stroke patients with proximal occlusions of the main stems of cerebral arteries are no optimal candidates for i. v. thrombolysis. for many years interventional stroke treatment could not be established as alternative. this changed with the introduction of stent retrievers and flexible large lumen aspiration catheters. randomized trials now proved a significant benefit from intervention for a wi...

introduction: advantages of endodontic treatments over tooth extraction have increased the demands for these treatments. success rate of these treatments is generally lower than the primary root canal therapies. recently, single visit treatments have gained more popularity. but, the influence of completing retreatment in a single appointment on success of the treatment is still a controversy. t...

World action in medical education, notably the global programs of the World Federation for Medical Education, the Edinburgh Declaration of 1988 and the 1993 World Summit, has led to major curricular change in medical schools. For educational reform to result in improved health services of nations, an essential requirement is integration between the medical education system and the health care d...

SUMMARY Automatic optimum network design for measuring complex industrial objects by vision metrology systems is a real challenge. In the absence of 3D simulated CAD models of the complex objects along with the absence of workspace information, several uncertain parameters are introduced into the camera placement decision-making process. These uncertain factors include the vision constraints su...

In a typical multitarget tracking (MTT) scenario, the sensor state is either assumed known, or tracking is performed based on the sensor’s (relative) coordinate frame. This assumption becomes violated when the MTT sensor, such as a vehicular radar, is mounted on a vehicle, and the target state should be represented in a global (absolute) coordinate frame. Then it is important to consider the un...

Motivated by the challenges encountered in sawmill production planning, we study a multi-product, multi-period production planning problem with uncertainty in the quality of raw materials and consequently in processes yields, as well as uncertainty in products demands. As demand and yield own different uncertain natures, they are modeled separately and then integrated. Demand uncertainty is con...

Given the uncertain market demands and capacities in production environment, this paper discusses some practical approaches to modeling multiproduct aggregate production planning problems with fuzzy demands, fuzzy capacities, and financial constraints. By formulating the fuzzy demand, fuzzy equation, and fuzzy capacities, a fuzzy production-inventory balance equation for single period and a dyn...

Unlike its deterministic counterpart, static and stochastic vehicle routing problems (SSVRP) aim at modeling and solving real-life operational problems by considering uncertainty on data. We consider the SS-VRPTW-CR introduced in Saint-Guillain et al. (2017). Like the SS-VRP introduced by Bertsimas (1992), we search for optimal first stage routes for a fleet of vehicles to handle a set of stoch...

Validation is the assessment of the match between a model’s predictions and any empirical observations relevant to those predictions. This comparison is straightforward when the data and predictions are deterministic, but is complicated when either or both are expressed in terms of uncertain numbers (i.e., intervals, probability distributions, p-boxes, or more general imprecise probability stru...
