Papaefthymiou, G. (author), Klöckl, B. (author)This paper contributes a Markov chain Monte Carlo (MCMC) method for the direct generation of synthetic time series of wind power output. It is shown that obtaining a stochastic model directly in the wind power domain leads to reduced number of states and to lower order of the Markov chain at equal power data resolution. The estimation quality of...journal article 2008

Bolatkale, M. (author), Breems, LJ (author), Rutten, Robert (author), Makinwa, K.A.A. (author)A 4 GHz third-order continuous-time ΔΣ ADC is presented with a loop filter topology that absorbs the pole caused by the input capacitance of its 4-bit quantizer and also compensates for the excess delay caused by the quantizer's latency. The ADC was implemented in 45 nm-LP CMOS and achieves 70 dB DR and -74 dBFS THD in a 125 MHz BW, while...journal article 2011

Chae, Y. (author), Souri, K. (author), Makinwa, K.A.A. (author)A 20-bit incremental ADC for battery-powered sensor applications is presented. It is based on an energy-efficient zoom ADC architecture, which employs a coarse 6-bit SAR conversion followed by a fine 15-bit ΔΣ conversion. To further improve its energy efficiency, the ADC employs integrators based on cascoded dynamic inverters for extra gain and...journal article 2013

Remøy, H.T. (author), van der Voordt, Theo (author)Conversion into housing is a way of adapting and reusing vacant office buildings. Former research has shown possibilities for this type of conversion, and has delivered instruments for determining the conversion potential of vacant offices. While adaptation and renovation of outdated offices can prove to be a successful real estate strategy,...journal article 2014

Junicke, H. (author), Abbas, B. (author), Oentoro, J. (author), Van Loosdrecht, M. (author), Kleerebezem, R. (author)Identification of individual biomass concentrations is a crucial step towards an improved understanding of anaerobic digestion processes and mixed microbial conversions in general. The knowledge of individual biomass concentrations allows for the calculation of biomass specific conversion rates which form the basis of anaerobic digestion models....journal article 2014

Junicke, H. (author), Van Loosdrecht, M.C.M. (author), Kleerebezem, R. (author)Many anaerobic conversions proceed close to thermodynamic equilibrium and the microbial groups involved need to share their low energy budget to survive at the thermodynamic boundary of life. This study aimed to investigate the kinetic and thermodynamic control mechanisms of the electron transfer during syntrophic butyrate conversion in non...journal article 2015

Zong, Z. (author), Babaie, M. (author), Staszewski, R.B. (author)This paper proposes a mm-wave frequency generation technique that improves its phase noise (PN) performance and power efficiency. The main idea is that a fundamental 20 GHz signal and its sufficiently strong third harmonic at 60 GHz are generated simultaneously in a single oscillator. The desired 60 GHz local oscillator (LO) signal is delivered...journal article 2016

van Turnhout, J. (author)The dielectric spectra of colloidal systems often contain a typical low frequency dispersion, which usually remains unnoticed, because of the presence of strong conduction losses. The KK relations offer a means for converting ε′ into ε″ data. This allows us to calculate conduction free ε″ spectra in which the l.f. dispersion will show up...journal article 2016

Gorte, B.G.H. (author), Zlatanova, S. (author)The paper presents a very straightforward and effective algorithm to convert a space partitioning, made up of polyhedral objects, into a 3D block of voxels, which is fully occupied, i.e. in which every voxel has a value. In addition to walls, floors, etc. there are 'air' voxels, which in turn may be distinguished as indoor and outdoor air....journal article 2016

(author)In this paper, a user interface paradigm, called Talk-and-Tools, is presented for automated e-coaching. The paradigm is based on the idea that people interact in two ways with their environment: symbolically and physically. The main goal is to show how the paradigm can be applied in the design of interactive systems that offer an acceptable...journal article 2017

(author)Although post-traumatic stress disorder (PTSD) is well treatable, many people do not get the desired treatment due to barriers to care (such as stigma and cost). This paper presents a system that bridges this gap by enabling patients to follow therapy at home. A therapist is only involved remotely, to monitor progress and serve as a safety...journal article 2017
