We consider flowshop environments that consist of multiple stages and multiple machines in each stage. The flowshops are flexible in the sense that a task within a stage can be processed by any of the machines in the stage. We refer to this design as the hybrid flowshop. Our objective is to schedule a set of n jobs so as to minimize makespan. The problem is NP-complete even in the case of a sin...

to study combining ability and genetic parameters of seed yield trait in rapeseed, eight lines of rapeseed were evaluated by a design of half diallel cross. seeds of f1 generation and their parents were grown in a 6 × 6 simple lattice design with two replications. according to the analysis of variance, general combining ability (gca), specific combining ability (sca) and mean squares of genotyp...

Interspecific hybrid incompatibility, including inviability and sterility, is important in speciation; however, its genetic basis remains largely unknown in vertebrates. Crosses between male chickens and female Japanese quails using artificial insemination can generate intergeneric hybrids; however, the hatching rate is low, and hatched hybrids are only sterile males. Hybrid development is arre...

A simulation study consists of several well-defined stages, e.g., problem formulation, model implementation and experimentation. The application of multiple techniques in the model implementation stage is referred to as hybrid simulation, which we distinguish in this paper from a hybrid M&S study, the latter referring to studies that apply methods and techniques from disciplines like Operations...

We address the question of whether unbarred market entry can eliminate monopolizing behavior in the presence of acquisitions. We model this question by using a four-stage repeated noncooperative game. Analysis of subgame perfect pure strategy Nash equilibria of this game under simplifying assumptions …nds that even with entry and the absence of collusion, competitive acquisition of …rms by thei...

Background. Lessons learned during the developme f a novel hybrid approach have resulted in a reli eproducible alternative treatment for hypoplastic l eart syndrome (HLHS). Herein we report our res sing this hybrid approach in a uniform risk cohort Methods. This is a review of prospectively collec ata on patients treated for HLHS using a hybrid roach (n 40) between July 2002 and June 2007. T yb...

The two-robot entry from the University of South Florida received a Technical Innovation Award for Conceptual and Artistic Design in the Hors d’Oeurves Anyone? event of the 1999 AAAI Mobile Robot Competition. The entry was fielded by a team of seven students from the Computer Science and Engineering and Art departments. Three of the team members were undergraduates. The robots were unique in th...
