Opis:
World news coverage is an important source of information about the worlds of “the others” for television audiences. Its production is connected with the hidden logic in the selection of issues, geographical areas, and actors. International news fl ows are infl uenced by news values, cultural and geographical contexts, and historical backgrounds. Th is article presents a study of foreign aff airs coverage in Czech television news programs based on a quantitative content analysis. It deals with questions such as: which countries or continents are included in the television news agendas? What is the frequency of their coverage? How is the news fl ow aff ected by the news values?

Opis:
This article presents an authorial swarm algorithm that performs coverage tasks using the Sweep Coverage method. The presented solution assumes stochastic movement of the objects in the swarm which allows them to be simple ones. Our goal was to find an optimal number of objects in the swarm. The main evaluated factors are time and energy consumption. Changing input data allowed us to designate different cases and to examine the influence of varying parameters of a single boid on a whole swarm behaviour.
W artykule przedstawiono metody znalezienia optymalnej wielkości roju dla danego zadania. Głównymi ocenianymi czynnikami są czas i zużycie energii. Autorskie rozwiązanie algorytmiczne pozwoliło na wyznaczenie różnych przypadków i zbadanie wpływu różnych parametrów pojedynczego boida na zachowanie całego roju. Obliczenie efektywności energetycznej pozwoliło na wyznaczenie dodatkowych informacji o optymalizacji liczby boidów w roju. Wyniki pokazują, że można ocenić najlepsze rozwiązania dla określonych założeń. Można znaleźć, jaka liczba boidów wykonałaby zadanie w jak najkrótszym czasie przy założonej energooszczędności. Można również znaleźć grupę z najlepszym czasem do uzyskania wskaźnika efektywności energetycznej, która wykonałaby zadanie przy najlepszej kombinacji najkrótszego czasu i zużytej energii. Dodatkowe testy ze zmieniającymi się zmiennymi pozwoliły określić ich wpływ na wynik. Wykazano, że prędkość i bezpieczna odległość są ze sobą połączone, ale zmiana prędkości jest bardziej znacząca dla mniejszych rojów, gdy zmiana bezpiecznej odległości ma większy wpływ na liczniejsze grupy. Wynika z tego, że dla małych grup lepsze są szybsze boidy, a dla liczniejszych rojów bardziej przydatne byłyby boidy, które mogą poruszać się bliżej. Zmienianie promienia obszaru skanowanego na każdym kroku wpływa na ogólną wydajność, ale prawie nie ma wpływu na efektywność energetyczną roju.

Sustainable tourism development concept defined by World Tourism Organization reveals a need for common network formation as a platform for cooperation between different tourism sectors and stakeholders. Additional reason for the growing interest in cooperation in tourism is the belief that organisations and destinations may be able to gain competitive advantage by bringing together and sharing their combined knowledge, expertise, financial capital and other resources for common goal. Cooperation networks can gain collaborative advantage not only for separate organisation, but the whole destination. Topicality of the problem is based on the global competition, heterogeneous nature of tourism industry, rapidly developing technological innovation, need for sustainable development set additional importance for cooperation in order to keep pace with the latest developments and new possibilities for cooperation networks. The aim of paper will discuss tourism industry sectorial and regional coverage of tourism associations and other formal networks in Latvia from the perspective of sustainable tourism destination development. Conclusions and suggestions are drawn for overall tourism industry as system development, cooperation network gap reduction by sectors as well as by regions and tourism organisation cooperation improvement in Latvia.

One of the main priorities of emergency services is to minimize the response time to calls. In the process of proper allocation of emergency vehicles, maps of emergency vehicle accessibility are found to be helpful. These maps represent areas within which emergency services can reach the specified location within a certain time. Calculating travel times requires taking into account the rapidly changing current road conditions. This paper presents a method for dynamically generating maps of emergency vehicle accessibility, considering network models and irregular computational grids.

W pracy przedstawiono wyniki badań nierównomierności pokrycia opryskiwanych obiektów przy użyciu rozpylaczy jedno- i dwustrumieniowych. Badania przeprowadzono w warunkach laboratoryjnych, wykorzystując nośnik rozpylaczy. Dla ułatwienia interpretacji wyników badań nierównomierności pokrycia i wykazania istniejących zależności autorzy posłużyli się wskaźnikiem średniego stopnia pokrycia opryskiwanych obiektów, który jest stosunkiem sumarycznego pokrycia poszczególnych opryskiwanych obiektów do ilości tych obiektów. Mimo zastosowania takich samych warunków eksperymentu dla wszystkich badanych rozpylaczy uzyskane wyniki średniego stopnia pokrycia i nierównomierności pokrycia charakteryzowały się dużymi różnicami dla poszczególnych rozpylaczy. Analiza wyników badań nie wykazała istnienia bezpośredniej zależności między średnim stopniem pokrycia opryskiwanych obiektów a współczynnikiem nierównomierności pokrycia. Zarówno w przypadku rozpylaczy jedno-, jak i dwustrumieniowych te, dla których stwierdzono najmniejsze i największe średnie pokrycie, charakteryzowały się podobnym współczynnikiem nierównomierności pokrycia.
The paper presents the results of the studies on the unevenness of covering the sprayed objects with the use of one and double-stream nozzles. Tests were carried out in laboratory conditions with the use of sprayer carrier. In order to facilitate interpretation of the results of studies on unevenness of covering and showing the existing relations, authors used an index of mean degree of the sprayed objects, which is a relation of a total covering of particular sprayed objects with the amount of these objects. Despite the use of the same conditions of experiment for all researched sprayers the obtained results of mean covering and unevenness of covering were characterised with high differences for particular nozzles. Analysis of the research results did not show any direct relation between mean degree of coverage of the sprayed objects and a ratio unevenness of the coverage. Both in case of one and double-stream nozzles, for which the smallest and the biggest coverage was determined, were characterized with a similar ratio unevenness of coverage.

