Network Actual Traffic Prediction Algorithm Based on α-stable Distribution and Wavelet Transformation
Authors: Chen Guobin , Luo Nanying 
Published: May 2015

Abstract
In order to improve the prediction precision of wireless sensor network traffic, a new prediction algorithm (State Prediction algorithm based on α-stable distribution α, SP-α) is proposed, combined with α-stable distribution and wavelet transformation. The algorithm proposed first defines the characteristics of α-stable distribution and then gives the judge basis that obeys α-stable distribution. At the same time, it reduces the prediction error of the actual traffic by fusion of the prediction results of α-stable distribution with wavelet transformation. Finally, the paper thoroughly researches the key factors impacting on the new algorithm through simulations in OPNET and MATLAB. Compared with the performance of FARIMA model, the simulation results proved that SP-α algorithm has better adaptability.
A Distributed Adaptive Neuro-Fuzzy Network for Chaotic Time Series Prediction
Authors: Terziyska Margarita 
Published: May 2015

Abstract
In this paper a Distributed Adaptive Neuro-Fuzzy Architecture (DANFA) model with a second order Takagi-Sugeno inference mechanism is presented. The proposed approach is based on the simple idea to reduce the number of the fuzzy rules and the computational load, when modeling nonlinear systems. As a learning procedure for the designed structure a two-step gradient descent algorithm with a fixed learning rate is used. To demonstrate the potentials of the selected approach, simulation experiments with two benchmark chaotic time systems − Mackey-Glass and Rossler are studied. The results obtained show an accurate model performance with a minimal prediction error.

Abstract
In this paper, the evolution of the style of Caravaggio had been traced and, focusing on the selected images it had been proved that the methods used by that eminent painter can successfully be applied during the creation of modern, effective multimedia presentations. The strength of Caravaggio was in its simplicity and mundane. For indicated formal measures may be included, inter alia: the elimination of tonally extended second plan and replace it with a dark, uniform background. Caravaggio calmed down composition painting almost monochromatic paintings, which emphasizes the foreground, as well as the keynote message. In the paper it was emphasized that exactly the same objectives should be guided in the creation of multimedia presentations, extracted from unnecessary embellishments that irrupt to the fore dispersing attention. Based on the analysis of selected paintings, in the article, review of procedures associated with the colors of multimedia presentations, extremely important in creating multimedia presentations and highlighting media had been proposed. Several theories related to the psychology of color had been also presented, and also sought to answer the question of why we should not trust psychologists boundlessly.
Development of an Exterior-Mount Real Time Sugar Beet Yield Monitoring System for a Sugar Beet Harvester
Authors: Bagherpour H. , Minaei S. , Abdollahian Noghabi M. , Khorasani Fardavani M. Esmail 
Published: May 2015

Abstract
The main priorities in crop production are increasing the yield and decreasing the cost of production. Precision farming is the best practice to approach these goals. For real time measurement of sugar beet yield, a yield monitor was developed, and installed on the exterior side of the harvester’s chassis. The advantage of this arrangement over similar systems is the location of the load cell and system’s frame which prevents blockage by trash, mud or plant roots. For measurement of weight, one load cell on each side of the harvester chassis was used. Conveyor and ground speeds were measured using two proximity sensors. Because vibrations of the harvester can affect the output signals, it is necessary to find the main bandwidth associated with the weights moving on the conveyor. For this purpose, three different masses were placed on the moving conveyor and this bandwidth was determined using signal processing. Then, a suitable filter was designed and undesirable frequencies acting as noise were attenuated. After calibrating all the sensors, final evaluation of the system was performed in the field and the mean and standard deviation of error were 6.48% and 1.52, respectively. Although the error may seem to be somewhat high but the low of standard deviation indicates that there is a similar error in all tests. These negative errors indicate that the weight is systematically overestimated by the monitor. Thus, the error can be reduced by minor changes in conveyor shape or modified by software means. By software modification, the systematic error was alleviated. The median sugar beet yield was thus obtained to be 42.7 t/ha. Comparing this with the actual mean yield of 41.8 t/ha, it differs by only about 2%.
Banach algebra of the Fourier multipliers on weighted Banach function spaces
Authors: Karlovich Alexei 
Published: May 2015

AbstractLet MX,w(ℝ) denote the algebra of the Fourier multipliers on a separable weighted Banach function
space X(ℝ,w).We prove that if the Cauchy singular integral operator S is bounded on X(ℝ, w), thenMX,w(ℝ)
is continuously embedded into L∞(ℝ). An important consequence of the continuous embedding MX,w(ℝ) ⊂
L∞(ℝ) is that MX,w(ℝ) is a Banach algebra.
Towards a Numerical Model of Bacterial Filtration in Fibrous Filters
Authors: Gac Jakub M. , Gradoń Leon 
Published: May 2015

