Increase of the Ship Fuel Consumption Due to Added Resistance in Waves

open access: yesJournal of Sustainable Development of Energy, Water and Environment Systems, 2017
Added resistance in waves is the second-order steady force dependant on the ship motions. It significantly affects ship operability and cause speed loss. Therefore the required power and fuel consumption of a ship advancing in a seaway are increasing. In

The impact of the Dirichlet boundary conditions on the convergence of the discretized system of nonlinear equations for potential problems

open access: yesComputer Assisted Methods in Engineering and Science, 2017
The purpose of this paper is the analysis of numerical approaches obtained by describing the Dirichlet boundary conditions on different connected components of the computational domain boundary for potential flow, provided that the domain is a rectangle.

A Numerical Study on Hydrodynamic Performance of an Inclined OWC Wave Energy Converter with Nonlinear Turbine–Chamber Interaction Based on 3D Potential Flow

open access: yesJournal of Marine Science and Engineering, 2020
In this study, a time-domain numerical method based on three-dimensional potential flow was developed to analyze the hydrodynamic characteristics of an inclined oscillating-water-column (OWC) wave energy converter (WEC).

Analytical and Numerical Model of Sloshing in a Rectangular Tank Subjected to a Braking

open access: yesMathematics, 2023
This paper examines the movement of waves that occur in a fuel tank—both with and without a wave breaker—when a car is travelling at a constant speed and then suddenly brakes. This phenomenon is known as slosh noise, and the paper presents an analysis of

Vortex Structure and Kinematics of Encased Axial Turbomachines

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2018
This paper models the kinematics of the vortex system of an encased axial turbomachine at part load and overload applying analytical methods. Thus far, the influence of the casing and the tip clearance on the kinematics have been solved separately.

Unsteady Lift Prediction with a Higher-Order Potential Flow Method

open access: yesAerospace, 2020
An unsteady formulation of the Kutta–Joukowski theorem has been used with a higher-order potential flow method for the prediction of three-dimensional unsteady lift.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Renormalization group flow of the Higgs potential [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
We summarize results for local and global properties of the effective potential for the Higgs boson obtained from the functional renormalization group, which allows one to describe the effective potential as a function of both scalar field amplitude and renormalization group scale.

Numerical Analysis for Hydrodynamic Performance of OWC Devices with Multiple Chambers in Waves

open access: yes한국해양공학회지, 2022
In recent years, various studies have been conducted on oscillating-water-column-type wave energy converters (OWC-WECs) with multiple chambers with the objective of efficiently utilizing the limited space of offshore/onshore structures.

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.
