Clinical Research of Streptococcal Uveitis (Clinical Cases)
Authors: Farah Constantin 
Published: September 2014

Abstract
Allergic uveitis caused by streptococci are recognized as flowing from a pesthole, the most frequent of them being considered the erythematous and the pultaceous angina. The characteristic of these angina is that they may go unnoticed, the frequency of asymptomatic forms being five times higher than those of symptomatic forms. Since the onset of angina until the early signs of ocular manifestations there is an open interval where there have been no clinical manifestations for approximately two weeks.
In the cases presented further on, the nature of streptococcal uveitis represents all immunoallergic phenomena induced by the streptococcus at the uveal level. A significant proportion of the patients presenting endogenous uveitis, despite of the classical performed treatment (non-steroidal, steroidal and immunosuppressants anti-inflammatory drugs) attain to relapsing forms (30-50%) with powerful complications that respond to late and/or inefficient treatment, managing to burn down the inflammatory phenomena, sacrificing the ocular function. The life of these patients turns out to be full of suffering, prolonged hospitalization, and some of them will count themselves among those with a visual handicap.
Relations between the tracheal and pulmonary trunk bifurcations
Authors: Manolakis Al. , Ionescu C. , Cambrea M. , Bordei P. , Iliescu D. 
Published: September 2014

Abstract
The bifurcation of the pulmonary trunk and trachea were followed on 52 cases being appreciated on the dissection and corrosion pieces and CT examinations, the arterial bifurcation being made under an very variable angle, its value ranging from 30-1080. In 82% of cases the tracheal bifurcation was done under an acute angle, with lower value than the arterial bifurcation angle. In 41 cases (78.85% of cases) the pulmonary trunk bifurcation is done under the bifurcation of the trachea, at a distance of between 0,4 - 2,8 cm, and in 8 patients (15.38% of the cases) the two bifurcations was located at the same level. Only in 3 cases (5.77% of cases), all on CT angiography, we encountered the pulmonary trunk bifurcation above tracheal bifurcation, with 0.3-0.8 cm, bifurcation of the pulmonary trunk being left lying of the tracheal bifurcation. In these cases, the bifurcation angle of the pulmonary trunk is always greater than the angle of the trachea bifurcation. On the dissected and the corrosion pieces is found that when the bifurcation is situated at different levels, the tracheal one being located cranial, the most commonly between them form a rectangular area: rhombus, more frequently, and rectangular or trapezium and rarely a pentagon or triangle. Any geometric shape to be formed between the two junctions, it is often asymmetric.
An analytical technique for solving general linear integral equations of the second kind and its application in analysis of flash lamp control circuit
Authors: Hetmaniok E. , Słota D. , Trawiński T. , Wituła R. 
Published: September 2014

Abstract
In this paper an application of the homotopy perturbation method for solving the general linear integral equations of the second kind is discussed. It is shown that under proper assumptions the considered equation possesses a unique solution and the series obtained in the homotopy perturbation method is convergent. The error of approximate solution, received by taking only the partial sum of the series, is also estimated. Moreover, there is presented an example of applying the method for approximate solution of an equation which has a practical application for charge calculation in supply circuit of the flash lamps used in cameras.
P1-TS fuzzy scheduling control system design using local pole placement and interval analysis
Authors: Smoczek J. 
Published: September 2014

Abstract
The linear parameter-varying (LPV) discrete-time model based design of a fuzzy scheduling control scheme is developed through incorporating the advantages of P1-TS theory, and applying the local pole placement method and interval analysis of closed-loop system polynomial coefficients. The synthesis of fuzzy scheduling control scheme is proposed in the form of iterative procedure, which enables to find the appropriate number of intervals of a fuzzy interpolator ensuring that a family of local linear controllers places closed-loop polynomial coefficients within a desired range. The computational complexity of multidimensional fuzzy scheduling control scheme synthesis is reduced using a fundamental matrix method and recursive procedure for fuzzy rule-based interpretation. The usability of the proposed method is illustrated by an implementation example and experimental results obtained on a laboratory scaled overhead crane
Modelling of electric current flow in 1D Pd-C nanostructure: comparison with experiment
Authors: Bielski W. , Kowalczyk P. , Czerwosz E. , Idzik A. , Rymarczyk J. 
Published: September 2014

Abstract
In this paper we propose a model of electric current flow through one-dimensional palladium-carbon nanostructure (nanowire) and compare the results of numerical computations with the experimental data. We focus on two aspects: 1) calculation of the current flow through the nanowire model, 2) determination of the macroscopic parameters in the nanocomposite in our model. Because of a complex micro-geometry of a nanowire, we apply the homogenization method to perform the numerical computations.

