This article deals with the power-sharing control of bearingless multisector and multithree-phase permanent magnet machines. The proposed strategy allows to distribute power flows among three-phase inverters supplying machine during operation drive. technique is based on extension vector space decomposition modeling approach. components producing electromagnetic torque, i.e., <italic xmlns:mml=...

The single-stage scheduling problem to minimize the makespan of identical jobs on uniform parallel machines is known to be solvable in polynomial-time. We extend this work to consider multi-stage systems with flowshop configuration. We show that the 2-stage problem may also be solved in polynomial-time and for the number of stages greater than two, the problem is shown to be NP-hard. We present...

In this paper we introduce the concepts of multi-level machines and of multi-level dynamic programung. These machines are well suited for the difficult continuous speech recognition problem because firstly, they permit the integration of several knowledge sources, secondly, they allow an optimal search based on dynamic programmng and thirdly, they can deal with semantic constraints. Furthermore...

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...

There are a number of new high intensity proton synchrotrons proposed: the SNS[6] at Oakridge and ESS[7] in Europe, as neutron sources; the JHF/NSP[9] in Japan, a multi-disciplinary facility sponsored by KEK and JAERI; the New FNAL Booster[5]; and the Proton Driver[4, 8] as first stage of a μ − μ collider. In addition there are operating machines such as ISIS[1] at RAL, the Brookhaven AGS[3] an...

In today’s competitive business environment, the design and management of supply chainnetwork is one of the most important challenges that managers encounter. The supply chain network shouldbe designed for satisfying of customer demands as well as minizing the total system costs. This paper presentsa multi-period multi-stage supply chain network design problem under demand uncertainty. The prob...

In this work we address the use of support vector machines in multi-category problems. In our case, the objective is to classify eight different inds of alcohols with just one SnO2 sensor using thermomodulation. The use of support vector machines in the field of sensors signals recognition s beginning to be used due to the ability to generalize in a binary classification problem with a small nu...

Transaction management is an essential component of database management systems. It enables multiple users to access the database concurrently while preserving transactional properties such as atomicity, consistency, isolation, and durability. In this paper, we propose a formal framework specification for transaction processing. Our work can be seen as an extension of previous work by Gurevich ...
