Advanced control strategies, together with state-estimation methods, are frequently applied to nonlinear and complex systems. It is crucial understand which of these the most efficient methods for best use approaches in a chemical process. In current work, model predictive (NMPC) were developed that considered three numerical methods: single shooting (SS), multiple (MS), orthogonal collocation ...

ABSTRACT We present a perturbative treatment of non-linear galaxy clustering in the context cubic Galileon modified gravity model, terms second-order Lagrangian Perturbation theory and an extension ellipsoidal collapse that includes Vainshtein screening. numerically implement such prescriptions approximate pinocchio code, use it to generate realizations matter density field halo catalogues with...

Nickle is a vaguely C-like programming language for numerical applications, useful both as a desk calculator and as a prototyping and implementation language for numerical and semi-numerical algorithms. Nickle abstracts a number of useful features from a wide variety of other programming languages, particularly functional languages. Nickle’s design principles and implementation pragmatics mesh ...

Digital stochastic measurement method implementation is considered from signal stationarity point of view. It is shown how conceptual block diagram for digital stochastic measurement of one Fourier coefficient can be simplified and used for developing conceptual block diagram for measuring predefined set of signal harmonics. Hardware of digital stochastic measurement block interfaced to recordi...

Analytical expressions correlating the volumetric flow rate to the inlet and outlet pressures are derived for the time-independent flow of Newtonian fluids in cylindrically-shaped elastic tubes using a one-dimensional Navier-Stokes flow model with two pressure-area constitutive relations. These expressions for elastic tubes are the equivalent of Poiseuille and Poiseuille-type expressions for ri...

Computer egress simulation has potential to be used in large scale incidents to provide live advice toincident commanders. While there are many considerations which must be taken into account whenapplying such models to live incidents, one of the first concerns the computational speed of simulations.No matter how important the insight provided by the simulation, numerical hindsight ...

A practical three-dimensional shape optimization for aerodynamic design of a transonic wing has been performed using Evolutionary Algorithms (EAs). Because EAs coupled with aerodynamic function evaluations require enormous computational time, Numerical Wind Tunnel (NWT) located at National Aerospace Laboratory in Japan has been utilized based on the simple master-slave concept. Parallel process...

In the paper a recent enhancement to the open source package SfePy (Simple Finite Elements in Python, http://sfepy.org) is introduced, namely the addition of another numerical discretization scheme, the isogeometric analysis, to the original implementation based on the nowadays standard and wellestablished numerical solution technique, the finite element method. The isogeometric removes the nee...

BACKGROUND In most countries, genetic carrier screening is neither offered, nor embedded in mainstream healthcare. Technological developments have triggered a two-fold transition in carrier screening: the expansion from screening one single disorder to many disorders simultaneously, and offering screening universally, regardless of ancestry. This study aims to identify general and population-sp...
