Recent robust stability analysis results for linear time-varying feedback interconnections are based on a time-varying generalisation of the nu-gap metric. The causality of closed-loop mappings is dealt with explicitly, rather than via well-posedness assumptions as is common in the literature. Here, an alternative time-varying gap metric is defined. It is shown that this gives rise to correspondin
In this paper we discuss social policy in relation to different development contexts, where characteristics and outcomes of social policies in different sectors ( e.g.,housing, care, education, social security) are compared. The paper relates to the discussion on the causes and outcomes of welfare state management in different contexts. However, existing analytical models do not fit the mixtures
A hybrid finite element method/method of moments (FEM/MoM) technique is used to analyze the performance of higher order hierarchical Legendre basis functions. The FEM is used to model the interior part of the computational domain and the MoM is used to model the boundaries. Higher order hierarchical H(curl) Legendre basis functions have been applied to represent the electric field in the three dim
A fiber-optical system for measurements of fast high voltage pulses has been developed. The system is based on capacitively coupled Pockels cell voltage sensor and features excellent rejection of electrical interference, large bandwidth and practically unlimited voltage range. The authors describe the principle of operation and give a preliminary discussion of the performance of the measurement sy
Using a system analysis approach compares different systems for handling and treatment of toilet waste and organic household waste. Design issues considered are source separation of urine, use of vacuum toilets and advanced nutrient recovery processes such as Reverse Osmosis (RO). All of the studied systems have low emissions of eutrophy ing compounds. Other environmental effects are mainly relate
