SAFETY OF CRITICAL INFRASTRUCTURES - CHOSEN MODELING STUDIES OF ENERGY INFRASTRUCTURE ELEMENTS / BEZPIECZEŃSTWO INFRASTRUKTURY KRYTYCZNEJ – WYBRANE BADANIA MODELOWE ELEMENTÓW INFRASTRUKTURY ENERGETYCZNEJ
Authors: Jerzy Małachowski , Tadeusz Niezgoda 
Published: February 2014

Abstract
This research has been inspired by security concerns due to the recent increase in the terrorist threat to gas and crude oil transportation around the world, especially in regions that are of significant value for the energy supplies. Computational mechanics methods will be used in this research to apply shock wave analysis for possible damage assessment of the affected pipelines. These methods may be also used for pipelines at power plants, which are usually placed high on the homeland security priority list. This study is primarily focused on the behaviour of some type of pipeline elements existing in gas pipeline system which can be subjected to the shock wave produced by the detonation of highly explosive (HE) materials. In this kind of studies the numerical coupling procedure describing interaction between gas and solid domain was implemented. Outcomes of this research are very important in preventing damage progression of pipelines under the blast loading.

Published: February 2014

Abstract
The design and construction of a diagnostic device requires the development of a system for the acquisition and processing of measurement data, numerous cable connections and an on-board computer. The key component of a diagnostic system was the Fujitsu FUTRO S100 on-board computer in shock and vibration-proof housing, with passive cooling and a 16 GB Compact Flash memory card. The computer was provided with a NVOX LCD 10” VGA/FVAT touch screen. The following software was used: Windows XP-2000, USB/DeviceNet interface module and a diagnostic program. The computer was connected to the I-7565USB/DeviceNet master device via the USB port. The CAN bus connected the interface module with three slave devices collecting data from sensors installed in various locations of a wheeled tractor.
The Carathéodory topology for multiply connected domains II
Authors: Comerford Mark 
Published: February 2014

Abstract
We continue our exposition concerning the Carathéodory topology for multiply connected domains which we began in [Comerford M., The Carathéodory topology for multiply connected domains I, Cent. Eur. J. Math., 2013, 11(2), 322–340] by introducing the notion of boundedness for a family of pointed domains of the same connectivity. The limit of a convergent sequence of n-connected domains which is bounded in this sense is again n-connected and will satisfy the same bounds. We prove a result which establishes several equivalent conditions for boundedness. This allows us to extend the notions of convergence and equicontinuity to families of functions defined on varying domains.
Boundary vs. interior conditions associated with weighted composition operators
Authors: Izuchi Kei , Izuchi Yuko , Ohno Shûichi 
Published: February 2014

Abstract
Associated with some properties of weighted composition operators on the spaces of bounded harmonic and analytic functions on the open unit disk $$\mathbb{D}$$, we obtain conditions in terms of behavior of weight functions and analytic self-maps on the interior $$\mathbb{D}$$ and on the boundary $$\partial \mathbb{D}$$ respectively. We give direct proofs of the equivalence of these interior and boundary conditions. Furthermore we give another proof of the estimate for the essential norm of the difference of weighted composition operators.

AbstractWe use time-dependent density functional theory and Born-Oppenheimer molecular dynamics methods to investigate the fragmentation of doubly ionized uracil in gas phase. Different initial electronic excited states of the dication are obtained by removing electrons from different inner-shell orbitals of the neutral species. We show that shape-equivalent orbitals lead to very different fragmentation patterns revealing the importance of the intramolecular chemical environment. The results are in good agreement with ionion coincidence measurements of uracil collision with 100 keV protons.
A Jacobi collocation approximation for nonlinear coupled viscous Burgers’ equation
Authors: Doha Eid , Bhrawy Ali , Abdelkawy Mohamed , Hafez Ramy 
Published: February 2014

AbstractThis article presents a numerical approximation of the initial-boundary nonlinear coupled viscous Burgers’ equation based on spectral methods. A Jacobi-Gauss-Lobatto collocation (J-GL-C) scheme in combination with the implicit Runge-Kutta-Nyström (IRKN) scheme are employed to obtain highly accurate approximations to the mentioned problem. This J-GL-C method, based on Jacobi polynomials and Gauss-Lobatto quadrature integration, reduces solving the nonlinear coupled viscous Burgers’ equation to a system of nonlinear ordinary differential equation which is far easier to solve. The given examples show, by selecting relatively few J-GL-C points, the accuracy of the approximations and the utility of the approach over other analytical or numerical methods. The illustrative examples demonstrate the accuracy, efficiency, and versatility of the proposed algorithm.
Surveillance of Vrancea active seismic region in Romania through time series satellite data
Authors: Zoran Maria , Savastru Roxana , Savastru Dan 
Published: February 2014

