Matroid theory was first formalized in 1935 by Whitney [5] who introduced the notion as an attempt to study the properties of vector spaces in an abstract manner. Since then, matroids have proven to have numerous applications in a wide variety of fields including combinatorics and graph theory. Today we will briefly survey matroid representation and then discuss some problems in matroid optimiz...

In the design of recent systems, I have advanced techniques that position graphic synthesis methods in the context of solo, improvisational performance. Here, the primary interfaces for musical action are prepared works on paper, scanned by digital video cameras which in turn pass image data on to software for analysis and interpretation as sound synthesis and signal processing procedures. The ...

The present study examined the impact of visualization and graphic organizers as pre-listening strategies on English as a foreign language (EFL) learners’ cognitive, behavioral, and emotional engagement and their listening comprehension. To do so, this study was carried out in three listening classes at Islamic Azad University of Mashhad. The participants included 80 junior EFL university stude...

Along with computing capability of the Graphic Processing Unit (GPU) getting more powerful, GPU is widely applied to the general purpose computing not just restrict to graph manipulation. Remote sensing image data can be parallel processed in many of the image fusion arithmetic. The fusion arithmetic in spatial domain is mapped to the SIMD computing way on GPU. This paper realized the product f...

Pedagogy Transparency is a quality driven concept built from the junction of the new pedagogy movement, based on Vygotsky ́s social interactionist theory, and the notion of information disclosure. Pedagogy Transparency aims the disclosure to students of how they are being taught and why, as to improve their awareness about the learning process. We present a study conducted to evaluate three peda...

It is customary for the outgoing President of AIS to publish a report in CAIS on the activities during his or her tenure and on future directions for the organization. This is such a report. On becoming President I was fortunate in finding an organization in good shape thanks to the excellent work of my predecessors. Consequently, AIS faced no immediate crises and it was possible to focus on so...

Click is a new software architecture for building flexible and configurable routers. A Click router is assembled from packet processing modules called elements. Individual elements implement simple router functions like packet classification, queueing, scheduling, and interfacing with network devices. Complete configurations are built by connecting elements into a graph; packets flow along the ...
