A simple method to predict elastic settlements in foundations resting on two soils of differing deformability

This paper shows the analysis results obtained from more than 200 finite element method (FEM) models used to calculate the settlement of a foundation resting on two soils of differing deformability. The analysis considers such different parameters as the foundation geometry, the percentage of each soil in contact with the foundation base and the ratio of the soils’ elastic moduli. From the described analysis, it is concluded that the maximum settlement of the foundation, calculated by assuming that the foundation is completely resting on the most deformable soil, can be correlated with the settlement calculated by FEM models through a correction coefficient named “settlement reduction factor” (α). As a consequence, a novel expression is proposed for calculating the real settlement of a foundation resting on two soils of different deformability with maximum errors lower than 1.57%, as demonstrated by the statistical analysis carried out. A guide for the application of the proposed simple method is also explained in the paper. Finally, the proposed methodology has been validated using settlement data from an instrumented foundation, indicating that this is a simple, reliable and quick method which allows the computation of the maximum elastic settlement of a raft foundation, evaluates its suitability and optimises its selection process.

The Summary of a Course of Experimental Philosophical Lectures, 1746-1747

Leather hardcover notebook containing a handwritten copy of John Winthrop's course of experimental and philosophical lectures presented between March 10, 1746 and June 16, 1746. The first one-hundred pages of the volume are divided into twenty chapters which were presented in thirty-three lectures. The chapters contain text and diagrams on mechanical powers, the lever, the pulley, the axis in peritrochio, the inclined plane, the wedge, the screw, compound engines, the laws of motion, gravity, attraction of cohesion, the power of repulsion, magnetism, fluids, electricity, opticks, and astronomy. There is a five-page addenda to the course summary added in 1747, and a sixty-page text titled "The Method of Astronomical calculations" containing thirteen problems related to calculating distances with a list of astronomical characters, and followed with charts related to the eclipse of Jupiter's satellites.

From Dr. Watt's Philosophical Essays, undated

Three leaves containing handwritten extracts and notes on sections II and III of Isaac Watt's essay, "A fair inquiry and debate concerning space, whether it be something or nothing, God or Creature." A section of notes for a third essay is incomplete.

A importância da liberdade na correspomdência entre Gottfried Leibniz e Samuel Clarke, 1717/1716: análise temática da totalidade da polémica

A presente dissertação tem como objetivo analisar tematicamente a polémica de 1715/16 entre Leibniz e Clarke, não apenas, como é usual, no âmbito das conceções do espaço e do tempo, mas no conjunto dos seus temas metafísicos, teológicos, gnosiológicos e físicos. Na estruturação da dissertação, adquiriu um papel central o confronto dos autores em torno da noção de liberdade, cuja importância é evidente na utilização do princípio da razão suficiente e seus corolários, na distinção entre verdades de razão e verdades de facto, entre os diversos tipos de necessidade, nas conceções alternativas de espaço e de tempo, na alternativa entre átomos e mónadas, na questão dos limites do universo, na relação entre a alma e o corpo, nas teses relativas à providência divina, na forma como se concebe a relação de Deus com a sua máquina, na noção de milagre e nas próprias noções de força e de movimento, pelo menos no que respeita à sua relação com Deus, isto sem desprezar a abordagem direta da própria noção de liberdade. Com este enquadramento, pretende-se mostrar, através de um eloquente exemplo histórico, que as teorias científicas naturais se podem alicerçar em teorias metafísicas e que esses alicerces não têm que se esgotar, mesmo no seio da metafísica, nas questões estritamente cosmológicas, isto para lá de poderem existir influências nunca menosprezáveis de domínios não filosóficos, como é o caso da teologia dogmática. Apesar disto ser evidente na abordagem dos textos, existe uma sistemática menorização contemporânea desta determinação, como se fosse uma idiossincrasia da época ou uma deferência que a ciência tinha de ter numa época ainda obscurecida pela autoridade das igrejas e pela especulação filosófica. Esta abordagem pretende compreender todos os aspetos do pensamento expresso pelos autores na polémica, na sua integralidade, sem reservas de qualquer tipo.

Does the European Union create the foundations of an information society for all? Bruges European Economic Policy (BEEP) Briefing 11/2005

In order to increase the use of information and communication technologies (ICT) in the European Union Member States, the European Commission, on the initiative of Commissioner E. Liikannen, launched in December 1999 a bold programme called “eEurope”. Soon after its creation, the eEurope programme was integrated into the so- called Lisbon agenda for Europe to become the “most advanced knowledge based economy” in the world. We try to assess if the programme is successful in achieving its stated objective of promoting a knowledge based economy through the development of an “information society for all”. First, we conclude that eEurope, due to its origins and its procedures, has intrinsic limits both as regards its scope and effectiveness. Second, we show how Member States have adopted different trajectories towards the “knowledge based society”. To identify these heterogeneous paths of growth, we have selected a set of variables that, combined together, represent the institutional arrangements specific to a country or a group of countries. We found sharp differences between two advanced models that we label, respectively, as Scandinavian and Anglo-Saxon. Without asserting the superiority of a model, we propose policy orientations to help Europe overcome those gaps hindering the move towards knowledge economies where information society technologies are widely diffused.
