LA CYBER-CULTURE: L’IDENTITÉ À TRAVERS LES ÉCRANS BLEUS, ANALYSE DES DISCOURS PROVERBIAUX SUR INSTAGRAM

In the speed of light, digital has invaded our lives, and social networks have become an essential tool of expression and exchange for the majority of citizens of the world, the author Moulessehoul Mouhamed who has always been on the lookout of modernity and new technologies is hardly an exception. This research focuses on the contentious form of discourse in digital spaces. It is more precisely a multidisciplinary analysis: identity, polyphonic and argumentative of this kind of discourse according to the Scandinavian vision of polyphony as well as argumentative theory. Sententious statements serve as support for a personal opinion: to invoke a proverb, a saying or a Koranic verse in one’s speech is to legitimize one’s remarks by opting for other voices which are authoritative on the interlocutor, on the one hand , and to place the latter in a precise discursive framework which conditions its interpretation of the discourse on the other hand. Therefore, the main objective of this article is to emphasize the socio-cultural aspect which remains omnipresent on blue screens by manifesting itself in many representations, despite the rise and development of discourses and ways of expression in the digital age.

РАЗРАБОТКА ПРОГРАММНОГО ОБЕСПЕЧЕНИЯ ДЛЯ АВТОМАТИЗИРОВАННОЙ СИСТЕМЫ ОБРАБОТКИ ВИДЕОМАТЕРИАЛОВ

Trunk pipeline transportation is the most important component of fuel and energy complex of Russia. In accordance with the regulations, control of equipment operation, compliance with labor protection and industrial safety requirements at production facilities as high-risk areas is carried out. Based on the results of monitoring the operation of road construction equipment, it was established that the majority of violations occur in the operation of video recording equipment. To optimize the process of managing video information, the authors have developed a software package (PC) using artificial intelligence methods for digital processing of video content, which allows analyzing data received from video recorders. The software product is designed to automate the process of processing video data: identifying violations in the operation of video recording; operational control and analysis of performance indicators of the DVR; creating a database with identified violations; generating operational, reliable information online from construction equipment. The developed computer program examines video analytics scenarios that make it possible to automate the processing of video materials: defocus or contamination of the video camera lens (cloudy, unclear image, dirty or obscured camera lens); disconnecting the video camera from the DVR (recording is in progress, a black or blue screen is recorded with time stamps on the video); lack of movement (recording of “garbage” video without production of work, no movement, picture does not change); interference when recording video (stripes, strong video jerking, video “scattering” into rectangular segments). The software package consists of 3 main modules, each of which has its own functionality for a comprehensive solution to the task. The use of a software package allows you to identify violations in the operation of video surveillance equipment. Automated analysis of video information is considered as a resource for increasing the efficiency of management and safe operation of special equipment. Using video analysis systems, you can obtain valuable information about the quality of work of company personnel at remote sites, which allows for a more adequate assessment of their work, as well as checking compliance with safety standards at high-risk sites. Implementation of computer vision-based solutions in the business processes of oil companies will allow to achieve higher productivity, profitability and competitiveness of the economic sector.

Measuring visual acuity and spherical refraction with smartphone screens emitting blue light

IntroductionA periodical self-monitoring of spherical refraction using smartphones may potentially allow a quicker intervention by eye care professionals to reduce myopia progression. Unfortunately, at low levels of myopia, the far point (FP) can be located far away from the eye which can make interactions with the device difficult. To partially remedy this issue, a novel method is proposed and tested wherein the longitudinal chromatic aberration (LCA) of blue light is leveraged to optically bring the FP closer to the eye. MethodsFirstly, LCA was obtained by measuring spherical refraction subjectively using blue pixels in stimuli shown on organic light-emitting diode (OLED) screens and also grey stimuli with matching luminance. Secondly, the visual acuity (VA) measured with a smartphone located at 1.0 m and 1.5 m and displaying blue optotypes was compared with that obtained clinically standard measurements. Finally, the spherical over refraction obtained in blue light with a smartphone was compared with clinical over-refraction with black and white (B&W) optotypes placed at 6 m. ResultsMean LCA of blue OLED smartphone screens was −0.67 ± 0.11 D. No significant differences (p > 0.05) were found between the VA measured with blue optotypes on a smartphone screen and an eye chart. Mean difference between spherical over-refraction measured subjectively by experienced subjects with smartphones and the one obtained clinically was 0.08 ± 0.34 D. ConclusionsSmartphones using blue light can be used as a tool to detect changes in visual acuity and spherical refraction and facilitate monitoring of myopia progression.

