Gráficos en investigación y diseño
Inegraf (1994)En este trabajo se aborda el estudio genérico de los procesos de investigación y diseño, con la intención de revisar las diferencias y semejanzas entre ambos, en cuanto al empleo de herramientas gráficas. La principal ... -
La proyección en el proceso de representación y en los sistemas de representación
Inegraf (1995)En este trabajo se aborda el estudio genérico de la aplicación del proceso de representación, tanto en los sistemas «clásicos» de representación, como en los algoritmos de representación por ordenador. Se pretende poner ... -
Reconstrucción Geométrica Tridimensional
Inegraf (1996)A pesar de los importantes avances en CAD, los diseñadores todavía prefieren el lápiz yel papel. Especialmente en las fases más conceptuales del diseño, en las que se baraja unacolección incompleta de requisitos e ideas ... -
Product Data Quality and Collaborative Engineering
IEEE Computer Society (2002-05)n this article, the authors analyze the impact of product data quality in the implementation of collaborative engineering in an extended enterprise framework. They also analyze the product data model as a key element for ... -
Situación Actual de la Reconstrucción 3D de Dibujos Lineales
Centro de Informacion Tecnologica (2004)The present study summarizes the studies made on the three-dimensional reconstruction of linear drawings over the last thirty years, making a critical evaluation of different methods and current tendencies. A new general ... -
Integrated modeling with Top-Down approach in subsidiary industries
Elsevier (2004-01)This article considers how conceptual design of industrial products is supported by current CAD systems. The case of subsidiary industries, or first tier suppliers, that must simultaneously deal with different customers ... -
An optimisation-based reconstruction engine for 3D modelling by sketching
Elsevier (2004-12)An engine that automatically reconstructs a large variety of polyhedral, origami and wire-frame objects from single-view sketched drawings generated in a calligraphic interface is presented. The engine has two stages. An ... -
Educational software for teaching drawing-based conceptual design skills
Wiley (2004-12-17)An education-oriented computer application to draw sketches of polyhedrons that are automatically recognized to reconstructs the suitable three-dimensional (3D) models is presented. The users can modify the sketches and ... -
Improving Visualization Skills in Engineering Education
IEEE Computer Society (2005-09)This article analyzes the importance of visualization skills in engineering education. It proposes a dual approach based on computer graphics applications using both Web-based graphic applications and a sketch based modeling ... -
Semantic Differential applied to the evaluation of machine tool design
Elsevier (2005-11)In this article, a study is presented showing that Product Semantics (PS) can be used to study the design of machine tools. Nowadays, different approaches to PS (Semantic Differential, Kansei Engineering, etc.) are being ... -
A survey on geometrical reconstruction as a core technology to sketch-based modeling
Elsevier (2005-12)In this work, the background and evolution of three-dimensional reconstruction of line drawings during the last 30 years is discussed. A new general taxonomy is proposed to make apparent and discuss the historical evolution ... -
Learning Support Tools for Developing Spatial Abilities in Engineering Design
Tempus Publications (2006)This paper presents some learning support tools for developing spatial abilities in engineering design students. They are based on the previous authors' experience in teaching traditional Engineering Graphics and uses both ... -
Flow structure of gas-liquid two-phase flow in an annulus
Elsevier (2008)The flow structure of gas-liquid two-phase flow in vertical annulus channel has been investigated. The inner and outer diameters of the annular channel were 19.1 and 38.1 mm, respectively. The total height of the test ... -
Design of a model to assess the environmental risk of leachate dams
Elsevier (2008)Leachate dams store very toxic liquids, leachate, that contain a large amount of pollutant substances. Most of them are located in gullies or ravines, so if a dam breaks, leachate would advance downstream provoking an ... -
Upward vertical two-phase flow local flow regime identification using neural network techniques
Elsevier (2008)Traditionally, the flow regimes in two-phase flow are considered in a global sense. However, a local flow regime is required to understand and model the interfacial structures present in the flow. In this work, a new ... -
Interfacial area transport of vertical upward air-water two-phase flow in an annulus channel
Elsevier (2008)An experimental study on the interfacial area transport (IAT) of vertical, upward, air-water two-phase flows in an annulus channel has been conducted. The inner and outer diameters of the annular channel were 19.1 mm and ... -
A dynamic model of a shell-and-tube condenser operating in a vapour compression refrigeration plant
Elsevier (2008)This work presents a mathematical model of a shell-and-tube condenser based on mass continuity, energy conservation and heat transfer physical fundamentals, whose methodology can be easily adapted for modelling any type ... -
