Background and objective: Measuring the thickness of cortical bone tissue helps diagnose bone diseases or monitor the progress of different treatments. This type of measurement can be performed visually from CAT images by a radiologist or by semi-automatic algorithms from Hounsfield values. This article proposes a mechanism capable of measuring th...

Wear debris in total hip arthroplasty is one of the main causes of loosening and failure, and the optimal acetabular fixation for primary total hip arthroplasty is still controversial because there is no significant difference between cemented and uncemented types for long-term clinical and functional outcome. To assess and predict, from a theoreti...

The wear rate on Total Hip Arthroplasty (THA) entails a heavy burden for patients. This becomes more relevant with increased wear risk and its consequences such as osteolysis. In addition, osteolysis has been described in cemented and uncemented acetabular implants, and nowadays, controversy remains as to whether or not to cement the acetabular com...

This paper summarizes the research results of a doctoral thesis that arises from the perception of a particular state of discomfort in the feeling of some university students of Architecture from several Schools of Spain. The crisis situation leads many qualified professionals in the field of construction to expand their university studies and with...

Lecture about the last high technology in radiant systems. Moderated by Enrique Yotti, Vice-president of ASHRAE Spain Chapter.

Statistical analysis of 907 surveys of architecture students and their teachers through the so-called Empathic Survey, in order to analyze the emotional divergences between teachers and students and its impact on learning, have exposed an abnormal and unexpected effect, contradictory to the underlying assumptions. Initially it was hoped that the gr...

This presentation for the Climatization fair in 2015 shows the last research about R3F radiant systems

Presentation at Technical Conferences in IFEMA Madrid. Graphics parameters fo the R3F system (Raised Removable Radiant Floor)

Since the publication of Emotional Learning Method (ELM) in 2011, which was marked vertebral lines working in university teaching using emotional techniques, some data have been obtained and some interesting results that support the high potential of this method, personal knowledge and academic results oriented. In this paper we have researched on...

The main objective of this paper is to analyze the behaviour of cold formed steel cross section respect to mechanical characteristics, such as deflection, mainly. A cold formed steel profile with thickness of 1 mm regards is studied to determine its viability as reinforcement of timber upgrading. Thus, temperatures, stresses and strains have been a...

The aim of this paper is to study the mechanical capacity improvement in a cold formed steel cross section with thickness of 1 mm regards to a cross section made by means of hot-rolled steel with thickness of 4 mm, respectively. Likewise, the differences are studied in the manufacturing processes used in both profiles, and the particularities of co...

The teachings of Architecture in Spain have undergone significant changes in the legislative environment in the last 50 years. The formation of Architecture, based mostly in the workshop format, is an element of coordination between different learning techniques. This paper presents an approach to an Emotional Learning Method (ELM), which aims to i...

Las enseñanzas de Arquitectura en España han sufrido, en los últimos 50 años, cambios normativos que han hecho variar, alternativamente, la duración de los estudios desde los 5 a los 6 años. Actualmente con la aprobación de los planes de estudio y su adaptación al Espacio Europeo de Educación Superior (EEES), volvemos a los 6 años al poseer las com...

LAS BAJAS TEMPERATURAS QUE LA CATEDRAL DE BURGOS sufre durante los meses de invierno han sido el detonan-te para que el Cabildo del templo decidiera incorporar a este monumento histórico artístico algún sistema que le permitiera un acondicionamiento térmico óptbno. A pesar de ser una iniciativa demandada desde hace años, lo cierto es que la interve...

The purpose of this study is to determine the stress distribution in the joint carpenter of halved and tabled joint with the finite element method and its comparison with the values obtained using the theory of Strength of Materials. The stress concentration areas where analyzed and the influence of mesh refinement was studied on the results in ord...

Se describe un procedimiento para la consolidación de viguetas de forjado de madera con deterioro en las cabezas mediante perfiles de acero conectados a la madera desde la cara superior del forjado. La pieza de refuerzo es un perfil en U de acero S275 conformado en frío con pletinas soldadas insertadas en la madera y conectada mediante tirafondos....

This paper describes the design of a procedure for the upgrading of timber floor joists with decayed ends using steel profiles connected to timber from the upper side of the flooring. The reinforcement consists on a steel S275 U cold formed shape with a plate inserted into timber and connected by means of screwing into the wood. For the experimenta...

Hoy en día, la construcción con estructura de madera, concretamente en forjados, se ex-tienden por todo el territorio nacional a través de edificios pertenecientes, tanto a Patrimo-nio, como al uso de vivienda ubicada en cas-cos históricos de ciudades. Pese a las políticas de concienciación guber-namental respecto de la conservación de bienes inmue...

A procedure for the reinforcement of timber floor joists in ancient buildings using steel U shape cross sections screwed to timber from the upper side is described. Bending tests of 3 groups of 10 beams were carried out obtaining the stiffness and load carrying capacity. The first one was composed by pieces of glued laminated timber of Spruce with...

This research paper provides relevant statistical equations (linear regression models) and grading procedures, in order to estimate density in members during the assessment of existing timber structures. A total amount of 266 structural coniferous pieces of different cross-sections and species, have been tested to establish best prediction paramete...

This paper describes the reinforcement of timber floor joists in old buildings using steel cross-sections connected to timber from the upper side of the flooring. The reinforcement consists of a U-shaped steel cross-section with plates inserted into the timber and connected by means of screwing. For experimental verification 30 beams were tested by...

The primary target of this Thesis is the design of a constructive procedure for the reinforcement and consolidation of lumber in wood floor slabs of ancient buildings using metallic profiles that settle from the superior face of the floor. The system has two differentiated applications affluent that are analyzed in this work. First, it is the reinf...

RESUMEN El objetivo principal de esta Tesis es el diseño de un procedimiento constructivo para el refuerzo y consolidación de viguetas de madera en forjados de edificios antiguos utilizando perfiles metálicos que se instalan desde la cara superior del piso.
