Natural graphite sheet (NGS) is a candidate material for lightweight, high-performance heat sinks. We show that the low through-plane thermal conductivity can be mitigated by using heat pipes. In the measured configuration, the thermal resistance of

Detections of material regions on CT-scans of solids are commonly treated manually by an expert. Although such manual detections have many advantages, some amount of human error is also incorporated. Moreover, expert opinions may vary significantly.

The dimensions of a bearing structure tend to be designed as slender as possible to ensure aesthetics and to save material, which makes the structure more susceptible to damage caused by shear forces. When the structure is subjected to an earthquake,
