WATERFLOOD EFFICIENCY ASSESSMENT USING REGRESSION ANALYSIS

For quick waterflood efficiency assessment at oil fields, methods of visual analysis of the operating indicators of production and injection wells without calculating its quantitative characteristics are widely used. Thus, the development of analytical methods for calculating the effectiveness of measures taken on the injection wells is an urgent task.
 The aim of the work is to improve the quality of the waterflood management process by developing an algorithm for quick assessing the additional oil production from geological and technical activities at injection wells.
 To achieve this aim, regression analysis methods, genetic optimization methods, and methods of mathematical modeling of operating indicators using decline curves and displacement characteristics were used.
 The authors proposed an algorithm for quick assessing the effectiveness of injection sites, which allows, using Data Science methods, to quantify additional oil production after carrying out geological and technical measures at injection wells.

Commemoration as a form of representation of the Holocaust in the cultural space of Ukraine in the XXI century

The relevance of the article. Commemoration1 of the Holocaust2 is a practice that is the quintessence of the memory of the Jewish past and a promising approach for comprehension of collective experience. Successful realization of forms of remembrance is actively implemented in the main historical centers associated with Jewish history: Poland, Hungary, Germany, and others. It is there that commemorative practices have become an integral part of the multicultural dimension. For a long time, the national focus of Holocaust remembrance was regulated by political mechanisms post-Soviet space, depriving society of the opportunity to expand the functionality of commemoration. This influenced the presentation of the perpetuation of the tragedy and the formation of self-identity among Ukrainian Jews.
 The purpose of the research. The article presents an examination of individual examples of modern Holocaust commemorative practices and their impact on the cultural space of Ukraine. The dynamics of urban, visual and memorial aspects of commemoration are identified and analyzed, and their specifics are outlined.
 The methodology is based on the use of the following methods: historical and cultural methods, which were used to characterize the peculiarities of Jewish cultural memory within the framework of the Holocaust representation; sociological method of visual analysis, which was used to study the specifics of commemoration practices using examples of commemoration; structural and semiotic methods, which were used to determine the relationship between individual and collective reflection within the memorial space, and to outline the specific symbolism of the tragedy. It is determined that the rethinking of the tragedy of the Jewish people is the result of rethinking the Holocaust in society. This became possible due to the intensification of research into the meaning of the tragedy.
 The results. It is proven that by reconstructing the image of the past in the sociocultural dimension, it becomes possible to deprive the Jews of local perception and focus on building intercultural communication through the prism of a positive trend in preserving and restoring memory.
 The scientific novelty of the research. Іs presented in the analysis of examples of Holocaust commemoration in Ukraine and the identification of the constituent elements of the cultural space of remembrance.
 The practical significance. The prospect of a further vector of research is the practical implementation of the theoretical material for creating projects dedicated to the tragedy and Jewry in the national territory.
 Conclusions. Having carried out a cultural analysis of illustrative examples of Holocaust remembrance, we can draw the following conclusions. Firstly, in the course of the study, we determined that the urban perspective of the Holocaust commemoration, together with the elaboration of the trauma of witnesses, aims to create a tendency to perceive the «other». We believe that this is a mentally necessary strategy for Ukrainian realities. Secondly, we have generalized that commemoration focuses on creating an individual experience of perceiving the tragedy of the Holocaust, making it unique. We argue that a complex conglomerate of feelings, which concentrate visual forms, will allow everyone to find their place in this event, discover its leitmotifs, and construct the context of the future with a clear understanding of the cyclical nature of history. Thirdly, memorial commemoration is the most accessible for reflection. However, the places of memory executions are not without variability in interpretation and are an example of a primary source that makes it possible to study of the Holocaust.

