Opis:
The task of generating fast and accurate three-dimensional (3D) models of objects or scenes through a sequence of non-calibrated images is an active field of research. The recent development in algorithm optimization has resulted in many automatic solutions that can provide an accurate 3D model from texture-full objects. Structure-from-motion (SfM) is an image-based method that uses discriminative point-based feature identifier, such as SIFT, to locate feature points in the images. This method faces difficulties when presented with the objects made of homogenous or texture-less surfaces. To reconstruct such surfaces a well-known technique is to apply an artificial variety by covering the surface with a random texture pattern prior to the image capturing process. In this work, we designed three series of image patterns which are tested based on the contrast and density ratio which increases from the first to the last pattern within the same series. The performance of the patterns is evaluated by reconstructing the surface of a texture-less object and comparing it with the true data. Using the best-found patterns from the experiments, a 3D model of a Moai statue is reconstructed. The experimental results demonstrate that the density and structure of a pattern highly affects the quality of the reconstruction.

Opis:
The paper aims to demonstrate the most important aspects of comparative text analysis based on reporting patterns in TV news both in German and Polish media. The main concern is the cultural background of the texts. The first part of the article concentrates on multimodality of media texts and on the text type ‘TV news’. Following this, the major concepts of the culturality of text types in the pertinent German literature are presented. Against the background of the theoretical founda- tions, upon which the contrastive analysis is built, an exemplary examination is carried out: which ways of multimodal arrangement of TV news concerning terrorist attacks can be discerned? The terrorist attacks in question and which are the topic of the selected TV news took place in Great Britain in the first half of 2017. They were covered by the mentioned TV channels.

Opis:
The experimental material consisted of 15 winter wheat cultivars (14 Polish-bred cultivars and one British cultivar) representing the results of over 100 years of breeding. The cultivars were tested in two-factor field experiments (cultivars were one factor and nitrogen fertilization rates, the other factor) carried out in split-plot design across two consecutive years. This paper demonstrates a combined using AMMI and cluster analyses for effective and efficient estimate of grain-yield response to investigated environments (combinations of 2 years × 3 nitrogen fertilization rates). First, homogenous groups of cultivars were identified in terms of their genotypic profile of AMMI(s) estimates of GEI effects using Ward’s method of cluster analysis. Then, these groups were divided into separate homogenous subgroups with respect to genotype means. The cultivars in each subgroup have a similar grain yield response to the environments and, then, similar adaptation pattern, although the genotype groups differed in adaptation to these environments...

Opis:
Event correlation and root cause analysis play a fundamental role in the process of troubleshooting all technical faults and malfunctions. An in-depth, complicated multiprotocol analysis can be greatly supported or even replaced by a troubleshooting methodology based on data analysis approaches. The mobile telecommunications domain has been experiencing rapid development recently. Introduction of new technologies and services, as well as multivendor environment distributed across the same geographical area create a lot of challenges in network operation routines. Maintenance tasks have been recently becoming more and more complicated, time consuming and require big data analyses to be performed. Most network maintenance activities are completed manually by experts using raw network management information available in the network management system via multiple applications and direct database queries. With these circumstances considered, identification of network failures is a very difficult, if not an impossible task. This explains why effective yet simple tools and methods providing network operators with carefully selected, essential information are needed. Hence, in this paper efficient approximated alarm correlation algorithm based on the k-means cluster analysis method is proposed.

Opis:
Introduction. Dietary pattern analysis is used to describe the dietary habits of a selected population. In many studies, dietary patterns (DPs) have been associated with risk factors for cardiovascular disease (CVD). The aim of the study was to assess the association between dietary patterns identified in the population of Lower Silesia, Poland, with anthropometric and biochemical risk factors for CVD. Materials and method. The study group included 2,025 participants of the Prospective Urban Rural Epidemiological (PURE) Study. Dietary intake was evaluated based on data from the Food Frequency Questionnaire (FFQ). Dietary patterns were derived using principal component analysis (PCA). The relationship between DPs and body mass index (BMI), waist circumference, waist-hip ratio, blood pressure, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides and fasting glucose level, was assessed. Results. Three dietary patterns identified in the study explained 35.6% of total variance. The ‘fruit, vegetables & dairy’ DP, characterized by a high intake of vegetables, fruits, nuts, seeds, raisins, milk and low-fat dairy, was associated with improved lipid profile and anthropometric measures, lower diastolic blood pressure and lower fasting glucose concentration. ‘Traditional’ and ‘fat & sugar’ DPs were unfavourably associated with most of the risk factors for CVD presented in this study. Conclusions. Dietary patterns identified in this study were differently related to selected anthropometric and biochemical risk factors for CVD. ‘Fruit, vegetables & dairy’ DP was favourably associated with the biochemical and anthropometric CVD risk factors, and was characterized by higher nutritional value in comparison with ‘traditional’ and ‘fat & sugar’ DPs.

