factors which influence directly on the production’s costs. A whole new mist linear model is proposed, determined which coil on the corrugators are going to be used in each coil holder. Besides this, we propose a sequel strategy for the coils in each coil holder, avoiding stops on the corrugators. A series of computation tests using instances created based on real data were made. The results indicate that the models were efficient in solving the problems.

The project aimed at conceptually develop a solution that is able to automatically transfer an already stacked and measured heap of goods from an order tote into an erected corrugated cardboard box, whereas the dimensions of the corrugated cardboard box and the stack are allowed to vary within a specified interval. The method for this project consisted of five main parts: feasibility study; concept generation; concept choice; design; and evaluation. The project was initiated by a feasibility study where the problem was clarified and knowledge regarding the problem was gathered. The feasibility study resulted in an user requirement specification and a product requirement specification. The product requirement specification was utilized in the evaluation processof the final developed concept. The concept generation was conducted according to structured methods prescribed by Ulrich and Eppinger. The concept choice was done by the use of Pughs concept choice matrix. The result of this project consists of a conceptual proposal of how the previously described problem may be solved. The final developed concept resulted in a cad model. The evaluation showed that the concept did not fulfill the product requirement specification, despite this it is assessed that the concept in its working principle has good merits that are worth further investigation. Further development of the concept remain and validation of the working principle is needed. Further choices concerning form, material, and components remain. The report contributes to a foundation for further development of an automated filling mechanism for erected corrugated cardboard boxes.

Os efeitos da interferência antrópica podem ser monitorados através de vespas solitárias, nidificantes em cavidades preexistentes e abelhas sem ferrão. Desta forma, objetivou-se comparar a composição dessas comunidades em áreas de maior (A1) e menor (A2) interferência antrópica em um fragmento urbano de Mata Atlântica. Para investigar a composição de vespas, foram instalados e monitorados, durante um ano, ninhos armadilha de bambu e cartolina de diâmetros variados, em um transecto representante de cada uma das áreas. A fim de comparar os mesmos locais quanto às espécies de meliponíneos residentes, foram feitas buscas de ninhos, por meio de deslocamentos ao longo das trilhas existentes nas áreas arborizadas do Jardim Botânico de Juiz de Fora, MG, que representaram a área A1, e no entorno das antigas construções, representando a área A2. Em relação às vespas, três das quatro espécies coletadas são adaptadas a ambientes modificados, e por esse motivo, houve maior riqueza (n=3) e abundância (n= 21) nessa área, sendo uma espécie (Pachodynerus sp.) exclusiva dessa localidade. O gênero Trypoxylon foi o mais representativo, sendo que 74,07% dos seus ninhos pertenceram a área com maior interferência antrópica. Os gomos de bambu foram utilizados com maior frequência (64,28%) e amostraram todas as espécies de vespas desse estudo. A abundância de ninhos em cada mês esteve correlacionada positivamente com temperatura média (rs= 0,44; p= 0,007), mas só houve correlação com a precipitação, nos meses de dezembro e janeiro. A similaridade entre a composição das espécies de vespas e de abelhas nas áreas A1 e A2 foi moderada (Cs= 0,66; Cs= 0,61), respectivamente; porém, a abundância das mesmas foi semelhantes (t= 1,96/ p= 0,097). Em relação às abelhas sem ferrão, a área A1 apresentou não apenas uma maior densidade de ninhos (80%) e riqueza de espécies (n=8) que a área A2 (n=5), como também em relação a outros estudos em áreas modificadas. A alta densidade de ninhos nessa localidade foi devido a 56,66% pertencerem a Nannotrigona testaceicornis e Tetragonisca angustula, espécies muito encontradas em locais urbanizados. Já a baixa riqueza e abundância de ninhos na área A2, foi, em parte, pelo fato de essa área encontra-se em estágio de sucessão inicial. O estabelecimento dos Hymenoptera amostrados nesse estudo em área de maior interferência antrópica, só foi possível porque a oferta de recursos naturais é suficiente à sobrevivência das espécies. / Environmental changes by human action may favor some species and compromising the existence of other. The effects of the anthropogenic impact can be monitored through solitary wasps that made nests in trap nesting and stingless bees. Thus, the objective was to compare the composition of these communities in areas of greater (A1) and lesser (A2) anthropogenic interference, in an urban fragment of the Atlantic Forest. To investigate the composition wasps were installed and monitored during one year, trap nesting made of bamboo and cardboard, with varying diameters in a representative transect in both areas. In order to compare this locations as the resident species of stingless bees, were made searches for nests along existing trails in the wooded areas of the Jardim Botânico de Juiz de Fora, Minas Gerais, representing the A1 area, and surrounding the old buildings, representing the A2 area. In relation to wasps, three of the four species collected are adapted to changing environments, and therefore, a greater richness (n = 3) and abundance (n = 21) in this area, with one species exclusive of this location (Pachidynerus sp). The Trypoxylon gender was the most representative, with 74.07% of their nests belonged to area with greater human interference. The bamboo canes were frequently used (64.28%) and sampled all kinds of wasps in this study. The abundance of nests in each month was positively correlated with mean temperature (rs = 0.44; p = 0.007), but just only have correlation with rainfall in December and January. The similarity between the species composition of wasps and bees in the areas A1 and A2 was moderate (Cs = 0.66; Cs = 0.61), respectively; but plenty of them was similar (t = 1.96 / p = 0.097). Regarding the stingless bees, the area most affected by human activity, had not only a higher density of nests (80%) and richness of species (n = 8) the A2 area (n=5), but also in relation to other studies in areas modified. The high density of nests in this location was due to 56.67% belong to Nannotrigona testaceicornis and Tetragonisca angustula, species broadly found in urbanized areas. The low richness and abundance of nests in the area A2, was, in part, because this area is at an early succession stage. The establishment of Hymenoptera sampled in this study in an area of greater human interference, was only possible because the supply of natural resources is sufficient for the survival of the species.

