Opis:
Procesy stygmatyzacji i marginalizacji społecznej byłych skazanych stanowią istotną przeszkodę w ich społecznej readaptacji. Efekty osiągnięte w drodze resocjalizacji penitencjarnej w trakcie odbywania kary pozbawienia wolności są niewystarczające dla ich usamodzielnienia się w środowisku wolnościowym w zestawieniu z reakcją niechęci społecznej i odrzucenia. Celem artykułu jest przedstawienie roli zinstytucjonalizowanej pomocy postpenitencjarnej w przeciwdziałaniu stygmatyzacji i marginalizacji społecznej byłych skazanych. W artykule wyjaśnione zostało pojęcie stygmatyzacji i marginalizacji społecznej, znaczenie oddziaływań resocjalizacyjnych w kontekście przygotowania skazanego do zwolnienia z zakładu karnego oraz zakres i formy pomocy postpenitencjarnej. Dla potrzeb wyjaśnienia stygmatyzacji posłużono się teoriami naznaczenia społecznego.
The processes of social stigmatisation and marginalisation of former convicts form a serious obstacle to their social re-adaptation, The effects achieved as part of penitentiary resocialisation while serving a prison sentence are insufficient for them to become independent in free society, combined with the reaction of social reluctance and rejection. The purpose of this article is to present the role of institutionalised post-penitentiary assistance in counteracting social stigmatisation and marginalisation of former convicts. The article explains the notion of social stigmatisation and marginalisation, the meaning of resocialisation activities within the context of preparing an convict for releasing him/her from a correctional facility, as well as the scope and forms of post-penitentiary assistance. For the purposes of explaining stigmatisation, the author used theories of social stigma.

Opis:
The geometrical accuracy of the products are essential for high quality and interchangeability. Lapping processing is mostly using for final improvement of geometrical accuracy. Geometrical accuracy includes cylindricity, circularity and straightness. In this paper, lapping processing using a normal lathe was investigated for improvement of geometrical accuracy. Firstly, normal turning process is taken and then, the lapping process is performed using the same lathe. The lapping tool consists of a lapping head made of polypropylene (PP), a coil spring for supplying lapping pressure and holder for fitting on tool post. Lapping slurry is composed by mixing water, PEO (Polyethylene Oxide) and diamond grain. This lapping slurry is supplied between the work piece and the lapping head during lapping processing. The lapping head is made to contact and leave from work piece in regular intervals for catching new grains and removing chips. The optimum lapping condition was investigated for high productivity and high accuracy by experiments. It is concluded from the results that; (1) The geometrical accuracy were improved by using developed lapping system with ordinary lathe machine. (2) The optimum lapping condition was revealed experimentally. (3) The surface roughness and dimensional accuracy are also improved using this developed lapping system.

Opis:
Is this article simulation of statistical measurements is performed on the basis of which the analysis of the standard deviation of the obtained results is carried out. It is shown that the standard deviation is minimum and independent from measurement duration while an object is in the state of equilibrium. For objects in a stationary non-equilibrium state the standard deviation depends on the duration measurements and the parameters of the state. The influence of these factors on the standard deviation is assessed with equation which includes the relaxation time. The value of the relaxation time is determined by approximating the energy spectrum of the studied signals. The analysis of energy spectra showed that the spectrum of white noise is inherent in objects in equilibrium; the flicker component of the spectrum occurs when the state of the object deviates from equilibrium.

Opis:
In this paper, the deviation from eutectic composition in boundary layer for eutectic growth is studied by phase-field method. According to a series of artificial phase diagram, the lamellar eutectic growth of these alloy is simulated during directional solidification. At steady state, average growth velocity of eutectic lamella is equal to the pulling velocity. With the increasing of the liquidus slope of β phase, the average composition in boundary layer would deviate from eutectic composition and the deviation increases. The constitutional undercooling difference between both solid phases caused by the deviation increases with the increasing of the deviation. The β phase would develop a depression under the influence of the deviation.

