A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

This thesis analyses how a radiology department at the largest hospital in Sweden, Karolinska University Hospital, most profitably could expand its capacity for investigating cancer patients using magnetic resonance imaging (MRI). The queues today for patients waiting to be scanned are long, which delays the start of cancer treatments. Meanwhile the hospital has a budget deficit of half a billion SEK, which make any expansion hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these.

In Sweden the residential and commercial sector is a major user of energy, why the Swedish government has set a specific goal to half the energy usage in buildings by 2050, compared to 1995. The Swedish Energy Agency has therefore started the campaign ?Halvera Mera? to encourage demonstration projects that will show how to renovate in an energy efficient way, and in doing so prove that it is possible to reduce a building?s energy usage by half and still make a profit. These projects are intended to serve as good examples and give inspiration to residential owners to perform energy efficient renovations. To make sure that these projects serve their purpose, it is important to know what will inspire and what will impede a residential owner to invest in energy efficiency improvements.
