Approach to the Monitoring of Energy Consumption in Eco-grinder Based on ABC Optimization

This article is a part of the series dedicated to AI Methods Inspired by Nature and their implementation in the mechatronic systems. The Artificial Bee Colony (ABC) enables the optimization of the consumption of power supplied from photovoltaic cells. The paper includes a few implementations of ABC. Special emphasis was put on maintaining proper energetic balance, and on monitoring of power demand as well as energy sources used for the comminution. The ecological grinder was designed based on the autonomic unit. It can be called autonomous, because it does not need external control. The built-in computer system ensures monitoring and visualization of the current state of the energetic balance.

Optimization of Fuel Consumption in Firefighting Water Capsule Flights of a Helicopter

This article presents a possible use of ABC method for optimization of fuel consumption of helicopter which transport water capsule. There are lot of attibutes of flight e.g. the mass of the capsule, velocity, altitude, aerodynamic coefficients of the capsule, and horizontal and vertical winds. The presented method is focused on mentioned attributes. The problem is very important because helicopters are used in real hughe fire and it will be quite good if the fueal needed for this will be as low as possible. That is why authors presents theoretical models of flight of a bag filled with water which is then dropped from an aircraft moving horizontally. The resulet achived by numerical computations are later compared with the results measured for the trajectory of a capsule of water dropped from a helicopter. There ia also a discussion of the experimental and numerical results achieved in mentioned experiment.

CAD/CAE Applications in Mill’s Design and Investigation

CAD/CAE are crucial in supporting structural design shredders, as well as the management of the acquisition test data. These tools, but also the AI has been used to search for the best solution of shredder. Implementations of this method and verification of shredding on many edges improve operational performance. Selected results and analysis have been verified with the results of the laboratory tests.

Real-Time System of Delivering Water-Capsule for Firefighting

The alternative and efficient technique of large-scale fire extinguishment is the method of explosive-produced water aerosol. In this method the water capsule, which is source of aerosol, is delivered by the helicopter near the fire area and then is released and detonated. The efficiency of this technique depends on quality of control system - its determinism, speed of computation of the moment of capsule’s release and reliability of components. The article presents design assumptions, selection of the integration step size in numerical method, structure of the real-time system and practical verification of the system.
