fossils, production engineering, robotics, pattern recognition., General Works, Social sciences (General), and H1-99

In the case of delicate elements such as fossils, the use of the scanner is the most appropriate, the scanner uses a technology that allows the collection of information digitally with the purpose of: information gathering, modeling or restoration or even after modeling , individual element assemblies can be made to duplicate elements or recreate whole bodies. The results of the application developed in this work, have approximations very close to the real ones, evidencing the effectiveness of the developed methodology. Subsequently and once the 3D model is obtained, the necessary operations for the reproduction of the reconstructed fossil are carried out using rapid prototyping equipment; for which suitable software is used to allow these procedures to be carried out, and in this way to carry out the complete integration from 3D scanning to obtaining the final element in digital or physical form.

paper prototyping, multi-method approach, usability, evaluation, think-aloud, advanced scribbling, handicraft task, Social sciences (General), and H1-99

This article describes a multi-method approach for usability testing. The approach combines paper prototyping and think-aloud with two supplemental methods: advanced scribbling and a handicraft task. The method of advanced scribbling instructs the participants to use different colors for marking important, unnecessary and confusing elements in a paper prototype. In the handicraft task the participants have to tinker a paper prototype of their wish version. Both methods deliver additional information on the needs and expectations of the potential users and provide helpful indicators for clarifying complex or contradictory findings. The multi-method approach and its surplus benefit are illustrated by a pilot study on the redesign of the homepage of a library 2.0. The findings provide positive evidence for the applicability of the advanced scribbling and the handicraft task as well as for the surplus merit of the multi-method approach. The article closes with a discussion and outlook. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs150379

For this a literature review and interviews with professionals was held. With the results we can see the difficulty that professionals have to define the public to create the pieces. We also found that most professionals understand the importance of measures table however end up adjusting the empirically, and the realization of prototype testing many choose models that does not match the reality of the public company

prototipado rápido, diseño asistido por computadora, cirugía maxilofacial., Dentistry, RK1-715, Medicine (General), and R5-920

Advances in computer technology and the different medical images techniques such as computed tomography (CT), magnetic resonance imaging (MRI) and others, as well as its rapid introduction into social practice have created new possibilities in reconstructive surgery and replacement of tissues and organs. This article sets out very briefly the developments in the use of these techniques with some examples of their application in reconstructive surgery, in order to upgrade specialists about the potential of these technologies in this field. While the computer design allows modeling the different characteristics and properties of tissues, the data obtained by digital processing of medical images reveal, with high resolution, the shape and dimensions of different parts of the human body to repair or replace. The combined use of these technologies known as rapid prototyping technologies (RPT) has revolutionized reconstructive surgery of tissues and organs, allowing not only the manufacture of different types of custom implants but allowing action from training to planning the surgery itself. Keywords: Rapid prototyping, computer aided design, reconstructive surgery, maxillofacial surgery.

irrigação localizada, hortas agrícolas, inovações tecnológicas, microsprinkler, vegetable crops, technology innovation, Agriculture (General), and S1-972

Objetivou-se, com este trabalho, construir protótipos de microaspersores, com boa uniformidade de distribuição para irrigações com sobreposição em hortas agrícolas, utilizando-se os processos de prototipagem rápida e torneamento mecânico. O estudo foi conduzido na ESALQ/USP e no Centro de Tecnologia da Informação Renato Archer (CTI). Utilizou-se o coeficiente de uniformidade de Christiansen na avaliação do desempenho dos emissores. O PVC e o tecnyl foram os materiais que apresentaram mais facilidade na construção dos protótipos no processo de torneamento mecânico, porém o PVC foi o escolhido devido ao melhor acabamento. Os protótipos construídos com torneamento mecânico apresentaram resultados satisfatórios ressaltando tratar-se de um processo bastante artesanal e laborioso; já com a prototipagem rápida se construíram protótipos com melhores acabamentos e mais rapidez. A utilização da prototipagem rápida no desenvolvimento de equipamentos de irrigação é algo totalmente inovador e de caráter pioneiro, além de uma ferramenta de grande utilidade na área de inovação de produtos no setor de Engenharia Agrícola.The present study had the objective of developing prototypes of microsprinkler with good distribution uniformity to irrigate with overlap in vegetable crops, by rapid prototyping and mechanic tournament. The work was carried out in the Hydraulic Laboratory of the Escola Superior de Agricultura "Luiz de Queiroz", University of Sao Paulo, Brazil, and in the Centro de Tecnologia da Informação Renato Archer (CTI). Two processes were tested in the development of the microsprinkler prototypes rapid prototype and mechanical lathing. Christiansen Uniformity Coefficient was used as indicator to evaluate the distribution uniformity. Among the tested materials, the PVC and the technyl showed more facility in the prototype development in the mechanical lathing process, however, the PVC was chosen due to better finishing. The prototypes built by mechanical lathing showed satisfactory results, but were hard work and handmade. On the other hand, with the rapid prototyping, prototypes were built with better finishing and were quicker. The utilization of rapid prototyping in the development of irrigation devices is something completely innovative and pioneering, besides being a tool of great utility in the product innovation in the Agricultural Engineering sector.

