Opis:
The purpose of the article is to analyse Immanuel Wallerstein's approach towards social change and to compare it with the concept of macrosocial change in modernization theories. The main thesis proposed by the authoress is that although Immanuel Wallerstein declares that perception of social change as framed by the 'ahistorical models' (such bias being typical of modernization theories) should be abandoned, he nevertheless advances a model which is equally ahistorical.
Celem artykułu jest przybliżenie i analiza ujęcia zmiany społecznej w teorii systemu światowego Immanuela Wallersteina oraz porównanie jego koncepcji z ujęciem zmiany w teoriach modernizacji. Autorka stoi na stanowisku, że choć Wallerstein deklaruje konieczność zerwania z ujmowaniem zmiany społecznej w ramach „modeli ahistorycznych” (ku którym zwracają się teorie modernizacji), proponuje w istocie model równie ahistoryczny.

Opis:
Konsensualny sado/masochizm pozostaje pośród najbardziej potępianych praktyk seksualnych podejmowanych dobrowolnie przez osoby dorosłe. Główna kontrowersja dotyczy interpretacji podejmowanej przemocy. Nauki społeczne podjęły alternatywną i krytyczną wobec tradycji klinicznej refleksję nad sadyzmem i masochizmem. Zachodzące w przestrzeni społecznej procesy ujmowania w ramy i przekształcenia interpretacyjne mogą być opisane z pomocą analizy ramowej Ervinga Goffmana. W szerszym planie ta krańcowa i wyrazista sytuacja ukazuję rolę, jaką w pracy instytucji normalizacyjnych, prawnych, medycznych może odgrywać zewnętrzna interpretacja zdarzeń dokonywana przez ich przedstawicieli, odmienna od interpretacji podejmujących te praktyki społeczne. Fakt ten musi jednak pozostać nieuświadomionym, by instytucje te mogły operatywnie działać.
Sadomasochism still is one of the most intensively criminalized sexual practices undertaken by consenting adults. The main controversy regards the interpretation of the violence acts involved. Social sciences have undertaken an alternative reflection on sadism and masochism, critical towards the clinical tradition. The interpretation processes, and framing of activities may be described using Erving Goffman's frame analysis. In the broader perspective this extreme and striking situation demonstrates the role played in the normalizing social control institutions such as justice administration or medical bodies by the external interpretative procedures carried out by their representatives, as differing from the interpretations of the persons conducting this sort of social practices. However, this influence needs to stay unconscious in order for these institutions to operate in an efficient manner.

Opis:
The main goal of introducing Active Suspension System in vehicles is to reduce the vehicle body motion under road obstacles which improves the ride comfort of the passenger. In this paper, the Full Car Model (FCM) with seven Degrees of Freedom is considered and simulated by MATLAB/Simulink. The Terminal Sliding Mode Controller (TSMC) and Fractional Order Terminal Sliding Mode Controller (FOTSMC) are designed to enhance the ride quality, stability and passenger comfort for FCM. The designed FOTSMC has the ability to provide higher control accuracy in a finite time. The performances of the designed controllers are evaluated by measuring the vehicle body vibration in both angular and vertical direction under bump input and ISO-8608 random input against passive suspension system. The Frequency Weighted Root Mean Square (FWRMS) and Vibration dose value of Body Acceleration as per ISO-2631 are evaluated for FOTSMC, TSMC and PSS. The stability of the FCM is proved by Lyapunouv theory. Further analysis with sprung mass and speed variation of FCM demonstrate the robustness of proposed controller. To investigate the performances of designed controllers, comparison is made with existing Sliding Mode Controller (SMC) which proves that the designed FOTSMC performs better than existing SMC.

Opis:
The electrical power drawn by an induction motor is distorted in case of appearance of a certain type of failures. Under spectral analysis of the instantaneous power one obtains the components which are connected with definite types of damage. An analysis of the amplitudes and frequencies of the components allows to recognize the type of fault. The paper presents a metrological analysis of the measurement system used for diagnosis of induction motor bearings, based on the analysis of the instantaneous power. This system was implemented as a set of devices with dedicated software installed on a PC. A number of measurements for uncertainty estimation was carried out. The results of the measurements are presented in the paper. The results of the aforementioned analysis helped to determine the measurement uncertainty which can be expected during bearing diagnostic measurements, by the method relying on measurement and analysis of the instantaneous power of an induction machine.

