A New Adaptive Mother Wavelet for Electromagnetic Transient Analysis
Authors: Guillén Daniel , Idárraga-Ospina Gina , Cortes Camilo 
Published: March 2016

Abstract
Wavelet Transform (WT) is a powerful technique of signal processing, its applications in power systems have been increasing to evaluate power system conditions, such as faults, switching transients, power quality issues, among others. Electromagnetic transients in power systems are due to changes in the network configuration, producing non-periodic signals, which have to be identified to avoid power outages in normal operation or transient conditions. In this paper a methodology to develop a new adaptive mother wavelet for electromagnetic transient analysis is proposed. Classification is carried out with an innovative technique based on adaptive wavelets, where filter bank coefficients will be adapted until a discriminant criterion is optimized. Then, its corresponding filter coefficients will be used to get the new mother wavelet, named wavelet ET, which allowed to identify and to distinguish the high frequency information produced by different electromagnetic transients.

Authors: Repka Marek 
Published: March 2016

Abstract
Modular reduction in extended finite fields and polynomial rings is presented, which once implemented works for any random reduction polynomial without changes of the hardware. It is possible to reduce polynomials of whatever degree. Based on the principal defined, two example RTL architectures are designed, and some useful features are noted furthermore. The first architecture is sequential and reduce whatever degree polynomials, taking 2 cycles per term. The second one is Parallel and designed for reduction of polynomials of 2(t −1) degree at most, taking 1 cycle for the whole reduction.

Critical Theory and Processual Social Ontology
Authors: Renault Emmanuel 
Published: March 2016

AbstractThe purpose of this article is to bridge the gap between critical theory as understood in the Frankfurt school tradition on the one hand, and social ontology understood as a reflection on the ontological presuppositions of social sciences and social theories on the other. What is at stake is the type of social ontology that critical theory needs if it wants to tackle its main social ontological issue: that of social transformation. This paper’s claim is that what is required is neither a substantial social ontology, nor a relational social ontology, but a processual one. The first part of this article elaborates the distinction between substantial, relational and processual social ontologies. The second part analyzes the various ways in which this distinction can be used in social ontological discussions. Finally, the third part focuses on the various possible social ontological approaches to the issue of social transformation.
Tension in the Natural History of Human Thinking
Authors: Moll Henrike 
Published: March 2016

AbstractMichael Tomasello has greatly expanded our knowledge of human cognition and how it differs from that of other animals. In this commentary to his recent book A Natural History of Human Thinking, I first critique some of the presuppositions and arguments of his evolutionary story about how homo sapiens’ cognition emerged. For example, I question the strategy of relying on the modern chimpanzee as a model for our last shared ancestor, and I doubt the idea that what changed first over evolutionary time was hominin behavior, which then in turn brought about changes in cognition. In the second half of the commentary I aim to show that the author oscillates between an additive and a transformative account of human shared intentionality. I argue that shared intentionality shapes cognition in its entirety and therefore precludes the possibility that humans have the same, individual intentionality (as shown in, e.g. their instrumental reasoning) as other apes.

Authors: Jeníček V. , Diblíková L. , Bláhová M. 
Published: March 2016

Abstract
The paper deals with electrochemical deposition of coatings of highly entropic alloys. These relatively new materials have been recently intensively studied. The paper describes the first results of electrochemical coating with highly entropic alloys by deposition from non-aqueous solutions. An electrochemical device was designed and coatings were deposited. The coatings were characterised with electronic microscopy scanning, atomic absorption spectrometry and X-ray diffraction methods and the combination of methods of thermic analysis of differential scanning calorimetry and thermogravimetry.
The influence of total reinforcement anchorage length on misinterpretation of the impact of hot-dip galvanised steel corrosion on its bond strength with concrete
Authors: Pokorný P. , Čech J. , Tej P. , Vokáč M. 
Published: March 2016

Abstract
To begin with, the intorduction of this paper summarises literature sources that wrongly interpret results of the bond strength between hot-dip galvanised reinforcements and concrete. The influence of the total reinforcement anchorage length on the bond strength results assessment was studied in detail. The numeric analysis of beam models with various testing anchorage lengths (the analysis input data comprised the results of previous bond strength tests carried out in a laboratory) unambiguously confirmed that when the bond strength between concrete and hot-dip galvanised reinforcement with a sufficient test anchorage length is tested in a beam test, the negative impact of the coating corrosion on bond strength with concrete may be biased. It is more objective to test bond strength with concrete in a pull-out test where a very short test reinforcement anchorage length is set out as a standard.
Synthesis of Graphenic Carbon Materials on Nickel Particles with Controlled Quantity of Carbon
Authors: Grehov V. , Kalnacs J. , Mishnev A. , Kundzins K. 
Published: March 2016

Abstract
A cheap, comparatively simple and effective method is proposed for the large quantity production of the sheets of graphenic carbon materials (GCM) by annealing the mixture of nickel powder with a suitable carbon amount at the temperatures close to 1000 ºC. The number of graphene layers in the sheets of GCM may be varied by altering the amount of carbon in the mixture and parameters of annealing and drying of the obtained products. Samples of GCM were prepared in the form of heat-dried GCM paper and in the form of graphene sponge with freeze-drying. The appearance of GCM on the surface of Ni particles was identified using a scanning electron microscope (SEM) at a low accelerating voltage of 5 kV. The thickness and properties of the layers were investigated by electron microscopy and X-ray diffraction. The fabrication processes were carried out at the concentrations of added carbon from 0 to 1 at%. The results obtained are fully consistent with the well-known solid phase reactions of carbon dissolution in Ni at 1000 °C and graphene or graphite precipitation on the surface with cooling down to the room temperatures.

