Opis:
We consider join-semilattices with 1 where for every element p a mapping on the interval [p,1] is defined; these mappings are called sectional mappings and such structures are called semilattices with sectional mappings. We assign to every semilattice with sectional mappings a binary operation which enables us to classify the cases where the sectional mappings are involutions and / or antitone mappings. The paper generalizes results of [3] and [4], and there are also some connections to [1].

Opis:
Cross-border geological mapping is essential for proper understanding of the Poland’s border areas geological setting and their mineral potential. Close co-operation with geological institutions of the neighbouring countries is, therefore, necessary. The joint detailed geological mapping of the cross-border areas was difficult until 1990 because of security reasons. The whole Polish Geological Institute’s mapping activity concentrated, until that time, on very general cartographic presentations of the regional, European or world-wide geology, tectonics, palaeogeography, mineral perspectives, and so on, in the adequately small scales. Since the early 1990s the Institute started to develop more systematic, geophysical, geological and geo-environmental mapping of the common cross-border areas with the national geological surveys and other geological institutions of the neighbouring countries. The most systematic and most detailed cartographic surveys have been carried out so far with the German geological surveys. The Czech, Slovak, and Lithuanian surveys cooperated also very actively. A great cartographic effort has been made on the Baltic Sea geology, as well. Geological mapping co-operation with the Ukrainian, Belarusian, and Russian institution is eventually slowly building up, too. This paper presents the up-to-date results of the joint Polish Geological Institute and the neighbouring geological surveys activities in the geological mapping of the cross-border areas, as well as some current, mapping related activities.

The sales market requires both the highest quality of offered goods and satisfactory prices for the buyer. In addition to the reliability of the important aspects are also the time of order fulfillment, reliability, readiness to act around the clock, and service of sold goods after their sale. In the production and confection of conveyor belts, the priority is a customer who, having strictly defined product requirements, also has individually focused goals. To meet these aspects, you need to look after the product both during its production and after. The products of this industry are specific, so that they can be used, after sales service is often required to be installed at the customer and possible actions to maintain their good condition during operation. The article analyzes selected production processes of transmission belts to identify disturbances. The analysis uses the value stream mapping method. Then, improvement methods were proposed.

Opis:
The protection and preservation of good groundwater quality is of critical importance worldwide, nowadays. Increasing urbanization, economic development and agricultural activities, combined with limited precipitation contribute to the quantitative and qualitative degradation of groundwater resources, especially in the eastern Mediterranean region. For this purpose, a series of actions are implemented including groundwater vulnerability mapping that can depict prone to pollution aquifers which need protection and/or restoration measures. In this study, the efficiency of two well-known methodologies (COP and DRASTIC) for groundwater vulnerability and pollution risk mapping was assessed in the Sperchios river basin. The vulnerability and pollution risk maps of the two methodologies were spatially compared to each other and the observed similarities and differences were discussed and explained. The output of the study shows that in the particular geoenvironmental conditions DRASTIC method performs better than the COP, particularly in the lowland, porous media aquifer.

Opis:
Aerial photographs are a source of geological information that may be unobtainable elsewhere. If the fullest use is to be made of this information for the purpose of geological mapping, there must be a planned integration of the photogeological work with the field and laboratory investigations. The appearance of the first satellites for civil purposes on the beginning of the 1970s (such as ERTS – Landsat series), of most land areas of the Earth has provided new opportunity for photogeologists. Many areas can now be studied and mapped geologically for which neither adequate maps nor vertical aerial photograps were available. The advantages of the present satellite systems and examples of their application by specialists of the Polish Geological Institute are presented in this paper. Nowadays, it is practically impossible to imagine performing geological mapping without application of remote sensing data and analysis. Development of new technologies is very fast and new borne techniques are coming like permanent scatter interferometry, laser scanning etc. However, we should always remember, that they are only very useful tools to help geologists in their field mapping art and practise.

