The effect of tillage, crop establishment and weed management was studied on theperformance of wheat grown after soybean at New Delhi, India during 2010-11 to 2011-12.Sixteen treatment combinations involved 2 tillage, viz. conventional tillage (CT) and zero tillage(ZT), two crop establishment practices, viz. raised-bed and flat-bed and four weed management,viz. isoproturon + hand weeding, mesos...

An equivalence graph is a vertex disjoint union of complete graphs. For a graph G, let eq(G) be the irdnimum number of equivalence subgraphs of G needed to cover all edges of G. Similarly, let cc(G) be the minimum number of complete subgraphs of G needed to cover all its edges. Let H be a graph on n vertices with ma,'dmal degree _~d (and minimal degree --~ 1), and let G=I~ be its complement. We...

Composable safety certification envisions reuse of safety case argument-fragments together with safety-relevant components in order to reduce the cost and time needed to achieve certification. The argumentfragments could cover safety aspects relevant for different contexts in which the component can be used. Creating argument-fragments for the out-of-context components is time-consuming and cur...

In this paper a schema of graphical parameters is proposed. Based on the parameter integrity introduced by Barefoot, Entringer and Swart, members Ψ(G) of this schema have the general form Ψ(G) = min{ |S| + ψ(G − S) : S ⊂ V (G) }, where ψ(G) is another given graphical parameter. Examples include integrity, mean integrity, connectivity and vertex cover number. General results and bounds for the s...

We show that there exists a Martin-Löf random degree which has a strong minimal cover.

We prove the non-uniform hyperbolicity of the Kontsevich-Zorich cocycle for a measure supported on abelian differentials which come from nonorientable quadratic differentials through a standard orienting, double cover construction. The proof uses Forni’s criterion [For11] for non-uniform hyperbolicity of the cocycle for SL(2,R)-invariant measures. We apply these results to the study of deviatio...
