We discuss the impact of Virtual Reality, Augmented Virtuality and Augmented Reality for specific memorial locations. We show how to use a virtual studio for demonstrating an augmented reality application for a specific location in a remote session within a video conference. Augmented Virtuality is used to recreate the local environment, thus providing a context and helping the participants recollect emotions related to a certain place. This technique demonstrates the advantages of using virtual (VR) and augmented (AR) reality environments for rapid prototyping and pitching project ideas in a live remote setting.

These are web applications with “super-powers” which are meant to provide the kinds of user experiences previously only native mobile applications could. Therefore they are able to match native applications in their capabilities but still thrive on the reachability of the web. They achieve this by implementing certain characteristics which originate from innovative standards and sophisticated best practices. Conveniently, as it is the web, PWAs are working seamlessly cross-platform. One of the closest things to a PWA so far may be an application created with the NativeScript framework. Such an application is also developed with web technologies yet able to use any native interface directly. This is made possible by using a designated runtime for mediating between JavaScript and the mobile system. Eventually, NativeScript is able to offer a high degree nativity yet also of convenient abstraction during development. This paper is set out to deliver further insight into both approaches by contrasting them based on the characteristics of PWAs. For this purpose, these characteristics are elaborated and adjusted to be applicable to native mobile applications. Hence a reasonable basis for what to expect from a native application is derived. Then NativeScript is assessed on this basis by the means of transferable concepts and technologies as well as a prototypic mobile application. Finally, an informed discussion and conclusion is performed based on the results. The comprehensive characteristics of PWAs resolve previous shortcomings with well thought out concepts and new technologies. These are transferable to native mobile applications to a far extent and may also be put into practice with NativeScript. The framework’s approach may be very well called ingenious, however, in the long run it might fall short of the innovative concept of PWAs. Having said this, it is still able to serve as a practical measure for creating appealing user experiences for multiple systems with arguably little effort. Due to large overlap a transformation between the two application types is a realistic option. Either way, web technologies are far from what they used to be and it is exciting to see how the mobile and web landscape will evolve in the future.

This concentration is linked to the increase of number of cars, construction areas, industries and other emission sources. However, fixed measurement stations, mostly operated by environmental agencies, are limited in numbers and cannot cover a large area in monitoring. For this reason, to overcome this drawback, mobile measurements of the variability of gases (such as O3, NO, NO2) and particulate matter concentration were carried out during this study using an instrumented car. This car was able to deliver measurement results of all these compounds in a large area. The experimental results in this work demonstrate a large spatial variability of gases and fine particulate matters mainly depended on the traffic density and the location. These effects are especially obvious in the city core and the high traffic roads. In terms of fine particulate matter, this becomes evident for PM 10 and PM 2.5, where the mass and number concentration increases with arriving these zones.

It is still one of the major problems of air pollution in Germany. The limit values of fine particulate matter PM10 are often exceeded in bigger German cities. Therefore the level of fine particulate matter and other air pollutants are routinely monitored at single hot spots in the cities by measurement stations of the environmental state agencies. However, it is of high interest, what levels of concentrations of fine particulate matter are to be found in those areas, where no measurement stations are placed. Moreover, it is important to know, how strong exceedings of fine particulate matter concentrations can be influenced by meteorological conditions. In this paper fine particulate matter concentrations are measured with a car, which was equipped with measurement systems for fine particulate matter and which was driving through industrial and rural areas of the state North Rhine Westphalia in Germany. By this means it was possible to measure coarse and fine fractions of particulate matter continuously during driving. In this way the horizontal variation of fine particulate matter could be investigated throughout the state. The measurements comprised dust concentrations of the fractions PM10 (coarse), PM2.5 (more fine) and PM1(very fine), which are addressed within the European environmental legislation. Moreover, every second during driving the full size distribution of particles between 250 nm and 32 μm diameter was measured. Therefore it could be investigated, at what places more bigger or more smaller particles were present under specific meteorological conditions. The mobile car measurements were performed as a case study in a situation with a strong meteorological inversion layer. The mobile measurements of the horizontal variation of fine particulate matter in industrial and rural areas are compared with model prediction calculations. Moreover, using backward trajectories a source appointment of the fine particulate matter could be performed.