Authors: Lungevics J. , Leitans A. , Rudzitis J. , Bulahs N. , Nazarovs P. , Kovalenko V. 
Published: March 2016

Abstract
Carbon-copper composite coatings reinforced with titanium were deposited using high power magnetron sputtering technique. Tribological and metrological tests were performed using Taylor Hobson Talysurf Intra 50 measuring equipment and CSM Instruments ball-on-disk type tribometer. Friction coefficient and wear rate were determined at 2N, 4N, 6N loads. It was revealed that friction coefficient decreased at a higher Ti concentration, which was particularly expressed at bigger applied loads. However, wear volume values tended to increase in the beginning, till Ti concentration reached about 11 %, but then decreased, thus providing better nanocoating wear resistance.

Published: March 2016

Abstract
The aim of this inquiry is to investigate the relationships among the antecedents of knowledge sharing effectiveness under the position of non-academic staff of higher learning institutions through an empirical test of a conceptual model consisting of trust, extrinsic and intrinsic motivation, leadership style, workplace spirituality and online social network. This study used the respondents from the non-academic staff of higher learning institutions in Malaysia (n = 200), utilizing a self-administered survey questionnaire. The structural equation modeling approach was used to test the proposed hypotheses. The outcomes indicate that all the antecedents play a substantial function in knowledge sharing effectiveness. In addition, perceived risk plays a mediating role between trust and knowledge sharing effectiveness. On the other hand, this research also proved the communication skill also plays a mediating role between leadership style and knowledge sharing effectiveness. This study contributes to pioneering empirical findings on knowledge sharing literature under the scope of the non-academic staff perspective.
Using CSR to mitigate information asymmetry in the banking sector
Authors: Semenescu Andreea , Curmei Cătălin Valeriu 
Published: March 2016

Abstract
The paper examines the power of corporate social responsibility to reduce information asymmetry and to act as a marketing instrument in the banking sector. Trust is the most important asset of a bank. Therefore, banks are motivated to use the most effective instruments to diminish information asymmetry with their stakeholders. The fact that cash disbursements in CSR actions are not directed towards shareholders makes them more valuable signals to other stakeholders regarding the financial soundness of the bank. The empirical study conducted based on limited dependent variable models supports the effectiveness of the CSR as marketing instrument in banking. It reveals the circumstances associated to a higher probability of an active CSR policy conducted by a banking institution. The results support the hypothesis that in the banking sector CSR is perceived as an instrument which helps stakeholders reduce information asymmetry. As marketing instrument, CSR contributes to increasing the tangibility of the banking products, decreasing their perceived variability and thus making them more attractive for the clients and allowing for differentiation between competitors.

Published: March 2016

Abstract
The current study revolves around research in sport consumption motivations exploring Nationality and Gender difference across fan motivations to watch sports in a way similar to Kwon and Trail (2001) in Indian context, a subject neglected until now. Data was collected from 260 respondents from India’s largest Private University. Findings reveal Group Affiliation as the most important motivation followed by Eustress (entertainment), Aesthetics, and Self-Esteem. Betting on sports was found as the least preferred motivation. Findings revealed Nationality having a significant impact on Group Affiliation and Aesthetics while Gender has a significant impact on Group Affiliation, Eustress as well as on level of identification with sport. These findings have implications for sports marketers of different sporting events involved in marketing of sports related activities to enhance their marketing practices. The results of the current study are of interest for physical education departments of large private Universities which can use them to promote their sports events at a large scale. The last section of the study discusses the results in detail followed by directions for future research.

Spread and Liquidity Issues: A markets comparison
Authors: Strašek Sebastjan , Bricelj Bor 
Published: March 2016

Abstract
The financial crises are closely connected with spread changes and liquidity issues. After defining and addressing spread considerations, we research in this paper the topic of liquidity issues in times of economic crisis. We analyse the liquidity effects as recorded on spreads of securities from different markets. We stipulate that higher international risk aversion in times of financial crises coincides with widening security spreads. The paper then introduces liquidity as a risk factor into the standard value-at-risk framework, using GARCH methodology. The comparison of results of these models suggests that the size of the tested markets does not have a strong effect on the models. Thus, we find that spread analysis is an appropriate tool for analysing liquidity issues during a financial crisis.
Capabilities of Statistical Residual-Based Control Charts in Short- and Long-Term Stock Trading
Authors: Žmuk Berislav 
Published: March 2016

