Methods for Adaptive Transformation of Content in Hypertext Format on Corporate TV and Information Kiosks of Educational Institutions

Purpose of the study: to consider and implement in practice a system for displaying content on screens of different resolutions and orientations in relation to an educational institution, using both a pure Smart TV (built-in browser of modern TV) and a player connected to Digital Signage screens. In system engineering, the main emphasis (and, as a result, the key task) is on the absence of duplication of content for different types of output screens (including interactive touchscreen kiosks), which is especially important because the implemented system will be built on free, open-source technologies and integrated into the current university website, which no other proprietary Digital Signage software system can offer.Materials and methods: the study uses different methods of transformation and output of content, but adaptation methods based on cascading style sheets (CSS) are mainly used. The experience of foreign programmers working with adaptive layouts for the web and operating their own blogs was studied (in the “Reference” section). Compromise methods for displaying graphic images and video materials are considered and proposed based on the experience gained during testing of the prototype system.Results: development of a system for displaying content on multi-format screens, requiring minimal subsequent support and intervention from the administrator responsible for filling it with content. An analysis of some potential solutions and their compatibility was carried out, taking into account browser support for CSS3 and HTML5 standards, and working solutions were selected that can be used in the design of individual templates for displaying content in hypertext format and CSS designs (rules) that work for the purpose of the study. The article compares approaches to designing adaptive templates for displaying web content in HTML (hypertext) format. The basic principles are considered under which content intended primarily for a university website can, without a third-party administrator (and also, in some cases, with minimal intervention) be displayed on corporate TV and touchscreen kiosks of universities thanks to the use of cascading style sheets (CSS) and relative units of measurement (vh, vw, vmin, vmax) and tags introduced in HTML5. The article also discusses how to level out the nuances associated with different resolutions of graphic images and screen orientation.Conclusion: the final paragraphs of the article conclude on the nuances of the functioning of the developed system, the effectiveness of which directly depends on methods of implementation and technologies used, chosen and discussed in the article. The implementation of the system will increase the awareness of students of an educational institution about events (announced or conducted), and will allow the system administrator to increase work efficiency by publishing and administering content only in “one window” (for example, on the university website), and the developed output template and/or CSS rules will display it on the internal screens, maintaining readability and perception of information. The developed and tested methods can be used by programmers, working in educational institutions.

R2Play development: Fostering user-driven technology that supports return-to-play decision-making following pediatric concussion.

To design a multi-domain return-to-play assessment system (R2Play) for youth athletes with concussion. The R2Play system was developed using an overarching user-centered approach, the Design Thinking Framework, and research activities included: 1) structured brainstorming within our research team, 2) interviews with clinician and youth sports coaches, 3) building a testable prototype, and 4) interface testing through cognitive walkthroughs with clinician partners. Clinician and coach participants provided feedback on the R2Play concept, which was integrated into the design process and provided future directions for research. Examples of feedback-driven design choices included reducing assessment time, increasing ecological validity by adding in background noise, and developing youth-friendly graphical results screens. Following refinement based on stakeholder feedback, the R2Play system was outlined in detail and a testable prototype was developed. It is made up of two parts: a clinician tablet, and a series of tablet "buttons" that display numbers and letters. Youth athletes run between the buttons to connect a "trail" in ascending alphanumeric order, 1-A-2-B, etc. Their performance across a series of levels of increasing difficulty is logged on the clinician tablet. Initial testing with five clinicians showed the system's interface to have excellent usability with a score of 81% (SD = 8.02) on the System Usability Scale. Through this research, a prototype of the R2Play system was innovated and evaluated by clinician and coach stakeholders. Initial usability was excellent and directions for future iterations were highlighted. Outcomes suggest the potential benefits of using technologies to assist in complex clinical assessment, as well as utilizing a user-centered approach to design.

