KM3NeT broadcast optical data transport system

The optical data transport system of the KM3NeT neutrino telescope at the bottom of the Mediterranean Sea will provide more than 6000 optical modules in the detector arrays with a point-to-point optical connection to the control stations onshore. The ARCA and ORCA detectors of KM3NeT are being installed at a depth of about 3500 m and 2500 m,...

Crystalline silicon solar cells with thin poly-SiOx carrier-selective passivating contacts for perovskite/c-Si tandem applications

Single junction crystalline silicon (c-Si) solar cells are reaching their practical efficiency limit whereas perovskite/c-Si tandem solar cells have achieved efficiencies above the theoretical limit of single junction c-Si solar cells. Next to low-thermal budget silicon heterojunction architecture, high-thermal budget carrier-selective...

The impact of land-use change emissions on the potential of bioenergy as climate change mitigation option for a Brazilian low-carbon energy system

Land-use change (LUC)-related greenhouse gas (GHG) emissions determine largely whether bioenergy is a suitable option for climate change mitigation. This study assesses how LUC emissions influence demand for bioenergy to mitigate GHG emissions, and how this affects the energy mix, using Brazil as a case study. A methodological framework is...

Quantum dot arrays in silicon and germanium

Electrons and holes confined in quantum dots define excellent building blocks for quantum emergence, simulation, and computation. Silicon and germanium are compatible with standard semiconductor manufacturing and contain stable isotopes with zero nuclear spin, thereby serving as excellent hosts for spins with long quantum coherence. Here, we...

Review of camouflage assessment techniques

In military operations signature reduction techniques such as camouflage nets, low-emissive paints, and camouflage patterns are typically deployed to optimize the survivability of high value assets by minimizing their detectability. Various methods have been developed to assess the effectiveness of these camouflage measures. There are three main...

Memory Solutions for Flexible Thin-Film Logic: Up to 8kb, >105.9kb/s LPROM and SRAM with Integrated Timing Generation Meeting the ISO NFC Standard

Thin-film transistor (TFT) technologies have long been used predominantly for display fabrication and are attractive for large area, low cost and flexible circuit applications. Thanks to the improving performance of thin-film metal-oxide NFC tags and data processing chips on foil [1], [2], fabs are considering the large-scale production of...

Containerization of high level architecture-based simulations: A case study

NATO and the nations use distributed simulation environments for various purposes, such as training, mission rehearsal, and decision support in acquisition processes. Consequently, modeling and simulation (M&S) has become a critical technology for the coalition and its nations. Achieving interoperability between participating simulation systems...

Cost-effective industrial software rejuvenation using domain-specific models

Software maintenance consumes a significant and increasing proportion of industrial software engineering budgets, only to maintain the existing product functionality. This hinders the development of new innovative features with added value to customers. To make software development efforts more effective, legacy software needs to be rejuvenated...

Integration of functions within STUAS operator crew on board royal Netherlands Navy ships

Many reasons exist for the military to favor unmanned systems and future missions are envisioned that require longer, more diverse and more frequent deployment of UAVs with increased mission precision. This will also result in a much higher demand on operator crews working with UAVs. With the current pressure on operational budgets, a more...

Nanosar-case study of synthetic aperture radar for nano-satellites

Nano-satellites have a cost advantage due to their low mass and usage of commercial-off-the-shelf technologies. However, the low mass also restricts the functionality of a nano-satellite's payload. Typically, this would imply instruments with very low to low resolution and accuracy, essentially ruling out applications such as remote sensing....
