We present a new method for estimating heart motion from two-dimensional echocardiographic sequences by exploiting two ultrasound modalities: B-mode and tissue Doppler. The algorithmestimates a two-dimensional velocity field locally by using a spatial affi ...
A review. Ab initio mol. dynamics (MD) allows realistic simulations to be performed without adjustable parameters. In recent years, the technique has been used on an increasing no. of applications to biochem. systems. Here we describe the principles on whi ...
The nucleation and growth of microcracks in elastic lamellar microstructures is studied numerically. The analyses are carried out within a framework where the continuum is characterized by two constitutive relations: one relating the stress and strain in t ...
Life cycle assessment (LCA) is a framework for comparing products according to their total estimated environmental impact, summed over all chemical emissions and activities associated with a product at all stages in its life cycle (from raw material acquis ...
A method is presented to predict fatigue life which explicitly accounts for specimen specific damage histories and the statistical distribution of quasi-static tensile strengths. First a 'critical element' is identified as that portion of the composite whi ...
We present an assessment of the performance of a new on-line bin packing algorithm, which can interpolate smoothly from the Next Fit to Best Fit algorithms, as well as encompassing a new class of heuristic which packs multiple blocks at once. The performan ...

We present a new type of microinstrument allowing manipulation and mechanical perturbation of individual cells under an optical microscope. These instruments, which we call microplates, are pulled from rectangular glass bars. They have flat tips, typically ...
We use photoluminescence and photoluminescence excitation experiments with and without magnetic field to study the electronic properties of InxGa1-xAs/GaAs quantum wells grown on vicinal (001) substrates. We analyze samples of a wide range of In contents ( ...
The LIDAR principle for air quality and meteorol. measurements is presented, followed by different examples of vertical O3 profiles and time series obtained with a new optical layout of the EPFL-LPAS DIAL system using dual telescope detection. These data w ...
1,4-Dienes, vinyl ethers, allyl ethers, allyl thio ethers, and propenethiolates were metalated by BuLi in the presence of an activator such as KOCMe3. Since the solvent, the counter-ion, or the temp. may be varied before subsequent treatment with an electr ...
