This technical report concerns the application of market based control to dynamic resource allocation within a utility data center or other distributed computing infrastructure. The report is intended to do two things. First, it demonstrates a possible instantiation of the market paradigm in an outsourced-services context, describing a suitable market mechanism and exemplifying agent bidding al...

We study energetics of a Josephson tunnel junction connecting a superconducting loop pierced by an external magnetic flux (an rf SQUID) and coupled to two independent thermal reservoirs of different temperature. In the framework of the theory of quantum dissipative systems, we analyze energy currents in stationary states. The stationary energy flow can be periodically modulated by the external ...

In cardiac fibrillation, disorganized waves of electrical activity meander through the heart, and coherent contractile function is lost. We studied fibrillation in three stationary forms: in human chronic atrial fibrillation, in a stabilized form of canine ventricular fibrillation, and in fibrillation-like activity in thin sheets of canine and human ventricular tissue in vitro. We also created ...

The aim of this paper is to present a method improving pitch estimation accuracy, showing high performance for both synthetic harmonic signals and musical instrument sounds. This method employs an Artificial Neural Network of a feed-forward type. In addition, octave error optimized pitch detection algorithm, based on spectral analysis is introduced. The proposed algorithm is very effective for ...

In this Article, Professor Christopher Yoo directly engages claims that mandating network neutrality is essential to protect consumers and to promote innovation on the Internet. It begins by analyzing the forces that are placing pressure on the basic network architecture to evolve, such as the emergence of Internet video and peer-to-peer architectures and the increasing heterogeneity in busines...

Affective agent architectures can be used as control components in Interactive Storytelling systems for artificial autonomous characters. Creative authoring for such systems then involves configuration of these agents that translate part of the creative process to the system’s runtime, necessarily constrained by the capabilities of the specific implementation. Using a framework for presenting c...

In this demonstrator, we will introduce the latest features and capabilities added to DataGraft – a Data-as-a-Service platform for data preparation and knowledge graph generation. DataGraft provides data transformation, publishing and hosting capabilities that aim to simplify the data publishing lifecycle for data workers (i.e., Open Data publishers, Linked Data developers, data scientists). Th...

This chapter presents an analysis of the prosodic and intonational structure of Catalan within the Autosegmental-Metrical (AM) framework (Pierrehumbert 1980, Pierrehumbert and Beckman 1988, Ladd 1996, Gussenhoven 2004, Jun 2005, and Beckman et al. 2005, among others). Based on this analysis, we have developed the Cat_ToBI system of prosodic annotation of Catalan corpora (Prieto, Aguilar, Mascar...

Ethical questions concerning problems of conducting delivery of enormously immature foetuses are subjected to intensive discussion and call for a permanent and wide consideration with the participation of all specialists, who are involved in the problem. The discussions have persisted over tens of years and became intensive particularly at the moment of defining the foetus viability. In the pre...