Opis:
Large software systems need to be modified to remain useful. Changes can be more easily performed when their design has been carefully documented. This paper presents an approach to quickly find design patterns that have been implemented into a software system. The devised solution greatly reduces the performed checks by organising the search for a design pattern as tree traversals, where candidate classes are carefully positioned into trees. By automatically tagging classes with design pattern roles we make it easier for developers to reason with large software systems. Our approach can provide documentation that lets developers understand the role each class is playing, assess the quality of the code, have assistance for refactoring and enhancing the functionalities of the software system.

Opis:
The existing literature, including records of both fossil and extant echinoid encrustation, is quantitatively analysed and reviewed. This shows that echinoid encrustation (number of encrusted echinoid taphocoenoses) has increased nearly continuously and dramatically to the present day, as confirmed by linear regression values of more than 85 per cent. It also demonstrates that current levels of echinoid fouling stabilised by the Miocene, while there has been a more or less continuous record of echinoid encrustation since the Late Cretaceous. Several increases have been identified since echinoid encrustation first noted occurrence from the Late Carboniferous. This trend is explained as the probable result of corresponding increases in productivity (richness, biomass, energetics, ecospace utilisation) and resources in the marine environment, including epibionts and their hosts. This conclusion matches other indicators, including the number and thickness of shell beds, bioerosion and predation intensity or biodiversity. The trajectory might have been altered to some degree by biases (e.g. selective recording, sampling effort, outcrop area, rock volume) in the same way as palaeobiodiversity estimates. Two recognised long-term gaps in echinoid encrustation (Upper Ordovician–Lower Carboniferous and Permian–Lower Cretaceous) are explained in part as bias and as biological and taphonomic signals. These gaps are caused mostly by the rapid disarticulation of Palaeozoic-type echinoids, the methodology applied here, and a lack of interest in the encrustation of Jurassic echinoids. Conversely, three short-term gaps in the Cenozoic are interpreted exclusively as bias. If correct, the present study demonstrates quantitatively the step-wise increase of productivity through time. It also suggests potential focus on further study, including the collection of new data from the field and pre-existing collections, as best for other encrustation proxies (e.g., percent of coverage by epibionts, ratio of encrusted to nonencrusted shells, taxa richness or numerical abundance of sclerobionts) in cases of large-scale analyses.

Opis:
So-called dark patterns are widely discussed in game design. This phenomenon raises concerns for gaming education because numerous dark patterns trick players into real money transactions or gambling. A major obstacle to the practical assessment of the severity of a ‘dark’ pattern is the very definition of ‘game patterns’, basing solely on action-oriented structures. In order to take into account not only abstract expressions of the game system, but also the experience of the player, as well as the diverse contexts in which games are played, this article proposes to use the semiotic model of the ‘ludeme’. A ludeme is a minimal element in game design consisting of a grapheme, an acousteme, and a motifeme. We begin by explaining and situating the conceptual framework of the ludeme theory, with a specific interest in its application to repetitions of the same game element over time and through different digital games. Then, the theoretical framework is applied to SimCity BuildIt and particularly to the ‘dark patterns’ in it. In the last part, paths for further developments of the model of ludemic analysis are discussed, with regard to its relevance for media education and digital game literacy.