Abstract
The aim of this paper is to introduce and develop additional statistical tools to support the decision-making process in stock trading. The prices of CROBEX10 index stocks on the Zagreb Stock Exchange were used in the paper. The conducted trading simulations, based on the residual-based control charts, led to an investor’s profit in 67.92% cases. In the short run, the residual-based cumulative sum (CUSUM) control chart led to the highest portfolio profits. In the long run, when average stock prices were used and 2-sigma control limits set, the residual-based exponential weighted moving average control chart had the highest portfolio profit. In all other cases in the long run, the CUSUM control chart appeared to be the best choice. The acknowledgment that the SPC methods can be successfully used in stock trading will, hopefully, increase their use in this field.
The Examination of Factors Relating to the Leadership Style of Nursing Leaders in Hospitals
Authors: Lorber Mateja , Treven Sonja , Mumel Damijan 
Published: March 2016

Abstract
Theories often describe leadership with different classifications, based on personality and behaviour, and have been used to establish the traits and behaviours that determine an effective leadership style. We used the quantitative methodology to investigate the determinants of the leadership style among nursing leaders in Slovene hospitals. Based on the results, we determined that demographic characteristics such as gender, age, length of employment, and level of education do not affect the choice of the leadership style. Internal organizational characteristics such as job position, emotional intelligence, communication, personal characteristics, and the decision-making process are positively associated with the leadership style. Personal characteristics are considered important when it comes to using specific leadership styles, regardless of the choice of the leadership style, which also depends on the situation and external influences.
Identification of Czech Metropolitan Regions: How to improve targeting of innovation policy
Authors: Klímová Viktorie , Žítek Vladimír 
Published: March 2016

Abstract
Concepts of national and regional innovation systems can serve as an analytical framework forming the empirical base for innovation policy creation. It is possible to distinguish various types of these systems. One of these typologies is based on the assessment of innovation deficiencies. There are three types of regions: metropolitan, peripheral, and old industrial. Metropolitan regions can be characterized by a high level of research, innovation, and patent activity. The aims of this paper are to find relevant indicators that can be used as the basis for defining metropolitan regional innovation systems and using them for the identification of Czech metropolitan regions. The results of the point method combined with the cluster analysis showed that the capital city, Prague, as well as the South Moravian, Pardubice, Central Bohemian, Pilsen, and Liberec Regions can be defined as metropolitan regions.
Compressed sensing in MRI – mathematical preliminaries and basic examples
Authors: Błaszczyk Łukasz 
Published: March 2016

Abstract
In magnetic resonance imaging (MRI), k-space sampling, due to physical restrictions, is very time-consuming. It cannot be much improved using classical Nyquist-based sampling theory. Recent developments utilize the fact that MR images are sparse in some representations (i.e. wavelet coefficients). This new theory, created by Candès and Romberg, called compressed sensing (CS), shows that images with sparse representations can be recovered from randomly undersampled k-space data, by using nonlinear reconstruction algorithms (i.e. l
1-norm minimization). Throughout this paper, mathematical preliminaries of CS are outlined, in the form introduced by Candès. We describe the main conditions for measurement matrices and recovery algorithms and present a basic example, showing that while the method really works (reducing the time of MR examination), there are some major problems that need to be taken into consideration.
The threshold contrast thickness evaluated with different CDMAM phantoms and software
Authors: Fabiszewska Ewa , Grabska Iwona , Pasicz Katarzyna 
Published: March 2016

Abstract
The image quality in digital mammography is described by specifying the thickness and diameter of disks with threshold visibility. The European Commission recommends the CDMAM phantom as a tool to evaluate threshold contrast visibility in digital mammography [1, 2]. Inaccuracy of the manufacturing process of CDMAM 3.4 phantoms (Artinis Medical System BV), as well as differences between software used to analyze the images, may lead to discrepancies in the evaluation of threshold contrast visibility. The authors of this work used three CDMAM 3.4 phantoms with serial numbers 1669, 1840, and 1841 and two mammography systems of the same manufacturer with an identical types of detectors. The images were analyzed with EUREF software (version 1.5.5 with CDCOM 1.6. exe file) and Artinis software (version 1.2 with CDCOM 1.6. exe file). The differences between the observed thicknesses of the threshold contrast structures, which were caused by differences between the CDMAM 3.4 phantoms, were not reproduced in the same way on two mammography units of the same type. The thickness reported by the Artinis software (version 1.2 with CDCOM 1.6. exe file) was generally greater than the one determined by the EUREF software (version 1.5.5 with CDCOM 1.6. exe file), but the ratio of the results depended on the phantom and diameter of the structure. It was not possible to establish correction factors, which would allow correction of the differences between the results obtained for different CDMAM 3.4 phantoms, or to correct the differences between software. Great care must be taken when results of the tests performed with different CDMAM 3.4 phantoms and with different software application are interpreted.
