Esta dissertação introduz o conceito de cortes KL, o que permite controlar tanto o número K de entradas como o número L de saídas em uma região de um circuito. O projeto de um circuito digital pode ser dividido em duas fases: síntese lógica e síntese física. Dentro de síntese lógica, um dos principais passos é o mapeamento tecnológico. Tradicionalmente, o processo de mapeamento tecnológico somente lida com funções de saída única, para a construção de circuitos. O objetivo deste método é explorar o uso de blocos de múltiplas saídas no mapeamento tecnológico. Para prover escalabilidade, o conceito de fatoração de cortes é estendido para os cortes KL. Algoritmos para enumerar esses cortes e também para enumerar alguns subconjuntos de cortes com características específicas são apresentados e os resultados são mostrados. Como exemplos de aplicações práticas, diferentes algoritmos de cobertura são propostos. O algoritmo guloso é uma alternativa simples e produz bons resultados em área, mas é muito restritivo, pois não é factível em mapeamento orientado à atraso. Outro algoritmo de cobertura apresentado é uma extensão do algoritmo de fluxo de área e permite a utilização de cortes com várias saídas, mantendo possível a consideração de outros custos. Um algoritmo de correspondência Booleana que é capaz de lidar com blocos com múltiplas saídas também é descrito. Isso permite a utilização de uma biblioteca padrão com células com mais de uma saída no mapeamento tecnológico. Os resultados mostram a viabilidade e utilidade do método. / This thesis introduces the concept of KL-feasible cuts, which allows controlling both the number K of inputs and the number L of outputs in a circuit region. The design of a digital circuit can roughly be divided in two phases: logic synthesis and physical synthesis. Within logic synthesis, one of the main steps is the technology mapping. Traditionally, the technology mapping process only handles single output functions, in order to construct circuits. The objective of this method is to explore the use of multiple output blocks on technology mapping. To provide scalability, the concept of factor cuts is extended to KL-cuts. Algorithms for enumerating these cuts and also for enumerating some subsets of cuts with some special characteristics are presented and results are shown. As examples of practical applications, different covering algorithms are proposed. The greedy algorithm is a simple alternative and produces good results in area, but it is too restrictive, as it is not practical in timing oriented mapping. The other covering algorithm presented is an extension to the area flow algorithm and allows cuts with multiple outputs to be used while making possible the control of some other costs. A Boolean matching algorithm that is able to handle multiple output blocks is also described, which permits the use of a standard cell library with more than one output on technology mapping. The results show the viability and usefulness of the method.

Fuktskador är ett problem som kan uppstå vid byggnation i trä om konstruktionen exponeras för nederbörd under byggtiden. Mätning av fuktkvoter i trä kan utföras med flera olika instrument och metoder. Syftet med arbetet är att studera fuktkvotsförändringar i korslimmade träelement som utsätts för långvarig nederbörd i laborationsmiljö. För att utveckla detta område har Linnéuniversitetet tillsammans med Saab utvecklat ett eget mätinstrument. Instrumentet mäter resistans i trä som jämförs med mätvärden från ett annat instrument vid namn Gigamodule. Det egenutvecklade sensorkortet är fortfarande under utveckling. Förutom i arbetets försöksuppställning testas instrumentet även i en byggnad i Växjö. För kontroll av mätresultat har fler metoder och instrument använts. Två modeller har använts som representerar detalj vid anslutning av väggelement-och mellanbjälklag. Båda modellerna har under lika lång tid varit nedsänkta i vattenbad. Försöksuppställningen har utförts mellan 19:e april och 18:e maj 2018. Mätningar och beräkningar har resulterat i jämförbara resultat. Skillnader i resultat utifrån träets fiberriktning har visats från flera instrument. KL-träelementen har uppvisat en god förmåga att trots höga fuktkvotsvärden torka ut och återgå mot normala värden under mätperioden. / Moisture related damage is an occurring problem in wood-based buildings if the material is exposed to rainfall during construction. Measurement of moisture content can be done with various instruments and methods. The purpose of the thesis is to study change in moisture content in cross-laminated-timber, with prolonged exposure to water in laboratory environment. To advance the field, the Linnaeus University has been developing a measurement instrument of their own in collaboration with the company Saab. The instrument measures electrical resistance in wood where the obtained values will be compared to similar measurements from a product named Gigamodule. The self-developed sensor card is still a product under development. In addition to the lab setting measurements the instrument was also installed in a local building in Växjö. To verify the result from the previously mentioned resistance measurers additional instruments and methods have been utilized. Two separate models have been used to represent the detail of the connection between the wall element and the joist. Both models have been submerged under water for an equal amount of time. The experimental setting took place between the 19th of April to the 18th of May 2018. The measurements and calculations have been resulting in values that can be the subject of internal evaluation. Difference in result based on the direction of the grain have been observed in several measurement methods. The CLT-elements demonstrated good drying properties despite periodically high moisture content and the wood indicate a return towards initial levels of moisture.

The construction of wooden multi-storey buildings creates issues with the acoustic environment. To meet Boverkets soundproofing requirements the solutions of today results in thick partition building components taking up potential floor space. Crosslaminatedtimber is a solid timber slab that can be manufactured in varying sizes and thicknesses. These boards can then be used as supporting elements in walls, ceilings and floors. This study investigates whether cross-laminated timber can be used to streamline the construction of multi-storey wooden buildings. In this comparative survey a reference building constructed by A-hus was used and current loads, sound insulation, use of floorspace and economy were analyzed. Four different alternative walls and one floor constructed with cross-laminated timber have been studied according to the above named criteria, and then compared with the reference building. The result indicates that a wall with 80 mm cross-laminated timber board has the load capacity required, improves sound insulation and saving 16 m2 of floorspace in the reference building valued to approximately 695,000 SEK in increased sales revenue. Using cross-laminated timber in the floor does not sufficient improve A-hus current construction system and should therefore not be interesting.

