An application of regression tree methodology in freeway travel time estimation using speed as a proxy

Creator:

Wang, Lijuan

Abstract:

Accurate freeway travel time estimation is of increasing importance for the travelers’ information and route guidance system. A non-parametric statistical methodology known as regression trees is deployed in this research for dynamically and accurately estimating freeway travel times for the I5-I205 loop in the Portland Metro area of Oregon using...

The design of an aquatic insect imaging device as part of a system to automate insect classification for biomonitoring

Creator:

Sarpola, Matt J.

Abstract:

Population counts of aquatic insects are a valuable tool for monitoring the water quality of rivers and streams. However, the handling of samples in the lab for species identification is time consuming. An aquatic insect imaging device was designed as part of a system to automate aquatic insect classification and...

Physical activity recognition of free-living data using change-point detection algorithms and hidden Markov models

Creator:

Anderson, Michael M.

Abstract:

Physical activity recognition using accelerometer data is a rapidly emerging ﬁeld with many real-world applications. Much of the previous work in this area has assumed that the accelerometer data has already been segmented into pure activities, and the activity recognition task has been to classify these segments. In reality, activity...
