The job-shop scheduling problem is one of the most difficult problems in scheduling. This paper presents an improved constraint satisfaction adaptive neural network for job-shop scheduling problems. The neural network is constructed based on constraint conditions of a job-shop scheduling problem. Its structure and neuron connections can change adaptively according to the real-time constraint sa...

Chipping in glass plates from line-wedge contact loading is studied as function of the wedge’s subtended angle 2β, its inclination angle φ, and the distance h from a corner having a subtended angle 90◦−θ . A brittle-fracture analysis in conjunction with the FEM technique is used to elucidate the role of geometric variables on chip morphology and chipping load. Closedform relations are developed...

Crack propagation across laminated brittle solids from uniaxial tension or line-wedge loading is studied in real time using a model glass/epoxy architecture. The fracture progresses from one layer to the next via reinitiation from pre-existing flaws on the glass surfaces ahead of the primary crack in a process accompanied by some penetration through the interlayer but generally little or no del...

In this study, a simple, reliable and accurate method for the simultaneous separation and determination of naringin, hesperidin, neohesperidin, baicalin, wogonoside, baicalein, wogonin, emodin and chrysophanol in ‘Da-Chai-Hu-Tang’ was developed by reverse-phase high-performance liquid chromatography (RP-HPLC). The chromatographic separation was performed on an Agilent ZORBAX C18 column (250 mm ...

In [Cha00] Chai made a conjecture on the codimensions of Newton strata in Shimura varieties, which then led Rapoport [Rap05] to his conjecture on dimensions of affine Deligne-Lusztig varieties inside affine Grassmannians. The main goal of this paper is to show that exactly the same codimensions arise in a simpler context, that of the Newton stratification in the adjoint quotient of a reductive ...
