Revolutionising the 4D BIM Process in Modular Construction
Given the heightened importance of revolutionising 4D BIM-based construction scheduling in modular construction, it has become vital to explore how 4D-BIM could be integrated with the lean concept. Lean-integrated 4D BIM in modular construction have different considerations when compared with component/object-based scheduling. A lean-integrated 4D BIM process model was developed from the analysis and it was validated using an interactive workshop with eight participants from two UK construction companies and two modular construction manufacturers.

Artificial Intelligence Applied to Variable Renewable Energy Systems
The development directions of artificial intelligence (AI) for variable renewable energy (VRE) are of paramount importance in navigating the challenges and optimizing the utilization of renewable energy sources. As the global energy landscape undergoes a transformative shift towards increased reliance on VRE, AI offers strategic avenues to enhance the efficiency, dependability, and eco-sustainability of these systems. The integration of AI methodologies in VRE management addresses complexities related to data quality, model transparency, and system optimization. The burgeoning digitalization of energy supplies, coupled with the dynamic nature of VRE, necessitates innovative solutions to harness the full potential of renewable sources. AI has the potential to contribute significantly to overcoming inherent challenges, not only paving the way for improved energy forecasting, distribution, and system control but also through fostering a more sustainable and resilient energy paradigm in line with the demands of a rapidly evolving global climate and energy landscape.

Indoor Electronic Travel Aid for Visually Impaired Individuals
Most navigation aids for visually impaired individuals require users to pay close attention and actively understand the instructions or feedback of guidance, which impose considerable cognitive loads in long-term usage. The “Aerial Guide Dog”, a helium balloon aerostat drone designed for indoor guidance, which leverages gentle tugs in real time for directional guidance, ensuring a seamless and intuitive guiding experience. The introduced Aerial Guide Dog has been evaluated in terms of directional guidance and path following in the pilot study, focusing on assessing its accuracy in orientation and the overall performance in navigation.

Byproduct Oxygen for Green Hydrogen Electrolysis
Water electrolysis for hydrogen production with renewable electricity is regularly studied. The inclusion of byproduct electrolytic oxygen capture and sale is of interest for parallel decarbonisation efforts elsewhere in the industry and could contribute to reducing green hydrogen costs. A deterministic hydrogen electrolysis system model is constructed to compare oxygen inclusion/exclusion scenarios. This uses wind and solar-PV electricity generation timeseries, a power-dependent electrolysis model to determine the energy efficiency of gas yield, and power allocation for gas post-processing energy within each hourly timestep. This maintains a fully renewable (and therefore low/zero carbon) electricity source for electrolysis and gas post-processing. The model is validated (excluding oxygen) against an existing low-cost GW-scale solar-hydrogen production scenario and an existing hydrogen production costs study with offshore wind generation at the multi-MW scale. For both comparisons, oxygen inclusion is then evaluated to demonstrate both the benefits and drawbacks of capture and utilisation, for different scenario conditions, and high parameter sensitivity can be seen regarding the price of renewable electricity.

Advances in Non-Invasive Neuromodulation: Closed-Loop Vagus Nerve Stimulation
Transcutaneous auricular vagus nerve stimulation (taVNS) is a non-invasive neuromodulation therapy that eliminates the need for internal device implantation, presenting as a favorable therapeutic option. This method relies on electrical surface stimulation, bypassing the need for surgical procedures.

Quantifying the Complexity of the Autonomous Vehicles Environment
One of the challenges that autonomous vehicles (AVs) face is the large amount of data inundating the onboard computer from its sensors, which is beyond the real-time processing capabilities of current AV models. The onboard computer equipped by the AVs, which is required to operate in real- time, has the onus of perceiving the environment surrounding the AV, processing the incoming information, and making the most apt decisions to ensure the safe operations of the ego vehicle.

Splitter-Island on Pedestrian Safety at Roundabout
Traffic accident statistics have traditionally been used to assess traffic safety. This method has severe limitations when used to investigate the impact of a particular feature of traffic facilities on safety at a microscopic level. Most previous research on surrogate safety measures (SSMs) had, on the other hand, focused on studying the safety of traffic operation conditions.

Biochar-Based Materials for Wastewater Treatment
Biochar is an important, interesting, low-cost material with various agricultural, industrial, and scientific applications. Biochar is a name given to vegetable-derived charcoal, which can be used as an agent to improve soil and water quality. This carbon-rich substance can be produced by the carbonization of biomass residues (e.g., wood, dung, manure, or leaves) in thermal conversion processes, such as pyrolysis, torrefaction, and hydrothermal carbonization (HTC). Among them, pyrolysis is the most common process to obtain biochar under anaerobic conditions and high temperatures. In addition, heat, syngas, liquid fuels, and pyroligneous acid (wood vinegar) are also generated during this process.
