Image morphological processing
… important in today's technology. Mathematical Morphological operations, which are based on set theory, can extract object features by suitably shaped structuring elements. Mathematical Morphological filters are combinations of morphological operations that transform an image into a quantitative …

Soft Morphological Computation
… thesis proposes and supports the theory of Soft Morphological Computation (SoMComp), by which a soft robot should appropriately condition, or ‘affect’, the soft interactions to improve the quality of the physical stimuli arising from it. SoMComp is composed of four main principles, i.e.: Soft …

Unsupervised Morphological Word Clustering
… of a given lexicon into conflation sets (sets of morphologically related words). The word clustering is based on clustering of suffixes, which, in turn, is based on stem-suffix co-occurrence frequencies. The suffix clustering is performed as a clique clustering of a weighted undirected graph with …

Morphological plasticity of astrocytes
Studies of the central nervous system plasticity have concentrated on synaptic and neuronal changes and often ignored the role that glial cells play in interneuronal communication. Current research has begun to examine one type of glial cell, the astrocyte. Astrocytes are involved in the regulation …

Morphological Study of Dendritic Spines
Reconstruction of the neuron structure and the characterisation of dendritic spines is nowadays a hot topic in neurobiology research. Dendrites are cellular structures whose main objective is to conduct the electrochemical stimulation received from other neural cells to the cell body of the neuron …

Morphological granulometry for texture analysis
… use of granulometric moments, arising from the morphological pattern spectrum, as texture descriptors to predict evolution time or class label of texture images which evolve over time or follow an intrinsic ordering of textures. A cubic polynomial regression is used to model each of several …

Morphological Segmentation During Silent Reading
… tested two hypotheses about the properties of morphological segmentation: (a) that it applies on phonemic representations, and (b) that it outputs affixal information that is taken up and used at representational levels higher than the lexical one. In two experiments, participants' …

Morphological Representations In Lexical Processing
… literature through an investigation of the morphological representations involved in auditory lexical processing. Previous work in theoretical morphology, spoken word recognition, and morphological processing are considered together in generating hypotheses. Chapter 2 provides theoretical …

Morphological awareness and spelling development
… this thesis is to analyse the relation between morphological awareness and morphologically based spellings, in Portuguese (European Variant). Two situations where the spelling is determined by morphology are examined: when the spelling flouts letter-sound correspondence rules (consistency in the …

Morphological alterations in frontotemporal dementia:
… explored the diagnostic potential of measuring morphological alterations in the white matter by diffusion tensor imaging (DTI)- MRI, compared with the more commonly used assessment of grey matter thickness and volume. DTI-MRI was better at separating FTD cases from controls than grey matter …

Morphological Changes in Compressible Foams
We introduce a model free energy, assuming the bubbles in the foam to come in just two sizes and calculate its global minimum for different values of the parameters. We then consider the transition in more detail and show how some subtle factors of the foam's structure and the parameters of the …

Unsupervised learning of morphological forests
This thesis focuses on unsupervised modeling of morphological families, collectively comprising a forest over the language vocabulary. This formulation enables us to capture edge-wise properties reflecting single-step morphological derivations, along with global distributional properties of the …

A Morphological Study of French Neologisms
… existing words. Studying these neologisms from a morphological approach can allow for a deeper understanding of where French is coming from, as well as where it is headed. This study focuses specifically on acronyms, <em>sigles</em>, and terms from the scientific, technological and socio-political …

Image watermarking, steganography, and morphological processing
… Image watermarking, steganogrphic system, morphological processing and shortest path planning are important subjects among them. In this dissertation, the fundamental techniques are reviewed first followed by the presentation of novel algorithms and theorems for these three subjects. The …

Cell polarity under extreme morphological conditions
… that polarity occurs in include a wide array of morphological properties such as size, shape, and growth. An important, conserved system of cell polarity depends on the intracellular localisation of proteins that act as diffusive molecular switches. Since the localisation of these proteins …

Molecular and Morphological Investigation of Astilbe
… within species, and the lack of adequate morphological characters to delineate taxa. To date, an inclusive investigation of the genus has not been conducted. This study was undertaken to (a) develop a well-resolved phylogeny of the genus Astilbe using an expanded morphological data set and …
