A major problem in robotics vision is the segmentation of images of natural scenes in order to understand their content. This thesis presents a new solution to the image segmentation problem that is based on the design of a rule-based…

A new vapor-liquid equilibrium apparatus was constructed to measure temperature, pressure, and phase compositions up to 8 MPa. Systems of CO(,2) with 2-methyl-1-pentene, 1-hexene, 1-heptene and m-xylene were studied at 303.15 K, 323.15 K, and 343.15 K., A general method…

The level structures of ('94)Ru, ('90)Mo, ('88)Zr, ('89)Mo and ('89)Nb have been studied via the decay of two isomers of ('94)Rh, two of ('90)Tc, two of ('88)Nb, one of ('89)Tc and one of ('89)Mo, respectively. These nuclides were produced via…

The development of precise data for the effect of chemistry and processing variables on the fracture toughness of low to medium carbon cast steels, is paramount to an increased understanding of the fracture behaviour of these important engineering materials. This…

Research on self-regulated learning (SRL) in hypermedia-learning environments is a growing area of interest. One major issue is the role of prior knowledge, which can influence how students interact with hypermedia-learning systems in terms of their use of SRL strategies.…

Knowledge of the distribution of soil organic matter (SOM) fractions is important in managing soils toward a sustainable agricultural system ina tropical environment, However, data on Histosols in limited. This study developed 19 regions of Brazil. Soil organic matter was…

Los estudios de esta tesis doctoral muestran la relación estrecha que existe en la Fenomenología del Espíritu entre el concepto hegeliano de experiencia, su concepción del absoluto y el impacto que tiene en ambos el desafío del escepticismo. La tesis…
