The production task queue has a great significance for manufacturing resource allocation and scheduling decision. Man-made qualitative queue optimization method has a poor effect and makes the application difficult. A production task queue optimization method is proposed based on multi-attribute evaluation. According to the task attributes, the hierarchical multi-attribute model is established ...

We consider the problem of existence of entire solutions to the Allen-Cahn equation Δu + u - u(3) = 0 in , usually regarded as a prototype for the modeling of phase transition phenomena. In particular, exploiting the link between the Allen-Cahn equation and minimal surface theory in dimensions N ≥ 9, we find a solution, u, with ∂(x(N))u > 0, such that its level sets are close to a nonplanar, mi...

We study a singular limit problem of the Allen-Cahn equation with Neumann boundary conditions and general initial data of uniformly bounded energy. We prove that the time-parametrized family of limit energy measures is Brakke’s mean curvature flow with a generalized right angle condition on the boundary.

A myriad of ophthalmic disorders is associated with the phenotype of Down syndrome including strabismus, cataracts, and refractive errors potentially resulting in significant visual impairment. Ophthalmic sequelae have been extensively studied in children and adolescents with Down syndrome but less often in older adults. In-depth review of medical records of older adults with Down syndrome indi...

1.0 ABSTRACT The Advanced Communications Technology Satellite (ACTS) program was slated for decommissioning in October 2000 as was announced at the 6 th Ka-band Utilization Conference in May 2000. Quite a celebration was had at that event too centering on the decommissioning of this very successful technology program [ 1]. With plans in place to move the spacecraft to an orbital graveyard and t...

Much of the academic literature that investigates energy planning focuses on development plans but overlooks how they shape actors’ situated sensemaking in field. This paper followed process realizing a sector-coupling investment thermal storage Copenhagen from 2017 to 2020. The analysis shows while may help define technological qualities and purposes, do not always convince actors. Plans simul...

The IT Plan is generally seen as a cornerstone of the IS/IT presence in an organisation. Researchers have outlined various approaches to IT planning and many have suggested categorising such plans in terms of an evolutionary model detailing the degree of integration with organisational business plans. To determine how IT plans are developed in practice and the actual forces at play the study in...
