Background Increasing the adoption of digital care tools, including video visits, is a long-term goal for the US Department of Veterans Affairs (VA). While previous work has highlighted patient-specific barriers to the use of video visits, few have examined how clinicians view such barriers and how they have overcome them during the rapid uptake of web-based care. Objective This study sought input from providers, given their role as critical participants in video visit implementation, to qualitatively describe successful strategies providers used to adapt their practices to a web-based care setting. Methods We conducted interviews with 28 VA providers (physicians and nurse practitioners) from 4 specialties that represent diverse clinical services: primary care (n=11), cardiology (n=7), palliative care (n=5), and spinal cord injury (n=5). All interviews were audio recorded and transcribed, and transcripts were reviewed and coded according to an iteratively created codebook. To identify themes, codes were grouped together into categories, and participant comments were reviewed for repetition and emphasis on specific points. Finally, themes were mapped to Expert Recommendations for Implementing Change (ERIC) strategies to identify evidence-based opportunities to support video visit uptake in the VA. Results Interviewees were mostly female (57%, 16/28), with an average age of 49 years and with 2-20 years of experience working in the VA across 16 unique VA facilities. Most providers (82%, 23/28) worked in urban facilities. Many interviewees (78%, 22/28) had some experience with video visits prior to the COVID-19 pandemic, though a majority (61%, 17/28) had conducted fewer than 50 video visits in the quarter prior to recruitment. We identified four primary themes related to how providers adapt their practices to a web-based care setting: (1) peer-based learning and support improved providers’ perceived value of and confidence in video visits, (2) providers developed new and refined existing communication and clinical skills to optimize video visits, (3) providers saw opportunities to revisit and refine team roles to optimize the value of video visits for their care teams, and (4) implementing and sustaining web-based care requires institutional and organizational support. We identified several ERIC implementation strategies to support the use of video visits across the individual-, clinic-, and system-levels that correspond to these themes: (1) individual-level strategies include the development of educational materials and conducting education meetings, (2) clinic-level strategies include identifying champions and revising workflows and professional roles, and (3) system-level strategies include altering incentive structures, preparing implementation blueprints, developing and implementing tools for quality monitoring, and involving executive leadership to encourage adoption. Conclusions This work highlights strategies to support video visits that align with established ERIC implementation constructs, which can be used by health care systems to improve video visit implementation.

We discuss the problem of the design of encoding profiles for web streaming. In this application, the video is normally embedded in a web page, and based on user preferences, e.g. browser stretch factor, full-screen mode, etc., the area that it occupies on the screen may be different. When multiple viewers tune to the same web page, this creates a distribution of possible player sizes. The key idea of this paper is to consider such distribution as input to the problem of the design of encoding profiles for web streaming. The objective is to maximize the average quality that can be experienced by a population of viewers. We define this problem mathematically, show that it belongs to a class of non-linear constrained optimization problems, and show how it can be solved practically. Examples of optimal profiles generated for different videos, networks, and player models are also provided. Provided results demonstrate the significance of accounting for player size distributions in the design of encoding profiles for web streaming.

Based on the analysis of the emotions and mentality of site B users watching videos, this paper proposes a method to visualize important attributes such as high-frequency words, the proportion of positive and negative comments, and word cloud diagrams. In the context of the rise of the Internet and the increasing application of Web 2.0, this paper took the Bilibili barrage text as the research object. Because of the large amount of barrage data, only individual barrages were selected as the analysis objects according to the requirements. The crawler was used to preprocess the crawled video barrage. Then machine translation knowledge and four algorithms such as the word segmentation algorithm and sentiment analysis algorithm were used to analyze the sentiment of the video barrage from three different dimensions and compare the results. Through the analysis of the visualization results, the differences in the emotional distribution of different video barrages were compared, and two important conclusions were drawn: First, the mentality of Bilibili users watching videos is positive; second, there is a certain correlation between the content of the video and the emotional orientation of the barrage, and mutual prediction can be made between the two. However, the research in this paper is only the tip of the iceberg in the research of public opinion analysis. At present, the application of sentiment analysis in public opinion still faces difficulties. How to optimize the algorithm model according to the current situation requires researchers to conduct deeper research and more extensive thinking.

