Model-based target sonification on mobile devices [PDF]

, 2004
We investigate the use of audio and haptic feedback to augment the display of a mobile device controlled by tilt input. We provide an example of this based on Doppler effects, which highlight the user's approach to a target, or a target's movement from ...

Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

Advanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Development of CMG Active Vibration Control Device for Gondola

JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1994
For reduction of the low-cycle vibration of vehicles such as gondolas which are suspended flexibly, the authors studied the utilization of the control moment gyro (CMG) as an active vibration control device. The CMG is a moment generator using the gyroscopic moment effect and it is applied to attitude control of spacecraft. Particularly in the very-low-

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

A novel active vibration suppression device based on momentum wheel and pendulum-tuned mass damper

Journal of Low Frequency Noise, Vibration and Active Control
During the mass transfer process of micro-LEDs, equipment may be affected by low-frequency vibrations, leading to issues such as poor chip alignment accuracy and reduced yield rates.

Optimal design of inerter devices combined with TMDs for vibration control of buildings exposed to stochastic seismic excitation [PDF]

, 2013
This paper proposes a novel configuration for the passive vibration control of seismically excited buildings combining the "inerter", a recently developed Two-Terminal Flywheel (TTF) device, with the classical Tuned Mass Damper (TMD).

Characterising and Testing Deep UV LEDs for Use in Space Applications

, 2015
Deep ultraviolet (DUV) light sources are used to neutralise isolated test masses in highly sensitive space-based gravitational experiments. An example is the LISA Pathfinder charge management system, which uses low-pressure mercury lamps.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
