The Creation of Death-Worlds: Visual Necropolitics and Russia’s War on Ukraine

With the continuous advancement of autonomous driving technology, visual analysis techniques have emerged as a prominent research topic. The data generated by autonomous driving is large‐scale and time‐varying, yet more than existing visual analytics methods are required to deal with such complex data effectively. Time‐varying diagrams can be used to model and visualize the dynamic relationships in various complex systems and can visually describe the data trends in autonomous driving systems. To this end, this paper introduces a time‐varying graph‐based method for visual analysis in autonomous driving. The proposed method employs a graph structure to represent the relative positional relationships between the target and obstacle interferences. By incorporating the time dimension, a time‐varying graph model is constructed. The method explores the characteristic changes of nodes in the graph at different time instances, establishing feature expressions that differentiate target and obstacle motion patterns. The analysis demonstrates that the feature vector centrality in the time‐varying graph effectively captures the distinctions in motion patterns between targets and obstacles. These features can be utilized for accurate target and obstacle recognition, achieving high recognition accuracy. To evaluate the proposed time‐varying graph‐based visual analytic autopilot method, a comparative study is conducted against traditional visual analytic methods such as the frame differencing method and advanced visual analytic methods like visual lidar odometry and mapping. Robustness, accuracy, and resource consumption experiments are performed using the publicly available KITTI dataset to analyze and compare the three methods. The experimental results show that the proposed time‐varying graph‐based method exhibits superior accuracy and robustness. This study offers valuable insights and solution ideas for developing deep integration between intelligent networked vehicles and intelligent transportation. It provides a reference for advancing intelligent transportation systems and their integration with autonomous driving technologies.

Loneliness:Black Gay Longing in the Work of Essex Hemphill Darius Bost (bio) Do you think I could walk pleasantlyand well suited toward annihilation?with a scrotal sack full of primordial lonelinessswinging between my legslike solid bells? —Essex Hemphill Black gay poet, essayist, and performer Essex Hemphill was, arguably, the most prominent of the black gay intellectuals of the 1980s and early 1990s. His work addresses the psychological, social, and political struggles of urban black communities, and often maps the psychological, social, and political location of black gay men onto the black urban landscape. In "Heavy Breathing," Hemphill takes the reader on a city bus ride through 1980s black Washington, DC. The speaker of the poem rides the "X2, the bus I call a slave ship," with the "majority of its riders Black" (lines 65–66). The speaker defines the "X2" as a "risky ride," with its "cargo of block boys, urban pirates" (71–72). The imagery of the city bus as "a slave ship" and the riders as "cargo" conjures the historical trauma of the Middle Passage, suggesting a continuity between the social death of antebellum slavery and the urban poverty and decay produced by neoliberal capitalism. The speaker goes on to describe the spectacular forms of violence that emerged in Washington, DC, in the late '80s and '90s, as the line "the funerals of my brothers" alludes in part to how the nationwide crack epidemic greatly impacted crime in cities like Washington, DC, with a homicide rate so high in the late 1980s and early 1990s that it eventually earned DC the label of "murder capital."1 But the speaker attends these funerals only "at the end of heavy breathing" (63), signaling the climax of public sexual encounters with other men. It is in this same black urban [End Page 353] environment that the speaker negotiates the dangers and pleasures of same-sex desire. If read within this context, the speaker's "brothers" are also his same-sex-desiring brothers, and the "funerals" are also for those who have succumbed to homophobic violence and AIDS. A range of black cultural studies scholars, most notably Frank Wilderson and Jared Sexton, have also theorized a continuity between antebellum slavery and contemporary blackness.2 Drawing on Orlando Patterson's conceptualization of antebellum slavery as "social death" and Saidiya Hartman's conception of "slavery's afterlife," these theorists point out the specificity and ubiquity of antiblackness obscured by hegemonic discourses of multiculturalism and colorblindness in the late twentieth and twenty-first centuries.3 Furthermore, Sexton defines the lived experience of blackness as a "social life of social death" and expresses a political refusal to distance himself from blackness "in a valorization of minor differences that bring one closer to health, life, or sociality."4 But these theories have yet to fully account for gender and sexual difference for the queer "brothers" of Hemphill's poem, who also negotiate their lives under the sign of blackness. In Wilderson's formulation, queerness, as a "human" ontological category, depends on the non-ontology of blackness for its coherence, and, thus, the gratuitous violence done to black queer and transgender bodies is subsumed under the structures of anti-blackness. But afro-pessimist theories fail to address how non-normative black genders and sexualities signify differently, and how these so-called "minor differences" oftentimes bring black gender and sexual minorities closer to illness, death, and social exclusion under regimes of antiblackness. The line "funerals of my brothers" in Hemphill's poem conjures the ghostly presence of 1980s and 90s black gay intellectuals within contemporary theorizations of blackness fixed as pathology and as embodied subjectivity marked by (social) death. In addition to the racial retrenchment affecting urban black communities in the Reagan era, black gay artists, intellectuals, and activists in the 1980s and 90s also experienced amplified cultural stigma attached to homosexuality during the AIDS epidemic. Many of them carried in their bodies the literal pathology of AIDS and a consciousness shaped as much by everyday black life as it was by black (social) death. Though the literary communities that they formed could not prevent their deaths, nor could they alleviate the debilitating psychic and...

