this article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. the objective is to minimize the makespan for a given set of jobs in the system. this problem class is np-hard in the strong sense, so a hybrid heuristic method for sequencing and then allocating operations of jobs to machines is developed. a number of test problems are randomly ge...

Mere familiarity does not necessarily produce understanding. It is perfectly possible to know something (or someone!) all your life and still never really comprehend what you're dealing with. Like the Irishman in the old joke who received a brand-new toilet from his American cousins: He used the bowl for a foot washer, the lid for a breadboard, and the seat for a frame around the Pope's picture.

In this paper, we propose a physically based model for the printing process in the virtual woodblock printing for improvement of printing quality. Virtual printing is a simulation of real printing using “woodblocks”, “a paper sheet”, “a BAREN (Japanese squeegee)”, and “inks” in a virtual 3D space. A print is synthesized by an interaction among them, and it is very important to study physical pr...

Electrohydrodynamic (EHD) jet printing is a direct-writing technique which ejects ink through a fine nozzle using an electric field, which has the advantages of high-resolution, rapid printing speed and a wide range of ink selectivity. In this article, the EHD jet printing system is utilized to print patterns of polystyrene (PS) nanofibers. The effect of parameters such as ink concentration, wo...

Interest in 3D printing has greatly increased since 2013. With 3D printing high part complexity at no additional costs can be achieved, beside of efficiently using the raw material. This article reviews recent developments in 3D printing, with respect to the use of wood. Three examples are given on how wood could come to 3D printing: development of bio-based filaments, printing wood-like 3D obj...

Sensor and Information fusion is recently a major topic, not only in traffic management, military, avionics, robotics, image processing, and e. g. medical applications, but becomes more and more important in machine diagnosis and conditioning for complex production machines and process engineering. Several approaches for multi-sensor systems exist in the literature, cf. (Hall & Llinas, 2001); (...
