Monitoring strain in rolling element bearings using fiber Bragg grating sensors

Using Fiber Bragg Grating (FBG) sensors in rolling element bearings is a novel way of monitoring bearings. During prototype testing, differences between sensor readouts were observed, leading to the research question: “What causes the observed differences in the strain distribution from sensor to sensor in a rolling element bearing equipped with...

A Low-Complexity CMOS Receiver for UWB signals

It is well-known that GPS is a widely used technology for localization in outdoors environments. Nonetheless, such standard fails to provide a practical and accurate solution for localization and ranging applications within indoor environments due to the need of satellites and meter-level accuracy, which is poor for indoor environments. It is in...

Hypergeometric analysis of tiling-array and sequence data: Detection and interpretation of peaks

Probing protein-deoxyribonucleic acid (DNA) is gaining popularity as it sheds light on molecular mechanisms that regulate the expression of genes. Currently, tiling-arrays and next-generation sequencing technology can be used to measure these interactions. Both methods generate a signal over the genome in which contiguous regions of peaks on the...
