this paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. in this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. the robust controller is designed on the basis of fractional lyapunov stability theory. furthermore, the effects of model uncertainti...

the soil bioengineering is an applied science that it is the composition of structural, biological and environment concepts for soil erosion, sediment and flood control. biotechnical engineering techniques rely on biological knowledge to build geotechnical and hydraulic structures and to secure unstable slopes and banks. the largest enhancement in development of new soil bioengineering methods ...

Invaginations are partial enclosures formed by surfaces. Typically biological membranes; they abound in nature. In this paper, we consider fundamentally different structures: elastically stabilized invaginations. Focusing on spherical invaginations elastic membranes, carried out experiments and mathematical modeling to understand the stress strain fields underlying stable structures. Friction p...

We suggested earlier a new sustainable method for permafrost thermal stabilization that combines passive screening of solar radiation and precipitation with active solar-powered cooling the near-surface soil layer thus preventing heat penetration in depth. Feasibility this has been shown by calculations, but needed experimental proof. In article, we are presenting results temperature measuremen...

It is well known that biological pattern formation the Turing mechanism, in which a homogeneous steady state destabilized by addition of diffusion, though it stable kinetic ODEs. However, states are unstable ODEs rarely mentioned. This paper concerns reaction diffusion advection system under Neumann boundary conditions, where Our results provide stabilization strategy for same state, combinatio...

there are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of china lands which are facing serious problem of desertification. theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofnortheast china, north central china and most of northwest china. biological methods are theultimate way for drift sand stabilization and a fu...

BioModel Analyzer (bma) is a tool for modeling and analyzing biological networks. Designed with a lightweight graphical user interface, the tool facilitates usage for biologists with no previous knowledge in programming or formal methods. The current implementation analyzes systems to establish stabilization. The results of the analysis— whether they be proofs or counterexamples—are represented...

Carbon nanotubes (CNTs) are increasingly studied for innovative biotechnological applications particularly where they are combined with essential biological materials like lipids. Lipids have been used earlier for enhancing the dispersibility of CNTs in aqueous solutions. Here we report a novel application of CNTs for stabilization of internally self-assembled nanostructured lipid particles of ...

In this paper, we address the problem of the restoration of image sequences which have been affected by local intensity modifications (local contrast changes). Such artifacts can be encountered in particular in biological or archive film sequences, and are usually due to inconsistent exposures or sparse time sampling. In order to reduce such local artifacts, we introduce a local stabilization o...
