most common hypotheses of seizure initiation are increased neural excitation, decreased inhibition or both. but, the conditions that lead to these activation states not to be clear yet. recent studies challenge traditional concepts and indicate new evidence that a key epileptogenic process may actually begin in the blood vessel. seizures could be initiate by a variety of insults to the brain, s...

the paper presents the results of an investigation on the acoustic performance of vertical profile parallel barriers with quadratic residue diffuser tops and faces. a 2d boundary element method (bem) was used to predict the barrier insertion loss. the results of rigid and with absorptive coverage were also calculated for comparisons. using qrd on the top surface and faces of all vertical profil...

In this paper, we consider an interval coverage problem. We are given n intervals of the same length on a line L and a line segment B on L. Each interval has a nonnegative weight. The goal is to move the intervals along L such that every point of B is covered by at least one interval and the maximum moving cost of all intervals is minimized, where the moving cost of each interval is its moving ...

In this paper, a study on the characteristics and the reduction methods of ground vibration due to the tilting train travelling in the conventional line is carried out. The load transmitted into the ground is computed considering the interaction between the tilting car and the line. This load is then applied in the numerical model for the analysis of ground vibration due to the travelling tilti...

In this article, we propose an extension of the multi-Weber facility location problem with rectilinear-distance in presence passages over a non-horizontal line barrier. For single-facility case, develop exact heuristic based on divide-and-conquer approach that outperforms alternative heuristics available literature. The multiple facilities case is solved by means application alternate-location-...

Here we present a primal-dual interior point multidimensional filter line search method for nonlinear programming. The filter relies on a multidimensional feasibility measure enforcing every constraint violation to zero. To prevent convergence to feasible nonoptimal points a sufficient reduction criterion is also imposed on the barrier function. The evaluation of the method is until now made on...
