This paper describes a feature-based approach to automated design of multi-piece sacrificial molds. We use multi-piece sacrificial molds to create complex 3D polymer/ceramic parts. Multipiece molds refer to molds that contain more than two mold components or subassemblies. Our methodology has the following three benefits over the state-of-the-art. First, by using multi-piece molds we can create...

As a breakthrough in the cost and durability of molds for nanoimprint lithography (NIL), replica molds are fabricated by injection compression molding (ICM). ICM is commonly used for optical disks such as DVDs or Blu-ray disks and is also a practical fabrication method for nanostructures. In this paper, I successfully demonstrated the fabrication of cycloolefin polymer replica molds with struct...

The in vitro activity of voriconazole was compared with that of itraconazole. Eighty-six isolates of pathogenic molds belonging to 23 species were tested by an agar dilution method in High Resolution medium. Voriconazole was more active than itraconazole against a number of hyaline molds, including several Fusarium spp. and Scedosporium prolificans. Voriconazole and itraconazole showed comparab...

Organizational design affects performance via coupled search processes. At low frequency, managers search for appropriate organizational designs. At higher frequency, managers use designs to search for high-performing operational choices. The two searches are coupled: organizational design molds the choice among operational alternatives, and performance feedback from operational choices shapes ...

Multi-Piece molds, which consist of more than two mold pieces, are capable of producing very complex parts⎯parts that cannot be produced by the traditional molds. The tooling cost is also low for multi-piece molds, which makes it a candidate for pre-production prototyping and bridge tooling. However, designing multi-piece molds is a time-consuming task. This paper describes geometric algorithms...

What is Physarum? Physarum, or more precisely Physarum polycephalum, is an acellular slime mold, or myxogastrid. Myxogastrids are closely related to the cellular slime molds, or dictyostelids, including the well known Dictyostelium discoideum. Physarum is more distantly related to the protostelids (together these groups are discussed as the eumycetozoans, or ‘true’ slime molds) and very distant...
