Assessing energy consumption in scalable semi-autonomous destination-based E-platoons: A multiplayer approach

Recent developments in connected and automated vehicle technologies have opened up new possibilities but also posed enduring challenges. One of the primary challenges is the efficient coordination of vehicles in urban environments, specifically through scalable and destination-based platooning. While considerable research has focused on platooning with a limited number of vehicles demonstrating seamless connectivity and coordination on highways, there remains a significant gap in understanding and implementing scalable platoons in more dynamic urban settings. This paper bridges these gaps by developing a novel extension to the 3DCoAutosim simulation platform. Our model introduces ’Scalable Semi-autonomous Destination-based Multiplayer E-Platoons’, accommodating different automation levels and simulation characteristics of vehicles in five distinct platoons. We employed seven electric vehicles to create these platoons, each consisting of an autonomous lead vehicle, followers that are either autonomous or semi-autonomous (accompanied by drivers), customised according to the specific requirements of each platoon. Utilising Time Series Analysis, Multiple Linear Regression and a comprehensive, comparative scenario-based analysis, we assessed and validated our developed model’s impact on battery energy consumption under varying road slopes and car-following models. Our assessment employs real-world trip data from Upper Austria, with results indicating a potential reduction in total battery energy consumption when operating in platoon mode.

A Machine Learning Approach to Adapt Local Land Use Planning to Climate Change

The impacts on living conditions and natural habitats deriving from planning decisions require complex analysis of cross-acting factors, which in turn require interdisciplinary data. At the municipal level, both data collection and the knowledge needed to interpret it are often lacking. Additionally, climate change and species extinction demand rapid and effective policies in order to preserve soil resources for future generations. Ex-ante evaluation of planning measures is insufficient owing to a lack of data and linear models capable of simulating the impacts of complex systemic relationships. Integrating machine learning (ML) into systemic planning increases awareness of impacts by providing decision-makers with predictive analysis and risk mitigation tools. ML can predict future scenarios beyond rigid linear models, identifying patterns, trends, and correlations within complex systems and depicting hidden relationships. This article focuses on a case study of single-family houses in Upper Austria, chosen for its transferability to other regions. It critically reflects on an ML approach, linking data on past and current planning regulations and decisions to the physical environment. We create an inventory of categories of areas with different features to inform nature-based solutions and backcasting planning decisions and build a training dataset for ML models. Our model predicts the effects of planning decisions on soil sealing. We discuss how ML can support local planning by providing area assessments in soil sealing within the case study. The article presents a working approach to planning and demonstrates that more data is needed to achieve well-founded planning statements.

Prehistoric Recycling Explained in a Playful Way: The Pfahlbauten Wimmelbild—An Interactive Digital Mediation Tool Designed by Young People

With the “Talents Internship program” established by the Austrian Research Promotion Agency (FFG, Österreichische Forschungsförderungsgesellschaft), 14- to 17-year-old students from various school types visited the Natural History Museum and the Kuratorium Pfahlbauten in summer 2022 to gain practical experience in research. The internship focused on a sustainability approach, discussing recycling methods, the sustainable use of resources and the circular economy in prehistory. The UNESCO World Heritage “Prehistoric Pile Dwellings around the Alps” was used as a research area for the project. The project also aimed to make the content developed by the students available to the public as a digital media tool. The pupils brought an illustration of a prehistoric lake shore settlement to life and created an interactive image available at the website of Kuratorium Pfahlbauten. Various scenes of the illustration have been augmented with animations created by the students of HTL Spengergasse in Vienna. Students from federal secondary schools from Vienna (Stubenbastei) and Upper Austria (Traun) researched the information about the objects and wrote texts that, as a description of the animated videos, introduce the users to the prehistoric artifact and explain the recycling process behind it. The students worked independently using the scientific literature, 140-year-old inventory books and 6000-year-old objects from the collection of the Natural History Museum Vienna. The activities and the supporting program within the internship were recorded by the students in blog posts, available at the Pfahlbauten-Blog. The co-creative approach of the FFG Talent Internship made it possible to introduce a group of school students to the process of scientific work and the communication of results. It was honored with the Creative App Award at CHNT 2023.

