Wind Energy, Volume 26, Issue 1, Page 76-97, January 2023., 2023 Abstract This study investigates the implementation of the vortex particle method (VPM) with the goal of efficiently and accurately estimating the power performances and flow characteristics for a Savonius rotor. The accuracy and efficiency of simulation methods are critical for the reliable design of Savonius rotors.

Вестник Дагестанского государственного технического университета: Технические науки, 2017 Objectives. The aim of present work was to carry out mathematical modelling of heat transfer with symmetrical heating in flat channels and round pipes with rough walls.Methods. The calculation was carried out using the L'Hôpital-Bernoulli's method.

Wind Energy, Volume 26, Issue 1, Page 98-125, January 2023., 2023 Abstract Growing horizontal axis wind turbines are increasingly exposed to significant sources of unsteadiness, such as tower shadowing, yawed or waked conditions and environmental effects. Due to increased dimensions, the use of steady tabulated airfoil coefficients to determine the airloads along long blades can be questioned in those numerical fluid

Large deviations for stochastic flows of diffeomorphisms [PDF]
Bernoulli 2010, Vol. 16, No. 1, 234-257, 2010 A large deviation principle is established for a general class of stochastic flows in the small noise limit. This result is then applied to a Bayesian formulation of an image matching problem, and an approximate maximum likelihood property is shown for the solution of an optimization problem involving the large deviations rate function.

Attention assessment based on multi‐view classroom behaviour recognition
IET Computer Vision, EarlyView., 2022 Abstract In recent years, artificial intelligence has been applied in many fields, and education has attracted more and more attention. More and more behaviour detection and recognition algorithms are applied in the field of education. Students' attention in class is the key to improving the quality of teaching, and classroom behavior is a direct ...

On fair pricing of emission-related derivatives [PDF]
Bernoulli 2010, Vol. 16, No. 4, 1240-1261, 2010 Tackling climate change is at the top of many agendas. In this context, emission trading schemes are considered as promising tools. The regulatory framework for an emission trading scheme introduces a market for emission allowances and creates a need for risk management by appropriate financial contracts.

On the form of the large deviation rate function for the empirical measures of weakly interacting systems [PDF]
Bernoulli 2014, Vol. 20, No. 4, 1765-1801, 2012 A basic result of large deviations theory is Sanov's theorem, which states that the sequence of empirical measures of independent and identically distributed samples satisfies the large deviation principle with rate function given by relative entropy with respect to the common distribution. Large deviation principles for the empirical measures are also

Diversity of global fisheries governance: Types and contexts
Fish and Fisheries, Volume 24, Issue 1, Page 111-125, January 2023., 2023 Abstract Fisheries governance systems designed to regulate fishing are often described as being highly diverse across countries. However, there is little systematic work that directly examines and describes the (dis)similarities across such systems, and how socio‐political and economic contexts drive such variation at a global scale.

Waltham, C. E., Bendall, S., Kotlicki, A., "Bernoulli Levitation",
Am. J. Phys. 71 (2003) 176-179, 2002 "Bernoulli" levitation is the basis of many popular counter-intuitive physics demonstrations. However, few of these lend themselves to a quantitative description without recourse to computational fluid dynamics. Levitation of a flat plate is the exception, and we present here a straightforward analysis which illustrates several principles of fluid ...
