DigitalSeed: An interactive toy for children’s explorations of plant growth and life cycles
Preschool children, aged 4 and 5 years, report different understandings of the phenomenon of plant reproduction. We use their ideas as a starting point in designing an electronic device that illustrates phases of plant growth in response to children's augm ...
2002Environmental Geomechanics
Lyesse Laloui, Laurent Vulliet
« Environmental Geomechanics » is a relatively new discipline at the interface between built and natural environment. It is devoted to the understanding of the mechanical behavior of geomaterials (mainly soil and rock but also concrete and others) under va ...
PPUR2002Efficient Search in Unbalanced, Randomized Peer-To-Peer Search Trees
Scalable mechanisms to support efficient key-based search in distributed systems are an important part of the infrastructure of peer-to-peer systems and global information systems. They received substantial attention both in information and communication s ...
2002An insensitivity property of Lundberg's estimate for delayed claims
This short note shows that the Lundberg's exponential upperbound in the ruin problem of non-life insurance with compound Poisson claims is also valid for the Poisson shot noise delayed claims model, and that the optimal exponent depends only on the distrib ...
2000Characterization of an encapsulation device for the production of monodisperse alginate beads for cell immobilization
Urs von Stockar, Ian William Marison, David Serp
An encapsulation device, designed on the basis of the laminar jet break-up technique, is characterized for cell immobilization with different types of alginate. The principle of operation of the completely sterilizable encapsulator, together with technique ...
2000On an exact analytical solution of the Boussinesq equation
A useful exact analytical solution of the Boussinesq equation is discussed and is the most general solution presently available, and in particular yields a solution for a finite aquifer. It provides insight into the physical processes arising during the ex ...
2000Horizontal distribution patterns of testate amoebae (Protozoa) in a Sphagnum magellanicum carpet
Alexandre Buttler, Edward Mitchell, Jean-Michel Gobat, Daniel Borcard
The distribution of soil microorganisms is generally believed to be patchy and to reflect habitat heterogeneity. Despite this general rule, the amount of existing data oil species distribution patterns is scarce. Testate amoebae (Protozoa; Rhizopoda) are a ...
2000Concentration of simple aldehydes by sulfite-containing double-layer hydroxide minerals: implications for biopoesis
Environmental conditions play an important role in conceptual studies of prebiotically relevant chem. reactions that could have led to functional biomols. The necessary source compds. are likely to have been present in dil. soln., raising the question of h ...
2000Mapping the B1 Field Distribution with Nonideal Gradients in a High-Resolution NMR Spectrometer
To understand the behavior of many NMR expts., it is important to det. the spatial distribution of the B1 field. In this paper, we show how this distribution can be mapped independently of spin d., coil responsiveness, and nonlinearities of the B0 field gr ...
1999Simulation of Airlift Pumps for Deep Water Wells
A mathematical model for the simulation of water airlift pumps is developed, based on the "interspersed continua" approximation for two-phase flow systems, together with an algorithm that selects the appropriate friction correlation for specific flow regim ...
