The origin of Galactic cosmic rays (with energies up to 10 15 eV) remains unclear, though it is widely believed that they originate in the shock waves of expanding supernova remnants [1][2]. Currently the best way to investigate their acceleration and propagation is by observing the γ-rays produced when cosmic rays interact with interstellar gas [3]. Here(More)
The diffuse extragalactic background light consists of the sum of the starlight emitted by galaxies through the history of the Universe, and it could also have an important contribution from the first stars, which may have formed before galaxy formation began. Direct measurements are difficult and 1 not yet conclusive, owing to the large uncertainties(More)
Long-term reliability of processors is experiencing growing attention since decreasing feature sizes and increasing power consumption have a negative influence on the lifespan. The reliability can also be influenced by Dynamic Power Management (DPM), since it affects the processor's temperature. In this paper, it is examined how different DPM-strategies for(More)
Long-term reliability of processors in embedded systems is experiencing growing attention since decreasing feature sizes and increasing power consumption have a negative influence on the lifespan. Among other measures, the reliability can be influenced significantly by Dynamic Power Management (DPM), since it affects the processor's temperature. Compared to(More)