Examinations on small bronze items from the Hallstatt period burial ground at Mitterkirchen in Upper Austria

Abstract A partially destroyed burial ground from the Hallstatt period in the area of Mitterkirchen in Upper Austria was archaeologically investigated. The graves are dated to the Hallstatt C period corresponding to the 8th/7th century BC. Two triangular-headed nails and two lamellar “Buckel” (domed bronze plates) made of Sn-bronze were available for material investigations. One of each was subjected to metallographic examinations. The triangular-headed nail’s bronze contains about 15 wt. %Sn. The dendritic cast structure and the eutectoid phase Cu41Sn11 are clearly visible. What is noticeable is that a Cu41Sn11 layer formed in some areas of the surface. The lamellar Buckel’s microstructure is recrystallized and exhibits only a few deformation twins. Its bronze contains about 13 wt. %Sn. Hence, only very little Cu41Sn11 is present. Elongated Cu2S precipitates indicate that the initial sheet was manufactured by fine forging.

Three prolonged outbreaks of metallo-β-lactamase-producing Pseudomonas aeruginosa in an Upper Austrian hospital, 2017-2023.

The significance of our work lies in the successful resolution of three prolonged outbreaks of MBL-Pa infections in a hospital in Upper Austria. Through a comprehensive epidemiological investigation coupled with WGS-based typing of P. aeruginosa isolates, the study identified three distinct genomic clusters responsible for prolonged outbreaks involving 47 cases. The investigation pinpointed sinks in the ICU washroom as the likely source of infection for two of the clusters. The study demonstrates the effectiveness of control measures such as hand hygiene, gowning, patient isolation, screening, and disinfection in stopping further transmission and bringing the outbreaks to a close. This underscores the critical role of genomic surveillance and control measures, particularly in high-risk settings like ICUs, in reducing nosocomial transmission of MBL-Pa infections.

The mediating role of social relationships between perceived classroom management and adolescents' attitudes toward school: a multilevel analysis

Social relationships in the school context – particularly teacher-student relationships and peer relationships – are related to students’ positive attitudes toward school, and consequently are of great importance regarding various aspects of learning and instruction. This can be concluded from studies that examine the influence of social integration on motivation, learning emotions, and positive attitudes toward school as an institution. Additionally, social relationships are closely related to the teacher’s style of instruction and student perceptions of the learning environment provided. However, there is little research so far, on the extent to which positive social relationships mediate correlations between aspects of teaching quality i.e., classroom management, and students’ positive attitudes toward school. Both classroom management and school-related social relationships are constructs that are assumed to be perceived similarly by students within one school, who experience similar conditions in regard to the intensity and frequency of common lessons. However, there are few research findings regarding shared assessments of classroom management and it’s correlations with teacher-student relationships by students within one school or class, and to date no results regarding the shared assessments of peer relationships. Therefore, the current study aimed to examine the correlations between students’ individual and aggregated assessments of social relationships in school and classroom management, with their positive attitudes toward school. The sample consisted of N = 453 polytechnic school students in Upper Austria, from which a weighted dataset was derived. The findings from multilevel mediation analyses support the assumption of the mediating role of both teacher-student relationships and peer relationships regarding the correlation between classroom management and students’ positive attitudes toward school. However, significant correlations were found only at the individual student level.

Gosposki razbojnik Franc Jožef Vodnik (1691–1716) iz Krškega ter njegove domače in mednarodne kriminalne zveze

In 1716, Franc Jožef Vodnik, a burgher son from Krško and a travelling student, who was tried for banditry before the blood court at Šrajbarski Turn Castle near Krško together with his servant, gave descriptions of forty-three other, mostly young criminals with whom he had come into contact mainly in Vienna but also in Lower and Upper Austria. A quarter of them were students (eleven), including three who returned to the right path and became priests. A good quarter of the young men (twelve), including half of the travelling students (six), came from Slovenian territory (one from Styria and the rest from Carniola). Vodnik died of gangrene as a result of an attempted escape by jumping, and three of his accomplices from Carniola were sentenced to death the following year and executed in a group of ten criminals in the Lower Austrian town of Krems an der Donau.

Airborne Aluminum as an Underestimated Source of Human Exposure: Quantification of Aluminum in 24 Human Tissue Types Reveals High Aluminum Concentrations in Lung and Hilar Lymph Node Tissues.