Opis:
In wireless mobile sensor networks, periodic calculation of coverage is very important, since mobile sensors can be moved adequately to current needs, thus increasing the coverage. Those moves require the execution of navigation tasks. Global network central algorithms for those tasks are very costly regarding energy consumption and computational resources. Considerations presented herein pertain to the best algorithms for a network of numerous small mobile sensor nodes used for monitoring of large terrains. Localized algorithms suggested in this paper help calculate the coverage on-line and locally with the involvement of neighboring nodes only. Furthermore, localized collaborative navigation is presented. It enables yielding position estimation with no GPS use and ensures improvement rather than deterioration over time. It uses multi-sensor fusion algorithms based on optimization and a distributed iterative extended Kalman Filter.

Opis:
The article presents results of studies in the area of insurance coverage of farmer population conducted in 2016 in the Szerzyny commune (Malopolska province). The data accumulated through surveys allowed for an assessment of real scope of insurance coverage concerning mandatory and voluntary agricultural insurances. Presented data cover individual kinds of insurances connected with running agricultural farms, including the division of farms according to the farmland area. In the sphere of mandatory insurances, a fact of not fulfilling the obligation of signing insurance contracts has been noted, whereas in case of voluntary insurances, the use of insurance coverage may be stated as marginal. Generally, it may be said that the agricultural insur¬ance market in Poland has faced serious barriers to its development. One of them is the barrier of demand, whose main factors are: the value of property necessary to cover with insurance, insurance awareness, but also a tendency to insure the property according to owner’s financial abilities. The latter factor seems to be the most important.

The problem of covering the area by circles, mathematical model of the coating offers a new coverage criteria based on which analytically describes the range of permissible solutions of the problem. Based on the analysis of the properties of the model, it is shown that the solution of the problem can be reduced to the solution of problems of nonlinear programming sequence. At the moment, there are systems of video monitoring forest land. An important class of geometric design problems is problems of irregular covering the field by geometric objects, as well as regular. In the problems of covering it is set up a claim that all points of the field were covered by geometric objects, while the conditions of non-intersection of objects between themselves and their placement in the field may be violated. One problem with the design of terrestrial video monitoring systems is to optimize the placement of observation points. optimal placement of towers problem can be formulated as a coating task. An approach to the placement of towers terrestrial video monitoring of forest fires, the main stage of which is set forth search method local extremum in the problem coverage area circles of varying radius. There is build a mathematical model to optimize the placement of variable radius circle and on its basis – the development of methods of solution and proposed an approach to obtaining a local extremum of covering problem.

The present part focuses on the characteristics of the participants (parties) in journalistic information. Prevailing and determining factors related to the number and the type of participants in journalistic information are presented, and fundamental functions of speech verbs (verba dicenti) are indicated. Citation is the most explicit form of inclusion of other-discourse in one’s discourse. The second part of the study provides more detailed analysis that includes the following categories: the category of witnesses, experts (practitioners) and that of experts (theoreticians). The third part of the article is due to be published soon.

The major challenge in designing wireless sensor networks (WSNs) is to find tradeoff between the desired and contrary requirements for the lifetime, coverage or cost while coping with the computation, energy and communication constraints. This paper examines the optimal placement of nodes for a WSN. It is impossible to consider the deployment of the nodes separately from WSNs applications. We highlight the properties of WSNs applications that determine the placement problem. We identify and enumerate the various objectives that should be considered. The paper provides an overview and concentrates on multi-objective strategies, their assumptions, optimization problem formulation and results.

Opis:
The new WiMAX technology offers several advantages over the currently available (GSMor UMTS-based) solutions. It is a cost effective, evolving, and robust technology providing quality of service guarantees, high reliability, wide cov- erage and non-line-of-sight (NLOS) transmission capabilities. All these features make it particularly suitable for densely populated urban environments. In this paper we discuss the design and implementation difficulties concerning network coverage discovered in a test-bed implementation of WiMAX. We point out the presence of unexpected "white spots" in the coverage, which are not inherently characteristic of the WiMAX concept. As a possible remedy to this significant drawback of the otherwise very promising technology, we consider reconfigurable mesh organization of WiMAX base stations. We also suggest directions for further development of this kind of network operation, partly based on our practical experience. Despite the clear advantages of the mesh mode in WiMAX networks, its development is currently at an early stage, due to the high complexity of the necessary mechanisms. In this situation, we propose an original, much simpler solution: the so-called support-mesh mode.

