A new method is proposed to analyze antenna arrays including mutual coupling (MC), which is based on the concept of multiple scattering, and relates to the iterative Jacobi and Gauss–Seidel methods. The method employs sampled far-field data of an isolated element, which can be obtained by any full-wave simulator and consists of far fields for...

The use of wireless acoustic sensor networks (WASNs) has received increased attention over the last decade. The advantages of WASNs over stand-alone multi-microphone devices are that the microphone array is not anymore limited by the dimensions of a single device, and that microphones can be placed at arbitrary locations. One of the...

Increased precision of gun-launched ammunition can reduce collateral damage and increase stand-off distance. It can maximize the tactical advantage of each shot and reduce the number of rounds needed to achieve mission success. Worldwide, technology for controlled smart munitions is being researched and demonstrated in various implementations....

In the past decades, there has been an extensive research interest in the areas of both waveform diversity/design and advanced signal processing algorithms departing from the more classical solutions based on Linear Frequency Modulated (LFM) pulses and Matched Filters (MF). In the waveform diversity community, especially within the context of...

Continuous navigation is crucial for small drones when flying a pre-planned route or during autonomous flight. In scenarios where a global positioning system (GPS) signal is unavailable, drift in the onboard sensors causes the inertial navigation system (INS) to quickly deviate from the planned route. This paper proposes a radar-aided navigation...

Data and statistics are key to soccer analytics and have important roles in player evaluation and fan engagement. Automatic recognition of soccer events - such as passes and corners - would ease the data gathering process, potentially opening up the market for soccer analytics at non professional clubs. Existing approaches extract events on...

This paper introduces non-cooperative games on a network of single server queues with fixed routes.Aplayer has a set of routes available and has to decide which route(s) to use for its customers. Each player’s goal is to minimize the expected sojourn time of its customers. We consider two cases: a continuous strategy space, where each player is...

Nerve agent exposure is generally treated by an antidote formulation composed of a muscarinic antagonist, atropine sulfate (ATR), and a reactivator of acetylcholinesterase (AChE) such as pralidoxime, obidoxime (OBI), methoxime, trimedoxime or HI-6 and an anticonvulsant. Organophosphates (OPs) irreversibly inhibit AChE, the enzyme responsible for...

Defensie kampt met een tekort aan chauffeurs in bepaalde delen van de logistieke keten. De innovaties op het gebied van truck platooning in de civiele markt kunnen hier een antwoord op bieden. Bij truck platooning zijn vrachtwagens in een konvooi elektronisch aan elkaar gekoppeld, waarbij de voorste truck de snelheid en route bepaalt en de...

Food insecurity is a growing concern due to man-made conflicts, climate change, and economic downturns. Forecasting the state of food insecurity is essential to be able to trigger early actions, for example, by humanitarian actors. To measure the actual state of food insecurity, expert and consensus-based approaches and surveys are currently...

Long-range horizontal path imaging through atmospheric turbulence is hampered by spatiotemporally randomly varying shifting and blurring of scene points in recorded imagery. Although existing software-based mitigation strategies can produce sharp and stable imagery of static scenes, it remains highly challenging to mitigate turbulence in scenes...

This article presents latest developments on mm-wave microstrip antennas in package at TNO. Two designs examples for 5G applications are presented: a 28 GHz Antenna in Package (AiP) module for mobile handset and a 26 GHz array antenna for base stations (BS), both in dual linear polarization. The AiP module consists of 2 linear arrays for...

Current object recognition techniques are based on deep learning and require substantial training samples in order to achieve a good performance. Nonetheless, there are many applications in which no (or only a few) training images of the targets are available, whilst they are well-known by domain experts. Zero-shot learning is used in use cases...

The disruption of a Critical Infrastructure (CI) or a Critical Information Infrastructure (CII) may have a serious impact on the society. The pervasive web of CI/CII dependencies has the potential to cause exceptional damage and societal disruption and may be hard to secure and govern. To understand the underlying threat causes of CI and CII...

Cyberspace is na land, zee, lucht en de ruimte het vijfde operationele domein van de krijgsmacht. Ook hier treedt Defensie op om de veiligheid van Nederland te beschermen. Daarvoor ontwikkelt Defensie operationele cybercapaciteiten. Deze kunnen desgewenst ook worden ingezet als nichecapaciteit bij bondgenootschappelijk optreden. De huidige...

Homicide investigators in the digital era have access to an increasing amount of data and the processing of all persons of interest and pieces of evidence has become nearly impossible. This paper describes the development and evaluation of a case-specific element library (C-SEL) that can be used to incorporate and prioritize persons of interest...

Emotional state during food consumption is expected to affect food pleasantness. We hypothesize that a negative emotional state reduces food pleasantness and more so for novel foods than for familiar foods because novel foods have not yet been associated with previous emotions. Furthermore, we expect this effect to be stronger when judging the...

Person re-identification (Re-ID) is a valuable technique because it can assist in finding suspects after a terrorist attack. However, the machine learning algorithms for person Re-ID are usually trained on large datasets with images of many different people in a public space. This could pose privacy concerns for the people involved. One way to...
