Changes of Sliver Irregularity in
A theoretical calculation is made to simulate the effect of drafting upon the sliver irregularity in two-zone drafting of three-over-three roller system. Two types of slivers, i.e., random sliver and optional sliver are considered. The effects of sliver count, staple fiber length, fineness of fiber, draft distribution between two drafting zones, maximal moving distance and distribution type of ...
متن کاملInternal Model Control of Textile Sliver Drafting Process
The paper is focused on modelling and control of an important textile engineering process: the textile sliver drafting process. This process plays a crucial role in textile production chain because low irregularity of drafted sliver is essential for production of high quality yarn. It is shown that this process can be modelled as a nonlinear time delay system with distributed delays. This model...
متن کاملBCFT and Sliver state
We give a comment on the possible rôle of the sliver state in the generic boundary conformal field theory. We argue that for each Cardy state, there exists at least one projector in the string field theory. ∗E-mail address: [email protected] One of the long standing problem in the string theory is the description of the geometry. Generically we do not need the space-time at all to def...
متن کاملThe irregularity and total irregularity of Eulerian graphs
For a graph G, the irregularity and total irregularity of G are defined as irr(G)=∑_(uv∈E(G))〖|d_G (u)-d_G (v)|〗 and irr_t (G)=1/2 ∑_(u,v∈V(G))〖|d_G (u)-d_G (v)|〗, respectively, where d_G (u) is the degree of vertex u. In this paper, we characterize all connected Eulerian graphs with the second minimum irregularity, the second and third minimum total irregularity value, respectively.
متن کاملThe singular geometry of the sliver
We consider “sliver” states which act as projection operators in the matter star product of Witten’s cubic string field theory. These sliver states, which might be associated with Dp-branes, are not finite norm states in the matter string Hilbert space. We describe the singularities of these states, and demonstrate that the sliver states are composed of strings having singular geometric feature...
