Abstract: Disclosed are devices, systems and methods for routing and scheduling based on family column generation (FCG). The described embodiments provide a dual stabilization method that accelerates column generation (CG), thereby decreasing the number of iterations of CG needed to solve the problem. An example method includes receiving information associated with each of the plurality of facilities, receiving a plurality of demands associated with each of the plurality of customers, generating, based on the information and the plurality of demands, a facility location problem, splitting the facility location problem into a master problem and a subproblem, and iteratively solving, using a FCG method, the master problem and the subproblem to generate the solution comprising assignments between the plurality of customers and the subset of the plurality of facilities that minimize the total cost.

Abstract: Disclosed are devices, systems, and methods for routing and scheduling using column generation (CG)-based techniques. The described embodiments include dual optimal inequalities that incorporate detours (referred to as detour-DOI), graph generation (GG), principled graph management (PGM), and column generation with local area (LA) route relaxations. These CG-based techniques can be applied to a variety of logistical optimization problems that include, but are not limited to, the facility location problem, the capacitated vehicle routing problem (CVRP), the CVRP with time windows, multi-robot routing (both with and without time windows), the bus driver scheduling problem, the supply chain scheduling problem, the shift/workforce scheduling problem, and the grocery picking for micro-fulfillment problem.

Abstract: A conformal retro-modulator optical apparatus. The apparatus includes an array of multiple quantum well devices disposed in a thin array. A plastic support element is bonded to the thin array, the plastic support element having a thickness greater that of the thin array. The plastic support element is preferably plastic at elevated temperatures above room temperature, thereby allowing the plastic support element and the thin array of multiple well device disposed therein to conform to a predetermined shape, yet being rigid at room temperature.

Abstract: A photo-EMF detector including a shield to prevent a portion of the detector from illumination. The shield prevents the generation of unwanted noise-currents, thus increasing the performance of the photo-EMF detector.

Abstract: A remote mass is excited with one or more beams, and the surface vibrations of the excited mass are detected with one or more laser vibrometers. Each vibrometer generates a signal indicative of the surface vibrations which is stored, reversed in time, and applied to modulate an exciter beam that is then impinged onto the mass.

Abstract: A method and apparatus for detecting spectral properties of a sample are disclosed. Electromagnetic radiation in the Terahertz range emitted from a first laser source is modulated and combined with electromagnetic radiation emitted from a second laser source. The frequency spectrum of the combined signal comprises sidebands which can be tuned to resonate with the frequency spectrum of the sample. Tuning of the sidebands is obtained by tuning the first laser source, the second laser source, or the modulation frequency.
