AbstractMachine learning components such as deep neural networks are used extensively in cyber-physical systems (CPS). However, such components may introduce new types of hazards that can have disastrous consequences and need to be addressed for engineering trustworthy systems. Although deep neural networks offer advanced capabilities, they must be complemented by engineering methods and practices that allow effective integration in CPS. In this paper, we proposed an approach for assurance monitoring of learning-enabled CPS based on the conformal prediction framework. In order to allow real-time assurance monitoring, the approach employs distance learning to transform high-dimensional inputs into lower size embedding representations. By leveraging conformal prediction, the approach provides well-calibrated confidence and ensures a bounded small error rate while limiting the number of inputs for which an accurate prediction cannot be made. We demonstrate the approach using three datasets of mobile robot following a wall, speaker recognition, and traffic sign recognition. The experimental results demonstrate that the error rates are well-calibrated while the number of alarms is very small. Furthermore, the method is computationally efficient and allows real-time assurance monitoring of CPS.

Academic Scholarship

The article discusses the decision of some problems connected with the distribution of increased state academic scholarships, such as: late submission of documents, lengthy processing of applications, the paper version of the filing documents that complicate the process of submission and consideration of applications and documents into a higher state academic scholarship, thereby increasing the burden on the members of the scholarship Commission and directorates of the institutions.The aim of this work is to find ways to improve the efficiency and accessibility of this process through an information system that will allow you to submit achievements for authentication and applications for an increased state academic scholarship online, track your position in the ranking in real time, view the achievements of other students directly from the rating system.Information system design is implemented using a new stack of information design and development approaches. The article pays special attention to the design of the database and the interface part of the application. The article presents a working web application “administration of the achievement accounting system”.

AbstractSummaryUnderstanding the spread and evolution of pathogens is important for effective public health measures and surveillance. Nextstrain consists of a database of viral genomes, a bioinformatics pipeline for phylodynamics analysis, and an interactive visualisation platform. Together these present a real-time view into the evolution and spread of a range of viral pathogens of high public health importance. The visualization integrates sequence data with other data types such as geographic information, serology, or host species. Nextstrain compiles our current understanding into a single accessible location, publicly available for use by health professionals, epidemiologists, virologists and the public alike.Availability and implementationAll code (predominantly JavaScript and Python) is freely available from github.com/nextstrain and the web-application is available at nextstrain.org.

Flood Monitoring

Abstract Urban flooding is one of the major issues in many parts of the world, and its management is often challenging. One of the challenges highlighted by the hydrology and related communities is the need for more open data and monitoring of floods in space and time. In this paper, we present the development phases and experiments of an Internet of Things (IoT)-based wireless sensor network for hydrometeorological data collection and flood monitoring for the urban area of Colima-Villa de Álvarez in Mexico. The network is designed to collect fluvial water level, soil moisture and weather parameters that are transferred to the server and to a web application in real-time using IoT Message Queuing Telemetry Transport protocol over 3G and Wi-Fi networks. The network is tested during three different events of tropical storms that occurred over the area of Colima during the 2019 tropical cyclones season. The results show the ability of the smart water network to collect real-time hydrometeorological information during extreme events associated with tropical storms. The technology used for data transmission and acquisition made it possible to collect information at critical times for the city. Additionally, the data collected provided essential information for implementing and calibrating hydrological models and hydraulic models to generate flood inundation maps and identify critical infrastructure.

The severe acute respiratory syndrome coronavirus SARS-CoV-2 pandemic brought changes in various aspects of life, including educational field. The present study reveals some of the challenges related to real-time distance learning for university students majoring in tourism in Plovdiv, Bulgaria. The study includes Bulgarian and international students in full-time and part-time bachelor's and master's tourism programs, in which real-time distance education was introduced for the first time. The current study could be a starting point for improving the organization and quality of education of Tourism students, as well as for faster overcoming of related difficulties in communication with students.

Operation Center

This paper designs and develops a real-time charger management system which keeps collecting the status information from chargers and converts control messages from the total operation center to a command predefined for charger control. RF cards complete the service chain from electric vehicles to the operation center, making the information flow bidirectional. The extended coverage of the operation control over the charging infrastructure allows an easy payment for the charging fee, based on the membership management and personalized services. A web application is implemented on the digital map of the target city for users to retrieve necessary information from the system and find the best service and chargers. The massive amount of real-time charger monitoring data is being accumulated in the database, and big data analysis will allow us to make intelligent plans for future smart grid city services.

Distance learning, where instruction is given to students despite wide separations of students and teachers, is increasingly popular. Videoconferencing, which is examined in this study, is a distance learning mode of featuring real-time interaction of students and teachers and provides sequence, real-time, vision, and actual interaction. This study focuses on learning achievement compared to that of face-to-face instruction at one fixed location. It investigates the interrelation of learning achievement, gender, emotional intelligence, and motivation. Statistical techniques are used to analyze and evaluate the data. The subjects were divided into a target group and control group. The findings were that learning achievement was similar for videoconferencing and traditional face-to-face instruction. It showed a significant relationship between emotional intelligence and learning achievement. An implication is that a judicious embedding of emotional intelligence consideration in the design and implementation of videoconferencing courses might enhance learning achievement.
