On Scalable H-infinity Control

Many of the classical approaches to controller synthesis do not scale well for large and complex systems. This is mainly due to computational complexity and the lack of distributed structure in the resulting controllers. It is important that limitations on the information given and processed by sensors and actuators can be incorporated into the design procedure. However, such constraints may great

Women’s Bigger Burden : Disparities in Outcomes of Large Scale Land Acquisition in Sierra Leone

Women farmers make up a majority of small-scale food producers in sub-Saharan Africa. Despite their important role in the food and livelihood security of their households and communities, women continue to face substantial challenges in their rights of and access to land resources in the region. In a number of countries such as Sierra Leone where large-scale land acquisition is ongoing, we posit t

Refined modelling of the short-T2 signal component and ensuing detection of glutamate and glutamine in short-TE, localised, 1H MR spectra of human glioma measured at 3T

Short-TE 1H MRS has great potential for brain cancer diagnostics. A major difficulty in the analysis of the spectra is the contribution from short-T2 signal components, mainly coming from mobile lipids. This complicates the accurate estimation of the spectral parameters of the resonance lines from metabolites, so that a qualitative to semi-quantitative interpretation of the spectra dominates in pr