We recently noticed increased media coverage of the expression/collocation réfugiés environnementaux. The aforementioned collocation is omnipresent in the French media; it has been circulating and has been in use for over twenty years. However, why has environmental refugee been chosen in English? The main argument is that this expression officially appeared as early as in 1985, in the report for the United Nations Environment Program (UNEP), so it is a UN term. There are currently other names that supplant it: déplacés or migrants; nonetheless, the term réfugié has a much greater impact given the implicity of its meaning. We shall see why the term réfugiés environnementaux/climatiques is in current use and why it is preferred to déplacés and migrants climatiques/environnementaux. The aim of this article is to detail the terms employed expanding on dictionary explanations, as well as to clarify the analysis of the journalistic and legal contexts. To conclude, we shall unveil the terms which seem to us best suited.

Opis:
Six years after the so-called ‘refugee crisis’ in 2015, the European Union remains divided on questions of migration and asylum policy. The issue also remains high on the agendas of the USA and Russia, two other key destination countries with immigration from Latin America and the Post-Soviet space. This article presents results from a comparative study of news coverage in 17 countries, focusing on 10 EU member states in Western and Central Eastern Europe (CEE), the USA and Russia. The intensity of coverage was remarkably different, with Hungary’s and Germany’s media standing out while Russian media displayed relatively low levels of coverage. Individual migrants and refugees were most visible in the two outlets from the USA. Media in CEE countries tended towards a more critical approach than media in Western Europe. However, differences between most countries’ pairs of analyzed media outlets indicate a more pluralistic debate than frequently assumed.

Opis:
This paper examines the relationship between the media coverage of soccer and political popularity of certain parties during election campaigns which usually followed the world soccer games. The national team’s success on the pitch is related to victory in the political match. This surprising link between the national success in sports and the success in an election for a party or a candidate is explained in the light of Public Mood Theory, founded by W. Rahn, who pointed out that emotions play an important role in political behaviour and national identity, which, in turn, is influenced by the media content, like sports coverage among others. The creation of national identity is mostly built on the national success in sports. Especially in Germany, where soccer is number one sport in media coverage. Sports matches produce winners and losers, thus strongly influencing Public Mood, which is relevant for the formation of political evaluations and judgments, in a democracy shaped by emotions. Sports can shape Public Mood only if they are reported in the media. The analysis of the relationship between interest in soccer and political popularity, presented in the paper, shows how the media coverage of soccer influenced the German political attitudes in 2002, to an extent that it might have been decisive for the election.

The purpose of applying an additional air flux in field sprayers is limiting liquid drift. The tlux also influences the quality of plant spraying. Air Plus Spridotrain sprayer, produced by RAU company, was applied in the research on the influence of air flux on the quality of coverage of winter wheat (Roma variety). The plant coverage was determined using water sensitive papers.
Opryskiwacze polowe wyposażane są w rękawy powietrzne w celu zmniejszenia znoszenia cieczy na sąsiednie pola. Zmiana wydatku dodatkowego strumienia powietrza z rękawa ma również wpływ na jakość opryskiwania roślin. Do badań zastosowano opryskiwacz AirPlus firmy RAU wyposażony w rozpylacze wirowe ConeJet TXVK-10. Opryskiwano pszenicę odmiany Roma. Analiza wyników badań wskazuje na wpływ wydatku dodatkowego strumienia powietrza. Im wyższa dawka cieczy na hektar, tym lepsza jakość pokrycia liści pszenicy. Najwyższą wartość stopnia pokrycia powierzchni liści uzyskuje się przy dawce 403 l/ha i średnim ustawieniu wydatku powietrza (ponad 80%).

The control flow of programs can be represented by directed graphs. In this paper we provide a uniform and detailed formal basis for control flow graphs combining known definitions and results with new aspects. Two graph reductions are defined using only syntactical information about the graphs, but no semantical information about the represented programs. We prove some properties of reduced graphs and also about the paths in reduced graphs. Based on graphs, we define statement coverage and branch coverage such that coverage notions correspond to node coverage, and edge coverage, respectively.

