In order to address skill shortages and the demographic challenges facing the EU, member states have to attract (and retain) the more skilled migrants. Nevertheless, foreign residents generally find a significant wage gap with respect to native-born workers when arriving in a host country. Favourable integration policies seem to improve the relative performance of immigrants in the labour marke...

As high performance computing clusters are getting cheaper, they become more accessible. The various clusters are running a host of workload management software suites, which are getting more complex and offer cluster administrators numerous features, scheduling policies, job prioritization schemes, etc. In this paper we survey some of the common commercial workload managers on the market, cove...

buchitic glassy rocks appear within the skarn of contact metamorphic aureole of feshark intrusive complex situated 30 km northeast of isfahan. intrusive complex is a multistage intrusion . noritic gabbro is the first inttrusion which is invaded later on by a granitic melt. granitic melt has metasomatically altered the gabbro and as a consequence a suite of hybrid rocks like monzogabbro, monzodi...

The aim of this work was to delineate the prospects of podiform-type chromite by staged factor analysis and geochemical mineralization prospectivity index in Balvard area, SE Iran. The stream sediment data and fault density were used as the exploration features for prospectivity modeling in the studied area. In this regard, two continuous fuzzified evidence layers were generated and integrated ...

We consider a distributed server system model and ask which policy should be used for assigning tasks to hosts. In our model each host processes tasks in First-Come-First-Serve order and the task's service demand is known in advance. We consider four task assignment policies commonly proposed for such distributed server systems: RoundRobin, Random, Size-Based, in which all tasks within a give s...

Chlorite flakes, as a product of alteration of biotite, the dominant ferromagnesian mineral in the Paleozoic granitic rocks of the Canadian Appalachians, have been analyzed by electron microprobe for major elements and by 57Fe M?ssbauer spectroscopy for the coordination and oxidation state of Fe. Comparison of M?ssbauer Fe3+/Fe ratios obtained from chlorite and its host biotite indicates that c...

An efficient access to the contents provided through OGC web services, widely used in environmental information systems, is usually achieved by means of caching strategies. Service-owners may be interested in expressing the conditions required to allow for this. If these conditions are expressed in a machine-readable way, automatic harvesters can be programmed to follow them when caching those ...
