After validation of the wave climate, the results were integrated with information from the submarine relief, and plant morphology of beaches and barrier islands systems. On the second phase, the objective was to analyze the evolution of the wave and its interaction with the shallow seabed, from three transverse profiles orientation from N to S, distributed according to the parallel longitudinal, X = 774000-W, 783000-W e 800000-W. Subsequently, it was were extracted the values of directional waves and winds through all the months between november 2010 to november 2012, to analyze the impact of these forces on the movement area, and then understand the behavior of the morphological variations according to temporal year variability. Based on the results of modeling and its integration with correlated data, and planimetric variations of Soledade and Minhoto beach systems and Ponta do Tubar?o and Barra do Fernandes barrier islands systems, it was obtained the following conclusions: SWAN could reproduce and determine the wave climate on the north continental shelf at RN, the results show a similar trend for the measurements of temporal variations of significant height (HS, m) and the mean wave period (Tmed, s); however, the results of parametric statistics were low for the estimates of the maximum values in most of the analyzed periods compared data of PT 1 and PT 2 (measurement points), with alternation of significant wave heights, at times overrated with occasional overlap of swell episodes. By analyzing the spatial distribution of the wave climate and its interaction with the underwater compartmentalization, it was concluded that there is interaction of wave propagation with the seafloor, showing change in significant heights whenever it interacts with the seafloor features (beachrocks, symmetric and asymmetric longitudinal dunes, paleochannel, among others) in the regions of outer, middle and inner shelf. And finally, it is concluded that the study of the stability areas allows identifications of the most unstable regions, confirming that the greatest range of variation indicates greater instability and consequent sensitivity to hydrodynamic processes operating in the coastal region, with positive or negative variation, especially at Ponta do Tubar?o and Barra do Fernandes barrier islands systems, where they are more susceptible to waves impacts, as evidenced in retreat of the shoreline / Esta tese apresenta os resultados da aplica??o do modelo num?rico SWAN Simulating WAves Nearshore, de terceira gera??o, que a simula propaga??o e dissipa??o da energia das ondas do mar, na plataforma continental setentrional do Rio Grande do Norte, com vista a determinar o clima de ondas, calibrar e validar o modelo e aferir suas potencialidades e limita??es para a regi?o de interesse. Ap?s a valida??o do clima de ondas os resultados foram integrados com as informa??es do relevo submarino e morfologia em planta dos sistemas de praias e ilhas barreiras. Nesta segunda fase, o objetivo foi analisar a evolu??o da onda e sua intera??o com o fundo marinho raso a partir de tr?s perfis transversais de orienta??o de N para S, distribu?dos conforme as paralelas longitudinais, X = 774000-W, 783000-W e 800000-W. Posteriormente, extra?ram-se os valores direcionais de ondas e ventos ao longo de todos os meses compreendidos entre novembro de 2010 a novembro de 2012, para analisar a incid?ncia destas for?antes sobre a movimenta??o de ?rea para entender o comportamento das varia??es morfol?gicas de acordo com a variabilidade temporal anual. Com base nos resultados da modelagem e da sua integra??o com os dados correlacionados e das varia??es planim?tricas dos sistemas praiais de Soledade e Minhoto e das ilhas barreiras Ponta do Tubar?o e Barra do Fernandes, obteve-se as seguintes conclus?es: o SWAN conseguiu reproduzir e determinar o clima de ondas para o litoral setentrional do RN, os resultados mostram tend?ncia semelhante com as medidas nas varia??es temporais de altura significativa (HS, m) e per?odo m?dio de onda (Tmed, s), entretanto, os resultados param?tricos das