Determination of tooth cogging force in a hard-disk brushless DC motor

Yves Perriard, Marcel Jufer, Miroslav Markovic

The paper proposes a new method to determine the tooth cogging force in a brushless DC (BLDC) motor which is used in a hard-disk application. This force might be a source of tooth vibrations and motor noise. In the new method, the permanent-magnet (PM) pol ...

Weak force stalls protrusion at the leading edge of the lamellipodium

Jean-Jacques Meister, Sophie Bohnet, Alex Mogilner

Protrusion, the first step of cell migration, is driven by actin polymerization coupled to adhesion at the cell's leading edge. Polymerization and adhesive forces have been estimated, but the net protrusion force has not been measured accurately. We arrest ...

A Discrete choice framework for acceleration and direction change behaviors in walking pedestrians

Michel Bierlaire, Gianluca Antonini

The walking process is interpreted as a sequence of decisions about where to put the next step. A dynamic and individual-based spatial discretization is used to represent the physical space. A behavioral framework for pedestrian dynamics based on discrete ...

Gait-dependent integration of neck muscle afferent input

Grégoire Courtine

We investigated the integration of neck muscle afferents during walking and running. Subjects walked or ran straight ahead, with or without an additional mass (20% of body weight). They performed all trials without vibration and with continuous vibration ( ...

A new approach to define optimal acceleration shape based on an electrical model

Yves Perriard, Cédric Paroz

In modern robots and industrial machine tools, acceleration times begin to prevail over cruising times. This paper demonstrates the important relations between acceleration shape and the various characteristics of a drive system. These characteristics are ...

Polarity controls forces governing asymmetric spindle positioning in the Caenorhabditis elegans embryo

Pierre Gönczy

Cell divisions that create daughter cells of different sizes are crucial for the generation of cell diversity during animal development. In such asymmetric divisions, the mitotic spindle must be asymmetrically positioned at the end of anaphase. The mechani ...

Femtosecond dynamics of electronic 'bubbles' in solid argon: viewing the inertial response and the bath coherences

Majed Chergui, Franco Vigliotti, Marcia Portella Oberli

The dynamics of non-polar electronic solvation has been studied on a model system consisting of NO-doped solid Ar. Excitation of the lowest Rydberg state A(3ss) of NO leads to formation of an electronic 'bubble', which has been studied by femtosecond pump- ...

State-to-state studies of intramolecular energy transfer in highly excited HOOH(D): Dependencies on vibrational and rotational excitation

Thomas Rizzo

We use infrared-optical double resonance excitation, together with laser induced fluorescence (LIF) product detection, to measure rotationally resolved vibrational overtone spectra of hydrogen peroxide at energies up to 4500 cm(-1) above the O-O dissociati ...

Thermally actuated microprojector for optical display applications

Philippe Renaud, Sandra Schweizer, Gerhard Lammel

A dual axis, raster-scanning laser display based on a monolithic micromachined scanning mirror is presented. The scanner consists of a micromirror located at the end of a thermally actuated bimorph beam. The novelty of the device is that an "L"-shape canti ...

Improved design of a silicon micromachined gyroscope with piezoresistive detection and electromagnetic excitation

Nico de Rooij

In this paper, an improved design of a silicon micromachined gyroscope (angular rate sensor) is presented. It is based on the tuning fork principle and realized by combining two proof masses. The gyroscope is driven by electromagnetic forces and detects th ...