Design of Urban Public Landscape Lighting Control System Based on Dmx512 Protoco

Design an urban public landscape lighting control system based on DMX512 protocol to improve the lighting effect of urban public landscapes. The system uses the upper computer urban public landscape scene transformation software to edit the colour change data of urban public landscape lamps, set a reasonable number of sub-controllers according to the actual needs of urban public landscape scenes, and store relevant data in the SD card of the data storage layer. The Ethernet transmits the data in the SD card to the lighting control module, the main controller transmits the data in the SD card to the sub-controller, and the ARM of the sub-controller decodes the urban public landscape scene data, and uses the fireworks algorithm-fuzzy adaptive PID. The control algorithm solves the control data of urban public landscape lighting lamps, and the data that meets the DMX512 protocol is edited by FPGA and transmitted to the DMX512 controller. Through the DMX512 controller, the control data of urban public landscape lighting lamps is transmitted to the equipment module realize the control of LED lamps for urban public landscape lighting. The experimental results show that the response speed of the system is fast, at 0.60s it can quickly reach the illuminance value of the park landscape lighting LED light 7.5 lx set in the experiment, and its control ability is strong. At the same time, the system has high software and hardware compatibility and system stability. Better, in multiple operating systems, there will be no problems such as flashback, blue screen, crash, etc., ensuring the safe operation of the PC and improving the effect of park landscape lighting control.

This study aims to explore the impact of LED screen virtual production studios on the contemporary film and television industry, content production, and visual aesthetics. The study employed literature analysis and in-depth interviews as research methodologies. Findings indicate that, firstly, the adoption of LED screen virtual production studios requires the post-production process to be initiated during the pre-production stage, and the preview of virtual and real scenery must be completed before shooting, resulting in a change in the production process. Secondly, LED screen virtual production studios are currently primarily used for producing advertisements and music videos. The study suggests that, in the future, the studio can be employed for creating films or television series in order to expand the range of content production and increase international competitiveness. Finally, the deep integration of various digital technologies in visual aesthetics allows performers to perceive the realism of their surroundings while performing in the virtual space, thereby creating a realistic virtual image to immerse viewers in an aesthetically pleasing experience of perceptual realism.</p> <p> </p>

Enhanced Lip-Contour During Facial Scan for 3D DSD and Implant Planning: A Blue Screen Approach.

When obtaining 3-dimensional (3D) facial images for digital smile design (DSD) and dental implant planning, inaccuracies may frequently be introduced by distortion in the region between the lips' vermilion border and the teeth. The present clinical technique aimed to reduce such deformation during face scanning, thereby facilitating 3D DSD. This is also essential to plan bone reduction with precision for implant reconstructions. A custom-made silicone matrix acting as a blue screen provided reliable support for 3D visualization of facial images in a patient requiring a new maxillary screw-retained implant-supported fixed complete denture. Imperceptible volumetric changes were registered in the facial tissues when the silicone matrix was added. The usual deformation of the lip vermilion border originating in face scans was overcome by applying blue-screen technology with a silicone matrix. Reproducing the vermilion border of the lip contour accurately may offer improved communication and visualization for 3D DSD. The silicone matrix was a practical approach that acted as a blue screen to display the transition from lips to teeth with satisfactory precision. Implementing blue-screen technology in reconstructive dentistry might increase predictability by reducing errors when scanning objects with challenging-to-capture surfaces.

