The increasing capacity of offshore wind energy around the world brings challenges in Operation and Maintenance (O&M) management. Over the past years, many studies have focused on developing sound maintenance strategies in order to minimize maintenance cost or maximize availability. One of the promising maintenance strategies is...

In this paper, we propose a learning-aided signal processing solution for channel estimation in 5G new radio (NR). Channel estimation is an important algorithm for baseband modem design. In 5G NR, estimating the channel is challenging due to two reasons. First, the pilot signals are transmitted over a small fraction of the available time...

This paper discusses the advantages and an example of using shaped elevation patterns for 5G base stations. A simple iterative power synthesis method involving the phase of shaped patterns, and suitable for both center- and end-fed sub-arrays, is used. Numerical simulations and some experimental results for an array of linear sub-arrays with...

Millions of sensors, cameras, meters, and other edge devices are deployed in networks to collect and analyse data. In many cases, such devices are powered only by Energy Harvesting (EH) and have limited energy available to analyse acquired data. When edge infrastructure is available, a device has a choice: to perform analysis locally or offload...

Ethereum is the largest and most prominent smart contract platform. One key property of Ethereum is that once a contract is deployed, it can not be updated anymore. This increases the importance of thoroughly testing the behavior and constraints of the smart contract before deployment. Existing approaches in related work either do not scale or...

Stemming from the convergence of tissue engineering and microfluidics, organ-on-chip (OoC) technology can reproduce in vivo-like dynamic microphysiological environments for tissues in vitro. The possibility afforded by OoC devices of realistic recapitulation of tissue and organ (patho)physiology may hold the key to bridge the current...

We describe the method used to create a dataset of open-source safety-critical software, such as that used for autonomous cars, healthcare, and autonomous aviation, through a systematic and rigorous selection process. The dataset can be used for empirical studies regarding the quality assessment of safety-critical software, its dependencies,...

This paper presents a portable and contactless microfluidic flowmeter based on the Nuclear Magnetic Resonance (NMR) principle, which can measure flow rates up to 2.7 ml/min with \pm 16\ lmin (±0.6% full-scale) error. It consists of a millimeter-size RF coil wound around a microfluidic channel, custom readout electronics and a 0.5 T permanent...

Continuous monitoring of tissue microphysiology is a key enabling feature of the organ-on-chip (OoC) approach for drug screening and disease modeling. Sensing charged species in OoC tissue microenvironments is thereby essential. However, the inherently small (i.e., cm) size of OoC devices poses the challenging requirement to integrate...

We present preliminary recordings on chip of three-dimensional (3D) electric neuronal activity from cultures of cortical neurons derived from human-induced pluripotent stem cells (hiPSCs). The recordings were obtained through 3D microelectrode arrays (MEAs) composed of truncated, 90 μm-high Si micropyramids endowed with multiple, electrically...

In this paper, we present a quadrant sun position sensor microsystem device in a silicon carbide technology that operates in a field-of-view of ±33° and reaches a mean error of 1.9° in this range. This will allow, for the first time, an inherently visible blind sun position sensor in a CMOS compatible technology. Opto-electronic integration of...

Due to its high efficiency, routing based on greedy embeddings of rooted spanning trees is a promising approach for dynamic, large-scale networks with restricted topologies. Friend-to-friend (F2F) overlays, one key application of embedding-based routing, aim to prevent disclosure of their participants to malicious members by restricting...

While most of the work on piezoelectric composites focuses on methods to reduce the dielectric constant of the composite (for better sensor and energy harvesting performance), for haptic feedback and actuator applications the opposite is desirable. We present here a study of the effect of adding a second ceramic phase (BaTiO3 nanoparticles)...

BiFeO<sub>3</sub> is a multiferroic material with the perovskite structure which is promising for use in sensors and transducers. Single phase production of BiFeO<sub>3</sub> remains a challenge, however. In this study, the optimal calcination temperature to obtain close to single phase powder was determined to be 750°C. The sintering...

Titanium aluminide alloys are considered to be attractive materials for aerospace and automotive high-temperature applications due to their high specific strength, creep resistance, and heat resistance. However, their brittleness makes it difficult to manufacture complex-shaped components of these alloys using conventional processes making...

The aim of this study was to determine the influence of heat treatment on the microstructure of single-crystal nickel-based alloy manufactured by selective laser melting with a high-temperature substrate preheating. The change of gamma/gamma prime -phases ratio was established as a result of various heat treatment modes.

A novel fault tolerant control algorithm is proposed in this paper based on model reference reinforcement learning for autonomous surface vehicles subject to sensor faults and model uncertainties. The proposed control scheme is a combination of a model-based control approach and a data-driven method, so it can leverage the advantages of both...

Many control problems are naturally expressed in continuous time. Yet, in Iterative Learning Control of linear systems, sampling the output signal has proven to be a convenient strategy to simplify the learning process while sacrificing only marginally the overall performance. In this context, the control action is similarly discretized through...

Smart grid steady control relies heavily on the communication infrastructure among sensors, actuators, and control systems, which makes it vulnerable to cyber-attacks. Accurate acquisition of dynamic state information is deemed vital for efficient detection of these cyber-attacks on a smart grid. However, several popular state estimation...

The transport sector has been increasing rather than decreasing its CO2 emissions, and its sustainable electrification faces a number of technical and non-technical challenges. This paper investigates these challenges, namely those of the grid load demand modelling, renewables integration, the present infrastructure limitations, and the...
