The Paper presents the disassembly module. The module is an integral part of expert system that is partial implementation of the Technical Mean Recirculation Method (TMRM). The Disassembly module is divided to two separate sub-modules like: Structure and Sequence. The Structure sub-module is used to input technical mean structure and joins (connection character joins), between elements. In the Sequence sub-module the syndrome identify tag is created to which mechanically used and damaged elements are assigned. As result of gained data algorithm analysis, automatically the disassembly documentation is generated with rule of minimal disassembly range taken in consideration. User have also possibility to modify the operation contents or prepare a sequence manually.

The paper presents aggregation module and the author's Interchangeable Refurbishment Method (IRM). The aggregation module is an integral part of expert system that aid the overhaul process preparation. By operation oriented to the abstracts (technical documentation, structure, symptoms and list of damaged or mechanically used elements) reveals possibility of estimation: which elements should be replaced and which should be examined. Next the Interchangeable Refurbishing Method is proposed, in which mechanically used or damaged elements assigned to syndrome are replaced, by what time for further examination and refurbishment is simultaneously gained. Furthermore with provided aggregation, assignment of element a copy is possible and placement of that copy. The Aggregation module by automatically assignment of elements to replacement or further examination, improve stage of initial decision in the author's Technical Mean Recirculation Method (TMRM). The Aggregation is based on data gained form technical documentation, what are: element complexity, mass and joins quantity. Relative cost based on results is determined.

Ze względu na recyrkulację można konstruować środki techniczne bądź przygotowywać dokumentację regeneracyjną. Recyrkulację środka technicznego można zautomatyzować z zastosowaniem technik wspomagania komputerowego. Po wstępnej agregacji elementów do badań lub wymiany, elementy wybrane do dalszych badań stają się celem przeprowadzenia dokładnej (zależnej od dostępności sprzętu) oceny stanu technicznego. Na podstawie danych dyskretnych analizy uszkodzeń, zużycia i kosztów następuje agregacja technologii regeneracji i wygenerowanie jej dokumentacji.

Purpose: Disassembly and aggregation procedures are main aspects of an overhaul process. The paper presents the example of an application that solves automation of technical mean recirculation procedures. Automation in the aspect of overhaul process preparation should be obtained through new tools specially oriented to refurbish mechanically used or damaged components. Design/methodology/approach: Methodology is based on complex overhaul process analysis that conclude technical mean recirculation method. This method brings technical mean back to operation with procedures (like: disassembly, aggregation, examination, preparation of refurbishing technology, overhaul process report generation) determined in specific order. Findings Method of technical mean refurbishing with computer aid application. Proposition of automation in aspects of: disassembly (disassembly correct sequence) and aggregation procedures (which elements should be examined). Research limitations/implications: Important limitations are: disassembly based on assembly order, automation widest range possible when disassembly and aggregation is based on existing documentation. Aggregation algorithm based on machined type of elements. Practical implicatioii: Nowadays overhaul processes are based directly in most cases on leading technologist experience. Elaborated method and application leads to more objective solutions (decisions) based on algorithms results. Originality/value CAO is an original and new approach that should be considered especially in heavy industry. Nowadays subjective decisions about how to refurbish in overhaul processes could be replaced by automated computer aided solutions. Positive economic impact to future and present overhaul processes execution in industry.

Podatek dochodowy od przedsiębiorstw jest istotnym źródłem dochodów budżetowych. Jego konstrukcja jest dość złożona. Jest ona jedną z przyczyn relatywnie wysokich kosztów związanych z gromadzeniem i przetwarzaniem informacji dla celów podatkowych (koszty przedsiębiorców) oraz kosztów kontroli podatków (koszty administracji podatkowej). Sytuacja ta przyczynia się między innymi do rozwoju szarej strefy gospodarczej. Jej wielkość w Polsce szacuje się na poziomie około 24% PKB. Uzasadnione wydaje się zastąpienie podatku dochodowego od przedsiębiorstw podatkiem przychodowym, którego konstrukcja jest prostsza, a kontrola mogłaby być bardziej skuteczna.

Corporate income tax (CIT) provides substantial income for the State budget. The tax struc-ture and regulations are quite complex which result in relatively high costs associated with collecting, storing and processing information necessary for effective and efficient tax collection, in particular information about the costs incurred by entrepreneurs in their business activities. Current CIT regulations have also a significant impact on the cost of tax administration and contribute to the development of shadow economy. It is assessed that the size of shadow economy in Poland is about 24% of the total Poland’s GDP. Therefore, many economists argue that corporate income tax should be replaced by the tax calculated on the revenue instead of income, which is simpler and therefore tax collection could be cheaper and more effective.