Opis:
Habitat mapping has become an increasingly important application of remote sensing. Active and passive acoustic techniques have greatly improved in the last decade, and their use extends into other spheres to show their economic, legal, political and environmental benefits. This paper reviews the current status of acoustic techniques for habitat mapping. Traditional techniques include echosounders, multibeam systems and sidescan sonars. Passive techniques are also presented, along with geoacoustic inversion and acoustic daylight imaging. The developments in new techniques such as non-linear acoustics, synthetic aperture and interferometry are reviewed. Some emerging techniques are showing increasing potential for habitat mapping, and bistatic sonar, parametric SAS and 3-D chirp profiling are briefly reviewed. Leading international programmes are now making use of these techniques, most often in combination, and their results inform the recommendations for future uses and desired technological developments.

Opis:
It is well known that a power of a right invertible operator is again right invertible, as well as a polynomial in a right invertible operator under appropriate assumptions. However, a linear combination of right invertible operators (in particular, their sum and/or difference) in general is not right invertible. It will be shown how to solve equations with linear combinations of right invertible operators in commutative algebras using properties of logarithmic and antilogarithmic mappings. The used method is, in a sense, a kind of the variables separation method. We shall obtain also an analogue of the classical Fourier method for partial differential equations. Note that the results concerning the Fourier method are proved under weaker assumptions than these obtained in [6] (cf. also [7, 8, 11]).

Opis:
Let X be a Leibniz algebra with unit e, i.e. an algebra with a right invertible linear operator D satisfying the Leibniz condition: D(xy) = xDy + (Dx)y for x,y belonging to the domain of D. If logarithmic mappings exist in X, then cosine and sine elements C(x) and S(x) defined by means of antilogarithmic mappings satisfy the Trigonometric Identity, i.e. $[C(x)]^2 + [S(x)]^2 = e$ whenever x belongs to the domain of these mappings. The following question arises: Do there exist non-Leibniz algebras with logarithms such that the Trigonometric Identity is satisfied? We shall show that in non-Leibniz algebras with logarithms the Trigonometric Identity does not exist. This means that the above question has a negative answer, i.e. the Leibniz condition in algebras with logarithms is a necessary and sufficient condition for the Trigonometric Identity to hold.

Opis:
Nigeria has a vast array of both natural and cultural tourist attractions. The country’s tourism industry, however, remains grossly underdeveloped, and the tourism resources are largely untapped. Hence, the tourism sector of the economy is yet to contribute significantly to the national Gross Domestic Product (GDP). One major factor that is responsible for the nation’s current lacklustre performance of the tourism sector is the poor state of tourism packaging and promotion, which, amongst other things is caused by the lack of appropriate tourist maps. Tourism mapping is a key component of tourism planning, development, promotion and management. For Nigeria to drastically and significantly improve the fortunes of her tourism sector, the production, circulation and use of accurate, current and comprehensive tourist maps and atlases must be vigorously pursued. To ensure sustainable tourism mapping and in line with global best practices, the country needs to adopt a Geoinformation technology-based, Internet-compatible multimedia cartographic approach. The author of this paper, therefore, examines the current state of tourism industry and tourism mapping in Nigeria. Some of the hiccups to tourism mapping in the country are identified. The implications of the present poor state of tourism mapping on tourism planning, development, promotion and management in the country are briefly considered. The author makes a strong case for the adoption of a multimedia cartographic approach to tourism mapping in Nigeria. A case of mapping wildlife parks in Nigeria is presented to demonstrate the prospects of effective multimedia tourism mapping of the country. Furthermore, the author identifies and discusses various existing resources in the country that could be harnessed for efficient and sustainable production, distribution and use of multimedia tourist maps/atlases, using Geographical Information Technologies (GIT). Some potential challenges to effective GIT-based tourism mapping in the country as well as how such challenges could be overcome, are equally discussed. Similarly, a model for Web-based, multimedia tourism mapping using GIT is presented. With clear vision, the right policy instrument, mandate, legislation, funding and coordination in place, the current challenges to effective and sustainable tourism mapping in Nigeria can easily be surmounted.

