An 5.1 μW, 1.8 V, 8-bit, successive approximation (SAR) analog-to-digital converter (ADC) using 10 kHz clock was designed and fabricated in a 0.18 μm CMOS technology for passive UHF radio frequency identification (RFID) applications. The ADC utilises a resistive digital to analog converter (DAC...
The effect of 10% pre-ageing deformation on the early precipitation behaviour in an AA6060 Al–Mg–Si alloy aged 10 min at 190°C was investigated by high-resolution transmission electron microscopy (HRTEM) in 100Al projections. The precipitate nucleation was heterogeneous since all precipitates were...
We refine two low-order structure factors of the skutterudite CoSb3 using convergent beam electron diffraction. The relatively large unit cell of this material causes the disks to overlap and introduces a series of challenges in the refinement procedure. These challenges and future work-arounds are...
Multi-wire sawing of silicon wafers is a tribological process. Slurry consisting of small silicon carbide particles embedded in polyethyleneglycol carries out the abrasive material removal process. During this process small silicon chips are removed from the bulk material. Low coherence...
A model is developed for calculation of the radon concentration in indoor air. The model takes into account various important parameters, e.g. radon concentration in ground, radon diffusion resistance of radon barrier, air permeance of ground, air pressure difference between outdoor ground and...
A feasibility study has been done for comparing a concept based on subsea tunnels and caverns with traditional development strategies for offshore oil fields. A realistic oil field off the shore of northern Norway has been studied. The concept includes 2 or 3 tunnels descending from the terminal...
This article describes a group of developers and how they successfully use Fitness. The study is based on interviews with 4 consultants, and shows that automated acceptance testing was used in two steps every iteration: a specification step where it helped communicate requirements, and a...
