Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinder who grinds discarded plastics to granules which later can be reused when pressure molding plastics. The company wanted help in developing a new, or alternatively extending their previous, measurement equipment. The old equipment was hard to use, required changes in the code for different measurement scenarios and had a limited array of measuring quantities. Rapid had an idea of a similar concept only with a greater number of input ports, better range of applicable sensors and an advanced yet easy to use interface. The system is supposed to be placed at Rapid's test department where it will be used as a tool for finding faults and provide data which can be used for further development of the granulators. The project's members accepted the task and immediately began searching for suitable components for the system. After the search was completed a list of costs, limitations, sensors, I/O's and development environment was presented to Rapid's staff. In consultation with their staff some components were ordered, and the development team was asked to keep the system open for future upgrades. Some difficulties arose when shipment times which were promised to four weeks actually took six weeks. In the mean time the chassis of the measurement cart were constructed. One working day was spent at Rapid's workshop to assemble the cabinets with the rack and the wheelbase. LabVIEW arrived first and quite a lot of time was spent on getting acquainted to the program. When the parcel containing all the electronic material arrived, everything was mounted and the final stage involving programming and testing of the sensors and the measurement cart could commence. Tests with accelerometer, strain gauges and PT-100 showed that the measurement unit worked. The sampled data acquired from the cart were compared to measurements made with calibrated instruments.

Thesis (doctoral)--Lund, 1981.

This doctoral thesis deals with the study of electro-hydrodynamics in the area of numerical modelling of biomechanical systems, concretely in the method of bioimpedance plethysmography. Solving tasks of pulsatile blood flow in the elastic vessel wall is currently one of the most complicated problem in mechanics and biomechanics due to the interaction of two continua on the common boundary. The whole system is additionally loaded by diagnostic electric current. This doctoral thesis was created in cooperation with the Institute of Scientific Instruments of the CAS, v. v. i. Brno with the team engaged in medical signals (the leader Ing. Pavel Jurák, CSc.). Experimental measurements were made independently in the St. Anne's University Hospital Brno in the International Clinical Research Center ICRC and in the Mayo Clinic USA.

The aim of the thesis "Evaluation of qualitative parameters of rams ejaculates" was to compare techniques of ejaculate collection of rams of combined breed. The sampling technique for the artificial vagina was compared to that of the electro-ejaculator. The quantitative and qualitative indicators of ejaculates of rams were evaluated in the thesis. The parameters evaluated were: ejaculate volume, sperm movement, sperm initial aktivity, sperm concentration in ejaculate and sperm morphology. Samples were taken at four days. A total of 24 samples were obtained from 10 rams of the combined breed, of which 12 were sampled by artificial vagina sampling by stimulation with fixed sheep and 12 samples by electro-ejaculator. The electro-ejaculator collection technique was found to have lower sperm concentration (P≤0.01) and lower initial activity (P≤0.05) compared to the artificial vagina collection technique. The difference in ejaculate volume and sperm movement in the compared methods was not statistically demonstrated. No significant differences between sperm collection techniques in sperm abnormalities were observed or statistically demonstrated. The results of the diploma thesis showed that the better technique of ejaculate collection is taking on the artificial vagina, because it leads to higher initial activity of sperm (P≤0.05) and higher concentration of sperm (P≤0.01), which can be used mainly in the preparation of insemination doses.
