Trotz hoher Prävalenz von Kopfschmerzerkrankungen und bedeutender Beeinträchtigung vieler Betroffener ist die Versorgung von Menschen mit häufigen Kopfschmerzen in Deutschland unzureichend. Zur Verbesserung der Versorgung und Erhebung von Daten zur Versorgungs- und Kopfschmerzforschung richtet die Deutsche Migräne- und Kopfschmerzgesellschaft (DMKG) e. V. ein deutschlandweites Kopfschmerzregister ein. Vor der Erstvorstellung und vor jeder Wiedervorstellung bei einem am Kopfschmerzregister teilnehmenden Arzt werden die Patienten gebeten, Daten zu ihren Kopfschmerzen, aktuellen und bisherigen Behandlungsversuchen sowie Begleiterkrankungen über ein Patientenportal einzugeben. Ein Kopfschmerzkalender wird über die DMKG-App bereitgestellt. Während der Vorstellung stehen dem Arzt die vorab erhobenen Patientendaten zur Unterstützung einer strukturierten Anamnese und Behandlungsplanung zur Verfügung; sie können ergänzt, geändert oder bestätigt werden. In anonymisierter Form werden die Daten in eine Auswertungsdatenbank überführt, die für wissenschaftliche Auswertungen zur Versorgungs- und allgemeinen Kopfschmerzforschung genutzt werden kann. Das Kopfschmerzregister wird voraussichtlich im 4. Quartal 2019 starten.

Gasification of biomass is known for its valuable capabilities in small, flexible and decentral applications for cogeneration of power and heat. However, the produced raw syngas contains a variety of unwanted higher hydrocarbons such as aromatics and tar compounds in varying amounts adversely for a stable operation of such gasification plants. This cooperative project between the University of Bayreuth (CVT, ZET), the UAS Hof and the company WS Wärmeprozesstechnik aims to develop a new downdraft biomass gasification technology. Herein, the main innovation is the use of the charcoal directly formed by biomass pyrolysis in the gasifier as an adsorption agent for the unwanted tar components in a subsequent cooled adsorption section. The technology with regard to the formation of a suitable adsorption agent is in analogy to the common production of activated carbon by treatment of charcoal with CO2 and/or H2O at temperatures of around 900°C to achieve a high surface area. But here, the activated carbon is directly produced within the downdraft gasification reactor by the controlled, i.e. uncompleted conversion of the biomass coke formed by pyrolysis. Hence, the coke is only partly gasified to syngas and the residual amount is used as activated carbon for tar adsorption. By subsequent cooling of the activated charcoal and the raw product gas to a temperature of 70°C suitable for adsorption, the tar components are almost completely adsorbed and removed from the syngas to make it usable for cogeneration without further treatment. To gain all relevant informations about the main parameters of the overall process (char formation/conversion, formation and subsequent adsorption of tar), respective measurements were conducted in order to finally create a reliable numerical model of the process. The respective results, e.g. regarding kinetic data of char conversion in the gasification unit and adsorption data achieved with naphthalene as a model substance for the tar, will be presented.

In this work, honeypots were set up on several public cloud infrastructures of Amazon, Microsoft and Google located in different regions around the world, including North America, Asia and Europe. The honeypots, simulating different popular services like SSH and VNC, were used to collect data over a period of two month, resulting in over 170 million log entries. Further analysis of the log entries regarding attack patterns and geographic characteristics are presented in this paper. For example, the attacks originated from 216 countries involving 268,614 unique IPs, dominated by China with a share of 25.83%.

Given the importance of an early anomaly detection, Intrusion Detection Systems (IDSs) are introduced in Supervisory Control And Data Acquisition (SCADA). Agents or probes form the cornerstone of any IDS by capturing network packets and extracting relevant information. However, IDSs are facing unprecedented challenges due to the escalation in the number, scale and diversity of attacks. Software-Defined Network (SDN) then comes into play and can provide the required flexibility and scalability. Building on that, we introduce Traffic Agent Controllers (TACs) that monitor SDN-enabled switches via Open-Flow. By using lightweight statistical metrics such as Kullback-Leibler Divergence (KLD), we are able to detect the slightest anomalies, such as stealth port scans, even in the presence of background traffic. The obtained metrics can also be used to locate the anomalies with precision over 90% inside a hierarchical network topology.

The main objectives of the Intelligent Transportation Systems (ITS) vision is to improve road safety, traffic management, and mobility by enabling cooperative communication among participants. This vision requires the knowledge of the current state of the road traffic, which can be obtained by collecting Floating Car Data (FCD) information using Dedicated Short-Range Communication (DSRC) based on the IEEE 802.11p standard. Most of the existing FCD collection protocols have been evaluated via simulations and mathematical models, while the real-world implications have not been thoroughly investigated. This paper presents an open-source implementation of two state-of-the-art FCD collection algorithms, namely BASELINE and DISCOVER. These algorithms are implemented in an open-source vehicular prototyping platform and validated in a real-world experimental setup.

It is our great pleasure to welcome you to the 30th Anniversary ACM Conference on Hypertext and Social Media at Hof University, Germany, on September 17-20, 2019. The ACM Hypertext conference is a premium venue for high quality peer-reviewed research on hypertext theory, systems and applications. It is concerned with all aspects of modern hypertext research including social media, semantic web, dynamic and computed hypertext and hypermedia as well as narrative systems and applications. The theme of Hypertext 2019 is "HYPERTEXT - TEAR DOWN THE WALL". This motto of the 30th ACM Hypertext conference goes hand in hand with the 30th anniversary of the fall of the Berlin Wall. Inspired by the historical events in Germany, Hypertext 2019 aims at reunifying different hypertext research directions and communities. Therefore, apart from the regular research tracks, Hypertext 2019 will feature a research track on 30 Years of Hypertext as well as an exhibition/creative track. 2019 will also be the 30th anniversary of the WWW. It is a perfect time to join in, reflect our common roots, and discuss how we can jointly address our current and future challenges. The conference will take place at the Institute of Information Systems (iisys) at Hof University, Germany. Hof lies midway between Frankfurt and Prague, Munich and Berlin and is very close to the former German-German border, in particular to the village of Modlareuth, called "little Berlin", which used to be divided by a wall. After exactly 20 years, Hypertext 2019 will take place in Germany again for the 2nd time. Hypertext 2019 is co-locating with the ACM Document Engineering Conference (DocEng'19) organized in Berlin, Germany, between September 23-16.