Assessment of the Effect of Blue Light on Visual Acuity among College Students

Visual acuity is the acuteness or clarity of vision which is dependent on the shortness of the retinal focus within the eye, and the sensitivity of the interpretative faculty of the brain. It is expressed as a fraction, such as 20/20 or 6/6 which is the normal visual acuity. Poor or impaired visual acuity is expressed as 20/40 and below or 6/9 and below. Blue light, which is one of the visible rays from the sun and also an artificial constituent of many modern devices, is a source of illumination which among other factors strongly affects our visual acuity. The present rapid, steady advancement in technology has led to a great increase in our usage and exposure to blue light. It is not uncommon nowadays to easily find someone who spends his entire day on digital screen, and many times even a great deal of the nighttime is also spent on blue-light-emitting technologies. The aim of this study is to assess and determine how this blue light affects college students and perhaps their productivity. A descriptive cross-sectional study was conducted using the focus group discussion (FGD) technique amongst 100 college students across five departments in College of Health Sciences, Nnamdi Azikiwe University, Nnewi Campus. The mean age of the respondents was 22.06 years. More of the respondents were females (66%) while 34% were males. The prevalence of visual acuity impairment after a considerably long usage of blue light was 37%. The majority of the respondents (87%) use a light-emitting diode (LED) technology torch/lantern during their night studies. 82% also uses their mobile phones for their studies and other academic works in which they have to spend many hours at once on the screen. Many others are exposed to other sources of blue light, and more even combine usage of different sources of blue light at once. The prevalence of visual acuity status below 6/6 amongst the students was high, and this is worrisome with regards to its long term effects or cumulative effects on their vision. Adequate sensitization on the harmful effects of long exposure to blue lights, usage of blue light filters/glasses (photochromic lens, for instance), taking frequent breaks from digital screens, encouraging outdoor use of blue light screens, early and proper management of impaired vision and more intakes of foods that enhance eyesight are recommended.

Background removal of video in realtime

Background removal for video is a computer-vision based system to remove the background from a video with ease. Creating a professional background when at home, i.e., not in a very professional environment, can be a tedious task. Not everyone has time to learn editing and the technicalities involved in having an entire setup for creating a sophisticated background and it is not practical that normal people buy green screens or blue screens just for their everyday formal meets. Our goal is to create a quick and easy solution to that by removing background in real time while also maintaining the quality of the call, having the additional benefit of adding custom backgrounds and enabling users to add effects like adjust lighting, contrast etc., we are combining all 4-5 steps in 1 single step. SelfieSegmentation module of Mediapipe helps us achieve this. The Selfie Segmentation API creates an output mask from an input image. The mask will be the same size as the input image by default. A float integer with a range of [0.0, 1.0] is assigned to each pixel of the mask. The higher the confidence that the pixel depicts a person, and vice versa, the closer the number is to 1.0.

Radio Pictures, Blank Transmissions

Abstract A key aspect of avant-garde practice is the critique of the relation between medium and genre. Following Cage’s chance-procedural experiments, Nam June Paik and Wolf Vostell explored a radical repurposing of medium as technology, transforming TV and radio from sites of broadcast performance to sources of indeterminate electronic sound and image. This in turn fed into a reconception of the verbo-visuo dichotomy as text-effect, or cinemato/graphy, and a parallel conceptualisation of text as sites of transmission. While new media tends towards instantaneous full-immersion virtual reality, mimetic technologies remain haunted by what does not transmit—between sound/image, speech/writing, and in the work of erasure, silence, blankness and noise (all of which acquire the status of aesthetic information). In this relation I propose to examine a piece nominally cast as “cinema”: Derek Jarman’s Blue (1993), a 79-minute poetic meditation in the voices of Jarman, John Quentin, Nigel Terry and Tilda Swinton over a monochrome blue screen (inspired by Yves Klein’s Symphonie Monotone and the tonal quality of IKB). The production of Blue, in the form ostensibly of both a “transmission error” and a “radio picture,” speaks to the idea of invisible cinema. In doing so, Blue harks back to Guy Debord’s anti-cinematic pronouncement ‘there’s no more cinema, cinema’s dead’: a blank cinema broadcasting from beyond the grave.

Determining the Best Management Strategy for Preventing Short-Term Effects of Digital Display Use on Dry Eyes.