The paper presents the results of the distribution process analysis based on the well-known visual management tools. This paper presents a logical map of the distribution process and a set of maps resulting from the VSM analysis - Value Stream Mapping. On the basis of a graphical presentation of the distribution process, the number of activities included in the process was determined, the hierarchy of operation execution was identified, relationships between operations were searched, and action providers were identified. However, the most important result of the analysis, was the identification of wastage areas in the process that require improvement.

The security environment is evolving dynamically and analysis of is the task of work security managers. To analyse the security environment we need different data. There are currently online databases published on the publicly accessible data warehouse, as well as web map servers, often in the form of eg. Underlying topographical data used for analysing. Another source of data is the Statistical Office and other authorities or police. Spatial analyses often provide a different view of the monitored phenomenon. Crime mapping is a valuable source of data for the analysis of the security environment. An advantage can be considered the identification of risk areas as well as the monitoring of changes in the extent and location of risk places. The second advantage is the ability to focus only on the analysis of selected offenses that can help, for example, in the monitoring of selected social groups. Crime mapping results are important sources of data for comprehensive analysis of the security environment at the city level. This is confirmed by the results of mapping crime in Kosice for the years 2010 to 2015 presented in this article.

Opis:
Per-pixel extrusion mapping consists of creating a virtual geometry that is stored in a texture over a polygon model without increasing its density. There are four types of extrusion mapping; namely, basic extrusion, outward extru sion, beveled extrusion, and chamfered extrusion. These different techniques produce satisfactory results in the case of plane surfaces; however, when it is about curved surfaces, a silhouette is not visible at the edges of the extruded forms on the 3D surface geometry, as they not take the curvatures of the 3D meshes into account. In this paper, we present an improvement that consists of using curved ray-tracing to correct the silhouette problem by combining per-pixel extrusion-mapping techniques with a quadratic approximation that is computed at each vertex of a 3D mesh.

Opis:
The author presents a geospatial analysis of the Peru-Chile Trench located in the South Pacific Ocean by the Generic Mapping Tool (GMT) scripting toolset used to process and model data sets. The study goal is to perform geomorphological modelling by the comparison of two segments of the trench located in northern (Peruvian) and southern (Chilean) parts. The aim of the study is to perform automatic digitizing profiles using GMT and several scripting modules. Orthogonal cross-section profiles transecting the trench in a perpendicular direction were automatically digitized, and the profiles visualized and compared. The profiles show variations in the geomorphology of the trench in the northern and southern segments. To visualize geological and geophysical settings, a set of the thematic maps was visualized by GMT modules: free-air gravity anomaly, geoid, geology and bathymetry. The results of the descriptive statistical analysis of the bathymetry in both segments show that the most frequent depths for the Peruvian segment of the Peru-Chile Trench range from -4,000 to -4,200 (827 recorded samples) versus the range of -4,500 to -4,700 m for the Peruvian segment (1,410 samples). The Peruvian segment of the trench is deeper and its geomorphology steeper with abrupt slopes compared to the Chilean segment. A comparison of the data distribution for both segments gives the following results. The Peruvian segment has the majority of data (23%) reaching 1,410 (-4,500 m to -4,700 m). This peak shows a steep pattern in data distribution, while other data in the neighbouring diapason are significantly lower: 559 (-4,700 m to -5,000 m) and 807 (-4,200 m to -4,400 m). The Chilean segment has more unified data distribution for depths of -6,000 m to -7,000 m. This paper presents GMT workflow for the cartographic automatic modelling and mapping deep-sea trench geomorphology.

Opis:
Asudeh and Giorgolo (2012) offer an analysis of optional and derived arguments that does away with argument structure as a separate level of representation within the architecture of Lexical Functional Grammar in favour of encoding much of this information in a connected semantic structure. This simplifies the architecture in many ways, but leaves open the question of the mapping between thematic roles, arguments, and grammatical functions (traditionally explored under the umbrella of Lexical Mapping Theory; LMT: Bresnan and Kanerva 1989). In this paper, I offer a formalisation of these mapping relations, drawing on a modern reanalysis of traditional LMT (Kibort 2007), while also continuing Asudeh and Giorgolo’s (2012) quest to evacuate as much information as possible out of individual lexical entries and into cross-categorising templates (Dalrymple et al. 2004; Crouch et al. 2012).

