Nature-Inspired Nanotechnology and Sustainability H. Lim Nature-inspired surfaces has received a lot of attentions owing to their potential in diverse applications, including self-cleaning, antireflection, anti-biofouling, anti-icing, water harvesting, anti-fogging, drag reduction, structural color, etc. Natural surfaces such as the lotus leaf, pitcher plant, moth eye, butterfly wings,...
Autonomous driving is a technology that recognizes the external environment and driver's state of the vehicle without driver manipulation, and controls the vehicle based on the recognized information so that it can drive itself to its destination. Autonomous driving technology is regarded as the core...
This seminar presentation aims to provide the review of existing literatures on topology optimization using artificial neural networks (ANNs), and discuss the related future work. Topology optimization is a promising design tool than can find the optimal structural shapes and configurations maximizing a given design goal. Recently, huge...
Energy harvesting technology, which generates the output electric power from ambient, otherwise wasted, energy sources, has been explored toward providing a solution that could ultimately eliminate the replacement cost of the chemical batteries found in wireless sensor nodes. Piezoelectric vibration energy harvesting (PVEH) is recognized as a promising solution for converting vibration energy into usable electricity, because it has high energy density and can be easily miniaturized for use in wireless sensor nodes. Now, a question of fundamental importance arises how to preliminary estimate the output electric power generated by a PVEH device under a given vibration condition and identify the key design parameters to carry out the enhanced output performances. It is thus strongly required to build a highly-predictive model to elucidate the electroelastic behaviors of a PVEH device in an explicit manner. This paper provides deterministic, stochastic, probabilistic modeling approaches for the analysis of PVEH....

Electro-active soft actuators and bio-inspired artificial muscles have received burgeoning interest as essential components in future electronic devices such as soft haptic-feedback systems, human-friendly wearable electronics, and active biomedical devices. However, for more practical applications, important challenging issues including fast response time, ultra-low input power,...
When a water drop is impinged upon superhydrophobic surfaces, various interesting physical phenomena can occur depending on physical structures on the surfaces. In this talk, I will focus on two phenomena during drop impact: the contact time between the drop and the surface and the...
A new high-order projection method for simulating incompressible turbulent flows is presented based on weighted essentially non-oscillatory (WENO) schemes. By the combination of successively higher orders of WENO and CD schemes, the desired order of accuracy (up to seventh order) was achieved without appreciable extra...
에어로졸은 기체 중에 떠 있는 고체 또는 액체의 입자상 물질(particulate matter; PM)을 말한다. 우리가 호흡하는 공기 중에는 수십 μm 이하 크기의 입자상 물질이 부유해 있으므로, 공기는 우리가 일상생활에서 가장 흔히 접할 수 있는 에어로졸의 한 예이다. 공기 중에 떠 있는 10 μm보다 크기가 작은 입자상...
