Improved fatigue and damage tolerant material design for aerospace industry
Various micro-mechanical and micro-structural influences on fatigue crack growth resistance of the material have been investigated over the years. It is widely recognized that resistance to fatigue crack growth can be ...
Continuously variable mixing-ratio micromixer with elastomer valves
We report a self-contained microfluidic alternate flow injection mixer (AFIM) employing piezoelectrically actuated, PDMS seal-valves to control injection. AFIMs employ pulsatile injection of liquids to enhance interface ...
Micro throttle pump employing displacement amplification in an elastomeric substrate
We report a micro throttle pump (MTP) with enhanced throttling resulting from beneficial deformation of its elastomer substrate. In the MTP reported, this has doubled the effective deflection of the piezo electric (PZT) ...
An investigation of the self-propagating high-temperature synthesis of Ti(Si,Al)
The self-propagating high-temperature synthesis (SPS) of TiSi and T Si,AL) powders was investigated. Elemental powders of titanium, silicon and aluminum were used for the synthesis. The sample powders were investigated by ...
On the use of decoupled and adapted Gaussian mixture models for open-set speaker identification
(Office for Official Publications of the European Communities, 2005)
This paper presents a comparative analysis of the performance of decoupled and adapted Gaussian mixture models (GMMs) for open-set, text-independent speaker identification (OSTISI). The analysis is based on a set of ...
On the estimation of rotational frequency response functions
(KATHOLIEKE UNIV LEUVEN, DEPT WERKTUIGKUNDE, 2005)
Rotational receptances can perform an important role when predicting the dynamic behaviour both in theoretical and experimental models, especially when a modification includes a rotational inertia or a rotational stiffness. ...