"Developing Patient-Centered Inflammatory Bowel Disease–Related Educational Videos Optimized for Social Media: Qualitative Research Study." JMIR Medical Education 6, no. 2 (2020): e21639. http://dx.doi.org/10.2196/21639.
Texto completo da fonteResumo:
Background Important knowledge gaps have been identified related to the causes and symptoms of inflammatory bowel disease (IBD) and medical treatments and their side effects. Patients with IBD turn to social media to learn more about their disease. However, such information found on the web is misleading and often of low quality. Objective This study aims to gain an in-depth understanding of the unmet educational needs of patients with IBD and to use the resulting insights to develop a collection of freely available, evidence-based educational videos optimized for dissemination through social media. Methods We used design thinking, a human-centered approach, to guide our qualitative research methodology. We performed focus groups and interviews with a diverse sample of 29 patients with IBD. Data collection was performed in 3 phases (inspiration, ideation, and implementation) based on IDEO design thinking. Phase 1 offered insights into the needs of patients with IBD, whereas phases 2 and 3 involved ideation, prototyping, and video testing. A thematic analysis was performed to analyze the resulting data. Results Patients emphasized the need for educational videos that address their challenges, needs, and expectations. From the data analysis, 5 video topics and their content emerged: IBD treatments’ risks and benefits; how to be a self-advocate; how to stay healthy with IBD; how to cope with IBD; and educating families, friends, and colleagues about experiences of patients with IBD. Conclusions Design thinking offers a deep understanding and recognition of the unmet educational needs of patients with IBD; this approach informed the development of 5 evidence-based educational videos. Future research will formally test and disseminate these freely available videos through social media.

Texto completo da fonteResumo:
Background Neurofibromatosis (NF) is a rare genetic condition associated with lower but modifiable quality of life (QoL). Although a virtual live video program (Relaxation Response Resiliency Program for Neurofibromatosis [3RP-NF]; efficacy randomized controlled trial underway) that we created has been made available, ongoing barriers impede some patients from engaging in this intervention. A necessary next step is to develop a stand-alone web-based intervention that reduces barriers to accessing NF-specific psychosocial care. Objective First, we aim to develop a web-based platform (Neurofibromatosis-Web [NF-Web]) of our mind–body resiliency program (3RP-NF) through qualitative interviews with participants from an adult efficacy randomized controlled trial. Second, we aim to iteratively optimize the feasibility, acceptability, credibility, and satisfaction of the NF-Web platform through open pilot trials with participant exit interviews and explore quantitative outcomes within this sample. Here, we describe the protocol and study design, intervention, and analysis plan. Methods For aim 1, we will invite completers from our efficacy trial to participate in qualitative interviews. We will use data from these interviews to adapt the content of the live video program for asynchronous delivery and understand how to create a user-friendly format for an engaging web platform. For aim 2, we will enroll eligible participants recruited for the efficacy trial who could not enroll because of treatment barriers. Eligible participants will complete QoL, depression, anxiety, pain, treatment satisfaction, and program credibility measures at baseline and posttest. Inclusion criteria are identical to those for the efficacy trial, including stress and coping difficulties (self-report), no change in antidepressant medication in the past 3 months, no psychotherapy in the past 3 months, no major upcoming surgeries in the next 12 months, English speaking, ability to complete questionnaires on the web and participate in live video interventions, and consent before participation. The primary outcomes are feasibility, treatment satisfaction, and credibility. The secondary outcomes include physical, psychological, social, and environmental QoL; depression; anxiety; pain intensity; and pain interference. We will enroll at least two group cohorts and iteratively refine the program based on participant feedback after each cohort completes the open pilot trial. Results This trial is ongoing. We have completed the interviews (n=23) and analyzed the data to construct the website. Afterward, we will recruit our cohorts for the trial (approximately n=15/cohort; total=30). Recruitment will end by May 2021, with plans to analyze the data by October 2021. Conclusions We will develop the first web platform for people with NF with difficulties managing stress and NF symptoms and report on feasibility and preliminary effects in improving QoL and psychosocial functioning. NF-Web has potential to extend the reach of our 3RP-NF intervention by removing barriers to care, including lack of trained providers, scheduling difficulties, and appearance concerns.

The intensive use of social content anywhere and from any device presents new challenges for current systems and networks particularly when they are used by novice users. One of the most places where social channels are used by non-expert users and with a wide range of devices is at home. Unfortunately, current digital home systems lack of intelligent components that help terminals and users to find, configure and connect devices for using media content (video, audio, etc.) in an intuitive, transparent and optimized way. In this paper, the author discusses how the user's experience is negatively affected in existing digital home systems. Particularly, in heterogeneous environments with terminals and networks having different capabilities. The author discusses the home media access using a real-world evaluation of existing home systems. The author compares these evaluations to a Web-based approach and show how the use of the home network resources can be significantly improved for sharing and browsing media items and folders.