To assess and compare the effectiveness of four main management strategies for preventing short-term effects of digital display use on dry eye signs and symptoms. The ocular surface, tear film, and visual fatigue of 47 healthy individuals were assessed before and after reading on a laptop computer for 20 min under five different experimental conditions: control, instillation of artificial tears, taking a brief break, using a blue light screen filter, and blink control. Measurements included the Ocular Surface Disease Index (OSDI) Questionnaire, 5-item Dry Eye Questionnaire (DEQ-5), tear meniscus height (TMH), noninvasive keratograph break-up time (NIKBUT), bulbar conjunctival redness, and pupil size. Worse results were obtained after the control and blue light filter conditions in all variables (P≤0.037). A higher post-task DEQ-5 score (P=0.013) and TMH (P<0.0005) were obtained when taking a brief break compared with pretask, although the increase in symptoms was significantly smaller than that observed in the nonmanagement control condition (P≤0.036). Similarly, a smaller increase in OSDI and DEQ-5 was obtained with the use of artificial tears and blink control in comparison with the control condition (P≤0.008), whereas a greater increase in DEQ-5 and decrease in NIKBUT was obtained for the blue light filter condition in comparison with the instillation of artificial tears (P=0.017) or blink control (P=0.008), respectively. Finally, a significantly lower post-task pupil size was obtained for all the conditions (P≤0.027). The instillation of artificial tears and blink control were the best management strategies for preventing short-term effects of digital display use on dry eyes. Conversely, using a blue light filter did not offer any benefits.

Machine Learning Models for Predicting Breast Cancer Risk in Women Exposed to Blue Light from Digital Screens.

Nowadays, there is a growing global concern over rapidly increasing screen time (smartphones, tablets, and computers). An accumulating body of evidence indicates that prolonged exposure to short-wavelength visible light (blue component) emitted from digital screens may cause cancer. The application of machine learning (ML) methods has significantly improved the accuracy of predictions in fields such as cancer susceptibility, recurrence, and survival. To develop an ML model for predicting the risk of breast cancer in women via several parameters related to exposure to ionizing and non-ionizing radiation. In this analytical study, three ML models Random Forest (RF), Support Vector Machine (SVM), and Multi-Layer Perceptron Neural Network (MLPNN) were used to analyze data collected from 603 cases, including 309 breast cancer cases and 294 gender and age-matched controls. Standard face-to-face interviews were performed using a standard questionnaire for data collection. The examined models RF, SVM, and MLPNN performed well for correctly classifying cases with breast cancer and the healthy ones (mean sensitivity> 97.2%, mean specificity >96.4%, and average accuracy >97.1%). Machine learning models can be used to effectively predict the risk of breast cancer via the history of exposure to ionizing and non-ionizing radiation (including blue light and screen time issues) parameters. The performance of the developed methods is encouraging; nevertheless, further investigation is required to confirm that machine learning techniques can diagnose breast cancer with relatively high accuracies automatically.

Blan/ck Screens: Chroma Screens Performing Race

Chroma screens is a term for the green and blue screens used in filmmaking, television, and graphics during image making for the compositing of other images in post-production. Engaging an agential realist framework to deliberate on this mode of screens wherein they are without images, I consider chroma screens in and through material-discursive practices to argue that the green and blue colors of chroma screens can be considered a cultural enactment of racialized media practices. I take the image blankness of chroma screens as the condition for a performance of blackness/race. An analysis of Sondra Perry’s work, Graft and Ash for a Three-Monitor Workstation (2016), opens onto how racial practices and concepts around blackness have functioned in the very blankness of chroma screens. The blan/ckness relationship in Perry’s work is leveraged to become generative of a differencing, a performance that not only sustains blackness, a difference in color, but recognizes and animates it in constructive ways. In this paper I show that neither blackness nor whiteness are pre-given but are caught up with a powerful imaging and medial technique, co-constituted in, with, and through chroma screens.