ABSTRACT Objective: To describe the use of three-dimensional prototyping or rapid prototyping in acrylic resin to create synthetic three-dimensional models in order to promote the understanding of bone deformities of the shoulder. Methods: Five patients were analyzed between ages of 11 and 73 years old, treated between 2008 and 2013 with glenohumeral deformities that required a more thorough review of the anatomical alterations, for whom three-dimensional prototyping was performed. Results: Patient 1 was treated conservatively and is awaiting humeral head arthroplasty if symptoms get worse. Patient 2 underwent a valgus proximal humerus osteotomy secured with pediatric locked hip plate according to a prior assessment with prototyping. Patient 3 underwent a disinsertion of the rotator cuff, tubercleplasty and posterior reinsertion of the rotator cuff. Patient 4 underwent an arthroscopic step-off resection, 360-degree capsulotomy, and tenolysis of the subscapularis. Patient 5 underwent a reverse shoulder arthroplasty with an L-shaped bone graft on the posterior glenoid. Conclusions: Rapid prototyping in acrylic resin allows a better preoperative planning in treatment of bone deformities in the shoulder, minimizing the risk of intraoperative complications in an attempt to improve the results.

complex-shaped architectures, digital modeling, physical modeling, rapid prototyping, project control, Architecture, NA1-9428, Architectural drawing and design, and NA2695-2793

La costruzione dell’architettura è preceduta, sempre più spesso, dalla costruzione del suo modello fisico e ciò dipende dalla complessità dalle forme geometriche che caratterizzano il progetto e dalla evoluzione delle tecniche di produzione dei modelli fisici. Per le geometrie dell’architettura contemporanea, molto variabili nel loro sviluppo tridimensionale, la rappresentazione sullo schermo piatto del computer risulta spesso insufficiente mentre il ricorso al loro modello fisico permette di cogliere a colpo d’occhio l’insieme del progetto e di verificarne meglio le forme. La realizzazione del modello comporta trasformazioni sostanziali del progetto architettonico con l’applicazione di nuove costruzioni geometriche del modello, del tutto peculiari, basate su un processo di estrema semplificazione delle forme. Si vuole qui documentare il lavoro didattico sviluppato nel corso di “Modellazione 3d”.

This paper shows an experience of the practical implementation of the Quadruple Helix-Based Innovation Model of Reference Sites of the European Commission through the Design Thinking method. This method establishes that, in order to successfully achieve the design of a digital solution, five unavoidable phases must be covered: empathize, define, ideate, prototype and test. The process was approached using the research action design. Qualitative data collection and analysis techniques were applied in each phase: qualitative meta-synthesis, focus groups, biographical interviews, professional and community forums and techniques of prototyping and testing with users. The systematic application of this method has facilitated the consolidation of a cooperative work model in which the main key agents in active and healthy ageing interact. Thus, products and services have been developed to better meet the needs of the users, making them an active part of the creation process.

Type 1 Diabetes Mellitus (DMT1) is currently one of the most harmful diseases that aect people of any age, including children from birth. Exogenous insulin injections remain the most common treatment for these patients, however, it is not the optimal one. The scientific community has endeavored to optimize insulin administration using electronic devices and thus improve the diabetics life expectancy. There are numerous limitations for this biomedical evolution to become a reality such as the control algorithms validation, experimentation with electronic devices, and applicability in patients age transcendence, among others. This work presents the prototyping of a neuro-fuzzy intelligent controller on the Texas Instruments LAUNCHXL-F28069M development board to form a hardware in the loop (HIL) scheme. That is, the embedded controller sends the insulin delivery rate data to the computer where it is captured by the Uva/Padova software and integrated into the metabolic simulation of virtual diabetic patients treated with an insulin pump. The main task of the embedded intelligent algorithm is to determine the optimal insulin infusion rate for each of the 30 virtual patients who follow a meal protocol. The novelty of this work focuses on overcoming current limitations through a first intelligent control algorithm approach applicable to artificial pancreas (AP) and analyzing the feasibility of this proposal in age transcendence since the results correspond to in-silico tests in populations of 10 adults, 10 adolescents and 10 children.

