Zooming Process Graphics

Looks neat: ABB HawkEye is a research prototype of a new operator interface for process control. HawkEye is developed by ABB Strategic R&D for Oil, Gas & Petrochemicals.

New paper: An Industrial Case Study of Performance and Cost Design Space Exploration

Heiko — Fri, 06 Jan 2012 11:11:35 +0000

This paper shows how our software tools Palladio and PerOpteryx were used in capacity planning for a web-based remote diagnostics system at ABB. It will be presented at the International Conference on Performance Engineering (ICPE 2012) in April in Boston, US.

PerOpteryx results: CPU Utilization vs. costs; each dot represents a generated design alternative for the system. The diagram shows the trade-off between performance and costs.

Impact?

I noticed that our 2009 article on the Palladio Component Model is currently the most cited article of the Journal of Systems and Software during the last 5 years (77 citations). My 2010 performance evaluation survey is the most downloaded article from Elsevier’s Performance Evaluation Journal from July 2010 to June 2011.

Many thanks to all readers and downloaders, I feel humbled by the apparent interest in these works!

IEEE names ABB technologies among the 11 most important of the decade

Heiko — Tue, 25 Oct 2011 08:14:03 +0000

Along with smartphones and digital photography, FACTS has been named among the top 11 technologies of the decade by the IEEE. The 11 technologies named in the list include smartphones, social networking, voice over IP, LED lighting, cloud computing, multicore CPUs, digital photography, drone aircraft, class-D audio and planetary rovers. FACTS (flexible AC transmission systems) also finds a place in this illustrious list. FACTS is a family of technologies that ABB pioneered and has continuously developed over the past 60 years.

“With these technologies ABB can increase the capacity of existing lines by as much as 50 percent, reduce electrical losses in long distance power transfer and relieve grid congestion and transmission bottlenecks that prevent the flow of electricity,” said Ingela Hålling, head of FACTS within the Grid Systems business of the Power Systems division. “FACTS technologies can also help to minimize the risk of blackouts, and facilitate the integration of intermittent types of energy by rapidly countering voltage fluctuations or by storing large amounts of surplus power until it is needed.”

ABB has delivered around 800 FACTS installations worldwide, which is more than half the world total.

IEEE TSE paper accepted

A journal paper entitled “Architecture-Based Reliability Prediction with the Palladio Component Model” based on our QoSA 2010 conference paper was accepted in “IEEE Transactions on Software Engineering“. A preprint PDF is available here.

Kinect controlling ABB robot

Quote: “Today’s machinery is controlled by clunky levers and buttons. Most often, operators are having a hard time syncing their coordination with the machines. But now, as a new era of motion-control arrives, the Kinect can change the way we operate, the way we control machines. With the Kinect, precision handling of these constructs are on their way as users and operators can finally control machines through motion-based commands.”

Here are two new talks from CompArch 2011 on sustainability evaluation and multi-tenant software applications:

ICSE2011 SEIP Talk on Q-ImPrESS

Heiko — Sat, 28 May 2011 00:13:18 +0000

This is my talk at the ICSE 2011 Software Engineering In Practice Track. It’s about a large-scale case study on performance and reliability prediction for service-oriented software systems. Also see the Q-ImPrESS website for more details.

ABB’s FRIDA Offers Glimpse of Future Factory Robots

Heiko — Thu, 12 May 2011 19:33:42 +0000

“This headless, two-armed robot may be tomorrow’s factory worker. Its name is FRIDA, and it’s a creation of ABB, the Swiss power and automation giant, which introduced it early this month at the Hannover trade show, Europe’s largest industrial fair…”

Automated Transformation of Component-based Software Architecture Models to Queueing Petri Nets

Heiko — Sat, 23 Apr 2011 09:46:52 +0000

New paper accepted at MASCOTS 2011: “This paper contributes a formal mapping from PCM to QPN models, implemented by means of an automated model-to-model transformation as part of a new PCM solution method based on simulation of QPNs. The limitations of the mapping and the accuracy and overhead of the new solution method compared to existing methods are evaluated in detail in the context of five case studies of different size and complexity. The new solution method proved to provide good accuracy with solution overhead up to 20 times lower compared to PCM’s reference solver.”
