Komplexe Systeme

Abstract: Ein komplexes System besteht aus miteinander verbundenen Teilen. Das System als Ganzes zeigt eine oder mehrere emer- gente Eigenschaften, welche nicht einfach aus den Eigenschaf- ten der einzelnen Teile abgeleitet werden können.

Das heißt, ein komplexes System verwehrt sich der Vereinfa- chung. Komplexe Systeme sind in vielen Bereichen wie z.B. Phy- sik (Interaktion von Teilchen), Chemie (chem. Reaktionen), Sozio- logie (Interaktion zwischen Menschen), Ökonomie (Vernetzung in der Wirtschaft) und Ökologie (Nahrungsketten) bereits allgegen- wärtig.

Durch die zunehmende Vernetzung von Komponenten in der Technik wird Wissen zu komplexen Systemen auch für die Infor- matik und Informationstechnik zunehmend bedeutender. Dazu ist es notwendig, sich eine neue Art und Weise anzueignen, um Systeme zu betrachten.

Im Rahmen diese einführenden Vortrags soll diese Grundlage an Hand einiger einfache Beispiele vermittelt werden.

Keywords: Komplexe Systeme, Vernetzung, selbstorganisierende Systeme

Haptic Communications

True immersion into a distant environment and efficient distributed collaboration require the ability to physically interact with remote objects and to literally get in touch with other people. Touching and manipulating objects remotely becomes possible if we augment traditional audiovisual communications by the haptic modality. Haptic communications is a relatively young field of research that has the potential to substantially improve human–human and human–machine interaction.

In this talk, we address perceptual coding of haptic information and the transmission of haptic data streams over resource-constrained and potentially lossy networks. In this context, we also briefly discuss the need for objective quality metrics for haptic communication. Throughout the talk, we stress the fact that haptic communications is not meant as a replacement of traditional audiovisual communications but rather as an additional dimension for telepresence that will allow us to advance in our quest for truly immersive communication.

Student Placements at EnOcean, Munich, Germany

13 MONTH PLACEMENTS FOR STUDENTS IN: ELECTRONICS, SOFTWARE, COMPUTER or MECHANICAL ENGINEERING [PDF]

These placements start July 2012 and end August 2013

Successful candidates will be based at EnOcean’s Headquarters in Oberhaching, in the south-east area of Munich. EnOcean is a young company with a culture of innovation. Across its over 10 years of operation it has demonstrated a continuing commitment to the development of young Engineers.

EnOcean is the originator of patented energy harvesting wireless technology

The company manufactures and markets maintenance-free wireless sensor solutions for use in buildings and industrial installations. EnOcean solutions are based on miniaturized energy converters, ultra-low- power electronic circuitry and reliable wireless. Combining these elements enables EnOcean and its product partners to offer sensor systems that are fundamental for energy-efficient buildings and innovative industry. Today wireless modules from EnOcean are chosen worldwide by more than 100 manufacturers to enable their system ideas for buildings and industry. Wireless components are already in use in over 200,000 buildings.

EnOcean GmbH was founded in 2001 as a spin-off from Siemens AG. The company currently employs about 60 people in Germany and the USA.

EnOcean Technology

The basic idea behind this innovative technology stems from a simple observation: where sensors capture measured values, the energy state constantly changes. When a switch is pressed, the temperature alters or the luminance level varies. All these operations generate enough energy to transmit wireless signals. Instead of batteries, EnOcean consequently uses miniaturized energy converters to supply power: linear motion converters, solar cells and thermal converters. These allow wireless operation in very different surroundings. Intelligent software stacks enable straightforward and simple integration of EnOcean technology in a large variety of user applications.

EnOcean Alliance

Companies worldwide from the building sector established an innovative control solution for sustainable building projects. The EnOcean Alliance aims to standardize and internationalize EnOcean technology, and is dedicated to creating interoperability between the products of OEM partners.

INTERNSHIPS

The selected candidates will work in the development Labs of EnOcean, but being a small company, there will also be regular involvement with marketing, sales, and manufacturing – a chance to experience the “full picture”. The year-long term of these placements allow the candidates to become deeply familiar with EnOcean technology and have a real chance to contribute something useful. As the company continues to grow, it is expected that some of our Interns will return to EnOcean as employees after their graduation.

Fastest: test case generation from Z specifications

Abstract:

Fastest is a tool that assist software engineers in generating test cases from Z specifications. It provides tool support for a method of model-based testing know as the Test Template Framework. The tool reads a Z specification written in LaTeX markup and waits for commands from the user. Users can apply testing tactics to partition the input space of Z operations thus creating testing trees. Later they can prune these trees to eliminate unsatisfiable test specifications. In a third step, a satisfiability algorithm can be run to find a test case for each leaf in a testing tree. Finally, it is possible to refine these test cases into programs to test the implementation of the Z specification. In this talk I will show how Fastest works on some toy examples and our current research efforts.

 

Bio:

Maximiliano Cristiá is professor of Software Engineering at Universidad Nacional de Rosario (Argentina) and head of the Software Engineering Group at CIFASIS (International Franco-Argentine Center for Information Sciences and Systems). His research interests include formal methods, particularly model-based testing, software architecture and tool development for the Software Engineer.
