In a dynamical systems model, movement patterns are dictated by several variables, called control parameters. The goal of this pilot study was to assess whether changes on a static balance task can be described by a dynamical systems model with body inertial properties as one of the potential control parameters. Three aspects of a dynamic system were examined in relation to a 2-ft. static balance task: a relation between the changes in the balance pattern and the control parameter, a relation between the stability of the balance pattern and the stability under perturbed conditions (1-ft. balance task), and during the perturbation lack of relation between the balance pattern and the control parameters. Nine adolescent boys, 15.3 ± 1.0 yr. old were examined twice over a 14-wk. period. During each testing session, participants' body mass, moments of inertia, and radius from the ankle to the center of mass were calculated, after which 1- and 2-ft. balance tasks were performed. Center of pressure coordinates were recorded using a Kistler force plate. The body parameters were used to calculate the natural frequency of the body to represent the control parameter. Significant relations among all three aspects of a dynamic system examined in both the lateral and anterior-posterior axes were found. This investigation was designed for exploratory purposes and limited to correlational analysis; therefore, no concrete conclusions could be drawn. The results, however, suggest a dynamical systems approach to the study of static balance patterns may be possible.

Base on the constitutive model expressed by convolution method for viscoelastic materials with damage, the initial-boundary-value problem analyzing static-dynamic behaviors of homogeneous, isotropic viscoelastic. Tiimoshenko beams with damage, placed on a viscoelastic foundation, is formulated under the case of finite deflections. And we adopt the model to simulate the dynamical behaviors of viscoelastic piles with damage placed on a viscoelastic foundation. The numerical methods in nonlinear dynamics are used to solve the simplified systems. The phase-trajectory diagrams, Poincare sections and bifurcation diagrams are all obtained. The influences of the material parameters of pile and foundation and load parameter on the dynamic behavior of the nonlinear system are investigated in detail.

Long-range synchrony from short-range interactions is a familiar pattern in biological and physical systems, many of which share a common set of ‘universal’ properties at the point of synchronization. Common biological systems of coupled oscillators have been shown to be members of the Ising universality class, meaning that the very simple Ising model replicates certain spatial statistics of these systems at stationarity. This observation is useful because it reveals which aspects of spatial pattern arise independently of the details governing local dynamics, resulting in both deeper understanding of and a simpler baseline model for biological synchrony. However, in many situations a system’s dynamics are of greater interest than their static spatial properties. Here, we ask whether a dynamical Ising model can replicate universal and non-universal features of ecological systems, using noisy coupled metapopulation models with two-cycle dynamics as a case study. The standard Ising model makes unrealistic dynamical predictions, but the Ising model with memory corrects this by using an additional parameter to reflect the tendency for local dynamics to maintain their phase of oscillation. By fitting the two parameters of the Ising model with memory to simulated ecological dynamics, we assess the correspondence between the Ising and ecological models in several of their features (location of the critical boundary in parameter space between synchronous and asynchronous dynamics, probability of local phase changes and ability to predict future dynamics). We find that the Ising model with memory is reasonably good at representing these properties of ecological metapopulations. The correspondence between these models creates the potential for the simple and well-known Ising class of models to become a valuable tool for understanding complex biological systems.

AbstractIn this article, we investigated a generalised scalar field cosmology characterised by a time-dependent coupling function, a time-dependent cosmological constant, a chameleonic field, and a time-dependent equation of state parameter. Based on a particular choice of the Hubble parameter as function of the scalar field and its time derivative, we have investigated the dynamics of the Friedmann–Robertson–Walker flat universe. We have observed that for a particular choice of the free parameters in the theory, the universe accelerates with time and asymptotically tends toward a static universe. For specific values of the free parameters, the asymptotically static universe may be dominated by phantom energy or a cosmological constant without the need to implement in the theory multiple scalar fields or additional interactions. It is also pointed out that an asymptotically static universe is as well one special class of solutions for Horndeski and generalised galileons cosmologies. Special properties and features are discussed accordingly.

