Opis:

In the world of Western musicology music is regarded as possessing two main divisions. The first being performance features which consist of traits such as dynamics, and tempo, and a second known as structural features such as the arrangement of notes in time. The main differences between these divisions is that performance features are evolutionarily ancient, indiscrete and present in many sound expressions, whereas structural features are evolutionarily younger, discrete and music-specific. Performance features are tightly connected with motor activity and emotional processing. Despite the fact that performance features carry information about emotional states, they can also be used as tools of manipulation. It has been proposed that one biological function of these tools is to affect the minds of other animals in order to arouse the need for cooperation in them. It has also been suggested that music performance features are homologous with some prosodic features of speech which evolved as a communicative tool before language and music.

Opis:

In order to study the rotational features induced by evaporating water several laboratory experiments were conducted with airborne rotary detection discs made of absorbent cotton wool and ultralight polyurethane foam discs. Measurements indicated that water vapor develops and transits into the air an upwardly directed counterclockwise rotary motion in the Northern Hemisphere, and a clockwise motion in the Southern Hemisphere. Additionally, measurements of the thermal structure of the air/water interface indicated that evaporating water may gather rotational momentum in the warmer subsurface layer. The conducted observations suggest that the process of water evaporation may be based on the grouping of some coherently spiraling molecules in the liquid phase. The interacting molecules combine their partial rotational momentums, thus allowing the top molecule to transit via the surface tension microlayer and become airborne. At the moment of evaporation, the gathered rotational energy is taken over by the free bi-hydrogen rotor-arm of the evaporating molecule that starts to revolve. Next, the water vapor-induced rotational share of the kinetic energy is likely to be redistributed among other gaseous molecules and transferred into heat (during condensation) that further energizes the airborne convective loops. In order to confirm the rotary effects induced by water vapor, several field experiments were conducted with airborne rotary detection ribbons in the Northern Hemisphere. The observations confirmed that a more enhanced counterclockwise spiraling motion of air is found with air currents under atmospheric lows of a higher relative humidity, while weaker and clockwise directed rotary dominates under atmospheric highs.

Opis:

The study is aimed to investigate the properties of auditory-based features for audio change point detection process. In the performed analysis, two popular techniques have been used: a metric-based approach and the ∆BIC scheme. The efficiency of the change point detection process depends on the type and size of the feature space. Therefore, we have compared two auditory-based feature sets (MFCC and GTEAD) in both change point detection schemes. We have proposed a new technique based on multiscale analysis to determine the content change in the audio data. The comparison of the two typical change point detection techniques with two different feature spaces has been performed on the set of acoustical scenes with single change point. As the results show, the accuracy of the detected positions depends on the feature type, feature space dimensionality, detection technique and the type of audio data. In case of the ∆BIC approach, the better accuracy has been obtained for MFCC feature space in the most cases. However, the change point detection with this feature results in a lower detection ratio in comparison to the GTEAD feature. Using the same criteria as for ∆BIC, the proposed multiscale metric-based technique has been executed. In such case, the use of the GTEAD feature space has led to better accuracy. We have shown that the proposed multiscale change point detection scheme is competitive to the ∆BIC scheme with the MFCC feature space.

In the article it is shown that folklore and ethnographic records are an important source of historical research into Podillya dialects. S. Rudanskiy, K. Sheykovskiy, A. Kopitskiy, A. Dyminskiy, Marko Vovchok and O. Markovych played an important role in researching oral folk art. The author of the research analysed the texts of Ukrainian fairytales, which were recorded in the Podillya region in the middle of the 19th century by A. Dyminskiy and S. Rudanskiy, and composed by M. Levchenko. The texts of these fairytales fix a great number of Podillian phonetical features, which still exist even now and which demonstrate the remoteness and vitality of these dialects. It has been proved that only authentic texts can serve as a valuable and reliable source for linguistic study of the dynamic Podillyan people’s dialect.

Japanese English (JE) refers to the English spoken by Japanese citizens. This paper characterizes JE by examining its lexicogrammatical features produced by five speakers participating in experimental recordings. Drawing on the initiatives taken by Cogo and Dewey’s seminal work (2012), this study presents nine lexicogrammatical features which are taken to be typical of JE. It is shown that one decisive factor in creating a new variant is the formation of an alternative form to its native counterpart and this mechanism is sourced from the speaker’s multiple knowledge about two languages.