However, representing scenarios is a non-trivial task: (a) multiple aspects of the game need to be visualized; and (b) there is a plethora of representation approaches, out of which the game designer needs to select from. Aim: The goal of this work is to provide a panorama of the current scenario representation approaches, to aid game engineers in selecting the most fitting scenario representation approach and understand the existing designing options. Method: We have performed a Systematic Mapping Study, using 4 digital libraries, since the main goal can be achieved through study classification. By following an established search and filtering process, we have identified 717 articles, and analyzed in detail 95. Results: Diagrams are the most common generic approach to represent scenario; Game story is the most usual part of the scenario being represented; Characters are the most common component; and Transitions are the most usual connectors. Conclusion: Researchers may get useful information for empirically investigating several game engineering aspects; whereas game engineers can efficiently select the most fitting approach.

Opis:
The paper presents the review of mapping techniques applied in research using mental maps. The review covers both evaluative and structural mapping. The choice of a method is influenced by the level of freedom given to the respondents while creating sketch maps. It is also highly aefcted by the area of a given region, scale used in the research and limitations of mapping techniques in GIS software. For large scale maps created in GIS software, it is possible to use quantitative methods, i.e. proportional symbol maps or quantitative signature symbols. Using multiple complementary mapping techniques allows to draw the most comprehensive conclusions in the analyses of perception of a given space in the society.

One of the effects of the exponential growth universally available computing power is decrease of the hardware cost especially multimedia components. This trend combined with integration of image acquisition hardware for multimedia applications for personal computers, enable to create new kind of vision systems - stereovision. The system presented on this paper using two synchronized cameras with USB type interface. In order to obtain an exact copy of the object in 3D type space is necessary to gather the Information about projected points of the space onto the more than one image. The paper is focus on double camera stereovision system and calibration problem with image rectification. The target was achieved with use open source Computer Vision libraries and toolboxes. Practical implementation of presented basic stereovision system (based on two cameras) is addressed for transportation devices which are operating in fixed 3D type space and include for example: device movement trajectory controlling, possible events detecting and worh space of materia handling devices modeling. Paper contains the following key chapters: cameras calibration problem short discussion, single camera calibration approach, and stereovision system architecture and calibration approach.

Opis:
Traditionally, the term mobile mapping refers to a means of collecting geospatial data using mapping sensors that are mounted on a mobile platform. Historically, this process was mainly driven by the need for highway infrastructure mapping and transportation corridor inventories. However, the recent advances in mapping sensor and telecommunication technologies create the opportunity that, completely new, emergent application areas of mobile mapping to evolve rapidly. This article examines the potential of mobile mapping technology (MMT) in sports science and in particular in competitive rowing. Notably, in this study the concept definition of mobile mapping somehow differs from the traditional one in a way that, the end result is not relevant to the geospatial information acquired as the moving platform travels in space. In contrast, the interest is placed on the moving platform (rowing boat) itself and on the various subsystems which are also in continuous motion. As an initial step of an on-going research this article discusses the biomechanics of rowing in relation to applied technique and equipment. Also, it reviews the current practices and sensor systems used for monitoring and evaluating performance in rowing. Finally, it presents an integrated data acquisition and processing scheme for rowing based on modern MMT. To this effect, a critical assessment of the various types of sensors as well as their installation and integration into a recording system is detailed. This analysis benefits by a number of preliminary tests using real data recordings. The boat kinematics (velocity, acceleration and attitude), techniques for their noise elimination and processes for computing average stroke characteristics are studied thoroughly. Also, the pattern of motion in rowing (stroke cycle) is examined in relation to athlete technique and capacity.

