This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...

Since the first experimental observation of optical Airy beams, various applications ranging from particle and cell micromanipulation to laser micromachining have exploited their nondiffracting accelerating properties. The later discovery that beams can self-heal after being blocked by an obstacle further proved robustness propagate under a scattering disordered environment. Here, we report gen...

Optical isolators are indispensable components of almost any optical system and used to protect a laser from unwanted reflections for phase-stable coherent operation. The emergence chip-scale systems, powered by semiconductor lasers that integrated on the same chip, has generated demand fully isolator. Conventional approaches, which rely use magneto-optic materials break Lorentz reciprocity, pr...

    Dynamic cellular manufacturing systems,   Mixed-integer non-linear programming,   Production planning, Manufacturing attributes   This paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (DCMS) based on production planning (PP) decisions and several manufacturing attributes. Such an integrated DCMS model with an extensi...

toxic optic neuropathy (ton) is a group of medical disorders which can be defined by visual impairment due to optic nerve damage by a toxin. the exposure to a toxic substance can occur at the workplace, with ingestion of materials/ foods containing a toxin, or the use of systemic medications. ton is a disease entity which is not only under-diagnosed, but also often diagnosed at a stage when rec...

Optic neuropathies, such as glaucoma and Leber's hereditary optic neuropathy (LHON) lead to retinal ganglion cell (RGC) loss and therefore motivate the application of transplantation technique into disease therapy. However, it is a challenge to direct the transplanted optic nerve axons to the correct location of the retina. The use of appropriate scaffold can promote the proper axon growth. Rec...
