Im Bereich des Architekturmanagements existiert eine Vielzahl von Architekturmodellen und branchenspezifischen Ausprägungen. In diesem Beitrag stellen wir einen Ansatz vor, mit dem die IT-Architektur der Finanzfunktion in einem Cloudumfeld dargestellt werden kann.

Distributed heuristics have shown promising results in handling difficult optimization and coordination tasks in smart grids, which often have to deal with large numbers of components, distributed information and real time constraints. Some of these heuristics are distributed on an algorithmic level. This means that the ...

Due to the increasingly unmanageable number of art-historical inventories made available in digital form, methods that computationally arrange larger amounts of objects are becoming more important. The category of similarity, which is fundamental in all areas of art-historical description, gains new relevance in this ...

At many charging stations, the charging process of battery electric vehicles (BEV) takes significantly more time than refilling a gas tank. In combination with the lack of charging stations, this results in more planning effort for drivers who have to find a free charging station. In addition, charging draws a significant ...

Web archive analytics is the exploitation of publicly accessible web pages and their evolution for research purposes—to the extent organizationally possible for researchers. In order to better understand the complexity of this task, the first part of this paper puts the entirety of the world's captured, created, and ...

The increase in interconnected devices in electrical power systems raises the attack surface of a network and therefore the system connected within the network. Cyber-attacks can lead to power cut of an individual system or multiple systems required in the power generation stage and critical in normal operation of the ...

According to the process acceptance theory, the acceptance of processes can have an influence on their correct execution. If deviations and manipulations of processes of any kind are to be excluded, it is necessary to understand which factors lead to a change in acceptance. In the present paper, a large scale experimental ...

Security for the mostly constrained devices forming the IoT is an active field of research. In this paper, we propose two CoAP Options, HMAC1/HMAC2 and Crypt1/Crypt2 complementing our previous work on Lightweight Capability Based Access Control (LCap). This results in a lightweight, flexible, and complete solution for ...

Nach wie vor sind große Unternehmen Vorreiter der Digitalisierung. Doch der Mittelstand erschließt in immer stärkerem Maße seine digitalen Potentiale und holt auf. So planten im Jahr 2019 38,8% der in einer Studie der KfW befragten kleinen Unternehmen mindestens zwei Digitalisierungsvorhaben in den kommenden zwei Jahren ...

Public Displays werden bereits in vielen Städten eingesetzt, zum Beispiel als elektronische Fahrplanauskünfte, Infoboards in Innenstädten oder Selbst-Check-In Stehlen an Flughäfen. Wenige dieser Public Displays bieten einen Verbindungsaufbau zum eigenen Smartphone an. Im Fokus steht die Übertragung der eigenen Strecke ...
