- Mobile security,
- Speech processing, and
- Protective materials
Mobile phones are an important part of our daily lives. Besides the default mobile applications, users would usually install many 3rd party applications. There are chances that some applications may be malicious, have unknown backdoors in them or have unpatched security weaknesses in the applications.
We conduct research and development on effective techniques to find weak code in mobile applications and operating systems, and on ways to enhance software quality for mobile applications; and analysis of weak or malicious components in mobile phone platforms and recommendations for mitigation.
The project currently focuses on Apple’s iOS – which is used on the iPhone and other Apple devices – but work may be expanded to other mobile platforms.
The TL@NTU Speech Recognition team aims to be a premier R&D team to provide customized, relevant speech processing solutions. The programme was initiated to conduct R&D in speech recognition for languages with poor language resource support, e.g. lack of good annotated speech corpus. The team also explores related speech technologies such as speech algorithms, speaker profiling and language identification. The team’s current research capability includes speech enhancement, domain adaptation, conversational code-switch, speech recognition in noisy conditions, and speaker verification.

The protective materials team focuses on the development of advanced protection technology, through the use of ballistic testing, mechanical material characterization, hydrocode simulation, defeat mechanisms study and novel materials development. In Ma Jan High Speed Dynamics Laboratory, the research team carries out experimental studies using the Two-stage Gas Launcher, Single-stage Gas Launcher and the Split Hopkinson Pressure Bar. We have simulation capability for protective materials subject to ballistic threats using LS-DYNA and AUTODYN. Our research also closely links to material synthesis research for light and effective protective materials.
The research team has established experimental capability to launch various types of projectiles at high impact velocity. The team is capable of developing metal/ polymer bilayer covers which significantly enhanced the ballistic performance of ceramic modules, performing studies on metallic module’s ballistic performance and defeat mechanisms e.g. dwell and interface defeat, through ballistic experiment and hydrocode simulation. The team has expertise to develop high performance Spinel transparent armour module and has produced shape memory ceramic particles which demonstrate superelastic properties with energy dissipation up to 50MJ/m3.
