Lee, S. (author)This paper focuses on the conception and design of architecture as the work of producing media about buildings and other environmental artifacts. I approach<br/>the questions regarding simplicity and complexity through "interdependence" and "intermodality." I believe the two concepts offer more precise frames of relations and contexts involving...conference paper 2016

Holzheu, Stefanie (author), Lee, S. (author)With the work-in-progress research project ColorTracker we explore color as a formal design tool. This project-based paper describes a novel software application that processes color composition of a place and transcribes the data into three-dimensional geometries for architectural design. The research comprises two parallel trajectories: a...conference paper 2016

Matthes, S (author), Grewe, V. (author), Lee, D (author), Linke, F. (author), Shine, Keith (author), Stromatas, Stavros (author)Trajectory optimisation is one option to reduce air traffic impact on environment. A multidimensional environmental assessment framework is needed to optimize impact on climate, local air quality and noise simultaneously. An interface between flight planning and environmental impact information can be established with environmental cost...conference paper 2016

Zlatanova, S. (author), van Oosterom, P.J.M. (author), Lee, J (author), Li, Ki-Joune (author), Lemmen, C. H. J. (author)Guidance and security in large public buildings such as airports, museums and shopping malls requires much more information that traditional 2D methods offer. Therefore 3D semantically-reach models have been actively investigated with the aim to gather knowledge about availability and accessibility of spaces. Spaces can be unavailable to...conference paper 2016

(author)A design scheme is proposed to evaluate the safety of continuous linear structure i.e. river levee. The scheme is developed to establish a procedure to continuously evaluate the stability failure of embankment during flood runoff by seepage, and to identify locations for reinforcement of river levee. A 20km stretch of a fairly large river...conference paper 2015

Lee, M.J. (author), Sun, P. (author), Charbon, E. (author)We report on the characterization of single-photon avalanche diodes (SPADs) fabricated in standard 140-nm silicon on insulator (SOI) complementary metal-oxide-semiconductor (CMOS) technology. As a methodology for SPAD optimization, a test structure array, called SPAD farm, was realized with several junctions, guard-ring structures, dimensions,...conference paper 2015

Lee, S. (author), Holzheu, S (author)Perceptual Automaton (PA) challenges and disrupts human subjectivity. It attempts to reform architecture that has been for millennia centered on the authority of human subjectivity driven by the whims of architect-personalities. It more crucially interrogates the role of architecture as the material manifestation of human-specific dispositifs...conference paper 2015

(author)In this paper, we propose an approach to autonomously control a quadrotor micro aerial vehicle (MAV). With take-off weight of 50 g and 8-min flight endurance, the MAV platform codenamed KayLion developed by the National University of Singapore (NUS) is able to perform autonomous flight with pre-planned path tracking. The vision-based...conference paper 2014

(author), Boller, K.J. (author)We report on a novel type of laser in which a semiconductor optical amplifier (SOA) receives frequency-selective feedback from a glass-waveguide circuit. The laser we present here is based on InP for operation in the 1.55 µm wavelength range. The Si3N4/SiO2 glass waveguide circuit comprises two sequential high-Q ring resonators. Adiabatic...conference paper 2014