Journal, IJSREM. "Topic Modelling of Web Pages with Latent Dirichlet Allocation Methods." INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT 07, no. 11 (2023): 1–11. http://dx.doi.org/10.55041/ijsrem27350.
Texto completo da fonteResumo:
Topic modelling with Latent Dirichlet Allocation (LDA) is a popular technique used in natural language processing to uncover hidden thematic structures within a collection of documents. When applied to web pages, LDA can help in identifying prevalent topics or themes across these pages.. This study delves into the utilization of Latent Dirichlet Allocation (LDA) methods to extract underlying topics within web pages, a fundamental pursuit in understanding the multifaceted landscape of online information. Web content analysis presents unique challenges owing to its diverse nature—comprising text, images, videos, and structured HTML elements—mandating rigorous preprocessing strategies to homogenize the data. By adapting the LDA model to accommodate these challenges, this research tackles the task of uncovering latent thematic structures prevalent across web content. Methodologically, the study explores parameter tuning and model adaptation to optimize LDA for web page analysis, navigating complexities such as varied content formats, noise, and inherent biases in web data. Addressing these intricacies involves parsing HTML, extracting meaningful textual information, and refining tokenization processes. Evaluating the fidelity and interpretability of discovered topics becomes pivotal, prompting the utilization of coherence scores, perplexity metrics, and human assessment to gauge the quality of generated topics. Additionally, this research confronts the dynamic nature of web content, proposing strategies like continuous model retraining and dynamic topic modeling to accommodate evolving trends and updates. Practical applications of the extracted topics span a spectrum of domains, encompassing content recommendation systems, user behavior analysis, sentiment analysis, targeted advertising, and the enhancement of search algorithms for improved relevance and user engagement. Supported by illustrative case studies, this study elucidates how LDA serves as a potent mechanism to distill coherent and meaningful topics from web pages, offering invaluable insights into the hidden structures within the vast expanse of online information. St This comprehensive abstract encapsulates the depth and breadth of employing LDA for the analysis of web content, encompassing challenges, methodologies, evaluations, applications, and real-world implications.

Background Digital health interventions such as tailored websites are emerging as valuable tools to provide individualized exercise and behavioral change information for individuals diagnosed with cancer. Objective The aim of this study is to investigate and iteratively refine the acceptability and usability of a web-based exercise intervention (ExerciseGuide) for men with metastatic prostate cancer and determine how well individuals can replicate the video-based exercise prescription. Methods A laboratory-based multi-methods design was used, incorporating questionnaires, think-aloud tests, interviews, and movement screening among 11 men aged 63 to 82 years with metastatic prostate cancer. Overall, 9 participants were undergoing androgen deprivation therapy, and 2 were completing chemotherapy. Data were collected in two waves, with changes made for quality improvement after participant 5. Results The intervention’s usability score was deemed moderate overall but improved after modifications (from 60, SD 2.9 to 69.6, SD 2.2 out of 100). Overall, the participants found the intervention acceptable, with scores improving from wave 1 (24.2, SD 1.1 out of 30) to wave 2 (26.3, SD 2.1 out of 30). The personalized multimodal exercise prescription and computer-tailored education were seen as valuable. After wave 1, website navigation videos were added, medical terminology was simplified, and a telehealth component was included after expert real-time telehealth support was requested. Wave 2 changes included the added variety for aerobic exercise modes, reduced computer-tailoring question loads, and improved consistency of style and grammar. Finally, the participants could replicate the resistance exercise videos to a satisfactory level as judged by the movement screen; however, additional technique cueing within the videos is recommended to address safety concerns. Conclusions The acceptability and usability of ExerciseGuide were deemed satisfactory. Various problems were identified and resolved. Notably, the participants requested the inclusion of personalized expert support through telehealth. The resistance training algorithms were shown to provide appropriate content safely, and the users could replicate the exercise technique unaided to a satisfactory level. This study has optimized the ExerciseGuide intervention for further investigation in this population.

