Maximum Power Efficiency. [PDF]
Entropy (Basel)New research often starts with vague, dream-like ideas, conversed on over coffee in the free flow of animated discussions about physics, the growing up of one’s children, politics, and the success of the local ice hockey team [...]

Universality of Efficiency at Maximum Power [PDF]
Physical Review Letters, 2009 We investigate the efficiency of power generation by thermo-chemical engines. For strong coupling between the particle and heat flows and in the presence of a left-right symmetry in the system, we demonstrate that the efficiency at maximum power displays universality up to quadratic order in the deviation from equilibrium. A maser model is presented to

Increasing the power efficiency of an IEEE802.11a Power Amplifier [PDF]
2005 IEEE 61st Vehicular Technology Conference, 2005 OFDM modulation is extensively used in many applications. However, it also exhibits high peak-to-average power ratios (PAPR) requiring the associated transmit amplifier to have a very large linear region. This linear amplifier does therefore have poor power efficiency. To reduce the PAPR, cupping and filtering was carried out at baseband.

Investigating power efficiency of mergesort [PDF]
The Journal of Supercomputing, 2019 Excessive power consumption emerged as a major obstacle to achieving exascale performance in next-generation supercomputers, creating a need to explore new ways to reduce those requirements. In this study, we present a comprehensive empirical investigation of a power advantage anticipated in the mergesort method based on identifying a feature expected ...

The efficient calculation of powers of polynomials [PDF]
13th Annual Symposium on Switching and Automata Theory (swat 1972), 1972 Suppose we are given a polynomial P(x1,…,xr) in r≥1 variables, let m bound the degree of P in all variables xi, 1≤i≤r, and we wish to raise P to the nth power, n>1. In a recent paper which compared the iterative versus the binary method it was shown that their respective computing times were O(m2rnr+1) versus O(mn)2r) when using single precision ...

Power-Efficient DRAM Speculation [PDF]
2008 IEEE 14th International Symposium on High Performance Computer Architecture, 2008 Power-efficient DRAM Speculation (PEDS) is a power optimization targeted at broadcast-based shared-memory multiprocessor systems that speculatively access DRAM in parallel with the broadcast snoop. Although speculatively accessing DRAM has the potential performance advantage of overlapping DRAM latency with the snoop, it wastes power for memory ...
