We propose efficient implementations of Seymour and Thomas algorithm which, given a planar graph and an integer β, decides whether the graph has the branchwidth at least β. The computational results of our implementations show that the branchwidth of a planar graph can be computed in a practical time and memory space for some instances of size about one hundred thousand edges. Previous studies ...

This paper proposes a reconfigurable parallel architecture for space-borne on-board processing that combines the advantages of powerful computational resources with a straightforward software development. This approach introduces the concept of software payloads that enable the users the direct transfer of their ground-based applications towards space and thus the circumvention of the usual dow...

Chip-multiprocessors (CMPs) are quickly becoming entrenched as the main-stream architectural platform in computer systems. One of the critical challenges facing CMPs is designing applications to effectively leverage the computational resources they provide. Modifying applications to effectively run on CMPs requires understanding the bottlenecks in applications, which necessitates a detailed und...

To the Editor:—We read with interest the article by Smith et al., and we congratulate the authors on increasing both major joint arthroplasty throughput and profitability by implementing a parallel processing system. In their model, the authors describe the anesthesia induction room as either an “underutilized operating room (OR)” or “a shared induction area bed space.” If at all possible, howe...

No extra-hospitalar, a formação de profissionais foca-se, essencialmente, em competências técnicas, atribuindo pouca importância às não que contribuem para excelência do desempenho das equipas. O Crew Resource Management (CRM) é utilizado como ferramenta desenvolvimento técnicas na aviação. Objetivo: Evidenciar necessidade específica contínua o extra-hospitalar. Metodologia: Foi realizada uma r...

Background The implications of decentralisation on human resource for health management has not received adequate research attention despite the presupposition that the concept of decentralisation leads to the transfer of management authority and discretion for human resource management from national levels to subnational levels. This study aims at investigating the extent to which decent...

In the title compound, [Ba(C(14)H(20)O(5))(2)][Co(NCS)(4)], the Ba(II) and Co(II) ions are situated on twofold rotational axes, so asymmetric unit contains half each of the complex cations and anions. The Co(II) ion is coordinated by four N atoms [Co-N 1.83 (2), 1.95 (3) Å] in a distorted tetra-hedral geometry. The Ba(II) ion is coordinated by ten O atoms [Ba-O 2.766 (19)-2.859 (19) Å] from two...

We provide efficient algorithms for two major problems in network analysis. One is the Graph Center (GC) problem and the other is the Graph Bottleneck (GB) problem. The GC problem is relevant for facility location, while the GB problem is relevant for transportation and logistics. The GC problem is to identify a pre-determined number of center vertices such that the distances or costs from (or ...