A Review of the Blast Fragmentation Analysis Techniques used in Surface Mines

Fragmentation refers to the process of breaking solid in-situ rock masses into smaller pieces during excavation or material handling operations. The fragment size distribution and degree of fragmentation within the blasted rock mass stand as a critical aspect for optimizing the efficiency of loading, transportation, crushing, and milling operations. The analysis of blast fragmentation analysis is done by several existing modern techniques which include the visual analysis method, photogrammetric method, and image analysis method, etc. In this study, all the blast fragmentation techniques are reviewed, and the advantages and disadvantages of all the methods are discussed. Along with that, a blast fragmentation analysis is conducted for the rock pile images of a blasting site collected from Dongri Buzurg Mine (MOIL), India using the image processing technique in WipFrag software. The feasibility of the blasting patterns is judged based on the uniformity coefficient (Cu) and the coefficient of gradation (Cg) which are found to be 4.47 and 0.94 respectively. The fragmentation for the muck pile is found to be uniform and well-graded for the blast site and the methodology used is found to be simple yet effective for the analysis.

DOMINO: Visual Causal Reasoning With Time-Dependent Phenomena.

Current work on using visual analytics to determine causal relations among variables has mostly been based on the concept of counterfactuals. As such the derived static causal networks do not take into account the effect of time as an indicator. However, knowing the time delay of a causal relation can be crucial as it instructs how and when actions should be taken. Yet, similar to static causality, deriving causal relations from observational time-series data, as opposed to designed experiments, is not a straightforward process. It can greatly benefit from human insight to break ties and resolve errors. We hence propose a set of visual analytics methods that allow humans to participate in the discovery of causal relations associated with windows of time delay. Specifically, we leverage a well-established method, logic-based causality, to enable analysts to test the significance of potential causes and measure their influences toward a certain effect. Furthermore, since an effect can be a cause of other effects, we allow users to aggregate different temporal cause-effect relations found with our method into a visual flow diagram to enable the discovery of temporal causal networks. To demonstrate the effectiveness of our methods we constructed a prototype system named DOMINO and showcase it via a number of case studies using real-world datasets. Finally, we also used DOMINO to conduct several evaluations with human analysts from different science domains in order to gain feedback on the utility of our system in practical scenarios.

PRESENTATION OF RISK AND RISK PERCEPTION IN INSURANCE ADVERTISEMENTS IN TURKEY: THE CASE OF 1963 HAYAT MAGAZINE

In parallel with the development of the insurance sector in Turkey, there has been an increase in the number of print advertisements. This increase has been reflected in the content of advertisements in direct proportion to the development of both the insurance sector and the advertising sector. It is possible to see the traces of this development, especially in the presentation of risk and risk perception in advertisements. This study aims to reveal how insurance advertisements presented risk and risk perception to the public in the past. Insurance advertisements published in Hayat Magazine in 1963 were selected through convenience sampling. Then, common codes were extracted from the advertisements through content analysis conducted independently by two researchers. The advertisements emphasizing risk and risk perception presented with any visuals were determined by criterion sampling from purposive sampling methods and 3 advertisements meeting these criteria were analyzed by both content analysis and visual semiotics analysis methods. Within the framework of its limitations, the research highlights two main themes in the presentation of risk and risk perception in insurance advertisements: 1- Risk and risk perception are presented to society with content based on fear of the future. 2- The contents mostly emphasize socio-cultural elements and life practices.

William Hanna and Joseph Barbera’s creation Tom & Jerry is widely regarded as one of the greatest animated series of the 20th century. This iconic series is evidence of the lasting appeal of animation and its ability to captivate viewers for decades.With its innovative approach to visual storytelling, timeless humour, endearing characters, and most notably its artistic use of defamiliarization technique, Tom & Jerry has left an indelible mark on the animation industry, providing amusement to viewers of all ages around the world and firmly soldifying its status as a true masterpiece. Based on the visual analysis method, this paper adapts Shklovsky’s technique of ‘defamiliarization’ from the field of literature to the domain of media studies, explaining its different facets and exploring its practical implications. By transcending the boundaries of its original literay context, this paper aims to throw light on the many ways in which defamiliarization manifests itself in Tom & Jerry animated series and how it has a big impact on getting viewers to change their habitual reactions to artwork and instead percieve it in a fresh, vivid, and intense way.

Prospective Study to Analyze the Concordance Between a Standardized Visual Method With Pathology to stratify Nonalcoholic Fatty Liver Disease in Cadaveric Liver Grafts Evaluated for Transplantation.

