Design and characterization of a small-scale solar sail deployed by NiTi Shape Memory actuators
No full textAbstractSolar sails exploit the radiation pressure as propulsion system for the exploration of the solar system. Sunlight is used to propel space vehicles by reflecting solar photons from a large and light-weight material, so that no propellant is required for primary propulsion. Kapton seems to be the most suitable material for the sail production and in the space missions till now activated booms as deployment systems have always been used. In this work a self deploying system based on NiTi Shape Memory wires has been designed and manufactured in a small-scale prototype. As kapton has always been employed with a thin Al coating on one or both surfaces of the sail, for the first experiments commercial pure Al thin sheets have been used in order to simulate the sail. In the small-scale prototype manufactured, three different configurations have been studied for bending the sail while two different Nitinol wires have been used as active materials for the self-deployment of the sail. Infrared lamps have been employed in order to warm the solar sail and obtain the activation of the shape memory active elements
Weldability of austenitic stainless steel by metal arc welding with different shielding gas
No full textAbstractDuring fusion welding the molten metal is shielded from contact with the atmospheric gas by means of a gaseous flux. The shielding gas prevents weld embrittlement, affects welding quality, because of its influence on filler metal transfer, and has a direct impact on welding costs as well. Argon is the most common shielding gas, often used with some adds of other gases that can be inert, as helium, or active, as CO2, O2 or H2. In this work the effects of mixtures with different composition have been considered for the arc welding of austenitic steels. Metallographic samples of welded sections have been undergone to visual and optical microscopy observations, microhardness, indentations and tensile tests
Optimization of the process parameters for the manufacturing of open-cells iron foams with high energy absorption
No full textAbstractIn this work the main results of the experimental research aimed to manufacture iron foams are reported. Iron powders (base metal) have been mixed with urea (filler agent) in different relative amounts (60% Fe- 40% urea, 50-50, 40-60 and 30-70) and then compressed in a cylindrical die in order to obtain a compact precursor. After compaction, the filler agent has been removed from each precursor in boiling water. The successive manufacturing step has been sintering and for this operation the optimum temperature has been found at 950 °C. Finally such foams have been subjected to compressive tests. Different amounts of Fe and urea match with different density and mechanical behavior in compressive tests. Energy absorbed during deformation has been calculated from the stress-strain compressive curve. Plateau stress, total strain and absorbed energy during deformation have been found strictly dependent from the iron/urea ratios

Voorraadbeheersing binnen de Koudbandwalserij van Tata Steel in IJmuiden
No full textTata Steel Group is een van de grootste staalproducenten ter wereld met vestigingen in meer dan 50 landen. Als onderdeel van de Tata Steel Group wordt in IJmuiden jaarlijks meer dan 7 miljoen ton hoogwaardig staal in de vorm van rollen bandstaal geproduceerd. Dit staal is voornamelijk bestemd voor de automobielindustrie, de bouw en de verpakkingsindustrie. Bij Tata Steel in IJmuiden wordt staal geproduceerd vanuit de basisgrondstoffen ijzererts en steenkool. Het productieproces binnen Tata Steel IJmuiden is opgedeeld in de afdeling Manufacturing Iron & Steel en Manufacturing Rolling & Coating. Binnen de afdeling Manufacturing Iron & Steel wordt ijzererts en steenkool omgezet tot vloeibaar staal. Van dit vloeibare staal wordt binnen de afdeling Manufacturing Rolling & Coating bandstaal gemaakt. De Gietwalsinstallatie, de Warmbandwalserij, de Koudbandwalserij en Coated Products zijn werkeenheden die onderdeel zijn van de afdeling Manufacturing Rolling & Coating. De Gietwalsinstallatie en de Warmbandwalserij produceren warmgewalst bandstaal. In de Koudbandwalserij wordt het warmgewalste bandstaal verder uitgewalst. Afhankelijk van de toepassing kan bij Coated Products een beschermende laag zink of verf worden aangebracht. Het productieproces in de Koudbandwalserij bestaat uit een aantal processtappen. Om er voor te zorgen dat de processen in