  where y 0 denotes the tumor size (or number of cells) at time 0, and A and α are two positive constants regulating both growth rate and saturation size. Specifically, A is the initial growth rate of the process, and α stands for the deceleration rate related to the natural death of the tumor cells. The model can also be written as a system of ordinary differential equations, which allows for Cited by:   Understanding how social and environmental factors contribute to the spatio-temporal distribution of criminal activities is a fundamental question in modern criminology.

The state of a dynamical system comprises the values of all of the state variables in the model. A time time \(t\), a discrete-time dynamical system is in one state, say \(s_t\). By applying the evolution rule, it transitions to another state, say \(s_{t+1}\). Given an initial system state—in this section, an initial population—repeated.   The marginal effects at each system state (i.e., level of e‐commerce) on the energy consumptions by sector are estimated using the respective best parameter θ (see figure 5), and then averaged to provide a total marginal net effect over all data points, as well as averaged over the most recent year () to provide a current marginal net Cited by: 1.

  It can occur when a parameter passes slowly through a Hopf bifurcation point and the system's response changes from a slowly varying steady state to slowly varying oscillations. On quantitative observation it is found that the transition is realized when the parameter is considerably beyond the value predicted from a straightforward bifurcation Cited by: Search engines aim at delivering the most relevant information whatever the query is.

Cellular automata are special cases of dynamical systems corresponding to finite state machines. For more on cellular automata see CellularAutomata.m The notebook TimeSeries.m contains examples of time series.

The computed bifurcation diagram and the two-dimensional parameter scans suggest that the seasonal perturbations causing changes in the system parameters and deciding different dynamics are able.

Predicting climate tipping points 55 Climate models as dynamical systems Thinking about modelling is a good introduction to the ideas involved in predicting climate change, so we will start from this angle. Now, to an applied mathematician, the Earth’s climate is just a very large dynamical system.

Predicting climate tipping as a noisy bifurcation: a review 5 Climate models come in varying degrees of sophistication and realism, more complex ones employing up to 3£ variables [Dijkstra,].

Predictions do not rely solely on a single ‘best model’ starting from the ‘real initial conditions’. A simple example of a dynamical system would be the equations describing the motion of a pendulum.

The equations of a dynamical system are often referred to as dynamical or evolution equations describing the change in time of variables taken to adequately describe the target system (e.g., the velocity as a function of time for a pendulum).

Climate Models as Dynamical Systems Thinking about modelling is a good introduction to the ideas involved in predicting climate change, so we will start from this angle. Now, to an applied mathematician, the Earth's climate is just a very large dynamical system that evolves in time.

Vital elements of this system are the Earth itself, its oceans and. Publisher Summary. This chapter discusses two quite different aspects of the concept of stability of a given motion of a dynamical system.

The first aspect concerns the idea of stability itself, with the object of reminding that stability in dynamics is an idea that means different things to different people and that an analysis of it soon leads to the uncovering of various basic conceptual.

Compressive sensing based reconstruction of nonlinear and complex dynamical systems. A recent line of research,, exploited compressive sensing. The basic principle is that the dynamics of many natural and man-made systems are determined by smooth enough functions that can be approximated by finite series by: The rest of the article is organized as follows.

An information-theoretic framework is developed in Section 2. Section 3 reviews the linear response theory and FDT. In Section 4, a new framework for computing the FDT using the full non-Gaussian PDF is developed, which facilitates the calculation of the linear response s applications of the simple information criterion that Author: Nan Chen, Xiao Hou, Qin Li, Yingda Li.

Chaos theory is a branch of mathematics focusing on the study of chaos—states of dynamical systems whose apparently-random states of disorder and irregularities are often governed by deterministic laws that are highly sensitive to initial conditions.

Chaos theory is an interdisciplinary theory stating that, within the apparent randomness of chaotic complex systems, there are underlying. Energy homeostasis ensures the functionality of the entire organism. The human brain as a missing link in the global regulation of the complex whole body energy metabolism is subject to recent investigation.

The goal of this study is to gain insight into the influence of neuronal brain activity on cerebral and peripheral energy metabolism.

In particular, the tight link between brain energy Cited by:   The dynamical system is said to be state observable at time t f if every initial state x(0) can be uniquely determined from the knowledge of a finite time series of the measured variable s(τ), 0 Cited by: Chaos Theory Chaos theory is a scientific principle describing the unpredictability of systems.

Heavily explored and recognized during the mid-to-late s, its premise is that systems sometimes reside in chaos, generating energy but without any predictability or direction. When the parameter η system becomes unstable as the saddle-node bifurcation occurs at η = 0 annihilating the fixed points y = ± − η ⁠.

Thus, the non-stationary influence on the saddle-node bifurcation can be assessed by examining the system stability with respect to a time-dependent bifurcation Cited by: 5. dynamical wholes clearly—and in a distributed manner—exert active power on their parts such that the overall system is maintained and enhanced.

Understanding dynamical systems can therefore revive Aristotle’s concepts of formal and final cause by offering a scientifically respectable model of how such causes operate.

Since the active power. 11 scenario. We do not investigate the influence of changes in parameter values other than a 12 ‘climate change induced’ increase in mortality rate. 13 We use models that are sufficiently complex to defy the usual analytical dynamical 14 systems analysis, but are sufficiently simple to succinctly demonstrate the efficacy of our 15 approach.

This chapter provides scientific background on biomarkers that could be useful in monitoring metabolic status in the field. It includes a discussion of the most promising biomarkers for the prediction of: (a) excessive rates of bone and muscle turnover, (b) renal function.

A fishery is an area with an associated fish or aquatic population which is harvested for its commercial or recreational value. Fisheries can be wild or farmed. Population dynamics describes the ways in which a given population grows and shrinks over time, as controlled by birth, death, and migration.

It is the basis for understanding changing fishery patterns and issues such as habitat.
