We developed a nanofiber scaffold by blending PLLA with collagen I, suitable for bone regeneration. Among several PLLA-COLI ratios tested, cell growth was better enhanced when blends with a ratio of PLLA-COLI 4:1 were used. Here, growth as well as osteoblast differentiation of hMSC was improved when compared to PLLA nanofibers alone. Therefore, blending is a suitable tool to enhance PLLA nanofi...

In this paper, we show an extension of the model proposed by Sabourdy, combining various implicit surfaces with soft blending capacities in a CSG tree. This extension allows integration of plane surfaces, skeletons and many other types of implicit surfaces. It particularly develops the blending possibilities offered by this approach. The model is then able to generate a wide variety of shapes o...

A mathematical framework for the coupling of atomistic and continuum models by blending them over a subdomain subject to a constraint is developed. Using the framework, four classes of atomistic-to-continuum (AtC) blending methods are established, their consistency is studied, and their relative merits discussed. In addition, the framework helps clarify the origin of ghost forces and formalizes...

This paper studies the induced L2-norm problem for switched linear parameter varying (LPV) systems using a blending method. For a switched LPV system where the parameters are grouped into slow-varying and fast-varying parameters, the blending method is used to construct blended Lyapunov functions based on the multiple Lyapunov functions conditions in terms of linear matrix inequalities (LMIs). ...

application of supramolecular polymer blending in preparation of materialswith adjustable mechanical properties is addressed. it is anticipated that the microstructure and properties of polymer blends are drastically controlled by the inter-molecular interactions. on this basis, the effect of strongly dimerising ureidopyrimidinone end groups (upy) with the capability of quadruple hydrogen bondi...

The paper presents a technique for construction of C interpolating rational Bézier spline curves by means of blending rational quadric Bézier curves. A class of polynomials which satisfy special boundary conditions is used for blending. Properties of the polynomials are considered. The constructed spline curves have local shape control that make them useful in such geometric applications as rea...

The implicit surface modelling technique can be used to model “soft” objects, objects whose surface or topology changes over time. It offers the opportunity of modelling and animating relatively complex shapes using only a few primitives. The final object is constructed by blending the primitives, and as the primitives are moved the blended surface changes shape. This can cause problems with ob...

This paper reviews the development of fuzzy systems and the problem of time delay control in nonlinear systems. Based on this review, a fuzzy Lyapunov method defined in fuzzy blending quadratic Lyapunov functions is proposed from which to derive stability conditions. In the controller procedure, a parallel distributed compensation (PDC) scheme is utilized to construct a global fuzzy logic contr...
