Optimal semi‐dynamic traffic and power flow assignment of coupled transportation and power distribution systems for electric vehicles

IET Electrical Systems in Transportation, 2023
As the most promising alternative to internal combustion engines (ICEs), electric vehicles (EVs) have an excellent development outlook. The charging route scheduling of EVs can simultaneously affect traffic congestion in the transportation network (TN ...

Error analysis and improvement framework for linear power flow models under wide operating conditions

Frontiers in Energy Research
Linear power flow models are typically derived through a Taylor expansion of specific state variable functions, serving as numerical approximations valid within a finite neighborhood of an initial operating point.

Effective rheology of immiscible two-phase flow in porous media consisting of random mixtures of grains having two types of wetting properties

Frontiers in Physics, 2023
We consider the effective rheology of immiscible two-phase flow in porous media consisting of random mixtures of two types of grains having different wetting properties using a dynamic pore network model under steady-state flow conditions. Two immiscible

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

A Novel Linear Optimal Power Flow Model for Three-Phase Electrical Distribution Systems [PDF]

2020 International Conference on Smart Energy Systems and Technologies (SEST), 2020
This paper presents a new linear optimal power flow model for three-phase unbalanced electrical distribution systems considering binary variables. The proposed formulation is a mixed-integer linear programming problem, aiming at minimizing the operational costs of the network while guaranteeing operational constraints. Two new linearizations for branch

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

A Physics-based and Data-driven Linear Three-Phase Power Flow Model for Distribution Power Systems

CoRR, 2021
Distribution power systems (DPSs) are mostly unbalanced, and their loads may have notable static voltage characteristics (ZIP loads). Hence, despite abundant papers on linear single-phase power flow models, it is still necessary to study linear three-phase distribution power flow models.