Opis:
This paper describes an attempt of implementing physical parameters into a virtual swarm algorithm solution. It defines which physical parameters of the single object need to be known to properly transfer a virtual algorithm into a physical system. Considerations have been based on a stochastic movement swarm performing a coverage task. Time to finish the task and energy consumptions were measured for different numbers of drones in a swarm allowing to designate an optimal size of the swarm. Additional tests for changing variables allowed us to determine their impact on the swarm performance. The presented algorithm is a discrete-time solution, and every test is divided into steps. Positions of the drones are calculated only in time corresponding to these steps. Their position is unknown between these steps and the algorithm does not check if the paths of two drones cross between subsequent positions. The lower the time interval, the more precise results, but simulating the test requires more computing power. Further work should consider the smallest possible time intervals or additional feature to check if the paths of the drones do not cross.
W artykule opisano próbę implementacji parametrów fizycznych do rozwiązania algorytmu wirtualnego roju. Określono, które parametry fizyczne pojedynczego obiektu muszą być znane, aby poprawnie przenieść wirtualny algorytm do systemu fizycznego. Rozważania oparto na stochastycznym roju ruchu wykonującym zadanie przeszukiwania. Zmierzono czas wykonania zadania i zużycie energii dla różnej liczby dronów w roju, co pozwoliło na wyznaczenie optymalnej wielkości roju. Dodatkowe testy zmieniających się zmiennych pozwoliły określić ich wpływ na wydajność roju. Przedstawiony algorytm jest rozwiązaniem dyskretnym i z każdym testem jest podzielony na kroki. Pozycje dronów są obliczane tylko w czasie odpowiadającym tym krokom. Ich pozycja między tymi krokami jest nieznana, a algorytm nie sprawdza, czy ścieżki dwóch dronów przecinają się między kolejnymi pozycjami. Im krótszy odstęp czasu, tym dokładniejsze wyniki, ale symulacja testu wymaga większej mocy obliczeniowej. Dalsze prace powinny uwzględniać możliwie najmniejsze odstępy czasu lub dodatkową funkcję do sprawdzenia jeśli ścieżki dronów się nie przecinają.

Opis:
The role of the public sphere has increasingly come to the fore in studies concerning the state of democracy in Europe. Similarly the role of culture in formations and transformations not only of personal but of political identities as well has attracted attention. It is the purpose of this article to bring these areas together in a comprehensive approach to media, culture and democracy with a view of the public sphere as a crucial mediating field. Article focuses on the role of media in sustaining and developing democracy, a democratic dialogue and in fulfilling the role of media as the critical watchdog of the political system and other powerful players on the European scene. The concept of knowledge democracy is meant to enable a new focus on the relationships between knowledge production and dissemination, the functioning of the media and our democratic institutions. The emerging concept of knowledge democracy moreover obliges us to realise that the institutional frameworks of today’s societies may appear to be deficient as far as the above mentioned undercurrents, trends and other developments demand change. Democracy is without a doubt the most successful governance concept for societies during the last two centuries. It is a strong brand, even used by rulers who do not meet any democratic criterion. Representation gradually became the predominant mechanism by which the population at large, through elections, provides a body with a general authorization to take decisions in all public domains for a certain period of time. Fragmentation of values has lead to individualisation, to uniqueness but thereby also to the impossibility of being represented in a general manner by a single actor such as a member of parliament. More fundamentally media-politics destroy the original meaning of representation.

Opis:
A design of a computational environment for simulation and statistical analysis of shotgun DNA sequencing process is presented. The approach involves developing simulation procedures on the basis of the Lander-Waterman theory. The explored aspects concern numbers of gaps and contigs. Simulations allow drawing certain conclusions: the created model is very similar to the Lander-Waterman theory, simulations of k-mers maps by the Poisson process allows estimating statistics of contigs number.
W artykule zawarte są informacje dotyczące statystycznej analizy metody sekwencjonowania typu „Shotgun”. Projekt zakładał stworzenie środowiska obliczeniowego oraz modelu matematycznego, który jak najdokładniej odzwierciedla proces sekwencjonowania metodą „Shotgun”, wykorzystując przy tym losowe powstawanie krótkich sekwencji nukleotydowych, tak zwanych read’ów, a co za tym idzie również losowe formowanie się contig’ów – w pełni odtworzonych odcinków sekwencji. Stworzony model dzielił sekwencję zasad na zadaną ilość read’ów o stałej długości którą następnie odtwarzał poprzez porównanie końca poprzedniego i początku kolejnego read’a, sprawdzając tym samym ile fragmentów zostaje w pełni złożonych w contig’i. Jako własności statystyczne metody można rozumieć wzory Landera-Watermana przewidujące ilość powstawania contig’ów, które biorą pod uwagę całkowitą ilość read’ów, długość read’ów oraz całą długość sekwencji wejściowej. Wartości uzyskane metodą Landera-Watermana oraz uzyskane za pomocą modelu przedstawiono w postaci wykresu zależności ilości powstających contig’ów do parametru ścieżki pokrycia. Dodatkowo pod względem statystycznym wykreślono histogramy przedstawiające częstość występowania zasad w danym miejscu stworzone w oparciu o model oraz wykreślono na wykresie zakres wyników dla ilości powstających contig’ów wyliczony jako maksima i minima dla wielu losowych prób i przedstawione jako zależność od ścieżki pokrycia.

A simple and efficient method for creating a motion trajectory is presented with an aim to achieve sufficient coverage of a given terrain. A chaotic map has been used in order that the motion trajectory should be unpredictable. The chaotic path generator which has been created, is used for implementing a robot’s movement in four and eight directions. The path generator is tested in various scenarios and the results are discussed. After thorough examination, the proposed method shows that the motion in eight directions gives better and very satisfactory results.

This study concerns the online sports media coverage, a topic that has not been previously analyzed in Poland. In recent decades many studies (in Anglo–Saxon countries in particular) indicated the major underrepresentation of women’s sport and different framing of sportswomen and sportsmen. Those studies showed that the media plays important role in upholding gender stereotypes in sport and hindering empowerment of sportswomen. This study analyzes media coverage of three sports disciplines (gymnastics, swimming and weightlifting) during Rio Olympics on five websites. Findings revealed underrepresentation of women’s sport and setting the trend to write about women’s sport in disciplines consider as appropriated for women. The qualitative analysis did not indicate gender–specific descriptors in materials about sportspeople.