The properties and observational manifestations of the dynamical dark energy on the cosmological and astrophysical scales are discussed. We consider the dynamical dark energy in the form of quintessential and phantom scalar fields with different parameters of the equation of state and the effective sound speed. The evolution of the dynamical dark energy and its impact on the dynamics of expansion of the Universe, halos, and voids, and its behavior in the static gravitational fields of astrophysical objects are analyzed. The current state and possible tests designed to establish the nature of dark energy are highlighted.

We report the results of the characterization of local Monte Carlo (MC) dynamics of an equilibrium bond fluctuation model polymer matrix (BFM), in time interval typical for MC simulations of non-linear optical phenomena in host-guest systems. The study contributes to the physical picture of the dynamical aspects of quasi-binary mosaic states characterized previously in the static regime. The polymer dynamics was studied at three temperatures (below, above and close to the glass transition), using time-dependent generalization of the static parameters which characterize local free volume and local mobility of the matrix. Those parameters play the central role in the kinetic MC model of host-guest systems. The analysis was done in terms of the probability distributions of instantaneous and time-averaged local parameters. The main result is the characterization of time scales characteristic of various local structural processes. Slowing down effects close to the glass transition are clearly marked. The approach yields an elegant geometric criterion for the glass transition temperature. A simplified quantitative physical picture of the dynamics of guest molecules dispersed in BFM matrix at low temperatures offers a starting point for stochastic modeling of host-guest systems.

Atomic displacement parameters (a.d.p.'s), together with vibrational spectra (Raman and IR) and thermodynamic functions, have been calculated for some minerals of the garnet group, such as pyrope (Mg3Al2Si3O12), grossular (Ca3Al2Si3O12), andradite (Ca3Fe2Si3O12) and almandine (Fe3A12Si3O12). For this purpose, a rigid-ion Born–von Karman model has been applied, using empirical atomic charges and valence force fields derived from a best fit to the vibrational spectra of a group of orthosilicates and oxides. Agreement with the experimental data is good, with the only exception of pyrope and almandine: for these minerals the calculated a.d.p.'s of the Mg2+ atom in the former and of the corresponding Fe2+ atom in the latter are too low. This result confirms the unusual behaviour of these atoms, for which dynamic disorder has been claimed. However, if the values of the specific heat and entropy are considered and compared with our calculations, this situation can be best explained assuming the transition to static disorder of the Mg2+ and Fe2+ atoms to occur at low temperature.

The local activity theory [Chua, 97] offers a constructive analytical tool for predicting whether a nonlinear system composed of coupled cells, such as reaction-diffusion and lattice dynamical systems, can exhibit complexity. The fundamental result of the local activity theory asserts that a system cannot exhibit emergence and complexity unless its cells are locally active. This paper gives the first in-depth application of this new theory to a specific Cellular Nonlinear Network (CNN) with cells described by the FitzHugh–Nagumo Equation. Explicit inequalities which define uniquely the local activity parameter domain for the FitzHugh–Nagumo Equation are presented. It is shown that when the cell parameters are chosen within a subset of the local activity parameter domain, where at least one of the equilibrium state of the decoupled cells is stable, the probability of the emergence of complex nonhomogenous static as well as dynamic patterns is greatly enhanced regardless of the coupling parameters. This precisely-defined parameter domain is called the "edge of chaos", a terminology previously used loosely in the literature to define a related but much more ambiguous concept. Numerical simulations of the CNN dynamics corresponding to a large variety of cell parameters chosen on, or nearby, the "edge of chaos" confirmed the existence of a wide spectrum of complex behaviors, many of them with computational potentials in image processing and other applications. Several examples are presented to demonstrate the potential of the local activity theory as a novel tool in nonlinear dynamics not only from the perspective of understanding the genesis and emergence of complexity, but also as an efficient tool for choosing cell parameters in such a way that the resulting CNN is endowed with a brain-like information processing capability.

