Opis:
The paper focuses on type II Topp-Leone Frechet distribution. Its properties including hazard rate function, reverse hazard rate function, Mills ratio, quantile function and order statistics have been studied. The maximum likelihood estimation used for estimating the parameters of the proposed distribution has been explained and expressions for the Fisher information matrix and confidence intervals have been provided. The paper discusses the applications of the distribution for modeling several datasets relating to temperature. Finally, the goodness of fit of the proposed distribution has been compared with that of the Frechet distribution.

Opis:
The text is concentrated on relations between concepts of privacy and solitude nowadays. The author claimed that privacy replaced traditional metaphors and images of solitude like island, mountain or dessert. Protection of privacy and bringing it to the limelight, privatization of religion and the special place occupied in contemporary culture by a search for one’s own identity reveal not only a change in society’s ideas about privacy, but also its axiotic dimension connected with authenticity, creativity and freedom. The meaningful result of this process is connected with replacing religious Transcendence by private individual internal experience, which became unrecognizedand mysterious for the subject itself. It proved to new conceptualization of privacy and ofsolitude as well.

Opis:
The article seeks to explore the role of Edith Stein’s memory in creating the contemporary identity of the city of Wrocław. The author distinguishes between two forms of this memory, that is to say remembrance and symbolic places (lieux de mémoire). The places of remembrance of Edith Stein, who was born in Breslau, are connected with her biography and the time she spend in this city. The symbolic places of the memory of Edith Stein represent the values of her life (such as the European Peace Cross, meticulously analysed by the author). Both forms of memory variously transformed the space of the city in significant landscape.

Opis:
This article is concerned with the meaning of death in representations of the other world in modern culture. The images of life after death, which are derived from religious traditions, are transformed as a result of the process of desacralization. Changes in the traditional iconography of the other world as well as its new representations in the media and popular culture (particularly in fi lms), can be discussed either in terms of saving the symbolic meaning of death or losing its importance in modern culture. Having studied certain examples, the author concludes that the search for the meaning of death inthe present is less connected with traditional or modern representations of the other worldthen with the human experience.

Opis:
A set D of vertices of a graph G = (VG, EG) is a dominating set of G if every vertex in VG — D is adjacent to at least one vertex in D. The domination number (upper domination number, respectively) of G, denoted by [formula], respectively), is the cardinality of a smallest (largest minimal, respectively) dominating set of G. A subset D ⊆ VG is called a certified dominating set of G if D is a dominating set of G and every vertex in D has either zero or at least two neighbors in VG — D. The cardinality of a smallest (largest minimal, respectively) certified dominating set of G is called the certified (upper certified, respectively) domination number of G and is denoted by [formula]), respectively). In this paper relations between domination, upper domination, certified domination and upper certified domination numbers of a graph are studied.

Opis:
The effect of different methodological steps on the analysis of chlorophyll a (chl a) was tested with algae cultures and Baltic Sea water. Selected experiments were tested with ANOVAs for significant differences between treatments. The results of the experiments led to the following recommendations: the sample volume should be low so that filtration takes no longer than 10 min. Extracts rather than filters should be stored if storage of the samples at −20◦C is required. However, quickfreezing in liquid nitrogen is recommended. The extraction efficiency was much better in 96% ethanol than in 90% acetone – extraction in the latter solvent requires the filters to be homogenised. The extraction time has no significant influence within a range of 3 to 24 hours if the recommended 96% ethanol is used.

Opis:
Polish memory was mainly founded by mythology of Polish romanticism. The way is one of its symbolic form, connecting peoples destiny, national history, catholic faith and landscape of former Eastern Borderlands. The article is devoted to analysis of the way as a memory image of the inhabitants of the Lower Silesia resettled here after the Second World War. It is based on the photos taken by local farmer in late fifties. The author distinguished three symbolic modes of the way as a memory image in particular small village community: axis mundi; passage; pilgrimage. According to him, catholic religion play crucial role in construction of Polish memory and national identity in Lower Silesia after the war.

Opis:
A subset D ⊆ VG is a dominating set of G if every vertex in VG – D has a neighbor in D, while D is a paired-dominating set of G if D is a dominating set and the subgraph induced by D contains a perfect matching. A graph G is a DPDP -graph if it has a pair (D, P) of disjoint sets of vertices of G such that D is a dominating set and P is a paired-dominating set of G. The study of the DPDP -graphs was initiated by Southey and Henning [Cent. Eur. J. Math. 8 (2010) 459–467; J. Comb. Optim. 22 (2011) 217–234]. In this paper, we provide conditions which ensure that a graph is a DPDP -graph. In particular, we characterize the minimal DPDP -graphs.

Opis:
A dominating set of a graph G is a subset D ⊆ VG such that every vertex not in D is adjacent to at least one vertex in D. The cardinality of a smallest dominating set of G, denoted by γ(G), is the domination number of G. The accurate domination number of G, denoted by γa(G), is the cardinality of a smallest set D that is a dominating set of G and no |D|-element subset of VG \ D is a dominating set of G. We study graphs for which the accurate domination number is equal to the domination number. In particular, all trees G for which γa(G) = γ(G) are characterized. Furthermore, we compare the accurate domination number with the domination number of different coronas of a graph.

Opis:
Small autonomous surface vehicles (ASV) will need both teleoperation support and redundant positioning technology to comply with expected future regulations. When at sea, they are limited by a satellite communication link with low throughput. We have designed and implemented a graphical user interface (GUI) for teleoperation using a communication link with low throughput, and one positioning system, independent of the Global Positioning System (GPS), supported by the teleoperation tool. We conducted a user study (N=16), using real-world data from a field trial, to validate our approach, and to compare two variants of the graphical user interface (GUI). The users experienced that the tool gives a good overview, and despite the connection with the low throughput, they managed through the GUI to significantly improve the positioning accuracy.

Opis:
The domination subdivision number sd(G) of a graph G is the minimum number of edges that must be subdivided (where an edge can be subdivided at most once) in order to increase the domination number of G. It has been shown [10] that sd(T) ≤ 3 for any tree T. We prove that the decision problem of the domination subdivision number is NP-complete even for bipartite graphs. For this reason we define the domination multisubdivision number of a nonempty graph G as a minimum positive integer k such that there exists an edge which must be subdivided k times to increase the domination number of G. We show that msd(G) ≤ 3 for any graph G. The domination subdivision number and the domination multisubdivision number of a graph are incomparable in general, but we show that for trees these two parameters are equal. We also determine the domination multisubdivision number for some classes of graphs.
