It also discusses ways to control the microclimate and other aspects of the building so as to obtain the maximum comfort of the people placed in them. Considering its high popularity, the smart installation based on the KNX/EIB standard is further discussed, examples of algorithms for dealing with security threats are given as well as the functions indicated which can improve the comfort of using a facility.
The interdisciplinary report is an effect of the work of a team of experts appointed by Division I for Humanities and Social Sciences, Polish Academy of Sciences (PAN). The team consisted of representatives of academic committees of the division. Its task was to formulate answers to 20 questions most frequently asked in public discourse regarding costs and benefits of the European integration, relations between Poland and the EU authorities, threats to the integration, the future of the EU and the place of Poland in the Community. The authors express concern about the potential results of the negative attitude of the current Polish government towards the actions of the institutions of the EU, the growing criticism towards the European integration and the threat of marginalisation of Poland within the EU or even the possibility of Poland’s leaving the EU (Polexit). They also indicate the possible economic, political and civilizational outcomes of the actions of the Polish authorities which weaken Poland’s ties to the EU. The report urges the academic community to increase their research activity and involvement in the public debate regarding these vital issues.
The author presents the search for the identity of individuals and families displaced after World War II from Vilnius to Gdańsk in the context of the urban community integration. Gdańsk being a city where the population after the war was almost fully replaced, becomes in this sense a kind of laboratory of social integration processes. The text serves as an introduction to the topic and is based on the results of the pilot qualitative research conducted within the The Common Room Gdańsk” (2013–2015) project coordinated by prof. M. Mendel. The analyses are a contribution to the reflection on identity determinants of integration processes within the urban community, also in relation to contemporary times. When discussing the issues of identity, the author points to the importance of the turning point which was the end of World War II, and the experience of expatriation in the spatial and socio-cultural context.
Today’s cities tend to “pour out” beyond their administrative boundaries. This phenomenon is related to the settlement of people “from the city” in neighboring municipalities, or taking up jobs in cities by people living in neighboring municipalities. This has been recognized in the European Union, which has introduced appropriate legal instruments for cohesion policy. Integrated Territorial Investments were introduced to the EU cohesion policy for the fi rst time in the 2014-2020 fi nancial perspective. Their goal was to intensify cooperation between cities and their functional areas. Unfortunately, the emerging information about diffi culties in implementing ITIs often become the basis for considering this idea ineff ective. The purpose of the work is qualitative and quantitative verifi cation of the operation of ITU based on selected data, so that it is possible to answer the question about the validity of the existence of this instrument.
The article reviews the integrated territorial investments carried out in the Opolskie Voivodeship in the financial perspective 2014-2020. The object of the analysis was the Opole Agglomeration as the only of five functional areas of the Opolskie Voivodeship, where beneficiaries of funds from European Funds are located within this investment policy development policy.
The aim of the article is to present international economic integration as one of the mega trends that infl uence on the redefi nition of the factors of socio-economic development. The research procedure includes three stages. In the fi rst stage, the most important modern mega trends of socio-economic changes are organized in a synthetic way. In the second step, the genesis and changes of the process of international economic integration are elaborated. In the third stage, the infl uence of international economic integration on the changes of factors of socio-economic development is systematized. This study is being carried out as part of the FORSED research project (http://www.forsed.amu.edu.pl) fi nanced by the National Science Center as part of OPUS competition 10 – 2015/19/B/HS5/00012: New challenges of regional policy in shaping the socio-economic development factors of less developed regions.
The article presents Model Integration of Immigrants in Gdańsk in the field of education, based on two years of experience of schools, local government institutions and social organizations involved in the creation of conditions for the education of immigrants. & e foreign pupils, defined as “someone else”, not belonging to the community of “our”, are not the subject of educational policy, but immediately a} er crossing the threshold of schools become its object. The law and school practices define their place in the system, that becomes a huge challenge for both teachers and for students themselves and their parents. Gdańsk way to develop urban educational policy for immigrants led from intervention by the diagnosis of problems and learning from others, to seek their own innovative solutions.
Baltic Europe, i.e. the sea and inland hinterland, form a unique macro-regional unit. Strong collaboration links as well as competition in the Baltic Sea Region are an inherent feature of the region from the beginnings of its civilization development. The article shows the forty-year-long Baltic integration process and the Polish scientific contribution to the process. Since 2004, the Baltic has become an internal EU sea. This fact no doubt strengthened cooperation of the countries around the Baltic Sea. In many spheres, these ties take the form of networking. An important stimulus for further integrations is the EU Strategy for the Baltic Sea Region. Political stabilisation and economic development may transform, in a longer time span, the emerging transnational Baltic Europe into a new economic and cultural European centre.