Design module for speech recognition graphical user interface browser to supports the web speech applications

The web speech API has made it possible to integrate audio data into web applications and make it a unique experience for all customers and users of modern applications. The website can only be accessed through devices equipped with a which stands for graphical user interface (GUI) and screen. For this to be done, there must be a physical attraction with such devices. This paper presents speech recognition using a web browser (SRWB) which permits browsing or surfing the internet with the use of a standard voice-only and vocal user interface (VUL) development. The SRWB system input from the users in form of vocal commands and covers these voice commands to HTTP requests. The SRWB system will send the voice commands to the web server for processing purposes and when the processing is done, the converted or translated HTTP response is outputted to the end-users in a voice format made audible with the attached loudspeakers. SAPI, developed by Microsoft, allows the use of SRWB in Windows applications. The algorithm is implemented by the system to achieve its goal for web content, classifying, analyzing, and sending important parts of web pages back to the end-user.

Superimposed, Still

Superimposed, Still Kris Cohen (bio) A man in a white shirt and dark tie, microphone pressed to his upper lip, addresses a viewer, us, with his voice. But his eyes are focused on another task (Figure 1). Superimposed on his face is the text that, somehow, we know to be the focus of his work: "statement one: word word word …," with "word" repeated another ten times followed by an ellipsis. The image I'm describing is a still, an extract. This particular still superimposes two video feeds that are themselves intricately mediated: the first image results from pointing a video camera, at very close range, at a small circular calligraphic monitor that hosts the text ("word word word …"); the second results from angling another camera, also at very close range, up at the face of the computer user as he himself stares into a terminal networked to a time-sharing computer. On that terminal, the user, the man in a tie, sees the same text that we see superimposed on his face. The effect is strange, estranging. It is also an invitation. Such a still doesn't freeze or extract; it agitates the proceedings. What it agitates in these two particular video feeds is their aspiration to establish a space for living, dwelling, working that was to be a training in a style of personhood. Computational personhood is one kind of shorthand for the style I want to describe. But whiteness is another, a racial whiteness constituted less as an identity and more as a possibility, an aptitude, an attitude made possible in and as the graphical screen that Douglas Engelbart here demonstrates. Superimposition names the video technique that made the demonstration both illustrative and a marvel. But it will also turn out to be a better name for the infrastructure provided to whiteness by the graphical screen being demonstrated, one that no longer relies on a politics of representation so much as a graphics of superimposition. [End Page 163] Click for larger view View full resolution Figure 1. Still image, from Douglas Engelbart's demonstration of the oN-Line System (NLS) at the 1968 Fall Joint Computer Conference, San Francisco, CA, December 9–11, 1968. That some readers will already know too much about the event that I'm describing while some will have no idea what I'm referring to is itself telling of the particular kind of oblivion into which Engelbart's demonstration of an early graphic computer interface has fallen: both too historicized and not enough. The effect of the superimposition is therefore a strange amalgam. The temptation will be to see it as an allegory, the user superimposed into the new graphicalized field of a computer terminal—an allegory of capture, say, or conscription. But the effect is actually more literal than allegorical. The story I want to sketch briefly, with the still as historical agitator, has to do with how this graphical space generates the racial constitution of the personal computer user. The still is from the demonstration that Engelbart and his team performed for an audience in 1968.1 As described on the website of the [End Page 164] Defense Advanced Research Projects Agency (DARPA), a funder of Engelbart's work, "Engelbart's terminal was linked to a large-format video projection system loaned by the NASA Ames Research Center and via telephone lines to a [Scientific Data Systems] 940 computer (designed specifically for time-sharing among multiple users) 30 miles away in Menlo Park, California, at the Augmentation Research Center, which Engelbart founded at SRI [the Stanford Research Institute]. On a 22-foot-high screen with video insets, the audience could see Engelbart manipulate the mouse and watch as members of his team in Menlo Park joined in the presentation."2 White button-up shirt, dark tie, the insinuation that a sports jacket has recently been removed—this human figure is superimposed on or into the field of the computer screen (whether on or into, it is in the nature of the graphical screen to render all prepositions inadequate). That field is in some ways most remarkable for its blankness, the fact that there is almost nothing in it, including...

