Advanced UI test automation (AUTA) for BIOS validation using OpenCV and OCR

<p>Basic input output system (BIOS) validation is performed on both graphical user interface (GUI) and command-line interface (CLI) by a test engineer. Keyboard and mouse are used to insert test cases commands into system under test (SUT). Test engineer monitors test cases progress on a monitor for validation. This method is time-consuming and relatively more expensive than automation. In this project we designed an independent automation system that able to mimic human interaction in BIOS validation. The approach can be divided into two main parts. The first part is the input device to enter commands into SUT and the second part is the advanced image recognizer. The keyboard and mouse emulator is used as an input device to reproduce test commands and send them to an SUT. The image analyzer algorithm is developed using OpenCV and optical character recognizer (OCR) tools to help automate some test challenges. Our result shows that advanced user interface (UI) test automation (AUTA) can perform a 125 test cases within 5 hours compared to 48 hours for a human to complete the job.</p>

HOW TO MAKE ADVANCED ONLINE USER STUDIES MEANINGFUL

It is of vital importance to explore and understand future users' needs and requirements in the early phases of the product development process. However, in times of social distancing meeting users might not be possible. The project reported on in this paper has investigated the possibilities of conducting advanced user studies online. In total 30 small experimental studies have been conducted. Common digital tools that were used were e.g. Zoom, Teams, Mural, Miro, Snapchat, and Instagram.The data was analyzed in a thematic content analysis by the authors on Mural. Identified challenges were excluding not tech-savvy user groups, missing out on interpersonal interaction and observations, as well as difficulties creating participant commitment and trust. On the positive side were perceived efficiency, a more levelled power distribution between participants, and ease of engagement and data retrieval for tech-savvy users.Identified best practices included lowering social barriers through warm up activities and techniques to support open discussion during workshops. Furthermore, engagement could be supported through private social media groups, regular reminders, as well as clear communication of purpose and goal of the activities.

PROGRAMMING METHOD OF THE MDR32F9Q2I MICROCONTROLLER IN CONTROL AND MONITORING TASKS

Разработана методика, обеспечивающая полный спектр организации работ по программированию микроконтроллера MDR32F9Q2I, которая позволяет получить, в частности, системы управления и мониторинга источников вторичного электроснабжения. Программирование микроконтроллера, построенного на базе высокопроизводительного процессорного RISC ядра ARM, производилось в интегрированной среде разработки Eclipse IDE в операционной системе Windows 10 Pro. Интегрированная среда разработки Eclipse выбрана как наиболее удобная и доступная среда, поддерживает всевозможные типы языков программирования и непрерывную компиляцию. В настоящее время 16- и 32-битные микроконтроллеры быстро набирают популярность в сфере промышленных задач. Их применение обусловлено постоянно возрастающей сложностью задач, жесткими требованиями к производительности интегрируемых контроллеров управления, необходимостью иметь в электронных устройствах развитые органы пользовательского управления. Представленный стенд для моделирования, использующий интерфейсный мост между шинами I2C и 1-Wire - DS2482-100, преобразует протоколы между управляющим I2C микроконтроллером (мастером) и ведомыми 1-Wire устройствами, а также контролирует скорости нарастания и уменьшения напряжения в линии. Основой для написания класса DS2482 являются заголовочные файлы Arduino.h и OneWire.h, которые находятся в свободном доступе In this article, we developed a technique that provides a full range of organization of works on programming the MDR32F9Q2I microcontroller, which allows you to obtain control and monitoring systems for secondary power supply sources. The microcontroller based on the high-performance ARM RISC processor core was programmed in the Eclipse IDE on the Windows 10 Pro operating system. We chose the Eclipse integrated development environment as the most convenient and accessible environment, it supports all kinds of programming languages and continuous compilation. Currently, 16- and 32-bit microcontrollers are rapidly gaining popularity in the field of industrial tasks. Their use is due to the ever-increasing complexity of tasks, stringent requirements for the performance of integrated controllers, the need to have advanced user controls in electronic devices. We present a simulation stand that uses an interface bridge between the I2C and 1-Wire buses - DS2482-100, converts protocols between the I2C microcontroller (master) and 1-Wire slaves, and also controls the voltage rise and fall rates in the line. The basis for writing the DS2482 class is the Arduino.h and OneWire.h header files, which are freely available

Lens Library to Facilitate Composing of Virtual Scene for Optic Experiments

While the mathematical modeling of optical phenomena, a computer calculation is often performed, confirming the conclusions made. To do this, a virtual computer model of the optical installation is created in the form of a 3D scene. Also, virtual scenes are often used in training when creating presentations. This paper describes the SphL library, which provides a convenient assignment of spherical lenses and the calculation of the interaction of linear polarized light rays with them. It is focused on applications that use ray tracing. It is known that light of any polarization can be represented on the basis of the mentioned one. The reflected and all rays passing through the lens that arise due to internal reflections are calculated from the ray incident on the scene object. The number of internal reflections is set by the parameter. All output rays are calculated based on the application of Fresnel’s equations and are characterized by intensity values and polarization parameters. In this version of SphL, the main objects at the end–user level are spherical lenses, since they are most often used in optic installations. They are constructed on the basis of the application of the set-theoretic intersection of geometric primitives: a half-space, a sphere, a cone, a cylinder and their complements to the scene space. An advanced user can build their own objects by analogy, for example, cylindrical lenses.

Web-Based Data Visualization Platform for MATSim

There are many tools available for analyzing MATSim transport simulation results, both open-source and commercial. This research builds a new open-source visualization platform for MATSim outputs that is entirely web-based. After initial experiments with many different web technologies, a client-server platform design emerges which leverages the advanced user interface capabilities of modern browsers on the front-end, and relies on back-end server processing for more processor-intensive tasks. The initial platform is now operational and includes several aggregate-level visualizations including origin–destination flows, transit supply, and emissions levels as well as a fully disaggregate traffic animation visualization. These visualizations are general enough to be useful for various projects. Further work is needed to make them more compelling and the platform more useful for practitioners.

Curriculum to Introduce Critical Care Nurses to Extracorporeal Membrane Oxygenation

Background Despite the growing use of extracorporeal membrane oxygenation (ECMO) in intensive care units (ICUs), no standardized ECMO training pathways are available for ECMO-naive critical care nurses. Objectives To evaluate a critical care nurse ECMO curriculum that may be reproducible across institutions. Methods An ECMO curriculum consisting of a basic safety course and an advanced user course was designed for critical care nurses. Courses incorporated didactic and simulation components, written knowledge examinations, and electronic modules. Differences in examination scores before and after each course for the overall cohort and for participants from each ICU type were analyzed with t tests or nonparametric equality-of-medians tests. Differences in postcourse scores across ICU types were examined with multiple linear regression. Results Critical care nurses new to ECMO (n = 301) from various ICU types participated in the basic safety course; 107 nurses also participated in the advanced user course. Examination scores improved after completion of both courses for overall cohorts (P &lt; .001 in all analyses). Median (interquartile range) individual score improvements were 23.1% (15.4%-38.5%) for the basic safety course and 8.4% (0%-16.7%) for the advanced user course. Postcourse written examination scores stratified by ICU type, compared with the medical ICU/cardiovascular ICU group (reference group), differed only in the neurovascular ICU group for the basic safety course (percent score difference, −3.0; 95% CI, −5.3 to −0.8; P = .01). Conclusions Implementation of an ECMO curriculum for a high volume of critical care nurses is feasible and effective.