Opis:
The purpose of the paper is the identification and description of factors affecting the process of sacralisation as well as the implementation of theoretical concepts in a case study of the Baltic city of Gdynia. The time range of the research is limited to the postwar period (1945–2013). It has been assumed that the formation of any religious landscape occurs under two main circumstances: (1) the need to express faith and (2) the opportunity to do it. The former is an internal factor and depends on religiosity, while the latter is closely related to politics, environment, economy and social life. A detailed scheme was constructed around this statement in the form of a mapping sentence. The research is based on qualitative measures which include field observation, analysis of source documents, and an analysis and criticism of bibliographic sources. Visual documentation and participant observation have also been used. There are two main conclusions coming out of this paper. Although any religious landscape is a mixture of different factors, by the 1980s the sacralisation of Gdynia was determined mainly by political factors, and later by economic and cultural ones. Furthermore, for three decades some tendencies, typical also for the whole country, have also been recognised in Gdynia: monumentalism, privatisation of sacred sites and the “John-Paul-the-Second-isation” of public spaces.

Considering all drawbacks and pluses of ultrasonic sensors, we present an innovative mapping approach, applying the Otsu’s method and Hit-or-Miss for sonar-data processing. The collected data are treated as a gray-scale picture. For its binarization, we applied the well-known for vision-based systems threshold calculation. Then also the morphology effect, what rises additionally the mapping accuracy, as is shown at the end of the paper. The robot is based on the education construction set LEGO Mindstorms EV3 intelligent brick on ev3dev - a Debian Linux-based operating system and Python 2.0 have been used for programming. The results are evaluated and compared with the real space.

Bessaga and Pełczyński showed that if $c_0$ embeds in the dual $X^*$ of a Banach space X, then $ℓ^1$ embeds as a complemented subspace of X. Pełczyński proved that every infinite-dimensional closed linear subspace of $ℓ^1$ contains a copy of $ℓ^1$ that is complemented in $ℓ^1$. Later, Kadec and Pełczyński proved that every non-reflexive closed linear subspace of $L^1 [0,1]$ contains a copy of $ℓ^1$ that is complemented in $L^1 [0,1]$. In this note a traditional sliding hump argument is used to establish a simple mapping property of $c_0$ which simultaneously yields extensions of the preceding theorems as corollaries. Additional classical mapping properties of $c_0$ are briefly discussed and applications are given.

Opis:
The present age of digital subsurface mapping is represented above all by quantitative maps based on regular grids. They are created on the basis of various input data: digitized contours, widely comprehended well data, 2D and 3D seismic, and qualitative geological maps. Scope and the data utilization and the applied methodology of processing are strictly dependent on the scale and purpose of a given map; for regional and detailed maps they are significantly different. However, irrespective of the map scale, correct models, reflecting probable subsurface variability, instead of the input data spatial distribution and applied estimation algorithm themselves, are conditioned by chances of integrating of all the mentioned types of data. These purposes can be achieved only through the application of the most flexible interpretive programs such as ZMAP–Plus or mapping modules of the Geographix system. High quality quantitative subsurface maps based on regular grids are nowadays used first of all in petroleum exploration and geothermal research. But development of such studies may contribute to creation of high-quality, interactive, subsurface models, available not only for owners of expensive professional software but also for all geoscientists interested in these topics.

Bluetooth beacons are becoming increasingly popular for various applications such as marketing or indoor navigation. However, designing a proper beacon installation requires knowledge of the possible sources of interference in the target environment. While theoretically beacon signal strength should decay linearly with log distance, on-site measurements usually reveal that noise from objects such as Wi-Fi networks operating in the vicinity significantly alters the expected signal range. The paper presents a novel mobile Geographic Information System for measurement, mapping and local as well as online storage of Bluetooth beacon signal strength in semireal time. For the purpose of on-site geovisual analysis of the signal, the application integrates a dedicated interpolation algorithm optimized for low-power devices. The paper discusses the performance and quality of the mapping algorithms in several different test environments.

With the increasing uses of internet technologies in daily life, vulnerability of personal data/information is also increasing. Performing secure communication over the channel which is insecure has always been a problem because of speedy development of various technologies. Encryption scheme provides secrecy to data by enabling only authorized user to access it. In the proposed paper, we present an encryption algorithm designed for data security based on bilinear mapping and prove it secure by providing its security theoretical proof against adaptive chosen cipher-text attack. With the help of a lemma, we have shown that no polynomially bounded adversary has non-negligible advantage in the challenging game. We also give the comparative analysis of the proposed scheme in terms of security and performance with Deng et al., 2020 and Jiang et al., 2021 schemes and prove that proposed algorithm is more efficient and secure than others existing in literature against adaptive chosen cipher-text attack.