Opis:
Usually, cellular networks are modeled by placing each tier (e.g macro, pico and relay nodes) deterministically on a grid. When calculating the metric performances such as coverage probability, these networks are idealized for not considering the interference. Overcoming such limitation by realistic models is much appreciated. This paper considered two- tier twohop cellular network, each tier is consisting of two-hop relay transmission, relay nodes are relaying the message to the users that are in the cell edge. In addition, the locations of the relays, base stations (BSs), and users nodes are modeled as a point process on the plane to study the two hop downlink performance. Then, we obtain a tractable model for the k-coverage probability for the heterogeneous network consisting of the two-tier network. Stochastic geometry and point process theory have deployed to investigate the proposed two-hop scheme. The obtained results demonstrate the effectiveness and analytical tractability to study the heterogeneous performance.

Opis:
This paper presents the scheme of a software planing tool for single microcells of broadband radio access systems operating at millimeter waves, providing local multipoint distribution services (LMDS), particularly in urban or suburban areas. The aim of this planing tool is to provide operators with information, which supports the assessment of the profitability by calculating link budgets and the area coverage and by roughly estimating the maximum number of potential customers, i.e. the total number of households in a certain area, as well as the number of customers (households) which will actually be covered from a site. A household is here considered as a single apartment or flat, thus a building usually consists of several households. This novel household-estimation model is able to estimate the number of households based only on the 3D-data of buildings, without using residential data. Besides the optimization of line-of-sight (LOS) coverage, also the possibility is considered to enhance the coverage into shadowed areas by using optimized reflectors as passive repeaters up to distances of 1 km from the base station, depending on the system margin and the rain climate zone. All calculations are based on 3D-databases of both, buildings and vegetation.

Opis:
“Patriotic journalism,” a deviation from objectivity, has become an important paradigm and well-documented phenomenon in the analysis of conflict coverage. However, studies rarely focus on the link between journalists’ perceptions and narratives. We investigated how journalists from two countries, one involved in a conflict (Ukraine) and the other observing it from a distance (Sweden) relate to the objectivity norm in sourcing and narrating seven conflictive news cases in Ukraine (2017 to 2018). We found pragmatic commitment to objectivity in both countries, which was not always reflected in the content produced. For Swedish journalists, our results hint toward a value-based ally loyalty, which seems less stable than a tribe-based bond. In Ukraine, official Ukrainian perspectives were undisputedly disseminated; however, we did not find that they were generally positively laden, as one would expect for patriotic journalists. Trust in public institutions might be a deciding factor over the extent of patriotism.

RESEARCH OBJECTIVE: Analysis of how the 2020 US presidential election was covered and framed by Polish television news programs, and whether the polarization of media and politics in Poland was reflected in the studied content, influencing its bias. THE RESEARCH PROBLEM AND METHODS: The analysis of the coverage of the US presidential campaign by three nationwide TV news programs – TVN, TVP and Polsat by using content analysis with elements of framing analysis and comparative analysis. THE PROCESS OF ARGUMENTATION: The article consists of four parts: the first explains the methodology of the study, the second discusses how presidential elections are covered and framed and what influences the national media being interested in covering foreign events. The third part presents the results of the study, and the last contains the discussion and conclusions. RESEARCH RESULTS: The coverage was dichotomous and there was a correlation between the political affiliation of the media and their choice of framing. The media used a combination of game, strategy and conflict framing that highlighted differences between Trump and Biden in terms of the election results and their personal attributes. We found that the electoral rivalry was portrayed as a conflict between the candidates and that the Polish media constructed “enemy” images of candidates and voters depending on their political sympathies. CONCLUSIONS, INNOVATIONS, AND RECOMMENDATIONS: The polarization of media and politics in Poland was reflected in the coverage of the US election. The broadcasters placed Polish political conflicts in the context of the US campaign. It shows that foreign events may be covered by national media through the prism of political bias.

This field has become increasingly more popular in recent times due to the advancement of technology, especially in the fields of miniaturization and telecommunications. The main problem of this research is the relatively untested sensing capability of a mobile wireless sensor network in an operating area that has dis‐ tributed and/or multiple locations of high interest. The purpose of this research is to discover the compatibility of a multiple‐agent coverage control system with several examples of interest functions that have multiple and/or distributed points of global maximum value in order to explore more thoroughly the performance of a given sy‐ stem in a varying environments.

Part Three provides a discussion on and characteristics of the category of the average man in the street, ordinary people whose utterances are increasingly included in the journalistic narration. Taking the notion of everyday life, with which the demand for an ordinary man in the media is closely linked, as a starting point in the discussion, the authors proceed to characterize citations, along with their explanatory attributions, indicate their textual functions and analyse the categories that are revealed within the process: anonymity, transparency and singularity.

