Assessing the technical condition of earthen constructions is an extremely difficult task due to the fact that the materials, methods and techniques used in construction have been replaced by new materials and installation procedures. Although they have a fairly large share in the existing housing stock, earthen constructions have not benefited from the same interest in the field of construction. This paper proposes a review of the current assessment possibilities applicable to earthen constructions in relation to the current level of knowledge on a local and international level.

Conventional measurement of deflection and twist in full-scale wind turbine blades is predominantly conducted using permanently integrated sensor systems, notably strain gauges and fiber optic sensors. However, these integrated systems are constrained by several critical drawbacks: high cost, laborious installation procedures, and an intrinsic lack of reparability after the blade structure is sealed. To overcome these limitations, we introduce a novel, non-contact monitoring framework that employs a synchronized array of three automotive lidar sensors to measure full-field blade deflections and torsional twist across diverse meteorological environments. Flapwise deflection and pitch obtained from lidar data were validated against measurements from strain gauges at a location 1.4 m from the rotor plane center and against 50 Hz pitch signals from the turbine’s SCADA system. Our results demonstrate the effectiveness of lidar sensors in measuring both parameters along the blade span. The present analysis focuses on flapwise deflection, providing a comparative assessment and introducing a method to correct for the accuracy-degrading effects of boom bending.

Gas-insulated switchgear (GIS) has been widely used in power grid systems. The busbar is a crucial element within a GIS system, responsible for facilitating electrical connections between different GIS components. Any defects during manufacturing or improper installation procedures can lead to busbar misalignment, resulting in abnormal vibrations within the GIS. This study focuses on analyzing the mechanical vibration characteristics of GIS bus misalignment using a simulation model based on the finite element method for a 252kV GIS. When the busbar is misaligned and the conductor experiences an unbalanced force, it undergoes Coulomb forces at double the voltage frequency. Under normal or misaligned conditions, the conductor exhibits forced vibrations at the power frequency of 100Hz. However, when misalignment occurs, there is a coupling effect between electrodynamics and vibrations, causing the shell to display integer frequency vibration components.

Analyzing the interactions of circular RNAs (circRNAs) is a crucial step in understanding their functional impacts. While there are numerous visualization tools available for investigating circRNA interaction networks, these tools are typically limited to known circRNAs from specific databases. Moreover, these existing tools usually require complex installation procedures which can be time-consuming and challenging for users. There is a lack of a user-friendly web application that facilitates interactive exploration and visualization of circRNA interaction networks. CircNetVis is an interactive online web application to enhance the analysis of human/mouse circRNA interactions. The tool allows three different input formats of circRNAs including circRNA IDs from CircBase, circRNA coordinates (chromosome, start position, end position), and circRNA sequences in the FASTA format. It integrates multiple interaction networks for visualization and investigation of the interplay between circRNA, microRNAs, mRNAs and RNA binding proteins. CircNetVis also enables users to interactively explore the interactions of unknown circRNAs which are not reported from previous databases. The tool can generate interactive plots and allows users to save results as output files for offline usage. CircNetVis is implemented as a web application using R-shiny and freely available for academic use at https://www.meb.ki.se/shiny/truvu/CircNetVis/ .

This study proposes a novel approach to surface strain measurement for cylindrical rock specimens subjected to uniaxial compression using distributed fibre optic sensing technology. The capability and accuracy of this approach in measuring the full-field strain distribution of a rock specimen have been verified by a series of uniaxial compressive strength (UCS) tests on cylindrical specimens of aluminium alloy, sandstone, and granite. By analysing the experimental results, this new approach also has the potential of being utilized to detect the potential failure locations and sequence through strain localization zone variations and estimation of the development of crack opening displacement and rock fracturing characteristics during the loading and unloading process. Detailed installation procedures are provided for this study for assistance in the use of this new approach. The boundary issue of fibre measurements is identified, and solved by extending the bonding length of the measuring fibre.

