This research involved revisiting an archaeological site in Siegerswoude, Friesland, the Netherlands, with a specific focus on remote sensing techniques. Remote sensing technology holds significant promise in archaeological research, providing a non-destructive method for archaeologists. Developed over …

Measuring plant health and status is key for growers in the Dutch greenhouse horticulture industry to create optimal conditions for plant growth and predictability and optimization of yield with minimal energy cost. Within the ‘Gewasgroei Goed Gemeten’ project led by The Hague University of Applied Sciences …

In Sicht von oben, ‘Powers of Ten’ und Bildpolitiken der Vertikalität (Spector Books, Leipzig, 2022) German media theorist and curator Vera Tollmann analyses the power aspects of the technical view from above. The context here is not so much the first manned flight with a balloon in 1783 in Paris but …

The transmission of constant-envelope orthogonal frequency division multiplexing (CE-OFDM) signals, based on electrical phase modulation, was shown to improve the tolerance to noise and the nonlinearity introduced by light-emitting diodes (LEDs) in visible light communication (VLC) systems. This allows …

The performance of a visible light communication (VLC) system based on power domain non-orthogonal multiple access (PD-NOMA) is experimentally evaluated in this paper. The simplicity of the adopted non-orthogonal scheme is provided by the fixed power allocation method at the transmitter and the single …

Light is a form of energy produced by a luminous object which occurs as electromagnetic radiation and is closely related to other forms like radio waves, microwaves, gamma rays, infrared, UV and X radiation. The different kinds of radiation can be classified by using wavelengths. Only a small section …

Background: Development of more effective interventions for nonspecific chronic low back pain (LBP), requires a robust theoretical framework regarding mechanisms underlying the persistence of LBP. Altered movement patterns, possibly driven by pain-related cognitions, are assumed to drive pain persistence, …

The goal of this thesis is achieving saturation intensity of 76.5 mW/cm2for 2S1/2F=1 - 2P1/2F = 2 transition in singly-ionized beryllium ions (Be+). By enlarging the optical power of a laser diode at 626.266 nm via a bow-tie cavity and converting to 313.133 nm using Second Harmonic Generation in a nonlinear …

In wheelchair sports, the use of Inertial Measurement Units (IMUs) has proven to be one of the most accessible ways for ambulatory measurement of wheelchair kinematics. A three-IMU configuration, with one IMU attached to the wheelchair frame and two IMUs on each wheel axle, has previously shown accurate …

Het objectiveren van de bewegingsuitslag (ROM) in gewrichten is een belangrijk onderdeel binnen de fysiotherapie. Het meest gebruikte valide meetinstrument, de goniometer, is onhandig in het gebruik waardoor vaak gekozen wordt voor een visuele inschatting welke erg onbetrouwbaar is. Smartphones nemen …
