Background: Ankle injuries are one of the most common complaints of patients presenting to emergency departments (ED). The Ottawa ankle rules (OAR) was introduced to help physicians to decide who may require x-ray for blunt injuries. The present study aimed at validating the four steps weight-bearing rule of OAR as a sole criterion.    Methods: This prospective observational study wa...

There are many methods introduced to solve the credit scoring problem such as support vector machines, neural networks and rule based classifiers. Rule bases are more favourite in credit decision making because of their ability to explicitly distinguish between good and bad applicants.In this paper multi-objective particle swarm is applied to optimize fuzzy apriori rule base in credit scoring. ...

Recently, tuning the weights of the rules in Fuzzy Rule-Base Classification Systems is researched in order to improve the accuracy of classification. In this paper, a margin-based optimization model, inspired by Support Vector Machine classifiers, is proposed to compute these fuzzy rule weights. This approach not only  considers both accuracy and generalization criteria in a single objective fu...

Two series of novel boron difluoride adducts (BDFs), namely [BF(2)(OO(R(n)))] (type I) and [BF(2)(OO(2R(n)))] (type II) (R = C(6)H(4)OC(n)H(2n+1); n = 10-18), containing β-diketonate ligands bearing 4-alkoxyphenyl substituents in position 1 or in positions 1,3 of the β-diketonate core, respectively, have been prepared. All of them display a strong interaction between the ligand and the BF(2) gr...

Although barriers to international investment have fallen sharply over the last 60 years, positive impact of financial globalization has proved far more limited than expected. Predictions by economists (including author) that cross-country differences in and financing would narrow or even disappear largely failed materialize. Investors everywhere continue hold disproportionate amounts domestic ...

After more than one century from its first use for electric power production, steam cycles are still the object of continuous research and development efforts worldwide. Indeed, owing to favorable thermodynamic properties, not only used in coal-fired plants but a large variety applications such as combined cycles, concentrated solar polygeneration plants. On other hand, cope with efficiency fle...
