In this thesis, the interaction between flow and sediment in alluvial channels is studied from an empirical approach, for conditions close or pertaining to supercritical flow, and for four types of sediment: sand, gravel ...
The technological era that we live in is sometimes described as the Information Age. Colossal amounts of data are generated every day and considerable effort is put into creating technologies to process, store and transmit ...
The main aim of this thesis is the study of the Bernstein-Sato polynomial of plane curve singularities. In this context, we prove a conjecture posed by Yano about the generic b-exponents of a plane irreducible curve. In ...
A new thin shell finite element is presented. This new element doesn’ t have rotational degrees of freedom. Instead, in order to overcome the C1 continuity requirement across elements, the author resorts to enhance the ...
In this thesis we develop and analyse mathematical models describing phase change phenomena linked with novel technological applications. The models are based on modifications to standard phase change theory. The mathematical ...
Leakage is a widespread problem associated with the construction of diaphragm walls whenever they are erected in water-bearing ground. The aim of the present research is to develop a new type of slurry wall: the bi-layer ...
Este trabajo está dividido en dos partes claramente diferenciadas, ambas dentro de la Física no lineal.<br/>La primera es un estudio de las inestabilidades de la corriente en semiconductores extrinsecos, incluyendo ...
We are at a stage where Building Information Modelling (BIM) has reached a maturity level to be widely adopted by the professionals and organizations within the Architectural, Engineering and Construction (AEC) industry. ...
The introduction of Building Information Modeling (BIM) is changing the work environment in the AEC industry. Many countries require the AEC industry to submit building documentation using BIM. For example BIM is a requirement ...
In our culture, robots have been in novels and cinema for a long time, but it has been specially in the last two decades when the improvements in hardware - better computational power and components - and advances in ...
Dos de las limitaciones de rendimiento más importantes en los procesadores de hoy en día provienen de las operaciones de memoria y de las dependencias de control. Para resolver estos problemas, las memorias cache y los ...
As new promising alternatives, novel bio-based materials are already developed to apply in construction sectors due to biodegradability, low toxicity, sustainability, renewability, and acceptable general properties. However, ...
Polyesters are extremely versatile polymers which can be used in a wide variety of applications ranging from high performance materials to recyclable and degradable polymers. The preparation of polyesters from renewable ...
(English) One of the most exploited tissue-engineering-based strategies nowadays is to use scaffolds that allow local stimulation of the targeted tissues, increasing therapy effectiveness while reducing toxicity. Therefore, ...
La presente tesis es una reflexión sobre la adecuación bioclimática de la experiencia arquitectónica catalana, heredera del movimiento moderno en el campo de la vivienda, persiguiendo dos objetivos concretos: por ...
Increasing quantities of organic pollutants (OP) are being released to the environment, posing a threat to Earth’s life system. In the marine environment, OP pollution caused by oil spill accidents receives a lot of academic ...
Biofiltration has become an effective and economical alternative to traditional gas treatment systems. High costs of operation and energy consumption associated to conventional treatments have lead to increase the attention ...
To obtain a regeneration and integration of gingival tissues onto the dental implant surface, is essential to achieve an appropriate cellular response. To promote an appropriate cellular response, materials surface has ...
Energy for cooking is the most essential energy service for peasants in countries with tropical climates such as Colombia where a large number of families can only access to firewood as energy source. An alternative energy ...
Humanity is currently using more than 200000 synthetic organic compounds in many industrial, agricultural and domestic applications. Many of these chemicals reach the environment and have a harmful effect on ecosystems and ...
