Abstra t: Au tion me hanism design has traditionally been a largely analyti pro ess, relying on assumptions su h as fully rational bidders. In pra ti e, however, bidders behave unpredi tably, making them dif ult to model and ompli ating the design pro ess. To address this hallenge, we present an adaptive au tion me hanism: one that learns to adjust its parameters in response to past empiri al b...

The synthesis, structural characterization, electrical transport, optical, and magnetic properties of a new cation-radical salt, bis(ethylenedithio)tetrathiafulvalene hexafluorophosphate, ú-(BEDT-TTF)PF6, are reported. The X-ray structure was determined at 298 K and at 173 K. The primary difference at the two temperatures is that the PF6 anions are disordered at 298 K and ordered at 173 K. At 2...

Microblogging services have brought users to a new era of knowledge dissemination and information seeking. However, the large volume and multi-aspect of messages hinder the ability of users to conveniently locate the specific messages that they are interested in. While many researchers wish to employ traditional text classification approaches to effectively understand messages on microblogging ...

A lass of odes is said to rea h apa ity C of the binary symmetri hannel if for any rate R < C and any " > 0 there is a suÆ iently large N su h that odes of length N and rate R from this lass provide error probability of de oding at most ", under some de oding algorithm. The study of the error probability of expander odes was initiated in Barg and Z emor (2002), where it was shown that they atta...

Two methodologies for rain forest mapping in Amazonia using textural features derived from JERS-1 data are presented. The first one uses a set of pass-band filters, called Laws filters, combined by Principal Components Transformation so as to match a filter to the most undulated forest texture. Multiresolutional filters are derived for resolution levels 1 to 1/5 of the original. Texture energy ...

Computation intensive DSP applications usually require parallel/pipelined processors in order to meet specific timing requirements. Data hazards are a major obstacle against the high performance of pipelined systems. This paper presents a novel efficient loop scheduling algorithm that reduces data hazards for such DSP applications. This algorithm has been embedded in a tool, called SHARP, which...
