In this paper, we propose a novel inter-domain fast-authentication scheme based on a concept of "trust clouds". A trust cloud is formed among neighbouring access points based on a relationship among the owners of the access points. Fast-authentication for inter-domain sites is achieved through cooperation among the trust cloud members. The approach is distributed without a central authentication s

Although the concept of physical bounds for electrically small antennas was first introduced more than half a century ago by Wheeler and Chu it continuous to receive attention and still there is only a partial knowledge of these bounds. Most of the research effort in this field are based on the ideas of a stored energy in the different partial waves as introduced by Chu and, hence, suffers from th

Prosodic and lexical correlates of ‘clause-like’ and ‘paragraph-like’ boundaries associated with the Swedish discourse marker men ‘but/and/so’ are examined. Men-tokens in spontaneous monologues were labelled as to their boundary-status, first using text-only data. The ‘strong’ tokens (labelled identically by all labellers) were subsequently seen to be correlated with clear differences in the proso

The proper handling of alarms is crucial to automated process control. Fault Detection and Isolation techniques have been widely researched to determine such alarms. In practice, many alarms are only distractive and do not represent a fault situation. Here a toolbox, that uses an expert system called LARA, is proposed that aims to reduce the occurrence of so-called nuisance alarms. It is based on

To be able to predict the strength of climate change and its consequences for mankind, it is of major importance to understand the contemporary greenhouse gas exchange of the terrestrial biosphere, as well as its response to changes in climate. To achieve such understanding both descriptive studies and manipulation experiments are required. Northern peatlands represent an important ecosystem type

This paper presents the concept and initial work on a microfluidic platform for bead-based analysis of biological sample. The core technology in this project is ultrasonic manipulation and trapping of particle in array configurations by means of acoustic forces. The platform is ultimately aimed for parallel multistep bioassays performed on biochemically activated microbeads (or particles) using su

Distressed firms that are forced to liquidate assets in inefficient markets often have to accept prices that are substantially lower than the fair asset value. This asset illiquidity discount aggravates the financial situation of such firms and should be accounted for in risk management. This paper is the first to analyze financial hedging as a tool for avoiding exposure to the asset illiquidity d
