Cableways for timber transportation are quite effective in terms of manufacturability, specific energy consumption, material capacity and the negative impact level on environment difficult natural operating conditions, compared to similar types machines. Since non-stationary cableways usually used forestry production, which characterized by a light construction with relatively small safety marg...

Radiographic or silver halide film is a well-established 2D dosimeter with an unquestioned spatial resolution. But its higher sensitivity to low-energy photons has to be taken into consideration. Metal compensators or physical modulators to deliver intensity modulated radiation therapy (IMRT) are known to change the beam energy spectrum and to produce scattered photons and contaminating electro...

In this paper, simultaneous strong stabilization problem is considered, and it is shown that there is no upper bound for the minimal order of a simultaneously strongly stabilizing compensator, in terms of the plant orders. A similar problem was also considered in 1111, where it was shown that such a bound does not exist for the strong stabilization problem of a single plant. But the examples gi...

This paper will compare a number of PID and predictive controller strategies to compensate processes modelled in first order lag plus time delay (FOLPD) form. The performance and robustness of the resulting compensated systems are evaluated analytically (where appropriate) and in simulation.
