Recent developments in multi-scale and non-linear topology optimization problems

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...

Evaluation methods, standards, and specifications for additive manufacturing

After the news about the disease of teachers related to additive manufacturing in Korea, there has been a lot of discussion on how to evaluate the stability of additive manufacturing. To solve this problem, all relevant government departments jointly announced measures. The announced measures include...

3D Spatial Perception for Robotics

The technology to accurately perceive and estimate 6-DoF ego-motion and surrounding environments based on RGB and depth images is called visual SLAM (Simultaneous Localization and Mapping), which is one of the fundamental technologies for autonomous driving of unmanned platforms such as unmanned vehicles and drones....

Entrepreneurship and Law

Entrepreneurship and Law -Subtitle: Things Startups Must Do, Should Do, and Should Not Do This lecture explores what startups must do, should do, and should not do from a legal perspective during the preparation for entrepreneurship,  incorporation, and the process of running a corporation. More specifically, it covers topics such as determining the legal form of a business entity, matters to be determined when establishing a corporation, an overview of the structure of a Corporation, partnership agreements, legal obligations enforced by legislation depending on the industry such as e-commerce...

Technology, into the Market

Engineering is not simply a study to solve our curiosity, but it is meaningful only when someone actually uses its outcome. In this presentation, we will take a look at the process that the technology developed in academia actually goes through to enter the market...

Accurate prediction of thermophysical properties of supercritical hydrocarbon aviation fuels and its application

ACCURATE PREDICTION OF THERMOPHYSICAL PROPERTIES OF SUPERCRITICAL HYDROCARBON AVIATION FUELS AND ITS APPLICATION Hyung Ju Lee, Ph.D. Assistant Professor, Department of Mechanical Engineering, Pukyong National University ABSTRACT Scramjet engines have been studied worldwide for decades for applications in hypersonic flight over the Mach 5 within the atmosphere, as they...

Applications of Additive Manufacturing to Mobility Industries

This lecture aims to explore the potential impact of 3D printing on the automotive and construction fields. With the rapid development of 3D printing technology, it has become increasingly feasible to create complex, customized parts and structures that were previously impossible or prohibitively expensive using...

Principles of magnetic bearings and their applications to industrial machines

Active magnetic bearings are a mechatronic device which utilizes magnetic forces to levitate rotating shaft without mechanical contact. They enable higher speeds because of reduced losses. Also, the dynamics of the system can be adjusted by modifying the control law of magnetic bearings. In this...
