Knowledge in Computer Science (CS) is essential, and companies have increased their demands for CS professionals. Despite this, many jobs remain unfilled. Furthermore, employees with computational thinking (CT) skills are required, even if they are not actual technicians. Moreover, the gender disparity in technology related fields is a serious problem. Even if companies want to hire women in technology, the number of women who enter these fields is remarkably low. In high schools, most teenagers acquire only low-level skills in CS. Thus, they may never understand the fundamental concepts of CS, have unrealistic expectations or preconceptions, and are influenced by stereotype-based expectations. Consequently, many teenagers exclude computing as a career path. In this research study, we present two promising concepts to overcome these challenges. First, we consider alternative paths to enter the field of CS. In 2018, a voluntary lecture "Design your own app" at the university of Graz for students of all degree programs was introduced. In total, 202 students participated. We applied a Game Development-Based Learning (GDBL) approach with the visual coding tool Pocket Code, a mobile app developed at Graz university of technology. The students were supposed to create simple games directly on smartphones. The course received positive evaluations and led to our second concept;In January 2019, we started to design a MOOC (Massive Open Online Course) with the title "Get FIT in Computer Science". The MOOC will be launched in August 2019 on the platform *** and will provide a general introduction to the field of CS. For exercises and the final submission, the students need to apply game design strategies by using Pocket Code. The MOOC has several target groups. First, this course can be used to encourage young women who have little to no previous knowledge in CS. Second, it should help all teenagers to get a more realistic picture of CS to its basic concepts. Third, teache

Matchmaking and cooperation are interactions widely available within internet-based platforms. However, to start using such functionality, one must first become a member of the platform. In an effort to push matchmaking and cooperation into the protocol stack of the Web, we demonstrate how an existing taxi service is integrated with a decentralized Web based infrastructure, the Web of Needs (WoN), using a chatbot that can be programmed declaratively to enter into certain types of agreements with users. The bot mediates between an existing Web service and users of the RDF-based WoN network. © 2018 CEUR-WS. All Rights Reserved.

Due to its high lethality amongst the elderly, the safety of nursing homes has been of central importance during the COVID-19 pandemic. With test procedures becoming available at scale, such as antigen or RT-LAMP tests, and increasing availability of vaccinations, nursing homes might be able to safely relax prohibitory measures while controlling the spread of infections (meaning an average of one or less secondary infections per index case). Here, we develop a detailed agent-based epidemiological model for the spread of SARS-CoV-2 in nursing homes to identify optimal prevention strategies. The model is microscopically calibrated to high-resolution data from nursing homes in Austria, including detailed social contact networks and information on past outbreaks. We find that the effectiveness of mitigation testing depends critically on the timespan between test and test result, the detection threshold of the viral load for the test to give a positive result, and the screening frequencies of residents and employees. Under realistic conditions and in absence of an effective vaccine, we find that preventive screening of employees only might be sufficient to control outbreaks in nursing homes, provided that turnover times and detection thresholds of the tests are low enough. If vaccines that are moderately effective against infection and transmission are available, control is achieved if 80% or more of the inhabitants are vaccinated, even if no preventive testing is in place and residents are allowed to have visitors. Since these results strongly depend on vaccine efficacy against infection, retention of testing infrastructures, regular voluntary screening and sequencing of virus genomes is advised to enable early identification of new variants of concern. © 2020, CC BY-NC-SA.

This work presents a diagnosis method for detecting track circuits failures on a railway traffic line equipped with an Automatic Block Signalling installation. The diagnosis method uses the installation's electrical schemas, based on which a series of diagnosis charts have been created. Further, the diagnosis charts were used to develop a software package, CDCBla, which substantially contributes to reducing the diagnosis time and human error during failure remedies. The proposed method can also be used as a training package for the maintenance staff. Since the diagnosis method here does not need signal or measurement inputs, using it does not necessitate additional IT knowledge and can be deployed on a mobile computing device (tablet, smart phone). © Published under licence by IOP Publishing Ltd.