Opis:

In this paper a novel definition and understanding of colour correlogram has been proposed. The proposed colour correlogram generalizes the spatial graylevel dependency matrix (SGLDM) to the case of colour textures. This generalization is based on perceptual colour difference measure expressed in the language of the CIELab colour space components. Application of the colour difference instead of arbitrary colour indices or colour components themselves allows to avoid colour-shuffling palletization and introduction of multidimensional objects, respectively; the proposed perceptual colour correlogram is a single 2D matrix. At the same time, a simple relation of the proposed colour correlogram to the spatial graylevel dependency matrix for graylevel textures is retained. Based on this relation it will be shown that there exists a vector of statistical features built from the perceptual colour correlogram which can be used to describe textures in perceptual terms. These statistical features and their abovementioned perceptual interpretation generalize Haralick concepts derived for the SGLDM.

Opis:

Ustalenie strony podmiotowej danego przestępstwa, czyli stosunku wolicjonalno-intelektualnego sprawcy do zarzucanego mu czynu, jest nad wyraz istotne dla rozstrzygnięcia sprawy choćby dlatego, że wpływa na wymiar kary. O ile w przypadku osoby poczytalnej co do zasady ustalenie strony podmiotowej nie stanowi trudności, o tyle w przypadku sprawcy niepoczytalnego jego zaburzenia psychiczne utrudniają wspomniane ustalenie. Zaburzenia te powodują, że cierpiące na nie osoby niekiedy w inny sposób odczuwają wolę popełnienia czynu bądź jej brak, a także w inny sposób aniżeli osoby poczytalne przewidują lub nie przewidują możliwości popełnienia czynu zabronionego. W związku z tym kwestia ustalenia strony podmiotowej czynu zabronionego w przypadku popełnienia tego czynu przez sprawcę niepoczytalnego jest przedmiotem sporu w doktrynie. Autor swoje rozważania zacznie od omówienia, czym jest strona podmiotowa, a także czym jest niepoczytalność w rozumieniu kodeksu karnego z 1997 roku. Przedstawi także przykładowe poglądy doktryny co do omawianego problemu, niekiedy będące sobie przeciwstawne. Przytoczy również wybrane orzeczenia związane z omawianą materią. Następnie przedstawi własne stanowisko, odnosząc się przy tym do poglądów przedstawicieli doktryny.
Attributing the subjective features of the crime, in other words volitional and intellectual attuite at criminal act committed by perpetrator, is extremally important for settle the matter, if only because it have an influence at the punishment. In case of sane person in principle attributing subjective features is not difficult. But in case of insane perpetrator, perpetrator’s mental disorder impedes this attributing. This disorder cause that insane person sometimes in another way feels the desire to committing of criminal act or not. Insane persons also in another way than sane persons predicts or not possibility of committing the criminal act. Therefore issue of attributing subjective features of the criminal law in case of committing criminal act by insane perpetrator is issue in a dispute in Polish doctrine of criminal law. The author will start his consideration at elaborate what is subjective feature and insanity in sense of Criminal Code from 1997. Author will presents also examples of the Polish doctrine of criminal law views as to this problem, which are sometimes extremely different. The author also will quote some judgments as to this problem. At next the author will elaborate his opinion in the issue of attributing subjective features.

Opis:

Airborne Laser Scanning (ALS) products are now often used to study the terrain due to their numerous advantages such as relatively low cost and ease of data collection. The ISOK project (pl: Informatyczny System Osłony Kraju – national hazard protection information system) developed elevation data for about 65% of the Polish territory. Parallel to the airborne laser scanning point cloud collection, additional products, such as orthophotomaps, digital terrain models (DTM), and digital surface models (DSM) were created. This resource is not only a reference material for the project, but also a valuable source of the analysis used in various fields of economy and science. Important features of the ISOK-data are the availability and their standardized format based on uniform technical conditions. The article presents the results of an experiment in which an attempt was made to use the digital elevation model with a resolution of 1 m based on airborne laser scanning data to determine concave terrain features using GIS tools. The ISOK-DTM has a height accuracy of 0.15 m for the outdoor areas, which makes it a better representation of small terrain forms than previous products. The research area is located at an undeveloped open ground with comparatively little variation of its shape for a long period. Several methods were tested to classify the terrain shape based of topographic attributes. Those methods led to similar locations of the concave features and further on coincide with results of the pre-analysis. Also, attention was drawn to the selection of the analysis parameters and their influence on the result. The results show the usefulness of ISOK’s DTM for locating field concave terrain shapes.

