Opis:
W artykule prezentowane jest podejście metodyczne do prowadzenia kompleksowych analiz na potrzeby polityki i strategicznego zarządzania publicznego. Do identyfikacji podobnych regionów, pomiędzy którymi mogą wystąpić efekty uczenia się, zaproponowano metody taksonomiczne, natomiast metodę delficką wskazano jako odpowiednią dla lepszego zrozumienia przyszłości usług publicznych oraz zwiększenia zdolności adaptacyjnych na różnych poziomach sprawowania władzy. Metody zostały zilustrowane przykładami zastosowań, zaczerpniętymi z dorobku projektu ADAPT2DC („New innovative solutions to adapt governance and management of public infrastructures to demographic change”).
The paper aims at presenting method approach to complex analysis in support of policy making and strategic public management. Taxonomic methods are used to identify similar regions that can benefit of mutual learning and improve their performance in public service delivery. Delphi study is proposed to better understand public service futures and increase adaptation capacities on different levels of governance. The methods are illustrated with samples of ADAPT2DC project („New innovative solutions to adapt governance and management of public infrastructures to demographic change”) works and reflections concerning their application.

Opis:
The subject of the article is the functioning of contemporary young adults in situations subjectively difficult for them. The aim of the research was to reconstruct and analyse the ways of dealing with young adults in situations perceived by them as difficult. The research involved 122 people aged 20–35. The data was collected using a follow-up interview and a questionnaire. The studies were conducted using a research paradigm defining phenomena as a process (a processual approach), revealing its complexity of the phenomenon and internal mechanisms as well as their genesis (analysis aimed at reconstructing the diversity of its internal structure using qualitative analyses and one of the methods of data mining – Quinlan’s C4.5 algorithm). An empirical model was obtained showing the spectrum of ways of coping with difficulties encountered by young people in their everyday life: from (1) withdrawal or submission, or (2) controlling the area of activity by imposing/adopting rules, to (3) going beyond self-protection with minimising failures, or (4) perceiving confrontation with problems as a natural component of life.
Przedmiotem artykułu jest funkcjonowanie współczesnych młodych dorosłych w sytuacjach dla nich subiektywnie trudnych. Celem badań była rekonstrukcja i analiza sposobów radzenia sobie młodych dorosłych w sytuacjach postrzeganych przez nich jako trudne. W badaniach wzięły udział 122 osoby w wieku 20–35 lat. Dane zostały zebrane za pomocą wywiadu podążającego oraz ankiety. Badania przeprowadzono z wykorzystaniem paradygmatu badawczego definiującego zjawisko jako proces (podejście procesualne), ujawniającego jego złożoność i wewnętrzne mechanizmy oraz ich genezę (analiza ukierunkowana na rekonstrukcję różnorodności jego wewnętrznej struktury z wykorzystaniem analiz jakościowych oraz jednej z metod data mining – algorytmu C4.5 Quinlana). Uzyskano model empiryczny ukazujący spektrum sposobów radzenia sobie z trudnościami napotykanymi przez młodych ludzi w codziennym życiu: od (1) wycofania lub podporządkowania się bądź (2) kontrolowania obszaru działania poprzez narzucanie/przyjmowanie reguł do (3) wykroczenia poza ochronę siebie poprzez minimalizowanie niepowodzeń czy (4) postrzegania konfrontacji z problemami jako naturalnego składnika życia.

Opis:
The growing need of ocean surveying and exploration for scientific and industrial application has led to the requirement of routing strategies for ocean vehicles which are optimal in nature. Most of the op-timal path planning for marine vehicles had been conducted offline in a self-made environment. This paper takes into account a practical marine environment, i.e. Portsmouth Harbour, for finding an optimal path in terms of computational time between source and end points on a real time map for an USV. The current study makes use of a grid map generated from original and uses a Dijkstra algorithm to find the shortest path for a single USV. In order to benchmark the study, a path planning study using a well-known local path planning method artificial path planning (APF) has been conducted in a real time marine environment and effectiveness is measured in terms of path length and computational time.

Opis:
The aim of this paper is to investigate dense linear algebra algorithms on shared memory multicore architectures. The design and implementation of a parallel tiled WZ factorization algorithm which can fully exploit such architectures are presented. Three parallel implementations of the algorithm are studied. The first one relies only on exploiting multithreaded BLAS (basic linear algebra subprograms) operations. The second implementation, except for BLAS operations, employs the OpenMP standard to use the loop-level parallelism. The third implementation, except for BLAS operations, employs the OpenMP task directive with the depend clause. We report the computational performance and the speedup of the parallel tiled WZ factorization algorithm on shared memory multicore architectures for dense square diagonally dominant matrices. Then we compare our parallel implementations with the respective LU factorization from a vendor implemented LAPACK library. We also analyze the numerical accuracy. Two of our implementations can be achieved with near maximal theoretical speedup implied by Amdahl’s law.