Aluminum (Al) is the most abundant metal in the earth's crust, and humans are exposed to Al through sources like food, cosmetics, and medication. So far, no comprehensive data on the Al distribution between and within human tissues were reported. We measured Al concentrations in 24 different tissue types of 8 autopsied patients using ICP-MS/MS (inductively coupled plasma-tandem mass spectrometry) under cleanroom conditions and found surprisingly high concentrations in both the upper and inferior lobes of the lung and hilar lymph nodes. Al/Si ratios in lung and hilar lymph node samples of 12 additional patients were similar to the ratios reported in urban fine dust. Histological analyses using lumogallion staining showed Al in lung erythrocytes and macrophages, indicating the uptake of airborne Al in the bloodstream. Furthermore, Al was continuously found in PM2.5 and PM10 fine dust particles over 7 years in Upper Austria, Austria. According to our findings, air pollution needs to be reconsidered as a major Al source for humans and the environment.

Complete genome of a multiresistant Pasteurella multocida isolated from a diseased Austrian bovine calf.

Pasteurella multocida (P. multocida) plays an important role in bovine respiratory diseases. Here we describe the complete genome of a multiresistant P. multocida. The strain was isolated from the lung of a diseased, 4-month old, male Fleckvieh calf with a clinical history of bronchopneumonia in Upper Austria.

Transforming the Creative and Social Entrepreneurial Ecosystem: The Broker Roles of Rural Collaborative Workspaces

Creative social enterprises are increasingly emerging in rural regions, motivated by a desire to take social responsibility through creative approaches. These enterprises integrate entrepreneurial activities with creative social attributes and are sometimes set in rural collaborative workspaces (CWSs) facilitating entrepreneurial activities. Under the frame of entrepreneurial ecosystems (EEs), we argue that CWSs can be seen as brokers, who (1) link resources as liaisons, (2) hold and pass resources as gatekeepers, (3) enhance resource flows as coordinators, and (4) reproduce experiences as representatives. Against this backdrop, this paper presents a case study of two creative social enterprises in a CWS with a cooperative structure in rural Upper Austria by analyzing entrepreneurial biographies about the demand and use of entrepreneurial resources. Through a comparison between before and after the emergence of the CWS, the findings suggest that the EE for creative and social entrepreneurship undergoes two different types of transformation, a radical and a gradual one. The brokerage process of the CWS enhances local resource networks’ transformation of EE and brings the transformation in terms of translocal resources and integral EE of enterprises in the CWS. Additionally, the CWS generates social impacts on the local community through social enterprises. This paper contributes to ecosystem literature by introducing an actor-centric perspective and giving new insights into social entrepreneurship and the transformative power of CWSs as brokers.

Targeted and untargeted screening of a plant extract library established from raw materials originating from Upper Austria

Plant extracts rich in phytochemicals are known for their health benefits. Plant extract library from edible plants obtained from the region of Upper Austria was prepared. Food grade extraction procedures were applied, and relevant physico-chemical parameters measured. A focus on polyphenolic compounds revealed a significant correlation between the total phenolic content (measured by a colorimetric assay) and the cumulated concentration of main individual polyphenols (measured by HPLC-DAD), demonstrating the comparability of these parameters. Targeted screening was performed by HPLC-FLD and −MS for the presence of phytomelatonin. 20 extracts were identified with concentrations of up to 1.4 µg/mL of this phytochemical, which attracts much attention from the food industry. Finally, chemometric methods were employed to cluster extracts based on their phenolic compound profile. This approach allows for an informed preselection of extracts without the need for comprehensive chemical analysis.

Comparison of the Curricula of the Bachelor´s Degree in Teaching at Austrian University Colleges of Teacher Education

The Bachelor's Degree in Teaching Qualification is a study to obtain a teaching qualification in secondary vocational education. It is a Bachelor of Education (abbrev. BEd) has a length of four semesters. At all four university colleges, where this degree can be acquired, it is organized as part-time study on Fridays and Saturdays. It also includes asynchronous distance learning. The students of these study teach already in parallel at a given vocational high school or college as lecturers, they have a completed university degree of 240 to 300 ECTS credits.
 The BEd can be acquired at the University Colleges of Teacher Education Upper Austria, of Styria, of Vienna and of Tyrol. These University Colleges are part of alliances, “Verbünde”, according to Austrian law, where two or more University Colleges are combined (geographically) to teach the same curriculum. Here the curricula of these BEd studies will be compared. The goals of the studies, the qualifications achieved by completing the studies, and the Study Entry and Orientation phase will be looked at. The differences are in the courses for the STEOP, the Pedagogical-Practical Studies PPS and the length and content of the Bachelor thesis.