This article presents a summary of research conducted on the visual representation of indigenous cultures in four English textbooks produced for lower secondary schools with the aim of investigating the extent to which images of indigenous people contribute to, or contradict, the general cultural aims of the English language learning curriculum in Norway. Over 800 textbook images were analyzed using the methods of visual content analysis and semiotic image analysis. A qualitative analysis of two photomontages also provides a more holistic approach to the study and helps to more clearly explain the quantitative results. The results from the research show a strong trend to focus on traditional aspects of indigenous people, a tendency to represent indigenous people in a lower position of power than the viewer, and to distance the viewer. Comparatively, the images of white people more frequently invite the viewer to interact and empathize with the participants. Consequently, the research concludes that the images in the four EFL textbooks analyzed are, to a large degree, potential carries of ideologies in direct contradiction to the general cultural aims of English language learning in Norway. The implications of these findings are that images and how they position readers should be a part of EFL teaching.

Visual analysis of architectural landscape plays an important role in the urban construction process. This paper using virtual reality technology, constructed the 3d scene of urban architectures. And the simulation system provides the intuitive, convenient analysis tools and methods for visual analysis. Some vision quantitative issues about geometry space and color space of architectural landscape were elaborated.

The analysis models were integrated into the simulation software system, so as to realize the 3d visualization of visual quantitative analysis. Considering the influence of planning control factors, at the end this paper put forward a comprehensive evaluation method of architectural landscape visual analysis.

Visualization and visual analysis play important roles in exploring, analyzing, and presenting scientific data. In many disciplines, data and model scenarios are becoming multifaceted: data are often spatiotemporal and multivariate; they stem from different data sources (multimodal data), from multiple simulation runs (multirun/ensemble data), or from multiphysics simulations of interacting phenomena (multimodel data resulting from coupled simulation models). Also, data can be of different dimensionality or structured on various types of grids that need to be related or fused in the visualization. This heterogeneity of data characteristics presents new opportunities as well as technical challenges for visualization research. Visualization and interaction techniques are thus often combined with computational analysis. In this survey, we study existing methods for visualization and interactive visual analysis of multifaceted scientific data. Based on a thorough literature review, a categorization of approaches is proposed. We cover a wide range of fields and discuss to which degree the different challenges are matched with existing solutions for visualization and visual analysis. This leads to conclusions with respect to promising research directions, for instance, to pursue new solutions for multirun and multimodel data as well as techniques that support a multitude of facets.