Opis:
Thermal analysis of a heat and power plant with a high temperature gas cooled nuclear reactor is presented. The main aim of the considered system is to supply a technological process with the heat at suitably high temperature level. The considered unit is also used to produce electricity. The high temperature helium cooled nuclear reactor is the primary heat source in the system, which consists of: the reactor cooling cycle, the steam cycle and the gas heat pump cycle. Helium used as a carrier in the first cycle (classic Brayton cycle), which includes the reactor, delivers heat in a steam generator to produce superheated steam with required parameters of the intermediate cycle. The intermediate cycle is provided to transport energy from the reactor installation to the process installation requiring a high temperature heat. The distance between reactor and the process installation is assumed short and negligable, or alternatively equal to 1 km in the analysis. The system is also equipped with a high temperature argon heat pump to obtain the temperature level of a heat carrier required by a high temperature process. Thus, the steam of the intermediate cycle supplies a lower heat exchanger of the heat pump, a process heat exchanger at the medium temperature level and a classical steam turbine system (Rankine cycle). The main purpose of the research was to evaluate the effectiveness of the system considered and to assess whether such a three cycle cogeneration system is reasonable. Multivariant calculations have been carried out employing the developed mathematical model. The results have been presented in a form of the energy efficiency and exergy efficiency of the system as a function of the temperature drop in the high temperature process heat exchanger and the reactor pressure.

A computer measurement system, designed and built by authors, dedicated to location and description of partial discharges (PD) in oil power transformers examined by means of the acoustic emission (AE) method is presented. The measurement system is equipped with 8 measurement channels and ensures: monitoring of signals, registration of data in real time within a band of 25-1000 kHz in laboratory and real conditions, basic and advanced analysis of recorded signals. The basic analysis carried out in the time, frequency and time-frequency domains deals with general properties of the AE signals coming from PDs. The advanced analysis, performed in the discrimination threshold domain, results in identification of signals coming from different acoustic sources as well as location of these sources in the examined transformers in terms of defined by authors descriptors and maps of these descriptors on the side walls of the tested transformer tank. Examples of typical results of laboratory tests carried out with the use of the built-in measurement system are presented.

Opis:
Oxy-fuel combustion (OFC) belongs to one of the three commonly known clean coal technologies for power generation sector and other industry sectors responsible for CO2 emissions (e.g., steel or cement production). The OFC capture technology is based on using high-purity oxygen in the combustion process instead of atmospheric air. Therefore flue gases have a high concentration of CO2 - Due to the limited adiabatic temperature of combustion some part of CO2 must be recycled to the boiler in order to maintain a proper flame temperature. An integrated oxy-fuel combustion power plant constitutes a system consisting of the following technological modules: boiler, steam cycle, air separation unit, cooling water and water treatment system, flue gas quality control system and CO2 processing unit. Due to the interconnections between technological modules, energy, exergy and ecological analyses require a system approach. The paper present the system approach based on the 'input-output' method to the analysis of the: direct energy and material consumption, cumulative energy and exergy consumption, system (local and cumulative) exergy losses, and thermoecological cost. Other measures like cumulative degree of perfection or index of sustainable development are also proposed. The paper presents a complex example of the system analysis (from direct energy consumption to thermoecological cost) of an advanced integrated OFC power plant.

Opis:
The distinction between two types of diagnosis of family was inspired by the concept of surface and source features of personality by R.B. Cattell. By means of existing psychological questionnaires we can only know the surface of consciously available mental phenomena. The same is true in the diagnosis of family. The McMaster model of family, systemic in its assumptions, developed research tools giving access only to the surface of the phenomena. Although they are divided into certain thematic categories they do not reveal what is really important in the family system. In this article, the author, after a detailed discussion of one of the tests based on the McMaster theoretical model, is attempting to identify the source features (here: unavailable for conscious cognition) of the family, hereinafter called systemic traits. In this research the exploration factor analysis was used. Three perspectives of the opinion of the family were maintained (like in the Family Assessment Measure). Factor analysis allowed identification of three factors for each perspective of the family assessment. Confirmative analysis proved a satisfactory match (using RMSEA, GFI and AGFI statistics). The accuracy of the identified systemic model was then tested by a confirmation study (confirmative factor analysis using Amos from SPSS). The authors also prepared a provisional questionnaire for measuring these systemic traits of the family. The tool proved to be promising and the work worth continuing. Incidentally, it turned out that the characteristics of the family system are relatively independent of personality traits of family members.

