Recognizing actions of humans, reliably inferring their meaning and being able to potentially exchange mutual social information are core challenges for autonomous systems when they directly share the same space with humans. Today’s technical perception solutions have been developed and tested mostly on standard vision benchmark datasets where manual labeling of sensory ground truth is a tedious but necessary task. Furthermore, rarely occurring human activities are underrepresented in such data leading to algorithms not recognizing such activities. For this purpose, we introduce a modular simulation framework which offers to train and validate algorithms on various environmental conditions. For this paper we created a dataset, containing rare human activities in urban areas, on which a current state of the art algorithm for pose estimation fails and demonstrate how to train such rare poses with simulated data only.
Using measurement and simulation for understanding distributed development processes in the Cloud
(2017)
Organizations increasingly develop software in a distributed manner. The Cloud provides an environment to create and maintain software-based products and services. Currently, it is widely unknown which software processes are suited for Cloud-based development and what their effects in specific contexts are. This paper presents a process simulation to study distributed development in the Cloud. We contribute a simulation model, which helps analyzing different project parameters and their impact on projects carried out in the Cloud. The simulator helps reproducing activities, developers, issues and events in the project, and it generates statistics, e.g., on throughput, total time, and lead and cycle time. The aim of this simulation model is thus to analyze the tradeoffs regarding throughput, total time, project size, and team size. Furthermore, the modified simulation model aims to help project managers select the most suitable planning alternative. Based on observed projects in Finland and Spain, we simulated a distributed project using artificial and real data. Particularly, we studied the variables project size, team size, throughput, and total project duration. A comparison of the real project data with the results obtained from the simulation shows the simulation producing results close to the real data, and we could successfully replicate a distributed software project. By improving the understanding of distributed development processes, our simulation model thus supports project managers in their decision-making.
Scroll-activated animations eröffnen Webentwicklern neue Möglichkeiten der Interaktion und Präsentation von Inhalten. Durch die Animation von Bildern, Texten und weiteren Elementen einer Website soll der Nutzer durch die neue Darstellungsart positiv überrascht werden. Ziel ist es, dem Nutzer die Inhalte interessanter und möglichst gezielt zu vermitteln. Es stellt sich jedoch die Frage, ob die dadurch gesteigerte User Experience zulasten der Usability erfolgt. Unter Umständen führen die Animationen beim Nutzer zwar zu einem Aha-Effekt, setzen jedoch die Benutzerfreundlichkeit herab. Aus diesem Grund geht die Arbeit auf den Aspekt der Usability und User Experience dieser Animationen ein und untersucht den tatsächlichen Mehrwert des Einsatzes von Scroll-Animationen mithilfe von Webanalysetools. Durch den Vergleich mit einer inhaltlich identischen Seite sollen die oben genannten Effekte untersucht werden. Zusätzlich sollen die Ergebnisse nach Gerätetypen aufgeschlüsselt werden, um mögliche Unterschiede aufzudecken.
Im präventiven Krisenmanagement geht es um die frühzeitige Erkennung von möglichen, unvorhersehbaren Ereignissen. Hierzu zählen beispielhaft Busunfälle, einstürzende Gebäude und ähnliche Großschadensereignisse. Krisen treten meist unerwartet auf und neigen oftmals aufgrund der knapp bemessenen Handlungszeit zu Fehlentscheidungen. Um dies zu verhindern, dient das präventive Krisenmanagement dazu, sämtliche auftretende Ereignisse mittels einer Simulation zuvor durchzuspielen, um im Falle einer reellen Krise die notwendigen Schritte bestmöglich einzuleiten. Um Simulationen für das Krisenmanagement zu präzisieren und die Ergebnisse effektiv und vereinfacht zu veranschaulichen, ist es notwendig, eine Vorauswahl an vorhandenen Szenarien für Vergleiche heraussuchen zu können. Diese Arbeit entstand im Rahmen des FP-7 EU Projekts CRISMA (Crisis Management) [1] und dient zur Evaluation eines Konzepts zur Vorauswahl geeigneter Szenarien, welche in früheren Simulationen entstanden.
Autismus-Spektrum-Störungen (ASD) bei Kindern werden häufig zu spät diagnostiziert und die Begleitung der chronischen Krankheit gestaltet sich schwierig. Der vorgestellte Ansatz erlaubt die Behandlung der Kinder in dem bekannten häuslichen Umfeld und versucht die Beziehungen zwischen Schlaf und Verhalten herauszuarbeiten. Die gewonnenen Erkenntnisse sollen die Lebensqualität der Patienten verbessern und den Eltern Hilfestellung geben. Die notwendige infrastrukturelle Unterstützung wird durch medizinisches Fachpersonal geleistet, das auf einen web-basierten Service zurückgreifen kann, der sämtliche Prozesse (Diagnostik, Datenerfassung, -aufzeichnung und Training etc.) begleitet. Die anonymisierten Daten werden in einem Diagnosesystem zentral abgelegt und können so für zukünftige Behandlungsstrategien nutzbar sein. Die umfassende Lösung setzt auf zentrale Elemente von Smart-Homes und AAL auf.
