Human activities have changed the acoustic environment of many terrestrial and aquatic ecosystems around the globe. Mounting evidence indicates that the resulting anthropogenic noise can impact the behaviour and physiology of at least some species in a range of taxa. However, the majority of experimental studies have considered only immediate responses to single, relatively short-term noise eve...

In this paper, we propose a language, called Hierarchical Temporal Logic (HTL), for specifying queries on video databases. The language is based on the hierarchical as well as temporal nature of video data. We give similarity based semantics for the logic, and give efficient methods for computing similarity values for subclasses of HTL formulas. Experimental results, indicating the effectivenes...

A voting scheme constitutes an essential component of many fault tolerant systems. Two types of voters are commonly used in applications of real-valued systems: the inexact majority and the amalgamating voters. The inexact majority voter effectively isolates erroneous modules and is capable of reporting benign outputs when a significant disagreement is detected. However, an application specific...

Five male subjects performed three successive incremental work tests on an electronically braked cycle ergometer. The first and second tests were separated by thirty minutes of rest, the second and third by three minutes of maximum work. During the third test, venous blood lactate concentrations were still decreasing at work rates where they were increasing during the first two tests. The work ...

Mechanical, magnetic, and transport properties of arbitrary inhomogeneous composites are investigated by a Bruggeman-type mean-field approach. The theory yields materials parameters as functions of the volume fractions, geometries, and materials constants of the phases. Each system is described by a single response parameter g, which is equal to the percolation threshold of the composite. For m...

Financial instruments traded in the market, very often, are subject to default risk. It is well known that the default risks of different instruments are dependent on each other. In this paper, we consider a portfolio selection problem where assets are exposed to dependent default risk. Two different models are proposed to model the default mechanism: the Threshold Model and the Independence Mo...

A dynamic threshold sharing scheme is one that allows the set of participants to expand and contract. In this work we discuss dynamic threshold decryption schemes using bilinear pairing. We discuss and analyze existing schemes, demonstrate an attack and construct a significantly more efficient secure scheme.

Airport departure operations constitute an important source of airline delays and passenger frustration. Excessive surface traffic is the cause of increased controller and pilot workload; It is also the source of increased emissions; It worsens traffic safety and often does not yield improved runway throughput. Acknowledging this fact, this paper explores some of the feedback mechanisms by whic...

PURPOSE The aim of this study was to quantify the intensity of competition during two professional bicycle stage races: the Tour de France (Tour) and Vuelta a España (Vuelta). METHODS The HR responses of 18 world class cyclists were recorded during the races and compared with HR ranges that corresponded to four intensities of exercise that were measured in the laboratory with an incremental t...

In this contribution electrical transport and morphological properties of composite structures studied by the help of computer experiment are presented. The structures generated by the hard-sphere model embody tunnel mechanism of conductivity and the classical terms of the percolation theory are redefined. Correlations between electric transport and morphological properties of these structures ...
