Tissue engineering deals with the growth and regeneration techniques of connective tissues or organs from a combination of cells and a scaffold to produce a functional organ. The engineering techniques therefore begin with an implantation of artificial materials, providing a proper environment for cells or tissues to be grown and functionalized. The scaffolds are often formulated with biodegrad...

This work is conducted to obtain mechanical properties of microtubule. For this aim, interaction energy in alpha-beta, beta-alpha, alpha-alpha, and beta-beta dimers was calculated using the molecular dynamic simulation. Force-distance diagrams for these dimers were obtained using the relation between potential energy and force. Afterwards, instead of each tubulin, one sphere with 55 KDa weight ...

In this paper we compare two approaches to model the vague german spatial relation in der Nähe von (English: ”close to”) to enable its usage in (semantic) web searches. A user wants, for example, to find all relevant documents regarding parks or forestal landscapes close to a city. The problem is that there are no clear metric distance limits for possibly matching places because they are only r...

Compressed air energy storage (CAES) is a large-scale technology that provides long-duration energy storage. It is promising for balancing the large-scale penetration of intermittent and dispersed sources of power, such as wind and solar power, into electric grids. The existing CAES plants utilize natural gas (NG) as fuel. However, China is rich in coal but is deficient in NG; therefore, a hybr...

We describe the natural connection between model theory and generalized polygons and give some applications of one theory to the other.

While qualitative relations (e.g. RCC8 relations) can readily be derived from spatial databases, a more difficult matter is the representation of vague spatial relations such as ‘near-to’,‘next-to’, ‘between’, etc. After surveying earlier approaches, this paper proposes a method that is tractable, learnable and directly suitable for use in natural language interfaces to spatial databases. The a...
