The concepts of ‘lesson drawing’ and ‘policy transfer’ have become increasingly influential ways of understanding public policy, especially in the UK. However, the main proponents of the concepts, Rose for ‘lesson drawing’ and Dolowitz and Marsh for ‘policy transfer’, have difficulty in providing convincing answers to three questions that are important for them and those engaged in similar stud...

Among various styles of tree drawing reported in the literature, balloon drawing enjoys a desirable feature of displaying tree structures in a rather balanced fashion. Each subtree in the balloon drawing of a tree is enclosed in a circle. Along any path from the root node, the radius of each circle reflects the number of descendants associated with the root node of the subtree. In this paper, w...

Let G = (V,E) be a graph. All graphs considered are simple, £nite and undirected. A grid drawing of G is an injective mapping θ : V → Z such that for all edges vw ∈ E and vertices x ∈ V , θ(x) ∈ θ(v)θ(w) implies that x = v or x = w, where ab denotes the line-segment with endpoints a and b. That is, a grid drawing of a graph represents each vertex by a distinct gridpoint in the plane, and each e...

This paper gives an overview of a deep drawing process by pressurized liquid medium separated from the sheet by a rubber diaphragm. Hydroforming deep drawing processing of sheet metal parts provides a number of advantages over conventional techniques. It generally increases the depth to diameter ratio possible in cup drawing and minimizes the thickness variation of the drawn cup. To explore the...

This study investigated the deep drawing of square cups using high-strength du-al phase DP600 and DP800 sheets via both experimental finite element meth-ods. The limiting ratio (LDR) wall thickness distribution were exam-ined. initial materials used in was equal to 1-mm. experiments carried out at room temperature Teflon film graphite spray lubricants same time. In terms LDR, numerical results ...
