UNLABELLED PREMISE OF THE STUDY Digital microscopic pollen images are being generated with increasing speed and volume, producing opportunities to develop new computational methods that increase the consistency and efficiency of pollen analysis and provide the palynological community a computational framework for information sharing and knowledge(More)
This preliminary study, as a part of a broader study about the medical image use by experts and novices, examines the differences in image describing behavior between these two categories of users. Eye tracking technique was used to capture the image users' eye movement on the Area of Interests (AOIs). This study found that a domain expert was capable of(More)
An efficient and robust medical-image indexing procedure should be user-oriented. It is essential to index the images at the right level of description and ensure that the indexed levels match the user’s interest level. This study examines 240medical-imagedescriptionsproduced by three different groups of medical-image users (novices, intermediates, and(More)
To make a biological information system valuable for the life sciences community, data analytics have to provide explainable results that can demonstrate the linkages between measurable features and biological meaning of interest. Neither traditional classification nor information retrieval methods are sufficient for biomedical applications if such linkages(More)
Identifying repetitive gene sequences occurring within DNA sequences that span a collection of species is a challenge that is conceptually simple yet computationally challenging. Biological research suggests that certain regions within genomic sequences may be unchanged for hundreds of millions of years; understanding and identifying these highly preserved(More)
The vanadium redox flow battery (VRB) is a nonlinear system with unknown dynamics and disturbances. The flowrate of the electrolyte is an important control mechanism in the operation of a VRB system. Too low or too high flowrate is unfavorable for the safety and performance of VRB.This paper presents a neural network predictive control scheme to enhance the(More)
Research has shown that visual information of multimedia is critical in highly-skilled application, such as biomedicine and life sciences, and a certain visual reasoning process is essential for meaningful search in a timely manner. Relevant image characteristics are learned and verified with accumulated experiences during the reasoning processes. However,(More)