Opis:

An automatic analysis of product reviews requires deep understanding of the natural language text by machine. The limitation of bag-of-words (BoW) model is that a large amount of word relation information from the original sentence is lost and the word order is ignored. Higher-order-N-grams also fail to capture the long-range dependency relations and word order information. To address these issues, syntactic features extracted from the dependency relations can be used for machine learning based document-level sentiment classification. Generalization of syntactic dependency features and negation handling is used to achieve more accurate classification. Further to reduce the huge dimensionality of the feature space, feature selection methods based on information gain (IG) and weighted frequency and odds (WFO) are used. A supervised feature weighting scheme called delta term frequency-inverse document frequency (TF-IDF) is also employed to boost the importance of discriminative features using the observed uneven distribution of features between the two classes. Experimental results show the effectiveness of generalized syntactic dependency features over standard features for sentiment classification using Boolean multinomial naive Bayes (BMNB) classifier.

Opis:

Despite the fact, that dense SLAM systems are extensively developed and are getting popular, feature based ones still have many advantages over them. One of the most important matters in sparse systems are features. The performance and robustness of a system depends strictly on the quality of constraints imposed by feature observations and reliable matching between measurements and features. To improve those two aspects, higher-level features can be used, and planes are a natural choice. We tackle the problem of plugging planes into the g2o optimization framework with two distinct plane representations: one based on a properly stated SE(3) parametrization and one based on a minimal parametrization analogous to quaternions. Proposed solutions were implemented as extensions to the g2o framework and experiments that verify them were conducted using simulation. We provide a comparison of performance under various conditions that emphasized differences.

Firstly, the origin and the background of the division of music genres were shortly presented. Then, several objective parameters of an audio signal were recalled that have an easy interpretation in the context of perceptual relevance. Within the study parameter values were extracted from music excerpts, gathered and compared to determine to what extent they are similar within the songs of the same performer or samples representing the same piece.

Opis:

Among the main factors that affect residential mobility, satisfaction of households from their living environment and dwelling is outstanding since it covers most of the related variables. The extent to which households expectations are met by their residential environment depends on the socioeconomic features matching the physical and spatial qualities of their living environment. This paper aims to contribute to theory and practice concerning residential satisfaction in housing through an assessment of the Göktürk residential neighbourhood and its housing, and its relationship to households’ residential mobility. Göktürk, which is located in the northwestern periphery of Istanbul, is a significant residential area, with the majority of its inhabitants live in houses with luxury lifestyle while other households are living in informal settlements with the lowest quality of housing and neighbourhood. In the first section of this paper, an overview of the residential texture of the Göktürk neighbourhood is discussed. Following this, the methodology and analysis of findings covering 210 households’ views living in two main segments in terms of their socio-economic characteristics are reviewed. Finally, the physical features of neighbourhood such as housing and status of its quality are discussed to explore the overall satisfaction of respondents with their current situation. The importance of this research is that, in this area, two income groups of households which are very different from each other are living side by side. The major findings reveal that most households are satisfied with the quality of neighbourhood while a significant number of high-income households are dissatisfied with the environmental quality of neighbourhood and are satisfied with their housing, whereas some middle- and upper-class households are dissatisfied with their housing. It should be noticed that low-income households continue to admit that they are satisfied with their homes, despite the fact that they are living in squatter settlements, indicating that they do not want to lose their houses even with the least level of quality.

Opis:

Agricultural production has a number of special features which essentially distinguish it from other sectors of national economy (industry, building industry, trade, etc.) The general regularities often prevail very specifically. The agricultural production is performed in open areas, exposed to the force of nature, closely connected to the land. The land has a primary role in farming, and a major part of expenditures are utilised through arable land. The natural and economic attributes of arable land and the inseparably related climate conditions substantially determine the method and success of farming. Farming specialties often require special accounting solutions which can also be found in the case of agricultural enterprises. The objective of the present paper is to examine the assessment procedures in regard to agricultural enterprises which can be applied in the case of fixed assets.

Opis:

Poland and Polish people are shown in the Aleksandr Solzhenitsyn’s writing in the context of complicated Polish-Russian relations. In Repentance and Self-limitation the author criticises Polish nation for being unable to repent and admit making mistakes in the past in a historical context. At the same time he claims that Russians have a natural ability to repentance, that is a condition of a moral renewal of a nation. Nevertheless, the overall picture of the Polish nation in Solzhenitsyn’s writing is positive. This Russian Nobel prize winner highlights Polish courage, pride and their undeterred struggle for freedom. In The Gulag Archipelago the author eternalises a Polish scientist named Jerzy Wegierski, a prisoner of a forced labour camp, who had been Solzhenitsyn’s friend till his death. It is also very important to highlight Solzhenitsyn’s respect and attitude toward the Pope John Paul II. The article is an attempt to recall and analyse Polish features in the Aleksandr Solzhenitsyn’s writing.

