Критика антикоммунистических взглядов на соотношение классового и общечеловеческого в воспитании

This work introduces a mathematical model for laser cutting which involves two coupled nonlinear partial differential equations. The model will be investigated by linear stability analysis to study the occurence of ripple formations at a cutting surface. We define a measurement for the roughness of the cutting surface and give a method for minimizing the roughness with respect to process parameters. A numerical solution of this nonlinear optimization problem will be presented and compared with the results of the linear stability analysis

Web-Wide Application Customization:The Case of Mashups

Application development of is commonly a balancing of interests, as the question of what should actually be implemented is answered differently by different stakeholders. This paper considers mashups, which are a way of allowing an application to grow beyond the capabilities of the original developers. First, it introduces several approaches to integrate mashups into the services, or Web pages, that they are based upon. These approaches commonly implement ways to determine which mashups are potentially relevant for display in a certain Web page context. One approach, ActiveTags, enables users to create reliable mashups based on tags, which effectively, leads to customized views of Web pages with tagged content. A scenario that demonstrates the potential benefits of this approach is presented. Second, a formalization of the approaches is presented which uses a relational analog to show their commonalities. The abstraction from implementation specifics opens the range of vision for fundamental capabilities and gives a clear picture of future work

Web Service Discovery – Reality Check 2.0

In practice the ability to find the right Web service decides between a functionality being implemented anew and at least the possibility of executing it via a service. This report evaluates existing public portals for Web service discovery with respect to their characteristics and their acceptance by developers. For this, we distinguish different possible settings and use cases and evaluate how these are supported in practice. Only few of the publicly available Web service registries are growing in size and importance, with the use case best supported being the pre-programming phase of evaluation of the service landscape. <br

Topologically non-trivial quantum layers

Given a complete non-compact surface embedded in R^3, we consider the Dirichlet Laplacian in a layer of constant width about the surface. Using an intrinsic approach to the layer geometry, we generalise the spectral results of an original paper by Duclos et al. to the situation when the surface does not possess poles. This enables us to consider topologically more complicated layers and state new spectral results. In particular, we are interested in layers built over surfaces with handles or several cylindrically symmetric ends. We also discuss more general regions obtained by compact deformations of certain layers.Comment: 15 pages, 6 figure
