Abstract

The Opole region struggles from the most unfavourable demographic situation among all Polish administrative regions. The region is not only losing its population but also reports a growing number of inhabitants aged 50 and more. For this reason, demographic challenges are high on the region’s development agenda. The establishment of the Special Demographic Zone for Opolskie Voivodeship (SDZ) has provided an incentive to take measures, both on the local and regional scale, to reverse the undesirable situation.

This article discusses one of the SDZ packages, namely Package 4 Golden Autumn intended for persons aged 50 and move. Based on surveys held in the municipalities of the Opole region, the author seeks to answer questions related to the perception of the existing demographic processes as developmental barriers and looks at different initiatives and action taken by local self-governments for 50+ residents.

Abstract

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.

Abstract

There is a very high interest in international literature about the governance of common goods related to a redefinition of representative democracy. Scholars like Sheila Foster and Christian Iaione have proposed new models of governance enhancing the preservation and management of the commons in order to overcome problems and contradictions of complex contemporary cities, such as social exclusion and land privatisation. The aim of this paper is to verify, through a recognition of administrative documents, if in the example of Rome, the political actors, the municipal government, and the civil society, could be able to take part in a collaborative governance inspired reform. To answer this question, the relationship between the policy making process, the economic production model and the normative claims arising from social groups will be investigated. What is emerging is a difficulty of the administration in implementing collaborative principles. This is reflected in the issuance of discordant administrative measures, stemming from problems in relaying to civil society and active citizens the role that these principles assign. The reasons for this mismatching might be identified in the distinctive urban regime of Rome and the political and economic set that fosters social exclusion and does not consider the positive effects and the value of collaborative-oriented policy, enhancing sharing economy and social cohesion. The constant recall in the political discourse of concepts such as common goods, citizen’s participation and collaboration values takes the characteristics of a discursive resource, a ‘common washing’, which institutions and politics seem to re-propose and consolidate the traditional mode of public action, though apparently declaring its inadequacy and ineffectiveness.

Abstract

This article sheds light on the advent of online platforms and the way it is reshaping urban enviroment, breaking down traditional axes of both social interaction and commercial power, shifting the structure of traditional services. The platform revolution is radically transforming an array of many functional cities’ areas, like transportation, accommodations and personal services. Thus current concerns as strong urbanization, industrialization and world population growth, enable sharing economy firms to flourish as a reaction against the frictions of urban life exploiting such exacerbation, in order to fulfill demand for appropriate services. After a critical analysis of these issues, the article deepens innovative transportation services, moving on to illustrate the Italian rulemaking process as a chance to provide a solution to the ongoing problem of striking the right balance between competing priorities, such as market access and preservation of sustainable mobility. It suggests to reflect upon the best approach able to face the complexity of urban transport systems, in order to break in a new culture for urban mobility, comply to EU legislation too.

Abstract

A relatively high accuracy and reliability of the Differential GPS system makes the receivers of its signal a very good sensor of a ship position and velocity. Among the input from the gyrocompass, a complete, self-contained and portable ship manoeuvring trial system is obtained. However, the ship instant velocity vector is not measured directly but estimated through the application of the Kalman filter (one of its functions). In case of the ship manoeuvring, this leads to a systematic deviation of such the estimate as compared to the real motion. The magnitude of this bias is being thoroughly investigated for different ship manoeuvres. It appears essential in ship manoeuvring mathematical model identification and/or validation based on full-scale trials.

There are international organizations for preparation variety of standards. In ISO organization TC 211 group elaborates standards for geographic information system creation. Its works are observed by national working groups interested in those topics. European normalization committee CENffC 287 worked about it too. Basing on international standards Polish Standard Committee (PKN) has undertaken works on applicable schemes to standardize notion scheme for data of geographic. In this paper critical opinion of geometric description of geographic data in space scheme spread by PKN on chosen elements of data modelling is presented. It is illustrated by chosen examples of data modeling.

Abstract

This paper proposes a solution to the problem of colour map designing on CRT monitors. Colour progression scales and ranges of constant depth colours are computed using the basic cell of colour processing which is a combination of the new colour appearance model CIECAM02 and the colorimetric model of monitor (Berns' GOG). This paper also presents practical side of designing colour progression scales balanced to constant depth colours, defining parameter of vivid level of projecting scales and showing CIECAM02 model calculation formulas in reverse mode.