Opis:

This article concerns a key topic in the field of visual object recognition – the use of features. Object recognition algorithms typically rely on a fixed vector of pre-selected features extracted from 2D or 3D scenes, which are then analyzed with various classification techniques. On the other hand, the activation of particular features in biological vision systems is hierarchical and data-driven. To achieve a deeper understanding of the subject, we have introduced several mathematical tools to estimate multiple RGB-D features’ relevance for different object recognition tasks and conducted statistical experiments involving our database of high quality 3D point clouds. From the thorough analysis of the obtained results we draw conclusions that may be useful to design better, more adaptive object recognition algorithms.

Opis:

The paper describes features of landscape boundaries in the lowland landscape of Poland and verifies their cross-scale properties. The diversity of lithology, morphometry and land use was taken into account by delimitation of the boundaries. A scale of 1:50 000 was set as the basis. Three structural features (length, contrast and sinuosity) and two functional features (permeability and stability) were examined. The boundaries within the research area are typically of average length, low sinuosity, high permeability and low stability. A high correspondence between the diversity of abiotic components and land use is observed, resulting in a large number of high-contrast boundaries. However, this feature does not necessarily mean that these patterns are cross scale and can be applied at a higher level of landscape hierarchy. A geochemical/typological and regional order has been explored to describe properties of landscape boundaries for different spatial scales. Only the first of the listed orders corresponds to diversification of boundary features.

Opis:

This research aimed at testing multiple fitness hypothesis of attraction, investigating relationship between male facial characteristic and female students' reported readiness to engage in various social relations. A total of 27 male photos were evaluated on five dimensions on a seven-point Likert-type scale ranging from -3 to 3, by convenient sample of 90 female students of University of Sarajevo. The dimensions were: desirable to date – not desirable to date; desirable to marry – not desirable to marry; desirable to have sex with – not desirable to have sex with; desirable to be a friend – not desirable to be a friend; attractive - not attractive. Facial metric measurements of facial features such as distance between the eyes, smile width and height were performed using AutoCad. The results indicate that only smile width positively correlates with desirability of establishing friendship, whilst none of the other characteristics correlates with any of the other dimensions. This leads to the conclusion that motivation to establish various social relations cannot be reduced to mere physical appearance, mainly facial features, but many other variables yet to be investigated.

Uzasadniono potrzebę tworzenia kompletnego i spójnego systemu miar cech od poziomu przedsiębiorstwa do poziomu elementu obiektu systemu technicznego. Zaznaczono, że istotą takiego systemu powinna być możliwość wyznaczania wartości miar cech jednego poziomu dekompozycji na podstawie wartości miar cech sąsiedniego poziomu dekompozycji systemu.
The enterprise operating in the social market economy is characterized, the features of enterprise has been listed and life phases of technical objects been presented. The assets of the enterprise are decomposed and following concepts are specified: production system, technical object, objects of technical systems. The problem of features and features structure of the production system is touched. The operating potential influence on other features of the production system is pointed out. The relationship between the features of the production system and the features of the enterprise is pointed out. It is the concept of real value und required value of given feature introduced. It has been shown the need to equalize the values of the real and required measures of the features of production system. The algorithms to equalize the measure at the level of technical systems, technical system objects, object functional units and parts of objects are presented. Described are methods and means of equalizing the measures values of features. To each level is assigned a manner of the implementation of value feature equalization. The problem of feature identification of each level of decomposition of the production system is touched. The role of maintenance in equalizing the features measures values of the production system is indicated. The methodology to objects identity used in the maintenance is characterized. The role of asset management in equalizing of features measures values of production system is described. The need to create a complete and coherent system of features from enterprise level to the level of an object element of the technical system is justified. It was noted that the essence of such a system should be able to designate the features values of one level of decomposition on the bases of features values of the adjacent level of decomposition system.

Opis:

Based on the analysis of entries from Polański 1999, the present work – as its title indicates - explores “the location of phonological distinctive features in the structure of individual types of voice features”. The exploration of this topic will enable us to properly comprehend the notion of ‘distinctiveness’ (primarily in linguistics, but - through natural expansion - also in other domains of sciences). We will address such questions as: what it is (and what it is not), how to understand it, what kinds of distinctiveness exist, and which of its aspects we might deal with.