W artykule poddano analizie wybrane spółki z sektora elektroenergetycznego funkcjonujące w USA i Polsce. Celem artykułu jest ocena kondycji finansowej tych podmiotów pod kątem źródeł ich finansowania, uzyskiwanej rentowności oraz płynności finansowej. W oparciu o przeprowadzoną analizę można stwierdzić, że spółki amerykańskie stosują w praktyce bardziej agresywne strategie finansowania, w większym zakresie korzystając z dźwigni finansowej. Przedsiębiorstwa funkcjonujące w Polsce do finansowania majątku wykorzystują przeważnie kapitał własny, co wynika głównie z uwarunkowań prawnych oraz struktury właścicielskiej. Istnieje jednak duże prawdopodobieństwo, że takie czynniki jak: istniejący stan techniczny, polityka klimatyczna UE oraz rozwój energetyki rozproszonej, mogą spowodować zmianę obecnych strategii finansowania polskich przedsiębiorstw.

The article shows the analysis of selected companies from the electric power industry in the USA and Poland. The purpose of this article is to assess the financial condition of these entities in terms of their sources of financing, profitability and liquidity. Based on the analysis it can be concluded that U.S. companies use in practice more aggressive strategies, to a greater extent by using financial leverage. Enterprises operating in Poland use mostly equity. It is mainly due to legislative framework and ownership structure. However, there is a high probability that factors such as: existing technical infrastructure, EU climate policy and the development of distributed energy, may change the current financing strategies of Polish companies.

In this paper alternative methods of the artificial lures manufacturing are presented. Proposed approach is based on application of various contemporary techniques it is reverse engineering rapid prototyping and manufacturing and middle-end CAD modeler. It is proposed to use reverse engineering not only for gathering of existing parts 3D geometry but also for acquiring it just from fish. Moreover if there is a possibility to gather information about fish skin texture, with high end 3D scanners, the real-looking fishing lures would be produced. These scanned models are usually sufficiently good for production with rapid prototyping apparatus. In order to meet a client needs application of the middle-end CAD modeler – Inventor is proposed. It allows modeling a product geometry which is well matched to a client needs and requirements. Finally vacuum casting rapid manufacturing method for a small batch production of soft fishing lures is suggested. This paper gives an application example of each above mentioned methods

The pulsed neutron generator in the Institute of Nuclear Physics in Kraków operates as a pulsed and/or stationary neutron source. Its experimental set-up for research of the time-dependent thermal neutron fields in various media is presented. The electronic control systems for the generator and for data acquisition, necessary to assure the required measurement conditions, have been designed and built by the authors. The new electronic equipment makes it possible to do the measurements with high accuracy and repeatability. The macroscopic absorption cross section for environmental materials, like rocks, borehole and formation fluids, are measured routinely using the pulsed neutron source by two methods elaborated in the INP. The pulsed neutron parameters for homogeneous and heterogeneous materials (e.g. containing absorbing centres in a low absorption matrix) can be also measured by the geometrical buckling method on the same experimental set-up. Experiments for materials of variable bulk densities are going on. Other experiments are related to a verification of new theoretical models of thermal neutron scattering in hydrogenous media.

Generator neutronów prędkich działający w Instytucie Fizyki Jądrowej im. Henryka Niewodniczańskiego w Krakowie może pracować zarówno z wiązką ciągłą, jak i impulsową. W pracy opisane jest stanowisko pomiarowe do badania niestacjonarnych pól neutronowych w różnego rodzaju ośrodkach. Systemy sterowania i kontroli generatora neutronów i stanowiska pomiarowego oraz układy zapewniające utrzymanie odpowiednich i stabilnych warunków pomiarowych zostały zaprojektowane i wykonane przez zespół autorów. Nowoczesne rozwiązania elektroniczne umożliwiają wykonywanie pomiarów z wysoką dokładnością i powtarzalnością. Obecnie stanowisko pomiarowe wykorzystywane jest do pomiaru przekroju czynnego absorpcji neutronów termicznych dla materiałów geologicznych dwiema metodami impulsowymi opracowanymi w IFJ. Ponadto metodą zmiennego bucklingu geometrycznego wyznacza się tzw. impulsowe parametry neutronowe dla ośrodków jednorodnych i niejednorodnych (np. centra absorpcyjne w słabo absorbującym medium). Wykonuje się również eksperymenty dla materiałów o zmiennej gęstości nasypowej. Stanowisko może też być wykorzystywane do eksperymentów służących weryfikacji badań podstawowych dotyczących procesów spowalniania, rozpraszania i dyfuzji neutronów w ośrodkach o ograniczonych rozmiarach, w szczególności zawierających wodór związany w molekułach.
