Metric Dimension for Gabriel Unit Disk Graphs is NP-Complete [PDF]
, 2013 We show that finding a minimal number of landmark nodes for a unique virtual addressing by hop-distances in wireless ad-hoc sensor networks is NP-complete even if the networks are unit disk graphs that contain only Gabriel edges.

CFD analysis and experimental comparison of novel roof tile shapes
Propulsion and Power Research, 2017 In tiled pitched roofs, a ventilated layer reduces the heat transfer between tiles and roof structure by means of natural and forced convection, thereby also reducing the cooling energy requirement.

Tunable Digital Material Properties of 3D Voxel Printers [PDF]
, 2008 Digital materials are composed of many discrete voxels placed in a massively parallel layer deposition process, as opposed to continuous (analog) deposition techniques.

, 2020 We study the uniqueness of optimal solutions to extremal graph theory problems. Lovasz conjectured that every finite feasible set of subgraph density constraints can be extended further by a finite set of density constraints so that the resulting set is ...

Undecidability of the Spectral Gap (full version)
, 2020 We show that the spectral gap problem is undecidable. Specifically, we construct families of translationally-invariant, nearest-neighbour Hamiltonians on a 2D square lattice of d-level quantum systems (d constant), for which determining whether the ...

A Toom rule that increases the thickness of sets [PDF]
, 1990 Toom's north-east-self voting cellular automaton rule R is known to suppress small minorities. A variant which we call R^+ is also known to turn an arbitrary initial configuration into a homogenous one (without changing the ones that were homogenous to ...

SiPMs for cryogenic temperature [PDF]
, 2019 The DarkSide-20k collaboration is preparing to equip 20 m^2 of SiPMs working in liquid argon at 86 K for the direct search of WIMPs. The collaboration had to solve many technological aspects, such as the development of SiPM optimized for operation in ...