Opis:

Part of the Oxfordian carbonate buildups in the southern part of the Kraków Upland is developed as pseudonodular limestones, which represent segment reefs. These limestones are composed of connected, rounded-oval to subangular carbonate pseudonodules. The pseudonodules, densely packed within the limestone, fall out easily under mechanical stress. The recently observed texture of pseudonodular limestones resulted from two stages of chemical compaction. During the first stage, in the Late Jurassic, high-amplitude and low-amplitude stylolites and dissolution seams were formed. The sites particularly favourable for the development of high-amplitude stylolites were the boundaries between already lithified fragments of the laminar, rigid microbial-sponge framework. The low-amplitude stylolites formed mainly in the intercalated wackestone-packstone, which was lithified somewhat later; hence, the dissolution seams originated at the contacts between the rigid microbial-sponge framework and the wackestonepackstone. After Early Cretaceous erosion, which decreased the burial load, Late Cretaceous sedimentation enabled the renewal of pressure dissolution. Thus, some low-amplitude stylolites evolved into dissolution seams. In stylolites composed of both low- and high-amplitude segments, dissolution proceeded at the bases of interpenetrating high-amplitude stylolite columns, with the simultaneous transformation of low-amplitude stylolite segments into dissolution seams. These seams, which formed at the initial stage of chemical compaction, were subjected in turn to further pressure dissolution, giving rise to the formation of horsetail structures. The vertical stress field, which triggered the pressure dissolution processes, presumably resulted in the formation of high-angle and vertical incipient tension gashes. At the beginning of the processes, these gashes remained closed. In the Cenozoic, under the extensional regime generated by overthrusting Carpathian flysch nappes, some high-angle and vertical dissolution seams and low-amplitude stylolites opened up, forming deformed dissolution seams and deformed stylolites. Under the same conditions, the high-angle and vertical tension gashes opened up as well. Subsequently, during the exposure period, unloading fractures developed, partly as a result of the opening of some subhorizontal and horizontal dissolution seams and stylolites. The unloading fractures, along with the already existing vertical and high-angle tension gashes, formed the network changing the limestone into pseudonodules of various shapes and sizes. The open spaces between the limestone fragments became local conduits for karst waters.

Opis:

Nowadays volunteered geographic information (VGI) and collaborative mapping projects such as OpenStreetMap (OSM) have gained popularity as they not only offer free data but also allow crowdsourced contributions. Spatial data entry in this manner creates quality concerns for further use of the VGI data. In this regard, this article focuses on the assessments of geometric and semantic quality of the OSM building features (BFs) against a large-scale topographic (TOPO) data belonging to some areas of Istanbul. The comparison is carried out based on the one-to-one matched BFs according to a geometric matching ratio. In geometric terms, various parameters of position (i.e. X, Y), size (i.e. area, perimeter and granularity), shape (i.e. convexity, circularity, elongation, equivalent rectangular index, rectangularity and roughness index), and orientation (i.e. orientation angle) elements are computed and compared. In semantic terms, BF type coherences are evaluated. According to the findings of geometric quality, the average positional difference was less than three meters. In addition, the perimeter values tended to decrease while area and granularity values tended to increase in OSM data against TOPO data. Those showed that the level of the detail of the OSM BFs was lower than TOPO BFs in general. This was also confirmed by the decreasing tendency of shape complexity according to the parameters of shape element. Orientation angle differences was often low except for some special cases. It was found that the scale of the OSM dataset, even though not homogenous, approximately corresponded to the lower limit of medium scale maps (i.e. 1:10,000) or a slightly smaller scale. According to the findings of semantic quality, in case of the presence of specific type definition, the coherence was rather high between OSM and TOPO BFs while the most OSM BFs did not have a specific type attribute. This study showed that the matching process needed some improvements while the followed approach was largely successful in the evaluation of the matched buildings from geometric and semantic aspects.

Celem pracy było określenie zależności pomiędzy cechami geometrycznymi ziarna zbóż. Zakres pracy obejmował pomiar podstawowych wymiarów ziarna (szerokość, grubość i długość) oraz obliczenie jego objętości, powierzchni zewnętrznej i współczynnika sferyczności. Pomiary przeprowadzono na ziarnie 11 odmian jęczmienia (Gregor, Gil, Sigra, Bombay, Tiffany, Stratus, Rudzik, Rodos, Rodion, Rastik, Orthega) oraz 4 odmianach owsa (Szakal, Bajka, Dukat, Akt). Wykazano, że dla ziarna jęczmienia za podstawową cechę rozdzielczą należy przyjąć szerokość ziarna, natomiast dla owsa jego długość. Ponadto stwierdzono istotną (p<0,05) zależność pomiędzy podstawowymi wymiarami ziarna (współczynniki korelacji powyżej 0,95) oraz duże wyrównanie właściwości geometrycznych ziarna w obrębie każdego z badanych gatunków zbóż.
The purpose of the work was to determine the dependencies between geometric features of corn grains. The scope of work included measurement of main grain dimensions (width, thickness and length) and calculation of grain volume, external surface and sphere factor. The measurements were performed on grain of 11 varieties of barley (Gregor, Gil, Sigra, Bombay, Tiffany, Stratus, Rudzik, Rodos, Rodion, Rastik, Orthega) and 4 varieties of oat (Szakal, Bajka, Dukat, Akt). It was demonstrated that a basic distribution quality, which should be adopted for barley grain iswidth, and for oat it is length. Furthermore, the measurement showed significant (P<0,05) dependence between basic dimensions of grain (correlation coefficients higher than 0,95) and high balancing of geometric properties of grain for each tested corn types.

