Mass preserving finite element implementations of the level set method

Nicola Parolini, Daniele Antonio Di Pietro

In the last two decades, the level set method has been extensively used for the numerical solution of interface problems in different domains. The basic idea is to embed the interface as the level set of a regular function. In this paper we focus on the nu ...

Creating Virtual Prototypes of Complex Micro-Electro-Mechanical Transducers Using Reduced-Order Modelling Methods and VHDL-AMS

Torsten Mähne

In this paper the creation of "virtual prototypes" of complex micro-electro-mechanical transducers is presented. Creating these behavioural models can be partially automatised using a reduced-order modelling (ROM) method. It uses modal decomposition to rep ...

Measurement of γγ → pp̄ production at Belle

Aurelio Bay, Stewart Cole, Tagir Aushev, Sun Hee Kim, Sanjeev Kumar

A high precision study of the process γγ→pp̄ has been performed using a data sample of 89 fb-1 collected with the Belle detector at the KEKB e+e- collider. The cross section of pp̄ production has been measured at two-photon center-of-mass (c.m.) energies b ...

Characterization of supersonic low pressure plasma jets

Malko Gindrat

Low Pressure Plasma Spraying (LPPS) processes use a DC plasma jet expanding at low pressure for fast deposition of dense coatings in a controlled atmosphere. The LPPS technology is widely used industrially in particular in the aeronautics and medical indus ...

Measurement of K+K- production in two-photon collisions in the resonant-mass region

Olivier Schneider, Aurelio Bay, Chao Wang, Tagir Aushev, Sun Hee Kim, Yuan Yuan, Ji Hyun Kim, Jing Li

K+K- production in two-photon collisions has been studied using a large data sample of 67 fb-1 accumulated with the Belle detector at the KEKB asymmetric e+e- collider. We have measured the cross section for the process γγ → K +K- for center-of-mass energi ...

Three axis active magnetic levitation for inertial sensing systems

Roland Moser, François Barrot, Alexis Boletis

The invention relates to an inertial sensor based on the magnetic levitation of an inertial mass comprising an active magnetic bearing unit arranged in such a way as to levitate the inertial mass and characterized by the fact that it furthermore comprises ...

Observation of B+ ∧ ∧K+

Mingkui Wang, Tagir Aushev, Sun Hee Kim, Ji Hyun Kim, Jing Li

The observation of the hyperonic B+ → λλ̄K+ decay was presented. It was found that the rate of a charmless B decay was comparable to that of other charmless three-body baryonic modes. It was also found that the invariant mass of the λλ̄ system had a promin ...

Calculation of variable-topology free surface flows using CONNFFESSIT

Marco Picasso

The capability of calculation of non-Newtonian flows: finite elements and stochastic simulation technique (CONNFFESSIT) to compute transient free surface flows is extended to deal with transient viscoelastic flows for domains in which the topology (connect ...

PARTICLE FIELDS OF ICE SLURRIES WITH STRATIFICATIONS AND MELTING

Didier Albert Simon Vuarnoz

Results on isothermal stratification of ice particles in ice slurry storage tanks are presented. Furthermore - in an extension - the melting of ice particles by heat fluxes across the boundaries of storage vessels is also taken into consideration. A conser ...