The suction pile well construction technique is increasingly adopted in deepwater drilling projects. The soil–structure interaction mechanism during the penetration and installation of the wellhead suction pile in clay is complex. Given the critical demand for precise installation outcomes in engineering practice, the influence of penetration velocity on installation performance requires significant consideration. Through scale-model experimental methods, various penetration velocities were configured primarily by adjusting suction pump flow rates. The influences of these velocities on penetration resistance, penetration depth, and related metrics were systematically assessed. A case study was conducted based on the engineering parameters of a wellsite in the South China Sea. A theoretical algorithm for WSP penetration resistance was developed and subsequently refined through experimental data. Coefficient optimization was established via theoretical assessment of strain-rate dependency and experimental data calibration. The optimized algorithm demonstrated strong agreement with field measurements, achieving a coefficient of determination (R[sup.2]) exceeding 0.9. Compared to conventional theoretical approaches, it incorporated explicit consideration of penetration velocity. The analysis indicates that in soft clay, the penetration resistance of wellhead suction piles exhibits significant sensitivity to penetration rate, increasing with higher velocities. The influence of penetration rate on penetration depth is relatively weak. This computational approach offers design guidance for installation procedures and enables the implementation of the suction pile well construction mode in the South China Sea.

Wired protocols such as Controller Area Network (CAN) dominate in-vehicle communication today. While reliable, these protocols entail intricate installation procedures. Recent advancements in communication technologies utilizing Electro-Quasistatic Fields (EQS) through conductors have ushered in alternative communication techniques. This work introduces EQS car body communication, recognizing the potential of the car’s chassis as a medium to confine EQS fields. This alternative approach offers a new modality for efficient intra-vehicle wireless communication, addressing power efficiency and physical security concerns. Furthermore, this research demonstrates that a vehicle can be treated as a resonant cavity, providing low-loss, wideband channels for high-speed communication. Theoretical analysis, electromagnetic simulations, and measurements conducted in a consumer-grade vehicle highlight the viability of these new intra-vehicle communication techniques. This fundamentally new approach utilizes different physical modalities, harnessing the car medium itself and opening doors to modalities that have the potential to augment or even replace existing communication in automotive systems. Shreyas Sen and David Yang report the use of a car chassis as a medium to confine electro-quasistatic fields for efficient intra-vehicle wireless communication. The approach addresses both efficiency and physical security concerns.

Graphical Abstract

Floating substructures for offshore wind turbines is a promising solution in order to harness the vast wind potential of deep water sites where bottom-fixed turbines are not feasible. The electrical system of large scale floating offshore wind farms will experience the application of new technologies and installation procedures that likely affect the cost-competitiveness. Thus, in this work, an optimization model based on the particle swarm theory is presented that allows optimizing the collection grid of a floating offshore wind farm. The developed model is applied to a study case consisting of a 500MW floating offshore wind farm located at the Golfe de Fos in the Mediterranean Sea. The resulting layout allows to reduce the total cost of the collection grid by more than 6% and to decrease the energy losses by 8% compared to the actual layout. Besides this, a further study analyzes the effect of a quantity discount with a reduced number of power cable cross sections.

In order to reach a Zero-Energy-consuming building stock, it is necessary to insulate and add renewable energy sources on top of existing building envelopes. Off-site prefabricated modules have been used for covering building facades, but manual on-site installation procedures are still more competitive than prefabricated ones. Renovation with prefabricated modules requires high precision in order to obtain airtight and waterproof conditions. For that, an accurate installation of the anchors on top of the facade is crucial. With current techniques, this is a time-consuming operation. One of the attempts to solve the above-mentioned issue was to place the part of the anchor on top of a building facade with high tolerances and to use an interface to correct the deviations. In previous research, this concept, named Matching Kit, was validated, but improvements needed to be made to make it more competitive. In this paper, thanks to novel algorithms and the use of Point Clouds, an improved version is presented. The results show a reduction in working time and an increase in precision. With this research, the interface is closer to being used in the construction industry.
