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...

A sequence S is potentially Km−C4 graphical if it has a realization containing a Km−C4 as a subgraph. Let σ(Km−C4, n) denote the smallest degree sum such that every n-term graphical sequence S with σ(S) ≥ σ(Km−C4, n) is potentially Km−C4 graphical. In this paper, we prove that σ(Km−C4, n) ≥ (2m−6)n−(m−3)(m−2)+2, for n ≥ m ≥ 4. We conjectured that equality holds for n ≥ m ≥ 4. We proved that thi...

A sequence S is potentially Kp,1,1 graphical if it has a realization containing a Kp,1,1 as a subgraph, where Kp,1,1 is a complete 3partite graph with partition sizes p, 1, 1. Let σ(Kp,1,1, n) denote the smallest degree sum such that every n-term graphical sequence S with σ(S) ≥ σ(Kp,1,1, n) is potentially Kp,1,1 graphical. In this paper, we prove that σ(Kp,1,1, n) ≥ 2[((p + 1)(n − 1) + 2)/2] f...

a title sequence is the beginning and the audience’s first center of attention to the film, in which the film’s title, key production and cast and crew along with some special notions related to the film’s content are introduced through typography. a film title sequence may include live action, animation, music, still images and graphics. with the invention of the cinematograph, in order to ide...

The methods for identification of near-duplicates in electronic scientific papers, which include the content same type, example, text data, mathematical formulas, numerical etc. were described. For method locally sensitive hashing with finding Hamming distance between elements indices papers was formalized. If exceeds a fixed threshold, paper contains near-duplicate. sub-sequences each work are...

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...
