Opis:
A new measuring point localization method based on fractal geometry for water quality monitoring in water network was presented. The proposed method belongs to the group based on individual network point suitability rankings for localization of monitoring sensors. The method concept as well as tables of indexes essential for its practical application were presented. In addition to technical criteria, measuring point localization indications include economic criterion as well. Method used for assessment of this localization accuracy enabled numeric comparison between the considered options and selection of the best one. The proposed method was successfully tested for water network in Pulawy.
W artykule zaprezentowano nową metodę lokalizacji punktów pomiarowych monitorowania jakości wody w sieci wodociągowej z wykorzystaniem geometrii fraktalnej. Proponowana metoda należy do grupy wykorzystującej rankingi przydatności poszczególnych punktów sieci do celów lokalizacji czujników monitoringu. Przedstawiono zarówno koncepcję metody, jak również tablice wskaźników niezbędnych do jej zastosowania w praktyce. Wskazania lokalizacyjne punktów pomiarowych obejmują, obok kryteriów technicznych, także kryterium ekonomiczne. Zastosowana metoda oceny prawidłowości tej lokalizacji umożliwiła liczbowe porównanie ze sobą rozpatrywanych wariantów i wybór najlepszego spośród nich. Proponowaną metodę przetestowano z sukcesem w warunkach sieci wodociągowej w Puławach.

Opis:
The publication analyses the way of managing and improving the quality of the production process of aluminum pistons for internal combustion engines. The aim of the article is to propose a method of analysis of the effectiveness of individual control methods used in the process of controlling the aluminium piston. Thanks to the location of a control point with the highest share of product non-compliance detection in the production process, it is possible to reduce quality control points by less effective points, which will contribute to lower costs or shorten the time of production processes. In view of the increasing demands on the efficiency of the checkpoints for components in internal combustion engines, the issue is important and topical.

Opis:
In carbohydrate-starved root meristems of Vicia faba subsp. minor, the expression of two Principal Control Points located at the final stages of the G1 (PCP1) and G2 (PCP2) phases has been found to be correlated with a marked decrease of protein phosphorylation within cell nuclei, nucleoli and cytoplasm. Adopting the same experimental model in our present studies, monoclonal FITC conjugated antibodies that recognize phosphorylated form of threonine (αTPab-FITC) were used to obtain an insight about how the indole-3-acetic acid (IAA), benzyl-6-aminopurine (BAP), and the mixture of both phytohormones influence the time-course changes in an overall protein phosphorylation during sucrose-mediated PCP1→S and PCP2→M transitions. Unsuspectedly, neither IAA, BAP, nor the mixture of both phytohormones supplied in combination with sucrose did up-regulate protein phosphorylation. However using the block-and-release method, it was shown that root meristems of Vicia provided with sucrose alone indicated higher levels of αTPab-FITC. Contrarily, phytohormones supplied in combination with sucrose induced apparent decline in phosphorylation of cell proteins, which - when compared with the influence of sucrose alone - became increasingly evident in time. Thus, it seems probable, that a general decline in the amount of αTPab-FITC labeled epitopes may overlay specific phosphorylations and dephosphorylations governed by the main cell cycle kinases and phosphatases.

Opis:
Relay-based railway signalling systems are constructed with safety relays, which are produced by the main signalling manufacturers. Such safety relays are hard to find on the market. Therefore signalling contractors frequently use small-sized, easily-available relays of the SF4 and H-464 type, which conform with the UIC736 normative requirements. The paper presents safety relays of the H-464 type as well as three-phase switch point control circuits, which are based on such relays cooperating with switch point transducers and utilized in centralised mechanical signalling systems with electrical switch-over of the switch points.

Opis:
This article presents properties of a follow-up system executing ship’s rudder deflection using a constant delivery hydraulic pump. Furthermore, a solution is discussed which increases static and dynamic accuracy of such a system using the rudder angular velocity signal. This signal has been used for changing the level of a three-position controller insensitivity. The paper also shows the method of determination of the function describing variations of dead-zone width of the three-point controller. Two kinds of such function are shown, namely linear and quadratic. A computer model was prepared in MATLAB-Simulink environment, showing the operation of the system with correction of error signal, which carries out given by function variations of points of switching. Also included are the simulation results of the described solution, indicating a significant enhancement of accuracy of rudder angle control process for the steady state as well as during transients.

Opis:
In this paper we consider point control of a structural acoustic model with thermoelastic effects. The key feature of this paper is that the two-dimensional plate modeling the active wall of the acoustic chamber has clamped boundary conditions. For this case a new optimal regularity result has recently become available (Triggiani, 2008). Using this new result for the plate alone, we derive a sharp (optimal) regularity result for the overall coupled system of wave and thermoelastic plate equations, after overcoming a series of additional technical difficulties. This allows for the study of an optimal control problem of the coupled system.
