Luminance variations are ambiguous: they can signal changes in surface reflectance or changes in illumination. Layer decomposition-the process of distinguishing between reflectance and illumination changes-is supported by a range of secondary cues including colour and texture. For an illuminated corrugated, textured surface the shading pattern comprises modulations of luminance (first order, LM...

This article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. The electrostatic actuation was induced by applying AC-DC voltage between the microbeam and electrode plate. In contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. In additio...

Decision support is needed within design processes in order to take into account all the aspects of life cycle assessments (LCA). In order to develop appropriate tools for decision support in design processes, it is necessary to found them on an understanding of design. The framework of methodical design as developed at the University of Twente is extended to integrate the specific LCA aspects....

The oceanic sound scattering layer (SL) is an ubiquitous acoustic signature of mesopelagic fishes and invertebrates that are important food sources for the oceanic macrofauna and players in the biological carbon pump. We investigated the relationship between SL migration amplitude and light in the Norwegian Sea. Incoming surface irradiance was measured continuously during night and day. The inc...

Using a hybrid density-functional theory (DFT) calculation including spin-orbit coupling (SOC), we predict that the zigzag antiferromagnetic (AFM) ground state of the honeycomb layered compound Na₂IrO₃ opens the observed insulating gap through a long-range magnetic order. We show that the effect of SOC and the correction of self-interaction error inherent in previous local or semilocal DFT calc...

This essay considers the healing potential of Architecture through the gentle but persistent power of Systems Intelligence. The premises for this deliberation come from the mundane life of a dweller and her encounters in space. Home is seen as the interpreter of a person’s inner world and as a potential catalyst for a change into a more humane and dignified life. Furthermore the process of buil...

The provision of software radio features in 3rd generation mobile systems enables terminal and system flexibility for the support of platform independent services and migration of 2nd generation mobile systems. To achieve adaptivity of UMTS terminals and system, a new modelling and design approach is necessary. This contribution presents a novel architecture model related to dynamic aspects and...

The development and local structure of height-selected 3-layer Ag islands on fivefold surfaces of icosahedral Al-Pd-Mn quasicrystals is characterized by STM for Ag deposition at 365 K. Heterogeneous nucleation of pseudomorphic single layer high islands is followed by rapid formation of 2nd and 3rd layers and subsequent lateral spreading, where each of these 3 layers consists of a family of nonf...