With the development of technology, the advent of e-books, computers, smartphones, and other electronic devices expanded the range of choices of media for reading, it also changed the way people consume information. Website, as a reading platform, has its advantages and disadvantages in reading experiences. For example, with a device connected to the internet, people can easily gain information and access what they want to read. Unlike traditional reading media such as books and newspapers, the website enables a variety of multimedia content, such as videos, animation, and images, which can make reading more engaging and informative, which further allows readers to enhance their understanding of a topic. However, as with any digital media, website reading may cause eye fatigue. And the movable images and inconsistent set type may be a disturbance. The diversity and potentiality of web reading call for advanced studies to further optimize the readers experience and eliminate the inferior strength of web reading. Compared with traditional printed media, this paper explores how website increases readers experiences in the field of sensory elements, interaction, and accessibility. The research methodology employed for this thesis involved reviewing academic literature and case studies. The results of the research indicate that websites indeed increase reading experiences for both people with and without disabilities. The findings suggest that websites provide readers with an attractive, delightful, and interactive experience. And the personalized settings, such as font size change, color adjustment, and alternative text, further increase the experience for people with different kinds of disabilities.

The demand for visual quality in video games is higher than ever. Video games approximate real objects via the tessellation of triangular polygons. Complex objects with a lot of detail require denser tessellations in order to be represented properly. However denser tessellations require more performance which can prevent the game from running properly in real time. Thus arises the problem of reducing the complexity of 3D objects in games while simultaneously preserving visual quality. An impostor technique approaches this problem by reducing the rendering cost. This project constructs a game engine and applies two existing impostor techniques: NP3D impostors and 2D impostors. A third impostor techniques is introduced where 3D objects are combined with 2D impostors and NP3D impostors. These techniques are then evaluated in terms of their effect on visual fidelity and performance. 2D impostors and NP3D impostors are revealed to be equally good at preserving visual fidelity but have different effects on performance. Using only 2D impostors is revealed to reduce CPU load. Using only NP3D impostors is revealed to reduce GPU load. The third technique is revealed to be completely ineffective.<br>Det ställs idag högre krav än någonsin på den visuella kvaliteten i tv-spel. Riktiga objekt approximeras i tv-spel med en tessellation av triangulära polygoner. Komplexa objekt med mycket detalj kräver en tätare tessellation för att kunna representeras korrekt. En tätare tessellation är däremot mer resurskrävande och detta kan hindra spelet från att köra ordentligt i realtid. Därmed uppstår problemet att reducera komplexiteten av objektet utan att försämra den visuella kvaliteten för mycket. Ett tillvägagångssätt är impostor-tekniker som minskar kostnaden av att rendera 3D objekt. Detta projekt konstruerar en spelmotor (en integrerad utvecklingsmiljö utvecklad för att skapa spel) och tillämpar två existerande impostor tekniker: NP3D impostors och 2D impostors. En tredje impostor-teknik introduceras även där 3D object kombineras med 2D impostors och NP3D impostors. Dessa tekniker evalueras därefter baserad på hur de påverkar visuell kvalitet och prestanda. 2D impostors och NP3D impostors visar sig vara lika bra på att bevara visuell kvalitet men påverkar prestandan olika. Att endast använda 2D impostors visar sig reducera CPU användning. Att endast använda NP3D impostors reducerar GPU användning. Den tredje tekniken visar sig vara fullständigt ineffektiv.

Texto completo da fonteResumo:
This qualitative study explored the quality of technology associated with interactive video (ITV) classes in distance education programs and the resulting satisfaction of the instructors teaching this format. The participants were full time instructors of a rural community college that used the ITV format. Community college ITV instructors are knowledgeable about the ITV technology and are in need of research that explores the satisfaction of that technology. Distance education theory, social constructivism, individual and collaborative learning, and technology formed the foundation for the research. Grounded theory was used to generate a theory about the perceptions of the instructors. Data collected included surveys, interviews, and observations of the interviews. Data were analyzed using theoretical sampling, constant comparison, open coding, axial coding, and selective coding. Analysis indicated that instructors' perceived greater satisfaction teaching in an ITV environment when the structure of the class was optimum for the course, the audio/visual technology worked effectively, the Web-enhanced component of the course ran smoothly, IT was available, quality training was offered, and transactional distance was perceived as minimal. This grounded theory provides positive social change for other educators and administrators who teach ITV by guiding their efforts to use ITV course delivery systems in ways that ensure the fulfillment of needs for both instructors and their students.

