On the Concept of Model in Physics

The Educational Review, USA, 2023
The concept of model is the basis for theoretical and experimental research in physics. A model is defined as an application of physical theories to the description of a physical system. As a premise to the introduction of models, physical theories are defined as mathematical frameworks with a hypothetical-deductive structure, provided with a mapping ...

Enhanced single-diode model for improved accuracy in photovoltaic cell characterization

e-Prime: Advances in Electrical Engineering, Electronics and Energy
The single-diode model (SDM) is widely used to simulate the behavior of photovoltaic (PV) cells. In the conventional approach, these models, referred to as voltage-independent SDM (SDMvi), assume that their parameters remain constant regardless of the PV

Experimental and Finite Element-Based Investigation on Lateral Behaviors of a Novel Hybrid Monopile

Energies, 2022
A monopile is the most conventional structure foundation for offshore wind turbines (OWTs) in the world. However, the Korean offshore wind industry has mostly been using the jacket type of foundation. The main reason for the current situation in Korea is

A Model for Physical Nucleon [PDF]

Progress of Theoretical Physics, 1962
The anomalous magnetic moment of nucleon is investigated by taking the possible ex­ citations of the nucleon core or the cloud pions into account. For the sake of definiteness and simplicity two assumptions are made: 1) the physical nucleon is composed of the static core accompanied by one or no cloud particle, 2) the virtual excitations can be treated

Development of a model ensemble to predict Peary caribou populations in the Canadian Arctic Archipelago

Ecosphere, 2019
In the field of biological conservation, mathematical modeling has been an indispensable tool to advance our understanding of population dynamics. Modeling rare and endangered species with complex ecophysiological tools can be challenging due to the ...

The Influence of Parameters of Argon Purging Process Through Ladle on the Phenomena Occuring in the Area of Phase Distributions: Liquid Steel-Slag [PDF]

Archives of Metallurgy and Materials, 2019
Purging the liquid steel with inert gases is a commonly used treatment in secondary metallurgy. The main purposes for which this method is used are: homogenization of liquid steel in the entire volume of the ladle, improvement of mixing conditions ...

Increased Risk of Sarcomas in Children With Congenital Anomalies: Findings From the Genetic Overlap Between Anomalies and Cancer in Kids (GOBACK) Registry Linkage Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.
