Photoluminescence of Mechanochemically Manufactured Rare‐Earth Doped CsPbCl3 Microcrystals

Advanced Photonics Research, EarlyView.
The mechanochemical approach presented in this work allows for exceptional control over dopant incorporation, producing high‐quality powders suited to melt‐growth of single crystals. Through complementary structural characterization techniques (X‐ray diffraction, energy‐dispersive X‐ray spectroscopy, and X‐ray fluorescence), the nominal doping ...

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

A new solution to the K-shortest paths problem and its application in wavelength routed optical networks [PDF]

Photonic Network Communications, 2006
In communication networks, traffic carried over long paths suffers from a higher call blocking probability (CBP) than those carried over short paths. This is a well-known fairness problem. Such a problem becomes more serious in wavelength-routed optical networks (WRONs) due to the wavelength continuity constraint.

Transmission Line Route Selection: An Application of K-Shortest Paths and Goal Programming

IEEE Power Engineering Review, 1984
A two-stage solution procedure is developed as a managerial decision making tool in the transmission line route selection process. In stage one, the K least costly alternatives are found, based strictly on monetary considerations. In stage two, the alternative which causes the least amount of social and environmental disruption is selected from the ...

Ak-SHORTEST PATHS ROUTING HEURISTIC FOR STOCHASTIC NETWORK EVACUATION MODELS

Engineering Optimization, 1984
Stochastic-network evacuation models require an optimization process to determine the best evacuation routes for a building's occupants. The optimization process developed and applied below is a heuristic based on the K-th Shortest Path Algorithm.

Comparison of k-shortest paths and maximum flow routing for network facility restoration

IEEE Journal on Selected Areas in Communications, 1994
In the development of technologies for span failure restoration, a question arises about the restoration rerouting characteristics to be specified. In theory, maximal rerouting capacity is obtained with a maximum flow (Max Flow) criterion. However, rerouting that realizes the k-successively shortest link disjoint paths (KSP) may be faster, easier, and,
