Realization of simulations for blinded internal pilot study based on web

AbstractMisspecification of the designing parameters in the planning of a controlled clinical trial may yield an underpowered or an overpowered study. Internal pilot study, a kind of adaptive design, has gained increased attention for its allowing for sample size adjustment, especially blinded sample size adjustment that do not affect the type I error rate. Several methods were proposed to implement internal pilot design in recent years and some software emerges to simulate or implement it. But most of the software is only running on a stand-alone terminal or Client/Server(C/S) mode. We develop a system to simulate it based on Browser/Server(B/S) mode and realized on web. It allows the web users to input corresponding parameters from the web browser such as Internet Explorer to make simulations. The system was constructed with generic database schema design method and coded with Microsoft Visual Basic and Active Server Pages (ASP) programming languages. Web users on internet can use the system to make blinded variance estimate, sample size adjustment and randomization test for internal pilot study. The application of the simulation is demonstrated through an example. Not only blinded sample size adjustment is implemented but also a randomization test is performed. With applications of blinding one-sample variance for sample size recalculation and randomization test, the type I error rate is also controlled successfully

Attention visual

This research presents an innovative approach to improving visual-spatial attention using a research tool based on the web. Recognizing the significant role visual-spatial attention plays in everyday life and cognitive function for humans, this research was undertaken with the aim of developing a user-friendly, accessible web-based tool called Attention Visual (attentionvisual.com) to enhance this crucial cognitive skill. This tool also facilitates data collection, potentially accelerating the pace and enhancing the quality of related research. Both qualitative and quantitative methods were utilized for data collection and analysis. In order to stimulate improvements in visual-spatial attention, the tool’s algorithm was structured to adjust task difficulty according to the user’s performance; heightened performance would yield more challenging tasks, whereas lower performance would result in easier tasks, fostering an adaptive and progressive learning environment. The main hypothesis that underlies this research was that regular use of this tool could result in measurable enhancements in visual-spatial attention. This has potential benefits for various population groups, from athletes to individuals with certain cognitive conditions. The results of the research validate this hypothesis, demonstrating the effectiveness of the webbased tool in enhancing visual-spatial attention and indicating that the design elements of the tool have a positive impact on user performance. The research additionally highlighted a wide range of participant diversity, thanks to the online nature of the tool, enhancing the robustness and generalizability of the data collected. These findings contribute significantly to the fields of cognitive science, neuroplasticity, and digital tool development, offering valuable insights for future research. They demonstrate the effectiveness of web-based tools in cognitive science research and suggest potential avenues for future investigation, such as exploring other aspects of visual cognition or the application of such tools in practical settings like cognitive therapy and rehabilitation

Interactive and Live Program Construction

In the highly technological and advanced society we live nowadays, it is essential to explore new development approaches in order to increase the efficiency and flexibility with which software is built. Our work focuses on the design and conception of a live graphical environment to allow for incremental and interactive construction of web applications through visual manipulation interactions. Our research is introduced in the context of a prototype, Live Programming, that provides a style of incremental and agile development of web applications, allowing for efficient updates of code and data. However, the construction of a web application through the existing coding environment is still slow and not as flexible as one would wish. This is due to the fact that its user interface is based on text editors, resulting in a heavy reliance on computer code to build these applications. The goal of our work consists on the conception of a visual construction model and graphical environment that interacts with the Live Programming system, allowing to incrementally develop web applications through the manipulation of visual symbols on the screen. The user does not need to program: instead, our tool automatically generates code according to the user’s manipulation of the visual components. The user must then be able to visually define the data model, queries, logical operations and presentation views (for example, html pages). We aim, as well, at idealizing and proposing creative and convenient techniques to program visualization and methods to visually organize the structure of a program, in order to help the user comprehending the relationships between elements and their responsibility within the system. This way, developers leverage an agile and interactive approach to efficiently deal with increasingly demanding requirements throughout development

Data analytics for image visual complexity and kinect-based videos of rehabilitation exercises

With the recent advances in computer vision and pattern recognition, methods from these fields are successfully applied to solve problems in various domains, including health care and social sciences. In this thesis, two such problems, from different domains, are discussed. First, an application of computer vision and broader pattern recognition in physical therapy is presented. Home-based physical therapy is an essential part of the recovery process in which the patient is prescribed specific exercises in order to improve symptoms and daily functioning of the body. However, poor adherence to the prescribed exercises is a common problem. In our work, we explore methods for improving home-based physical therapy experience. We begin by proposing DyAd, a dynamically difficulty adjustment system which captures the trajectory of the hand movement, evaluates the user's performance quantitatively and adjusts the difficulty level for the next trial of the exercise based on the performance measurements. Next, we introduce ExerciseCheck, a remote monitoring and evaluation platform for home-based physical therapy. ExerciseCheck is capable of capturing exercise information, evaluating the performance, providing therapeutic feedback to the patient and the therapist, checking the progress of the user over the course of the physical therapy, and supporting the patient throughout this period. In our experiments, Parkinson patients have tested our system at a clinic and in their homes during their physical therapy period. Our results suggests that ExerciseCheck is a user-friendly application and can assist patients by providing motivation, and guidance to ensure correct execution of the required exercises. As the second application, and within computer vision paradigm, we focus on visual complexity, an image attribute that humans can subjectively evaluate based on the level of details in the image. Visual complexity has been studied in psychophysics, cognitive science, and, more recently, computer vision, for the purposes of product design, web design, advertising, etc. We first introduce a diverse visual complexity dataset which compromises of seven image categories. We collect the ground-truth scores by comparing the pairwise relationship of images and then convert the pairwise scores to absolute scores using mathematical methods. Furthermore, we propose a method to measure the visual complexity that uses unsupervised information extraction from intermediate convolutional layers of deep neural networks. We derive an activation energy metric that combines convolutional layer activations to quantify visual complexity. The high correlations between ground-truth labels and computed energy scores in our experiments show superiority of our method compared to the previous works. Finally, as an example of the relationship between visual complexity and other image attributes, we demonstrate that, within the context of a category, visually more complex images are more memorable to human observers

Abmash: Mashing Up Legacy Web Applications by Automated Imitation of Human Actions

Many business web-based applications do not offer applications programming interfaces (APIs) to enable other applications to access their data and functions in a programmatic manner. This makes their composition difficult (for instance to synchronize data between two applications). To address this challenge, this paper presents Abmash, an approach to facilitate the integration of such legacy web applications by automatically imitating human interactions with them. By automatically interacting with the graphical user interface (GUI) of web applications, the system supports all forms of integrations including bi-directional interactions and is able to interact with AJAX-based applications. Furthermore, the integration programs are easy to write since they deal with end-user, visual user-interface elements. The integration code is simple enough to be called a "mashup".Comment: Software: Practice and Experience (2013)