Syfte: Stål och betong har länge varit dominerande inom byggnation av den anledningen att flervåningshus med en stomme i trä mellan 1874 och 1994 i Sverige inte varit tillåtet. Detta har lett till att erfarenhet och kunskap inom flervåningshus i trä inte har utvecklats i samma takt. Med en ökad medvetenhet om miljön är nu fler intresserade av att bygga i trä då materialet anses vara bättre ur en miljösynpunkt. KL-trä har möjligheten att konkurrera med stål- och betongelement i bärighet och hållfasthet men står inför andra utmaningar när det kommer till brand- och ljudkrav. Målet med studien är att ta fram underlag för arbetsmoment, arbetstid och exempel på tvärsnittslösningar som använts för att upprätta mer korrekta kalkyler och tidplaner i anbudsskedet vid val av en KL-trästomme eller betongstomme i bostäder. Metod: Undersökningen genomförs som en kvalitativ fallstudie där analys sker av både kvantifierbara sekundärdata i form av enhetstider och tidigare tvärsnittslösningar, så väl som kvalitativ primärdata från semistrukturerade intervjuer. Genom triangulering av insamlade data tas tvärsnitt fram som utgör jämförelsen mellan KL-trä och prefabricerad betong med hänsyn till arbetsmoment och arbetstid.  Resultat: KL-trästommen kräver med hänsyn till brand- och ljudkrav fler arbetsmoment och en längre enhetstid än vad en prefabricerad betongstomme gör. Resultatet baseras på en kvadratmeter av tvärsnitten. Arbetsgången mellan de olika stommaterialen skiljer dessutom där betong efter sitt stommontage anses mer färdigt medan en KL-trästomme kräver fler påbyggda skikt. Konsekvenser: Studien grundas på en kvadratmeter i ett tvärsnitt i stället för en bredare bild av ett helt projekt. Vidare rekommenderas att kommande studier behandlar fler stomdelar, fuktsäkerhet och övergripande tidsåtgång för arbete med de olika stommaterialen. Begränsningar: Studien tar endast hänsyn till bjälklag och lägenhetsskiljande väggar i KL-trä respektive prefabricerad betong. Sekundärdata i form av tvärsnitt är endast insamlat från en av vardera källor rörande stommaterialen, nämligen organisationerna Svenskt Trä och Svensk Betong. Enhetstiderna är tagna ur Ny- och ombyggnadslistan 2018 men är kompletterade med respondenters ackordsunderlag. Intervjuerna är utförda med respondenter från byggbranschen som varit involverade i ett eller flera projekt med antingen KL-trästomme eller prefabricerad betongstomme. / Purpose: Steel and concrete has for a long time been dominating in construction because of the reason that multi-storey buildings of wood were forbidden between 1874 and 1994 in Sweden. This has led to that experience and knowledge about multi-storey buildings made of wood have not developed in the same rate. With an increase of awareness about the environment, more have now become interested of building with wood since it is deemed better for the environment. Cross-laminated timber (CLT) can compete with steel and concrete elements in terms of load-bearing capacity and strength of material but face other challenges when it comes to fire and sound regulations. The goal of this study is to bring forward information about work activities, working hours and example of used cross-section solutions to execute more correct calculations and time schedules for projecting with either CLT or concrete in housing.  Method: The study will be conducted as a qualitative fall study were analysis of both quantifiable secondary data in shape of unit times and earlier used cross-section solutions as well as qualitative primary data from semi-constructed interviews. Through triangulation of the collected data a cross-section will be selected that will compose the comparison between CLT and precast concrete regarding work activities and working hours. Findings: CLT frame requires more work activities and a longer working time than a prefabricated concrete frame with regards to fire and sound regulations. The result is based on a square meter of the cross-section. The work process differs between the different materials were a concrete frame, after it has been assembled is deemed more complete than a CLT frame which requires more layers for completion. Implications: The foundation of the study was formed on a square meter of a cross-section instead of a wider picture of a complete project. Further recommendations for upcoming studies are to include more frame parts, moisture safety and a general timescale of working with the different materials. Limitations: The study includes apartment differencing floors and walls of CLT and prefabricated concrete. Secondary data are only collected from one of each material, these are collected from the organizations Swedish Wood and Swedish Concrete. Unit times are taken from the New- and Reconstruction list 2018 (Ny- och ombyggnadslistan 2018) and these are complemented with response from the interviews. The interviews are conducted with respondents from the construction industry who has been involved in one or more projects with either a CLT frame or a precast concrete frame.

Purpose: The purpose of this study was to investigate whether timber-concrete composite (TCC) floors made of a CLT-deck and casted concrete could be used as a method for increasing the use of wood as a building material. Method: The methods used in this degree project were a literature study, in which a number of laws of construction and different connector systems were studied, as well as an experiment consisting of bending tests on CLT-decks with casted concrete where SFS VB-screws were used as shear connectors. Results: The TCC-beams in the experiment behaved as expected and went to bending failure. The beams displayed an almost invisible slip between the materials despite the low composite action of 40,2 %. In addition, the beams had a higher bending stiffness on average than CLT-beams of the same height would have. Conclusions: Compared to floors made entirely of wood, TCC-floors with CLT add extra mass, stiffness, and better acoustic properties to the construction while maintaining a low floor height. The three main types of connectors used in TCC floors are mechanical, notched and glued-in connectors, where the latter two generates higher composite action and stiffness. Adhesive connection is another method with great potential, but there is still more research needed for this type of connection to be used.
