An optimal configuration of components is essential for providing good quality under all conditions. If the system becomes overloaded because the chip cannot process all data then this can, for example, give rise to the picture on the TV screen suddenly pausing or becoming deformed.
Building in larger chips is an expensive solution. Weffers-Albu developed a method to calculate the optimal configuration of software components and the optimal quantity of system resources (processor, memory) required in this type of equipment.
During the development of a mathematical model, Weffers-Albu imposed the requirements that the equipment should be cheaper and more reliable. Bearing this in mind, she described the effects decisions about priority and buffer size had on the performance of software components. She also calculated how the flow of information in a device had to be planned. Finally, in her calculations she included the option that a buffer memory can take care of the 'system overload'.
Thanks to her mathematical model, it is no longer necessary to carry out simulations during the design of the system configuration. The model can plan the data flow and arranges that data can be temporarily stored in a buffer in the event of overload. It also calculates the settings associated with a minimum overhead.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