Opis:

In this paper it is stated, that a set of quality features of metal matrix composite castings differs from the same set for castings of classic materials, although some features are common for both of these material groups. These features (pertaining to a set of quality characteristics of composite castings) have been named as specific, they have not been determined yet and a description of material quality should be performed (according to the qualitology) on a principle of description of quality characteristics of this product. Therefore, this set of features has been determined. It was proposed to add the following characteristics to the set of specific features of composite castings quality: matrix material, reinforcement material, binding between components and porosity of the composite casting. In this set a sub-set of quality characteristics of composite castings was also determined.
Stwierdzono, że zbiór cech jakości metalowych odlewów kompozytowych różni się od zbioru cech jakości odlewów z materiałów klasycznych, choć niektóre cechy są zbieżne dla obu tych grup materiałowych. Cechy te (należące do zbioru cech jakości odlewów kompozytowych) nazwano specyficznymi, nie były one dotychczas określone, a opis jakości materiałów powinien odbywać się (w myśl kwalitologii) na zasadzie opisu cech jakości tego wyrobu. Określono zatem ten zbiór cech. Zaproponowano, aby do zbioru specyficznych cech jakości odlewów kompozytowych zaliczyć: materiał osnowy, materiał zbrojenia, połączenie pomiędzy komponentami i porowatość odlewu kompozytowego. W zbiorze tym określono również podzbiór cech jakości odlewów kompozytowych.

Opis:

The training set consists of many features that influence the classifier in different degrees. Choosing the most important features and rejecting those that do not carry relevant information is of great importance to the operating of the learned model. In the case of data streams, the importance of the features may additionally change over time. Such changes affect the performance of the classifier but can also be an important indicator of occurring concept-drift. In this work, we propose a new algorithm for data streams classification, called Random Forest with Features Importance (RFFI), which uses the measure of features importance as a drift detector. The RFFT algorithm implements solutions inspired by the Random Forest algorithm to the data stream scenarios. The proposed algorithm combines the ability of ensemble methods for handling slow changes in a data stream with a new method for detecting concept drift occurrence. The work contains an experimental analysis of the proposed algorithm, carried out on synthetic and real data.

Opis:

In this paper a new method of handwritten signatures verification has been proposed. This method, for each signature, creates complex features which are describing this signature. These features are based on dependencies analysis between dynamic features registered by tablets. These complex features are then used to create vectors describing the signature. Elements of these vectors are calculated using measures proposed in this work. The similarity between signatures is assessed by determining the similarity of vectors in the compared signatures. Research, whose results will be presented in the further part of this work, have shown a high efficiency of verification using proposed method.

Opis:

The archaeological site in Michałowice is located in south-eastern Poland within the Świętokrzyskie Voivodeship, Czarnocin commune. It is thus far the only known site with over a dozen excavated groove-type burials attributed to the Roman Iron Age of the Przeworsk Culture.In 2010 a small geophysical test survey was commissioned encompassing an area of 50×30m. Amongst the many geophysical techniques available for such an investigation, the magnetic method was chosen. The aim of the survey was first of all to test whether the local archaeological features that were assumed to exist within the site, such as groove-type square burial enclosures, urn graves and possible settlement pits or even anthropogenic sediments, would generate a clear, interpretable geophysical anomaly. For this purpose a Bartington Grad601-Dual fluxgate gradiometer was used. Data was collected in parallel traverses with 1×0.12m sampling and within one 30×30m and one 20×30m grid. The systematic analysis and mapping of the anomalies registered with magnetic prospecting confirmed the presence of buried archaeological structures, revealing new details of the Michałowice sepulchral complex. Although the study area was relatively small, the amount of new information acquired from the survey was overwhelming. What came as a surprise is that all of these anomalies were located in an area presumed to be a peripheral part of the archaeological site. Thanks to the experiences of the 2010 survey, the capabilities of the magnetic method on this specific site have been thoroughly investigated and evaluated positively. For now, a basic modus operandi for interpreting magnetic data for Michałowice has been created, which hopefully will serve as a roadmap or reference for future integrated non-invasive approaches in the region.

