This diploma thesis .deals with a crankshaft analysis of the VW 6,0 W12 engine. The first goal is to create a CAD model from the real part, then to create a FEM model for computer simulations. With respect to a dynamic character of the loading, the crankshaft is then reduced into a MNF file for the purpose of dynamic simulations in the MBS ADAMS/Engine. The full range of working RPMs is simulated in it. Beside the crankshaft the main and pin bearings are studied too. At the last part of this thesis the durability of the crankshaft is solved.

Olika kontorstrender kommer och går och den flexibla arbetsplatsen har blivit allt vanligare i samhället. Idén om att varje individ själv ska ha möjlighet att välja sin arbetsplats efter olika arbetsuppgifter är grundtanken i det aktivitetsbaserade arbetssättet, en kontrast till de klassiska cellkontoren. Konceptet aktivitetsbaserade flexkontor bygger på att arbetsmiljön utformas i olika zoner efter verksamhetens olika aktiviteter, men tidigare forskning visar på att kontorsformen inte alltid används som den är tänkt eller att arbetsmiljön inte stödjer de behov som finns hos medarbetarna. Den här studien handlar om att undersöka de lugna zonerna i ett aktivitetsbaserat flexkontor. Studien är i samarbete med Försäkringskassans huvudkontor i Stockholm som sedan 2016 arbetat aktivitetsbaserat, men där de anställda idag ofta väljer att sitta på samma plats varje dag. Det har resulterarat i att lugna zonerna idag inte används i någon större utsträckning. Syftet med studien är att undersöka vilka rumsliga behov som användare av ett aktivitetsbaserat flexkontor har i en lugn zon och hur en lugn zon kan kommunicerar dess användande och funktioner.  Intervjuer, frågeformulär och rumsanalys har tillämpats för att få en djupare förståelse om problematiken och för att besvara frågeställningarna för denna studie. Tillsammans litteraturstudier om visuell retorik, visuella element i rummet, zonindelning samt deltagande och inkluderande design så presenteras ett gestaltningsförslag på hur ett rums funktioner kan kommuniceras genom visuella element som form, färg och material och en utformning av en lugn zon som stödjer användares behov.

Avec la croissance exponentielle du trafic lié au développement de la vidéo et des services d’Internet, les systèmes WDM évoluent régulièrement pour augmenter la capacité de la fibre optique. Pour atteindre cet objectif, les concepts d’«élasticité» et de grille WDM flexible ont été introduits et ont conduit au développement de nouveaux équipements optiques. Dans le cadre des réseaux flexibles, le dimensionnement de réseaux se complexifie, et les outils de dimensionnement traditionnels doivent être repensés. De plus, des problèmes stratégiques et technologiques apparaissent avec l’arrivée de ce nouveau concept. Presque tous les équipements optiques doivent être remplacés par d’autres mieux adaptés, entraînant un coût de déploiement additionnel. Ce travail propose et implémente des nouveaux outils mathématiques et logiciels de dimensionnement multicouche des réseaux optiques flexibles. Des cas d’usage intéressants à étudier dans le cadre des réseaux flexibles sont aussi identifiés et proposés dans cette thèse. De même, ce travail traite les problèmes principaux émanant de la flexibilité optique. De façon plus spécifique, nous étudions le problème de la fragmentation du spectre WDM flexible dans les réseaux d’opérateurs et proposons des solutions. De plus, nous proposons et évaluons un cas d’usage qui combine l’élasticité et la restauration optique du trafic dans un contexte multicouche. Enfin, nous identifions et proposons une solution au problème lié à l’utilisation des amplificateurs optiques dans les réseaux flexibles / With the exponential growth of traffic driven by video and Internet services, WDM systems evolve regularly to increase optical fiber capacity. To meet the relentless need for capacity, advanced features have been integrated into optical layer leading to the notion of channel flexibility (datarate elasticity, flex-grid). In contrast, with the potential benefits that optical channel flexibility provides, network dimensioning gets even more complicated, and traditional dimensioning tools should be rethought. Moreover, some strategic and technological problems appear with optical layer flexibility. Almost, all legacy equipment in the optical layer needs to be replaced by greenfield and well-adapted equipment, which requires new investments. Furthermore, spectrum fragmentation has been identified as the main disadvantage of optical layer flexibility. This work proposes and implements different mathematical multilayer tools for network dimensioning with the aim of evaluating optical layer flexibility. It identifies profitable and advantageous use cases and networking scenarios that bring forward the interest of flex-grid and elasticity. This work also deals with the potential troubles of flexibility and provides solutions to them. Specifically, we thoroughly investigate spectrum fragmentation in operator network context, and propose some traffic engineering strategies. We propose and evaluate a new use case that combines datarate elasticity and optical restoration within a multilayer context. Finally, we state a new drawback of flex-grid technology regarding the use of legacy optical amplifiers with flex-grid networks and provide a solution to overcome this problem

Industrial robotic arms have transformed the manufacturing environment by providing efficient and precise automation solutions. These sophisticated machines, powered by innovative technology, are capable of performing difficult tasks with speed and accuracy. The project described here is related to industrial robotics because it focuses on the creation of a gesture-controlled robotic arm. This project aims to build a robotic arm that can be controlled by gestures utilising MPU6050 sensors and flex sensors. By interpreting gestures acquired by strategically placed sensors, the robotic arm is designed to emulate human arm movements. The MPU6050 sensors are placed on the hand, near the elbow, and near the shoulder, allowing the system to capture the arm’s orientation and movement in real time. The gripper mechanism of the robotic arm is controlled by a flex sensor on the index finger. The central control unit is the Arduino UNO Rev3 SMD microcontroller, which is in charge of analyzing sensor input and translating it into matching robotic arm movements. The suggested system intends to provide a user-friendly and intuitive method for robotic arm control, with possible applications in a variety of domains such as industrial automation, medical support, and prosthetics.

