lderesi and Bakacak landslides in Asarsuyu Catchment for 42 years period by the digital aerial photogrammetric techniques while evaluating the possible use of archive aerial photography in such analysis. To achieve the purpose of the study an orthophoto map was generated by aerial photographs belonging to 1994 year. The orthophoto map was utilized as a base map for aerial photo interpretation of different sets of aerial photographs corresponding to 1952, 1972, 1984 and 1994 years. As a result of this, 4 landslide activity maps are obtained. In addition, the characteristics of these landslides are analyzed by utilizing digital elevation model (DEM) created from stereo photographs of 1994. As a result of the study, no considerable variation is detected in the position of main boundaries of Bü
lbü
lderesi and Bakacak landslides except some minor differences. However, within the landslides many topographical changes were observed between 1952 and 1994 period. Based on the profiles from toe to crest of the Bü
lbü
lderesi landslide, the approximate length was measured as 4773m whereas the approximate width was about 2614m. The areal extent was calculated as ~12km2 having an approximate slope gradient ranging between 10-15°
with local variations. On the other hand, the approximate length of Bakacak landslide was 4420m and the approximate width was 832m from toe to crest with an area of ~4km2 and with an approximate slope angle 9-14°

Full textEn esta tesis se formaliza la construcción de modelos multivista 2D a partir de datos 3D, a través de varias extensiones del conocido método Procrustes Analysis (PA). Las extensiones propuestas permiten modelar transformaciones rígidas y no rígidas eficientemente, y se han puesto a prueba en bases de datos de caras y cuerpos humanos. Las aplicaciones donde se perciben humanos permiten establecer restricciones físicas, tales como definir caras y esqueletos como conjuntos de puntos anatómicos. Sin embargo, la gran variación que sufren las expresiones faciales y las posturas humanas desde distintos puntos de vista convierten problemas como el seguimiento de caras o la estimación de la postura humana en retos extremadamente complejos. El planteamiento habitual para gestionar grandes variaciones de punto de vista consiste en entrenar los modelos con imágenes etiquetadas tomadas con distintas orientaciones. Sin embargo, este enfoque sufre importantes inconvenientes: (1) no queda claro cuántas imágenes adicionales con distintas orientaciones son necesarias con tal de construir modelos 2D no sesgados por ningún punto de vista; (2) extender el conjunto de datos de entrenamiento sin esta evaluación incrementaría innecesariamente el coste computacional en tiempo y en memoria; (3) obtener nuevas imágenes etiquetadas con distintas orientaciones puede tratarse de una tarea compleja debido al elevado coste del etiquetado manual; finalmente, (4) no cubrir uniformemente los distintos puntos de vista de una persona conduce a modelos sesgados. En esta tesis se proponen sucesivas extensiones de PA para hacer frente a estos problemas. Primero, proponemos Projected Procrustes Analysis (PPA) para formalizar la construcción de modelos rígidos multivista 2D a partir de conjuntos de datos 3D. PPA rota y proyecta cada objeto 3D y construye un modelo 2D a partir de este conjunto de datos enriquecido. También mostramos como rotaciones uniformemente distribuidas generan modelos 2D no sesgados, mientras rotaciones no uniformes conducen a modelos que representan algunos puntos de vista mejor que otros. Aunque PPA construye modelos multivista 2D, necesita un conjunto de entrenamiento enriquecido que incrementa los requisitos computacionales. Para solventar este problema de PA y PPA, proponemos Continuous Procrustes Analysis (CPA). CPA extiende PPA en un marco de análisis funcional y construye modelos rígidos multivista 2D de un modo eficiente, integrando todas las posibles rotaciones en un dominio dado. Mostramos como los modelos generados con CPA son inherentemente no sesgados debido a la formulación integral. Sin embargo, CPA no captura las deformaciones no rígidas de los datos. En consecuencia, proponemos Subspace Procrustes Analysis (SPA) con el objetivo de construir modelos deformables multivista 2D de un modo eficiente a partir de datos 3D. Añadiendo un subespacio a la formulación de PA, SPA es capaz de modelar deformaciones no rígidas, así como transformaciones 3D de los datos. Desarrollamos una formulación discreta (DSPA) y otra continua (CSPA), donde DSPA muestrea y CSPA integra el espacio de rotaciones 3D. Finalmente, ilustramos las ventajas de nuestros modelos deformables multivista 2D en la tarea de estimar la postura humana. Primero reformulamos el problema como una selección de características por subespacio coincidente y proponemos un método para resolver esta tarea eficientemente. Después, mostramos como nuestros modelos multivista 2D, combinados con la selección de características por subespacio coincidente, mejoran el estado del arte de estimación de la pose humana. Nuestro método es más preciso en la posición de las articulaciones y la longitud de las extremidades por el uso de modelos multivista 2D entrenados en bases de datos de captura de movimiento 3D. Nuestros modelos no están sesgados por punto de vista y pueden reconstruir deformaciones rígidas y no rígidas. Además, estos modelos son eficientes tanto en su construcción como en su uso

