Transcript of TL Siaw | Portfolio

Industrial Design

2002 − 2006
Computer Science

Bachelor & Master
2006 − 2012
Job-related work

2012 − 2016

Digital designs
Design of digital camera for teenagers
Futuristic security camera
Mobile phone evolution
Door with built-in cupboards
Toy caterpillar
Luggage cart for hikers (group work)
Technical designs
Design of solar-powered bag
Bachelor Final Project (2005)

Link to Bachelor thesis (Dutch):
Extracting rip currents from shoreline
images using spatial segmentation
(Individual) Research Assignment
GPSI minor (ITC) – January 2009 till March 2009
Algorithm design, implementation & evaluation
ICT tools: Python & wxPython

Short description:
Implement an algorithm to extract rip currents from panoramic shoreline images. Goal is to automate the detection process of rip currents, since this is still being done manually by experts.
HeaDSET, software for aiding brain operations
Design Project (group work)
Bachelor CS – September 2008 till February 2009
Softwaretool design & implementation
ICT tools: Python & wxPython

Short description:
Design and implement a tool to aid brain surgeons to plan, record and play back operations on removing brain tumors. The tool uses 3D visualization of the patient's head.
The effects of presentation and
content related factors on
persuasion in risk communication
Bachelor Paper (Twente Student Conference on IT)
Bachelor CS – February 2009 till June 2009
Scientific literature study

Short description:
Perform a literature study to investigate what influence certain presentation modalities (as numbers, graphs, text and imagery) and content related modalities (as statistical data and narratives) have on persuading people about risks.
Graph Layout
Traineeship (at Novulo, Enschede)
Master CS – August 2010 till November 2010
Algorithm design & implementation
ICT tools: Java & JGraph

Short description:
Design and implement an algorithm to display UML diagrams more user friendly and provide a better overview of the diagrams to the user. Goal is to improve and provide an automatic function to do this, since this function is not performing correcly.
Saturation for LTSmin
Final Project
Master CS – July 2011 till February 2012
Algorithm design, implementation & evaluation
ICT tool: C

Short description:
Adjust and implement a new state space generation algorithm from G. Ciardo for the LTSmin toolset (developed by the FMT research group). The algorithm calculates all the reachable states of a (system) model from an initial state and stores them in a graph-like data structure, called MDD.
From a chaotic to an orderly view
Simple traffic lights model with 6 reachable states and how each state is stored in an MDD (path from root node to T(rue) node)

Personal work

2006 − 2016
Christmas cards
Other cards
Graph Auto Layout Function
Traineeship (at BiZZdesign, Enschede)
September 2012 till November 2012
Algorithm design & implementation
ICT tools: Toolspecific language (in Architect tool)

Short description:
Improve the Auto Layout Function for graphs of the Architect Tool by implementing a post-processing algorithm which structures the graph layout. The algorithm puts the nodes in a grid and then it aligns the edges in a straight way.
From a chaotic to an orderly view
(other approach compared to previous traineeship at Novulo)
