INTRODUCTION L’évaluation de la surface corporelle brûlée, essentielle pour établir la réanimation volémique et statuer sur le pronostic, se base actuellement sur la transposition des brûlures observées sur des diagrammes en papier représentant des mannequins standard. Le but de ce projet est de contribuer à la validation d’un outil pour l’évaluation des ratios brûlés. Deux outils ont été proposés, un numériseur portable et les mesures anthropométriques. MÉTHODES Quatre mannequins commerciaux avec différentes morphologies ont été sélectionnés. Chaque mannequin a été numérisé 10 fois avec un numériseur portable et une fois avec un numériseur de référence. Les surfaces corporelles totales ont été calculées et comparées. Dans un deuxième temps, 14 volontaires ont estimé la surface coporelle brûlée en utilisant les diagrammes papier et en dessinant sur un logiciel. RÉSULTATS Les valeurs des surfaces corporelles totales obtenues avec le numériseur portable sont 0,812; 1,581; 1,711 et 1,916 m2 pour les mannequins enfant, femme I, femme II et homme. Les résultats du numériseur de référence sont 0,815; 1,588; 1,716 et 1,918 m2. Les ratios des surfaces brûlées des mannequins correspondent à 23,33; 22,67, 32,63 et 26,07 % pour les mannequins. Les estimations des surfaces brûlées obtenues avec les diagrammes en papier représentent 29,9; 32,5; 40,4 et 35,7 %. Les résultats obtenus avec le logiciel sont 23,5; 22,6; 32,1 et 25,1 %. CONCLUSION Le numériseur portable reproduit avec précision et exactitude la surface corporelle totale. L’utilisation des données anthropométriques pour le calcul du pourcentage brûlé représente un outil plus précis et exact que les diagrammes papier. / PURPOSE Total body surface area burned assessment is currently based on the transpositon of burns seen on paper charts representing standard models. The purpose of this project is to contribute to the validation of a tool for TBSA assessment. A handheld 3D scanner and anthropometrical measurements have been proposed. METHODS Four commercial mannequins with different body shapes were selected. Each model was scanned 10 times with a handhed, white light scanner and once with a gold standard scanner. The images were transferred to a modelling software allowing to assess the total body surface. Total body surfaces were calculated and compared. Secondly, 14 volunteers estimated the total burned surface using paper charts and drawing on 3D virtual models. RESULTS Values of the total body surface obtained with the handheld scanner are 0.812; 1.581; 1.711 and 1.916 m2 for the child, female I, female II and male mannequins. The results of the gold standard scanner are 0.815 ; 1.588 ; 1.716 and 1.918 m2. Burn extent ratios correspond to 23.33 ; 22.67 ; 32.63 and 26.07 % for the same mannequins. Estimated burned surfaces obtained with paper diagrams are the following : 29.9 ; 32.5 ; 40.4 and 35.7 %. Results obtained with the software are 23.5 ; 22.6 ; 32.1 and 25.1 %. CONCLUSION The handheld scanner is a precise and accurate tool for the assessment of the total surface. Use of anthropometric data for the calculation of the body burned surface is a more accurate tool and less variable than the conventional paper charts.

Automated, large-scale 3D-scanning systems are important tools in culture and heritage preservation that allows museums and art institutes to digitize their collections of movable artifacts for the purpose of preservation, research, and exhibition. Unfortunately, the cost of these systems limits their usage to a handful of wealthy museums and art institutes. This thesis explores if it possible to significantly reduce the cost of such a system by presenting a viable automated, large-scale, 3D-scanning system for movable artifacts tailored to the needs of museums and art institutes. To achieve the thesis goal a market analysis was conducted to identify the need and requirements museums and art institutes have for these kinds of systems. The market analysis also explored available systems on the market and how museums and art institutes use them. The result of the market analysis identified a specific type of automated, large-scale, 3D-scanning system design suitable for market specialization. Based on the market analysis requirements for such a system design were specified and developed into a mechanical design and hardware architecture. These were then used to construct and evaluate a limited prototype as a way of validating the mechanical design and hardware architecture. The remainder of the work consisted of a cost analysis which used the hardware architecture and mechanical designs to estimate the material and component cost to produce a single unit of the developed system. The results of this thesis show that it is probable that market specialization significantly reduces the cost for museums and art institutes to purchase an automated, large-scale, 3D-scanning system compared with available market alternatives. / Automatiserade 3D-scanners som kan 3D-scanna stora volymer av konstprodukter är viktiga verktyg inom kulturhistorisk bevaring då det tillåter museum att digitalisera samlingar i syfte att bevara, forska och ställa ut. Tyvärr så är dessa system dyra och bara ett fåtal museer har resurser nog för att köpa in dem. Denna uppsats utforskar ifall det är möjligt att betydligt reducera kostnaden av ett sådant system genom att presentera en fungerande automatiserad 3D-scanner som är specifikt anpassad för museum. Arbetet började med en marknadsanalys som identifierade kraven som museum ställer på denna typ av system samt en analys av tillgängliga system på marknaden och hur museum använder dessa. Resultatet av detta arbete var att en specifik typ av automatiserad 3D-scannar lämplig för anpassning identifierades. Utifrån kraven som identifierades genom marknadsanalysen så utvecklades sedan en mekanisk och elektrisk design för systemet. Dessa användes sedan för att bygga och utvärdera en begränsad prototyp i syfte att validera den mekaniska och elektriska designen. Resterande arbete bestod av en kostnadsanalys som använde den mekaniska och elektriska designen för att utvärdera material och komponentkostnaden för att bygga en enhet av det utvecklade systemet. Slutsatsen av arbetet i denna uppsats är att det är troligt att det blir billigare för museum att köpa denna typ av system ifall de utvecklas utifrån deras specifika behov jämfört med tillgängliga system på marknaden.

This thesis discusses the optical diagnostics of electrical motor parts using a 3D scanner. It describes the construction of electrical induction motors, their heat losses, cooling and refrigeration systems that may be used by such motors. It approaches the possibilities of heat recording and briefly explains the 3D scanner’s principal. It also introduces the simulation program ANSYS which uses the finite element method. This thesis shows the post processing of the digitalized object and the simulations and compares the simulation and measurement results. The final part is devoted to the analysis of the obtained results.

This dissertation thesis is focused on the search for the presence of DIY (Do It Yourself) technologies in the practice of digital sculpting, from the beginnings of this progressive way of creation to the present. The work, through three thematic areas, answers the main research questions: What kind of technology is or has the DIY phenomenon been represented in digital sculpture? How have these technologies influenced and are influencing the development and direction of digital sculpture? Within the first thematic area, the presence of the DIY phenomenon in the beginnings of digital creation of a spatial work of art is mapped until the moment of constituting the concept of Digital Sculpture, as a designation of this new way of creation. The second area deals with specific technologies of digital sculpture, in terms of technical tools and their DIY alternatives. The development of these alternative technologies and their influence on the gradual democratization of digital sculpture tools is investigated. The third area examines the creative methods of DIY, which have been integrated into the practice of digital sculpture.