Published: September 2014

Abstract
The paper presents method for thermal generation reduction in low level light applications, especially where measured phenomena have random character. The algorithm was developed basing on cosmic ray measurements. The main parts of the system are: Silicon Photomultipliers (SiPM), front-end ASIC for amplifying and shaping signals. SiPM is a very sensitive device which can detect single photons. Comparing to a standard photomultiplier SiPM has a compact size, low operating voltage and it is immune to an electromagnetic field. Thermally generated signals are disadvantage of SiPM. This paper presents the measurement method to reduce influence of thermal generation.
Optimizing the minimum cost flow algorithm for the phase unwrapping process in SAR radar
Authors: Dudczyk J. , Kawalec A. 
Published: September 2014

Abstract
The last three decades have been abundant in various solutions to the problem of Phase Unwrapping in a SAR radar. Basically, all the existing techniques of Phase Unwrapping are based on the assumption that it is possible to determine discrete ”derivatives” of the unwrapped phase. In this case a discrete derivative of the unwrapped phase means a phase difference (phase gradient) between the adjacent pixels if the absolute value of this difference is less than π. The unwrapped phase can be reconstructed from these discrete derivatives by adding a constant multiple of 2π. These methods differ in that the above hypothesis may be false in some image points. Therefore, discrete derivatives determining the unwrapped phase will be discontinuous, which means they will not form an irrotational vector field. Methods utilising branch-cuts unwrap the phase by summing up specific discrete partial derivatives of the unwrapped phase along a path. Such an approach enables internally cohesive results to be obtained. Possible summing paths are limited by branch-cuts, which must not be intersected. These branch-cuts connect local discontinuities of discrete partial derivatives. The authors of this paper performed parametrization of the Minimum Cost Flow algorithm by changing the parameter determining the size of a tile, into which the input image is divided, and changing the extent of overlapping of two adjacent tiles. It was the basis for determining the optimum (in terms of minimum Phase Unwrapping time) performance of the Minimum Cost Flow algorithm in the aspect of those parameters.

Authors: Iwański M. , Mazurek G. 
Published: September 2014

Abstract
The reduction in asphalt mixture production and placement temperatures can be achieved by modifying bitumen 35/50 with the Fischer-Tropsch synthetic wax. To identify the role this modifier plays in the bitumen 35/50, a series of tests has been performed. The experiment was carried out for wax doses from 1.5% to 4.0%. Analysis of the modified binder properties such as ductility at 5, 15 and 25◦C, complex modulus G* with the parameter G*/sinx and LSV, susceptibility according to MSCR procedure, morphology and group type analysis helped describe the structuring function of the F-T wax in the binder. The optimum F-T wax content of 2.5% has been identified to provide the desired parameters required for modified binders.
Modelling and optimal control system design for quadrotor platform – an extended approach
Authors: Zawiski R. , Błachuta M. 
Published: September 2014

Abstract
This article presents the development of a mathematical model of a quadrotor platform and the design of a dedicated control system based on an optimal approach. It describes consecutive steps in development of equations forming the model and including all its physical aspects without commonly used simplifications. Aerodynamic phenomena, such as Vortex Ring State or blade flapping are accounted for during the modelling process. The influence of rotors’ gyroscopic effect is exposed. The structure of a control system is described with an application of the optimal LQ regulator and an intuitive way of creating various flight trajectories. Simulation tests of the control system performance are conducted. Comparisons with models available in the literature are made. Based on above, conclusions are drawn about the level of insight necessary in creation of control-oriented and useable model of a quadrotor platform. New possibilities of designing and verifying models of quadrotor platforms are also discussed.
Exit selection process during crowd evacuation, modelled on the cockroach emergent behaviour
Authors: Zajdel M. , Filipowicz B. 
Published: September 2014

Abstract
Groups of living creatures are often faced with searching for resources and choosing between one or more alternatives of resource site. Such a process is connected either with calm food acquirement or looking for a safe place to hide from danger. The question is, what kind of criteria are taken into consideration and what induces the collective decision, when all individuals in a swarm are equal. This paper identifies a simple mechanism of shelter selection by cockroach herd, whereby an emergent decision is made with limited information and without centralization of information processing or comparison of available solutions. The mechanism leads to the optimal benefit for both a group and an individual. The proposed model activates swarm self-organization and is independent of species, therefore, a possible application to human crowd control has been studied.