Inexpensive multispectral imaging device

Multi/hyperspectral imaging is an important technique to obtain color data and spectral monitoring. It is a precise remote sensing technique that includes two or more bands in the visible and invisible spectrum. This study demonstrates the design and construction of a low-cost, multispectral imaging system using a single linear array sensor and a varifocal lens coupled to individual spectral band-pass filters. The system allows the automated data acquisition of raw spectral data for seven spectral bands, each with different wavelengths. The raw data are visualized in real-time to generate images of spectral bands to obtain the desired spectral information on the computer graphical screen. Sensor arrays with spectral responsivity between 0.3 and 1.05 μm and motorized filter disks with a linear guide are used for acquiring data from specific wavelengths. Axis movement of the imaging device is achieved by a linear guide for spatial monitoring. Seven different bands are scanned and transferred to the computer via motorized band-pass filter sets with the imaging device. The multispectral imaging device has high accuracy with a 0.9936 linear correlation coefficient (r2) and averaged noise of the total system is below 1% (0.7%). Although the present configuration uses seven spectral bands including visible and narrow bandpass optical filters to obtain multispectral information from an object, the system is designed to have a replaceable and selectable motorized rotating filter, easily remounted, and adjusted up to forty spectral bands with 20 nm full width at half maximum (FWHM).

Image Analysis to Optimize Calculations of Grinding Modes

Modeling helps to investigate and analyze the interrelationships of grinding parameters as a single system. The article describes a computer model of the surface layer of a grinding wheel, taking into account the cutting modes and characteristics of the circle. The subsystem of the surface layer of the grinding wheel is the most important subsystem of grinding, since it connects the main characteristics of the circle with the cutting modes and with the parameters of the workpiece. The output characteristics of the model are the parameters of the working layer with a height of several micrometers, in which micro-cutting occurs. It is impossible (or very difficult) to obtain them by conducting full-scale experiments, since the processes are instantaneous, and the cutting elements have micro-dimensions. This problem was solved by creating a simulation stochastic model based on the geometric representation of the surface layer, which clearly displays the result. The analysis of the image of this model allowed us to numerically describe the output parameters of cutting.The article offers a faster algorithm for analyzing the image of the simulation model of the surface layer. It is carried out over a matrix containing numerical information about the projection of the surface layer, the main parameters of each single slice are calculated, and only after that the result is displayed on the graphic screen. To simulate a single grinding mode, it is necessary to repeat the process of "image creation - image analysis– output of results" hundreds of times until a stable state is reached.The use of the algorithm in an automated system will allow you to create a system for automatically searching for optimal grinding modes, as well as to derive analytical dependencies of cutting modes on input parameters, for example, on the parameters of the circle and the workpiece.

Articulation of Facade Graphics and Techniques of its Implementation

The article deals with issues at the boundary of architecture and technology, related to visual articulation. The facade graphics is a relatively new phenomenon that has arisen over the last two decades. Some of the image implementation techniques it uses have been known for a long time. Some of them are derived from stained glass (e.g. the technique of manual enamel application), some are related to the already known techniques of workshop graphics (screen printing). One of the latest technological achievements is the development of digital printing technology. Each of the aforementioned techniques has specific artistic possibilities and means of expression, which influences the articulation of the image in the external partition and has a significant impact on a number of compositional aspects. The image placed in the façade supports the building's form, underlining its shape, emphasizing important places in the building. The work examines the relationship between the applied techniques of implementation and the properties of the image on glass. An important part is to determine to what extent the construction of the image and the applied plastic measures affect the visual range of the glass partition and the functional properties. Particularly interesting projects are those made with several techniques, and those in which a new technique was discovered, which is later copied in other projects. The research can make a strong case for using artistic glass in the facade of a building and provide guidance for designers and investors. The publication will present examples of implementations placed in the facade of the building. The phenomenon will be investigated on the basis of buildings constructed over the last two decades. Due to the global nature of plastic phenomena, there is no limited research territory.

