Improving the performance of the trolley supply chain with a focus on visibility.
No full textThe lack of visibility, significant investment and a presumption of fleet shrinkage falter the decision-making process of a Dutch airline. Five decision areas have been identified and for each decision area improvements strategies or alternatives have been designed. Selecting the best alternative per decision area is a multi-criteria decision making problem. Therefore, a more sophisticated method is required to support the decision-maker. For this problem the novel Best-Worst Multi-Criteria Decision Making Method (BWM) has been selected. The BWM has been successfully applied to select the best alternative per decision area. Next steps for the airline are the implementation of the chosen alternatives.SEPAMTransport & LogisticsTechnology, Policy and Managemen
Buckfast Abbey Archaeological Projects 1982-2016 Photographic Archive

Brown (Proceedings of the Devon Archaeological Society 46, 1988, 13-89; and Devon Archaeological Society Occasional Paper 21, 2018) and the series of more detailed interim archive reports appearing on the ADS website (unpublished grey literature, accessible via author Stewart Brown)
Environment-insensitive two-photon ratiometric probe for in cellulo quantitative measurement of hydrogen peroxide
No full textThe quantitative analysis of a biological analyte directly through fluorescence imaging is essential in biomedical sciences but remains as a challenge owing to the environment-sensitive nature of fluorescence intensity. We show that a fluorescent hydrogen peroxide probe based on an in cellulo super-bright benzothiazolyl-benzocoumarin dye of which emission properties are insensitive to environmental changes offers a reliable and practical means for the quantitative analysis of hydrogen peroxide in cells and tissues directly through ratiometric imaging both under one-photon and two-photon excitation conditions. Different cellular hydrogen peroxide concentrations were determined for several cell lines and also for tumour and normal tissues. © 2021 The Author(s)11Nscopu

Simulation study of 8PSK and CE16PSK signals for satellite transmissions
No full textThe paper presents the results of an extensive series of computer-simulation tests to determine the effects of nonlinear distortion and adjacent channel interference (ACI) on the tolerances to noise of an uncoded eight-phase-shift-keyed (8PSK) signal and a rate-3/4 convolutionally encoded 16-ary phase-shift-keyed (CE16PSK) signal for transmitting over satellite channels. Both signals have the same theoretical spectral efficiency of 3 bit/s/Hz, but the CE16PSK signal has an asympototic coding gain of 4 dB over the uncoded 8PSK signal. Several different earth stations are assumed to have simultaneous access to a given transponder in a satellite by frequency division multiple access, so that ACI can be introduced into the wanted channel by the channels in the immediately frequency bands. It is assumed in the study that the high-power amplifier (HPA) of each earth station may or may not introduce nonlinear distortion into the transmitted signal, but the satellite transponder is linear. The optimum performances of the systems are compared with these using a rate-3/4 convolutionally encoded 16-ary quadrature-amplitude-modulated (CE16QAM) signal and a rate-3/4 convolutionally encoded 16-ary amplitude-phase-modulated (CE16APM) signal. It has been shown that, in the absence of ACI, the CE16PSK system has advantages of 1.3 dB, 2.6 dB and 2.8 dB over the CE16APM, CE16QAM and 8PSK signals, respectively, at a bit-error rate of 10-4; and, in the presence of ACI, the advantages are 0.6 dB, 1.3 dB and 3.5 dB, respectively.link_to_subscribed_fulltex