Am Körper getragenen Geräte, sog. Wearables, kommunizieren in der Regel über Bluetooth-Low-Energy (BLE) mit dem Smartphone. Viele Anwendungen, insbesondere im Bereich Gesundheit und AAL, basieren auf der Zusammenarbeit von Wearables mit SmartHome-Geräten. Diese Arbeit präsentiert die Definition und Implementierung von einem neuen BLE Profil für EKG, das Streaming der Signal zum SmartPhone und die Möglichkeit, mehrere solcher Biosignale parallel zu streamen, besitzt. Die Datenarchitektur der App erlaubt eine konfigurierbare Synchronisation der Signal mit dem SmartHome.
Enterprises and societies currently face essential challenges, and digital transformation can contribute to their resolution. Enterprise architecture (EA) is useful for promoting digital transformation in global companies and information societies covering ecosystem partners. The advancement of new business models can be promoted with digital platforms and architectures for Industry 4.0 and Society 5.0. Therefore, products from the sector of healthcare, manufacturing and energy, etc. can increase in value. The adaptive integrated digital architecture framework (AIDAF) for Industry 4.0 and the design thinking approach is expected to promote and implement the digital platforms and digital products for healthcare, manufacturing and energy communities more efficiently. In this paper, we propose various cases of digital transformation where digital platforms and products are designed and evaluated for digital IT, digital manufacturing and digital healthcare with Industry 4.0 and Society 5.0. The vision of AIDAF applications to perform digital transformation in global companies is explained and referenced, extended toward the digitalized ecosystems such as Society 5.0 and Industry 4.0.
Enterprises and societies currently face crucial challenges, while Society 5.0 can contribute to a supersmart society, especially for manufacturing and healthcare, and Industry 4.0 becomes important in the global manufacturing industry. Smart energy digital platforms are architected to manage energy supply efficiently. Furthermore, the above digital platforms are expected to collect various kinds of data and analyze Big Data for the trends in the sharing economy in ecosystems. The adaptive integrated digital architecture framework (AIDAF) for Design Thinking Approach with Risk Management is expected to make an alignment with digital IT strategy. In this paper, we propose that various energy management systems and related digital platforms are designed and implemented in an alignment to digital IT strategy for sharing economy toward Society 5.0, with the AIDAF framework for Design Thinking Approach with Risk Management. The vision of AIDAF applications to enable sharing economy and digital platforms is explained and extended in the context of Society 5.0. In addition, challenges and future activities for this area are discussed that cover the directions of smart energy for Society 5.0.
Enterprises and societies currently face crucial challenges, while Industry 4.0 becomes important in the global manufacturing industry all the more. Industry 4.0 offers a range of opportunities for companies to increase the flexibility and efficiency of production processes. The development of new business models can be promoted with digital platforms and architectures for Industry 4.0. Therefore, products from the healthcare sector can increase in value. The adaptive integrated digital architecture framework (AIDAF) for Industry 4.0 is expected to promote and implement the digital platforms and robotics for healthcare and medical communities efficiently. In this paper, we propose that various digital platforms and robotics are designed and evaluated for digital healthcare as for manufacturing industry with Industry 4.0. We argue that the design of an open healthcare platform “Open Healthcare Platform 2030 - OHP2030” for medical product design and robotics can be developed with AIDAF. The vision of AIDAF applications to enable Industry 4.0 in the OHP2030 research initiative is explained and referenced, extended in the context of Society 5.0.
Enterprises and information societies confront crucial challenges currently, while Industry 4.0 becomes important in the global manufacturing industry and Society 5.0 should contribute to a supersmart society, especially for healthcare. Physical activity monitoring digital platforms are architected to improve the healthcare status of patients with diabetes and other lifestyle-related diseases. Furthermore, digital platforms are expected to generate profits for health technology companies and help control costs in the healthcare ecosystem. However, current digital enterprise architecture approaches are not well-established, and the potentials have not yet been realized. Design thinking approach and agile software development methodologies can overcome these limitations, beginning with proof of concept and pilot projects and then scaling to the production environment. In this paper, we describe how that the adaptive integrated digital architecture framework (AIDAF) for Design Thinking approach is proposed and verified in a case of a university hospital in the Americas. In addition, challenges and future activities for this area are discussed that cover the directions for Society 5.0.
