In this paper we present an improved method for capturing information presented on a whiteboard in the context of lecture capture. The method produces better results than any method currently used and builds on methods available within the field of single-frame whiteboard enhancement. We present new techniques for both removing the lecturer from in front of the whiteboard and enhancing whiteboard...
We created an Eclipse plug-in called FrenchPress that offers students feedback on their Java programming style. It is designed not for novices but for students taking their second or third Java course. Advanced beginner students know enough to produce a program with the desired input/output behavior, but fail to understand it could still be poorly written. Large class sizes in introductory courses...
The application of radiation scattering methods to investigate the phase separation kinetics of block copolymers is discussed from the view point of the random phase approximation. Experimental data for a series of equilibrium and time0-resolved experiments have been obtained using small-angle neutron scattering (SANS). Values of the interaction parameter and the Onsager coefficient (characterising...
The theory and essential principles of small angle neutron scattering are presented together with their evolution to expressions useable in the interpretation of experimental data. The two components to the scattering law, single particle scattering and interference function scattering are identified and some classical expressions for the scattering of single particles are reviewed. Instrumental aspects...
The new millennium brought multiple discoveries of epigenetic events regulating the chromatin structure of normal and cancerous cells. Such renewed enthusiasm for chromatin studies was prompted by the development of new technologies and novel ideas that helped discover the “histone code.” It is now clear that posttranslational modifications of histone tails and insertion of histone variants regulate...
Lecture recording is not a new concept nor is high-resolution recording of multimedia presentations that include computer and whiteboard material. We describe a novel portable lecture capture system that captures not only computer content and video as do most modern lecture capture systems but also captures content from whiteboards. The white-board material is captured at high resolution and processed...
This paper presents three case studies of risk-based standards from Great Britain: the pre-liberalisation generation planning standard, the present method for setting operational reserve requirements, and the transmission network planning standard. These illustrate a number of key issues in developing planning and operational standards for wind, including: the benefits of risk-based standards in adapting...
Social and biological systems consist of many levels, typically hierarchically arranged, with different mechanisms and rules for organizing information and decision-making at each level. Rules governing individual acts for cooperative activities, for example, are quite different from those of a government that enforces laws for businesses. These different rules are distinctive to their own level....
Understanding the dynamics of network evolution rests in part on the representation chosen to characterize the evolutionary process. We offer a simple, three-parameter representation based on subgraphs that capture three important properties of social networks: leadership, team alignment or bonding among members, and diversity of expertise. When plotted on this representation, the evolution of a typical...
Natural Intelligence is based not only on conscious procedural and declarative knowledge, but also on knowledge that is inferred from observing the actions of others. This knowledge is tacit, in that the process of its acquisition remains unspecified. However, tacit knowledge is an accepted guide of behavior, especially in unfamiliar contexts. In situations where knowledge is lacking, animals act...
This paper studies the architectural trade-offs found in a novel ATM packet switch that offers several benefits for applications based on free-space digital optics. The architecture is based on a banyan network, but it uses a combination of deflection routing and output buffering to solve the contention resolution problem. It also makes novel use of chutes to remove packets from the banyan network...