Abstract
A model of bacterial filtration on fibrous filter media is developed. The single fibre efficiency as well as the efficiency of the whole filter - at the onset of the process and the evolution of those quantities - are analysed. The differences between the numerical modelling of colloidal particles and bacteria are stressed in detail. The main differences are the active motion ability of bacteria and biofilm formation. The parameters of the model were identified based on the literature data.
Ethnic conflict in the so-called Presevo Valley. The role of the Orhodox Christianity/ Konflikt etniczny w tzw. Dolinie Preszewa. Rola religii prawosławnej w konflikcie
Authors: Zenderowski Radosław , Wiśniewski Rafał 
Published: May 2015

AbstractThe aim of this paper is to determine the role of the Orthodox Christianity in the ethnic Serbian- Albanian conflict in the so-called Presevo Valley. This conflict between ethnically and religiously divided societies escalated to a military phase at the turn of the 20th century. The data on the role of the Orthodox Christianity in the conflict and the perception of its characteristics by local Serbs was acquired through the field research conducted in September 2011. The paper is divided into four sections. The first section includes a general description of the Serbian-Albanian conflict in the so-called Presevo Valley; the second part consists of a theoretical framework of the role of religion in ethnic conflicts; the third section contains a field research methodology; and the fourth, main part consists of the analysis of the field data. The analysis of the acquired data was organised in four thematic streams: (a) the defensive character of the Orthodox religion, (b) the Serbian Orthodox Church as a national and religious institution, (c) the perception of local and newcomer Muslims, (d) the perception of the role of religion and other factors in the local ethnic conflict.The conclusion coming from this article is that the religion plays a negligible role in the discussed conflict which was mostly influenced by economic and ideological factors. However, religion can be cleverly instrumentalised in a conflict. Additionally, on the Serbian side, there is visible an increased victimisation discourse (where Serbs are the victims) containing both national and religious motives.

Shareholding Structure and Dividend Policy as Exemplified by the Stock-listed Industrial Companies
Authors: Gawryś Iwona 
Published: May 2015

AbstractThis article is aimed at evaluating the influence of the forms of controlling stock-listed companies upon the decisions being taken in regard of the distribution of profits and the payout of dividends in the unstable macro-economic environment. The form of the ownership supervision reflects the relations between shareholders and managers of the company. The conflicts resulting from the separation of ownership and management of a company concern, among others, the dividend payout. The dividend constitutes a shareholder’s reward for rendering his capital available to the company, while for a company it is a cost in the form of the capital’s reduction and the limitation of investing abilities. Whereas the macro-economic environment influences the financial standing of companies and their profits, which are then used for paying out dividends, and simultaneously defines the investment needs of companies. A hypothesis can be put forward that the economic slowdown limits the access to attractive investment projects, which results in companies being interested in the payout of relatively high dividends. This hypothesis is verifiable on the ground of the decisions taken in regard of the distribution of the profit made by the stock-listed companies of the processing industry between 2007 and 2012.

Equity Investments vs. Debt Investments – What Drives OFDI in Polish Industry
Authors: Kłysik-Uryszek Agnieszka 
Published: May 2015

AbstractPolish economy witnessed enormous changes over the past 25 years. Systematic economic growth, increasing market openness, legal stabilization and integration with EU have substantially improved Poland’s global competitive position. That is reflected, among others, in intensified flows of long-term capital in the form of foreign direct investment (FDI). What is worth stressing, the last decade (regardless the economic crisis) brought a significant rise of investments made by Polish companies abroad (Outward FDI). It should be mentioned however, that the FDI flows are usually analyzed (in both theoretical and empirical literature) as if they consist only of equity investments, when in fact they consist also of intracompany loans. As the latter may not be driven by the same factors as equity flows, the real structure of FDI flows should be taken into consideration while evaluating the investment potential of companies. The paper examines selected issues concerning international expansion of Polish companies in the form of foreign direct investment. It provides theoretical background of the problem, explores the reasons for expansion and presents the structure of foreign direct investment by Polish industrial companies in the period 2003-2012 with regard to the equity and debt components of the flows. The study is based on the data provided by the National Bank of Poland (NBP).
Management – from Epistemology by Methodology to Social Practice of Academia Cognitive Challenges in Management Science 2
Authors: Sułkowski Łukasz 
Published: May 2015

AbstractThe aim of the article is to present cognitive challenges in the area of management. Researchers and reflective managers still work on the identity of management belonging to the social sciences. The paper depicts the connections between cognitive problems (from the epistemological point of view), management methodology and social practice. Management sciences are parts of historical discourse and because of that epistemological and methodological levels have an impact on social practice. The main concern of this paper is the role of the management scientist, consultant and teacher. The analysis suggests that academic teacher and researcher are social roles with a character that can be called universal. Practitioner is associated rather with pragmatic aspect of management science. Practitioners are often regarded as managers, but their roles in the organisation might as well be non-managerial.