Opis:
The paper presents new methods for estimating effective coverage of the image databases in spatial information (SI) vs. colorfulness (CF) space. Existing and commonly used metrics are vulnerable to databases containing very different images in terms of SI and CF, which can maximize the relative ranges, while preserving, in specific cases, high uniformity. The area covered by convex hull created on SI × CF space can be large, but the interior of the convex envelope might be poorly filled. To overcome this flaw, a fill factor is proposed, which determines how well the convex hull area is utilized. In the paper the method is described in details and presented on a few existing databases, as well as on artificial, non-existing databases to prove its robustness in different scenarios. Provided results show that new metric is closer to the actual coverage than existing methods.

The aim of this metric is to show how well the database is filled with variety of images. For each image in the database the Spatial Information (SI) and Colorfulness (CF) metric is calculated. The area of convex hull containing all the points on SI x CF plane is indication of total coverage of the database, but it does not show how efficiently this area is utilized. For this purpose an effective coverage was introduced. An analysis is performed for 16 databases - 13 publicaly available and 3 artificial created for the purpose of showing advantages of the effective coverage.

Opis:
This article analyses the accuracy of the presentation of forests on Polish topographic maps. Four test polygons were selected, differing in forest coverage and spatial distribution of forest areas in order to improve the objectivity of the study. All the polygons were located in Roztocze. Four maps were tested: System 1965 (1:50 000), GUGIK80 (1:100 000), PUWG92 (1:10 000), and VMap L2 (1:50 000). The forest areas from the maps and aerial photographs were vectorised; then the photographs were converted into an orthophotomap that constituted the reference material. All materials were coherent in terms of content validity. After vectorising the range of the forests, sampling was conducted within the hexagonal fields. A comparison of the obtained values provided the basis for maps that presented the errors. The analysis permitted several conclusions to be drawn, generally stating that the credibility of maps within the scope of presenting forest areas depends on the scale and purpose of the map, and that any analyses based on these maps should assume that the results should have higher tolerance levels.

To advance research relating to international confl ict coverage the current study analyzed how Georgian, Russian, and American media framed the 2008 war in Georgia. By examining coverage in Izvestia and Reson- ance as well as Th e New York Times — which is an important example of how the confl ict was presented to the American public — this paper elucidates likely determinants of the type of news and events that are prioritized by media producers proximal to the region of confl ict. We fi nd the similarities in confl ict reporting are as interesting as their diff erences.

The aim of this paper is to analyse the media coverage provided by two Polish daily newspapers (Gazeta Wyborcza and Przegląd Sportowy) during the 2014 Sochi Winter Olympic Games according to the athletes’ gender. The paper makes reference to agenda setting theory and media framing and it is based on an analysis of photographs of the games on the front pages and the sporting articles’ main themes. The analysis reveals that the press focused mainly on the Polish medal winners and did not reveal significant differences between women’s and men’s press coverage. Results show that the discourse of nationalism overrode the discourse of gender, the newspapers’ coverage being mainly based on the success of the Polish athletes, regardless of their gender.

Opis:
Orchards are sprayed at the agro-technical speed ranging from 4 to 6 km per hour. The research paid attention to the influence of a higher speed reaching 8 km/h on the quality of orchard trees spraying. Applying higher speed causes a labour efficiency increase while spraying and reduces time of treatment performance. However, increasing the speed should not decrease the quality of leaf coverage with the sprayed liquid. The results of the carried out research indicate a possibility of increasing the working speed without deteriorating the quality of spraying in dwarf orchards.

Zwiększenie prędkości opryskiwania przy zachowaniu stałych parametrów ciśnienia cieczy i wydatku jednostkowego urządzenia opryskującego spowoduje zmniejszenie dawki cieczy na hektar. W związku z tym należy również sprawdzić jaki jest wpływ niższych dawek cieczy na hektar na jakość opryskiwania drzew. Do opryskiwania sadu jabłoniowego karłowego (odmiana Gloster) zastosowano dwa opryskiwacze sadownicze: Pilmet 1014 Sad and Agrola 1000 eco. Podczas wykonywania zabiegu opryskiwaczem Pilmet stosowano dwie prędkości robocze: 5,0 i 8,3 km/h i trzy dawki cieczy na hektar wynoszące: 260, 322 i 535 I/ha. Przy opryskiwaniu opryskiwaczem Agrola stosowano prędkości 5,1 i 8,2 km/h oraz następujące dawki cieczy: 267, 325 i 541 I/ha. Na rycinie 3 przedstawiono średnie wartości pokrycia liści na całym drzewie i na gruncie pod drzewem dla obu stosowanych opryskiwaczy. Przy średnich wartościach pokrycia zaznaczono przedziały ufności. W przypadku opryskiwania opryskiwaczem Pilmet wartości pokrycia przy stosowanych prędkościach roboczych 5,0 km/ h i 8,3 km/h różnią się istotnie, a przy opryskiwaniu opryskiwaczem Agrola przy prędkościach 5,1 km/h i 8,2 km/h nie różnią się istotnie. W każdym przypadku przy zmniejszonych dawkach cieczy tj. 260 I/ha i 267 I/ha wartości stopnia pokrycia w dalszym ciągu osiągają znaczne wartości, średnio na drzewie dla tych dawek cieczy odpowiednio 34,9% i 33%. Przy opryskiwaniu zbóż przyjmuje się, za wystarczające pokrycie powyżej 15%. Zwiększenie prędkości roboczej do 8 km/h jest celowe, ponieważ osiąga się znaczne zwiększenie efektywnej wydajności powierzchniowej - średnio o 60%.

