Modeling of strip winder control

Jednym ze sposobów wzmacniania komór ciśnieniowych jest owijanie rury rdzeniowej cylindra nawojem taśmy. Aby uzyskać wymaganą jakość takiej komory, należy w procesie nawijania taśmy zapewnić w pełni kontrolowaną i stabilną siłę jej naciągu. Realizowany projekt maszyny do nawijania obejmuje również układ sterowania zespołu napędu i hamowania. Przedstawiona zostanie metoda symulacji Hardware in the Loop, wykorzystująca sterownik przemysłowy i program LabView.One of the ways to enhance the working pressure of vessels is to reinforce the cylinder by means of a multiple-layered strip wound. In order to obtain the required quality of such a vessel, a fully controlled and stable strength of the strip tension must be ensured in the course of the winding process. The design of the winding machine also includes control systems of propulsion and braking. The Hardware-in-the-Loop simulation method has been presented using an industrial driver and the LabView software

Communication issues in the control system of reactive power compensator for hydroelectric plant with induction generator

The presented paper concerns the issues of communication networks applied to monitoring and control of reactive power compensator for small hydroelectric plants installed in areas distant from urban agglomerations. Ethernet, CAN, Modbus and GPRS transmission protocols has been used. Industrial programmable controller as a data collector has been used also

Ultrafiltration plant for egg white dehydration

Praca opisuje instalację stanowiącą część linii technologicznej wytwarzania białka jaja w proszku. Przedstawia podsumowanie działań inżynierskich autorów podjętych w celu modyfikacji tradycyjnego procesu wykorzystującego tylko wieżę rozpyłową. Dzięki wykorzystaniu szeregu dodatkowych elementów, takich jak wymiennik ciepła, wirówka, zaprojektowana autorska instalacja ultrafiltracyjna oraz dozownik enzymów osiągnięto znaczne zmniejszenie zapotrzebowania procesu na energię. Założenia projektowe obejmowały możliwość obróbki 4 000 l białka/h. W ciągu ponad 3 lat opisana instalacja wyprodukowała ok. 40 milionów ton zagęszczonego białka

Ethics in contemporary health care management and medical education

Rationale The health care landscape is changing: it has become the largest part of the economy and changes in public management systems will greatly affect how we practice medicine in the future. Medical education will be more important than ever to ensure patients get the best care with empathy. However, new public management systems implemented without thorough analysis might challenge medical education. An increasing number of public health care institutions provide services based on competitive market rules and express their goals in financial terms and have set financial gains as their main goal, which contradicts the fundamental nature of medical ethics and practice. Aims and objectives To explore new public management to identify potential problems and offer possible solutions for medical education and health care institutions. Methods A scoping review of the literature on public administration, hospital management, professionalism, ethics, and medical education was undertaken to map evidence on the topic and identify main concepts and knowledge gaps in the influence of management systems on the quality of medical educational practices. Results If the accelerating changes in public management are cursorily analysed, medical education may lose the esteem in which it has long been held globally. Without precautions, the so-called new public management medical faculties will-at best-generate economic benefit, following a business model with strict quality rules, regulations, standardized products, and complex analysis and measurement systems. However, these faculties will function at a level far below the ideal of teaching institutions distinguished for their outstanding components, creativity, and ambience. Conclusions Patients and teaching values are not reducible to financial terms only and the acknowledgement of non-financial values is fundamental to achieve quality in health care and education. The most essential step could be selecting managers who will implement public management principles while taking into account both business requirements and medical ethics.Scientific Assessment and Innovation in Neurosurgical Treatment Strategie
