Quantitative Analysis of Illicit Drug Residues from Wastewater using Surface-enhanced Raman Scattering

Creator:

Zhang, Boxin

Abstract:

Detection of illicit drug residues from wastewater provides a new route toward community level assessment of drug abuse that is critical to public health. However, traditional chemistry analytical tools such as liquid chromatography in tandem with mass spectrometry cannot meet the large-scale testing requirement in terms of cost, throughput, and...

Masters Thesis
Probabilistic models for quality control in environmental sensor networks

Creator:

Dereszynski, Ethan W.

Abstract:

Networks of distributed, remote sensors are providing ecological scientists with a view of our environment that is unprecedented in detail. However, these networks are subject to harsh conditions, which lead to malfunctions in individual sensors and failures in network communications. This behavior manifests as corrupt or missing measurements in the...

Dissertation
A probabilistic model for anomaly detection in remote sensor streams

Creator:

Dereszynski, Ethan W.

Abstract:

Remote sensors are becoming the standard for observing and recording ecological data in the field. Such sensors can record data at fine temporal resolutions, and they can operate under extreme conditions prohibitive to human access. Unfortunately, sensor data streams exhibit many kinds of errors ranging from corrupt communications to partial...