Full textPapper har länge använts som förpackningsmaterial men traditionella pappers- och kartongförpackningar är begränsade i form och design. Olika 3-D formnings processor har studerats för att möjliggöra mer avancerade pappersbaserade förpackningar. Effekterna av fukt och temperatur på pappers mekaniska egenskaper har också undersökts eftersom fukt och temperatur har stor betydelse för slutresultatet i 3-D formningsprocesser. I Artikel A har den kombinerade effekten av fukt och temperatur på de uniaxiella mekaniska egenskaperna av papper undersökts experimentellt. Dessa experiment visar hur fukt och temperatur påverkar både elastiska och plastiska egenskaper hos papper samt ligger till grund för modelleringen av inverkan av fukt och temperatur i Artikel C. I Artikel B har en explicit finita element modell för djupdragning av kartong utvecklas. En ortotropisk materialmodell baserad på en rektangulär flytyta har utvecklats och verifierats för kartong. Simuleringen följde trenderna i experimenten fram till den punkt där mikroskopiska rynkor bildas. Resultaten från analyserna med modellen ger kvantitativ förståelse för materialbrott i djupdragningsprocessen eftersom de flesta experimentella materialbrott inträffar innan mikroskopiska rynkor bildas. I Artikel C har ett explicit finita element modell av hydroformning av papper baserad på materialmodellen från Paper B utvecklats och verifierats mot experimentell hydroformning av papper. En parameterstudie med finitaelement-modellen producerade kvantitativ förståelse för hydroformningsprocessen för papper. Dessutom identifieras torkning som ett viktigt fenomen för att fastställa graden av formbarheten för pappersmaterial.

Ao longo desta dissertação desenvolvemos o formalismo de Hamilton-Jacobi para teorias de campo para o caso de sistemas singulares e não-singulares. Em seguida, aplicamos tal formalismo nos modelos BF em D=1+1, D=2+1 e D=3+1 dimensões a fim de caracterizar os seus espaços de fase. Mostramos que a partir desse formalismo é possível obter as simetrias locais desses modelos assim como os seus respectivos geradores.
Throughout this dissertation we develop the Hamilton-Jacobi formalism for field theories in the case of singular and non-singular systems. Next, apply such formalism on the BF models in D=1+1, D=2+1 e D=3+1 dimensions in order to characterize their phase spaces. We show from this formalism, that is possible to find the local symmetries of those models as well as their respective generators.

Full textayyolu metro line (Ankara, Turkey), challenging ground conditions involving highly heterogeneous and locally water saturated foundation soils have been encountered. Possibility of damage at the surface and/or on the underground structures can be estimated using finite difference method (FDM) of analysis. In this study, two geophysical methods namely Electrical Resistivity Imaging (ERI) and Ground Penetrating Radar (GPR) were utilized to distinguish soil types at the study area. By correlating these geophysical survey results with the boring v logs, 3-Dimensional soil profile was revealed at the study area to build up a basis for numerical models. 3-Dimensional (3D) FDM analyses were conducted to assess tunneling induced deformations, along with movements around shallow soft ground main tunnels and connection tunnels. During sequential excavations, temporary and permanent shotcrete lining was also simulated. The soil behavior is assumed to be governed by an elastic-perfectly plastic constitutive relation based on the Mohr&ndash
Coulomb criterion. The computed deformations around these openings have been compared with the in-situ measurements. The results of the study revealed that the 3-D elasto-plastic analyses yield comparably good correlation with the in-situ measurements. Also, in this study, the effects of main tunnels excavations on each other and the effects of connection tunnels excavations on main tunnels were identified in terms of ground deformations. In order to simulate induced surface settlement due to groundwater withdrawal at the site 3-D fully coupled (fluidmechanical) numerical models were run using different time durations. The model studies revealed that deformations monitored at the ground surface are directly related with the tunnel construction practice. Pumping groundwater has very little or no effect on the measured deformations.
