Wearable sensor data fusion for human stress estimation
Offer N°: SL-DRT-16-0883
Stress is a normal reaction to external constraints. A reaction too much important or lasting too long can lead to physical or mental disorders. Measuring stress level of a person wearing sensors could help to detect too high or long stress levels and act consequently in order to prevent the emergence of associated troubles. Recent works show that it is possible to link non-invasive physiological measures with several stress levels induced in laboratory conditions.
Proposal of a UNUM arithmetic calculation unit and its application to scientific computing
Offer N°: SL-DRT-16-0568
UNUM is a very recent representation (2010) for floating point numbers, which outperforms the classical IEEE 754 representation for accuracy, and accelerates convergence for iterative calculations.
Multi-scale impact of direct bonding on the internal stresses and strains
Offer N°: SL-DRT-16-0557
Direct bonding is increasingly used for the development of very small structures (MEMS, NEMS, ...) and for applications requiring a very precise alignment of the bonded surfaces (3D integration). However, the internal deformations potentially induced by the bonding can disturb the alignment of the two wafers at the scale of each component. Internal stresses that will result can also disrupt the operation of very small devices and deteriorate their performance.
Multimodal lensless microscopy for biomedical applications
Offer N°: SL-DRT-16-0512
The development of miniaturized and high performance CMOS-sensors allowed the emergence of new imaging methods, called “on-chip” microscopy. These methods, generally based on shadow imaging or in-line holography, use simplified and robust instrumentation, and allow to address applications in "point of care" or in resource limited or hostile environments.