Fault Classification System for Switchgear CBM from an Ultrasound Analysis Technique Using Extreme Learning Machine

Currently, the existing condition-based maintenance (CBM) diagnostic test practices for ultrasound require the tester to interpret test results manually. Different testers may give different opinions or interpretations of the detected ultrasound. It leads to wrong interpretation due to depending on tester experience. Furthermore, there is no commercially available product to standardize the interpretation of the ultrasound data. Therefore, the objective is the correct interpretation of an ultrasound, which is one of the CBM methods for medium switchgears, by using an artificial neural network (ANN), to give more accurate results when assessing their condition. Information and test results from various switchgears were gathered in order to develop the classification and severity of the corona, surface discharge, and arcing inside of the switchgear. The ultrasound data were segregated based on their defects found during maintenance. In total, 314 cases of normal, 160 cases of the corona, 149 cases of tracking, and 203 cases of arcing were collected. Noise from ultrasound data was removed before uploading it as a training process to the ANN engine, which used the extreme learning machine (ELM) model. The developed AI-based switchgear faults classification system was designed and incorporated with the feature of scalability and can be tested and replicated for other switchgear conditions. A customized graphical user interface (GUI), Ultrasound Analyzer System (UAS), was also developed, to enable users to obtain the switchgear condition or classification output via a graphical interface screen. Hence, accurate decision-making based on this analysis can be made to prioritize the urgency for the remedial works.

The kitchen is going to be one of the interfaces which will be provided in accordance with the following priority (first-come-first-served). This app will help you to find more detailed information on the restaurant and its services, as well as the ease of ordering food and reservation table.

Latency and Cybersickness: Impact, Causes, and Measures. A Review

Latency is a key characteristic inherent to any computer system. Motion-to-Photon (MTP) latency describes the time between the movement of a tracked object and its corresponding movement rendered and depicted by computer-generated images on a graphical output screen. High MTP latency can cause a loss of performance in interactive graphics applications and, even worse, can provoke cybersickness in Virtual Reality (VR) applications. Here, cybersickness can degrade VR experiences or may render the experiences completely unusable. It can confound research findings of an otherwise sound experiment. Latency as a contributing factor to cybersickness needs to be properly understood. Its effects need to be analyzed, its sources need to be identified, good measurement methods need to be developed, and proper counter measures need to be developed in order to reduce potentially harmful impacts of latency on the usability and safety of VR systems. Research shows that latency can exhibit intricate timing patterns with various spiking and periodic behavior. These timing behaviors may vary, yet most are found to provoke cybersickness. Overall, latency can differ drastically between different systems interfering with generalization of measurement results. This review article describes the causes and effects of latency with regard to cybersickness. We report on different existing approaches to measure and report latency. Hence, the article provides readers with the knowledge to understand and report latency for their own applications, evaluations, and experiments. It should also help to measure, identify, and finally control and counteract latency and hence gain confidence into the soundness of empirical data collected by VR exposures. Low latency increases the usability and safety of VR systems.

The design and development of an automatic transmission solenoid tester for wheeled vehicles

Solenoids are the most critical components in automatic transmissions. They are used to control the shift points, clutch locking, or pressure regulation of automatic transmissions. Since the number, type, and order of the solenoids all differ when they are used in different vendor’s automatic transmissions, making accurate normal/abnormal decisions for solenoids is very difficult, as it can lower the maintenance quality, to waste labor and material cost, and even reduce driving safety. This article proposes an “abnormal” inspecting method (i.e. for abnormality) for solenoids with high inspect ability and develops a learnable automatic transmission solenoid tester. This tester can perform solenoid testing on multiple channels at the same time. The test result statistics for all channel solenoids tested are generated automatically. It also provides visibility for users to view the difference comparisons of testing curves of temperature, pressure, voltage, current, and resistance on a graphical screen. The curve visibility function will be helpful for the solenoid diagnosis of abnormal or fault reasons.

Compact Square-Wave Pulse Electroporator with Controlled Electroporation Efficiency and Cell Viability

The design and development of a compact square-wave pulse generator for the electroporation of biological cells is presented. This electroporator can generate square-wave pulses with durations from 3 μs up to 10 ms, voltage amplitudes up to 3500 V, and currents up to 250 A. The quantity of the accumulated energy is optimized by means of a variable capacitor bank. The pulse forming unit design uses a crowbar circuit, which gives better control of the pulse form and its duration, independent of the load impedance. In such cases, the square-wave pulse form ensures better control of electroporation efficiency by choosing parameters determined in advance. The device has an integrated graphic LCD screen and measurement modules for the visualization of the current pulse, allowing for express control of the electroporation quality and does not require an external oscilloscope for current pulse recording. This electroporator was tested on suspensions of Saccharomyces cerevisiae yeast cells, during which, it was demonstrated that the application of such square-wave pulses ensured better control of the electroporation efficiency and cell viability after treatment using the pulsed electric field (PEF).

