In this paper we present a new hybrid heuristic for large geometric Traveling Salesman Problems. The method is based on the use of the Delaunay Triangulation of a set of cities. Many heuristics for the TSP are generally composed of two phases: a constructive heuristic followed by an iterative improvement step until a local minimum is reached. We think of this heuristic as a hybrid since, after ...

The main purpose of this paper is to throw some light on applied strategies at an idiomatic expressional level in a contrastive analysis framework by investigating the cultural-bound Brida novel Paulo Coelho from English translation into Persian. It worthy point out that theoretical present based Baker’s (2011) model rendering expressions. Further, within text, there are certain comparisons whi...

Purpose This paper develops a theoretical model that analyzes the decision problem landowner has to face between construction of second homes and hotels. The starting point implies verifying for given tourist destination, land available accommodation is limited. For this reason, when choosing building or hotels, many factors influence model. mechanism generalizes introduced in Brida Boffa (2010...

Matters regarding very important, because is one of most important measures organizational quality. One factors affect employee environment compet...

AIM Hepatobiliary scintigraphy is an integral part in the diagnostic work-up of the neonatal cholestasis syndrome. However, less than optimal specificity is its major disadvantage. Differentiation between biliary atresia and neonatal hepatitis is nearly impossible in some cases with poor hepatocellular function. 99mTc sestamibi (MIBI) is a cationic lipophilic agent which is a substrate of P-gly...

Helicobacter pylori and duodenogastric reflux are both recognised as playing aetiological roles in chronic gastritis. This study investigated whether H pylori colonisation of the antral mucosa and duodenogastric reflux are independent phenomena or have a causal relationship. Thirty eight patients (15 men, 23 women) aged (mean (SD)) 48 (17) years participated. Each patient underwent gastroscopy....

With the purpose to introduce a useful tool for researches concerning foundations of quantum mechanics and applications to quantum technologies, here we study three quantumness quantifiers for bipartite optical systems: one based on sub-shot-noise correlations, one related to antibunchThis work has been supported by SanPaolo Foundation, Quantum Candela EU Project G. Brida Istituto Nazionale di ...

In this paper we extend the study done by Ferrara and Guerrini [12], where two different research lines within the Ramsey model were joined together: the one studying the role of a logistic population growth rate (Accinelli and Brida [2]), and the one analyzing the effects of a Benthamite formulation for the utility function. The results obtained in [12] for the special case of a constant inter...