I samband med olika nationella rekommendationer under Covid-19-pandemin har utvecklingen av distansarbete ökat. Den här studien har undersökt huruvida upplevd stress och allmän hälsa skiljer sig åt mellan arbetstagare med olika grad av flexibelt arbete. Inverkan av arbetsmiljöfaktorer som krav och socialt stöd har också undersökts. En blandning av att arbeta på distans och på arbetsplatsen, definieras i denna studie som flexibelt arbete. Insamling av data genomfördes med en kvantitativ metod där data samlades in via enkät. 152 respondenter i åldrarna 20–67, varav 104 kvinnor och 48 män valde att delta i studien. Den insamlade datan analyserades i SPSS med hjälp av variansanalys ANOVA, post-hoc-analys och korrelationsanalyser. Resultatet visade ingen statistisk signifikant skillnad beträffande allmän hälsa och grad av flexibelt arbete, mellan grupperna med olika grad av flexibelt arbete. Däremot framkom tendenser att de som arbetar en till två dagar i veckan på distans upplever bättre allmän hälsa jämfört med övriga grupper. Vidare visade resultatet en statistiskt signifikant gruppskillnad, de som arbetar en till två dagar i veckan på distans upplever högre socialt stöd från chef jämfört med de som arbetar tre till fem dagar i veckan på distans. Slutsatserna visar att arbetstagare som arbetar i snitt en till två dagar upplever högst socialt stöd. / The occurrence of teleworking has increased, not least in connection with various national recommendations during the Covid-19 pandemic. This study has examined whether perceived stress and general health differ between workers who work in varying degrees of telework. The impact of work environment factors, such as demands and social support has also been investigated. A combination of working remotely and in the workplace is defined by this study as flexible work. The data collection was performed using a quantitative method, a survey was used to collect data. The sample consisted of 152 respondents, aged 20-67, 104 women and 48 men. The collected data were analyzed in SPSS using variance analysis ANOVA, post-hoc analysis and correlation analysis. The results showed no statistically significant difference in general health and degree of telework when comparing the different sample groups, however, there were tendencies that those who telework one to two days a week, experience better general health. Furthermore, the results showed a statistically significant group difference, those who telework one to two days a week, experience higher social support from managers, compared with those who telework three to five days a week. The conclusion can be drawn that workers who telework at an average of one to two days a week, appear to have the highest social support.

This happens because the flexibility of the substrate can provide previously impracticable applications, due to the rigidity of the substrates normally used that makes it difficult to fit into the circuits in irregular surfaces. The constant interest in recent years for more lighter devices, increasingly more compacts, flexible and with low cost, led to a new line of research of great interest from both academic and technological views, that is the study and development of textile substrates that can be applied in the development of planar circuits, for applications in the areas of security, biomedical and telecommunications. This paper proposes the development of planar circuits, such as antennas , frequency selective surfaces (FSS) and planar filters, using textile (cotton ticking, jeans and brim santista) as the dielectric substrate and the Pure Copper Polyester Taffeta Fabric, a textile of pure copper, highly conductive, lightweight and flexible, commercially sold as a conductive material. The electrical characteristics of textiles (electric permittivity and loss tangent) were characterized using the transmission line method (rectangular waveguide) and compared with those found in the literature. The structures were analyzed using commercial software Ansoft Designer and Ansoft HFSS, both from the company Ansys and for comparison we used the Iterative Method of Waves (WCIP). For the purpose of validation were built and measured several prototypes of antennas, planar filters and FSS, being possible to confirm an excellent agreement between simulated and measured results / A utiliza??o de materiais flex?veis para o desenvolvimento de circuitos planares ? uma das caracter?sticas mais desejadas e estudadas, ultimamente, pelos pesquisadores, pois essa maleabilidade do substrato proporciona aplica??es antes imposs?veis, devido ? rigidez dos substratos normalmente utilizados o que dificultava a adequa??o dos circuitos em superf?cies irregulares. O constante interesse nos ?ltimos anos por dispositivos mais leves, cada vez mais compactos, flex?veis e com custo reduzido, levou a uma nova linha de pesquisa de grande interesse tanto do ponto de vista acad?mico quanto tecnol?gico que ? o estudo e desenvolvimento de substratos t?xteis que possam ser aplicados no desenvolvimento de circuitos planares, para aplica??es nas ?reas de seguran?a, biom?dica e telecomunica??es. Este trabalho prop?e o desenvolvimento de circuitos planares, tais como antenas, superf?cies seletivas de frequ?ncia (FSS) e filtros planares, utilizando tecidos (lona, jeans e brim santista) como substrato diel?trico e o tecido Pure Copper Polyester Taffeta Fabric, um tecido de cobre puro, altamente condutivo, leve e flex?vel, comercialmente vendido como material condutivo. As caracter?sticas el?tricas dos tecidos (permissividade el?trica e tangente de perda) foram determinadas utilizando o m?todo de linha de transmiss?o e comparadas com os encontrados na literatura. As estruturas foram analisadas utilizando os softwares comerciais Ansoft Designer, Ansoft HFSS ambos da empresa Ansys e para efeito de compara??o foi utilizado o M?todo Iterativo das Ondas (WCIP). Para efeito de valida??o foram constru?dos e medidos v?rios prot?tipos de antenas, FSS e filtros planares sendo poss?vel constatar uma excelente concord?ncia entre os resultados simulados e medidos