Magnetické materiály a z nich vyrobené nanostruktury jsou v průběhu posledních let studovány pro jejich aplikace v např. záznamových médiích a logických obvodech. Tato práce navazuje na náš předchozí výzkum tohoto oboru s hlavním zaměřením na statické a dynamické vlastnosti nanostrukturovaných magnetických materiálů, jako například NiFe, CoFeB a YIG. Práce začíná teoretickým úvodem s popisem mikromagnetických systémů, dynamiky magnetických vortexů, feromagnetické rezonance (FMR) a spinových vln včetně jejich disperzních vlastností. Následuje popis použitých experimentálních metod a první experimentální část zabývající se nukleačním procesem magnetického vortexu, jinými slovy procesem transformace ze saturovaného stavu do spinové konfigurace magnetického vortexu v průběhu snižování magnetického pole. Jsou použity mikroskopické metody zobrazující magnetickou strukturu materiálu, jmenovitě Lorentzova transmisní elektronová mikroskopie a rentgenová transmisní mikroskopie. Výsledky jsou poté korelovány s měřením elektrické odezvy pomocí jevu anizotropní magnetorezistence. Výhodou elektrických měření je, že plně elektrická detekce dovoluje použití tohoto systému v uzavřených systémech integrovaných obvodů. Výsledky oblasti nukleací magnetických vortexů ukazují, že při tomto procesu prochází magnetizace v nano- a mikrometrových magnetických discích několika fázemi s růsnými typy spinových konfigurací nazvaných nukleační stavy. Dále je představeno měření magnetických materiálů pomocí vektorového síťového analyzátoru (VNA), což je aplikováno na měření resonance magnetických vortexů (určení gyrotropické frekvence a měření vysokofrekvenčních módů), feromagnetické rezonance tenkých vrstev (získání základních magnetických materiálových parametrů) a spektroskopii spinových vln. Právě spektroskopie spinových vlna je rozvinuta za účelem měření disperzních relací tenkých magnetických vrstev, což je základní charakteristika, jejíž znalost je důležitá v návrhu aplikací. Nakonec je představeno anténní zařízení, díky kterému lze oddělit magnetické buzení od vzorku samotného bez nutnosti absolvovat proces elektronové litorafie, což je zapotřebí v klasickém přístupu antény na vzorku a kontaktování vysokofrekvenční sondou. Toto zařízení se skládá ze skleněného kantilívru, na kterém je vyrobena budící anténa, konektoru a spojovacího prvku v podobě plošného spoje. Celé zařízení je díky umístění na x-y-z stolek s náklonem pozicovatelné a lze tedy měřit v jakémkoliv místě vzorku. Umístění antény na sklo umožňuje navigaci pomocí mikroskopu a optické měření, např. metodou Brillouinova světelného rozptylu (BLS) nebo Kerrova jevu.

The goal of this master thesis is to develop an algorithm for solving cables on pulleys, which would be more efficient and accurate than existing algorithm used in software RFEM. This algorithm was integrated to the program for static and dynamic analysis of structures, in the form of particular program module. This work also contains examples of using this algorithm. The comparison of expected results with outcomes from the program is presented. The suitability for common practise is examined based on this comparison. The examples showed that the new algorithm for solving of cables on pulleys is more powerful and more accurate than existing solutions and most likely does not has equivalent competition.

This project seeks to demonstrate routing optimization that would allow pedestrian and micromobility user groups to select and prioritize different route features according to their preferences. Through the creation of a routing demonstrator that considers both static and dynamic parameters in the form of pavement quality, elevation climb, travel time, and air quality, along with user-specified weights for their prioritization of each of these parameters, a number of routes were created and mapped to qualitatively compare against routes representing only a shortest path.

