The creation of a binaural spatialization tool

The main focus of the research presented within this thesis is, as the title suggests, binaural spatialization. Binaural technology and, especially, the binaural recording technique are not particu-larly recent. Nevertheless, the interest in this technology has lately become substantial due to the increase in the calculation power of personal computers, which started to allow the complete and accurate real-time simulation of three-dimensional sound-fields over headphones. The goals of this body of research have been determined in order to provide elements of novelty and of contribution to the state of the art in the field of binaural spatialization. A brief summary of these is found in the following list: • The development and implementation of a binaural spatialization technique with Distance Simulation, based on the individual simulation of the distance cues and Binaural Reverb, in turn based on the weighted mix between the signals convolved with the different HRIR and BRIR sets; • The development and implementation of a characterization process for modifying a BRIR set in order to simulate different environments with different characteristics in terms of frequency response and reverb time; • The creation of a real-time and offline binaural spatialization application, imple-menting the techniques cited in the previous points, and including a set of multichannel(and Ambisonics)-to-binaural conversion tools. • The performance of a perceptual evaluation stage to verify the effectiveness, realism, and quality of the techniques developed, and • The application and use of the developed tools within both scientific and artistic “case studies”. In the following chapters, sections, and subsections, the research performed between January 2006 and March 2010 will be described, outlining the different stages before, during, and after the development of the software platform, analysing the results of the perceptual evaluations and drawing conclusions that could, in the future, be considered the starting point for new and innovative research projects

Connected Attribute Filtering Based on Contour Smoothness

A new attribute measuring the contour smoothness of 2-D objects is presented in the context of morphological attribute filtering. The attribute is based on the ratio of the circularity and non-compactness, and has a maximum of 1 for a perfect circle. It decreases as the object boundary becomes irregular. Computation on hierarchical image representation structures relies on five auxiliary data members and is rapid. Contour smoothness is a suitable descriptor for detecting and discriminating man-made structures from other image features. An example is demonstrated on a very-high-resolution satellite image using connected pattern spectra and the switchboard platform

Microfluidic-based analysis of 3D cell migration under different biophysical and chemical gradients

Several mechanochemical factors are involved in cell migration, fundamental to establish and maintain the proper organization of multicellular organisms. The alteration of migratory patterns of cells could be related to the development of several pathologies. Focusing this work on tissue regeneration, more specifically wound healing, bone regeneration and blood vessel formation, the main aim of this work is to advance in the understanding of how chemical or physical factors present in the cell niche can regulate the cell movement (fibroblasts, osteoblasts and endothelial cells respectively). In an effort to understand what mechanisms are involved, it has been seen that both the extracellular matrix surrounding tissue cells and the biomolecules present in the cellular microenvironment can affect the behavior of cells [1–3]. In turn, interstitial fluid flow, defined as the convective transport of liquids through the extracellular matrix of tissue, is also capable of altering the morphology and cellular movement. Similarly, biomolecules, such as growth factors or drugs, modify the migration pattern. The main mechanisms studied throughout this thesis have been chemotaxis, durotaxis and rheotaxis. The biological processes for which these analyses have been performed were angiogenesis, wound healing and bone regeneration respectively. For the in vitro study of these variables, and making use of novel microfabrication techniques such as microfluidics, new platforms for 3D cell culture have been developed [4,5]. The microfluidic chips used allow replication of the ex vivo tissue microenvironment through the use of hydrogels and the generation of concentration gradients and controlled fluid flows. It should be noted that the versatility of this technology has allowed us to simultaneously study several microenvironmental factors, such as chemical gradients and matrix stiffness applied to fibroblast culture to understand its behavior in the wound area. In addition, these types of systems allow the visualization and/or monitoring of the cellular response in real time, being able to quantify the cellular migration. For the application of fluid flow, a novel system was designed to avoid the rupture of the hydrogels, allowing to obtain a stable interstitial flow inside the chip chamber. Throughout this thesis, it has been seen that there are several factors involved in 3D cell migration. Not only variables such as the chemical gradient (studied in endothelial cells and fibroblasts) or the rigidity of the extracellular matrix (analyzed in fibroblasts and osteoblasts) affect cells [6,7]. The architecture of the matrix, more specifically the disposition of the fibers that conform this matrix, has been identified as playing an important role in cell migration, also altering the morphology of cells, in this case osteoblasts.[1] N.

Order and structure in syntax I

This book reconsiders the role of order and structure in syntax, focusing on fundamental issues such as word order and grammatical functions. The first group of papers in the collection asks what word order can tell us about syntactic structure, using evidence from V2, object shift, word order gaps and different kinds of movement. The second group of papers all address the issue of subjecthood in some way, and examine how certain subject properties vary across languages: expression of subjects, expletive subjects, quirky and locative subjects. All of the papers address in some way the tension between modelling what can vary across languages whilst improving our understanding of what might be universal to human language