Published: May 2015

Abstract
Committee of Electronics and Telecommunications of the Polish Academy of Sciences (KEiT PAN) has been acting on behalf of scientific community in Poland since 1960. The article presents structure, statutory tasks, and Committee activities on behalf of the integration and development of electronics and telecommunications sciences and technology in Poland. The Committee of Electronics and Telecommunications of PAS is all the time an active participant of research life in the country. However, this participation is different than it used to be, and all the time is subject to intense changes. The authors present critically the current status of the Committee, but also undertake an effort to newly define the role, activity and potential of KEiT PAN, in completely new conditions of doing research in Poland, Europe and worldwide, than it was at that time, when the PAS Committees were originally defined. The conclusions, upon possible acceptance by the national research and technical communities of electronics and telecommunications, may possibly serve to change and/or optimise the work of the Committee in the near future

New Structure of Test Pattern Generator Stimulating Crosstalks in Bus-type Connections
Authors: Garbolino Tomasz 
Published: May 2015

Abstract
The paper discloses the idea of a new structure for a Test Pattern Generator (TPG) for detection of crosstalk faults that may happen to bus-type interconnections between built-in blocks within a System-on-Chip structure. The new idea is an improvement of the TPG design proposed by the author in one of the previous studies. The TPG circuit is meant to generate test sequences that guarantee detection of all crosstalk faults with the capacitive nature that may occur between individual lines within an interconnecting bus. The study comprises a synthesizable and parameterized model developed for the presented TPG in the VLSI Hardware Description Language (VHDL) with further investigation of properties and features of the offered module. The significant advantages of the proposed TPG structure include less area occupied on a chip and higher operation frequency as compared to other solutions. In addition, the design demonstrates good scalability in terms of both the hardware overhead and the length of the generated test sequence
Identification of Circuit Parameters for the Specified or Measured Performances
Authors: Rutkowski Jerzy 
Published: May 2015

Abstract
Extension of the method of analog circuit parameter identification for the specified design performances, originally presented by the same author in 1982, is described. These parameters are designated by means of PSpice simulation of the adjoint circuit to the original one. In this adjoint circuit, elements of the original circuit, described by the sized parameters, are replaced by controlled sources. Each such source is controlled by the differential voltage or current, difference between the calculated voltage or current and the specified one, with infinitely large gain. The method is applicable to both linear and nonlinear DC circuits and AC circuits and can be used in many fields of analog circuit design, such as: finding of acceptability region, analog fault diagnosis, postproduction identification and tuning. In the later cases, design performances are replaced by measurements of Circuit Under Test (CUT). Simplicity, extremely low computational complexity and high accuracy are the main benefits of the proposed, basic Circuit Theory based, approach - the solution is found after a single PSpice simulation. For better understanding of the presented methodology, five practical examples are discussed

This information is very usable during design and improvement of a special setup for chip functional tests. Improvement of the setup is a digitally assisted analog technique. It is an original idea of oscillators tuning procedure used during chip prototype testing. Such setup, oscillators tuning procedure and segmentation of sample binary images are presented
Long-term Survival of Patients with Breast Cancer and Brain Metastases: ‘The experience of the 2nd Oncology Department of Metropolitan Hospital and a brief review of the literature’
Authors: E Aravantinou-Fatorou , D Skarlos , G Klouvas , E Galani , C. Christodoulou 
Published: May 2015

Abstract
Background: Novel therapeutic approaches and new compounds during the last decade have prolonged survival of breast cancer patients with metastatic disease, resulting in higher incidence of central nervous system (CNS) metastases. Many of these patients live longer than expected.
Patients and methods: We reviewed breast cancer patients with brain metastases from our department, living longer than 1 year. Our purposes were to present patient and treatment characteristics and correlate them with disease outcome. Moreover, we aimed at reviewing the current literature.
Results: We detected 20 women with brain metastases from breast cancer, living longer than 1 year. The mean age was 41 years (range 22-61 years). One (5%) woman had luminal A breast cancer type, four (20%) patients had luminal B and HER2 negative, nine (45%) patients luminal B and HER2 positive, four (20%) patients HER2 enriched and two (10%) patients had triple-negative breast cancer. Most of them (70%) had infiltrating ductal histological type and grade 3. Moreover, the majority had known metastatic disease when brain metastases appeared. The most common sites of disease were lung, liver and bone. Median time from breast cancer diagnosis until the presence of CNS metastases was 44 months (range 6-204 months). The progression free survival (PFS) of the most chemotherapeutic schedules was according to the literature. However, PFS of some compounds exceeded all expectations. Median time of survival was 25 months (range 13-116 months). Ten patients are still alive, having achieved a median survival rate of 35 months (range 17-78 months).
Conclusion: The combination of surgery, radiotherapy, chemotherapy and anti HER2 treatments is at present the best way to extend the OS and improve the quality of life of breast cancer patients with brain metastases. Prognostic markers for assessing brain metastases are required. Application of prophylactic treatment for these patients is under consideration.
