We report an experimental demonstration of signal amplification for a superfluid He interferometer by allowing the matter waves from two Josephson mass current sources to interact with the resonances within the experimental cell. We characterize the interferometer using an external phase shift and demonstrate a 30-fold enhancement in intrinsic phase sensitivity. We also demonstrate a truly cont...

The value of most experience-based information systems tends to degrade with time. To keep the value of such a system, evaluation and maintenance is an essential. While evaluation monitors the "value" over time, maintenance has to preserve or improve this "value". Evaluation and maintenance should not simply happen ad-hoc but systematically and based on specific quality and maintenance knowledg...

Most research in computer vision has been directed towards minimalistic approaches, in which problems are addressed on how properties of the environment can be computed from as little information as possible. Although such approaches may be scientifically well motivated they have only resulted in limited progress towards our understanding of seeing systems. Ballard, Bajcsy and others have point...

Continuous operation of alcohol dehydrogenase (ADH) catalysed enantioselective reduction in a biphasic sytem showed gains in productivity and stability of the overall reaction system. The total turnover numbers obtained for the cofactor NADP + are high with up to 1.5 10 4 . Productivity for (R)-2-butanol with Lactobacillus brevis ADH was up to 26 kmol (mol enzyme) 1 . Enantioselectivity was gre...

ABSTRACT This paper presents a novel microfluidic chip that exploits magnetic manipulation for integrated incubation and separation of microparticles in continuous flow. The chip integrates an active-mixing enhanced incubator and a magnetic fractionation-based separator. In the incubator, surface-functionalized magnetic beads capture target particles through specific binding, which is enhanced ...

The programme of qualification and improvement of materials for use in a fusion power station is crucial to the introduction of fusion power into the energy market and power plant studies are used to guide the targets for materials development. It is common to mis-interpret these targets as minimum values that must be achieved for fusion power to be a viable energy source, implying that failure...

The concept of energy aware software is introduced. A simple energy model for software is presented that separates the switching and leakage components and predicts its total energy consumption with less than 5% error for a set of benchmark programs. The experiments have been performed on the StrongARM SA-1100 microprocessor. A mathematical model for the total leakage current has also been prop...

The Solar, Anomalous, and Magnetospheric Particle Explorer (SAMPEX), the first of the Small Explorer series of spacecraft, was launched on July 3, 1992 into an 82' inclination orbit with an apogee of 670 km and a perigee of 520 km and a mission lifetime goal of 3 years. After more than 15 years of continuous operation, the reaction wheel began to fail on August 18,2007. With a set of three magn...

This article is concerned with frame constructions on domains and manifolds. The starting point is a unitary group representation which is square integrable modulo a suitable subgroup and therefore gives rise to a generalized continuous wavelet transform. Then generalized coorbit spaces can be defined by collecting all functions for which this wavelet transform is contained in a weighted Lp-spa...

Testing is vital for nowadays electronic systems. The related testing process consists in applying tests and verifying the obtained results. This should be performed without stopping the system under which useful applications are running. In this work, an on-line testing approach which allows tests to be applied in situ without any system perturbation is proposed. Using, optical probes fault ef...