Hand-Held Magnetic Field Meter Based on Colossal Magnetoresistance-B-Scalar Sensor

This paper describes a newly developed hand-held magnetic field meter, which enables the measurement of the magnitude of pulsed, alternating, or permanent magnetic flux density in a range from 0.06 up to 10 T. The device measures the magnitude of magnetic flux density independent of the field direction (B-scalar) and its measurement frequency ranges from dc to 100 kHz. This magnetometer consists of a hand-held magnetic field measurement meter and a pluggable probe whose main element is a spintronic sensor based on the colossal magnetoresistance (CMR) phenomenon. The new design of a probe containing a temperature sensor and a CMR-B-scalar sensor made from two manganite films with different resistivity versus temperature dependences ensures a reduced response signal dependence on temperature and thus increased the accuracy of the measurements. The hand-held meter has a graphical color touch screen for the display of the waveforms and provides measurements without the use of external oscilloscopes or other analog graphing devices. This magnetometer can be used for various industrial and scientific applications such as for the investigation of high-power electrical motors, fast high electrical current transients appearing in cases of the commutation of pulsed power circuits, for the measurement of pulsed magnetic fields in magnetic coils, or for measuring the dynamics of magnetic fields during electromagnetic metal forming and welding.

Identification of potential Zika virus NS2B-NS3 protease inhibitors via docking, molecular dynamics and consensus scoring-based virtual screening.

The Zika virus has recently become a subject of acute interest after the discovery of the link between viral infection and microcephaly in infants. Though a number of treatments are under active investigation, there are currently no approved treatments for the disease. To address this critical need, we screened more than 7million compounds targeting the NS2B-NS3 protease in an attempt to identify promising inhibitor candidates. Starting with commercially and freely available compounds, we identified six hits utilizing an exhaustive consensus screening protocol, followed by molecular dynamics simulation and binding energy estimation using MM/GBSA and MM/PBSA methods. These compounds feature a variety of cores and functionalities, and all are predicted to have good pharmacokinetic profiles, making them promising candidates for screening assays. Graphical abstract Virtual screen of potential Zika virus NS2B-NS3 protease inhibitors.

Teaching HCI Skills in Higher Education through Game Design: A Study of Students’ Perceptions

Human-computer interaction (HCI) is an area with a wide range of concepts and knowledge. Therefore, a need to innovate in the teaching-learning processes to achieve an effective education arises. This article describes a proposal for teaching HCI through the development of projects that allow students to acquire higher education competencies through the design and evaluation of computer games. Finally, an empirical validation (questionnaires and case study) with 40 undergraduate students (studying their fifth semester of software engineering) was applied at the end of the semester. The results indicated that this teaching method provides the students with the HCI skills (psychology of everyday things, involving users, task-centered system design, models of human behavior, creativity and metaphors, and graphical screen design) and, more importantly, they have a positive perception on the efficacy of the use of videogame design in a higher education course.

A 3-LEVEL MULTIFACTOR AUTHENTICATION SCHEME FOR CLOUD COMPUTING

The objective of this paper is to propose a secure, user friendly and economical multi-level authentication scheme that uses multiple factors for gaining access to resource on insecure platforms and for financial transactions. The proposed study is based on a premise that when multiple levels and multiple factors are incorporated in an authentication scheme it not only becomes difficult to break but also resistant to different forms of attacks. This work purposes a scheme where authentication process is carried out in three levels using multiple factors and is called 3L-MFA. The scheme also uses Out of Band (OOB) authentication as one of the factors that offers credible security against man-in-the-middle (MIM) attack. The first level uses username password based on double encryption. Second level uses OTP verification based on Out of Band (OOB) authentication using email id and mobile number. Third level involves user’s interaction on graphical screen in terms of predetermined number of clicks on images, buttons and selection of predetermined number of menu items. The security of proposed system depends upon double encryption using SHA-1 and AES128-CBC, out of band authentication using OTP and user interaction on a graphical screen that uses probability combination of various numbers.
