Over the last few years, the problem of voltage stability has received a lot of attraction from the power system community. This type of stability is now a major concern for utilities in both planning and operating conditions. Both static and dynamic aspects of the problem have been discussed and investigated by the researchers. The present paper concentrates on a Voltage Stability Analysis fun...

BACKGROUND Intraoperative bacterial contamination is a major risk factor for postoperative wound infections. This study investigated the influence of type of ventilation system on intraoperative airborne bacterial burden before and after installation of unidirectional displacement air flow systems. MATERIAL AND METHODS We microbiologically monitored 1286 surgeries performed by a single surgic...

Fuzzy control is one of the most important parts of fuzzy theory for which several approaches exist. Mamdani uses $alpha$-cuts and builds the union of the membership functions which is called the aggregated consequence function. The resulting function is the starting point of the defuzzification process. In this article, we define a more natural way to calculate the aggregated consequence funct...

The data revolution is fueled by advances in several areas, including databases, high-performance computer architecture, and machine learning. Although timely, there is a void of solutions that brings these disjoint directions together. This paper sets out to be the initial step towards such a union. The aim is to devise a solution for the in-Database Acceleration of Advanced Analytics (DAnA). ...

Abstract We present d3p , a software package designed to help fielding runtime efficient widely-applicable Bayesian inference under differential privacy guarantees. achieves general applicability wide range of probabilistic modelling problems by implementing the differentially private variational algorithm, allowing users fit any parametric model with differentiable density function. adopts pro...

The tool VEqMon2D provides a framework to generate analytical expressions of equations motion 2D vehicle models in Matlab. Such are mostly used studies that focus on the infrastructure (pavement, railway tracks, bridges) and loaded by traversing traffic. main outcome is Matlab function matrix form. user has flexibility define model with multiple bodies, articulations, axle configurations. Subse...

Network slicing is one of the most important features in 5G which enables a large variety services with diverse performance requirements by network virtualization. Traditionally, can be viewed as one-size-fits-all slice and its are bundled proprietary hardware supported telecom equipment providers. Now virtualization technology 5G, open networking software deployed flexibly on commodity to offe...

In this paper, a computational intelligence method is used for the solution of fractional optimal control problems (FOCP)'s with equality and inequality constraints. According to the Ponteryagin minimum principle (PMP) for FOCP with fractional derivative in the Riemann- Liouville sense and by constructing a suitable error function, we define an unconstrained minimization problem. In the optimiz...