Semiotics is a branch of science that includes the processes of examining, interpreting and re-interpreting signs with the system of "Signifier", "Signifier", "signified". In semiotic analysis, besides the direct messages, the messages that are wanted to be conveyed indirectly are revealed. In this article, it is aimed to examine 10 randomly selected Doodle illustrations from the Doodle archive of 2022 using Barthes' semiotic analysis method. Azah Aziz's birthday, Indonesian Independence Day, Japan's Mountain Day, Kimiko Tsumura's 120th birthday, India Independence Day, Doodle designed for “Google”, Seiki Kuroda's 156th birthday, Qixi Festival, Luisa de Medrano's 538th birthday, Singapore National Day illustration works are analyzed. In the article, literature review was used to obtain theoretical information about Doodle illustration works, and Barthes' semiotic analysis method was used for the analysis of randomly selected Doodle illustration works. While the Google company used to publish Doddles only for important days, today it has gone to design diversification in different categories; It includes designs in its corporate image for birthdays of famous people, holidays, festivals, special days of countries (independence day, mountain day, etc.), national days as animation and video content, not just visuals. It has been concluded that the birthdays of famous people, independence days of countries, mountain days, festivals, national days are thematically analyzed in Doodle studies, which are analyzed semiotically. It is noteworthy that typographic arrangements are frequently used in Doodle works, and that typographies are deformed and adapted to the design in an integrated manner with the visual. It has been concluded that the use of color directly reflects the subject it deals with or the characteristics of the culture it represents, and that Doodle impersonates the theme in the context of technical and color use.

Introduction: The aim was to examine the differences in electroencephalography (EEG) findings by visual and automated quantitative analyses between Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD). Methods: EEG data of 20 patients with AD and 24 with DLB/PDD (12 DLB and 12 PDD) were retrospectively analyzed. Based on the awake EEG, the posterior dominant rhythm frequency and proportion of patients who showed intermittent focal and diffuse slow waves (IDS) were visually and automatically compared between the AD and DLB/PDD groups. Results: On visual analysis, patients with DLB/PDD showed a lower PDR frequency than patients with AD. In patients with PDR <8 Hz and occipital slow waves or patients with PDR <8 Hz and IDS, DLB/PDD was highly suspected (PPV 100%) and AD was unlikely (PPV 0%). On automatic analysis, the findings of the PDR were similar to those on visual analysis. Comparisons between visual and automatic analysis showed an overlap in the focal slow wave commonly detected by both methods in 10 of 44 patients, and concordant presence or absence of IDS in 29 of 43 patients. With respect to PDR <8 Hz and the combination of PDR <8 Hz and IDS, PPV and NPV in DLB/PDD and AD were not different between visual and automatic analysis. Conclusions: As the noninvasive, widely available clinical tool of low expense, visual analysis of EEG findings provided highly sufficient information to delineate different brain dysfunction in AD and DLB/PDD, and automatic EEG analysis could support visual analysis especially about PD.

To compare the visual and semiquantitative analysis of carbon-11-methionine (C-MET) PET/computed tomography (CT) images in patients with primary brain tumors and suspected recurrence, persistence, or necrotic post-therapeutic changes. A total of 41 consecutive C-MET-PET/CT scans on 35 (21 men, mean age 44.1±16.6 years) patients were requested for MRI suspicion of recurrent or persistent primary tumor after therapy. The C-MET PET/CT were obtained 20 min after an intravenous injection of 555-740 MBq (15-20 mCi) of C-MET. Both visual and semiquantitative evaluations were performed comparing C-MET uptake between suspicious areas and different lesion/normal-to-background ratios. The final diagnosis was established by histological examination in 12 cases and clinical and MRI follow-up in 29 cases. Visual analyses were positive in 27 (63.4%) and negative in 14 (36.6%) of the C-MET PET/CT. The sensitivity was 83.9%, specificity was 90.0%, positive predictive value was 96.3%, negative predictive value was 64.3% and accuracy was 71.4%. For the semiquantitative analysis, all the lesion/normal-to-background ratios could differentiate between tumor and nontumor (P<0.001), the lesion/contralateral parenchyma (L/CP) maximum standardized uptake value (SUVmax) being the index with the highest area under de curve (0.938). Applying an L/CP SUVmax index of 1.21, the sensitivity was 89.3%, specificity was 90.0%, positive predictive value was 96.1%, negative predictive value was 75%, and accuracy was 82.9%. C-MET-PET/CT was a useful technique to differentiate post-therapeutic changes from tumor presence in treated patients with brain neoplasm in whom cerebral MRI is nonconclusive, showing a high diagnostic performance. Our results showed only slight differences between visual analysis methods and the L/CP SUVmax ratio, the best of the semiquantitative methods.

