Elastomeric elements are currently used as external dampers in many applications to increase the stability of dynamical systems, e.g., rotor-bearings systems. However, the dynamic design of systems embedded with elastomeric dampers is a hard task, since the properties of this kind of ... En savoir plus

Nondestructive inspection (NDI) of damages (e.g., imperfect or degraded bonding lines) or the remaining strength of adhesively bonded lap joints is critical for the operational safety of aircrafts and vehicles. It remains a challenge to use the conventional NDI to quantitatively infer ... En savoir plus

We present an easy-to-use toolbox for the automated generation of reduced-order mixed-level models for the evaluation of squeeze-film damping in microelectromechanical systems. The toolbox is programmed in JAVA and heavily exploits the functionality provided by the COMSOL API. The ... En savoir plus

Figure 1 shows a simplified scheme of a typical industrial steam methane reforming (SMR) reactor, which is a top-fired, packed-bed multi-tubular chemical reactor, consisting of a series of catalytic tubes arranged within a furnace. The tubes contain two adjacent catalytic sections filled ... En savoir plus

Radiation therapy is a key cancer treatment, used in over 50% of cases, either as a standalone or in combination with surgery and chemotherapy. It involves delivering ionizing radiation to damage cancer cell DNA, preventing their proliferation. Conventional radiotherapy mainly employs X ... En savoir plus

Perovskite solar cells (PSCs) are a promising photovoltaic technology but their performance remains limited by incomplete absorption of incident photons, primarily due to reflection at the transparent front electrode [1]. To address this issue, interface engineering with graphene-based ... En savoir plus

MEMS microphones have been widely adopted in a variety of consumer electronic systems. To ensure clear speech transmission and avoid degradation of important signals, careful tuning of microphone port geometry is essential to mitigate wind-induced airborne noise. This additional noise ... En savoir plus

Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... En savoir plus

RAKON is a worldwide expert in high performance crystal oscillator. The company decided to expand its product range to larger space equipment, the Master Reference Oscillator (MRO). This product is composed of stacked mechanical modules, joined together by structural screwed assemblies. ... En savoir plus
