Generalized linear‐constrained optimal power flow for distribution networks

open access: yesIET Generation, Transmission & Distribution, 2023
Optimal power flow (OPF) plays an important role in the secure and economical operation of the distribution network. This paper proposes a novel generalized linear‐constrained optimal power flow (GLOPF) model for both radial and mesh distribution ...

Linear stability analysis of blood flow in small vessels

open access: yesApplications in Engineering Science, 2020
We investigate the linear stability of unidirectional Poiseuille flow of blood modeling the fluid as a spatially inhomogeneous fluid in which viscosity depends on the red blood cell concentration (RBCs).

Multi-Angle Liquid Flow Measurement Using Ultrasonic Linear Array Transducer

open access: yesSensors, 2020
Most ultrasonic flowmeters utilize several wedge sensors for transmission and reception. Thus, the location and alignment of the sensors are critical factors that determine the performance of the ultrasonic flowmeter.

Linear and non-linear flow mode in Pb–Pb collisions at sNN=2.76 TeV

open access: yesPhysics Letters B, 2017
The second and the third order anisotropic flow, V2 and V3, are mostly determined by the corresponding initial spatial anisotropy coefficients, ε2 and ε3, in the initial density distribution.

Linear Flows on $\kappa $-Solenoids

open access: yesTopology and its Applications, 1999
Linear flows on inverse limits of tori are defined and it is shown that two linear flows on an inverse limit of tori are equivalent if and only if there is an automorphism of the inverse limit generating the equivalence.

Linear Stability of a Combined Convective Flow in an Annulus

open access: yesFluids, 2023
Linear stability analysis of a combined convective flow in an annulus is performed in the paper. The base flow is generated by two factors: (a) different constant wall temperatures and (b) heat release as a result of a chemical reaction that takes place ...

Bench scale laboratory tests to analyze non-linear flow in fractured media [PDF]

open access: yesHydrology and Earth System Sciences, 2012
The knowledge of flow phenomena in fractured rocks is very important for groundwater resources management in hydrogeological engineering. <br><br> A critical emerging issue for fractured aquifers is the validity of the Darcian-type "local ...

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 ...