In the previous chapters we described the basic principles of density functional theory, gave examples of how accurate it is to describe static magnetic properties in general, and derived from this basis the master equation for atomistic spin-dynamics; the SLL (or SLLG) equation. However, one term was not described in these chapters, namely the damping parameter. This parameter is a crucial one in the SLL (or SLLG) equation, since it allows for energy and angular momentum to dissipate from the simulation cell. The damping parameter can be evaluated from density functional theory, and the Kohn-Sham equation, and it is possible to determine its value experimentally. This chapter covers in detail the theoretical aspects of how to calculate theoretically the damping parameter. Chapter 8 is focused, among other things, on the experimental detection of the damping, using ferromagnetic resonance.

Pulmonary function tests in critical illness 90End-tidal CO2 monitoring 92Pulse oximetry 94Pulmonary function test results in critically ill patients can be important prognostically and guide ventilatory and weaning strategies. However, they are not straightforward to measure in mechanically ventilated patients and remain limited to dynamic volumes. Fortunately, most modern mechanical ventilators are able to calculate and display static and dynamic lung volumes, together with derived values for airway resistance, compliance and flow/volume/time curves. The ability to monitor these changes after altering ventilatory parameters has enabled more sophisticated adjustments of ventilation, to prevent potentially damaging mechanical ventilation....

AbstractOne of the principal methods of preventing large earthquakes is stimulation of a large series of small events. The result is a transfer of the rapid tectonic dynamics in a creep mode. In this chapter, we discuss possibilities for such a transfer in the framework of simplified models of a subduction zone. The proposed model describes well the basic characteristic features of geo-medium behavior, in particular, statistics of earthquakes (Gutenberg Richter and Omori laws). Its analysis shows that local relatively low-energy impacts can switch block dynamics from stick–slip to creep mode. Thus, it is possible to change the statistics of seismic energy release by means of a series of local, periodic, and relatively low energy impacts. This means a principal possibility of “suppressing” strong earthquakes. Additionally, a modified version of the Burridge-Knopoff model including a simple model for state dependent friction force is derived and studied. The friction model describes a velocity weakening of friction between moving blocks and an increase of static friction during stick periods. It provides a simplified but qualitatively correct stability diagram for the transition from smooth sliding to a stick–slip behavior as observed in various tribological systems. Attractor properties of the model dynamic equations were studied under a broad range of parameters for one- and two-dimensional systems.

Viscoelastic components are incorporated into automobile and aerospace structures system in order to damp mechanical vibrations. Viscoelastic components are a key element in designing desired dynamic behaviour of mechanical systems. Viscoelastic components dynamic characteristics are often very complex, due to the dependence of its response on several variables, such as frequency, amplitude, preload, and temperature. These dependencies can be critical in capturing the mechanical proprieties and so non linear dynamical behaviour may appear. Assuming that non linearities are due to non linear elasticity, the non linear Generalized Maxwell Model (GMM) is proposed to characterize dynamics of viscoelastic components. Parameters of GMM are identified from Dynamic Mechanical Analysis (DMA) tests for different excitation frequencies. A particular result from identification is that the non linear stiffness is dependent upon displacement amplitude and static displacement under static preload. The significance of this result is that the non linear dynamics of the viscoelastic component can be represented by a simple analytical model capable to produce accurate results. Comparison between measurements and simulations of dynamic stiffness of viscoelastic component has been carried on.

This paper deals with μ-synthesis control approaches for a class of uncertain dynamic systems with unknown comple multi-loop hysteresis nonlinearity. By decoupling the hysteresis from the system dynamics, an uncertain linear dynamic system subjected to a static hysteretic input is achieved. A bound of uncertainty for the parameters of the dynamic system is considered and the hysteresis is reduced to a line with a known slope plus a varying function representing the difference of the approximate line and the hysteresis response. For the described uncertain system, μ-synthesis method is used to achieve both stabilization and tracking performance within a desired precision and bandwidth. Simulation performed on a perturbed nonlinear plant demonstrate the effectiveness of the approach when compared to other methods.