Development and demography of Adalia decempunctata L. were studied under laboratory conditions at seven constant temperatures (12, 16, 20, 24, 28, 32 and 36°C). First instar larvae failed to develop to second instar at 12°С and no development occurred at 36°C. The total developmental time varied from 47.92 days at 16°C to 15.94 days at 28°C and increased at 32°C. The lower temperature thresholds of 11.05 and 9.90°C, and thermal constants of 290.84 day-degree and 326.34 day-degree were estimated by traditional and Ikemoto-Takai linear models, respectively. The lower temperature threshold (Tmin) values estimated by Analytis, Briere-1, Briere-2 and Lactin-2 for total immature stages were 11.99, 12.24, 10.30 and 10.8°C, respectively. The estimated fastest developmental temperatures (Tfast) by the Analytis, Briere-1, Briere-2 and Lactin-2 for overall immature stages development of A. decempunctata were 31.5, 31.1, 30.7 and 31.7°C, respectively. Analytis, Briere-1, Briere-2 and Lactin-2 measured the upper temperature threshold (Tmax) at 33.14, 36.65, 32.75 and 32.61°C. The age-stage specific survival rate (sxj) curves clearly depicted the highest and lowest survival rates at 16 and 32°C for males and females. The age-specific fecundity (mx) curves revealed higher fecundity rate when fed A. gossypii at 24 and 28°C. The highest and lowest values of intrinsic rate of increase (r) were observed at 28 and 16°C (0.1945 d–1 and 0.0592 d–1, respectively). Also, the trend of changes in the finite rate of increase (λ) was analogous with intrinsic rate of increase. The longest and shortest mean generation time (T) was observed at 16 and 28°C, respectively and the highest net reproductive rates (R0) was estimated at 24 and 28°C. According to the results, the most suitable temperature seems to be 28°C due to the shortest developmental time, highest survival rate, and highest intrinsic rate of increase.
The aim of the study is to compare the development of self-esteem and identity integration over time among people with disability and without it (data from norm groups), including people with a spinal cord injury as well as with disabilities caused by other reasons. The research examined self-esteem and identity integration of individuals with disability with regard to disability duration, gender, age, correlation analysis of self-esteem and identity integration. The sample consisted of 133 individuals with acquired disabilities. The study used the Polish adaptations of Rosenberg Self-Esteem Scale and Multidimensional Self-Assessment Inventory. Additionally, the respondents with disability completed a form with questions about their age, gender, disability duration and its cause. The outcomes of SES and MSEI modules were checked against the norm groups. The results demonstrated that self-esteem and identity integration do not vary with regard to gender, age or acquired disability conditions. The differences between subjects with disability and the normalized group have proven to be negligible. However, the factor that turned out to be highly significant was the disability duration. Differences have been observed among groups with disability lasting up to 4 months, from 4 months to 2 years, from 2 to 6 years and over 6 years. To sum up, self-esteem and identity integration correlation proved to be high and positive. These findings suggested that the higher the self-esteem, the more integrated the identity, regardless of either the disability type or its degree. The level of self-esteem is subject to differentiation primarily due to disability duration.
The paper presents local dynamic approach to integration of an ensemble of predictors. The classical fusing of many predictor results takes into account all units and takes the weighted average of the results of all units forming the ensemble. This paper proposes different approach. The prediction of time series for the next day is done here by only one member of an ensemble, which was the best in the learning stage for the input vector, closest to the input data actually applied. Thanks to such arrangement we avoid the situation in which the worst unit reduces the accuracy of the whole ensemble. This way we obtain an increased level of statistical forecasting accuracy, since each task is performed by the best suited predictor. Moreover, such arrangement of integration allows for using units of very different quality without decreasing the quality of final prediction. The numerical experiments performed for forecasting the next input, the average PM10 pollution and forecasting the 24-element vector of hourly load of the power system have confirmed the superiority of the presented approach. All quality measures of forecast have been significantly improved.
