Analysis and coordination of different mechanisms controlling tube elongation during the development of the embryonic system in Drosophila melanogaster
The tracheal (respiratory) system of the Drosophila embryo is a network of interconnected epithelial tubes that supplies and exchanges the gas to maintain the homeostasis of the entire organism. Maintaining a controlled ...
Analysis and degradation mechanisms of enamels, grisailles and silver stains on Modernist stained glass.
Materials and methods used in the production of modernist (late 19th and early 20th century) stained glass from the city of Barcelona with special regards to the degradation mechanisms of enamels, grisailles and silver ...
Analysis and design of a capillary driven blood plasma separation microfluidic device
Recently, the emergence of lab-on-a-chip devices has seen in a variety of applications especially in clinical analys is and diagnostics. ln particular the lack of suitable microdevices for separation of plasma from whole ...
Analysis and design of an edge-technique-based Doppler wind lidar: practical assessment of a laboratory prototype
This thesis is the initial stage in the development of a range-resolving Doppler wind lidar. Atmospheric lidars emit pulsed laser radiation that after being scattered by air molecules and suspended aerosol particles is ...
Analysis and Design of Bulk Acoustic Wave Filters Based on Acoustically Coupled Resonators
El ràpid creixement dels sistemes de telecomunicacions sense fils ha portat a una creixent demanda de dispositius mòbils amb requisits cada vegada més estrictes per als filtres de microones incloent un millor rendiment, ...
Analysis and design of fault tolerant axial flux permanent magnet synchronous motors
Electric vehicles (EVs) are attractive comparted to internal combustion engine powered vehicles due to several benefits, including low emissions, higher efficiency, less maintenance costs, stronger acceleration or lower ...
Analysis and design of heating systems for advanced automotive Radomes
The main purpose of this thesis is to study how we could obtain a transparent heating system for a Radome. In the context of this thesis, transparent have two different meanings that are tied due to the objective of our ...
Analysis and design of real-time control systems with varying control timing constraints
L'anàlisi i el disseny dels sistemes de control de temps real és una tasca complexa, que requereix la integració de dues disciplines, la dels sistemes de control i la dels sistemes de temps real. Tradicionalment però, els ...
Analysis and Development of a Platform for Generating Context-Aware Apps for Mental Health
This work gathers a research carried out on the use of context-aware technologies in their application to the field of mental health. It starts performing a review of mobile technologies used in psychological interventions ...
Analysis and development of experimental characterization methodologies of mode II fracture toughness on CFRP bonded joints
Adhesives have been shown to be an excellent solution for joining fibre reinforced polymer (FRP) components thanks to their capacity to redistribute loads, reduces stress concentrations and contribute to overall weight ...
Analysis and Evaluation of Climate Change Policies and their Interaction with Technological Change
The core analysis of this work is divided in three different but thematically related studies, analysing, first, how climate change policies can help to limiting global warming and one of its direct causes, the emission ...
Analysis and impact of antibiotics in marine organisms. Laboratory experiments and field studies
Antibiotic residues in the environment are amongst the most concerning micropollutants due to their potential impact on the natural ecosystems and human health. In this thesis, laboratory and field studies were conducted ...