The main challenge of liver transplantation is the discrepancy in demand and availability. Marginal grafts or full organs from donors with expansion criteria have been considered to reduce the shortage and assist a greater number of patients. Nonalcoholic fatty liver disease (NAFLD) is one of the most important defining criteria for expanded criteria organs. The present study proposes that an organized visual analysis method could correctly identify and classify NAFLD and organ viability without the need for liver biopsy and its logistical concerns. Pictures from the grafts were taken at a standardized method (same distance, light conditions, and register device) before and after the perfusion. The visual liver score (VLS) was applied by transplant surgeons; biopsies of the grafts were analyzed by a pathologist in a double-blind design. Score performance and interobserver agreement for NAFLD detection and grading, as graft viability evaluation, were calculated. Fifty-seven grafts were analyzed. At least 1 previous expansion criterion was presented by 59.64% of donors. The prevalence of NAFLD was 94.73%, with 31.57% borderline nonalcoholic steatohepatitis and 5.26% nonalcoholic steatohepatitis. Steatosis was identified with 48.68% (preperfusion) and 64.03% (postperfusion) accuracy. NAFLD stratification was performed with 49.53% (preperfusion) and 46.29% (postperfusion) accuracy. Viability related to NAFLD was identified with 51.96% (preperfusion) and 48.52% (postperfusion) accuracy. Interobserver agreement was moderate for total VLS and poor for individual components of VLS. Although a standardized method was not reliable enough for visual evaluation of NALFD compared with pathology, efforts should be made to expand access to biopsy. Further studies are needed to understand whether the VLS needs to be adapted or even excluded in the liver transplant scenario, to assess the importance of ectoscopy related to posttransplant clinical outcomes, and to determine its role in graft selection.

Effective dose and image quality for different patient sizes during AP upper abdominal radiography: A phantom study

IntroductionUndertaking medical imaging examinations on obese patients can present practical challenges. Choosing optimal imaging protocols can be difficult, especially when promoting the ALARA principle. The aim of this study was to assess the effects of increasing body part thickness on image quality (IQ) and effective dose (ED) during upper abdominal radiography. A secondary aim was to determine the optimum exposure settings for larger sized patients. MethodsUnderweight, standard, overweight and obese abdomen sizes were simulated using an anthropomorphic upper abdomen phantom, without and with additional fat layers (6, 10 and 16 cm). Phantoms were imaged using a variety of tube potentials (70–110 kVp), automatic exposure control (AEC) and a source-to-image distance of 120 cm. IQ was assessed visually using a relative visual grading analysis (VGA) method. Radiation dose was evaluated by calculating the ED using the Monte Carlo PCXMC 2.0 computer program. ResultsIQ values showed a statistical reduction (p = 0.006) with increasing phantom size across all examined tube potentials. The highest IQ scores (3.3, 2.8, 2.5 and 2.2, respectively) were obtained at 70/75 kVp for all phantom thicknesses. As tube potential increased the IQ was also shown to decrease. ED showed a statistically significant increase (p < 0.001) with increasing phantom thicknesses. ConclusionHigher EDs were evident when applying lower tube potentials. Using an AEC with high tube potentials (105/110 kVp) can lead to a considerable decrease in ED with acceptable IQ when undertaking upper abdomen radiography on patients with large body part thicknesses. Implication for practiceApplying higher values of tube potentials for patients who have a thicker abdomen can lead to decreased ED.

Online Incivility and Contextual Factors: Data‐Driven Detection and Analysis

ABSTRACTUncivil behaviors like rude or hate speech have been a persistent problem on social media, which could lead to negative user experience or even affect the psychological well‐being of users. Automatic detection and moderation of such behaviors are critical to creating a supportive online community for effective user communication and positive user experience. In this tutorial, we propose methods to study online incivility, which includes data collection from a social media platform, i.e., Reddit, automatic detection of incivility with pretrained deep learning classifiers, and statistical and visual analytical methods to investigate the combination of community characteristics and users’ interactive patterns that relate to the occurrences of incivility. Similar methods can be applied to understand other information misbehaviors online, such as misinformation, dissemination of rumors, and cyberstalking. This panel is sponsored by SIG SM.

