The Autonomic Operating System Research Project - Achievements and Future Directions

Traditionally, hypervisors, operating systems, and runtime systems have been providing an abstraction layer over the bare-metal hardware. Traditional abstractions, however, do not consider for non-functional requirements such as system-level constraints or users' objectives. As these requirements are gaining increasing importance, researchers are looking into making user-specified and system-level

Tomography problems arising in Synthetic Aperture Radar

This paper gives a mathematical tutorial on Synthetic Aperture Radar (SAR). We see that with the usual mathematical model, the SAR reconstruction problem reduces to a problem in integral geometry. A number of mathematical problems are posed; the paper concludes with a short description of the basic idea underlying the algorithms used in most present systems. The challenge to the mathematical commu

Mapping societal functions, flows and dependencies to strengthen community resilience – results from an initial study

Communities are becoming increasingly dependent on critical societal functions and flows, such as energy supply, transportation of goods and people, school and health care. Dependencies between these functions and flows are also increasing. These trends imply that disruptions in the functions and flows may quickly lead to large societal consequences through domino effects which may be very difficu

N2O and NO emission from the Nyungwe tropical highland rainforest in Rwanda

Tropical forest soils are a significant source for N2O and NO. Current estimates of N2O and NO emissions areuncertain due to the limited number of fieldmeasurements and model input data. Furthermore, considerable spatialand temporal variability exists due to variation of soil properties, vegetation characteristics and meteorology.Weused a process-based model (ForestDNDC-tropica) to estimate N2O an

The present paper reviews studies carried out by the Bandim Health Project during the armed conflict in Guinea-Bissau, 1998-1999. Common health interventions like vaccination and breastfeeding, as well as focused interventions such as nutrition interventions aimed at malnourished children are effective measures. Population-based studies of health status gives important information about health con