Opis:
Wind power integration through the voltage source converter-based high-voltage direct current (VSC-HVDC) system will be a potential solution for delivering large-scalewind power to the “Three-North Regions” of China. However, the interaction between the doubly-fed induction generator (DFIG) and VSC-HVDC system may cause the risk of subsynchronous oscillation (SSO). This paper establishes a small-signal model of the VSC based multi-terminal direct current (VSC-MTDC) system with new energy access for the problem, and the influencing factors causing SSO are analyzed based on the eigen valueanalysis method. The theoretical analysis results show that the SSO in the system is related to the wind farm operating conditions, the rotor-side controller (RSC) of the DFIG and the interaction of the controller in the VSC-MTDC system. Then, the phase lag characteristicis obtained based on the signal test method, and a multi-channel variable-parameter subsynchronous damping controller (SSDC) is designed via selecting reasonable parameters.Finally, the correctness of the theoretical analysis and the effectiveness of the multi-channelvariable-parameter SSDC are verified based on time-domain simulation.

Opis:
The paper presents kinematic characteristics of the double 4-link coupler system, used in actual powertrain of low-floor trams (NGT6-Kr). The spatial kinematic model of the couplings was formulated assuming ideal joints and rigid members. The constraints equations of the mechanism were solved iteratively and differentiated to obtain the Jacobian matrix. The mobility and singularity analysis of the coupler mechanism was performed on the basis of the Jacobian matrix. Kinematic characteristics of the single and double coupler system were analyzed for gross angular and linear axle displacements (misalignments), taking the advantage of the fully nonlinear model. The coupling system was evaluated based on criteria describing homokinetics, balancing and clearance demands, and angular displacements in the joints. These criteria were determined for different design parameters like: coupler proportions, platform shift and angle, middle shaft length.
W pracy przestawiono charakterystyki kinematyczne układu napędowego z podwójnym sprzęgłem 4-cięgłowym, wykorzystywanym w tramwajach nisko-podłogowych (NGT6-Kr). Przestrzenny model kinematyczny sprzęgła został sformułowany zakładając idealne przeguby i sztywne ogniwa. Równania więzów mechanizmu rozwiązano iteracyjnie, a następnie zróżniczkowano w celu wyznaczenia macierzy jakobianowej mechanizmu. Macierz tą wykorzystano do analizy ruchliwości i osobliwości mechanizmu sprzęgła. Charakterystyki kinematyczne układu z pojedynczym i podwójnym sprzęgłem analizowano w zakresie dużych kątowych i liniowych przemieszczeń wałów układu napędowego. Układ sprzęgłowy oceniano w oparciu o następujące kryteria: homokinetyczność, wyrównoważenie, ograniczenie przestrzeni roboczej oraz dopuszczalne przemieszczenie w przegubach mechanizmu. Analiza parametryczna dotyczyła takich zmiennych konstrukcyjnych, jak: proporcje sprzęgła, przesunięcie i orientacja platform sprzęgieł, czy długość wału pośredniego.

Opis:
Nowadays the demand for renewable energy sources is constantly growing. There are several reasons of such state, including requirements for energy-efficient new buildings and reduction of greenhouse gas emissions. An exemplary solution that may help to reduce “traditional” primary energy consumption is local energy source utilization. The article presents a simplified feasibility study of hybrid energy system under Polish law and economic conditions for a self-government unit, that is legally obliged to apply means of energy efficiency improvement. The aim of this paper is to provide a simple algorithm to find optimal hybrid PV and wind power source sizing for a prosumer. Resource data used in analyses are imported from Photovoltaic Geographical Information System and cover a period of one year. The paper includes two different methodologies applied to solve the problem of optimal hybrid energy system sizing. The first approach is heuristic and based on monthly energy balancing while the second is iterative and takes into account hourly energy balance. The results from both methods are compared and verified by HomerPro software, that shows significant differences between two algorithms. At the end economic assessment based on Net Present Value method is performed.

Opis:
In order to study the effects of various gating systems on the casting of a complex aluminum alloyed multi-way valve body, both software simulation analysis and optimization were carried out. Following, the aluminum alloyed multi-way valve body was cast to check the pouring of the aluminum alloy valve body. The computer simulation results demonstrated that compared to the single side casting mode, the casting method of both sides of the gating system would reduce the filling of the external gas, while the air contact time would be lower. Adversely, due to the pouring on both sides, the melt cannot reach at the same time, leading to the liquid metal speed into the cavity to differ, which affected the liquid metal filling stability. The riser unreasonable setting led to the solidification time extension, resulting in a high amount of casting defects during solidification. Also, both gating systems led the entire casting inconsequential solidification. To overcome the latter problems, a straight gate was set at the middle pouring and the horizontal gate diversion occurred on both sides of pouring, which could provide better casting results for the aluminum alloyed multi-valve body.
