Fresh and processed berries are a favorite Northwest food. They contain many
beneficial compounds, including vitamins, minerals, phytochemicals, and antioxidants. They also are rich in dietary fiber. Berries of commercial importance for Oregon and Washington include strawberries, raspberries, blueberries, blackberries, and grapes. Less common berry varieties
are gaining in popularity...
The diurnal variability and the environmental conditions that support the moisture resurgence of MJO events observed during the Cooperative Indian Ocean Experiment on Intraseasonal Variability (CINDY)/DYNAMO campaign in October–December 2011 are investigated using in situ observations and the cloud-resolving fully air–ocean–wave Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS). Spectral density and...
Recently there has been a large amount of research into basic human movement as a baseline for robotic motion. Robotic grasping is a challenging problem for a number of reasons. One of which is that it is difficult to accurately know the interaction between the hand and the object, especially...
This paper presents a method of implementing real-time apple detection for closed-loop control to approach apples for grabbing. The approach is to train two known real-time object detection networks–the Faster R-CNN and YOLOv5–on a novel dataset to verify that it is possible to achieve maximum average precision (mAP) above 50\%...
Human-safe Cobots are a popular replacement for industrial robots to automate manufacturing processes such like cutting and deburring that all involve accurate contour following across a workpiece surface while maintaining sufficient tool contact. Cobot arms are less expensive and human-safe but they have larger error motion in comparison when only...
The factors that cause abdominal aortic aneurysm rupture were investigated. Included
in this study were aneurysm volume, thrombus thickness, lumen area, thrombus area,
the average stress acting on the aorta, and the maximum stress on the aorta. The
geometric values were obtained by tracing a series of computerized axial tomography...
Successful pruning relies on accurately identifying the 3D structure of tree branches and leaders. However, this task is arduous in an agricultural setting due to the complexity of scenes, the presence of clutter, and variable weather conditions. This project addresses these challenges by leveraging advancements in 2D image segmentation and...
In-hand manipulations consist of dexterous motions that come easy to humans but still pose a challenge to robotic systems. It is difficult to control finger motions in long complicated sequences due to high DOFs and intricate contact interactions. For such complex motions, in-hand manipulations have generally been broken into a...
Gender issues have recently received increased attention in human robot interaction (HRI). Because robots are becoming part of our homes and daily lives, it is important to understand how different groups of people use them. To the best of our knowledge, almost no research has been done that investigates gender...
3D volume segmentation is a fundamental process in many scientific and medical applications. Producing accurate segmentations, in an efficient way, is challenging, in part due to low imaging data quality (e.g., noise and low image resolution), and ambiguity in the data that can only be resolved with higher-level knowledge of...
