Opposable reasons: solving conflicts of fundamental rights and norms
This dissertation argues that the deadlock that constitutional courts find themselves in when justifying decisions on cases that involve conflicting constitutional norms can be best resolved by appealing to a particular ...
Optical and visual characterization of multifocal contact lenses and multifocal intraocular lenses
Vision is presented and universally accepted as the most precious of the human senses.lt is structured in three main parts: the optical system {eye), the photo-sensor {eye's retina), and the data processor (brain). If one ...
Optical antennas control light emission
The emission of light is at the heart of both fundamental science and technological applications. At its origin lie electronic transitions in nanoscale materials such as molecules, atoms and semiconductors. The interaction ...
Optical antennas for single emitters
The interaction of light with matter is a central topic in both fundamental science and applied technology. At the heart of this interaction lies the absorption or emission of a photon by an electronic transition in for ...
Optical control of endogenous receptors and cellular excitability with light
Light-controlled manipulation of neuronal activity has transformed the field of neurobiology. Light provides temporal and spatial resolution over activation or inhibition of targeted populations of neurons, one single ...
Optical detection and structural analysis of DNA via direct surface-enhanced Raman scattering
Un nou mètode basat en la espectroscopia Raman intensificada per superfície (SERS) és implementat en aquesta tesi per a la detecció òptica i anàlisi estructural d'àcids nucleics. Aquest mètode es basa en la utilització de ...
Optical Flow in Driver Assistance Systems
El moviment és un atribut perceptiu del cervell humà molt important. La percepció visual que fa el cervell del moviment és el procés d’inferir la velocitat i direcció dels elements d’un escenari mitjançant entrades visuals. ...
Optical flow: related problems
Motion estimation plays a key role in many of the image processing and computer vision problems. This thesis addresses the problem of recovering a dense motion field from a scene through the Calculus of Variations. In ...
Optical grating coupler biosensor and biomedical applications
Biosensors are nowadays a powerful tool to enable the detection of specific biological interactions and to evaluate the concentration dependence in the response. A biosensor usually consists of three different parts: the ...
Optical holographic microscopy for bio- and nanoparticle characterization
(English) Nowadays, being able to precisely characterize nanoparticles is of key relevance in a wide range of scenarios. For instance, chemical and pharmaceutical industries often rely in particle-sizing for quality control. ...
