Die Dozenten der Informatik-Institute der Technischen Universität
Braunschweig machen auf folgenden Vortrag der GI Regionalgruppe
Braunschweig aufmerksam:
Markus Abel und André von Hof, Gobas GmbH und FHAIN DATA CONCEPT GmbH:
GI-Vortrag: more design - less code – Softwaremetriken als
Designunterstützung in der SAP® Welt!
Beginn: 25.09.2014, 19:00 Uhr
Ort: Haus der Wissenschaft, Raum Veolia, Pockelsstraße 11
Webseite: http://www.lineas.de/gi-bs/
Kontakt: Anja Schaar-Goldapp, Sprecherin der GI Regionalgruppe BS
Gegenstand dieses Vortrags ist die Übertragung modellgetriebener
Entwicklungsansätze in die SAP-Umgebung und die daraus resultierenden
Auswirkungen. Komplexität ist eine der großen Herausforderungen von
Softwaresystemen und ihrer Entwicklung. Der komplexe und vielschichtige
Entwicklungsprozess in der SAP® Welt führt oft zu Problemen mit
Releaseterminen und Budget. Modellgetriebene Softwareentwicklung betont
die zentrale Rolle formaler Modelle und setzt auf ihre automatische
Synchronisation in verschiedenen Entwicklungsstadien. So soll die
Komplexität durchbrochen und die Entwicklungszyklen verkürzt werden.

Skill-based human-robot interface for instructing industrial tasks

The talk will be based on the research at Aalborg University, which
focuses on developing interactive manipulation systems for manufacturing
tasks such as part feeding and assembly. The concern with such systems
is that they should be programmable easily and flexibly by the laymen
at the factory floor, and they should respond to the fast changing
tasks and conditions. To this end we have developed the concept of
"task-level-programming" that integrates pre-defined "skill" modules
of the robot with kinesthetic teaching by the operators. The skill
modules have the features of being easily programmable and being the
constitutive elements of complex manipulation tasks performed by robot,
all to be programmed by a layman worker. Different versions of the
system are tested on a number of different factory floors for various
manufacturing tasks. The extensive experience with actual factory floor
applications does not only demonstrate the success of the concept but also
pinpoints challenges, bottlenecks, and future directions for application
of assistive robotics in industrial settings.

Due to cost-efficiency and less hands-on management, big data owners
are outsourcing their data to the cloud, which can provide access to the
data as a service. However, by outsourcing their data to the cloud, the
data owners lose control over their data, as the cloud provider becomes a
third party service provider. At first, encrypting the data by the owner
and then exporting it to the cloud seems to be a good approach. However,
there is a potential efficiency problem with the outsourced encrypted data
when the data owner revokes some of the users’ access privileges. An
existing solution to this problem is based on symmetric key encryption
scheme but it is not secure when a revoked user rejoins the system with
different access privileges to the same data record. In this talk, I
will discuss an efficient and Secure Data Sharing (SDS) framework using a
combination of homomorphic encryption and proxy re-encryption schemes that
prevents the leakage of unauthorized data when a revoked user rejoins
the system. I will also discuss the modifications to our underlying
SDS framework and present a new solution based on the data distribution
technique to prevent the information leakage in the case of collusion
between a revoked user and the cloud service provider. A comparison of the
proposed solution with existing methods will be discussed. Furthermore,
I will outline how the existing work can be utilized in our proposed
framework to support secure query processing for big data analytics. I
will provide a detailed security as well as experimental analysis of
the proposed framework on Amazon EC2 and highlight its practical use.
Biography: Sanjay Kumar Madria received his Ph.D. in Computer Science
from Indian Institute of Technology, Delhi, India in 1995. He is a full
professor in the Department of Computer Science at the Missouri University
of Science and Technology (formerly, University of Missouri-Rolla, USA)
and site director, NSF I/UCRC center on Net-Centric Software Systems. He
has published over 200 Journal and conference papers in the areas of
mobile data management, Sensor computing, and cyber security and trust
management. He won three best papers awards including IEEE MDM 2011 and
