It is an object of sports equipment, which will be mainly used for ice hockey, as well as for the organization of other sporting and social events. The main objective in the design of architectural buildings were to meet modern requirements for the operation and use of the sports hall. Mass solution hall is designed as part of a hyperbolic curve, which rotates around a central axis. This substance is added next curve and along the perimeter. It is a sine wave, which is twice reflected on the mass of the object. This curve separates the roofing structure from the construction and glazing adds mass element dynamics, which is in my opinion the sporting character of the buildings needed. Construction is due to this curve seems to be constantly moving. This curve has another purpose and that the highest point of the curve are a total of two, is the main entrances to the building and the curve that creates a kind of "entry portal".

Carbon nanofibers (CNFs) used as nano-scale reinforcement have been extensively studied since they are capable of improving the physical and mechanical properties of conventional fiber reinforced polymer composites. However, the properties of CNFs are far away from being fully utilized in the composites due to processing challenges including the dispersion of CNFs and the viscosity increase of polymer matrix. To overcome these issues, a unique approach was developed by making carbon nanopaper sheet through the filtration of well-dispersed carbon nanofibers under controlled processing conditions, and integrating carbon nanopaper sheets into composite laminates using autoclave process and resin transfer molding (RTM). This research aims to fundamentally study the processing-structure-property-performance relationship of carbon nanopaper-based nanocomposites multifunctional applications: a) Vibrational damping. Carbon nanofibers with extremely high aspect ratios and low density present an ideal candidate as vibrational damping material; specifically, the large specific area and aspect ratio of carbon nanofibers promote significant interfacial friction between carbon nanofiber and polymer matrix, causing higher energy dissipation in the matrix. Polymer composites with the reinforcement of carbon nanofibers in the form of a paper sheet have shown significant vibration damping improvement with a damping ratio increase of 300% in the nanocomposites. b) Wear resistance. In response to the iv observed increase in toughness of the nanocomposites, tribological properties of the nanocomposite coated with carbon nanofiber/ceramic particles hybrid paper have been studied. Due to high strength and toughness, carbon nanofibers can act as microcrack reducer; additionally, the composites coated with such hybrid nanopaper of carbon nanofiber and ceramic particles shown an improvement of reducing coefficient of friction (COF) and wear rate. c) High electrical conductivity. A highly conductive coating material was developed and applied on the surface of the composites for the electromagnetic interference shielding and lightning strike protection. To increase the conductivity of the carbon nanofiber paper, carbon nanofibers were modified with nickel nanostrands. d) Electrical actuation of SMP composites. Compared with other methods of SMP actuation, the use of electricity to induce the shape-memory effect of SMP is desirable due to the controllability and effectiveness. The electrical conductivity of carbon fiber reinforced SMP composites can be significantly improved by incorporating CNFs and CNF paper into them. A vision-based system was designed to control the deflection angle of SMP composites to desired values. The funding support from National Science Foundation and FAA Center of Excellence for Commercial Space Transportation (FAA COE CST) is acknowledged.

This project seeks to design and construct a track-driven radio controlled vehicle and controller. The purpose is to research if radio can be effectively used to control the robot remotely, as well as research to what extent a tracked design increases the mobility when compared to a wheel-design. The prototype consists of two parts: Vehicle and controller. The vehicle is track-driven with two DC-engines connected by H-bridge. A receiver is fitted to the vehicle. The controller consists of two joysticks, a linear potentiometer as well as a transmitter. Testing was performed by driving the vehicle on different terrain.The results show that it is possible to control via RC and that the vehicle had increased mobility compared to wheeled designs. Two problems were identified: Firstly, the tracks used lacks friction, causing the vehicle to glide when attempting to climb certain objects. Secondly, due to the design of the chassis, objects contact the chassis body instead of the tracks. Causing the vehicle to stall. / Detta projekt menar att designa samt konstruera ett banddrivet radiostyrt fordon och tillhörande kontroll. Syftet med detta är att forska om radiostyrning kan effektivt användas för fjärrstyrning och för att undersöka om band-drift ökar fordonets rörlighet jämfört med hjuldrivna motsvarigheter. Prototypen består av två delar; fordon och kontroll. Fordonet är band-drivet med två DC-motorer med högt drivmoment kopplade till en H-brygga. En mottagare är monterad på fordonet. Kontrollen består av två joysticks, en linjärpotentiometer samt en sändare. Testen genomfördes genom att låta fordonet köra över olika terräng. Resultaten av testerna visade att det är möjligt att fjärrstyra med RC samt att fordonet hade ökad rörlighet jämfört med hjuldrivna motsvarigheter. Två problem identifierades under testen. Banden saknar friktion och glider ibland i stället för att klättra över hinder. På grund av chassits form kolliderade ibland objekt med chassit före banden vilket stoppade fordonet.

This knowledge has fundamental importance for the textile industry since it can quantify, in an objective way, the tactil. The fabrics used were characterized by friction and mechanical tests for determining the viscoelastic region, wear resistance and friction coefficient of the fabrics used. The stress-strain curve was obtained by the method Kawabata, KES-FB1. Wear tests performed with the aid of equipment Martindale. The measurement of friction coefficient, two methods were used and analyzed comparatively. The first was a method already established worldwide known as KES-FB4 and the second was an innovative method called FRICTORQ, developed by the University of Minho. These two methods were compared taking into account the relative motion between the tribologycal pairs are different from each method. While the first motion is translational, the second is rotational. It was formal that the knitted had a multifunctional fabrics tribologycal performance which was better than the basic knitted fabrics, as the viscoelastic region, was laager highlighting a multifunctional structure, with greater wear resistance mainly on the back side of the knitted fabrics and lower friction coefficient. Performing a comparative analysis between two methods used to measure the friction coefficient, it was formal that both methods were consistent in terms of results. In operational terms, the FRICTORQ showed ease of operation and increased reproducibility of results / O presente trabalho consiste nas an?lises das propriedades tribol?gicas de tecidos de malhas b?sicas e de malhas multifuncionais. Esse conhecimento ? de fundamental import?ncia para a ind?stria t?xtil uma vez que pode quantificar, de forma objetiva, o sentido do toque. Os tecidos utilizados foram caracterizados atrav?s de ensaios mec?nicos e de atrito, para determina??o da regi?o viscoel?stica, resist?ncia ao desgaste e coeficiente de atrito. A curva tens?o-deforma??o foi obtida pelo m?todo Kawabata, KES-FB1. Ensaios de desgaste foram realizados com aux?lio do equipamento Martindale. Para a medida do coeficiente de atrito, nos dois m?todos que foram utilizados e analisados comparativamente. O primeiro m?todo j? consolidado mundialmente, denominado KES-FB4 e o segundo m?todo inovador, denominado FRICTORQ, desenvolvido pela Universidade do Minho. Esses dois m?todos foram comparados levando-se em considera??o que os movimentos relativos entre os pares tribol?gicos s?o diferentes em cada m?todo. Enquanto no primeiro o movimento ? translacional, no segundo ? rotacional. Verificou-se que as malhas multifuncionais apresentaram um desempenho tribol?gico superior ?s malhas b?sicas, determinadas pela maior regi?o viscoel?stica, destacando a estrutura multifuncional, maior resist?ncia ao desgaste principalmente no lado avesso das malhas e menor coeficiente de atrito. Analisando comparativamente os dois m?todos utilizados para medi??o do coeficiente de atrito, verificouse que ambos foram consistentes em termos de resultados. Em termos operacionais, o FRICTORQ foi o que apresentou maior facilidade de opera??o e maior reprodutibilidade dos resultados