One in four of all households in Poland does not have access to the Internet, while in the EU15, the same refers to only one in every six households. In this paper we analyze the Internet infrastructure from both supply (broadband coverage-speed) and demand (usage of Internet by individuals-SMEs) side, as well as the affordability aspect. In particular, we search for biggest gaps of Poland’s Internet infrastructure in comparison to other European Union Member States (EU15 and NMS12). Our empirical analysis is based on European Commission’s and ITU’s databases. Moreover, we provide some recommendations for the government and enterprises exposing the biggest gaps of Poland and emphasizing the beneficial impact of the Next Generation Access networks.

Ensuring optimal coverage is a central objective of every sensor deployment plan. Effective monitoring of the environment helps to minimize manpower and time, while enhancing surveillance capability. In this paper, a solution for improved area coverage was presented. A lattice of a pre-defined parameter has been used as an input for the algorithm. For the purpose of the research the blanket deployment strategy has been adopted. Then, a genetic algorithm has been proposed and implemented to find an optimal solution. The proposed approach has been tested and the conclusions have been drawn. The results proved that the proposed genetic algorithm could already provide satisfactory results, usually finding only suboptimal solutions.

Opis:
According to the canons of liberal democracy, both political and media systems constitute two spheres which strongly interact but still are separated and fulfill different aims. The actors belonging to these spheres play specific social roles, due to sets of rules called (respectively) the logic of politics and media logic. Politicians are supposed to create and reshape the world gaining electorate support while the media should show, explain and interpret the world in a way that attracts its audience. The two are expected to compete inside their spheres but not with each other. Today, however, the mediatization of politics and politicization of the media have changed the relationship between politicians and journalists. The aim of the article is to describe the phenomenon of redefinition of roles of the main actors of political communication, using content analysis of television political interviews during an election campaign. Elections create a special situation of mutual interdependence of the two entities as well as the need to achieve their specific goals. The authors weigh up whether the changing formula of TV interviews is an element of a broader phenomenon of competition and trial of taking up control in the process of political communication or just incidental behavior typical for the time of an election.

Opis:
News coverage has a major impact on the interpretation of news events and the response towards these events by public and policy makers. The study intended to investigate the extent of children's rights representation in newspapers in Pakistan. The aim was to determine the coverage, type of the News and level of placement in four selected newspapers (Dawn, The Express Tribune, Jang, and Nawa-i-waqt). A content analysis of 316 news editions of selected samples was conducted over the duration of one year (November 2017 to October 2018). The purpose of content analysis is to provide advocates with a comprehensive basis for how children’s problems are presented in the news. A systematic sampling technique is used for the collection of data. The Nawa-i-waqt newspaper covered the maximum news stories (792 in number) as compared to the other dailies. Furthermore, most of the stories about children were found on the inside pages of newspapers which shows that children’s issues received minimal coverage. This paper argues that the press should take more responsibility by adequately informing children and making them aware, so that the attention of the government and the public can be aimed at tackling child problems in society.

Opis:
In agriculture, the mixing of pesticides in tanks is a common practice. However, it is necessary to previse possible physical-chemical implications of this practice, which may affect the efficiency of the treatments performed. Therefore, the objective of this study was to evaluate the effects of the addition of acaricide to insecticidal spray mixtures on the formation of spray droplets and the interaction with citrus leaves. The experimental design was totally randomized, in a (2 × 3 + 1) factorial scheme for seven treatments. Factor A corresponded to the spray mixture used (isolate or in the mixture). Factor B corresponded to the insecticides tested (lambda-cyhalothrin + thiamethoxam, phosmet, and imidacloprid) and the control consisted of a spray mixture with spirodiclofen only. Nine replications were performed for characterization of the spray droplet size spectrum and four replications for the analysis of the surface tension and the contact angle. The mixture of pesticides showed positive results in terms of application safety. The addition of acaricide to insecticide spray mixtures reduced the surface tension and contact angle of droplets on the adaxial surface of orange leaves. There was an increment in volume median diameter (VMD), a significant reduction in the volume of droplets with drift-sensitive size and improvement in the uniformity of droplet size. Therefore, the addition of acaricide to an insecticide spray mixture positively influenced spray droplet formation and the interaction with citrus leaves providing better coverage and droplet size fractions with an appropriate size for safe and efficient application.

