In today's era of large-scale simulations and experiments, the demand for efficient computational models has seen significant growth. Surrogate modeling, a technique used to approximate expensive models or simulations with simpler, data-driven models, plays an essential role in this arena. This presentation focuses on the most recent...
The KSLV-II (Korea Space Launch Vehicle-II) Nuri launched on June 21st, 2022. The Nuri vehicle used kerosene as fuel and the cryogenic liquid oxygen as oxidant. The management cryogenic liquid oxygen is required during the development of the NURI. Such as leveling the liquid oxygen tank, natural circulation...
In this talk, I will present nanoscale transport phenomena driven by solute or temperature difference. Firstly, I will demonstrate that the liquid flow can be generated by various types of solutes within nanochannels. The underlying mechanism for interfacially driven flow is closely associated with the molecular interactions between...
Key Words: 이동 로봇, 다중 이동방식 Abstract Numerous mobile robots specialize in one form of locomotion, whereas very few robots can perform complex locomotion tasks that combine multiple locomotion methods. A robot equipped with multiple locomotion mechanisms can not only traverse challenging environments where a single-modal locomotion...
Open-source autonomous driving software and its research challenges Recently, an open-source autonomous driving stack called Autoware has spread widely, and the number of Autoware-enabled vehicles is increasing. Autoware is currently being used in more than 30 vehicles in more than 20 countries by more than 100...
This presentation explores bioaerosols, defined as airborne biological particulate matter containing a variety of allergens such as viruses, bacteria, fungi, pollen, house dust mites, and dander. Bioaerosols can cause a variety of infectious and environmental diseases, including atopic dermatitis, opportunistic infections, SARS, novel influenza, and...
Abstract: Over the course of 3.5 billion years of evolution, living organisms have developed numerous functional structures. Notable examples include the superhydrophobic surfaces of micro/nano-structured leaves, the non-reflective surfaces of moth eyes, and the highly sensitive sensory organs of spiders. Understanding and mimicking these functional...
With the recent emergence of future mobility developments such as Urban Air Mobility (UAM), there has been an increasing interest in the development of materials suitable for these advancements. What might the specific requirements be for materials used in future mobility? Firstly, lightweight materials will be...
When shape optimization of engineering objects is conducted in the aerodynamic prospective, it is necessary to examine objects’ performance at various designs. One of the most widely used shape design methods in this purpose is to parameterize the given shape (frequently called the baseline design or...
Recent developments in multi-scale and non-linear topology optimization problems By Ole Sigmund, Villum Investigator, Dept. of Mechanical Engineering, Technical University of Denmark Topology optimization was introduced as a multi-scale approach in the seminal paper by Bendsøe and Kikuchi from 1988. However, simpler isotropic density interpolation schemes soon substituted the original homogenization-based approach. With advances in additive manufacturing technologies that may realize complex lattice and infill structures, needs...
