REQUIREMENTS engineering, COMPUTER software development, LITERATURE reviews, VEINS, NATURAL languages, and SPECIFICATIONS
This paper presents a literature review about alternatives for determination of requirements in software development projects. The literature searching begins from a fundamental principle, request information about methods of determination of requirements that do not need a high percentage of interaction with users or customers. This usually happens because users or customers don't have time as it happens when traditional methods are used. The search for information was made taking into account the low interaction with the user or customer and in this vein, it was needed to expand the search horizon until 2000 and it includes classic texts in the study area. The search results provided insights about the techniques of requirements engineering, whose main characteristic is to minimize the interaction with users, such as, prototyping, document analysis and legacy software which are the closest ones to the search condition.

In industrial design, aeronautical technologies are not usually addressed, nor are they incorporated as teaching exercises in laboratories. The economic and technological variables make it difficult to carry out the academic intervention of industrial design, in the aeronautical design due to the lack of resources and specialized facilities. However, the emergence of parametric computer programs, aimed at users with little experience in calculation, the access to rapid prototyping technologies and the availability of low-cost high-tech materials, have enabled the design and construction of a primary ultra light glider, as an experimental academic experience of the School of Design of the University of Chile. The competition of amateur gliders called Flugtag, sponsored by a recognized brand of energetic drinks, arose as the perfect opportunity for the development of a flying vehicle and also as a challenge to open a potential development area at the school of design. This work should be understood as a first approach to the design of primary aircraft, assisted with software, which is based on the preliminary experience that the academic group has developed in the design and construction of land vehicles. The process generated many more questions rather than certainties, which in turn, will allow to address a second project with more expertise and better track of all stages of construction and testing.

RAPID prototyping, CRANIAL manipulation, SURGERY, TOMOGRAPHY, and IMAGE processing
This article presents a description of Rapid Prototipyng (RP) technology applied to medicine, especially to craniofacial problems, which can produce solid 3D models by adding material. At the same time, describes a specific application from the simulation surgery to insert four screws, which are the basis of a fixed prosthesis supported by implants. The surgical procedure simulation, started with obtaining the mandibular geometry from biomedical image processing of computerized axial tomography (TAC) of an adult woman, totally edentulous. This process was carried out using GIB Points 3D software, developed in this work, with which A 3D cloud point of jaw was obtained, and subsequently exported to ProEngineer Wildfire 3.0. From here, a STL file compatible with most RP machines was created. The technology used for 3D printing, was Fused Deposition Modeling (FDM). A 3D plastic model of jaw, with anatomical and dimensional high quality, using technology available in Colombia was obtained. In addition, it successfully simulated surgical procedure for the installation of four implants using the tools to be used in real surgery. In general, the implemented methodology can be used for surgical planning procedures and thus avoid trial and error test, that might put the patient's health at risk. Also as a communication tool to explain to the patient surgical procedures to be submitted. In addition, it can be used for educational purposes, for training students, making more effective learning processes in the clinical field, which in turn would result in better outcomes for patients.

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.

ELECTRIC controllers, RAPID control prototyping, CASCADE converters, HYSTERESIS loop, SINUSOIDAL projection (Cartography), and AMPLITUDE modulation
In this work, we analysed the behaviour of a buck-boost electronic converter. The objective of the zero hysteresis controller is to track user defined sinusoidal signals, usually featuring high power level and variable frequency, amplitude and wave form. The controller was implemented in the laboratory, where load and reference signal disturbances were introduced. The controller achieved a fast and adequate behaviour. The converter was implemented using a half bridge monophasic inverter, and a rapid control prototyping (RCP) DS1104 in real time for the control task. [ABSTRACT FROM AUTHOR]
Digital Manufacturing Technologies (DMT) are a set of emerging technologies that allow to realize a model, a prototype or a small series directly from a CAD 3D digital file and a wide range of techniques, materials and finishes. The aim of this paper is to present the characteristics, advantages and opportunities of DMT for the construction of models, prototypes and small series in the context of design and product development. The study analyzes the state of the art of Additive Digital Manufacturing Technologies, the most advanced and recent technologies in their category, which have driven a lot of progress in the prototyping techniques, with never-before-seen possibilities, with advantages such as direct and immediate manufacture, generating forms with complex geometries impossible to be made with traditional technologies, high degree of accuracy, manufacture of armed assemblies and integration of different materials in a single process (multimaterial), among others. Finally, an analysis about how these technologies are radically changing the paradigms in the designing-prototyping-validating process is made, in comparison with traditional prototyping and manufacturing techniques.

This paper describes the designing and manufacturing process of jewelry products which primary raw materials are natural structures from endangered Colombian indigenous species. This collection was motivated by the morphology of the carranchina turtle, the Chicamocha wren and the deer horn coral. The first stage is formal analysis and geometrization of a natural structure in order to obtain units that allow defining the product's dimension and shape. Next, there is the digital molding and the creation of parametric geometries by means of tools such as Rhinoceros® and Grasshopper®. As a result, it is possible to control the design category, with the opportunity to generate several formal alternatives with high levels of accuracy and complexity. Furthermore, the parametric molding helps to the manufacturing of jewelry products, since it gives high accuracy in the prototyping of wax models, which are subsequently processed through microfusion in order to get the final jewelry.

AUGMENTED reality, EDUCATIONAL resources, COURSEWARE, TEACHERS, and MOTIVATION (Psychology)
Given its characteristics, augmented reality (AR) is presented as an alternative resource in a virtual learning environment (VLE) by providing virtual elements in the real world, which can facilitate learning. This article aims to describe the development of a mobile application with guided AR under the fundamentals of User-Centered Design (UCD) in order to be integrated into a VLE. The development strategy consisted of using the UCD and in its phases making use of tools such as: surveys for the collection of information, Quality Function Deployment to identify and prioritize requirements, AR technology for prototyping and finally usability tests to identify design problems. As a result, it was possible to demonstrate the viability of this procedure in the development of interfaces of this type, considering that the resources that contextualize the needs and tastes of its users can provide better facilities and motivation within their learning. The case study studied is that of English for primary school children, which allowed verifying that this detailed framework can be replicated to other areas of interest and allow teachers to integrate AR applications in face-to-face or online learning environments.
