Abstract: The archetypical topology optimization problem concerns designing the layout of material within a given region of space so that some performance measure is extremized. To improve manufacturability and reduce manufacturing costs, restrictions on the possible… read more here.

Abstract: Abstract Topology optimization is a powerful tool for designing high-performance structures. However, the structures resulting from topology optimization usually have complex geometries , which makes them difficult or costly to fabricate. As a result, topology… read more here.

Abstract: We consider spacetime endowed with a zero point length, i.e. with an effective metric structure which allows for a (quantum-mechanically arising) finite distance $L_0$ between events in the limit of their coincidence. Restricting attention to… read more here.
