Targeted energy transfer using nonlinear energy sinks for the attenuation of transient loads on building structures
… buildings structures subjected to extreme transient loads. NESs are a type of passive attachment that differentiate themselves from tradition linear attachments through the exploitation of essentially nonlinear stiffness elements. The essentially nonlinear restoring force provided by these …

Study of a Modified Friction Device for the control of civil structures
In structural engineering, vibrations created by transient loads input energy to the structure. Control devices can be used to dissipate this energy in a civil structure. In this research, a new semi-active dissipation device is studied: the Modified Friction Device (MFD). The MFD is a control …

Free Vibration of Bi-directional Functionally Graded Material Circular Beams using Shear Deformation Theory employing Logarithmic Function of Radius
… plays a critical role in their design to avoid transient loads with dominant frequencies close to their natural frequencies. One way to increase their areas of applications and possibly make them lighter without sacrificing strength is to make them of Functionally Graded Materials (FGMs) that …

Predicting lubrication performance between the slipper and swashplate in axial piston hydraulic machines
… interfaces are subject to significant normal loads which must be supported while simultaneously preventing component wear to ensure long lasting operation. Proper lubrication design is essential to separate the solid bodies from each other, but the complexity of the physics involved makes this …

Analysis on Supercapacitor Assisted Low Dropout (SCALDO) Regulators
… efficiency, effective PCB footprint, noise and transient performance to suit different electronic circuit blocks. Switching regulators have relatively high end-to-end efficiency, in the range of 70 to 93%, but can have issues with output noise and EMI/RFI emissions. Switched capacitor converters …

Experimentelle Untersuchungen zur Verformungsakkumulation und Tragfähigkeitsreduktion von zyklisch belasteten Pfählen
… wind turbines are exposed to cyclic and dynamic loads. In this respect, different types of driven pile foundations, either the monopile or the multi-pile foundation, are frequently envisaged as foundation systems. Depending on the chosen variant the piles transfer the loading in different ways …

Thermodynamic modeling and microcalorimetry of nanostructured materials for capacitive thermal management of electronics
Transient power dissipation profiles in handheld electronic devices alternate between high and low power states depending on usage. Capacitive thermal management based on phase change materials potentially offers a fan-less thermal management for such transient profiles. However, such capacitive …
