	Quality of surface produced by modulated jet Sitek, Libor ; Foldyna, Josef ; Jekl, Pavel ; Nováková, Daria Machined surfaces can generally be characterized by surface texture or geometric parameters, which may also reflect subsurface features. The paper deals with the determination of quality of bottom surface of the kerf created by modulated jet. The quality of bottom surface of the kerf was examined and compared to that created by continuous jet at the same operating parameters. Shapes and sizes of kerfs created both by pulsed and continuous jets were also studied. Detailed record
	Disintegration of concrete and rocks by modulated water jet: laboratory experiments Sitek, Libor ; Foldyna, Josef ; Ščučka, Jiří Problem of preparation of concrete and rock surfaces before repair using modulated water jet is a subject of the paper. Selected results of laboratory tests of disintegration of various types of concrete as well as rocks are presented and compared with results of concrete and rock disintegration by means of continuous water jet under the same operating conditions. Detailed record
	Modulation of waterjet by ultrasonic: Measurement of dynamic pressure and force effects Foldyna, Josef ; Sitek, Libor ; Jekl, Pavel ; Nováková, Daria Series of measurement of a dynamic pressure inside the ultrasonic nozzle under its various configurations were performed within the framework of research focused on modulation of waterjet by ultrasonic. Results of measurement are compared and discussed in the paper. Detailed record
	Utilisation of modulated water jets for cleaning and removal of surface layers Sitek, Libor ; Foldyna, Josef ; Nováková, Daria A problem of cleaning and removing of surface layers is a subject of the paper. The review of traditional cleaning methods is accompanied with section dealing with cleaning by high speed water jets, and, in particular, by ultrasonic modulated jets. Advantage of using such the jets are presented from booth economical and ecological points of view. Detailed record
	Measurement of force effects of modulated jet Foldyna, Josef ; Sitek, Libor ; Jekl, Pavel ; Nováková, Daria Results obtained in measurement of force effects of water jets modulated by ultrasonic vibration of a tip situated inside the nozzle are presented. Both method of modulation of the jet and method of measurement of force effects of the jet are briefly described. Potential of the measurement of force of modulated jets in determination of optimum configuration of the ultrasonic nozzle is discussed. Detailed record
	Comparison of various types of nozzles for high-speed water jet generation Sitek, Libor ; Foldyna, Josef ; Nováková, Daria In the paper, three different types of nozzles for high-speed water jet generation are compared. The original methodology is used for comparison that is based on combination of three independent groups of measurement. Detailed record