Experimental study on tracing the initial water–to-cement ratio of hardened concrete using petrography analysis

This study was performed to experimentally track the initial water-to-cement (w/c) ratio of hardened concrete by visualizing capillary porosity. The specific objective is to evaluate the accuracy of various image processing methods to investigate the fluorescence intensity of dyed epoxy resin infiltrated capillary pores as a way to trace the initial w/c ratio. The epoxy resin was infiltrated into cement paste, mortar, and concrete with different w/c ratios, and thin section images of those samples were prepared. The fluorescence intensities of the samples were quantitatively analyzed by applying Otsu, triangular, and mean methods to histogram data. A proportional relationship was established between the quantified fluorescence intensity and the designed w/c ratios of the paste, mortar, and concrete samples. Accuracy was validated by comparing histogram analysis with a visual analysis method, and the most suitable method for evaluating the initial w/c ratio was proposed.

A Sun that Never Sets: Eastern Cherokee Tattoo Artist John Henry Gloyne and the Aesthetics of Reimagining

Abstract: This article examines a selection of work by contemporary tattoo artist John Henry Gloyne (Eastern Band of Cherokee Indians) to understand how tattooing functions as an Indigenous creative practice that can imagine alternative realities and reestablish connections to Native pasts and presents. Gloyne's work redefines contemporary Native tattooing by highlighting its continuing significance and artistic innovations in the present. In doing so, Gloyne's work challenges the settler notion that Native cultural practices are static and stuck in the past. The authors' analysis includes Gloyne's reinvention of Cherokee symbols (water spider and Booger mask tattoos), early/mid-twentieth-century Americana tattoo flash, and his tattoo-inspired painting Sacred Realms: Tobacco Offerings to the Picture Machine . Honma and Francoso employ an analytic of "reimagining" to investigate how Gloyne's work embraces an ethos of experimentation and innovation that moves beyond settler frameworks of comprehension. In order to understand how he challenges various modes of representation and ways of looking that normalize the settler project, they historicize the symbols and motifs found in Gloyne's work. They incorporate interdisciplinary methods of visual analysis, historical recontextualization, and interview data to center Gloyne's unique aesthetic approach, which foregrounds renewed ways of envisioning and embodying Indigenous worlds.

Fashion on Currency: Analysis of the 1977 – 1986 Millinery Fashion in Post-independence Ghana

This article showed interest in millinery displayed pictorially on the currencies as well as the significance of those fashion representations in Ghana’s fashion culture. The article specifically analysed the millinery fashion that featured on currency notes of 1977 and 1986 and the Yaa Asantewaa’s imagery on the currency note of 1984. Three Ghanaian currencies purposively sampled for the study were the Five Cedis note issued on July 4, 1977; the Fifty Cedis note issued on 15th July 1986; and the Twenty Cedis note issued on 15th May 1984. These currency notes were released within nine years interval, that is, between 1977 and 1986. Content analysis of visual images, and social semiotics methods of visual data analysis constituted the method of analysis for the study focusing on the dominant feminine figures on the currency accessorised with millineries. The study put forward those feminine images represented on the Five Cedis, Fifty Cedis, and Twenty Cedis currency notes issued on July 4, 1977, 15th July 1986, and 15th May 1984 respectively that displayed the repertoire of straw-woven and the Akan militaristic millinery fashion in post-independence Ghana. The millinery practices depicted on the currencies embodied historical allusions to Ghanaian women irrespective of economic background and ingrained in the memory of the citizenry the fashioned feminine identities constructed through millinery fashion in relation to the popular culture of twentieth-century Ghana. The selected indigenous millinery-inspired visuals also celebrated female vitality and brought to the fore the visibility of women in the public sphere and represented the epitome of independent women of twentieth-century Ghana who contributed to national development. It also made a strong socio-political fashion statement about the indigenous classic millinery fashion consciousness of Ghanaians and the millinery structural design in use in the post-independence era.
