Opis:
Komputerowe programy prezentacyjne oraz łatwe w obsłudze edytory języków programowania stworzyły nauczycielom nieograniczone moŜliwości projektowania i wykonywania własnych opracowań metodycznych opartych na technologiach informatycznych i informacyjnych. Jak wielkie znaczenie cywilizacyjne wywarło upowszechnienie się hiperteksu wyjaśnia szerzej W. Furmanek w opracowaniu Cywilizacyjne i osobowe znaczenie hipertekstu [2008]. W artykule poruszana jest problematyka związana z projektowaniem multimedialnych programów dydaktycznych. To na etapie projektowania podejmowane są decyzje dotyczące struktury programu dydaktycznego, sposobu prezentowania treści kształcenia, ich układu metodycznego, doboru mediów słuŜących do przekazywania i sprawdzania nowo nabytych wiadomości. Często konsekwencją ustalenia struktury multimedialnego programu dydaktycznego i zastosowania określonych mediów jest wybór technologii informatycznych słuŜących do jego realizacji.
Presentation computer programs and easy to use word processors for programming language have offered teachers inexhaustible possibilities of designing and performing their own methodological studies based on information technology. W. Furmanek broadly explains the civilisation significance of popularising a hypertext in the study Civilisation and personal significance of hypertext (2008). The article presents the issues connected with designing multimedia didactic programmes. During the designing stage, there are decisions taken on the structure of a didactic programme, the way of presenting its educational contents, their methodological layout as well as the adjustment of media needed to pass and check newly acquired knowledge. In most cases, the creation of the structure of a multimedia didactic programme and application of specific media relies on the selection of information technologies that allow for its implementation.

Opis:
In this paper an idea of the elastic band method was exploited to design a repeatable inverse kinematics algorithm for robot manipulators. The method incorporates an optimization process at many stages of its performance and admits some extensions. Performance of the algorithm was illustrated on models of the three DOF planar pendulum and the PUMA robot. A comparison with a standard pseudo-inverse Jacobian algorithm, which does not preserve repeatability of inverse kinematics, is also provided.

Opis:
At the beginning we would like to provide a short description of the new theory of learning in the digital age called connectivism. It is the integration of principles explored by the following theories: chaos, network, complexity and self-organization. Next, we describe in short new visual solutions for the teaching of writing so called multimodal literacy 5–11. We define and describe the following notions: multimodal text and original theory so called NOS (non-optimum systems methodology) as a basis for new methods of visual solutions at the classes and audiovisual texts applications. Especially, we would like to emphasize the tremendous usefulness of evolutionary algorithms VEGA and NSGA as tools for optimal planning of multimodal composition in teaching texts. Finally, we give some examples of didactic texts for classrooms, which provide a deep insight into learning skills and tasks needed in the Internet age.

Opis:
Nowadays, scientists may learn a lot about the organisms studied just by analyzing their genetic material. This requires the development of methods of reading genomes with high accuracy. It has become clear that the knowledge of the changes occuring within a viral genome is indispensable for effective fighting of the pathogen. A good example is SARS-CoV, which was a cause of death of many people and frightened the entire world with its fast and hard to prevent propagation. Rapid development of sequencing methods, like shotgun sequencing or sequencing by hybridization (SBH), gives scientists a good tool for reading genomes. However, since sequencing methods can read fragments of up to 1000 bp only, methods for sequence assembling are required in order to read whole genomes. In this paper a new assembling method, based on graph theoretical approach, is presented. The method was tested on SARS-CoV and the results were compared to the outcome of other widely known methods.

Opis:
It is well known that in discrete optimization problems, gradient (local) algorithms do not always guarantee an optimal solution. Therefore, the problem arises of finding the accuracy of the gradient algorithm. This is a fairly well-known problem and numerous publications have been devoted to it. In establishing accuracy, various approaches are used. One of these approaches is to obtain guaranteed estimates of the accuracy of the gradient algorithm in terms of the curvature of the admissible domain. With this approach, it is required to find the curvatures of the admissible region. Since finding the exact value of curvature is a difficult problem to solve, curvature estimates in terms of more or less simply calculated parameters of the problem are relevant. A new improved bound for the curvature of an order-convex set is found and is presented in this paper in terms of the steepness and parameters of strict convexity of the function.

