Pavel Navrátil, Jaroslav Balátě & Tomas Sysala Tomas Bata University in Zlín, Faculty of Applied Informatics Nad Stráněmi 4511, 760 05 Zlín Czech Republic ABSTRACT This paper describes one of possible way to control of MIMO control loop with utilisation of the so called binding members and correction members. The designed method combinations classical way to ensure of autonomy of control loop v...

Concept of Safe diagram was introduced 30 years ago (Singh and Schiffer, 1982) for the analysis of the vibration characteristics of packeted bladed disc for steam turbines. A detailed description of Safe diagram for steam turbine blades was presented 25 years ago in the 17 th Turbo Symposium (Singh et. el, 1988). Since that time it has found application in the design and failure analysis of man...

A steam turbine, heart of all refineries. This work presents the mathematical modelling of the steam turbine unit in isolated operating condition, based on the continuity equation including servomotor for actuation purpose. Steam turbine should run at a constant speed for its safe operation and frequency stability. Adaptation of different controller like Feedback, PI, PID using certain adaptati...

This article deals with the development of sawmilling over the area of the Czech Republic from the invention of the waterwheel drive until the present day. This survey is based on the writings of various Czech authors who were engaged, or still are, in this subject. The two most common types of machines in water-driven sawmills were both used at that time: the single-blade vertical frame saw an...

In this paper, a headspace solid-phase microextraction (HS-SPME) method was applied to analyse the volatile compounds in a traditional Chinese medicine (TCM), Rhioxma Curcumae Aeruginosae. SPME parameters such as fibers, extraction temperature, extraction time and desorption time were investigated. Thirty-five volatile compounds were separated and identified. Relative standard deviations (RSDs)...

We are developing a novel high-efficiency, high-temperature steam electrolyzer. Although water or steam electrolysis is well known to be one of the cleanest ways to produce hydrogen, widespread utilization is hindered by high operational costs because of high electricity consumption. To decrease the electrical power input requirements in electrolysis, our approach uses natural gas as an anode d...

In power station practice, work is extracted from expanding steam in three stages namely High Pressure(HP), Intermediate Pressure(IP) and Low Pressure(LP) turbines. During the expansion process in the LP turbine, the steam cools down and at some stages, it nucleates to become a two-phase mixture. It is well-acknowledged in the literature that the nucleating and wet stages in steam turbines are ...

A 23 year old female diagnosed as acne vulgaris underwent Therapeutic fasting (TF) and other naturopathy and yoga modalities for 30 days. She presented with eruptions all over her face and the face was edematous. She was given a modified diet for initial 3 days which included fresh fruits and juices along with cooked vegetables and sorghum roti. Additionally Naturopathy treatments like Swedish ...