This work presents a diagnosis method for railway traffic security installations. More specifically, the authors present a series of diagnosis charts for passing signals on a railway block equipped with an automatic block signaling installation. These charts are based on the exploitation electric schemes, and are subsequently used to develop a diagnosis software package. The thus developed software package contributes substantially to a reduction of failure detection and remedy for these types of installation faults. The use of the software package eliminates making wrong decisions in the fault detection process, decisions that may result in longer remedy times and, sometimes, to railway traffic events. © Published under licence by IOP Publishing Ltd.

IEEE International Conference on Image Processing

作者： Markus Horhan Horst Eidenberger Vienna University of Technology Institute of Software Technology and Interactive System Vienna Austria

In this paper, we propose a novel approach for the domain of makeup-robust face recognition. Most face recognition schemes usually fail to generalize well on these data where there is a large difference between the training and testing sets, e.g., makeup changes. Our method focuses on the problem of determining whether face images before and after makeup refer to the same identity. The work on this fundamental research topic benefits various real-world applications, for example automated passport control, security in general, and surveillance. Experiments show that our method is highly effective in comparison to state-of-the-art methods.

We present a multi-modal Deep Neural Network (DNN) approach for bird song identification. The presented approach takes both audio samples and metadata as input. The audio is fed into a Convolutional Neural Network (CNN) using four convolutional layers. The additionally provided metadata is processed using fully connected layers. The flattened convolutional layers and the fully connected layer of the metadata are joined and fed into a fully connected layer. The resulting architecture achieved 2., 3. and 4. rank in the BirdCLEF2017 task in various training configurations. Copyright © 2018, The Authors. All rights reserved.

This paper presents a novel method for the discovery of new analytical filters suitable for filtering of noise in Monte Carlo rendering. Our method utilizes genetic programming to evolve the set of analytical filtering expressions with the goal to minimize image error in training scenes. We show that genetic programming is capable of learning new filtering expressions with quality comparable to state of the art noise filters in Monte Carlo rendering. Additionally, the analytical nature of the resulting expressions enables the run-times one order of magnitude faster than compared state of the art methods. Finally, we present a new analytical filter discovered by our method which is suitable for filtering of Monte Carlo noise in diffuse scenes.

Procedia CIRP 2018年 67卷 128-133页

The emergence of cyber physical systems in the manufacturing domain creates new requirements for shop floor devices. Due to their diverse structure, buildup a seamless communication is one major challenge. In recent years, several communication standards, e.g., OPC-UA, tried to tackle this issue. Until now, they have not fully developed their potential, because of inherent implementation complexity and specific formats, although well-known modeling standards such as UML exist. The presented approach aims to overcome this complexity by enabling an automatic transformation from UML class diagrams to OPC-UA information models using ATL and by extending UML to guarantee information preserving transformations.

Computer Vision Applications in Sports 2017

作者： Vorstandlechner, Mario Gelautz, Margrit Putz, Christoph Institute of Software Technology and Interactive Systems Vienna University of Technology Austria AFC Vienna Vikings Austria

A playbook in American Football can consist of hundreds of plays, and to learn each play and the corresponding assignments and responsibilities is a big challenge for the players. In this paper we propose a teaching tool for coaches in American Football based on computer vision and visualization techniques which eases the learning process and helps the players gain deeper knowledge of the underlying concepts. Coaches can create, manipulate and animate plays with adjustable parameters which affect the player actions in the animation. The general player behaviors and interactions between players are modeled based on expert knowledge. The final goal of the framework is to compare the theoretical concepts with their practical implementation in training and game, by using computer vision algorithms which extract spatio-temporal motion patterns from corresponding real video material. First results indicate that the software can be used effectively by coaches and the players' understanding of critical moments of the play can be increased with the animation system. © 2017, Society for Imaging Science and technology.