Abstract

The paper presents a method of testing trends in spatial distribution of objects and phenomena. which has been called by the author ,,the spatial concentration method". For those fields of knowledge, where information about trends in spatial distribution of phenomena is important, two meanings of the term ,,concentration" arc used. With respect to functionality it means a mechanism of processes, which lead to Ji versification of concentration of tested objects or phenomena in space. With respect to the structural aspect, the term ,.concentration" is understood as description of certain conditions of the tested spatial system, i.e. conditions of higher or lower concentration of the system elements. This paper focuses on concentration with respect to the latter case. The proposed method of spatial concentration is a tool, which allows for wide research investigations. It has been assumed that concentration is specified with respect to a reference function, which is selected according to the objective of investigations. Therefore it is possible to investigate various aspects of trends in distribution of phenomena. It should be stressed that the proposed method is of general nature, in a sense that it also covers other methods of investigations, which have been based on measures of concentration; the proposed method also allows for searching for trends in spatial distribution of phenomena and objects. The algorithm of determination of spatial concentration, presented in a simple form, is the base for software development and for automation of investigations.

Abstract

Surface matching is a fundamental task that must be solved whenever we want to merge data sets of same physical surface obtained with different sources. In general, the points in two sets are in different reference systems, not identical with different accuracy, distribution and density. To perform surface matching the different target functions are proposed. Proposed target function in section 1.4 is based on the condition of equality of triangle areas (TIN). This target function can be used for surface patches of pattern set S 1 generated also in squares (DEM). Conception of target function provided in section 1.5 is based on the combination of two conditions. The first of them is a condition of fitting two normal vectors of surface patches generated by square model (DEM) in set S 1 (as a pattern) and of triangle created with three points in set S2 (as a candidate). The second is one of four target functions upper represented.

Abstract

This paper presents a geeral concept of an adjustment method Edgeworth series applied. The author proposes to replace distributions with approximating functions representd by Edgeworth series, which would be a universal, probabilistic model of the adjustment problem. Special attention is paid to variance an lysis. A con variance matrix C, of the vector X, its estimate C,, and and estimate of the variance coefficient a0 are derived. Also some further properties of the proposed method are presented.

Abstract

Assuming correlation only within the results of measurement repetitions for each quantity observed in a network, equivalence has been proved for two forms of parametric adjustment model, which differ in the approach to measurement repetitions and are called the one-stage and the two-stage model respectively. As a complement to the known criterion of imperceptibility of disturbances in observations, the criterion of imperceptibility of correlation between the components of the observation vector has been formulated, which applies to each of the modules of the two-stage model. Assuming the structure of the observation error, being slightly developed as compared to the standard structure, the cases of meeting of each of the above criteria in those modules have been presented. Then, the relationship which combines measures of internal reliability for both the adjustment models under question has been given.

Abstract

The paper presents an attempt at building an optimum rnathematical model making it possible to prognose the values of missing geodetic surveys of a non-stationary dislocations process within the area of underground exploitation influence. It has been shown thai the analysed process can be assigned 10 the group of stochastic processes. A model (IO) has been determined as the formal definition of the discussed problem, whereas two algorithmic procedures appear to be the real solution. Utility aspect of the paper comprises the modelling of the formation process of actual dislocations. Estimated values of one-stage prognosis are shown in table I and in Fig. 4. Model quality indicator - error distribution - appears to be the confirmation that a quantitative description is adequate to the survey results. It has been shown from the point of view of descriptive statistics, using correlation coefficient, that the results of the dislocations survey of the field points - significantly distant included - are highly correlated.

Abstract

The surface matching is useful to solve the problem of comparing two surfaces obtained from two data sets of the same terrain. The data sets of points could be get from different sources such as Aerial and Satellite imagery, SAR, IFSAR, UDAR etc. The solution of surface matching problem is based on the some characterized contours existed on the surfaces as line features, which have to be expressed by parametric representation in frequency domain. Line features could be determined in the 2-D image or object space. For finding corresponding pair of point belonging to corresponding interest lines on the both surfaces, the image and object line features-based matching method has been used. Surface matching accuracy is estimated basing on the coordinates differences between the original and transformed surfa