Texto completo da fonteResumo:
Snowboard media producers attempt to create subculturally relevant videos that connect with the audience. Videos provide the opportunity to report and document snowboarding activity, highlight new developments and provide visibility to prominent participants and associated businesses. Being a well-known and esteemed snowboarding participant is advantageous to being a producer, as it provides an identifiable cultural capital and implies a trustworthy ‘by-riders-for-riders’ philosophy. Connecting with the viewers is vital, as the audience plays a role in the distribution of videos by sharing and endorsing them through their social networks. Motivating factors in audience media sharing, also known as media spreading, include status seeking, improving credibility, personal satisfaction and personal expression.
Snowboarding was founded on anti-mainstream and anti-commercialism beliefs, which means that incorporating advertising and promotional messaging could negatively impact on audience connection. Yet, filming and producing snowboarding videos is difficult and expensive. Advertising represents an opportunity to attract funding and support to assist with production costs and, ultimately, provide profit. In order to accommodate advertising into their videos, producers are sometimes required to compromise their standards. This compromise represents a threat to audience connection. Producers believe that high quality, innovative snowboarding action footage provides the best opportunity to wow the audience. Various forms of advertising, including stealth marketing, sponsored journalism, and hybrid messaging, are often displayed in the moments between action footage shots, but advertising compromise can also affect action footage, particularly on client-funded projects. How advertising is incorporated can also depend on the industry the advertiser operates in. Alcohol brand advertising is identified as highly restrictive due to legal implications and public perceptions. Advertisers from businesses strongly related to the snowboarding subculture are more aware of their competitors’ presence in videos, which can cause conflict. Ski field support can be varied, despite high levels of visibility in the videos.

AbstractIIIF (International Image Interoperability Framework) is a collection of open web standards, broadly used for presenting and annotating high resolution images and audiovisual content, adopted by hundreds of GLAM (galleries, libraries, archives, museums) organisations worldwide, and permit the reuse and recombination of digital assets across traditional digital institutional boundaries. While these standards have been successful for 2D images and AV (Audio/Video) data, there is a growing interest in how they might be applied to 3D content. An example of this would be to combine shards of pottery from disparate collections into a single whole within a viewing experience. The IIIF 3D Community Group has been collaboratively considering common challenges and potential solutions to key areas, with major 3D developers and researchers, and ongoing dialogue with VIGIE2020/654 study colleagues, forming the IIIF 3D Technical Specification Group, engaging even more widely with other specialists and representatives across user communities and standards bodies.

Particularly, in heterogeneous environments with terminals and networks having different capabilities. The author discusses the home media access using a real-world evaluation of existing home systems. The author compares these evaluations to a Web-based approach and show how the use of the home network resources can be significantly improved for sharing and browsing media items and folders.

Abstract The World Wide Web is like an encyclopaedia, a telephone directory, a record collection, a video shop, and Speakers’ Corner all rolled into one and accessible through any computer. It has become so successful that to many it is synonymous with the Internet; but in reality the two are quite different. The Internet is like a network of electronic roads criss-crossing the planet—the much-hyped information superhighway. The Web is just one of many services using that network, just as many different kinds of vehicle use the roads. On the Internet, the Web just hap pens to be by far the most popular. The arrival of the Web in 1990 was to the Internet like the arrival of the internal combustion engine to the country lane. Internet transport would never be the same again.

Texto completo da fonteResumo:
Internet users are bombarded every day with various ads, and they try to block them in all possible ways. If they do not block them, they usually pay little attention to them. Therefore, ads need to be creative and provide as much relevant information as possible about the advertised product or service at a glance in order to lead to conversions. For this purpose, the benefits of infographics can be used very well, in addition to dynamic forms of ads that consist of audio and video elements, especially in a responsive web environment. This type of advertising is also great for posting on social media, where the flow of information and responses is very fast. Infographics actually represent a visual presentation of information through a combination of typography, symbols, pictograms, shapes, and colours and are used to present complex information quickly and clearly. The use of infographics as one of the multimedia elements in digital advertising contributes to the optimization of advertising content, which also contributes to SEO optimization. To investigate the extent to which infographics in digital advertising can contribute to the optimization of advertising content in a responsive web environment, A/B testing of multimedia advertising content presented through infographics and content that contained all relevant information about the advertiser and was not presented in the form of an infographic was conducted on two types of screens. The A/B testing model itself provides the opportunity to maximize conversion rates, but it also provides a significant increase in knowledge about how advertising content is presented. It can also establish a set of optimized practices for multimedia elements of ad content. The proposed testing model provides the perfect opportunity to properly test your ad before launch. The same analogy can be applied to other multimedia elements used to create ads, such as photos, animations, colours, content management system elements, etc. The obtained results provide valuable information about infographics possibilities in advertising content optimization in a responsive web environment because they load faster, are suitable for small screens, and do not tire users.

