Wind energy is an increasingly viable solution for sustainable power generation, particularly in developing regions with high wind potential. This paper presents a comprehensive analysis of the wind power and energy output estimation for the Sela Dingay wind farm, a candidate site in Ethiopia. The study utilizes measured wind speed data at 50 meters and interpolates it to different hub heights (91
In this work, we introduce novel techniques for adapting the SCA-LDPC framework to NTRU-style Key Encapsulation Mechanisms (KEMs). Our approach significantly reduces the required measurements compared to prior analyses under similar oracle noise, validated through extensive simulations, and shows robustness against decision errors in the constructed oracle. Furthermore, we present the first docume
While a naive algorithm for multiplying two 2 × 2 matrices requires eight multiplications and four additions, Strassen showed how to compute the same matrix product using seven multiplications and 18 additions. Winograd reduced the number of additions to 15, which was assumed to be optimal. However, by introducing a change of basis, Karstadt and Schwartz showed how to lower the number of additions
Reusing building products is a feasible strategy for the construction and real estate industry to mitigate its climate impact. Sustainable reuse must be executed with quality assurance and defined responsibilities to encourage clients and avoid suboptimal outcomes. Despite the growing need to quality-assure reused products, there is limited research, particularly from an industry perspective. Prev

Here we report on reactive Large Eddy Simulations (LES) of flow and combustion in the US Air Force Research Laboratory Research Cell 19 cavity-based scramjet combustor. This case involves combustion of ethylene (C2H4) injected into a cavity from its slanted trailing edge. It has previously been studied experimentally with multiple techniques including particle image velocimetry, shadowgrapy, OH pl
The present study investigates the thermoacoustic instability for triangular bluff-body stabilized flames using high fidelity Large Eddy Simulations with finite-rate chemistry. The study includes premixed propane-air combustion, studying the triggering of the thermoacoustic instability for different parameters such as, incoming turbulence intensity, inlet velocity and temperature, and equivalence
Forest Canopy Height (FCH) is one of the key variables for understanding forest structure distribution and growth. Remotely sensed data such as the NASA Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) ATL08 provides accurate FCH measurements; however, its point-based nature limits spatial continuity. This study addresses the challenge by generating a continuous FCH map over the West Usambara
In the past decades, the number of research work explaining the load transfer mechanism of moment connections has increased due to their advantages of energy dissipation capacity and improved load distribution. The use of bolts in slotted-in plate moment connections is a common practice in timber construction. However, the design and application guidelines are still limited and leading to results
This paper addresses the path-tracking problem of time-optimal trajectories under model uncertainties, by proposing a real-time predictive scaling algorithm. The algorithm is formulated as a convex optimization problem, designed to balance the trade-off between improving feasibility and time optimality of a trajectory. The predicted trajectory is scaled based on the presence of path segments that
This study presents a digital solution for inducing visually-induced motion sickness (VIMS) using a head-mounted display (HMD) in a virtual environment. By digitally replicating off vertical axis rotation by adopting the Epley Omniax Chair, we induce sensory conflicts between the visual and vestibular systems through rotational vection, alongside optokinetic stimulation inspired by the Optoki-neti
Supersonic combustion is a critical area of research for advancing high-speed flight technologies, particularly for the development of scramjet engines for hypersonic vehicles. This study employs Finite Rate Chemistry (FRC) Large Eddy Simulation (LES) together with different experimental techniques to study the supersonic flow and thermochemical processes in the Small Scale Flight Experiment (SSFE
Distributed massive multiple-input multiple-output (MIMO) communication is envisioned as one of the key paradigms of future MIMO systems. To investigate non-wide-sense stationarities (non-WSSs) in distributed massive MIMO channels, this paper first presents an indoor channel measurement campaign, where distributed arrays with a total of 128 elements were implemented. Then relying on the correlatio
Testing printed circuit boards (PCBs) is an important part of the production process. The development and generation of tests is however a labour-intensive process that requires expertise and deep understanding of the PCB. As generative Artificial Intelligence in form of Large Language Models (LLMs) as evolved, we explore its use for PCBs test generation. The main question is: for a given design s
Radio-frequency simultaneous localization and mapping (RF-SLAM) methods jointly infer the position of mobile transmitters and receivers in wireless networks, together with a geometric map of the propagation environment. An inferred map of specular surfaces can be used to exploit non-line-of-sight components of the multipath channel to increase robustness, bypass obstructions, and improve overall c
An accurate description of the wireless channel is essential to the development of modern wireless systems. In order to mathematically model the propagation channel, one important prior step often done is high-resolution parameter estimation. The estimation accuracy of this step has a significant impact on how well the channel models can represent reality. In this paper, we address this by improvi
