Let $G$ be a connected graph with minimum degree $delta$ and edge-connectivity $lambda$. A graph ismaximally edge-connected if $lambda=delta$, and it is super-edge-connected if every minimum edge-cut istrivial; that is, if every minimum edge-cut consists of edges incident with a vertex of minimum degree.In this paper, we show that a connected graph or a connected triangle-free graph is maximall...
Artifact awareness is one person’s up to the moment knowledge of the artifacts that other group members are working with. Such awareness contributes to the overall information necessary for fluid group coordination and interaction. Yet current systems treat artifact awareness quite differently from the interpersonal awareness of group members using the artifact. Our approach differs. We exploit...
let $g$ be a simple graph of order $n$ and size $m$.the edge covering of $g$ is a set of edges such that every vertex of $g$ is incident to at least one edge of the set. the edge cover polynomial of $g$ is the polynomial$e(g,x)=sum_{i=rho(g)}^{m} e(g,i) x^{i}$,where $e(g,i)$ is the number of edge coverings of $g$ of size $i$, and$rho(g)$ is the edge covering number of $g$. in this paper we stud...
let g=(v,e) be a simple graph. an edge labeling f:e to {0,1} induces a vertex labeling f^+:v to z_2 defined by $f^+(v)equiv sumlimits_{uvin e} f(uv)pmod{2}$ for each $v in v$, where z_2={0,1} is the additive group of order 2. for $iin{0,1}$, let e_f(i)=|f^{-1}(i)| and v_f(i)=|(f^+)^{-1}(i)|. a labeling f is called edge-friendly if $|e_f(1)-e_f(0)|le 1$. i_f(g)=v_f(1)-v_f(0) is called the edge-f...
PURPOSE To evaluate recessed elliptical centric ordering of k-space in renal magnetic resonance (MR) angiography. METHODS All imaging was performed on the same 1.5 T MR imaging system (GE Signa CVi) using the body coil for signal transmission and a phased array coil for reception. Gd, 30 ml, was injected manually at 2 ml/sec timed with automatic triggering (SmartPrep). In thirty patients usin...
Vastly inconsistent definitions of the term “the IT artifact” in leading journals and conferences demonstrate why it no longer means anything in particular and should be retired from the active IS lexicon. Examples from the literature show why artifact-cousins, such as the IS artifact, sociotechnical artifact, social artifact, and ensemble artifact should be used with great care, if not retired...