Sociedade Brasileira de Computação, 2020. http://dx.doi.org/10.5753/webmedia_estendido.2020.13065.
Texto completo da fonteResumo:
People with visual impairments suffer from the incapacity to understand contextual information in videos, such as the place where characters are, or any other non-spoken actions in general. Some content creators address this issue by providing a secondary audio to describe such information, called Audio Descriptions (ADs). How- ever, some works in the literature have highlighted that people with visual impairment are usually not able to completely understand scene changes based only on characters’ voices or traditional ADs. Moreover, traditional ADs do not completely describe some of the important visual information, such as the background scenery (e.g. colors, furniture) and characters’ details (e.g. blond woman using a red dress). In this work, we propose incrementing the traditional AD techniques with the usage of interactive video features present in TV systems. More precisely, the proposed interactivity enables users to access specialized AD for different visual information (e.g., scene, scenario, character). To support the development of such interactive content, we present an application template, which helps to create the final interactive-enhanced video application. Asa proof of concept for our approach, we created an interactive AD for an independent video mainly composed of visual information, with only a few talks.

Texto completo da fonteResumo:
Before the COVID-19 pandemic, video was already one of the main media used on the internet. During the pandemic, video conferencing services became even more important, coming to be one of the main instruments to enable most social and professional human activities. Given the social distancing policies, people are spending more time using these online services for working, learning, and also for leisure activities. Videoconferencing software became the standard communication for home-office and remote learning. Nevertheless, there are still a lot of issues to be addressed on these platforms, and many different aspects to be reexamined or investigated, such as ethical and user-experience issues, just to name a few. We argue that many of the current state-of-the-art techniques of Artificial Intelligence (AI) may help on enhancing video collabo- ration services, particularly the methods based on Deep Learning such as face and sentiment analyses, and video classification. In this paper, we present a future vision about how AI techniques may contribute to this upcoming videoconferencing-age.

Proper positioning of temperature sensors is required to minimize error in measurements of thermal diffusivity. Calculating the proper position of these sensors a priori, however, requires knowing the very thermophysical properties of the material one is testing. Presented here are calculations illustrating how IR video might be used to optimize a biaxial, pulsed thermal diffusivity measurement system. Results will be shown for representative elastomers.

Texto completo da fonteResumo:
This paper investigates the pivotal role of open Web Application Programming Interfaces (APIs) in enhancing business agility. It focuses on how APIs facilitate rapid adaptation to technological changes, integration of diverse software systems, and improve responsiveness to market dynamics. The primary objective is to explore and articulate effective API integration strategies that enable businesses to optimize operational efficiency and decision-making processes. The research methodology encompasses a comprehensive review of existing literature on the evolution and current state of open Web APIs. This theoretical foundation is supplemented by practical insights derived from multiple case studies of businesses that have successfully implemented API strategies. The study identifies several best practices in API integration that substantially enhance business agility. These include the adoption of RESTful APIs for their simplicity and versatility, the implementation of robust security protocols to safeguard data, and the strategic management of API lifecycles to maintain system integrity and relevance. The research also highlights the importance of a structured approach to API governance and the potential of emerging technologies, such as machine learning, to automate and optimize API functionalities.

Texto completo da fonteResumo:
This paper describes an interactive web-based design tool, developed by using a web-based server application, for the three most common snap-fit features that are the cantilever hook, post & dome and bayonet & finger. Response surface equations that predict each snap-fit feature’s performance were applied in this web-based design tool. This web-based design tool also applied constraint management (CM), which helps the designers switch the input and output on the fly and prevent over-constraint. Two other constraint management modules were applied. The first one is sensitivity analysis module used to determine the input’s dependency to a specified output also applied in the design tool. The second one is correction advisor module used to see how much each dependent input’s value should change if one output changes to a new value. Two optimization modules, single-objective optimization and multiple-objective optimization, are applied to optimize the performance of snap-fit features. Finally a real design case for cantilever hook was conducted and the results were compared to experiment results.

Texto completo da fonteResumo:
Recent coronavirus lockdowns have had a significant impact on how students study. As states shut down schools, millions of students are now required to study at home with pre-recorded videos. This, however, proves challenging, as teachers have no way of knowing whether or not students are paying attention to the videos, and students may be easily distracted from important parts of the videos. Currently, there is virtually no research and development of applications revolving specifically around the subject of effectively taking digital notes from videos. This paper introduces the web application we developed for streamlined, video-focused auto-schematic note-taking. We applied our application to school-related video lectures and conducted a qualitative evaluation of the approach. The results show that the tools increase productivity when taking notes from a video, and are more effective and informational than conventional paper notes.
