Summary: The conventional design process of modular high-rise residential buildings heavily depends on designers' experience, which raises concerns about design efficiency and quality. This paper introduces a genetic algorithm to automatically generate layouts for such buildings. The approach includes two stages: one for modular flat layout design and another for traffic core layout design. Computer-aided design (CAD) drawings are automatically generated using the Autodesk CAD application programming interface, based on the information acquired from the proposed approach. A website is developed for designers' interaction, and two examples are provided to demonstrate the effectiveness of the approach.

Summary: The application of reduced activation ferritic/martensitic (RAFM) steels in future fusion reactors requires an understanding of their mechanical properties under relevant operational conditions. Experimental and computational methods are used to simplify the characterization of irradiated materials, with ion irradiation considered as a possible alternative to high-flux neutron irradiation damage. Nanoindentation techniques and crystal plasticity finite element method (CPFEM) were used to study BCC iron, the basis material for ferritic steels, and analyze its mechanical behavior.

Summary: The government of Korea has introduced a green remodeling policy to improve building energy efficiency and achieve zero energy goals by 2030. However, the current energy simulations in the design stage do not account for realistic airtightness performances. This study conducted experimental analysis on airtightness in residential buildings in Korea and found significant improvements in recently built residential buildings compared to those built 30 years ago. The findings provide valuable insights for designers and engineers to develop more accurate residential energy models for code compliance.

Summary: Many cities use minimum off-street residential parking requirements to address the parking demand associated with new residential development, with variations such as reduced or eliminated minimums and/or maximum parking requirements for more active management. The study on parking overlays in Melbourne found that car ownership is generally lower in affected areas and highlighted the importance of public transport service quality, car parking requirements, and demographics in influencing car ownership. The results suggest that residential off-street parking requirements could be further reduced in Melbourne to better manage parking demand.

Summary: This study investigates the process of methane hydrate formation and dissociation in a small-scale controlled environment with porous sediment. It addresses the lack of information about the intrinsic properties of these processes, such as memory effect and anomalous self-preservation, in a lab-scale apparatus. Experimental results demonstrate the improvement of the process during the initial nucleation phase through the memory effect and divide the formation process into two distinct steps.

Summary: This study investigates the formation of carbon dioxide hydrates in natural silica-based porous medium and fresh water through experiments. The results show that the persistence of the memory effect is weak at temperatures slightly above 25 degrees C and ice formation competes with hydrates. By evaluating thermodynamic parameters, gas consumption, and rate constant, some conclusions about the differences between measured and real equilibrium conditions for the system are drawn.