The type-section of the Gutenstein Formation at Gutenstein revisited (Anisian, Northern Calcareous Alps, Lower Austria): Lithostratigraphy, biostratigraphy and regional overview

Abstract New biostratigraphic data derived from the stratotype of the Gutenstein Formation at the village Gutenstein (Lower Austria) help to solve some long-standing problems about the stratigraphy of the Anisian stage within the eastern part of the Northern Calcareous Alps. At Gutenstein, the lower lithostratigraphic boundary of the Anisian Gutenstein Formation to the underlying lower Anisian Reichenhall Formation is defined, assuming a normal stratigraphic contact of the Reichenhall Formation to the underlying Werfen Formation and to the overlying Gutenstein Formation. Microfacial data confirm the sedimentary origin of the rauwackes of the Reichenhall Formation. A detailed lithostratigraphic and facies-oriented definition of the Gutenstein Formation includes prevailing thin and planar-bedded, black colored, sometimes fine-bedded limestone (rarely dolostone) and radiolarian (calcispheres) bearing, black colored mud- to wackestone, mostly containing some fine crinoid debris. Upsection, a quick change to an upper (Pelsonian) member of the Gutenstein Formation with nodular bedding planes and brachiopod-, crinoid-, conodont- and ammonite accumulations is presented. The general depositional environment of the Gutenstein Formation is interpreted as a dysoxic outer carbonate ramp deposit, with a shallowing upward trend to rather thick-bedded mid- and inner carbonate ramp settings of the Annaberg- and Steinalm formations. The approximate interval of the Anisian/Ladinian boundary within the type-section of Gutenstein is determined with help of new fossil findings such as dasycladalean green-algae. Based on distinct lithological differences on a regional scale, which occur in thick basinal stratigraphic successions within the Gutenstein Formation like at Großreifling (Styria, Bajuvaric Nappe System), at Innerfahrafeld (elevation Fuchsriegel, Lower Austria) and on mount Kasberg at Grünau (Upper Austria, Tirolic Nappe System), a subdivision of the Gutenstein Formation into a lower Gutenstein Member, and an upper Kasberg Member (= Upper Gutenstein Formation), is proposed herein. The lower member corresponds to the black, thin- and planar-bedded interval, whereas the Kasberg Member is characterized by nodular bedding planes, greater bed thicknesses and higher fossil content.

Maps of Quaternary sediments and features in Austria and neighbouring countries at the scales of 1:500 000 and 1:1 500 000

Abstract Today’s landscape and morphology of Austria is markedly affected by erosional and sedimentary processes active during the Quaternary. Particularly, large glaciers have shaped the landscape of the Eastern Alps. The presented maps at the scales of 1:500 000 and 1:1 500 000 aim to visualise areas, where deposition or erosion in different stages of the Quaternary prevailed. The maps (free download available) were generated with ArcGIS software using available map sheets at larger scales (1:50 000, 1:200 000). No additional field work has been conducted. The most obvious observation is that an extensive cover of Quaternary sediments predominantly occurs in the northern Alpine foreland, especially outside of Austria. The maps show that large glacier tongues of the Middle to Late Pleistocene glaciations (Günz, Mindel, Riss and Würm) existed in the northern and southeastern alpine foreland. In the east, hardly any signs of glacial coverage are visible due to later fluvial cannibalisation of features partly deposited in narrow valleys. Bordering terminal moraines, extensive, terraced fluvial deposits occur within and around the Alps showing that river courses partly changed during the Pleistocene. Aeolian sediments often accompany these sediments, but also cover huge areas in the Vienna and Tulln Basin and the Little Hungarian plain. The distribution of large rockslide events shows that they mainly formed in glacially covered areas as a result of rock destabilisation after glacier retreat. Additionally, the map shows that the alpine foreland is subject of inhomogeneous uplift since the Neogene. For example, between Salzburg and Munich, wide areas are covered by Pleistocene deposits, whereas to the west of Munich and in Upper Austria, recent rivers incised deeper into Neogene sediments.

Service time window selection for attended home deliveries: a case study for urban and rural areas

Attended home deliveries are one of the most challenging logistics services with different customer expectations and challenges in urban and rural areas. For different demand densities, retailers must strike a balance between providing excellent customer service and optimizing routing efficiency. While customers often expect delivery promises with narrow time windows, research has demonstrated that longer time windows can increase the flexibility and the ability to accept more customers. However, it is not clear how different demand densities impact flexibility and customer acceptance. To serve as many customers as possible with excellent service quality, this paper reviews and expands on ideas for offering short and long time windows in a flexible manner in urban and rural areas. This study proposes different methods for providing customers with time windows of different lengths and investigates their performance based on a case study in Vienna and Upper Austria.

