Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... En savoir plus

Acoustic Resonance (Acu-Res®) Technology [1] is at the core of FT wind sensors, operating by measuring phase shifts between a pair of transducers caused by fluid flow within an acoustic resonator. Three piezoelectric transducers are placed in a triangular formation on the top reflector ... En savoir plus

INTRODUCTION: The paper illustrates the use of COMSOL for obtaining the solution Ψ(x,y,t) as a solution to the time dependent nonlinear Schrödinger equation (NLSE). COMSOL previously was used to solve the time dependent NLSE in Ref.[1] as applied to quantum mechanics, however this is the ... En savoir plus

Electrochemical Machining (ECM) is a non-conventional machining technology which allows for surface structuring and shaping of metallic workpieces with high accuracy and surface quality. The machining principle of ECM is electrolysis. Hence, the mechanical properties of the workpiece ... En savoir plus

This study focuses on comparing various fluid dynamic models for analyzing airflows within the cooking chamber of an oven. The comparison is conducted in three steps. First, a study of the fan directly connected to a test tube in suction mode, discharging radially into free space. ... En savoir plus

Very recently, the synthesis and experimental study of a new class of highly charged polymer particles has been described, which spontaneously charge in non-aqueous low-polarity solvents [1,2]. These suspensions are an example of what is known as salt-free systems. The study of ... En savoir plus

Introduction Throughout the field of micro- and nanoscale electrokinetics, floating bipolar electrodes (BPEs) have proven to be useful in manipulating charged ionic species and biomolecules for electroanalytical studies. The growing use of integrated electronics in working towards fully ... En savoir plus

Atherosclerosis is a disease that narrows, thickens, hardens and restructures a blood vessel due to substantial plaque deposit. In the Carotid Artery, the decision to treat using endarterectomy and stenting is determined by the velocity as measured by Doppler flow in the common Carotid ... En savoir plus

In a diagnostic system small magnetic beads of about 1µm diameter will be moved along a path in a viscose medium due to magnetic field actuators. Specific ligands on the beads will bound to specific samples. If bound, the diameter and mass of the beads rise and the bead movement is ... En savoir plus

Recognized for its potential as a sustainable food source, seaweed farming has become pivotal in tackling future food security concerns, necessitating innovative solutions to achieve optimal, high-yield, and commercially viable production [1]. This work addresses gaps in aquaculture ... En savoir plus
