Curved tubes of non-circular cross section are widely used in various fields technology. The change the planned operating modes technological processes is associated with wear executing mechanisms, which caused by unstable frequencies and amplitudes oscillations. Thus, issue determining oscillation parameters these elements becomes more significant. technique results tests for stresses, displac...

We consider the following standard problems appearing in optimal mass transportation theory: • when a transference plan is extremal, • when a transference plan is the unique transference plan concentrated on a set A, • when a transference plan is optimal. We study these three problems with a general approach: (1) choose some necessary conditions, depending on the problem we are considering; (2)...

This article provides a rationale for understanding and interpreting the “public use” requirement within eminent domain law. The rationale is based on two factors. First, whereas the government often needs the power of eminent domain to avoid the problem of strategic holdout, private parties are usually able to purchase property through the use of secret buying agents. The availability of secre...

This paper introduces a new approach for improving hypermedia design, by providing the author with a tool to visualise, examine, and analyse the structure of documents containing hypermedia links. Our proposal is a new representation method the purpose of which is not to show the document structure in graphical form in order to enable the users to know where they are, where they can go next, or...

We present our experience on designing interactive applications for Sphere, our multi-touch-sensitive spherical display prototype. We believe that the compelling application design for future non-flat user interfaces will greatly depend on exploiting some unique characteristics of the given form factor. While our observations primarily focus on spherical displays, we envision that the ideas pre...

In this paper we investigate the form of calibrated M5-branes in the presence of a nonvanishing 3-form field H. We discuss the influence of the H-field on the deformation of supersymmetric n-cycles (in particular SLAG submanifolds in R). In addition we argue for a construction which relates calibrated M5-branes of different “curved” dimensions to each other. ∗1 [email protected] 2miemie...

Protein molecules absorb and crystallise on He, N 2 , O CO gas bubbles as soft templates with prompted nucleation gas–liquid–solid interface. Crystals attached bubble form curved crystal surface float in the solution.

A bstract The recently established B-RNS-GSS formalism is extended for the description of heterotic superstring in curved backgrounds. We propose a generalized action and BRST charge defined small Hilbert space with standard form an

We discuss membranes in four-dimensionalN = 1 superspace. The κ-invariance of the GreenSchwarz action implies that there is a dual version of N = 1 supergravity with a three-form potential. We formulate this new supergravity in terms of a three-form superfield in curved superspace, giving the relevant constraints on the field strength. We find the corresponding membrane soliton in the new super...