The purpose of this study was to evaluate the manual and automatic analysis methods for force-time curve analysis of the isometric mid-thigh pull (IMTP) test. The visual analysis, first derivative analysis and threshold analysis methods were used to analyse onset time and time-specific forces at 50 ms, 90 ms, 200 ms and 250 ms on the force-time curve. Ninety-three collegiate sports athletes’ trials were selected and analysed by each method. The visual analysis method was set as the reference method for paired comparisons with the first derivative analysis method and threshold analysis method. Onset time comparisons revealed that the first derivative analysis method was comparable with the visual analysis method with average difference at about 30 ms. Results from the weighted least products regression analysis and the Bland-Altman analysis showed that large fixed bias confounded by proportional bias existed in the threshold analysis method, and time-specific force variables obtained from the first derivative analysis method were closer to those from the visual analysis method when compared with the threshold analysis method. These findings suggest that the first derivative analysis method could be an effective tool for force-time curve analysis of the IMTP test.

Visual procedures are the most commonly used in the analysis of single case design data. However, a number of problems with visual analysis methods have been identified in previous research, and research and development on visual analysis methods has been recommended. If single case design methods are to be used, as once hoped, by social work practitioners, then visual analysis methods should be easy and quick to use as well as methodologically defensible. This article presents visual analysis methods for use by social work practitioners. First, there is a presentation of a method for representing trend. Next there is a presentation of methods for representing variability, background variability, and overlap and discussion of their use in the visual analysis of single case data. Finally, there are two illustrative data analyses in which these methods are used. The mathematical and statistical bases for these methods are provided in two appendices. The methods presented are quick and easy to use and require nothing more than a pencil or pen and a straight edge for use by practitioners.

Considering large, complex and multi-dimensional marine field data, the general representation and analysis methods based on 2D GIS can not meet the requirements of Ocean Research. For multi-dimensional marine sampling data of sea water properties (ARGO sampling data, ship measured data, etc.), three dimensional interpolation and visual analysis methods can be used to reveal the distribution of sea water properties (such as temperature and salinity), and it is an effective way to detect regional anomaly of marine phenomenon. In order to handle three dimensional sampling data of sea water properties, this paper developed a three dimensional volume visualization analysis GIS component with OpenGL and C++. Three visualization analysis methods are designed and presented, including three-dimensional volume visualization, three dimensional slicing and cutting analysis and three-dimensional contour surface analysis. Example test is conducted, and the test result shows the proposed methods can be effectively used for ocean data analysis.

This study aims to make a visual analysis of each of the films of six artists-directors who received visual arts education and to examine the elements used in the films in the context of visual arts. The artist-directors selected as a sample in the study are Akira Kurosawa, David Lynch, Wong Kar-Wai, Peter Greenaway, Robert Bresson, Andrzej Wajda. These directors were selected with a homogeneous sampling method, one of the purposive sampling methods. In this context, the selected directors have been chosen because they have received visual arts education, the branches of art they are interested in, and have different cultural codes. Visual content analysis, one of the qualitative research methods, was used in this study. The content analysis approach of visual data, which is one of the main methods of analyzing visual materials and data, was used. For this purpose, first, all the films were watched by the researcher, and the image files were arranged in scenes and systematized for examination. The colors used in the resulting movie scenes were visualized in the Procreate program. In addition, the analyzes are philosophically based on the rise and retreat movement that occurs because of the dark and light fighting in Paul Klee's Theory of Colors. A film belonging to each director was examined with the visual analysis method. As a result of the analyzes carried out, it is seen that visual art education has great effects on the use of the color in the films of the directors who receive visual art education. In addition, it has been concluded that in the films of the directors, the narrative has a visual weight and, in these films, which we can call art cinema, photographic images with a linear story are frequently included.

A comprehensive appraisal of perceptual visual complexity analysis methods in GUI design

To establish a large deployable antenna, monitoring and collimation are essential for reliable and precise deployment. We have developed an analysis method to detect shifts in several images, in which the combination of cross-correlations between images and approximations at subpixel precision enables us to detect shifts in images with a precision of up to 0.01 pixels. The LDREX mission; which was a preliminary experiment for a large deployable antenna, ETS-VIII, was performed in December 2000. During this experiment, anomalies occurred in the antenna, and deployment was aborted. To understand the cause of the anomalies, we used our visual analysis method. Using this analysis, we detected vibrating features in the antenna, which were useful for explaining the anomalies. We outline our visual analysis method and discuss its application in monitoring the deployable antenna.