In diploma thesis the process of enzymatic hydrolysis of waste paper as a source for the production of liquid biofuels is discused. It follows directly the homonymous diploma thesis from Ing. Brummer, and it is based on the findings, which were solved and decided in previous work. In the theoretical part there is a summarization of basic information on the enzymatic hydrolysis of waste paper and the associated influences of various factors of the rate and degree of hydrolysis. Higher attention is paid to a waste cardboard and its pretreatment methods due to the maximalization of the yield of hydrolysis. The next part summarizes options of the fermentative production of biofuels, focusing on the method of simultaneous saccharification and fermentation, where the further appropriate organism for ethanol fermentation is discussed. The last part is about the technological process from the raw material input to the separation of ethanol. In the experimental section the pre-treatment of waste paper in order to maximize the efficiency of hydrolysis was examined. The best results were achieved using a vibratory mill. In addition, various parameters for simultaneous saccharification and fermentation were optimized using enzymes from Novozymes® company and the yeast Saccharomyces cerevisiae. The conversion rate of waste paper cellulose to reducing sugars was observed by spectrophotometric method by Somogyi - Nelson and the amount of produced ethanol was quantified using HPLC / RI. As a part of this thesis some conditions (amount of enzyme, substrate, nutrients, yeasts, temperature, pH, type of buffer) were optimized to maximize the effectiveness of the overall process. All experiments were carried out on corrugated cardboard, which was chosen as the most promising material for hydrolysis that was among the waste paper pulp in diploma thesis by Ing. Brummer.

The corrugated board is considered as the second most used packaging material and the world’s environmentally acceptable solution for packaging, with wide range of applications. After the manufacturing process, the corrugated board is cut into sheets and stored in a stack until optimum moisture content has been reached in order to avoid undesired properties. However, due to complex and various structures, it is difficult to estimate the appropriate time so to achieve the acceptable moisture level of the corrugated board stack. So a homogenized model of the stack has to be created which will have the same average properties as the real stack. In order to achieve this goal the behavior of a smaller part of the stack, the unit cell, is investigated. In the second step a homogenized model is created with the average transport of mass and heat. At the end, the unit cell is scaled up. In this master thesis, only the first and the second steps were simulated. This was achieved by creating a 3-D mathematical model using finite element method and simulating its properties in COMSOL Multiphysics®. Four mathematical models were used in the description of the 3-D model: the heat transfer, the moisture transfer, the vapour concentration and the gas pressure. Moreover, by applying the gradient in one direction in each case, the behavior of the detailed unit cell was investigated. Finally different simplified geometries were created and investigated so to approach a homogenized model which described better the average properties of the detailed model. By comparing the results of the models, it was concluded that the homogenized models 2 and 3 approached the values of the second detailed model but only inside of the unit cell. However, the deviation was not negligible and further investigation is required in order to find a new homogenized method.

Kraftliners är något som används till att skapa bland annat ytskiktet till pappersprodukten wellpapp. Wellpapp består av ett lager kraftliner på antigen en- eller vardera sidan av ett vågigt papper, kallat flute. På uppdrag av SCA R&D undersöker detta kandidatarbete möjligheten till att skapa en konceptuell prototyp till en maskin som kan konstruera wellpappsprover på deras laboratorium. Detta för att via tester kunna prediktera hur variationer i wellpappens struktur påverkar dess egenskaper. Arbetet utfördes med hjälp av en iterativ metod där koncept först togs fram och sedan utvärderades repetitivt tills ett slutgiltigt koncept var framtaget. Konceptframtagningen bestod av fem iterationer med faserna konceptgenerering, modellering, prototypframtagning, tester av prototyp och utvärdering. Arbetet resulterade i ett slutgiltigt koncept som ledde till en illustrerad prototyp i mindre skala som visar hur wellpappsprover skulle kunna skapas i SCA’s R&D-laboratorium. / Kraftliners are used to create, among other things, the surface layer for the paper product corrugated board. Corrugated board consists of a layer of kraftliner on either one or both sides of a wavy paper, called flute. On behalf of SCA R&D this bachelor's thesis investigates the possibility of creating a conceptual prototype for a machine that can create corrugated board samples in their laboratory. This is to be able to predict, via tests, how variations in the structure of the corrugated board affect its properties. The work was carried out using an iterative method where concepts were first developed and then evaluated repetitively until a final concept was developed. The concept development consisted of five iterations with the phases of concept generation, modeling, prototype development, prototype testing and evaluation. The work resulted in a final concept that led to an illustrated prototype on a smaller scale that shows how corrugated board samples could be created in SCA's R&D laboratory.
