High-Thermal-Conductivity SiC Ceramic Mirror for High-Average-Power Laser System
Crystals, 2020 The importance of heat-resistant optics is increasing together with the average power of high-intensity lasers. A silicon carbide (SiC) ceramic with high thermal conductivity is proposed as an optics substrate to suppress thermal effects. The temperature

An average case analysis of the minimum spanning tree heuristic for the range assignment problem [PDF]
, 2007 We present an average case analysis of the minimum spanning tree heuristic for the range assignment problem on a graph with power weighted edges. It is well-known that the worst-case approximation ratio of this heuristic is 2.

An Average Power Primer: Clarifying Misconceptions about Average Power and Replicability
The replication crisis heightened interest in methods for assessing the credibility of published research. One approach to evaluate published results is to estimate the average power of original studies based on observed data. Recent criticisms, however, have challenged the validity and usefulness of this approach, arguing that it involves a ...