We prove a basic property of continuous multilinear mappings between topological vector spaces, from which we derive an easy proof of the fact that a multilinear mapping (and a polynomial) between topological vector spaces is weakly continuous on weakly bounded sets if and only if it is weakly uniformly} continuous on weakly bounded sets. This result was obtained in 1983 by Aron, Hervés and Valdivia for polynomials between Banach spaces, and it also holds if the weak topology is replaced by a coarser one. However, we show that it need not be true for a stronger topology, thus answering a question raised by Aron. As an application of the first result, we prove that a holomorphic mapping ƒ between complex Banach spaces is weakly uniformly continuous on bounded subsets if and only if it admits a factorization of the form f = g∘S, where S is a compact operator and g a holomorphic mapping.

Opis:
Nowadays, Multimedia Communication has improved rapidly to allow people to communicate via the Internet. However, Internet users cannot communicate with each other unless they use the same chatting applications since each chatting application uses a certain signaling protocol to make the media call. The mapping architecture is a very critical issue since it solves the communication problems between any two protocols, as well as it enables people around the world to make a voice/video call even if they use different chatting applications. Providing the interoperability between different signaling protocols and multimedia applications takes the advantages of more than one protocol. Many mapping architectures have been proposed to ease exchanging the media between at least two users without facing any difficulties such as SIP-Jingle, IAX-RSW, H.323-MGCP, etc. However, the design of any of the existing mapping architectures has some weaknesses related to larger delay, time consuming, and security matters. The only way to overcome these problems is to propose an efficient mapping architecture. This paper proposed a new mapping architecture between Inter-Asterisk eXchange Protocol and Jingle Protocol. The proposed mapping architecture consists of IAX domain (IAX client, IAX server, IAX-to-Jingle gateway), and Jingle domain (Jingle client, Jingle server, Jingle-to-IAX gateway). The tasks of the translation gateways are represented by the URI conversion, media capability exchange, translator of call setup and teardown signals, and real time media transmission.

Science mapping or bibliometric mapping is a spatial repre-sentation of how disciplines, fields, specialties, and individual documents or authors are related to one another (Small, 1999). Different approaches have been developed to extract networks using the selected units of analysis (authors, documents, journals, terms, etc.). Furthermore, the authors looks at the most popular computer programs used for the processing of bibliographic and biblio-metric data.. In addition, plans and activities are presented concerning a comprehensive analysis of IRNet project (www.irnet.us.edu.pl) networking activities and numerous publications, using spe-cial ICT tools and study methods, first of all Pajek and presenting a several examples.

In this paper, we present the streamed photon mapping method for enhancing the rendering of caustics. In order to achieve a realistic caustic effect, global illumination methods require additional data, which are gathered by creating a caustic map or increasing the number of samples used for rendering. Our method employs a stream of photons with a varying luminance level depending on the material properties of the surface. The application of a concentrated photon stream provides the ability to render caustics effectively without increasing the number of photons in a photon map. Such an approach increases visibility of results, while also allowing for faster computations.

Opis:
Several methods have been proposed in the literature to address the problem of automatic mapping by a robot using range scan data, under localization uncertainty. Most scan matching methods rely on the minimization of the matching error among individual range scans. However, uncertainty in sensor data often leads to erroneous matching, hard to cope with in a purely automatic approach. This paper proposes a semi-automatic approach, denoted interactive mapping, involving a human operator in the process of detecting and correcting erroneous matches. Instead of allowing the operator complete freedom in correcting the matching in a frame by frame basis, the proposed method facilitates the adjustment along the directions with more ambiguity, while constraining the others. Experimental results using LIDAR data are presented to validate empirically the approach, together with a preliminary user study to evaluate the benefits of the approach.