The article presents a framework for integrating historical sources with elements of the geographical space recorded in unique cartographic materials. The aim of the project was to elaborate a method of integrating spatial data sources that would facilitate studying and presenting the phenomena of economic history. The proposed methodology for multimedia integration of old materials made it possible to demonstrate the successive stages of the transformation which was characteristic of the 19th-century space. The point of reference for this process of integrating information was topographic maps from the first half of the 19th century, while the research area comprised the castle complex in Kórnik together with the small town – the pre-industrial landscape in Wielkopolska (Greater Poland). On the basis of map and plan transformation, graphic processing of the scans of old drawings, texture mapping of the facades of historic buildings, and a 360° panorama, the source material collected was integrated. The final product was a few-minute-long video, composed of nine sequences. It captures the changing form of the castle building together with its facades, the castle park, and its further topographic and urban surroundings, since the beginning of the 19th century till the present day. For a topographic map sheet dating back to the first half of the 19th century, in which the hachuring method had been used to present land relief, a terrain model was generated. The transition from parallel to bird’s-eye-view perspective served to demonstrate the distinctive character of the pre-industrial landscape.
The paper investigates the possibility of utilisation of heat-recirculating systems for fuel conversions having low net thermal effect. The experimental part is conducted with an electrically heated heat exchanger. It is shown that heat-recirculating systems can operate under superadiabatic conditions. Their thermal characteristics are provided by means of the dependencies of heat recirculation ratio on process parameters. Further, the heat-recirculating catalytic combustion system is characterised via combustion bifurcation diagrams. The similarities and differences of both those heat-recirculating systems are qualitatively compared and explained. Bifurcation characteristics proves to be useful tools in concise description of practical complex heat-recirculating fuel conversion systems in energy generation.
This paper estimates the magnitude of the Baumol-Bowen and Balassa-Samuleson effects in the Polish economy. The purpose of the analysis is to establish to what extent the differential price dynamics in Poland and in the euro area and the real appreciation of PLN against EUR are explained by the differential in respective productivity dynamics. The historical contribution of the Baumol-Bowen effect to Polish inflation rate is estimated at 0.9 − 1.0 percentage points in the short run. According to estimation results, the Balassa-Samuelson effect contributed around 0.9 to 1.0 percentage point per annum to the rate of relative price growth between Poland and the euro area and 1.0 to 1.2 p.p. to real exchange rate appreciation. The long-run effects are of an approximately twice larger magnitude. Sub-sample calculations and productivity trends over the last decade suggest that this impact should be declining. However, its size is still non-negligible for policymakers in the context of euro adoption in Poland.
Rescheduling is a frequently used reactive strategy in order to limit the effects of disruptions on throughput times in multi-stage production processes. However, organizational deficits often cause delays in the information on disruptions, so rescheduling cannot limit disruption effects on throughput times optimally. Our approach strives for an investigation of possible performance improvements in multi-stage production processes enabled by realtime rescheduling in the event of disruptions. We developed a methodology whereby we could measure these possible performance improvements. For this purpose, we created and implemented a simulation model of a multi-stage production process. We defined system parameters and varied factors according to our experiment design, such as information delay, lot sizes and disruption durations. The simulation results were plotted and evaluated using DoE methodology. Dependent on the factor settings, we were able to prove large improvements by real-time rescheduling regarding the absorption of disruption effects in our experiments.
The Integrated Psychosocial Model of Criminal Social Identity (IPM-CSI) explains the underlying reasons, i.e. risk factors, for the development of criminal social identity (CSI). Empirical research surrounding these risk factors is inconsistent in the measures and procedures used and the risk factors were mostly considered in isolation from one another. The main purpose of the paper was to review existing empirical studies elucidating correlates of CSI incorporated in the IPM-CSI and indicate further direction for research. A search in PubMed, PsychInfo, ERIC, Google Scholar, and the journal Child Development and Adolescent Studies was performed. Eleven studies exploring the correlates of CSI were identified and discussed herein. Studies indicated that there is potential for further expansion of the IPM-CSI to consider the consequences of CSI. Based on the present study results, a set of recommendations are provided for future research.
The article discusses selected issues concerning both the activities and the contents of Strategy Cracow 2030 – An Ambitious Plan of the City Where Life Can Be Enjoyed. The author analyses how selected concepts well known in the local and regional development policy literature and practice such as territorial capital, second-tier city, integrated territorial planning and metropolisation are refl ected in the key development planning document of the second-largest Polish city. The strategy was adopted by the City Council in February 2018. The article focuses in particular on the applied work method, based on an advanced partnership and cooperation of key stakeholders, assumptions adopted in the strategy and axiology, identified challenges and development resources, and metropolitan city aspirations. The author also discusses selected issues regarding implementation system of the strategy.