Opis:
During the production process one should operatively survey pre-established (standard) costs with a view of determining and analyzing deviations as costs are settled at the level of an activity considered to be normal while real activity can display deviations from this. The system of analysis and control of standard costs differs depending on the direct or indirect character of the expenditures. Nevertheless, irrespective of the character of the expenditures, the analysis and control of standard costs have as a goal the determining (calculation) of deviations, namely of the minus or plus differences between real costs and standard costs. The final objective is the finding out of the causes that have determined deviations, the adopting of corrective measures, and the determining of responsibilities. As regards raw materials and direct materials, deviations represent plus or minus differences as a result of: exceeding or disregarding specific consumptions, price changes, and the use of materials having other sizes or quality as compared with the ones envisaged by the budget, etc. (JEL: C13, D24, L23).
Podczas procesu produkcji należy prowadzić badania ustalonych z góry (standardów) kosztów w celu określenia i analizowania odchyleń kosztów rozliczanych na poziomie działalności, podczas gdy rzeczywiste działania mogą wykazywać od nich odstępstwa. System analiz i kontroli kosztów standardowych różni się w zależności od bezpośredniego lub pośredniego charakteru wydatków. Niemniej jednak, niezależnie od charakteru wydatków, analizy i kontrola kosztów standardowych, mają na celu określenie (obliczenie) odchyleń, czyli ujemnych lub dodatnich różnic między rzeczywistymi kosztami a kosztami standardowymi. Ostatecznym celem jest ustalenie przyczyn, które powodują odchylenia, podjęcie działań naprawczych i określenie obowiązków w tym zakresie. W odniesieniu do surowców i materiałów bezpośrednich, odchylenia stanowią dodatnie lub ujemne różnice, jako efekt: uwzględniania szczególnej konsumpcji, zmian cen oraz stosowania materiałów o innych rozmiarach i jakości w stosunku do tych przewidzianych w budżecie, itp.

The two-dimensional compressor flow simulation approach has always been a very valuable tool in compressor preliminary design studies, as well as performance predictions. In this context, a general development of the streamline curvature (SLC) method is elucidated firstly. Then a numerical method based on SLC is developed to simulate the internal flow of the compressor according to the development analysis and conclusion. Two certain transonic axial compressors are calculated by this 2D method. The speed lines and span-wise aerodynamic parameters are compared with the experiment data in order to demonstrate the method presented in this paper.

Opis:
New materials require the use of advanced technology in manufacturing parts of complex shape. One of the modern non-conventional technology of manufacturing difficult to cut materials is the wire electrical discharge machining (WEDM). The article presents the results of theoretical and experimental research in the influence of the WEDM conditions and parameters on the shape deviation during a rough cut. A numerical model of the dielectric flow in the gap (ANSYS) was developed. The influence of the dielectric velocity field in the gap on the debris evacuation and stability of WEDM process was discussed. Furthermore, response surface methodology (RSM) was used to build empirical models for influence of the wire speed Vd, wire tension force Fn, the volume flow rate of the dielectric Qv on the flatness deviation after the WEDM.

Opis:
The article puts forward a hypothesis about the role and the place of “destructive deviations” in identifying indicators of crises that a city is going through, in the processes of its functioning as a complex dynamic system. It also proposes a hypothesis about classification of “destructive deviations” in architecture according to their type and development scenario. The problems of their influence on the transition of a city from a steady state to a crisis and a possible catastrophe are considered. The characteristics of a city system development are viewed in the context of interaction between the forces of stability (order) and changes (development). At the same time, the fact of inevitability of intersystem conflicts in such a complex formation as a city is regarded as obvious. In the conducted study, the concept of “Destructive deviations” is part of the method of identifying “Crisis indicators” , which, in turn, is necessary to create a model complex designed for modeling, analyzing and managing the architectural component of a city as a dynamic system.

Opis:
The article tackles the problem of evaluating the errors in production and installation of bevel gear which have impact on the transmission error. The production defect has been determined as an incorrect construction of bearing openings causing the change of angle between the axes toothed gears and installation error – as failure to meet the mounting distance of crown wheels. The tests were conducted as simulative tests mainly due to the time and cost of tests. Toothed gears were modeled as solid models and then a virtual installation and a single flank testing were conducted. As a result, data about the positions of angular toothed gears were received on the basis of which the transmission error was calculated. This error reflects the constancy of the driven shaft’s rotational speed and thus it is associated with the gear’s vibration and acoustic activity.

In this article, the study's results of aircraft’s coordinates and their accuracy are presented. The airborne test was conducted in military airport in Deblin on 1st of June 2010. The aircraft position was determinate using SPP method in RTKPOST library in RTKLIB software. To calculate the aircraft’s coordinates two strategies were used, first include correction of atmosphere delays (I solution) and another without this correction (II solution). Based on these calculations, the average accuracy of aircraft position is less than 5 m for solution I and less than 8 m for solution II, respectively. The mathematical model for recovery of aircraft position; the configuration of parameters in SPP method for solution; the standard deviation values of X, Y and Z coordinates; the values of RMS-3D parameter are presented in the article. In this article, the impact of ionosphere and troposphere delay in processing of recovery of aircraft position is presented. The aircraft’s coordinates were obtained using SPP (Single Point Positioning) method for two solutions, e.g. including atmosphere corrections (I solution) and excluding (II solution). The article is divided into 5 sections: introduction, mathematical model for recovery of aircraft position, research experiment, results and discussion, conclusions.
