de Haan, Mick (author)Architectural engineering is evolving from a traditional craftsmanship to a new digital craftsmanship. Through advancements in production and processing techniques, we can achieve both mass production and offer mass customisation. As for the typology shown below, a simple house [1] & [2], the source of the material did not alter. The...master thesis 2017

Hunziker, J.W. (author), Slob, E.C. (author), Mulder, W. (author)In marine time-domain controlled-source electromagnetics (CSEM), there are two different acquisition methods: with horizontal sources for fast and simple data acquisition or with vertical sources for minimizing the effects of the airwave. Illustrations of the electric field as a function of space and time for various source antenna orientations,...journal article 2011

Vogelaar, B. (author), Smeulders, D.M.J. (author), Harris, J. (author)Seismic effects of a partially gas-saturated subsurface have been known for many years. For example, patches of nonuniform saturation occur at the gas-oil and gas-water contacts in hydrocarbon reservoirs. Open-pore boundary conditions are applied to the quasi-static Biot equations of poroelasticity to derive an exact analytic expression of the...journal article 2010

Chao, G.E. (author), Smeulders, D.M.J. (author), Van Dongen, M.E.H. (author)We present an exact theory of attenuation and dispersion of borehole Stoneley waves propagating along porous rocks containing spherical gas bubbles by using the Biot theory. An effective frequency-dependent fluid bulk modulus is introduced to describe the dynamic (oscillatory) behavior of the gas bubbles. The model includes viscous, thermal, and...journal article 2007

Spetzler, J. (author), Kvam, O. (author)Time-lapse seismic experiments aim to obtain information about production-related effects in hydrocarbon reservoirs to increase the recovery percentage. However, nonrepeatability problems such as acquisition differences, overburden effects, and noise are often significantly stronger than the imprint of production changes in time-lapse seismic...journal article 2006
