This work is based on the premise that the interactional construction of meaning is as important in online settings as it is face-to-face, especially in collaborative learning. Most studies of online learning use quantitative methods that assign meaning to contributions in isolation and aggregate over many sessions, obscuring the situated procedures by which participants accomplish learning thr...

Interactive Internet Applications that rely on sequential streams for lossless data exchange often use retransmission protocols (e.g. TCP) for reliability and the guarantee of sequential data ordering. More so than for bulk file transfer or media delivery, lossless sequential streaming poses an even greater challenge for the common problem cases of retransmission protocols, such as lossy links ...

A method is described for increasing the production of H2 from glucose or lactate by Selenomonas ruminantium by sequential transfers in media containing pregrown Methanobacterium ruminantium. The methanogen uses the H2 formed by the selenomonad to reduce CO2 to CH4. Analysis of fermentation products from glucose showed that lactate was the major product formed from glucose by S. ruminantium alo...

Avibacterium paragallinarum is Gram-negative bacteria that cause infectious coryza (IC), an acute respiratory disease of chickens. Despite vaccination of Layer and breeder farms of Iran against IC, they are still experiencing the disease clinically and there is no knowledge of serotypes prevalence of this bacterium in this country. This study designed to determine serovar identity by molecular ...

Social media data associated with geographic location and time information reflect people footprint in real world. Abundance of geo-referenced content represents a massive opportunity to understanding of human geographic mobility behaviors. Most trajectory mining research from geo-enabled social media data focus on spatial geometric features. Integrating trajectory analysis with semantic inform...

In this paper we study the thermal effective behaviour for 3D multiphase composite material consisting of three isotropic phases which are the matrix, the inclusions and the coating media. For this purpose we use an accelerated FFT-based scheme initially proposed in Eyre and Milton (1999) to evaluate the thermal conductivity tensor. Matrix and spherical inclusions media are polymers with simila...

Despite increasing interest in leveraging the wealth of online social media data to support data-based decision making, much work in this direction has focused on tasks with straightforward “labeling” decisions. A much richer class of tasks can benefit from the power of sequential decision making. However, supporting such tasks requires learning some form of action or decision models from unstr...
