The transfer of technology from research to structural engineering and construction practice is illustrated using two cases of the implementation of innovative engineering methods and technologies in the renewal and 'upcycling' of existing bridges, namely ...

The design of wings is crucial for tailless Flapping-wing robots (FWRs), as these robots rely exclusively on their wings for lift generation and body control. However, the current methodology for wing design primarily depends on the experience and heuristi ...

The global energy sector stands at a critical juncture, with the imperative shift towards renewable energy sources posing challenges and opportunities for existing infrastructure and societal norms. This thesis explores the multifaceted dynamics of transit ...

The proper orthogonal decomposition (POD) is successfully employed in a variety of projection-based methods for parametric model order reduction (pMOR) of large dynamical systems. It extracts the most energetic modes describing the dynamics of a system fro ...

Biomimetic and bioinspired design is not only a potent resource for roboticists looking to develop robust engineering systems or understand the natural world. It is also a uniquely accessible entry point into science and technology. Every person on Earth c ...

In a MOSFET transistor, the subthreshold swing defines the switching efficiency, and the associated slope factor, or so-called body factor, is a critical parameter in charge-based models. However, in an advanced Fully -Depleted Silicon-On-Insulator (FDSOI) ...

This paper presents a wireless power and data conversion unit, designed to receive power and data via a single inductive link with a focus on applications in implanted biomedical devices. The system provides a reliable power supply for electronic circuits ...

Thermal stability of perovskite materials is an issue impairing the long-term operation of inverted per-ovskite solar cells (PSCs). Herein, the thermal attenuation mechanism of the MAPbI3 films that deposited on two different hole transport layers (HTL), p ...

Majority of the past research on application of machine learning (ML) in earthquake engineering focused on contrasting the predictive performance of different ML algorithms. In contrast, the emphasis of this paper is on the use of data to boost the predict ...

Silicon photonic circuits are rapidly growing in complexity and spreading to new applications. However, programmable circuits consume much power and require active electrical interfaces. For the first time, we demonstrate a nonvolatile photonic MEMS pi-pha ...

Compressor fouling is one of the most prevalent fault modes that contribute to the performance degradation of a gas turbine power plant. Off-line washing is a standard maintenance procedure to recover the fouling degradation, but with washing cost. In this ...

The ever-increasing penetration of renewable energy resources (RESs) in power distribution networks has brought, among others, the challenge of maintaining the grid voltages within the secure region. Employing droop voltage regulators on the RES's inverter ...

Small-scale soft mobile robots are an attractive solution to gain access to hard-to-reach places. We demonstrate a thin (similar to 4 mm) and flexible mobile robot, 8 cm x 9 cm, mass 4 g, that uses 6 electrostatic zipping actuators with hydraulic coupling, ...

Les deltas lacustres sont des systèmes largement anthropisés rendant des services écosystémiques importants à l’Homme et à son environnement. Les travaux de protection contre les crues du siècle passé ont conduit à considérer l’embouchure comme un vecteur ...

Background Spinal cord injury leading to paraplegia affects the mobility and physiological well-being of one in a thousand people. Powered exoskeletons can temporarily restore the ability to walk. Their relevance in daily life is still limited because of l ...

We demonstrate a novel technique of contour-mode suppression of an integrated MEMS-photonic chip up to the first HBAR mode at 17 MHz. The flattened actuation response is critical to the development of compact LiDAR engine or low-noise frequency-agile laser ...

The fluid hammer phenomenon is a devastating incident that can cause substantial damages to the hydraulic systems. If the fluid reaches the vapor pressure due to high pressure gradients, the phenomenon is called column separation. In this study, the overpr ...

Tensors, or multidimensional arrays, are data structures that can naturally represent visual data of multiple dimensions. Inherently able to efficiently capture structured, latent semantic spaces and high-order interactions, tensors have a long history of ...

Despite its simplicity, which makes it the most commonly used bioprinting method today, extrusion-based bioprinting suffers from its inability to reproduce the complex tissue architecture found in organs. Generally, this printing method allows for the disp ...

Electricity production and consumption must be balanced for the electrical grid. However, the rapidly growing intermittent power sources are now challenging the supply-demand balance, leading to large flexibility needs for grid management. The plant integr ...