Control engineering systems. Automatic machinery (General) and TJ212-225

Resumen: Con el objetivo de alcanzar resultados satisfactorios en la enseñanza y puesta en práctica de cursos semestrales de ingeniería de control, en los que la presencia de alumnos de distintas disciplinas es más que notoria, se torna necesario recurrir a altos niveles de abstracción en la programación de los sistemas de control. Este alto nivel de abstracción procede del uso de un sistema de prototipado rápido para control de carácter avanzado, que permite recurrir a funcionalidades que no habían sido previstas en ningún entorno de prototipado rápido para control disponible con anterioridad. El carácter avanzado del sistema brinda soluciones desde el más alto nivel de abstracción, el denominado diseño basado en modelos, para las intricadas relaciones necesarias entre la ingeniería de control y la informática en tiempo real, permitiendo que los alumnos puedan centrar su esfuerzo en el desarrollo del algoritmo de control, la identificación de sistemas y el modelado de plantas físicas en lugar de preocuparse por las tediosas tareas de gestión y configuración a bajo nivel de la arquitectura hardware que están empleando. Gracias a este alto nivel de abstracción, que cubre el espectro abarcado por funcionalidades de muy bajo nivel y funcionalidades de muy alto nivel, el manejo del sistema propuesto se encuentra al alcance de audiencias multidisciplinares. El sistema avanzado de prototipado rápido para control se está empleando para cursos semestrales así como en multitud de Tesis de Máster y Doctorales. Abstract: In order to achieve successful results in the control courses for a multidisciplinary audience, a high abstraction layer at programming is required. This abstraction is provided by a custom developed rapid control prototyping system that enables the usage of model based design techniques to control real plants. Model based design is focused on the research and development of the control algorithm, system identification and plant modelling. The usage of the proposed embedded rapid control prototyping system eliminates completely the need for low level input/output control hardware configuration and debugging, making the system capable to be used by the intended multidisciplinary audience, since model based design focuses on design and analysis techniques and shows the relationships between control theory and real controller implementation issues. Several controllable real plants are ready to be used by students, from Bachelor, Master Thesis and Ph.D. degrees. They come from many engineering fields including mechanical, electrical... Also the common drawbacks of commercial rapid control prototyping systems are avoided thanks to the customized low cost rapid control prototyping system presented in this article.

Introduction and Objectives: The high variability of sinonasal anatomy requires the best knowledge of its three-dimensional (3D) conformation to perform surgery more safely and efficiently. The aim of the study was to validate the utility of Osirix® and stereolithography in improving endoscopic sinonasal surgery planning.
Methods: Osirix® was used as a viewer and Digital Imaging and Communications in Medicine (DICOM) 3D imaging manager to improve planning for 114 sinonasal endoscopic operations with polyposis (86) and chronic rhinosinusitis (CRS) (28). Stereolithography rapid prototyping was used for 7 frontoethmoidal mucoceles.
Results: Using Osirix® and stereolithography, a greater number of anatomical structures were identified and this was done faster, with a statistically-significant clinical-radiological correlation (P<.01) compared with 2D CT plates. With a share of more than 75% of surgery performed by residents, surgical time was reduced by 38±12.3min in CRS and 42±27.9 in sinonasal polyposis. The fourth-year residents reached 100% surgical competence in critical surgical milestones with 16 surgeries (CI 12-19).
Conclusions: The systematic use of Osirix® for visualisation and treatment of 3D sinonasal images from DICOM data files, along with the surgical team's ability to manipulate them as virtual reality, allows surgeons to perform endoscopic sinonasal surgery with greater confidence and in less time than using 2D images. Residents also achieve surgical competence faster, more safely and with fewer complications. This beneficial impact is increased when the surgical team has stereolithography rapid prototyping in more complex cases.

modular platform, conceptual design, sustainable design, cubesat, nanosatellite, design by factors, Motor vehicles. Aeronautics. Astronautics, TL1-4050, and Military Science

This article is intended to contribute to the development of proprietary technologies and the evaluation and selection of integrated technologies in the study of the aerospace concept necessary for the processes of technological appropriation. The problem addressed lies in the lack of modular platforms and lowcost test systems for experimental development and simulations of satellite systems. Therefore, compare to this the proposal of a scalable modular platform of the 1U CubeSat standard is presented as the main results. The design and characterization process presented from the concept of sustainability, contributes to the use and development of low-cost equipment that minimizes the impact on the environment and, in turn, is practical for its implementation in activities of groups and research centers that promote the diffusion of space technologies in Colombia. The methodology of sustainable design, the definition of design principles and conceptual design, which is materialized with the application of quality function deployment method (QFD), the theory of inventive problem solving (TRIZ)), the manufacturability-oriented design (DfM), assemblability (DfA), environmental impact (DfE), reliability (DfR), and safety assessment, are relevant for compliance with the CubeSat operating standards described in cds. Finally, several constructive modes of the low cost test platforms are proposed with different materials such as 3D prototyping in paper, abs, mdf wood and aluminum. All of them are small-scale satellite structures designed and constructed at low-cost. These designs result in the materialization to test on-board systems and integration resistance in assembly and materials, in laboratories as vibration test-bench, for research groups or companies interested in promoting the development of space technologies.
