Modelling of batch bioreactors
Mathematical models of fermentation processes are indispensable for designing bioreactors, simulation of their operation, optimization of fermentation processes, and design and synthesis of control systems for their control. The paper focuses on the determination of a dynamic mathematical model of the milk fermentation process taking place in a batch bioreactor.

On-line monitoring of hydraulic filter and machine condition
In addition to the hydraulic pump and actuator, which are the ever-present vital components of the hydraulic system, the hydraulic filter on the return line is also the ever-present, indispensable component of any hydraulic system.

Kamikaze – Spirit/Divine Wind (Shinpū Tokubetsu Kōgetai)
Kamikaze (divine wind or spirit wind) were Japanese pilots who in WWII made deliberate suicidal crashes into enemy ships. The pilot (kamikaze) had no means of getting out once the missile was fastened to the aircraft that would launch it.

Water-hydraulic endurance test of an oil-hydraulic proportional directional control valve
Hydraulic fluids made from fossil fuels are a major ecological burden despite their good corrosion and wear properties. Water seems to be the future of hydraulic fluids, but due to lack of interest and special equipment, it is still underestimated.

Mathematical Model to calculate the Volume of Hydraulic Accumulator
Hydraulic accumulators (HA) are installed in numerous HS mostly to add pressurized hydraulic liquid (HL) in HS to compensate the disproportionate consumption of some working hydraulic components…

Scientific Commentary of the Particulary Criminal Code – Penal Acts against the Safety of the Public Traffic
Slovenia has got the Scientif Commentary of the Particular Criminal Code – Penal Acts against the Safety of the Public Traffic.

Determination of static sensitivities of fast-response pressure measurement systems
This paper presents a dynamic and quasi-static method for determination of static sensitivity of fast-response piezoelectric pressure measurement system. In order to establish SI traceability for time-varying pressure measurements…

Hydraulic Accumulator
Hydraulic accumulators are installed in numerous HS for various tasks, but mostly to add pressurized hydraulic liquid (HL) in HS. In some HS, a large, far above-average amount of pressurized liquid HL is required…

Human-Machine Interaction in Industry 4.0 and Beyond
Manufacturing represents around 15% of the value-added and total employment in Europe. It is also of great importance to the EU and its R&D efforts, to which almost two thirds is contributed by manufacturing.

Advanced data-based methods for fault detection in HVAC systems
Fault detection in industrial systems plays a crucial part of the correct and optimal operation of the different processes. The possible faults could be of different types and natures and occur on different components of the process.