During investigations of criminal offences of this category it is extremely important for an investigator to have proper access to the scene of an accident and to develop their own algorithm of work. According to the results of our study of the statistical data and materials of criminal proceedings (cases), we have found out that a lot of criminal cases in Ukraine were closed for various reasons for the past three years. In particular, there were registered 88 cases according to the constituent elements of offence, provided for in Art. 276 of the Criminal Code of Ukraine in 2011. There were 5 cases closed by procedure, and 67 ones taken to courts. In 2012, there were registered 53 cases according to the constituent elements of offence, provided for in Art. 276 of the Criminal Code of Ukraine. 13 of them were closed by procedure, and 71 cases were taken to court. And in 2013, the rate got worse since out of 237 registered cases according to the constituent elements of offence, there were 1429 closed by procedure and 11 ones taken to courts. Taking into consideration these data, it is timely and necessary to update scholarly attention to the key aspects of the issues, to develop the mechanism of improving current legislation and the algorithms for the proper functioning of investigators.

Opis:
The article deals with the modified Dijkstra’s algorithm of searching the shortest routes between all transport nodes of the road-transport network, which allows presenting the transport problem in the classical matrix form. This makes it possible to apply each of the known methods of optimal transport plans to solve it. The object of study is the transport process of freight transportation on the transport network by routes of international transport corridors. The purpose of the work is to improve the methods of solving the problems of finding the shortest routes on the transport network, including sections of international transport corridors. The research method is the analysis and modeling of freight transportation on road networks. The modified Dijkstra’s algorithm of finding the shortest paths between all nodes of the road-transport network was work out, which allows to represent the transport problem in the classical matrix form, i.e. in the form of a table of connections. This makes it possible to apply each of the known methods of constructing optimal plans of cargo transportation in the table of connections. The software complex based on the developed algorithm was designed in the algorithmic language Delphi, which was tested on the example of a transport problem set in the form of a road network, as well as complex testing and debugging of a computer system to support decision-making on the optimization of freight traffic on Ukrainian and Western Europe transport systems.

Opis:
It is well known that Weather Routing is one of the effective ship operation methods to reduce fuel consumption and many studies have been conducted to develop the effective calculation methods. However, most studies were performed focusing on the ocean going ships, and there were few studies made for coastal ships. The authors propose a minimum fuel route calculation method for coastal ships that use the precise forecasted environmental data and the propulsion performance data of the ship on actual seas. In the proposed method, we use the Dijkstra’s algorithm to calculate an optimum minimum fuel route suitable for coastal ships. Simulation study was carried out to evaluate the effectiveness of the proposed method using two coastal ships. As the result of study, the authors confirmed that the proposed calculation method is effective for fuel consumption reduction and is applicable for the operation of coastal merchant ships.

Opis:
In this paper we have factorized matrix polynomials into a complete set of spectral factors using a new design algorithm, and with some systematic procedures a complete set of block roots (solvents) have been obtained. The newly developed procedure is just an extension of the (scalar) Horner method to its block form for use in the computation of the block roots of matrix polynomial, the block-Horner method bringing a local iterative nature, faster convergence, nested programmable scheme, needless of any prior knowledge of the matrix polynomial, with the only one inconvenience, which is the strong dependence on the initial guess. In order to avoid this trap, we proposed a combination of two computational procedures, for which the complete program starts with the right block-Q.D. algorithm. It is then followed by a refinement of the right factor by block-Horner’s algorithm. This results in the global nature of the program, which is faster in execution, has well defined initial conditions, and good convergence in much less time.

Opis:
The alleged proof of the non-mechanical, or non-computational, character of the human mind based on Gödel’s incompleteness theorem is revisited. Its history is reviewed. The proof, also known as the Lucas argument and the Penrose argument, is refuted. It is claimed, following Gödel himself and other leading logicians, that antimechanism is not implied by Gödel’s theorems alone. The present paper sets out this refutation in its strongest form, demonstrating general theorems implying the inconsistency of Lucas’s arithmetic and the semantic inadequacy of Penrose’s arithmetic. On the other hand, the limitations to our capacity for mechanizing or programming the mind are also indicated, together with two other corollaries of Gödel’s theorems: that we cannot prove that we are consistent (Gödel’s Unknowability Thesis), and that we cannot fully describe our notion of a natural number.