gewenste mate onafhankelijk van elkaar kunnen produceren zijn tussen deze processtappen tussenvoorraden met halffabricaat aanwezig. In de periode voorafgaande aan dit onderzoek zijn problemen met de tussenvoorraden binnen de Koudbandwalserij gesignaleerd. Door het vol raken van tussenvoorraden dreigden installaties binnen de Koudbandwalserij en Coated Products stil te vallen. Uiteindelijk is Beitsbaan 21, een van de hoofdinstallaties van de Koudbandwalserij, in 2013 meerder malen stil gevallen als gevolg van een volle tussenvoorraad. De totale gemiste winst als gevolg van deze stilstand wordt geschat op 250 duizend euro. Om deze stilstanden in het vervolg te voorkomen is de doelstelling voor dit onderzoek als volgt geformuleerd: “Analyseer de oorzaak van de volle tussenvoorraden binnen de Koudbandwalserij en Coated Products en ontwerp een oplossing om de stilstanden van de hoofdinstallaties als gevolg hiervan te voorkomen.”Mechanical, Maritime and Materials EngineeringMarine and Transport TechnologyTransport Engineering and Logistics2014.TEL.784

Structural basis for TatA oligomerization: an NMR study of Escherichia coli TatA dimeric structure.
No full textMany proteins are transported across lipid membranes by protein translocation systems in living cells. The twin-arginine transport (Tat) system identified in bacteria and plant chloroplasts is a unique system that transports proteins across membranes in their fully-folded states. Up to date, the detailed molecular mechanism of this process remains largely unclear. The Escherichia coli Tat system consists of three essential transmembrane proteins: TatA, TatB and TatC. Among them, TatB and TatC form a tight complex and function in substrate recognition. The major component TatA contains a single transmembrane helix followed by an amphipathic helix, and is suggested to form the translocation pore via self-oligomerization. Since the TatA oligomer has to accommodate substrate proteins of various sizes and shapes, the process of its assembly stands essential for understanding the translocation mechanism. A structure model of TatA oligomer was recently proposed based on NMR and EPR observations, revealing contacts between the transmembrane helices from adjacent subunits. Herein we report the construction and stabilization of a dimeric TatA, as well as the structure determination by solution NMR spectroscopy. In addition to more extensive inter-subunit contacts between the transmembrane helices, we were also able to observe interactions between neighbouring amphipathic helices. The side-by-side packing of the amphipathic helices extends the solvent-exposed hydrophilic surface of the protein, which might be favourable for interactions with substrate proteins. The dimeric TatA structure offers more detailed information of TatA oligomeric interface and provides new insights on Tat translocation mechanism
Developing a project architecture and evaluating the Enterprise Architecture initiative at Tata Steel
No full textOrganizations have become more aware of Enterprise Architecture and the need to work under architecture. Tata Steel assumes that Enterprise Architecture can help them realizing the benefits that come from working with Enterprise Architecture as presented in literature. This thesis consists out of two parts. The first part is about the process of developing a business and application architecture, and the development of the architecture itself. An ‘as-is’ project architecture, which represents the system landscape and business processes at the start of the project, and a ‘to-be’ project architecture, which represents how the system landscape and business processes should look when the project finishes, was developed. The goal of the project for which the architecture was developed is to change the system landscape in such a way that it can support the newly developed distribution model. The second part of the thesis focuses on research questions about Enterprise Architecture. The most important goal of this thesis is to describe how Enterprise Architecture can be implemented in an organization like Tata Steel. The Enterprise Architecture approach that Tata has chosen is described, evaluated and improvements are suggested. The governance of architectural models is discussed and the value of architecture is discussed. All while using the experience gotten from creating the ‘as-is’ and ‘to-be’ project architectures.Computer Science Information ArchitectureWeb Information Systems GroupElectrical Engineering, Mathematics and Computer Scienc
