Localization of an RF source inside the Human body for Wireless Capsule Endoscopy

This paper presents a method based on the phase dierence of arrival and the non-linear least square estimation to lo- calize a radio-frequency (RF) source, e.g a wireless capsule endoscope, inside the human body. The phase dierence of arrival at multiple frequencies of a signal is used to estimate the distance of the source to a receiver. The linear least square estimation is used to estimate the

The role of institutional innovations in the transition to low-carbon futures

Deep cuts in carbon emissions to avoid dangerous climatic change will require fundamental transformations of the energy and transport systems. This is an enormous challenge for society and the political system. In order to tackle this challenge, we argue that it will be necessary to develop new institutions and institutional practices that address and give priority to long-term climate policy obje

A new finite element formulation of shock-induced hull cavitation

A new formulation for non-linear, elastic wave propagation, based on the pressure and density, is introduced. The formulation accounts for a non-linear relation between speed of sound and density. The pressure and density are interpolated by identical shape functions between the nodes. The equation of state is introduced in the discretized system, hence the non-linearity is enforced point-wise. Th

On Family, Work, Money, and Morals: Intergenerational Value Differences in China

In which ways has China‘s rapid social change crystallized into differences between its generations’ values? The significance of intergenerational value gaps in values involving work,family, materialism, and individualism is reported based on a mixed-methods approach. A set of qualitative interviews with businessmen and their fathers was conducted in Shanghai in late 2005. Semi-structured intervie

Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts

Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. This thesis concerns how it is possible to decrease the operat