Opis:
The presented paper comes as a summary of a theoretical work presenting an original algorithm describing International Multimodal Transport (IMT) mechanisms and processes. Since containers appeared in early 1960s on the regional, and later on, on global scale in logistic operations, the IMT has become the fastest growing combination of an international through-transport. With use of various modes of transport IMT has significant influence on global trade development. Due to its characteristic the IMT process is exposed on the global unitization, standardization, safety, security and economization (optimization) challenges. Thus, there is a need for scientific approach in building a standardized conceptual model of IMT referred in this paper to CAIMT. CAIMT is an original, deterministic algorithm, presented in the block notation, identifying typical procedures as a logical continuation of the programmed sequence of the basic IMT operations. The suggested CAIMT has a potential in further standardization of IMT procedures and can be scientifically developed through the modeling of the IMT processes and safety/security procedures. In addition, in terms of empirical aspects, algorithmization of the main IMT processes can lead to their application in the various expert systems. Summing up, this method (CAIMT) comes as an optimal instrument that can be utilized in order to build further pillars for IMT development, standardization and optimization.

Opis:
The historical knowledge of Poles, including Polish students, leaves much to be desired, even on a basic level. The insufficient or even the lack of consolidation is the most likely explanation of this phenomenon. The proposed solution to this problem is the SuperMemo and its similar algorithms, along with school history content specially edited for its needs. Basically an algorithm is a set of steps leading to the completion of a task. In the SuperMemo case, the task is to optimize learning, or rather to reduce forgetfulness, while reducing the time devoted to still well-remembered knowledge. Both the SuperMemo and its similar have been implemented in many applications. Quizlet or the software with the same name as the algorithm – SuperMemo, are the examples of such applications. They allow you to learn your own materials as well as those already edited, either by the producer or by other users. The previously edited school historical content for the SuperMemo algorithm and its similar cannot be considered satisfactory if important issues such as: compliance with the core curriculum, division into classes and topics, historical narrative coherence, relationships between pairs of questions and answers, or degrees of difficulty, are regarded. This article proposes a method that can improve this state of affairs. It is the result of theoretical and quasi-experimental work, corrected later on the basis of more serious editorial experience.

Opis:
A collision avoidance algorithm applicable in simultaneous localization and mapping (SLAM) has been developed with a prospect of an on-line application for mobile platforms to search and map the operation area and avoid contact with obstacles. The algorithm, which was implemented in MATLAB software, is based on a linear discrete-time state transition model for determination of the platform position and orientation, and a ‘force’ points method for collision avoidance and definition of the next-step of platform motion. The proposed approach may be incorporated into real-time applications with limited on-board computational resources.

Opis:
Let G = (V,E) be a graph and let k ∈ Z⁺. A total k-subdominating function is a function f: V → {-1,1} such that for at least k vertices v of G, the sum of the function values of f in the open neighborhood of v is positive. The total k-subdomination number of G is the minimum value of f(V) over all total k-subdominating functions f of G where f(V) denotes the sum of the function values assigned to the vertices under f. In this paper, we present a cubic time algorithm to compute the total k-subdomination number of a tree and also show that the associated decision problem is NP-complete for general graphs.

Opis:
As today’s communicative acts are usually irrevocably tied with digital technology, it is important to better understand the resulting ontological and epistemological shifts. The central claim of this article is that humans can no longer be the prime referents of research, either as pure communicators or pure audiences. Instead, research must become sensitive to relational agential flows, whereby different entities interact within ontologically flat agglomerations. For this purpose, the article develops a posthumanist account of the research process that explicitly rejects traditional anthropocentric assumptions in favor of an egalitarian framework that emphasizes relationality and, therefore, constant multidirectional change without linear paths of causation.

The load factor is the determining factor for airlines in economic terms and the prediction of the future development of the flight route. The combination of load factor and break-even point provides the airline with a comprehensive picture of the business of the flight route and the optimization of pricing for the flight route. The purpose of the article is to propose and adapt the development of air transport prices on a given line using maximally recalculated values and maximize profit. The optimized calculation algorithm then facilitates the understanding of the individual steps of the load factor calculation and the monitoring of price development by means of the chi-square mathematical method by which we observed the interconnection of the ticket price and the load factor. To describe the problem, we chose the Bratislava – Larnaca route.
