Optimal Power Dispatch of DGs in Radial and Mesh AC Grids: A Hybrid Solution Methodology between the Salps Swarm Algorithm and Successive Approximation Power Flow Method
(2022)
In this paper, we address the problem of the optimal power dispatch of Distributed Generators (DGs) in Alternating Current (AC) networks, better known as the Optimal Power Flow (OPF) problem. We used, as the objective ...
Equivalence of categories of simple Lie algebras in positive characteristic
(2022-07-18)
In this paper we first study some properties of the finite-dimensional simple restricted Lie algebras. In the literature is found a one-to-one correspondence between them and finite-dimensional simple Lie algebras over a ...
Polarization study in Newtonian telescope components for depolarization parameter correction in atmospheric LiDAR
(2023-06-12)
In the present work, an experimental system is implemented, and a theoretical model is built that allows quanti fying atmospheric depolarization in the city of Santiago de Cali, Colombia. The experimental setup uses a ...
In-situ imaging and electrochemical monitoring of damaged thermal spray aluminium coating in synthetic seawater
(2023-07-14)
This paper presents the results of a study that combined electrochemical monitoring with in-situ imaging of Thermal Spray Aluminium (TSA) coating in synthetic seawater at room temperature in quiescent condition. The coatings ...
Analyzing traffic conflicts and the behavior of motorcyclists at unsignalized three-legged and four-legged intersections in Cartagena, Colombia
(2023-07-14)
Introduction: The global motorcycle market has grown significantly, with over 770 million vehicles estimated to be in use worldwide. Motorcycle-related road traffic deaths in low and middle-income countries (LMICs) like ...
Comparing Journalistic Role Performance Across Thematic Beats: A 37-Country Study
(2023-06-29)
Studies suggest that, at the routine level, news beats function as unique “micro-cultures.” Exploring this “particularist” approach in news content, we compare how the interventionist, watchdog, loyal, service, infotainment, ...
Statistical Approach for Computing Base Flow Rates in Gaged Rivers and Hydropower Effect Analysis
(2023-06-27)
The calculation of base flow rates in rivers is complex since hydrogeological and hydrological
studies should be performed. The estimation of base flow rates in storm hydrograph associated to
various return periods is ...
Different Experimental and Numerical Models to Analyse Emptying Processes in Pressurised Pipes with Trapped Air
(2023-06-29)
In hydraulic engineering, some researchers have developed different mathematical and numerical tools for a better understanding of the physical interaction between water flow in pipes with trapped air during emptying ...
Effect of pyrolysis, impregnation, and calcination conditions on the physicochemical properties of TiO2/Biochar composites intended for photocatalytic applications
(2023-06-02)
Biochars are outstanding materials obtained from the pyrolysis of biomass, possessing unique physicochemical properties that are attractive for many environmental applications, including photocatalysis. In this work, we ...
Applying a Green Solvent with Microwave, Ultrasound, and Soxhlet Extraction Techniques to Quantify the Slip Additive Cis-1,3-docosenamide and Nine Oxidative Degradation Byproducts in Polypropylene Samples
(2023-08-18)
Erucamide is used as an important slip agent for polymers. However, erucamide can
degrade during processing and long-term storage, forming various oxidation products. These degra dation products can affect the recovery ...