Abstract
Cumulative stress energy in active seismic regions caused by tectonic forces creates various earthquake precursors. This energy transformation may result in enhanced transient thermal infrared (TIR) emission, which can be detected through satellites equipped with thermal sensors like MODIS (Terra/Aqua) and AVHRR (NOAA). Satellite time-series data, coupled with ground based observations, where available, can enable scientists to survey pre-earthquake signals in the areas of strong tectonic activity. This paper presents observations made using time series MODIS and NOAA-AVHRR satellite data for derived multi-parameters including land surface temperature (LST), outgoing long-wave radiation (OLR), and mean air temperature (AT) for the moderate, 5.9 magnitude earthquake, which took place on the 27th of October, 2004, inthe seismic region of Vrancea, in Romania. Anomalous thermal infrared signals, reflected by a rise of several degrees celsius (°C) in LSTs, and higher OLR values were seen several days before the earthquake. AT values in the epicentral area also increased almost two days prior to the earthquake and intensified three days after the main shock. Increases in LSTs and OLR disappeared three days after the main shock. The survey and joint analysis of geospatial and in-situ geophysical information on land surface temperatures and outgoing long-wave radiation provides new insights into the field of seismic hazard assessment in Vrancea, a significant area of tectonic activity in Romania and Europe.
SOME REMARKS ON PERMUTATIONS WHICH PRESERVE THE WEIGHTED DENSITY
Authors: Paštéka Milan , Václavíková Zuzana 
Published: February 2014

ABSTRACT
In this paper we study the conditions (1), (2) and (3) for the permutations which preserve the weighted density. These conditions are motivated by the conditions of Lévy group, originated in [Levy, P.: Problèmes concrets d’Analyse Fonctionelle. Gauthier Villars, Paris, 1951], and studied in [Obata, N.: Density of natural numbers and Lévy group, J. Number Theory 30 (1988), 288-297]. In the second part we prove that under some conditions for the sequence of weights, for instance for the logarithmic density, the first two conditions can be launched

ABSTRACT
We define uniform distribution in compact metric space with respect to the Buck’s measure density originated in [Buck, R. C.: The measure theoretic approach to density, Amer. J. Math. 68 (1946), 560-580]. Weyl’s criterion is derived. This leads to an existence result.

Authors: Kovalevskaya Ella 
Published: February 2014

ABSTRACT
An analogue of the convergence part of Khintchine’s theorem (1924) for simultaneous approximation of integral polynomials at the points (x1, x2, z,w) ∈ R2 × C × Qp is proved. It is a solution of the more general problem than Sprindźuk's problem (1980) in the ring of adeles. We use a new form of the essential and nonessential domain methods in metric theory of Diophantine approximation
ROTATIONAL CRYPTANALYSIS OF GOST WITH IDENTICAL S-BOXES
Authors: Zajac Pavol , Ondroš Michal 
Published: February 2014

ABSTRACT
Rotational cryptanalysis was introduced by Khovratovich and Nikoli ´c as a tool to analyse ARX-type cipher designs. GOST 28147-89 is a former Soviet Union cipher standard based on a Feistel construction with 32 rounds. Each round function adds the round key modulo 232, transforms the result with 4-to-4 bit S-boxes, and rotates the output. We apply the rotational cryptanalysis to a version of GOST using eight identical S-boxes, such as GOST-PS. We show the existence of (practical) rotational distinguisher in related key model for full GOST. Furthermore, there is a set of weak keys (rotationally symmetric keys) that enables rotational attacks in single-key model as well. Finally, we show a simple attack on the last round that uses the rotational distinguisher to reduce the complexity of the full GOST to 208 bits.
LOW DATA COMPLEXITY DIFFERENTIAL - ALGEBRAIC ATTACK ON REDUCED ROUND DES
Authors: Gąsecki Arkadiusz 
Published: February 2014

ABSTRACT
At IMA 2007 Courtois and Bard presented low-data complexity attacks 011 up to 6 rounds of DES bv software algebraic attack methods and SAT solvers. With current methods it appears that 8 rounds of DES should be able to resist such attacks [Courtois, N. T. Gawinecki, A. Song, G.: Contradiction immunity and guess-then-determine attacks on GOST, Tatra Mt. Math. Publ. 53 (2012), 65 79|. An explicit challenge with a price was proposed: break 8 rounds of DES in less than a week 011 one PC with maximum 2 gigabytes of RAM and given at most 16 chosen plaintexts. In this paper we propose a new attack which is trying to achieve this objective as much as possible. Presented method combines two, already known techniques, namely differential cryptanalysis and algebraic attacks. More specifically, it shows how to use relations arising from differential chracteristics to speed up and im- prove key-recovery algebraic attacks against reduced block cipher DES.
STEGANOGRAPHIC FILE SYSTEM BASED ON JPEG FILES
Authors: Jókay Matúš , Košdy Martin 
Published: February 2014

