Considering the issue of Polish Special Services legal position requires referring to many specific matters. It is essential to explain the definition of "special services" in the Polish legal system. Firstly, it is necessary to describe what state institutions belong to special services. The analysis of the Polish law shows that the term "special services" is used only in two legal acts. They are: The Law on Internal Security Agency (the ABW) and Intelligence Agency (the AW), passed on the 24th May 2002, and The Law on Military Information Services (the WSI), passed on the 9th July 2003. Other legislation either does not know the term "special services" at all, or it is used in the context of defining the co-operation with institutions that the special services apply to. In the regulations concerning the ABW and the AW the term "special services" is used in article 11 and the following, whereas the act on the WSI uses it in article 1.2. As a consequence of these regulations we can say about the strict list of the Polish Special Services which include only three state institutions: Internal Security Agency, Intelligence Agency and Military Information Services. Such direct pointing in article 11 makes the issue of the special services beyond doubts. Secondly, what seems to have decided of such an approach to the issue of the secret services is the range of tasks which these three institutions are supposed to perform. The objects of the interests of the special services are intelligence and counterintelligence actions. They are reserved only for the ABW, the AW and the WSI. They are not taken by other state organisations dealing with state security such as: Police, Border Guard, Government Protection Bureau and Military Police. The connection between intelligence, counterintelligence and the state security is so obvious that the special treatment of institutions taking this kind of actions should not be a surprise. It is also the first step towards indicating the place of the special services in that part of the legal system that is responsible for providing the state security. The character of these tasks causes more and more noticeable organisational isolation of the special services from the structure of the State. These services, on ground of legislation of 2002 and 2003, are still dependent of constitutional executive authorities. But the situation of the ABW and the AW has profoundly changed. Since 2002, these two institutions have been subordinated to the Prime Minister. They are led by the Chiefs of the ABW and the AW, who are directly subordinate to the Prime Minister. The WSI is supervised by the National Defence Minister, as it has been to date. What changed in 2002 is the fact that the positions of the ABW and the AW chiefs were established instead of the Minister Co-ordinator for Special Services. The rule is that these Services are led by the Chiefs who are not officers but civilians. That last change influences the character of the ABW and the AW as the civil special services. On the one hand, their tasks and activity have to be apolitical. On the other hand, the civil status of their chiefs gives an opportunity to fill these positions by members of political parties. Obviously, the fact that they are staffed by politicians does not have to mean that the Services are political. The transparency of the system is important. This regulation is open to doubt as far as the constitutional rule of the parliament is concerned. The point of this rule is the government's answerability to the Parliament. The government is a creation of a party or a coalition having a majority to support the government. Members of the government are also answerable to the Parliament individually. Consequently, the Parliament has the power to react up immediately to every minister's actions. However, the Parliament cannot apply that towards the Chiefs of the ABW and the AW because they are not members of the government formally, despite the fact that their factual status is basically not different from the position of any minister who is not in charge of a particular government department.

Artykuł ma na celu wskazanie wybranych determinantów efektywnego wdrożenia filozofii Lean Manufacturing (LM) w przedsiębiorstwach produkcyjnych. Opierając się na definicji LM zaprezentowano cztery czynniki, które mają największy wpływ na skuteczność implementacji nowego podejścia w zarządzaniu produkcją. Te czynniki to: dobór odpowiedniego modelu zarządzania zmianą, praca zespołowa, wdrożenie jednolitego systemu szkoleń stanowiskowych, dostosowanie zasad rachunkowości finansowej i zarządczej do wymagań LM. Każdy z wymienionych wyżej czynników został szczegółowo zdefiniowany wraz z dokonaniem oceny ich oddziaływania na skracanie czasu między złożeniem zamówienia przez klienta a wysyłką towaru do końcowego odbiorcy poprzez eliminowanie marnotrawstwa ze strumienia wartości.

The aim of the paper is to identify, on the basis of selected examples, the effectiveness of Lean Manufacturing (LM) and Six Sigma (SS) techniques in a large-production enterprise characterized by low-volume production, a wide product range, stabilized manufacturing technology and a so-called "brownfield" site. Many scholars have attempted to answer which approach, LM or SS, is more effective in a production enterprise. The authors of the paper aim to answer this question on the basis of a detailed analysis of efficiency of implementation of both techniques. The amount of savings generated from undertaken projects and increase of profitability of the analysed production system have served as performance measurements.