Scientists around the world agree that nowadays, science is facing severe challenges like poor peer-review system, replicability crisis, or locked science behind paywalls. The National Science Center addresses at least some of them by introducing procedures that promote integrity, ethics, social responsibility, transparency, and openness in science.
The article presents the question of solidarity in relation to the energy policy of the European Union. This topic seems particularly important in the context of the crisis of the European integration process, which includes, in particular, economic problems, the migration crisis and the withdrawal of the United Kingdom from the European Union (Brexit). The issue of solidarity was analyzed from the legal and formal, institutional, and functional and relational points of view. The aim of the article is to show to what extent the theoretical assumptions, resulting from the provisions of European law on the solidarity, correspond with the actions of the Member States in the energy sector. The practice of the integration process indicates that the particular national economic interests in the energy sector are more important for the Member States than working towards European solidarity. Meanwhile, without a sense of responsibility for the pan-European interest, it is not possible to effectively implement the EU’s energy policy. The European Commission – as the guardian of the treaties – confronts the Member States with ambitious challenges to be undertaken “in the spirit of solidarity”. In the verbal sphere, this is supported by by capitals of the individual countries, but in practice, the actions taken divide the Member States into opposing camps instead of building a sense of the European energy community. This applies in particular to such issues as: the management of the energy union, investments in the gas sector (e.g. Nord Stream I and Nord Stream II), and the position towards third countries – suppliers of energy raw materials to the EU (in particular towards the Russian Federation). Different views on the above problems make it extremely difficult for Member States to take action “in the spirit of energy solidarity”. Thus, the energy problem becomes another reason for the weakening of European unity.
The dynamic development of wind power in recent years has generated the demand for production forecasting tools in wind farms. The data obtained from mathematical models is useful both for wind farm owners and distribution and transmission system operators. The predictions of production allow the wind farm operator to control the operation of the turbine in real time or plan future repairs and maintenance work in the long run. In turn, the results of the forecasting model allow the transmission system operator to plan the operation of the power system and to decide whether to reduce the load of conventional power plants or to start the reserve units. The presented article is a review of the currently applied methods of wind power generation forecasting. Due to the nature of the input data, physical and statistical methods are distinguished. The physical approach is based on the use of data related to atmospheric conditions, terrain, and wind farm characteristics. It is usually based on numerical weather prediction models (NWP). In turn, the statistical approach uses historical data sets to determine the dependence of output variables on input parameters. However, the most favorable, from the point of view of the quality of the results, are models that use hybrid approaches. Determining the best model turns out to be a complicated task, because its usefulness depends on many factors. The applied model may be highly accurate under given conditions, but it may be completely unsuitable for another wind farm.
This study presents cause-effect dependencies between inputs and outputs of business transitions that are software objects designed for processing information-decision state variables in integrated enterprise process control (EntPC) systems. Business transitions are elementary components of controlling units in enterprise processes that have been defined as self-controlling, generalized business processes, which may serve not only as business processes but also as business systems or their roles. Business events, which have zero durations by definition, are interpreted as executions of business actions that are main operations of business transitions. Any ordered set of business actions, performed in the controlling unit of a given enterprise process and attributed to the same discrete-time instant, is referred to as ‘the information-decision process’. The i-d processes may be substituted by managerial business processes, performed on the lower organizational level, where durations of activity executions are greater than zero, but discrete-time periods are considerably shorter. In such a case, procedures of business actions are performed by corresponding activities of managerial processes, but on the level of business transitions the durations of their executions are imperceptible, and many different business events may occur at the same discrete-time instant. It has been demonstrated in the paper how to control business actions to ensure that a given i-d state variable may not change more than once at a given instant. Furthermore, the rules of designing the i-d process structures, which prevent random changes of transitory states, have been presented.
The aim of this paper is to analyze various CO2 compression processes for post-combustion CO2 capture applications for 900 MW pulverized coal-fired power plant. Different thermodynamically feasible CO2 compression systems will be identified and their energy consumption quantified. A detailed thermodynamic analysis examines methods used to minimize the power penalty to the producer through integrated, low-power compression concepts. The goal of the present research is to reduce this penalty through an analysis of different compression concepts, and a possibility of capturing the heat of compression and converting it to useful energy for use elsewhere in the plant.
