The emergence of many-core and massively-parallel computational accelerators (e.g., GPGPUs) has led to user demand for such resources in grid infrastructures. A widely adopted approach for discovering and accessing such resources has, however, yet to emerge. GPGPUs are an example of a larger class of computational resources, characterized in part by dependence on an allocated CPU. This paper terms such resources “CPU-Dependent Execution Resources” (CDERs). Five conceptual strategies for discovering and accessing CDERs are described and evaluated against key criteria, and all five strategies are compliant with GLUE 1.3, GLUE 2.0, or both. From this evaluation, two of the presented strategies clearly emerge as providing the greatest flexibility for publishing both static and dynamic CDER information and identifying CDERs that satisfy specific job requirements. Furthermore, a two-phase approach to job-submission is proposed for those jobs requiring access to CDERs. The approach is compatible with existing grid services. Examples are provided to illustrate job submission under each strategy.

The purpose of this paper is to identify and analyze strategy towards Thailand production service industry. Various tools are applied in the paper, including five force analysis, diamond of nation, and sense and respond method with CFI models. The analysis results show that Thai fine gold jewellery exporter should concern on value added and customer requirement; focus on product development, networking, cooperation between Thai organizers and lobbying; pay more attention to marketing orientation than personal judgment. The benefit of combining five force and diamond of nation model to analyse the strategic condition can be proved in this study.

Ludzkie oko jest poddawane ekspozycji na toksyczne promieniowanie ultrafioletowe, pochodzące tak z naturalnego światła słonecznego, jak i ze sztucznych źródeł. Nie ma wątpliwości, że UV stanowi zagrożenie dla oka, powodując uszkodzenia i choroby w wielu strukturach oka, od powierzchni rogówki do siatkówki (Bergmanson i Söderberg 1995), chociaż rogówka i soczewka powinny zapewniać wrodzoną ochronę przed promieniowaniem UV (Boettner et al. 1962, Sliney 2002, Walsh et al. 2008).