Opis:

The analysis of the 19th-Century rendition of „Little Office” indicated that in comparison to the contemporary text of the devotion the religious language has not undergone major changes. In the historical text there are only a few features not present in contemporary prayers. These include: – é in affixes -éj in singular genitive and in affix -ém in singular instrumental and locative cases in the adjectival and pronoun declension; – differences in creating past participle with suffixes -one, today inflected as -ęte; – affix ą in singular accusative of feminine nouns, today inflected as -ę; – affix -m in first-person plural verbs, today inflected as -my. Similarly, vocabulary that today is classified as archaic has been preserved in contemporary prayers. The immutability of religious language is one of its fundamental features that has been in force in the Catholic Church until the Second Vatican Council.

Opis:

The aim of the article is to show the correlation between the subject-participatory paradigm and the basic features of qualitative pedagogical research in practical terms. The choice of this research topic can be justified by the insufficient range of literature in the field. Therefore, the subject-participatory paradigm will be explored from the personalistic perspective, with reference to the constitutive features of pedagogical qualitative research in order to address the research problem while taking into account the above-mentioned correlation. The starting point is the concept of the subject-participatory paradigm grounded in the thought of Karol Wojtyła. Then, in conducting a hermeneutic analysis, the author refers to the concepts of scientists such as Dariusz Kubinowski, Krzysztof Szmidt, Marcella Kelly, Maura Dowling, Michelle Millar, Matthew de Carlo, and others. Also, references are made to the research stages, mainly embedded in the creative methodology, which can facilitate the emergence of the correlation between the aforementioned paradigm and the constitutive features of pedagogical qualitative research.

Opis:

The current reality is saturated with intelligent telecommunications solutions, and automatic speaker recognition systems are an integral part of many of them. They are widely used in sectors such as banking, telecommunications and forensics. The ease of performing automatic analysis and efficient extraction of the distinctive characteristics of the human voice makes it possible to identify, verify, as well as authorize the speaker under investigation. Currently, the vast majority of solutions in the field of speaker recognition systems are based on the distinctive features resulting from the structure of the speaker's vocal tract (laryngeal sound analysis), called physical features of the voice. Despite the high efficiency of such systems - oscillating at more than 95% - their further development is already very difficult, due to the fact that the possibilities of distinctive physical features have been exhausted. Further opportunities to increase the effectiveness of ASR systems based on physical features appear after additional consideration of the behavioral features of the speech signal in the system, which is the subject of this article.

Despite high number of works in this area, the investigations on the logic structure of the databases used for the storage and processing of manufacturing features are very limited. The paper presents the logic level of the object database oriented on manufacturing features. This level consists of four layers: topics, structures, attributes and methods. Each of these layers is discussed and illustrated with the examples taken from the workpiece modeling subsystem of rotational parts with non-rotational features.

Opis:

Growing intensity of marine transport results in the increase of the amount of oil pollution released into the sea water. The presence of oil in the sea, which is thought to have come from accidental spills or tanker disaster, is connected mainly with the daily operation of marine engines. Pollution from ships engines, can reach the sea water masses together with ballast or bilge water as the result of human error or a failure of marine equipment. This paper is focused on a comparison of the optical properties of marine waters and oil substances. These include the spectra of absorption coefficient, spectra of scattering coefficient and scattering phase-function (for different wavelength) which describes an angular distribution of scattered light intensity in the sea water. The light scattering phase function depends on the water constituents like mineral suspensions, zooplankton and phytoplankton cells, gas bubbles or so-called yellow substances as well as oil droplets of water pollution. Detection of oil substances in the sea can be effective when it is done remotely, from ships, buoys, inshore or offshore towers, the decks of aircraft or satellites. The knowledge of the listed above properties of natural (clean) seawater is necessary, because they determine the field of light coming out from the sea and allow interpret images of sea surface from point of view of crude oil and the petroleum products detection. In this study we also discuss optical contrast of oil residuals in the sea in various sea regions.

Opis:

The automatic recognition of signal types is an important task of monitoring receivers and also cognitive receivers. Several modulation recognition or classification procedures exist for single channel signal types while a simple robust procedure for automatic recognition of OFDM signals is lacking because of its numerous frequency channelslying close together. The task considered in this paper is the discrimination between OFDM (or multi-channel) signals and other signal types. The number of frequency channels of the OFDM signals is assumed to be unknown a priori. So, together with the automatic OFDM detection the estimation of the number of frequency channels is treated. Several discrimination features have been examined and the most promising ones are described: measures of the variation, of the skewness, of the kurtosis, and of the specific picket-fence shape of the spectrum which is typical for many OFDM signals. For a number of real-world OFDM samples, recorded from the high frequency range, results are presented. An automatic discrimination from single channel or noise like signals is achieved and the number of system channels can be estimated.

