In order to further reduce the LCOE of PV, the conversion efficiency must increase beyond the practical limit of silicon technology (26% [1]). It is believed that tandem module technology, combining bottom c-Si cells with low-cost thin-film top cells, can overcome the silicon limit. Recently, bifacial glass/glass modules are gaining market share...

The Machine Directive, which contains the Health and Safety Requirements to warrant safe design of industrial (and commercial) machines, is currently being evaluated for amendment. These amendments should ensure that the Machine Directive is relevant for all machines that could be introduced on the work floor in the following 30 years. In this...

Recent developments have introduced so-called cobots or cooperative robots, which place the machines on the work floor next to employees. A new challenge arises to keep these human robot interactions, safe and healthy, while also maintaining the sustainability and efficiency of the interaction. Here, we present a model, which can be a valuable...

We give a formal verification procedure that decides whether a classifier ensemble is robust against arbitrary randomized attacks. Such attacks consist of a set of deterministic attacks and a distribution over this set. The robustness-checking problem consists of assessing, given a set of classifiers and a labelled data set, whether there exists...

The most simple grid connected PV system consists of a series connection of PV modules, connected to a string inverter. The power output of such a system can be sensitive to shade on a PV module. Also limited shade on a part of a cell can lead to high temperatures in that shaded cell, a so-called hotspot. The effect of shade can be reduced by...

Composite constructions are indispensable in current and future society. Fiber Bragg Gratings (FBGs) embedded in composite need to be carefully aligned with the material fibers to reduce inhomogeneous lateral load exerted onto the FBG which occurs due to the inhomogeneous nature of composite materials. Inhomogeneous load causes distortion of the...

An important aspect of human emotion perception is the use of contextual information to understand others' feelings even in situations where their behavior is not very expressive or has an emotionally ambiguous meaning. For technology to successfully detect affect, it must mimic this human ability when analyzing audiovisual input. Databases upon...

In 2017 TNO and GFZ combined a dense accelerometer based high resolution surface seismic survey with a fibre optic based Vertical Seismic Profiling (DAS VSP) survey. The combined survey took place on a narrow patch of land in a challenging, noisy urban environment, in Berlin, Germany. The objective was to demonstrate the possibility to acquire a...

The first diffraction gratings on curved substrates were manufactured by employing ruling engines by H.A. Rowland. Due to the ruling principle, these gratings are characterized by equidistant parallel lines if the line pattern is projected along the optical axis onto a tangential plane in the vertex of the grating substrate. The Offner...

Elastic guided waves are carriers of information of the (change in) condition of plate-like structures like windturbine blades, airplane wings and road surfaces on bridges. To measure these guided waves we do not have to use piezos. Other sensors offer interesting benefits like contactless sensing, embedding, or measuring without electricity....

We characterize four types of bifacial modules with three different methods that have been proposed by the community. One method approximates rear irradiance with increased front side irradiance. The other two utilize light directly radiating on the rear side of the module. We describe the setup, the calibration, and the resulting errors...

Innovations are necessary to achieve reduction of both CO2 emissions and use of fossil materi-als during construction and maintenance of roads. To enable selection of promising innovations and to facili-tate material selection in green procurement, quantitative tools to assess both life cycle costs and environmen-tal impacts are used.

The future of manned submarines is currently in question as a result of rapid developments in autonomy in other fields (e.g. autonomous cars). Therefore, the feasibility of an unmanned submarine, basically a large unmanned underwater vehicle (UUV), as a replacement for a conventional diesel-electric submarine (SSK), was investigated....

A modelling approach is described in which time-domain underwater-acoustic source functions are generated using a model that predicts the motion of air-bubbles generated by mini-airguns operated at various pressures. These time-series are Fourier-transformed to produce frequency-domain descriptions of the source. These are combined with complex...
