Variable-fidelity surrogate modeling offers an efficient way to generate aerodynamic data for aero-loads prediction based on a set of CFD methods with varying degree of fidelity and computational expense. In this paper, new algorithms, such as a Gradient-Enhanced Kriging method (direct GEK) and a generalized hybrid bridge function, have been developed to improve the efficiency and accuracy of t...

This paper presents a short overview of the state of the art and future challenges of the use of full-field measurements and inverse procedures to identify the constitutive mechanical parameters of a wide range of materials. It concentrates on the so-called Virtual Fields Method (VFM) which is a tool fully dedicated to the processing of full-field measurements. Some of the future challenges are...

Purpose While empirical studies establish the importance of procurement planning in achieving value for money (VfM) procurement, there is scant evidence demonstrating a link between and regulatory compliance, thus VfM. As result, this study examined how compliance can be applied when practitioners Tanzania seek to maximize VfM through planning. Design/methodology/approach A cross-sectional rese...

The vortex force map (VFM) method is a promising low-cost technique for predicting unsteady aerodynamic load from the vorticity field. Developed under potential flow assumption and applied to high-resolution computational fluid dynamics (CFD) data, original VFM needs be further explored viscous flows, especially at low Reynolds numbers with incomplete knowledge of data. In this paper, extended ...

Vection is an illusory perception of self-motion that can occur when visual motion fills the majority of the visual field. This study examines the effect of the duration of visual field movement (VFM) on the perceived strength of self-motion using an inertial nulling (IN) and a magnitude estimation technique based on the certainty that motion occurred (certainty estimation, CE). These technique...

UNLABELLED BACKGROUND Deciding which health technologies to fund involves confronting some of the most difficult choices in medicine. As for other countries, the Israeli health system is faced each year with having to make these difficult decisions. The Public National Advisory Committee, known as 'the Basket Committee', selects new technologies for the basic list of health care that all Isr...

A virtual flow meter (VFM) enables continuous prediction of rates in petroleum production systems. The predicted may aid the daily control and optimization a asset. Gray-box modeling is an approach that combines mechanistic data-driven modeling. objective to create computationally feasible VFM for use real-time applications, with high accuracy scientifically consistent behavior. This article in...

Abstract The study on public mass transportation in Batam City was started 2010 by BP Batam. is still a long polemic due to problems arise technical and non-technical aspects, such as limited funding capacity of local government. Therefore, the government wants involve private sectors development plan. This aims analyse selection Public Private Partnership (PPP) scheme using value for money (Vf...