Blue Screen of Death? Obsolescence and Structural Change in the Computer Age

Mars Blue Clearing and Allais Effect

Starting from the so-called “blue clearing” phenomenon, this paper establishes a link between disturbances of the Martian gravitational potential, the Allais effect of syzygy, astral influences and the Raman Stokes effect. This phenomenon is apparently peculiar to the Martian atmosphere. Photographs of Mars taken in blue light normally show only the atmosphere itself and clouds high above the surface. On occasion of oppositions, however, blue photographs will penetrate in varying degrees to the surface of Mars. Curiously, a burst of brightness and storms then occur on Mars. The atmosphere and clouds can be seen and photographed at short wavelengths by Earth-based telescopes equipped with a Wratten 47 filter. It happens that the blue screen of the filter suddenly begins to disappear and that the Martian surface becomes visible. The exact mechanism that produces blue clearing when Earth is between the Sun and Mars is highly speculative. We believe that the “Allais syzygy effect” may explain this phenomenon. The opposition would generate a “gravito-electromagnetic tension”, which would spawn fluctuations in the gravitational potential of Mars, accompanied and linked to an electromagnetic effect. The outcome would be to trigger dust storms and exacerbate a disorderly excitement of molecules in the atmosphere. The thermal agitation facilitates the absorption of energy and the formation of small condensations that cause light scattering. Assuming that the Martian gravity decreased slightly, a Stokes Raman scattering would manifest at intramolecular level of the Martian atmosphere: the emitted photon has a lower energy than the absorbed photon. Therefore, it is mainly the waves corresponding to the spectral regions yellow, orange or red that are diffused, what eliminates short wavelengths. We deduce that the size of the inhomogeneities resulting from thermal excitation turns out to be greater than the length of the light waves of blue or purple regions of the spectrum.

The Influence of Virtual Secure Mode (VSM) on Memory Acquisition

Recently, acquiring the Random Access Memory (RAM) full memory and access data is gaining significant interest in digital forensics. However, a security feature on the Windows operating system - Virtual Secure Mode (VSM) - presents challenges to the acquisition process by causing a system crash known as a Blue Screen of Death (BSoD). The crash is likely to occur when memory acquisition tools are being used. Subsequently, it disrupts the goal of memory acquisition since the system must be restarted, and the RAM content is no longer available. This study analyzes the implications of VSM on memory acquisition tools as well as examines to what extent its impact on the acquisition process. Two memory acquisition tools, namely FTK Imager and Belkasoft RAM Capturer, were used to conduct the acquisition process. Static and dynamic code analyses were performed by using reverse engineering techniques that are disassembler and debugger. The results were compared based on the percentage of unreadable memory between active and inactive VSM. Static analysis showed that there is no difference between all applications’ functions for both active and inactive VSM. Further Bugcheck analysis of the MEMORY.DMP is pointed to the ad_driver.sys module in FTK Imager that causes the system to crash. The percentage of unreadable memory while running on active VSM and inactive VSM for Belkasoft is about 0.6% and 0.0021%, respectively. These results are significant as a reference to digital investigators as consistent with the importance of RAM dump in live forensics.

Low-Dimensional CsPbBr3@CoBr2 Super-Nanowire Structure for Perovskite/PMMA Composite with Highly Blue Emissive Performance

In this study, low-dimensional CsPbBr3@CoBr2 super-nanowire (SNW) structures were synthesized via a one-pot heating strategy for highly blue emissions. By introducing CoBr2 to CsPbBr3 precursors, the shape of perovskite nanocrystals was changed from cuboids to a super-nanowire structure, as revealed through a transmission electron microscope. SNWs were formed from stacked segments of nano-plates (lateral dimension of 10–12 nm and thickness of ~2.5 nm) with lengths of several microns. The fabricated sample absorbs light at a wavelength of &lt;450 nm, and it is emitted at a wavelength of 475 nm. It also has a radiant flux conversion efficiency of up to 85% when stimulated by a 430 nm LED light source. The average decay time of up to 80 µs indicates that they effectively prevent the recombination of electron–hole pair. The optical performance still remains over 65% when the ambient temperature is up to 120 °C compared with that under room temperature. The excellent color purity, optical quantum efficiency, long carrier lifetime, and thermal stability make CsPbBr3@CoBr2 SNWs highly promising for a range of photolumicescence applications, such as a high color rendering index lighting and transparent blue emissive screen.
