in a region, optimal allocation of lands to various agricultural products is one of the most important issue associated with optimal use of agricultural resources. meta-goal programming is one of the multiple criteria decision models. this programming provides more flexible decisions for decision makers than other goal programming. in the current study, optimal cropping pattern was determined u...

The ultimate goal of metamaterial engineering is to have complete control over the electromagnetic constitutive parameters in three-dimensional space. This engineering can be done by considering either single meta-atoms or full meta-arrays. We follow the first route and perform numerical simulations of split-ring resonators, with different gap numbers and under varying illumination scenarios, t...

OBJECTIVE To examine whether the exclusion of individual treatment comparators, including placebo/no treatment, affects the results of network meta-analysis. DESIGN Survey of networks with individual trial data. DATA SOURCES PubMed and communication with authors of network meta-analyses. STUDY SELECTION AND METHODS We included networks that had five or more treatments, contained at least ...

The increasing openness and heterogeneity of distributed computing systems requires the representation of meta-information in distributed environments. Most type management systems can only define types within particular type systems. In contrast, the DSTC’s Meta-Object Facility (MOF) first defines a type system as a set of meta-meta-objects, and then defines types as meta-objects which are des...

Two studies examined the compensation hypothesis that members of both highand low-status groups associate high-status groups with high levels of competence and low levels of warmth on the one hand, and low-status groups with low levels of competence and high levels of warmth, on the other. Building upon existing linguistic relations between the French and the Belgians, Study 1 had standard, i.e...

OBJECTIVE To establish the extent to which systematic reviews and meta-analyses of individual participant data (IPD) are being used to inform the recommendations included in published clinical guidelines. DESIGN Descriptive study. SETTING Database maintained by the Cochrane IPD Meta-analysis Methods Group, supplemented by records of published IPD meta-analyses held in a separate database. ...

Network meta-analysis provides a global estimate of comparative treatment effectiveness combining both direct and indirect evidence. In the past decade, the medical literature has witnessed a rapid increase in the possibility to combine evidence from different treatment comparisons. This opportunity is attractive for clinicians since their major concern is to identify the single best available ...

Purpose – The Robots.txt and Robots Meta tags constitute a set of instruments that can be used to instruct software robots. However, the current version of Robots.txt and Robots Meta tags are both too simple and ambiguous in an internet world with many potential conflicts, especially in terms of copyright and trespass to chattels. This paper seeks to propose an amendment to the Robots.txt and R...

The existing resource and topology heterogeneity has divided the scheduling solutions into local schedulers and high-level schedulers (a.k.a. meta-schedulers). Although much work has been proposed to optimise job queue based scheduling, seldom has attention been put on the job sharing behaviours between decentralised distributed resource pools, which in turn raises a notable opportunity to expl...

Deploying lightweight tasks individually on grid resources would lead to a situation where communication overhead dominates the overall application processing time. The communication overhead can be reduced if we group the lightweight tasks at the meta-scheduler before the deployment. However, there is a necessity to limit the number of tasks in a group in order to utilise the resources and the...
