Cortés Sáenz, David; Gordillo Castillo, Nelly; Riba Romeva, Carles; Lloveras Macià, Joaquín
This work presents a methodology for the selection and comparison of non-traditional sheet metal cutting processes as a new structure of selection by means of an expert system. The model is generated from a knowledge base acquired from diverse experts, and the use of fuzzy logic techniques. With a simple input of the parameters of a piece, the system offers the most appropriate cutting options (based on the requirements of the piece) allowing a non-expert user selecting the most appropriate process with emphasis on a predefined priority: finish, cost or time. The selection process consists of four base algorithms that measure the attributes of each process as a dependent indicator of the other processes, that is, a pre-selection that considers (1) the process capability to cut a material-thickness relation, (2) the speed that can be achieved with this relation, (3) the inherent complexity of the piece to be cut, and (4) the process tolerance. Results of experiments under three different approaches prove that the expert system here presented accurately prioritizes the most convenient cutting processes.

El presente artículo explora sectores que identifican la innovación en empresas farmacéuticas de España. Para ello se consideran firmas nacionales y filiales extranjeras establecidas en territorio nacional. El análisis realizado comprende el periodo de 2009 al 2011 para una población N=200 empresas afiliadas en ese momento a Farmaindustria y al Plan Profarma. El trabajo consistió en una búsqueda de información útil en las páginas web de las empresas farmacéuticas establecidas en España que pudieran describir de forma estática el perfil innovador del sector farmacéutico español a través del análisis estadístico descriptivo. De esta forma, se crea un cimiento para la documentación de los resultados en una base de datos con el propósito de obtener un panorama con determinación sobre el comportamiento del sector farmacéutico español, así como posibles tendencias.
El alto contenido de aportación literaria sobre el sector farmacéutico, se expresa de forma globalizada a nivel nacional e internacional, desestimando datos e información que pudieran ofrecer señales de amenaza u oportunidad respecto al corto periodo de tiempo, ya que a su vez son equiparables a otros años puesto que la industria farmacéutica española se constituye por empresas de origen extranjero (50.5%) y de capital nacional (49.5%). De éstas últimas las pymes son las protagonistas de las pequeñas innovaciones de las firmas establecidas en Madrid y Barcelona principalmente.

S’exposen algunes metodologies practicades a classe, com per exemple que: els estudiants s’organitzen en grups i trien el seu tema de treball; usen tècniques de creativitat per fer innovacions; en les presentacions orals s’organitzen també preguntes entre ells.

Gual Ortí, Jaume; Puyuelo Cazorla, Marina; Lloveras Macià, Joaquín
Point, linear and areal elements, which are two-dimensional and of a graphic nature, are the morphological elements employed when designing tactile maps and symbols for visually impaired users.
However, beyond the two-dimensional domain, there is a fourth group of elements - volumetric elements - which mapmakers do not take sufficiently into account when it comes to designing tactile maps and symbols.
This study analyses the effect of including volumetric, or 3D, symbols within a tactile map. In order to do so, the researchers compared two tactile maps. One of them uses only two-dimensional elements and is produced using thermoforming, one of the most popular systems in this field, while the other includes volumetric symbols, thus highlighting the possibilities opened up by 3D printing, a new area of production.
The results of the study show that including 3D symbols improves the efficiency and autonomous use of these products.

Gual Ortí, Jaume; Puyuelo, Marina; Lloveras Macià, Joaquín
The aim of this article is to determine whether the process of memorizing a tactile map key, or legend, can be improved by including three-dimensional (3D) symbols produced by means of 3D Printing. The method used in this study involved asking a group of 20 volunteers with different profiles to memorize eight tactile symbols from two keys, each of which had different characteristics: Key 2 included 3D tactile symbols and Key 1 had only two-dimensional (2D) tactile symbols. Results show statistically significant differences between the two keys. Use of Key 2 yielded a 48.72% reduction in the number of errors compared to Key 1 (N = 20, p-value = .014). These data show that combining 3D with flat relief symbols (2D) improves the process of memorizing a tactile key because the 3D attributes can be distinguished from the 2D features by touch. For practitioners, this article provides data about the possibilities of 3D Printing applied to tactile maps, keys, and symbols.

This paper shows an experiment with tactile maps designed for visually impaired persons. Tests were carried out on a tactile map produced with 3D printing and including a new type of tactile symbols, volumetric symbols (3D). These symbols are localized faster than conventional flat relief symbols, with the same error rate, an improvement in the use of these tactile devices. Moreover, following tests, differences were found between types of participants with blind participants generally carrying out the proposed tasks better than the rest of users

First responders, including structural engineers and firefighters, inspect buildings and identify the structural
integrity of buildings within a disaster affected area. The performance of their inspection and dissemination
of the assessment information are critical to Urban Search and Rescue (US&R) operations.
This paper presents an innovative approach for structural assessment and resource requests through
an application – Supporting Urban Preparedness and Emergency Response using Mobile Ad hoc Network
(SUPER-MAN). The goal of this research is to address challenges encountered in the current practice for
structural engineers and first responders to inspect and disseminate building damage assessments and
resource requests more efficiently to support US&R. The SUPER-MAN system is equipped with Radio Frequency
Identification (RFID) tags, as the storage device of assessment information on the disaster site,
and a Mobile Ad hoc Network (MANET) with a Dynamic Source Routing (DSR) implementation for communication.
SUPER-MAN strengthens responders’ situational awareness, reduces confusion of inconsistent
assessment formats, and automates information dissemination and editing. As a result, lifesaving
operations are adequately prioritized, risk of first responders are minimized, and requests of response
resources are facilitated. Results obtained from field trials carried out at the Illinois Fire Service Institute
with a simulated disaster scenario and computer simulations of the MANET are presented to highlight the
benefits provided by SUPER-MAN.

Las técnicas de vigilancia, inteligencia y prospección tecnológi-ca buscan capturar, asimilar y aplicar el conocimiento, recurriéndose con gran frecuencia a los diagramas. Para conocer cómo la transferencia de conocimiento puede estimular o bloquear el proceso creativo se diseñó una investigación experimental, buscando analizar el estado de la técnica y aportar nuevos caminos para la manifestación visual del conocimiento para mejorar e incrementar la calidad y cantidad de respuestas individuales o colectivas en las diferentes etapas del proceso creativo. El impacto de los distintos tipos de diagramas se midió utilizando el test de inteligencia creativa CREA. Se ha obtenido que el diagrama de tipo conexión, que es el menos frecuente, presenta los mejores resultados para estimular la creati-vidad. El análisis de dos casos de aplicación para encontrar alternativas para el desarrollo de productos, procesos y servicios tecnológicos, corro-bora los buenos resultados que se obtienen de la combinación del método Delphi, para efectuar la prospección tecnológica, y los mapas mentales como diagrama con estructuras de conexión.
