The aim of the ERAMIS project is to set up a network of Master's degree “Informatics as a Second Competence” among 9 beneficiary universities of Kazakhstan, Kyrgyzstan and Russia, and 5 European universities. This contribution presents how this network is implemented.
This paper describes an architecture-based dynamic adaptation model and framework for adaptive software systems. The framework provides for a reusable adaptation infrastructure and uses a layered architecture pattern....

software developers are often concerned with particular changes that are relevant to their current tasks: not all changes to evolving software are equally important. Specified at the language-level, we have developed ...

As modern software systems operate in a highly dynamic context, they have to adapt their behaviour in response to changes in their operational environment or/and requirements. Triggering adaptation depends on detectin...

We study the asymptotic throughput for a large-scale wireless ad hoc network consisting of n nodes under the generalized physical model. We directly compute the throughput of multicast sessions to unify the unicast and broadcast throughputs. We design two multicast schemes based on the so-called ordinary arterial road system and parallel arterial road system, respectively. Correspondingly, we derive the achievable multicast throughput by taking account of all possible cases of n
s
= ω(1) and 1 ≤ n
d
≤ n − 1, rather than only the cases of
$$n_s=\Uptheta(n)$$
as in most related works, where n
s
and n
d
denote the number of sessions and the number of destinations of each session, respectively. Furthermore, we consider the network with a general node density
$$\lambda \in [1,n]$$
, while the models in most related works are either random dense network (RDN) or random extended network (REN) where the density is λ = n and λ = 1, respectively, which further enhances the generality of this work. Particularly, for the special case of our results by letting λ = 1 and
$$n_s=\Uptheta(n)$$
, we show that for some regimes of n
d
, the multicast throughputs achieved by our schemes are better than those derived by the well-known percolation-based schemes.

Introduce the basic concept of best rational approximation and constructing procedure of the best rational approximation function in Laplace domain. By an illustrative example the design method of FOC based on best rational approximation is discussed. The performance comparison of transfer functions between the FOC obtained by best rational approximation method and conventional PID shows that it is effective to apply the method in design of FOC, which can guarantee maximum absolute error of amplitude frequency characteristic of approximation function in a given error tolerance.
In this research we conducted a systematic reviewon Global software Development (GSD) literature andperformed a survey to gather challenges associated with GSD projects as well as their mitigation strategies. We revie...