Published: September 2014

Abstract
This paper presents an analysis of issues related to the fixed-point implementation of a speech signal applied to biometric purposes. For preparing the system for automatic speaker identification and for experimental tests we have used the Matlab computing environment and the development software for Texas Instruments digital signal processors, namely the Code Composer Studio (CCS). The tested speech signals have been processed with the TMS320C5515 processor. The paper examines limitations associated with operation of the realized embedded system, demonstrates advantages and disadvantages of the technique of automatic software conversion from Matlab to the CCS and shows the impact of the fixed-point representation on the speech identification effectiveness.
Multicriteria Evaluation of Managerial Competences: An Application of the Dominance Principle and the Rough Set Theory
Authors: Gaia Do Couto Ayrton Benedito , Autran Monteiro Gomes Luiz Flavio 
Published: September 2014

Abstract
This study demonstrates an analysis of executives based on their management competences. The aim of the study is to identify those executives that show a greater strategic alignment with the guidelines set by an organization. The analysis is performed using self-evaluation and corporate evaluation by considering each management competence as a criterion. It makes use of the Dominance principle (i.e., the Dominance based Rough Set Approach, denoted here as DRSA). The use of DRSA permits the inference of decision rules and identifies the revisions that violate that principle. The main advantage for an organization from using this procedure (i.e., DRSA and RST) is offering the organizational decision makers a comprehensive analysis of their executives. As a major result, training programs aligned to the expectations and needs of the organization can be developed and implemented
Holistic Entropy Reduction for Collaborative Filtering
Authors: Szwabe Andrzej , Misiorek Pawel , Janasiewicz Tadeusz , Walkowiak Przemyslaw 
Published: September 2014

Abstract
We propose a collaborative filtering (CF) method that uses behavioral data provided as propositions having the RDF-compliant form of (user X, likes, item Y ) triples. The method involves the application of a novel self-configuration technique for the generation of vector-space representations optimized from the information-theoretic perspective. The method, referred to as Holistic Probabilistic Modus Ponendo Ponens (HPMPP), enables reasoning about the likelihood of unknown facts. The proposed vector-space graph representation model is based on the probabilistic apparatus of quantum Information Retrieval and on the compatibility of all operators representing subjects, predicates, objects and facts. The dual graph-vector representation of the available propositional data enables the entropy-reducing transformation and supports the compositionality of mutually compatible representations. As shown in the experiments presented in the paper, the compositionality of the vector-space representations allows an HPMPP-based recommendation system to identify which of the unknown facts having the triple form (user X, likes, item Y ) are the most likely to be true in a way that is both effective and, in contrast to methods proposed so far, fully automatic.
Variables and Values in Children’s Early Word-Combinations
Authors: Ninio Anat 
Published: September 2014

Abstract
A model of syntactic development proposes that children’s very first word-combinations are already generated via productive rules that express in syntactic form the relation between a predicate word and its semantic argument. An alternative hypothesis is that they learn frozen chunks. In Study 1 we analyzed a large sample of young children’s early two-word sentences comprising of verbs with direct objects. A majority of objects were generated by pronouns but a third of children’s sentences used bare common nouns as objects. We checked parents’ twoword long sentences of verbs with objects and found almost no bare common nouns. Children cannot have copied sentences with bare noun objects from parents’ two-word long sentences as frozen chunks. In Study 2 we raised the possibility that children’s early sentences with bare nouns are rote-learned ‘telegraphic speech’, acquired as unanalyzed frozen chunks from longer input sentences due to perceptual problem to hear the unstressed determiners. To test this explanation, we tested the children’s speech corpus for evidence that they avoid determiners in their word-combinations. The results showed that they do not; in fact they generate very many determiner-common noun combinations as two-word utterances. The findings suggest that children produce their early word-combinations of the core-grammar type by a productive rule that maps the predicate-argument relations of verbs and their semantic arguments to headdependent syntax, and not as frozen word-combinations. Children mostly learn to use indexical expressions such as pronouns to express the variable semantic arguments of verbs as context dependent; they also employ bare common nouns to express specific values of the arguments. The earliest word-combinations demonstrate that children understand that syntax is built on the predicate-argument relations of words and use this insight to produce their early sentences.
Two routes to closure: Time pressure and goal activation effects on executive control
Authors: Kossowska Małgorzata , Bukowski Marcin , Czarnek Gabriela 
Published: September 2014

