Low frequency damping of metal panels in ambient Air [PDF]
Mathematical models of structural dynamics are widely used and applied in many branches of science and engineering and it has been argued that many of the shortfalls with these models are due to the fact that the physics of joint dynamics are not ...

ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

On the ambiguity of mechanical power
Introduction. Mechanical vibrations are widespread in the production processes. The drives of machines and mechanisms are mainly electromechanical, so mechanical reactive power is transformed into electrical reactive power of the network, impairing the ...

This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Nouvelle approche pour l’optimisation de systèmes mécaniques en vue de la récupération d'énergie vibratoire [PDF]
La récupération d’énergie à partir des vibrations mécaniques est une préoccupation importante à l’heure actuelle car elle permet de rendre autonome les systèmes de surveillance vibratoire ou de contrôle de vibration (semi-actif).
