Recently articles in Newspapers, University News Bulletins and Scientific Literature report about negative aspects of the wellbeing of students caused by COVID-19 epidemic. Half of the students have mental problems and don't participate in the teaching learning process anymore ...

The areas of many cities in the Netherlands are covered by a network of stationary sensors, measuring special components of air pollution such as CO2, NO2, PM2.5 and PM10. The pollution with fine dust along roads, surrounding and crossing the city is primarily related to traff ...

In 1979 Fukushima developed a hierarchical, multilayered neural network called Neocognitron and used it for the automatic recognition of handwritten Japanese symbols. We combined the Neocognitron classifier with a special image and segment processor and applied the system in 2001 ...

The INTERSPEECH 2021 computational paralinguistics challenge

COVID-19 cough, COVID-19 speech, escalation & primates

The INTERSPEECH 2021 Computational Paralinguistics Challenge addresses four different problems for the first time in a research competition under well-defined conditions: In the COVID-19 Cough and COVID-19 Speech Sub-Challenges, a binary classification on COVID-19 infection ha ...

The Corona crisis limits the mobility of people and it proves that many people have an increased body mass index. A lot of people want to increase their fitness and to boost their immune system. There is a run-on fitness schools and fitness equipment for the home environment. ...

Social media play an important role in crisis events. People in crisis events can report their observations of the crisis environment, and their mental and physical state. They can ask for help or assistance via Twitter. Some studies report, that some or a lot of compassion, c ...

Current route planners on smart phones or special routing devices try to minimize the traveling time. But many users are no longer interested in the shortest route in time but they prefer a healthier route. In many smart cities there is a centralized distributed network of sen ...

Last year's we can observe an enormous grow of surveillance systems in the public domain. In many countries surveillance systems are under discussion because of the privacy aspects of people. In the nineties many multimodal systems were developed for surveillance in Dutch trains. ...
A Smart City can be considered as an open living lab, where new technology will be developed, implemented and tested. The focus of smart cities in this paper is on the safety of citizens, sustainable energy, risk prevention of disasters, smart transport systems using information ...

In designing a course a teacher defines the educational goals, selects the teaching material and the way of assessment and finally defines a didactic model. In this didactic model the teacher defines his way of teaching taking into account the different ways of learning. Stude ...

The ETN FETCH project is about Future Education and Training. One of the goals was to develop new didactic models and to include social media in the process of teaching and learning. Some new didactic models have been developed. We will report about them in this paper. FETCH part ...
The paper is about the development of a MOOC on the flooding of the river Vltava in the Czech country. The MOOC has been designed as a serious game. Students from all over the world are invited to take part in the management team to reduce the negative impact of the flooding. The ...
Recently we observe an enormous grow of Massive Open Online Courses (MOOCs). But it proves that the dropout rates of MOOCs are very high. One of the main causes are missing of necessary capabilities of students, inability of students to manage their study and a missing appropriat ...
Many e-learning tools enable students and teachers to send messages to each other. But it proves that this facility is hardly used by students. Social media are used by students on a large scale but the topic of conversation is usually out of the study domain. The challenge of ed ...
Many car incidents happen because the driver falls asleep. The onset of micro-sleeps can be detected by decreasing activity of alpha brain waves and increasing activity of delta brain waves. To develop an automated system for micro-sleeps detection an analysis tool for EEG record ...
A smart city is supposed to be a safe city. At this moment we observe multiple cameras in around public buildings and along streets to detect suspicious behavior. Samples of the video footage is monitored 24/7 by operators in control rooms. Currently the recorded videos are visua ...
Technically e-learning material can be downloaded from a PC environment to a mobile phone environment. But the context, environment, physical limitations of a mobile phone, sets limits to a mobile learning environment. The didactic model cannot be transferred usually from e-learn ...
In case of disaster people want to escape from the dangerous area (a building or an area of a city). Because of changing environment dynamic routing is requested. The main idea is to provide some actors involved in crisis situations with PDAs connected via a wireless network. The ...
