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.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
