Reliability, along with energy efficiency, is an important characteristic of pump units in various applications. In practical applications, it to strike a balance between reliability and efficiency. These indicators strongly depend on the applied control method unit. This study analyzes trade-off for regulating system three parallel pumps equipped only one frequency converter (multi-pump single...
The paper discusses monolithic approach against microkernel approach both used in operating systems. The paper presents the most critical features of operating systems concerning system architecture, communication model, and priority in processes, memory management and handling of any arrived exceptions as well as interrupts. The interrupt is a crucial factor for real time operating systems (RT...
Determining the Hydro-acoustic Characteristics of the Ship Propeller in Uniform and Non-uniform Flow
This research has been carried out to determine the marine propeller hydro-acoustic characteristics by Reynolds-Averaged Navier-Stokes (RANS) solver in both uniform and non-uniform wake flow at different operating conditions Wake flow can cause changes in pressure fluctuation and gas effect on propeller noise spectrum. Noise is generated by the induced trailing vortex wake and induced pressure ...
Background Acupuncture is a relatively safe, commonly used "alternative" medical treatment for various symptoms. However, adverse effects can occur, including trauma, pneumothorax, and central-nervous-system injury. Our objective was to develop a reliable and practical procedure for ultrasound imaging of acupuncture points to improve safety during needling, and to acquire ultrasound images of s...
In the case of widely-uncertain non-linear system control design, it was very difficult to design a single controller to overcome control design specifications in all of its dynamical characteristics uncertainties. To resolve these problems, a new design method of robust fuzzy control proposed. The solution offered was by creating multiple soft-switching with Takagi-Sugeno fuzzy model for optim...
