in this paper, a new t-s fuzzy hyperbolic delay model for a class of nonlinear systems with time-varying delay, is presented to address the problems of stability analysis and feedback control. fuzzy controller is designed based on the parallel distributed compensation (pdc), and with a new lyapunov function, delay dependent asymptotic stability conditions of the closed-loop system are derived v...

Today, sustainable development is one of the important issues in regard to the economy of a country. This issue magnifies the necessity for increased scrutiny towards issues such as environmental considerations and product recovery in closed-loop supply chains (CLSCs). The most important motivational factors influencing research on these topics can be considered in two general groups: environme...

This paper investigates the extent of vulnerability in the U.S. commercial banking system through a pro-cyclical interaction between the market-wide risk perception and systemwide asset management behavior. Based on a Markov regime-switching model, the proposed diagnostic framework clearly illustrates its ability to provide an early warning signal of the build-up and unwinding of fragility in t...

The cognition of spatial objects differs among people and is highly influenced by the context in which a spatial object is perceived. We investigated experimentally how humans perceive geometric figures in geometric proportional analogies and discovered that subjects perceive structures within the figures which are suitable for solving the analogy. Humans do not perceive the elements within a f...

• Der Test von modellbasiert entwickelter Software bereits auf Modell-Ebene (z.B. Model-, bzw. Software-in-the-Loop). • Der Test von einzelnen Steuergeräten in einer Laborumgebung (z.B. Hardware-in-the-Loop einzelner Steuergeräte aus Sicht des OEM) • Der Test mehrerer Steuergeräte im Verbund (z.B. Hardware-in-the-Loop Prüfständen auf Integrationsebene) • Der Test von E&E-Komponenten direkt in F...

I consider a model based on a quark–meson interaction Lagrangian. The transition amplitudes are evaluated by computing diagrams in which heavy and light mesons are attached to quark loops. The light chiral symmetry relations and the heavy quark spin-flavour symmetry dictated by the heavy quark effective theory are implemented. The model allows to compute the decay form factors and therefore can...

– A model for the evolution of a finite population in a rugged fitness landscape is introduced and solved. The population is trapped in an evolutionary loop, alternating periods of stasis to periods in which it performs adaptive walks. The dependence of the average rarity of the population (a quantity related to the fitness of the most adapted individual) and of the duration of stases on popula...

A number of improvements have been added to the existing analytical model of hysteresis loop defined in parametric form. In particular, three phase shifts are included in the model, which permits to tilt the hysteresis loop smoothly by the required angle at the split point as well as to smoothly change the curvature of the loop. As a result, the error of approximation of a hysteresis loop by th...

The basic idea of the LQC applies to every spatially homogeneous cosmological model, however only the spatially flat (so called k = 0) case has been understood in detail in the literature thus far. In the closed (so called: k=1) case certain technical difficulties have been the obstacle that stopped the development. In this work the difficulties are overcome, and a new LQC model of the spatiall...
