In this paper, for the first time, we propose and experimentally demonstrate a novel pairwise coding (PWC)-based multiband carrierless amplitude phase (mCAP) modulation with chaotic dual-mode index (DM) secure bandlimited visible light communication (VLC) systems. The combination of mCAP DM can sustain higher spectral efficiency (SE) compared conventional (IM), while PWC be employed to efficien...

Constructing a smart wheelchair on a commercially available powered wheelchair (PWC) platform avoids a host of seating, mechanical design and reliability issues but requires methods of predicting and controlling the motion of a device never intended for robotics. Analog joystick inputs are subject to black-box transformations which may produce intuitive and adaptable motion control for human op...

The European Neolithization process started around 12 000 years ago in the Near East. The introduction of agriculture spread north and west throughout Europe and a key question has been if this was brought about by migrating individuals, by an exchange of ideas or a by a mixture of these. The earliest farming evidence in Scandinavia is found within the Funnel Beaker Culture complex (Trichterbec...

Removing noise from signals which are piecewise constant (PWC) is a challenging signal processing problem that arises in many practical scientific and engineering contexts. In the first paper (part I) of this series of two, we presented background theory building on results from the image processing community to show that the majority of these algorithms, and more proposed in the wider literatu...

Many studies on the impact of psychosocial working conditions on health prove that psychosocial stress at work is an important risk factor endangering workers' health. Thus it should be constantly monitored like other work hazards. The paper presents a newly developed instrument for stress monitoring called the Psychosocial Working Conditions Questionnaire (PWC). Its structure is based on Rober...

Marschall F, Ferger K, Mueller H. Biological Variability in Submaximal Parameters of Performance and Strain. JEPonline 2014;17(4):102-112. The use of performance and strain parameters to evaluate training effects depends on the assessment of biological day-to-day variability. Without control of this variability, exerciseinduced effects cannot be separated and/or adequately interpreted. In five ...
