How Students Coordinate The Use Of Representations And Explanations In Introductory Genetics Learning
-
The past, present and future of genome-wide re-annotation
We define the process of annotating a previously annotated genome sequence as 're-annotation', and examine the strengths and weaknesses of current manual and automatic genome-wide re-annotation approaches.

The Radiometry of Multiple Images
We introduce a methodology for radiometric reconstruction, the simultaneous recovery of multiple illuminants and surface albedoes from multiple views, assuming that the geometry of the scene and of the cameras…

Lightweight solutions for user interfaces over the WWW
We present some lightweight tools that have been essential in producing applications with complex interactive interfaces.

Putting the ‘Learning’ in Adventure Learning: Design Principles for Technology-supported Classroom Inquiry
-
Self-consistency, Stereo, MDL, and Change detection
Our main goal is to predict the accuracy of an output element of an existing stereo algorithm

Constrained optimization based control of real time large-scale systems: airjet object movement system
This paper demonstrates that hyper-redundant systems are capable of system self-identification, and that constrained optimization can effectively solve problems associated with control of many-element systems.

Multispeaker Speech Activity Detection for the ICSI Meeting Recorder
We have developed a more sophisticated approach for multichannel speech activity detection using a simple hidden Markov model (HMM).

Capturing Analytic Thought
We are developing a new methodology that retains the ease of use, the familiarity, and (some of) the free-form nature of informal methods, while benefiting from the rigor, structure, and…

Modeling Word Durations
We describe a new method of modeling duration at word level. These duration models are easily trained from the acoustic training data and can be used to rescore N-best lists…
