Abstract: An important traffic engineering problem for OSPF networks is the determination of optimal link weight system for a given objective function such as the Fortz-Thorup (FT) piece-wise linear convex function. In this paper, we show that the optimal link weights are obtained from the slopes of the FT function when approached from the dual space. This also suggests that the slopes can be a...

In this paper,  fuzzy convergence theory in the framework of $L$-convex spaces is introduced. Firstly, the concept of $L$-convex remote-neighborhood spaces is introduced and it is shown that the  resulting category is isomorphic to that of $L$-convex spaces. Secondly, by means of $L$-convex ideals, the notion of $L$-convergence spaces is introduced and it is proved that the  category of $L$-con...

When tests are conducted on the field slope under artificial rainfall, because rainfall is often limited to implementation in mode of local there a boundary constraint effect between area and non-rainfall area, which manifested lateral infiltration rainwater deformation retardation area. Firstly, deep-buried isolated trench was proposed solve these constraints. Then, cracking corresponding nume...

  Background: Open Bankart surgery is the main treatment procedure in patients with recurrent anterior shoulder dislocation, especially in cases with glenoid bone defect. The goal of this study was to determine the outcomes after open Bankart surgery in cases of recurrent anterior shoulder dislocation with glenoid bone defects and concomitant Hill-Sachs lesions. Methods: Between 2006 and 2010,...

This article systematically explores cue integration within active touch. Our research builds upon a recently made distinction between position and force cues for haptic shape perception: when sliding a finger across a bumpy surface, the finger follows the surface geometry (position cue). At the same time, the finger is exposed to forces related to the slope of the surface (force cue). Experime...

In this paper, the effects of a time varying delay on a chaotic drive-response synchronization are considered. Using a delayed feedback proportional-derivative (PD) controller scheme, a delay-dependent synchronization criterion is derived for chaotic systems represented by the Lur’e system with sector and slope restricted nonlinearities. The derived criterion is a sufficient condition for the a...

Background: Oxford Shoulder Score (OSS) is a specific questionnaire for the assessment of pain and function in subjects with shoulder pain. The reliability and validity of the Persian version of this questionnaire have been shown previously. But its responsiveness has not been investigated yet. This study aimed to determine the Persian OSS responsiveness in subjects with shoulder pain. Methods...

We revisit recent results about optimal periodic control for scalar dynamics with input integral constraint, under lack of convexity and concavity. show that in this more general framework, the solutions are bang-singular-bang generalize bang-bang convex case purely singular concave one. introduce a non-local slope condition to characterize arcs. The illustrated on class bioprocesses models.

in this paper, the concept of fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) of an ordered group (resp. lattice-ordered group) is introduced and some properties, characterizations and related results are given. also, the fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) generated by a fuzzy subgroup (resp. fuzzy subsemigroup) is characterized. furthermore,...

This study aimed to evaluate the shoulder dislocation following tramadol-induced seizure and its potential difference with other shoulder dislocations. We evaluated six cases that used tramadol tablets and some of them had a history of seizure. All of the cases had shoulder dislocation. According to the findings, tramadol use and tramadol-induced seizure may increase the risk of shoulder disloc...
