Design of a Segmentation and Classification System for Seed Detection Based on Pixel Intensity Thresholds and Convolutional Neural Networks
(2023)
Due to the computational power and memory of modern computers, computer vision techniques and neural networks can be used to develop a visual inspection system of agricultural products to satisfy product quality requirements. ...
Manufacturing and Measuring Techniques for Graphene-Silicone-Based Strain Sensors
(2023)
The development of techniques for synthesizing graphene and its derivatives, as well as currently available nanocomposite fabrication techniques, coupled with the diverse applications of strain and pressure sensors, has ...
Measuring material thickness changes through tri-aperture digital speckle pattern interferometry
(2023)
A configuration for the measurement of thickness changes in materials through one-shot digital speckle pattern interferometry (DSPI) was developed. The phase maps calculation was made by adding carrier fringes by the ...
Mathematic Modelling of a Reversible Hydropower System: Dynamic Effects in Turbine Mode
(2023)
Over the past few years, there has been significant interest in the importance of reversible hydro-pumping systems due to their favorable flexibility and economic and environmental characteristics. When designing reversible ...
Loneliness and vertical and horizontal collectivism and individualism: A multinational study
(2023)
This paper investigates how horizontal and vertical individualism and collectivism predict self-report loneliness in addition to the variance accounted for by age and sex in 28 countries (N = 8,345). Horizontal and vertical ...
Application of the Generalized Normal Distribution Optimization Algorithm to the Optimal Selection of Conductors in Three-Phase Asymmetric Distribution Networks
(2023)
This article addresses the problem of the optimal selection of conductors in asymmetric three-phase distribution networks from a combinatorial optimization perspective, where the problem is represented by a mixed-integer ...
Corneal endothelium assessment in specular microscopy images with Fuchs’ dystrophy via deep regression of signed distance maps
(2023)
Specular microscopy assessment of the human corneal endothelium (CE) in Fuchs’ dystrophy is challenging due to the presence of dark image regions called guttae. This paper proposes a UNet-based segmentation approach that ...
Applying the Crow Search Algorithm for the Optimal Integration of PV Generation Units in DC Networks
(2023)
This paper presents an efficient master–slave methodology to solve the problem of integrating photovoltaic (PV) generators into DC grids for a planning period of 20 years. The problem is mathematically formulated as ...
Identifying, Quantifying, and Recovering a Sorbitol-Type Petrochemical Additive in Industrial Wastewater and Its Subsequent Application in a Polymeric Matrix as a Nucleating Agent
(2023)
Currently, polypropylene (PP) is highlighted using sorbitol-based clarifying agents since these agents are high quality, low cost, and work as a barrier against moisture, which makes PP ideal for packaging food, beverages, ...
Optimal Phase-Balancing in Three-Phase Distribution Networks Considering Shunt Reactive Power Compensation with Fixed-Step Capacitor Banks
(2023)
The black hole optimization (BHO) method is applied in this research to solve the problem of the optimal reactive power compensation with fixed-step capacitor banks in three-phase networks considering the phase-balancing ...
