According to the Intergovernmental Panel on Climate Change report released in September 2014, unprecedented changes in temperature and precipitation patterns have been recorded globally in recent decades and further change is predicted to occur in the near future, mainly as the result of human activity. In particular, projections show that the Mediterranean(More)
In this paper we describe the architecture of SCAMPI (A Scaleable Monitoring Platform for the Internet). SCAMPI allows easy writing of monitoring applications, which can run on top of different network adapters without changing the code and which can provide detailed monitoring of high-speed Internet circuits. This is made possible by MAPI (Monitoring API)(More)
— Content distribution networks (CDN) have been increasingly used as the scalable solution to deliver high-quality multimedia content. However, despite the promising concept, current self-organizing content distribution networks (using real-time replica placement) lack placement and retrieval algorithms that are both intelligent and scalable. In this paper(More)
Losses of phosphorus (P) and nitrogen (N) have important influences on in-lake concentrations and nutrient loading to downstream ecosystems. We performed a series of mesocosm experiments along a latitudinal gradient from Sweden to Greece to investigate the factors influencing N and P loss under different climatic conditions. In six countries, a standardised(More)
Information on the effects of water level changes on microbial planktonic communities in lakes is limited but vital for understanding ecosystem dynamics in Mediterranean lakes subjected to major intra- and inter-annual variations in water level. We performed an in situ mesocosm experiment in an eutrophic Turkish lake at two different depths crossed with(More)
