Sub-gap conductance at a large area junction with a rough interface of a ferromagnet and a high-T C superconductor is superimposed by multiple peaks which is not expected from an ideal point contact Andreev reflection process. We demonstrate this phenomenon by measuring resistance as a function of bias voltage of a Co/Y 1 Ba 2 Cu 3 O 7−δ junction with contact area 50 x 70 µ m 2 at various tempe...

The purpose of this paper is towards the algebraic study of rough finite state machines, i.e., to introduce the concept of homomorphisms between two rough finite state machines, to associate a rough transformation semigroup with a rough finite state machine and to introduce the concept of coverings of rough finite state machines as well as rough transformation semigroups.

In this article we consider rough differential equations (RDEs) driven by non-geometric rough paths, using the concept of branched rough paths introduced in [Gub10]. We first show that branched rough paths can equivalently be defined as γ-Hölder continuous paths in some Lie group, akin to geometric rough paths. We then show that every branched rough path can be encoded in a geometric rough path...

Performance of electrostatic process, the properties of the fibers and stability of the layer is primarily determined by several limiting conditions such as parameters of process itself, properties of polymer solution, and ambient conditions. Anyway, the conditions of the process are set as ideal the final nanofibers cloth contains defects. Rough defects are seen as droplets of polymer, thinned...

Digital orthoimage compose an efficient and economic way for the representation of two-dimensional texture information. This kind of information is functional when the user has to evaluate, analyze or measure the objects presented in the image. If the projection has to be performed on a single plane and the form of the object is not rough, the process is simple and well-known as simple rectific...

location selection is one of the most important activities in establishment of bank branches. choosing a suitable location have a direct impact on the performance of banks and also facilitating the achievement of other objectives. there are a lot of influential factors on the location selection which are complicated and therefore the traditional methods cannot be used. so we need to have a suit...

we consider the fundamental relation  on a semihypergroup  to interpret the lower and upper approximations as subsets of the fundamental semigroup  and we give some results in this connection. also, we introduce the notion of a bi-hyperideal to study the relationship between approximations and bi-hyperideals.