This paper deals with fault location in three-terminal overhead lines by means of two-end synchronized measurements. The delivered fault location algorithm consists of three subroutines, designated for locating the faults in particular line section and the procedure of selecting the valid subroutine. All subroutines are formulated for the natural fault loops, which is distinct from the up-to-date approach. This has been applied with the aim of minimising the adverse influence of uncertainty with respect to impedance data of equivalent sources behind the line terminals upon the fault location accuracy. The selected results of fault location accuracy evaluation performed with the use of fault data obtained from ATP-EMTP simulations are presented and discussed.

W artykule rozpatrzono lokalizację zwarć w liniach napowietrznych z odgałęzieniem z użyciem synchronicznych pomiarów na dwóch końcach linii. Przedstawiony algorytm składa się z trzech procedur lokalizacji, przeznaczonych do lokalizacji zwarć w poszczególnych sekcjach linii, oraz procedury wyboru obowiązującej procedury lokalizacji. W odróżnieniu od dotychczas stosowanego podejścia, wszystkie procedury lokalizacji zostały sformułowane dla naturalnych pętli zwarciowych. Zastosowano to w celu ograniczenia niekorzystnego wpływu niepewności danych w odniesieniu do inipedancji ekwiwalentnych podsystemów z końców linii na dokładność lokalizacji. Zamieszczono i omówiono wybrane rezultaty analizy dokładności lokalizacji zwarć, przeprowadzonej z użyciem przebiegów uzyskanych z symulacji zwarć z pomocą programu ATP-EMTP.

W artykule rozważono stosowanie kompletnych pomiarów z jednego końca dwutorowej linii elektroenergetycznej. Pokazano, że przy tej dostępności sygnałów pomiarowych problem określenia miejsca zwarcia w linii dla celów inspekcyjno-remontowych jest w pełni rozwiązalny i nie trzeba stosować założeń upraszczających. Wykazano, że możliwe jest wprowadzenie adaptacji, zapewniającej całkowite wyeliminowanie niekorzystnego wpływu rezystancji w miejscu zwarcia na działanie zabezpieczenia odległościowego. Podano reprezentatywne przykłady ilustrujące zalety stosowania przedstawionych algorytmów. Artykuł recenzowany.

Use of complete measurements from one end of a double-circuit power line has been considered. It has been shown that under such availability of measurements, an issue of fault location for inspection-repair purposes becomes completely solvable and there is no need for applying simplifying assumptions. It has been proved that it is possible to introduce an adaptation, which assures complete compensation of adverse influence of fault path resistance on operation of distance protection. Representative examples, which illustrate advantages of applying the presented algorithms, have been included.

The article describes the concept of measurement of the mechanical strength of trabecular bone dissected from human femoral head. When the studies are performed based on the human trabecular bone, there is a risk that correlation can be not achieved due to high discrepancy in the distribution of the bone density and mechanical properties. The compressive tests and X-ray microcomputed tomography with associated density phantom were used to deliver quantitative data. There is a conclusion that the selection of the region in the femoral head has to be performed very carefully. The region where cylinder is dissected can influence the results and produce fake data, which could not be correlated in the density of bone.

Nowadays, in urbanized areas one of the most important matters is to determine a priori the time of driving from one zone of the city to another at various times of the day. The problem of travel time prediction is crucial in Intelligent Transportation Systems. The solution to this problem is a foundation of any route guidance system that will redirect drivers to their target destination via routes that have a lighter traffic load and thus higher travel velocity. In this paper is present a concept of a statistical methodology, developed by the ArsNumerica Group, that enables a quantity audit a travel time prediction algorithm. The methodology assumes that we are given database records of vehicles recognized by their unique identifier as well as duration times for which the messages with the predicted travel time are displayed VMS. the second aspect of ITS auditing considered in this paper is a placement of video cameras to measure vehicle stream velocity. Inappropriate camera location results in the fact that the stream velocity measured by them has a low usefulness for travel time prediction.