Opis:
Long Range Wide Area Network (LoRaWAN) technology has established new concepts for long-range wireless communication, being widely used in the implementation of IoT solutions. Therefore, it is crucial to validate the coverage of the signal and to know the distance at which a LoRAWAN communication system can be connected. This document investigates LoRaWAN technology for cases based on urban environments, so it can be used as a guide for those projects that require predicting the connection distance range of a LoRaWAN link. In addition, it serves as a tool for the reader when it comes to predicting the coverage of Long-Range Wide Area Network (LoRaWAN) technology. Measurements were made in a LoRaWAN network deployed in urban environments, where RSSI measurements were made in the city of Bogotá D.C., Colombia. Experimentally RSSI values were compared with four different propagation models at a frequency of 915 MHz in urban environments. The contribution of this work is an adjustment to widely used prediction models, according to the recommendation of the International Telecommunications Union (ITU) ITU-R P.1546, which allows estimating coverage in scenarios with characteristics similar to Bogotá D.C. This allows to know with precision the coverage before implementing the LoRaWAN communications system at 915 MHz. The results of comparing field measurements with fitted propagation models show that the Okumura model is the best predictor of coverage with a minimum error rate.

A new over-dispersed discrete probability model is introduced, by compounding the Poisson distribution with the weighted Ishita distribution. The statistical properties of the newly introduced distribution have been derived and discussed. Parameter estimation has been done with the application of the maximum likelihood method of estimation, followed by the Monte Carlo simulation procedure to examine the suitability of the ML estimators. In order to verify the applicability of the proposed distribution, a real-life set of data from the medical field has been analysed for modeling a count dataset representing epileptic seizure counts.

Existence of free media is one of the most important feature of democratic system. Since the collapse of the communist system in 1990s, Central and Eastern European societies have been overtaken by a process of change. Media system change was part of the general process of what may be called systemic social transformation. The main goals of free media in Central and Eastern European were: introduction and legitimization of the concepts of democracy, rule of law and constitutionalism as much as concepts of political pluralism, competition and new political parties and candidates as legitimate competitors. Unfortunately in post-communist countries media have not yet reached a state of full independence from the current interests of political parties. In this study there is case of Poland analyzed. After Polish parliamentary election in 2015 there have been changes in public television. The article presents the results of media content analysis of “Wiadomości” TVP1. In first research there is comparison how “Wiadomości” and “Fakty” coverage the same political events. In second research there is comparison how “Wiadomości” coverage politics in 2015 and after parliamentary election in 2015. The purpose of the research was to evaluate if the politics coverage became more balanced or more biased.

This paper analyses the long-term coverage (1990–2014) of German reunification by six German newspapers. Our quantitative content analysis shows how often the press covers the event, what the content of the coverage is, and how journalists evaluate the reunification process. As we have analysed newspapers of different locations, ranges, types, and editorial lines, we can see whether newspapers cover German reunification differently. Our analysis shows that the amount of coverage of reunification quickly decreases, and only a few articles are published prominently. The press reports on more differences between East and West Germany than similarities; about one third of the articles mentions problems and conflicts, although they become less important over time. All in all, positive evaluations of German reunification outweigh negative judgments and increase over time. We see evidence that the placement, content, and tone of coverage highly depends on the type, editorial line, range, and location of newspapers.

The aim of the study was to analyze the press coverage of sports published in the largest Polish daily newspaper, Gazeta Wyborcza, in terms of gender inequality. The content (both qualitative and quantitative) analysis method was used. In the study, the number of articles on women and men was examined, with the qualitative sections consisting of an analysis of gender stereotypes appearing in these articles. The results demonstrated the underrepresentation of women in the examined sports press coverage. The qualitative analysis showed that articles dealing with women’s sports included gender stereotypes. the articles focused on the physical appearance of women or on their non-sports lives. Infantilizing and marginalizing comments were also present. The study revealed the gender-dependent nature of the press coverage of sports in Poland.

This report looks at the Czech media debate on the European Constitution in the period between French and Dutch “no” to the Treaty Establishing a Constitution for Europe (TCE) and po- litical agreement on the Reform Treaty (June 2005 to June 2007). Based on quantitative and qualitative analyses of the six Czech printed media, the present study confirms that the debate on the European constitution was largely national with overwhelming dominance of Czech actors. The study also indi- cates strong politisation and personalisation of the Czech media debate. The results identify two dom- inant groups of actors and topics in mutual opposition. The first is represented by President Klaus and ODS politicians who oppose the European constitution project. The other group is formed by CSSD politicians and the Chair Jiri Paroubek who support the continutation of the common European Con- stitution project.

Opis:
As day by day the population is increasing, the use of mobile phones and different applications is increasing which requires high data rate for transmission. Homogeneous cellular network cannot fulfill the demand of mobile users, so creating a heterogeneous cellular network (HCN) is a better choice for higher coverage and capacity to fulfil the increasing demand of upcoming 5G and ultra-dense cellular networks. In this research, the impact of antenna heights and gains under varying pico to macro base stations density ratio from 2G to 5G and beyond on two-tier heterogeneous cellular network has been analyzed for obtaining optimum results of coverage and area spectral efficiency. Furthermore, how the association of UEs affects the coverage and ASE while changing the BSs antenna heights and gains has been explored for the two-tier HCN network model. The simulation results show that by considering the maximum macro BS antenna height, pico BS antenna height equal to user equipment (UE) antenna height and unity gains for both macro and pico tiers, the optimum coverage and area spectral efficiency (ASE) for a two-tier fully loaded heterogeneous cellular network can be obtained.