estat?sticas mostraram-se baixos para as estimativas dos valores m?ximos, na maioria dos per?odos analisados em compara??o os dados do PT 01 e PT 02 (pontos de medi??o), com altern?ncia das alturas significativas de ondas, em alguns momentos sobrestimado com a sobreposi??o ocasional de epis?dios de ondula??o. Ao analisar a distribui??o espacial do clima de ondas e sua intera??o com a compartimenta??o submarina, concluiu-se que h? intera??o da propaga??o da onda com o fundo, evidenciando altera??o nas alturas significativas sempre quando esta interage com as fei??es de fundo (rochas praiais, dunas longitudinais sim?tricas e assim?tricas, paleocanal, dentre outros) existentes nas regi?es das zonas da plataforma externa, m?dia e interna. E finalmente notou-se que especialmente as ilhas de Ponta do Tubar?o e Barra do Fernandes, est?o mais sujeitas a incid?ncia das ondas, causando o recuo da linha de costa; o estudo das ?reas de estabilidade permitiu identificar as regi?es mais inst?veis, corroborando com o senso de que a maior amplitude de varia??o indica maior instabilidade e consequente sensibilidade aos processos hidrodin?micos atuantes na regi?o costeira, seja esta varia??o positiva ou negativa

Στόχος της παρούσας μεταπτυχιακής εργασίας είναι η περιγραφή και η σύγκριση της μορφολογικής διαδικασίας της σύνθεσης στις νεοελληνικές διαλέκτους όπως προκύπτει από την ανάλυση 2500 συνθέτων από τρεις διαφορετικές διαλέκτους, την Κρητική, την Ποντιακή και την Επτανησιακή. Στο πρώτο κεφάλαιο γίνεται μία σύντομη επισκόπηση των ορισμών που έχουν προταθεί για τη σύνθεση αναδεικνύοντας τους λόγους που καθιστούν δύσκολη τη διατύπωση ενός ορισμού που να ανταποκρίνεται διαγλωσσικά. Επίσης, παρουσιάζονται οι βασικές ιδιότητες που διέπουν τη σύνθεση της ελληνικής γλώσσας και τα βασικά χαρακτηριστικά που διαχωρίζουν τη σύνθεση από τις υπόλοιπες μορφολογικές διαδικασίες (π.χ. παραγωγή) αλλά και από τη σύνταξη κυρίως με βάση τις μελέτες της Ράλλη (2007) και Ralli (2013). Στο δεύτερο κεφάλαιο εξετάζονται τα κατηγοριακά σχήματα πάνω στα οποία δομούνται τα σύνθετα στις τρεις υπό εξέταση διαλέκτους και στη συνέχεια συγκρίνεται η παραγωγικότητά τους. Στο τρίτο κεφάλαιο τα σύνθετα ταξινομούνται με βάση τις γραμματικές σχέσεις των συστατικών τους. Στο τέταρτο κεφάλαιο μελετάται η σχέση μορφής και σημασίας και προτείνεται η διαίρεση των συνθέτων σε τρεις μεγάλες τάξεις: α) διαφανή, β) ημιδιαφανή και γ) αδιαφανή σύνθετα. Στο πέμπτο και έκτο κεφάλαιο εξετάζεται η σχέση της σύνθεσης με την παραγωγή και την κλίση αντίστοιχα μέσα από τα δεδομένα των τριών διαλέκτων. Τέλος, στο έβδομο κεφάλαιο μελετάται η συχνότητα εμφάνισης θεμάτων ξενικής προέλευσης ως συστατικά των συνθέτων στις τρεις αυτές διαλέκτους. / The aim of this master thesis is to describe and compare the morphological process of compounding in Modern Greek dialects based on the analysis of 2500 compounds. Data comes from three dialects, namely, Cretan, Pontic, and Heptanesian. The first chapter briefly presents some of the definitions which have been proposed for compounding highlighting the reasons that make the formulation of a definition that applies cross-linguistically a difficult task. It also presents the basic properties that govern the formation of Greek compounds and the main characteristics that distinguish compounding from the other morphological processes (e.g. derivation) and from syntactic operations based on the studies of Ralli (2007) and Ralli (2013). The second chapter presents the main patterns which are involved in the compounding process and compares their productivity cross-dialectally. In chapter three compounds are classified according to the grammatical relations between their components. The fourth chapter examines the relation between form and meaning and it suggests a division of compounds in three large classes: a) transparent, b) semi-transparent and c)opaque. The next two chapters examine the relation between compounding andderivation and inflection respectively. Finally, chapter seven examines whether stems of foreign origin appear frequently as components of compounds in these dialects.