Opis:

In automatic and accurate reading recognition of analog meters based on machine vision, one of important issues is the detection of pointer features, which includes the meter center and pointer image processing. The current automatic-recognition approaches to reading analog meters often consist in locating the meter center based on the dial region or its border. The located center is not coincident with the rotation center of pointer which leads to inevitable reading errors. In the paper, the centripetalism of annular scale lines is used to calculate the position of the pointer rotation center. First, it uses the region growing method to locate the dial region and uses the eccentricity measure to extract annular scale lines. Second, the parameters of these scale lines are estimated with the Hough transform method. Then, the common intersection of a group of lines, i.e., the meter rotation center, is determined with the maximum probability criterion. Finally, the pointer centerline and direction are detected through the calculated center and the Hough transform results. The simulated and experimental results demonstrate that the proposed method can accurately locate the pointer rotation center and obtain pointer centerline. Moreover, it is applicable to the meter image captured under a slant camera view or with uneven light illumination.

Opis:

W pracy przedstawiono zagadnienia związane z modelowaniem i optymalizacją generatora cech dla systemu automatycznego rozpoznawania mówcy (ang. Automatic Speaker Recognition - ASR). Etap generacji cech (parametryzacji sygnału mowy) jest fundamentalny w tego typu systemach, z uwagi na fakt, że unikatowy wektor cech ma decydujące znaczenie w procesie rozpoznawania. Zadaniem generatora cech jest opisanie sygnału mowy za pomocą możliwie mało licznego zbioru deskryptorów, bez utraty informacji istotnych z punktu widzenia rozpoznawania mówcy. Ponadto parametryzacja powinna wykazywać odporność na warunki akustyczne i techniczne rejestracji oraz na zawartość lingwistyczną rejestrowanego materiału. Badania przedstawione w referacie koncentrowały się przede wszystkim na wielokryterialnej optymalizacji wybranych parametrów generatora cech opartego na analizie cepstralnej, uwzględniającej dodatkowo selekcję cech. Oceny otrzymanych wyników dokonano w oparciu o analizę składników głównych (ang. Principal Component Analysis - PCA) zbioru deskryptorów wyznaczonych dla próbek głosu pochodzących od 24 mówców.
The paper presents issues related to modeling and optimization of the features generator for the speaker recognition system (ASR - Automatic Speakers Recognition). Parameterization's stage of the speech signal (features generation) is fundamental in this type of systems, due to the fact that the unique vector of features is crucial in the process of recognition. The task is to describe the speech signal using descriptors as little as possible, without loss of relevant information to the speaker recognition. In addition, parametrization should have robust to acoustic and technical registration conditions and the recorded linguistic material. The research presented in this paper is focused primarily on the multicriteria optimization of selected parameters of the features generator based on cepstral analysis, additionally allowing features selection. Finally, evaluation of the results was based on the analysis of main components, a set of descriptors for the samples voice acquired from 24 speakers.

In this paper, a new method based on color features of microscopic image and least-squares support vector regression model (LS-SVR) is proposed for indirect measurement of copper concentrate grade. Red, green and blue (RGB), hue and color vector angle were extracted from color microscopic images of a copper concentrate sample and selected for the comparison. Three different estimation models based on LS-SVR were developed using RGB, hue, and color vector angle, respectively. A comparison of three models was carried out through a validation test. The best model was obtained for the hue giving a running time of 30.243 ms, root mean square error of 0.8644 and correlation coefficient value of 0.9997. The results indicated that the copper concentrate grade could be estimated by the LS-SVR model using the hue as input parameter with a satisfactory accuracy.

Opis:

Facial feature analysis is a basis examination in everyday orthodontics practice. Traditionally it was carried out using the patients photographs and callipers. Although the devices for scanning 3D surfaces have been developed since last decade of XX century their use in supporting orthodontics diagnosis have been limited due to availability and prices. The present work examine the possibility of usage of the 3D surface scanning for orthodontics purposes using professional graphic tool RapidForm. The landmarks-based analysis of facial features and asymmetry of soft tissue is described. Possibilities of surface-based analysis are also illustrated and their limitations are discussed.

Opis:

This study investigated the effects of user factors and cognitive sign features on the guessability of mine safety signs. Sixty naive participants guessed the meanings and rated the cognitive sign features of 42 Mainland Chinese mine safety signs. The results showed that some user factors were significant predictors of guessing performance, while some were not. As expected, guessability scores varied significantly with the cognitive sign features of familiarity, concreteness, simplicity, meaningfulness and semantic closeness. The findings emphasize the need to create awareness of the importance of mine safety and promote understanding of mine safety sign meanings amongst people in their work environments. To design more user-friendly mine safety signs, industrial designers should develop and evaluate signs with consideration of the significant user factors and the 5 sign features tested here.