ABSTRACTA steganographic system provides a hidden communication channel in background of a public channel. The existence of the hidden channel must remain secret, i.e. the adversary cannot decide whether the public channel contains any covert information or not. The public channel that is used in construction of a steganographic system can often be embedded in a static file (medium), that is called a carrier (if the steganographic information is present). Most of the current research focuses on a single medium. The most suitable types of media, such as images or music files, contain a lot of redundancy. Small changes in the redundant parts are not easily detected. However, new methods for the detection of this information are developed along with the new algorithms for embedding the hidden information. Our work describes a new steganographic system design, where the hidden information is spread among many static images in a form of a virtual steganographic filesystem. We note that the implementation of the system must also take into account “steganographic side-channels”, i.e., some information channels that are present in the operating system (in our case Linux, and Android) that leak information about the presence of the hidden channel.
A NOTE ON “ON CIPHERTEXT UNDETECTABILITY”
Authors: Das Angsuman , Adhikari Avishek 
Published: February 2014

ABSTRACT
The notion of ciphertext undetectability was introduced in [Gaˇzi, P. - Stanek, M.: On ciphertext undetectability, Tatra Mt. Math. Publ. 41 (2008), 133-151] as a steganographic property of an encryption scheme. While finding the relationship between ciphertext undetectability and indistinguishability of encryptions, authors showed that ciphertext undetectability does not imply indistinguishability. Though the proposition is correct, the proof is not. In this note, we provide a correct proof of the above-mentioned result by a slight modification of the construction used in original paper cited above.
Poza wspólną historią. Historycznoliterackie uwagi na mar ginesieemigracyjnej polonistycznej dydaktyki / BEYOND COMMON HISTORY: THE DIDACTICS OF POLISH STUDIES ABROAD FROM THE PERSPECTIVE OF A HISTORIAN OF POLISH LITERATURE
Authors: Karwowska Bożena 
Published: February 2014

Summary
Teaching Polish literature in translation at the University in Vancouver constitutes for the author a point of departure for deliberations on the cultural history of Polish literature. Teaching students of various cultural backgrounds make the author realize the inadequacy of many notions of posteolonial discourses in reference to Polish culture. Despite entering into incessant dialogues with the culture of the so called West, Polish literature is nevertheless marginalized by the West; as such, imperialistic discourse does not constitute for it an appropriate reference in educational practices aimed at international students. Didactic solutions based on appeals to processes of familiarizing Poles with their own history and literature (and national values transmitted by them) despite the censorship of the Polish People’s Republic provide a guidance to study of (inter)relationships between literature, culture, and politics and their roles in building a national “structures of feelings”.
DIALOG Z HUMANIZMEM RENESANSOWYM W DZIEŁACH PIOTRA SKARGI / PIOTR SKARGA’S DIALOGUE WITH RENAISSANCE HUMANISM
Authors: Nowicka -Jeżowa Alina 
Published: February 2014

Summary
The article tries to outline the position of Piotr Skarga in the Jesuit debates about the legacy of humanist Renaissance. The author argues that Skarga was fully committed to the adaptation of humanist and even medieval ideas into the revitalized post-Tridentine Catholicism. Skarga’s aim was to reformulate the humanist worldview, its idea of man, system of values and political views so that they would fit the doctrine of the Roman Catholic church. In effect, though, it meant supplanting the pluralist and open humanist culture by a construct as solidly Catholic as possible. He sifted through, verified, and re-interpreted the humanist material: as a result the humanist myth of the City of the Sun was eclipsed by reminders of the transience of all earthly goods and pursuits; elements of the Greek and Roman tradition were reconnected with the authoritative Biblical account of world history; and man was reinscribed into the theocentric perspective. Skarga brought back the dogmas of the original sin and sanctifying grace, reiterated the importance of asceticism and self-discipline, redefined the ideas of human dignity and freedom, and, in consequence, came up with a clear-cut, integrist view of the meaning and goal of the good life as well as the proper mission of the citizen and the nation. The polemical edge of Piotr Skarga’s cultural project was aimed both at Protestantism and the Erasmian tendency within the Catholic church. While strongly coloured by the Ignatian spirituality with its insistence on rigorous discipline, a sense of responsibility for the lives of other people and the culture of the community, and a commitment to the heroic ideal of a miles Christi, taking headon the challenges of the flesh, the world, Satan, and the enemies of the patria and the Church, it also went a long way to adapt the Jesuit model to Poland’s socio-cultural conditions and the mentality of its inhabitants.
PERSPEKTYWIZM W PISARSTWIE STEFANA FLUKOWSKIEGO / STEFAN FLUKOWSKI’S PERSPECTIVISM
Authors: Wojda Dorota 
Published: February 2014

Summary
The work of Stefan Flukowski can be seen as an embodiment of modern perspectivism, a poetics that has spread across virtually all genres and stylistic forms. Its most characteristic techniques are shifts of the narrative point of view, juxtaposition of opposed views and attitudes, the exposure of the inherent complexity of characters and situations, and the colliding of different languages in order to catch glimpses of a reality beyond language. As plenty of those devices can be found in Flukowski’s dramas, poems and fiction, we may conclude that his literary work, which exhibits a remarkable programmatic consistency, situates him on the blurred borderline between the avantgarde and modernism.
