This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Fresnel zone plates (FZPs) recently showed significant improvement by focusing soft X-rays down to ∼10 nm. In contrast to soft X-rays, generally a very high aspect ratio FZP is needed for efficient focusing of hard X-rays. Therefore, FZPs had limited success in the hard X-ray range owing to difficulties of manufacturing high-aspect-ratio zone plates using conventional techniques. Here, employing a method of fabrication based on atomic layer deposition (ALD) and focused ion beam (FIB) milling, FZPs with very high aspect ratios were prepared. Such multilayer FZPs with outermost zone widths of 10 and 35 nm and aspect ratios of up to 243 were tested for their focusing properties at 8 keV and shown to focus hard X-rays efficiently. This success was enabled by the outstanding layer quality thanks to ALD. Via the use of FIB for slicing the multilayer structures, desired aspect ratios could be obtained by precisely controlling the thickness. Experimental diffraction efficiencies of multilayer FZPs fabricated via this combination reached up to 15.58% at 8 keV. In addition, scanning transmission X-ray microscopy experiments at 1.5 keV were carried out using one of the multilayer FZPs and resolved a 60 nm feature size. Finally, the prospective of different material combinations with various outermost zone widths at 8 and 17 keV is discussed in the light of the coupled wave theory and the thin-grating approximation. Al2O3/Ir is outlined as a promising future material candidate for extremely high resolution with a theoretical efficiency of more than 20% for as small an outermost zone width as 10 nm at 17 keV. © 2013 International Union of Crystallography Printed in Singapore-all rights reserved.

It is demonstrated that a transition from paramagnetic behavior to clear room-temperature ferromagnetism (RTFM) exists in pure bulk ZnO. A significant enhancement of RTFM has been observed in argon-annealed ZnO samples. Quantitative chemical analysis unambiguously indicates that oxygen-related vacancies at surface play a crucial role in this observed RTFM. We suppose that the surface magnetic states, paramagnetic in the pure nanoparticles, are converted to ferromagnetic phase after mechanical compaction. Additionally, it is found that weakly adsorbed carbon species could block the exchange coupling between isolated magnetic moments in the surface layers. © 2013 AIP Publishing LLC.

Anticipation of future events is crucial for driving performance and safety. The aim of this study is to assess the relevance of theoretical frameworks of response preparation (response priming, movement integration theory) for driving. In a customised lane change task, valid and invalid primes were used to indicate the direction of the forthcoming lane changes. Reaction time (RT) and phase durations from steering movements served as dependent measures. In agreement with the theoretical considerations, we found a clear effect of validity on RT and steering kinematics. RTs were faster and the duration of the initial steering phase was shorter with valid than with invalid advance information. The experimental outcomes suggest that the theoretical considerations about benefits and costs of response preparation can be generalised to driving manoeuvres. Therefore, response priming paradigms might be well suited to investigate preparatory effects of advance information, e.g. in the context of advanced driving assistance systems.Practitioner summary: Benefits and costs of response preparation were assessed in the context of driving. The findings suggest that the understanding of preparatory processes is of relevance to enhance driving performance and safety. It is possible to derive some implications that may be useful for the design of assistance and information systems. © 2013 Copyright Taylor and Francis Group, LLC.

Devices to provide one-way data transfer are known as one-way gateways and used in various security applications. The main problem to be solved by one-way gateways is to make secure communication between network segments with different security levels to maintain multilevel security policy. Although one-way gateways are utilized in lot of information systems, there is no solution, including 'air gap', to assure one-way transfer in fact and they are not resistant against data leakage via covert channels. We analyzed state of the art technologies and products supporting one-way data transfer, worked out the requirements for one-way gateway with assured data transmitting. We designed the algorithm and protocol of assured data transfer and proposed the detailed device scheme. Then we build the program modelling the interaction between communication parties and the one-way gateway. This program was tested and some recommendations of its implementation were given. © 2016 IEEE.

A modular system for continuously insulating exterior walls of a structure and cladding the structure walls provides thermally isolated MFI-brackets secured to a structural wall supporting thermally isolated vertical or horizontal rails supporting exterior cladding. Thermal insulation is positionally retained against the structure wall interior of the exterior cladding by the MFI-brackets and a pressure equalized moisture controlling rain screen is maintained between the interior surface of the exterior cladding and an exterior facing surface of the insulation.
