The Integration of Remote Sensing and Ancillary Data

Obtaining up-to-date information concernmg the environment at reasonable costs is a challenge faced by many institutions today. Satellite images meet both demands and thus present a very attractive source of information. The following thesis deals with the comparison of satellite images and a vector based land use data base of the City of Vienna. The satellite data is transformed using the spectral mixture analysis, which allows an investigation at a sub-pixel level. The results of the transformation are used to determine how suitable this spectral mixture analysis is to distinguish different land use classes in an urban area. In a next step the results of the spectral mixture analysis of two different images (recorded in 1986 and 1991) are used to undertake a change detection. The aim is to show those areas, where building activities have taken place. This information may aid the update of data bases, by limiting a detailed examination of an area to those areas, which show up as changes in the change detection. The proposed method is a fast and inexpensive way of analysing large areas and highlighting those areas where changes have taken place. lt is not limited to urban areas but may easily be adapted for different environments.

How the Shareplace Pilot Regions Deal with the Corona Crisis

The Interreg Central Europe co-funded three-year project SHAREPLACE (“Shared mobility and Regional transport integrated Planning for a better connected Central Europe”) addresses, among others, the development and implementation of new mobility services in order to enhance the existing transport network based on the current needs of travellers. These new tools and services are being developed for five pilot regions, located in Croatia, Germany, Hungary and Italy. One objective of the project is to show how a co-design approach can support the design and implementation of new mobility services. Although the situation in terms of availability and quality of services as well as strategic planning processes are quite different in all pilot regions, they all profited from using living labs and stakeholder involvement for the development and design of services. Due to COVID-19 the situation change and the pilot regions are facing new challenges. How can participation work in times of COVID-19 and social distancing? This paper shows how the SHAREPLACE pilot regions deal with the new situation and which new experiences they made

Challenges and barriers for a sustainable transport system – exploring the potential to enact change

This report is divided into three parts; the first part summarizes the results from a workshopconducted within the TRANSFORuMproject. The second part presents the results of interviewscarried out with different experts discussing the different goals and their perceptionsof what might prevent or delay appropriate implementation. The third part is based on a literature reviewdiscussing how to overcome or remove the various barriersand challenges. The overall aim ofthe studies presented in this report is to identify barriers but also to present necessary steps which need to be takenin order to help achieving the goals.The term "Barrier" relates to something which prevents some form of progress or movement, while "Challenge" can be something difficult but also something which is regarded as stimulating; or an opportunity

Co-translational capturing of nascent ribosomal proteins by their dedicated chaperones

Exponentially growing yeast cells produce every minute >160,000 ribosomal proteins. Owing to their difficult physicochemical properties, the synthesis of assembly-competent ribosomal proteins represents a major challenge. Recent evidence highlights that dedicated chaperone proteins recognize the N-terminal regions of ribosomal proteins and promote their soluble expression and delivery to the assembly site. Here we explore the intuitive possibility that ribosomal proteins are captured by dedicated chaperones in a co-translational manner. Affinity purification of four chaperones (Rrb1, Syo1, Sqt1 and Yar1) selectively enriched the mRNAs encoding their specific ribosomal protein clients (Rpl3, Rpl5, Rpl10 and Rps3). X-ray crystallography reveals how the N-terminal, rRNA-binding residues of Rpl10 are shielded by Sqt1’s WD-repeat β-propeller, providing mechanistic insight into the incorporation of Rpl10 into pre-60S subunits. Co-translational capturing of nascent ribosomal proteins by dedicated chaperones constitutes an elegant mechanism to prevent unspecific interactions and aggregation of ribosomal proteins on their road to incorporation

Tracking Quality of Low-Cost GNSS-Receivers. GI_Forum 2013 – Creating the GISociety|

GNSS receivers are an essential part of modern technological devices. Mobile phones, digital cameras, and car navigational systems are only some examples for tools using GNSS technology. These sensors can be used to support other tasks as well. A simple example is fleet management where the car navigation systems can provide data on the current position, intended target and selected route of the vehicles. However, utilizing data requires information on its quality, in this case on the positional accuracy of the sensors. This quality was checked for GNSS receivers in different mobile phones and a tracking device. Tracking of vehicles is usually restricted to a navigational network. In many cases, several lines may be in parallel with small lateral distance, e.g., lanes on a street, parallel streets, or parallel rail tracks. In these cases, the lateral quality is of higher importance than the longitudinal quality. Thus we concentrated on this aspect of the quality

Exploring the Living Lab approach for improving the interoperability between local, regional and transnational transport networks

Transport systems in Central Europe often show a lack of integration between different transport networks and modes. Linking the Trans-European Network to the regional passenger transport system is a challenge, linking both to flexible mobility services such as sharing services, on demand transport etc. on a local level, is an even bigger one. However, the potential of a successful integration with regard to improved service quality, increased accessibility and sustainability is high. The paper will outline the basic concept of Living Labs and its usability for the improvement of local, regional and transnational transport systems. The Living Lab approach will help take into account the mobility needs of different user groups when developing new services or adapting existing ones and will support these services to become more competitive and financially viable. In the Interreg-project SHAREPLACE six Living Lab sites in Austria, Croatia, Germany, Italy and Hungary will be implemented
