This document describes given an analysis of the computer security aspects of the demonstrator developed in work package 12 of the Wireless Health and Care (WsHC) project. A risk analysis is performed and requirements for the system are established. The implementation of security measurements implemented in the demonstrator is discussed. Finally the risk analysis is revised according to the pro...

The homotopy Lie (L∞) categorification of D-particle field theory in the method of gauged S-duality spontaneous breakdown is investigated. We show the non-trivial definition of the D-particle fields category and give explicit formulae for its higher composition structures. As a result, we can recognize the physical significance of D-particle fields for determinism and undeterminism.

It is widely accepted that software measurement should be automated by proper tool support whenever possible and reasonable. While many tools exist that support automated measurement, most of them lack the possibility to reuse defined metrics and to conduct the measurement in a standardized way. This article presents an approach to anchor software measures on elements of the process model. This...

In this paper we deal with the problem of aggregating pairwise distance values in order to obtain a multi-argument distance function. After introducing the concept of functionally expressible multidistance, several essential types of multidimensional aggregation functions are considered to construct such kind of multidistances. An example of non functionally expressible multidistance is exhibited.

Queries are widely used for acquiring data distributed in opportunistically formed mobile networks. However, when queries are executed in such dynamic settings, the returned result may not be consistent, i.e., it may not accurately reflect the state of the environment. It can thus be difficult to reason about the meaning of a query’s result. Reasoning about imperfections in the result becomes e...

While aggregate data do not show the investment echoes predicted by vintage-capital models, echoes arise in rates of entry and exit of firms at the industry level. Moreover, industries where prices decline rapidly experience early ‘shakeouts’. The relation emerges naturally in a vintage-capital model in which exit of firms sometimes accompanies the replacement of their capital, and in which a s...

For the first time after 1979 revolution in Iran, the 2005 presidential election went to the second round. Not only neither candidates could win the majority of the votes in the first round, but the potential voters in the first round were fairly divided between the 7 candidates and abstention. It created a relatively rich menu of options for the voters to choose from, however by using data fro...
