Commutativity of Reducers

In the Map-Reduce programming model for data parallel computation in a cloud environment, the reducer phase is responsible for computing an output key-value pair, given a sequence of input values associated with a particular key. Because of non-determinism in transmitting key-value pairs over the network, the inputs may not arrive at a reducer in a fixed order. This gives rise to the reducer co...

Reanalysis and Hypercorrection Among Extreme /s/ Reducers

Western Nicaragua is an immensely understudied region, and it also represents one of the most advanced coda /s/-weakening dialects of Spanish. Coda /s/ is reduced nearly categorically before a following consonant, vowel, or pause, e.g. cesta ‘basket’ becomes [sehta], más ajo ‘more garlic’ becomes [mah aho], and misas ‘masses’ becomes [misa], respectively. These reductions result in a “breathy S...

Lowering mechanical degradation of drag reducers in turbulent flow

Drag reduction (DR) agents are used in several ppm concentrations to accelerate significantly the flow through conduits in oil pipelines, oil well operations, flood water disposal, fire fighting, field irrigation, transport of suspensions and slurries, sewage systems, water heating and cooling systems, airplane tank filling, marine systems, and also in biomedical systems including blood flow. T...

PAPR Distribution Analysis at the Output of Nonlinear PAPR Reducers

Nonlinear PAPR reducers, such as clipping and companding techniques, are some simple methods used to reduce the Peak-to-Average Power Ratio (PAPR). In this paper, assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we investigate the PAPR distribution of an OFDM signal when it is passed through a nonlinear PAPR reducer. The obtained PAPR distribut...