A criterion and incremental design construction for simultaneous kriging predictions

In this paper, we further investigate the problem of selecting a set of design points for universal kriging, which is a widely used technique for spatial data analysis. Our goal is to select the design points in order to make simultaneous predictions of the random variable of interest at a finite number of unsampled locations with maximum precision. Specifically, we consider as response a correlated random field given by a linear model with an unknown parameter vector and a spatial error correlation structure. We propose a new design criterion that aims at simultaneously minimizing the variation of the prediction errors at various points. We also present various efficient techniques for incrementally building designs for that criterion scaling well for high dimensions. Thus the method is particularly suitable for big data applications in areas of spatial data analysis such as mining, hydrogeology, natural resource monitoring, and environmental sciences or equivalently for any computer simulation experiments. We have demonstrated the effectiveness of the proposed designs through two illustrative examples: one by simulation and another based on real data from Upper Austria.

Comparison of requirements of graduates entering employment in Vysočina Region and region Upper Austria

PurposeCurrently, owing to the influence of rapid globalisation, the issue of international and cross-cultural implementation of cross-cultural relationships is being widely discussed. This is also related to the readiness of graduates for international cooperation. The objective of this qualitative study is to identify and compare the requirements of company representatives from the Czech Republic – the Vysocina Region and Austria (Region Upper Austria) regarding the readiness of graduates to entering the workforce and the intercultural differences between the relevant regions.Design/methodology/approachA total of 20 Czech and Austrian companies from the relevant regions participated in the research. The results were obtained through in-depth guided interviews and a comparative method.FindingsThe qualitative study has theoretical implications in the context of new findings in the field of research. It contributes to the knowledge relating to the preparation of graduates for entering the workforce, and in the context of intercultural development, it extends this knowledge with the identified weaknesses of the mentioned preparation at the level of Czech or Austrian education.Originality/valueThe most effective and probable approach to enhance the development of cross-cultural competences in particular appears to be the integration of new techniques and content of education in the form of new subjects in cooperation with academics and practitioners from the particular country. Collaboration with these experts can build students' knowledge and skills from an intercultural environment to the highest degree possible.

Occurrence of Thelazia callipaeda and its vector Phortica variegata in Austria and South Tyrol, Italy, and a global comparison by phylogenetic network analysis.

The zoonotic nematode Thelazia callipaeda infects the eyes of domestic and wild animals and uses canids as primary hosts. It was originally described in Asia, but in the last 20 years it has been reported in many European countries, where it is mainly transmitted by the drosophilid fruit fly Phortica variegata. We report the autochthonous occurrence of T.callipaeda and its vector P.variegata in Austria. Nematodes were collected from clinical cases and fruit flies were caught using traps, netting, and from the conjunctival sac of one dog. Fruit flies and nematodes were morphologically identified and a section of the mitochondrial cytochrome c oxidase subunit I gene (COI) was analysed. A DNA haplotype network was calculated to visualize the relation of the obtained COIsequences to published sequences. Additionally, Phortica spp. were screened for the presence of DNA of T.callipaeda by polymerase chain reaction. Thelazia callipaeda and P.variegata were identified in Burgenland, Lower Austria, and Styria. Thelaziacallipaeda was also documented in Vienna and P.variegata in Upper Austria and South Tyrol, Italy. All T.callipaeda corresponded to haplotype 1. Twenty-two different haplotypes of P.variegata were identified in the fruit flies. One sequence was distinctly different from those of Phorticavariegata and was more closely related to those of Phortica chi and Phortica okadai. Thelazia callipaeda could not be detected in any of the Phortica specimens.

Umfahrung Weyer – Tunnelbau im Lockergestein unter Bebauung

AbstractThe small town of Weyer is located in Upper Austria on the B121 Weyerer Straße. The B121 leads through the historic market square of Weyer, which is characterised by confusing bottlenecks that can only be passed in one lane. For decades, these bottlenecks have caused congestion, mainly due to heavy traffic. For residents, the burden of air pollution and noise is high. The roads department of the Upper Austrian Government has been planning the construction of a bypass for many years. Construction finally started in the summer of 2022. The Weyer bypass construction lot is 1.2 km long and includes the construction of two NATM tunnels, a vertical escape shaft, a bridge over the river Dürnbach, two roundabouts, and one traffic junction. The tunnel construction works are carried out in urban areas, in loose material with little overburden and partly under existing buildings. These boundary conditions make the project a challenge for all involved at every stage.
