An Approximate Model for Determining the Resistance of a Hemispherical Ground Electrode Placed on a Non-homogeneous Truncated Cone
(2023)In this paper we present an approximate analytically oriented approach for determining the resistance of a hemi-spherically-shaped ground electrode placed on the top of a mountain. The mountain is modelled as a non-homogeneous ... -
Computer Vision-based Fire Detection using Enhanced Chromatic Segmentation and Optical Flow Model
(2023)Forests are one of the most important natural resources in the world. However, the occurrence of forest fires will burn plants and kill animals. Emergency incidents and events of fires can be dangerous and require quick ... -
Controlling the Spindle Speed when Milling Free-Form Surfaces using Ball-End Milling Cutter
(2023)Ball-end tools are widely used in industries such as die/mould, automobile, and the aerospace industry. These cutters are specially used when finishing complex three- dimensional sculptured surfaces. However, when using ... -
Detecting the Absence of Lung Sliding in Ultrasound Videos Using 3D Convolutional Neural Networks

On the Use of Quaternions, in the Translated Reference Frame Formalism
(2023)The approaches dedicated to the geometric model of the object, in the object- oriented modeling framework, specific to robots, are focused on the computation of the position of the elements, relative to a global reference ... -
Optimal Fuzzy Controller, using a Genetic Algorithm for a Ball on Wheel System
(2023)The process of building a fuzzy controller for the Ball on Wheel problem raised an issue with the optimization of the controller parameters. For non-linear systems the parameter values of the controller are based on a ... -
Petri Net-based S3PR Models of Automated Manufacturing Systems with Resources and Their Deadlock Prevention
(2023)Correct allocation of resources in Automated Manufacturing Systems (AMS) is very important, especially in order to avoid deadlocks and their consequences. Petri Nets (PN) are frequently used for modeling AMS. S3PR (Systems ... -
Pneumatic Piston Control Modelling and Optimization
(2023)Piston control can be used for position, speed, acceleration, and force control. The main difference between pneumatic, and hydraulic cylinders is that the hydraulic control uses fluid instead of gas, and fluids are ... -
