Dol, H.S. (author), Blom, K.C.H. (author), van Riet, M.W.G. (author), van de Sande, J.J.M. (author)Stand-off mine countermeasure (MCM) operations with unmanned systems frequently require user involvement for the interpretation of image data, for classification and identification, and for decision-making during mine disposal. As the transfer of image data usually requires tethering, this leads to cumbersome operating procedures. We have...conference paper 2022

Bekers, D.J. (author)In this paper we revisit and generalize the Multi-Tone Sinusoidal Frequency Modulation (MTSFM), which has been used in the past decade for various Radar and Sonar applications including optimal transmit waveform design, modelling non-linear frequency modulation, high-duty cycle sensors . In its original form, the MTSFM describes a phase...conference paper 2022

Sberna, P.M. (author), Bernardis, A.F. (author), Garufo, A. (author), Bueno, J. (author), Llombart, N. (author), Neto, A. (author)Photo-conductive lens antennas (PCAs) exploit the ultra-short photoconductivity phenomenon of specific semiconductors in order to generate pulsed radiation in the THz regime. State of the art PCAs suffer from high dispersion and low radiation efficiency over the large generated bandwidth due to the poor coupling between the antenna and the...conference paper 2021

(author)With the introduction of fullband speech coding the question arises what role frequency components above 14 kHz play in speech quality assessment. On the one hand, our results show that bandwidth limitation from 24 kHz down to 14 kHz is not audible to even the most critical subject. On the other hand, 14-24 kHz band limited, audible levels of...article 2020

Fockens, T.W.H. (author), Zwamborn, A.P.M. (author), Leferink, F. (author)Radio noise of man-made origin has been measured and studied since the 50s of the past century. From that time on, especially in the last two decades, the electromagnetic environment has changed due to the wide spread and increasingly complicated electronic and computing equipment in domestic and work premises. Not only the character of man-made...article 2019

(author)Mixed-criticality (MC) multicore system design must reconcile safety guarantees and high performance. The interference among cores on shared resources in such systems leads to unpredictable temporal behaviour. Memory bandwidth regulation among different cores can be a useful tool to mitigate the interference when accessing main memory. However,...conference paper 2018

(author)Typically, ultrasonic flow meters assume linear wave propagation. Nevertheless, if the transducers of an ultrasonic flow sensor excite a pressure wave with a high amplitude, nonlinear wave propagation effects become significant. The appearance of higher harmonics increases the bandwidth of the received signal, which may potentially lead to a...conference paper 2018

(author)The IEEE 802.15.4 Time-Slotted Channel Hopping (TSCH) protocol defines two types of timeslots for communications, namely dedicated and shared timeslots. An upper layer in the protocol stack uses these timeslots to design a communication schedule for the network links, based on the required bandwidth for each link.