Opis:
The Mediterranean Sea has seen an increase of ports hosting cruise ships during the first fifteen years of the 21st century. The increase in cruise ship presence in Mediterranean ports is associated with the dynamism of cruise traffic in recent years, with an average annual growth of 7.45% for cruise passengers worldwide during the period of 1990-2015. Cruise traffic is a maritime business that is primarily composed of two elements, maritime affairs and tourism. This article focuses on the maritime component. With the growth of the cruise industry, cruise lines have been forced to seek new ports to meet demand in an attempt to create differentiated products based on the ports that compose the itinerary. The itinerary system of cruise traffic makes the cruise ports depend on one another to design an itinerary. This feature results in both complex geographic relationships in the design of a cruise itinerary and complex competitive/cooperative relationships between ports. The aim of this article is to present the hierarchic picture of a sample of 29 cruise ports in the Western Mediterranean region during the period of 2000-2015. To achieve this goal, a port size classification is proposed and a shift-share analysis at the inter- and intra-group size level is applied. Moreover, concentration measures are used to determine the changes in the levels of market concentration. Furthermore, a dynamic model is proposed to determine the competitive or cooperative relationships between cruise ports. The proposed model is applied to the largest ports with data from the 2001-2015 period.

Background. Lifestyle factors are the key determinants of health. Diet exerts the great influence on the weight to height ratio and the body fat percentage. In addition to total energy intake, the type and quality of the diet can also play a role in the etiology of obesity in susceptible individuals. Objective. Aim of this study was to identify the dietary patterns of the Polish population and to determine the associations between these characteristics and body composition parameters. This study presents the clustering of dietary models and body composition to determine the association of these dietary patterns with BMI, physique rating (body type) or visceral fat. Material and methods. The sample consisted of 402 respondents aged 18 to 65. Nutrition models were identified with cluster analysis. Logistic regression modelling with adjustment for confounders was applied. Three dietary-lifestyle patterns were identified. Results. Individuals belonging to the processed food model were at significantly higher risk of overweight and obesity expressed by BMI scores (OR=1.55; 95%CI: 1.26-1.89). The average BMI score was 28.19 ± 3.45 kg/m2 in the processed food model, 23.78 ±2.21 kg/m2 in the control group, and 22.17 ± 2.69 kg/m2 in the healthy nutrition model. Respondents belonging to the processed food model were also characterized by considerably higher body fat percentage (OR=1.89, 95%CI: 1.37-2.34) and higher visceral fat levels (OR=2.12; 95%CI: 1.42-2.34). Frequent intake (at least several times a week) of sweetened carbonated or non-carbonated beverages (p=0.002) and instant foods (p=0.006) were the main factors associated with the risk of higher body fat percentage and higher visceral fat levels. Conclusions. Dietary patterns have been proposed as a solution to investigating the association between food choice and body composition, and such studies focus on analyses of the entire diet, rather than on the intake of individual nutrients or food groups.

Opis:
Pursuant to the analysis of the assessment method of the structures of the production process, in the construction of machines, we find that, due to the requirements of diversification of assortments and features of products, criteria of the quality level and work productivity, the reduction of fabrication costs, the structure of the production process develops continuously. Starting from workshops specialized on technological procedures, the structure developed onto production lines in a sole object flow, then onto production lines in a multi-object flow, and, currently, onto flexible production forms. To this purpose, flexible fabrication cells develop. The latter form develops continuously, but especially after the accomplishment of machine-tools with number command. Thus, we pass from production structures in automatic rigid flow lines, efficient for mass and widerange production, to flexible structures, especially efficient in low and medium-range production.
Na podstawie analizy metod oceny struktury procesu produkcyjnego, w konstrukcji maszyn, okazuje się, że ze względu na wymogi dywersyfikacji asortymentu i cechy produktów, kryteria poziomu jakości i wydajności pracy, obniżenie kosztów produkcji, struktura procesu produkcji rozwija się w sposób ciągły. Począwszy od wytwórni wyspecjalizowanych w procedurach technologicznych, z rozwiniętą strukturą na liniach produkcyjnych w przepływie pojedynczego obiektu do linii produkcyjnych z przepływem wielu obiektów, a obecnie do elastycznych form produkcji. W tym celu rozwijają się komórki elastycznego wytwarzania. Ostatnia forma rozwija się w sposób ciągły, zwłaszcza po wykonaniu obrabiarek z poleceniem numerycznym. W ten sposób przechodzimy od struktury produkcji w automatycznych sztywnych liniach przepływu, wydajnych dla masowej i szerokiej zakresowo produkcji, do struktur elastycznych, szczególnie skutecznych w produkcji niskiego i średniego zasięgu.