Abstract
In the present study the impact of need for cognitive closure (NFC) manipulations via time pressure and explicit closure goal activation on executive control was investigated. Although there is some evidence that NFC, measured as an individual variable, is related to better performing in attentional tasks involving executive control, these results have never been validated across different manipulations of NFC. Thus, in the present study we induced NFC via internal and external time pressure and tested the impact of these manipulations on the performance in tasks that measure executive control, i.e., the Stroop and switching tasks. The results revealed that induced high (vs. low) NFC, indeed boosted performance in executive control tasks. Moreover, there was no difference in the effect of both NFC manipulations on task performance. The implications regarding the role of executive control and specific NFC manipulations in social cognition are discussed.
The effect of metacognitive self on confirmation bias revealed in relation to community and competence
Authors: Brycz Hanna , Wyszomirska-Góra Magdalena , Bar-Tal Yoram , Wiśniewski Piotr 
Published: September 2014

Abstract
The main goal of our study was to investigate the role of insight into one’s own biases (metacognitive self) in the process of hypothesis validation in accordance to the two fundamental social perception domains (community and competence) on the example of confirmation bias. The study was conducted on a group of 593 participants with the use of a confirmation bias procedure, a free recall procedure and the Metacognitive Self scale. We manipulated with the domain and the value of information given to the respondents. We suspected that individuals with a high metacognitive self, in opposition to low metacognitive self ones, would not process the given information according to the two fundamental social perception domains. The results verified the existence of an interaction effect of the metacognitive self (MCS) and the domain of the information given about a perceived person on the susceptibility to follow the confirmation bias. Contrary to the low metacognitive self individuals, who show a higher tendency for the confirmation bias within the competence than the community domain, persons with a high insight into their own biases express the same level of confirmation bias in no respect to the domain of the information. The value of the information has no significant influence.
The impact of incidental fear and anger on in- and outgroup attitudes
Authors: Bukowski Marcin , Dragon Piotr , Kossowska Małgorzata 
Published: September 2014

Abstract
The aim of this research was to examine the impact of two specific negative emotions of anger and fear on intergroup attitudes. In Study 1 we measured emotions of anger and fear and in Study 2 we evoked these emotions incidentally, that is independently of any intergroup context. In both studies we measured attitudes towards the ingroup (Polish) and the outgroup (Gypsies).We expected that fear would lead to more positive ingroup attitudes and anger to more negative outgroup attitudes. The results of the correlational study (Study 1) confirmed the predictions regarding anger and decreased outgroup evaluations, and the experimental study (Study 2) revealed that fear enhanced positivity towards the ingroup, but anger increased negativity towards the outgroup. The impact of fear and anger on social attitudes in the specific context of a negatively self-stereotyped ingroup is discussed.
Formation of homosexual orientation of men in adolescence
Authors: Katra Grażyna 
Published: September 2014

Abstract
The aim of the study was to explore the experiences of homosexual men connected with the formation of their sexual orientation in adolescence. A comparative study of 27 young adult homosexual men and 28 heterosexual men of similar age used a categorised interview questionnaire consisting of two parts: the first with questions regarding sexual dreams, fantasies and erotic encounters; the second with questions on family and social circumstances.
The study yielded an abundance of interesting data on the psychological circumstances of homosexual men during the formation of sexual orientation and its awareness as well as differences and similarities in that area between homosexual and heterosexual men. For instance, it revealed experience patterns concerning the formation of sexual identity and personal attitudes toward one’s sexual orientation characteristic of homosexual persons. The study verified the main hypothesis that mental-internal experiences precede behavioural-external ones both in homosexual and heterosexual persons.
Cognitive dysfunctions associated with white matter damage due to cardiovascular burden – determinants and interpretations
Authors: Krukow Paweł 
Published: September 2014

AbstractAlthough considerable research has been devoted to cognitive functions deteriorating due to diseases of cardiovascular system, rather less attention has been paid to their theoretical background. Progressive vascular disorders as hypertension, atherosclerosis and carotid artery stenosis generate most of all pathological changes in the white matter, that cause specific cognitive disorder: disconnection syndromes, and disturbances in the dynamic aspect of information processing. These features made neuropsychological disorders secondary to cardiovascular diseases different than the effects of cerebral cortex damage, which may be interpreted modularly.
