The novel enhanced oil recovery (EOR) technique combining the reduction of oil/water (o/w) interfacial tensions (IFT) to ultralow values and generation of a foam drive for mobility control is known as foam-assisted chemical flooding (FACF). We present a well-controlled laboratory study on the feasibility of FACF at reservoir conditions. Two...

The next step after smart cities is the creation of digital or smart nations. A digital nation requires a national transformation across diverse institutions including the urban and rural areas of a society. Besides diverse social innovation initiatives, sustainability is a key aspect, so that rather than greenfield projects, long-term...

Existing empirical research on the link between ethnic minority concentration in residential environments and voting for the radical right is inconclusive, mainly due to major differences between studies in the spatial scale at which minority concentration is measured. We examined whether the presence of non-western ethnic minorities in the...

Based on a survey (N = 248 business managers) this study confirms that different types of innovation in IT products have a direct positive impact on IT firms’ business performance. The commoditization level of IT markets acts as a moderator dampening this positive relationship. This implies that IT firms should take existing commoditization...

In a semiconductor factory, integrated circuits (or chips) are constructed on top of slabs of silicon, called wafers. The construction of these wafers is complicated and many different processing steps are needed to gradually building the chip layer by layer. Of these steps, photolithography uses the most expensive equipment. Therefore, the...

We developed an impedance bridge that operates at cryogenic temperatures (down to 60 mK) and in perpendicular magnetic fields up to at least 12 T. This is achieved by mounting a GaAs HEMT amplifier perpendicular to a printed circuit board containing the device under test and thereby parallel to the magnetic field. The measured amplitude and...

Both security and efficiency are important performance areas of air transport systems. Several methods have been proposed to assess security risks and estimate efficiency independently, but only few of these methods identify relationships between security risks and efficiency performance indicators. To analyze security, efficiency, and the...

Synchronization and ranging in internet of things (IoT) networks are challenging due to the narrowband nature of signals used for communication between IoT nodes. Recently, several estimators for range estimation using phase difference of arrival (PDoA) measurements of narrowband signals have been proposed. However, these estimators are based...
