A Dynamic Model of Crowdfunding [PDF]
SSRN Electronic Journal, 2016 Crowdfunding is quickly emerging as an alternative to traditional methods of funding new products. In a crowdfunding campaign, a seller solicits financial contributions from a crowd, usually in the form of pre-buying an unrealized product, and commits to producing the product if the total amount pledged is above a certain threshold.

Observation-based correction of dynamical models using thermostats [PDF]
, 2017 Models used in simulation may give accurate short-term trajectories but distort long-term (statistical) properties. In this work, we augment a given approximate model with a control law (a ‘thermostat’) that gently perturbs the dynamical system to target

Dynamical behavior of alternate base expansions [PDF]
, 2023 We generalize the greedy and lazy -transformations for a real base to the setting of alternate bases, which were recently introduced by the first and second authors as a particular case of Cantor bases. As in the real base case, these new transformations,

Journal for Person-Oriented Research, 2018 One challenge to understanding mechanisms of behavior change (MOBC) completely among individuals with alcohol use disorder is that processes of change are theorized to be complex, dynamic (time varying), and at times non-linear, and they interact with ...

Magnetic Resonance in Medicine, 2000 Most statistical methods for assessing activated voxels in fMRI experiments are based on correlation or regression analysis. In this context the main assumptions are that the baseline can be described by a few known basis-functions or variables and that the effect of the stimulus, i.e. the activation, stays constant over time. As these assumptions are

Standalone DC microgrids as complementarity dynamical systems: Modeling and applications [PDF]
, 2015 It is well known that, due to bimodal operation as well as existent discontinuous differential states of batteries, standalone microgrids belong to the class of hybrid dynamical systems of non-Filippov type.

Dynamic model abstraction [PDF]
Proceedings of the 28th conference on Winter simulation - WSC '96, 1996 While complex behavior can be generated through simple systems, as in chaotic and nonlinear systems, complex systems axe found where a systems study contains multiple physical objects and interactions. Through the use of hierarchy, we are able to simplify and organize the complex system.

Generalized Structural Kinetic Modeling: A Survey and Guide
Frontiers in Molecular Biosciences, 2022 Many current challenges involve understanding the complex dynamical interplay between the constituents of systems. Typically, the number of such constituents is high, but only limited data sources on them are available.

Time-Dependent Dynamical Systems and Geophysical Flows [PDF]
, 2003 This thesis presents a dynamical systems approach to transport and mixing in geophysical flows. First, new algorithms are developed that allow one to study a dynamical system that is described in a variety of ways such as by means of observational data ...

DCMIP2016: a review of non-hydrostatic dynamical core design and intercomparison of participating models [PDF]
Geoscientific Model Development, 2017 Atmospheric dynamical cores are a fundamental component of global atmospheric modeling systems and are responsible for capturing the dynamical behavior of the Earth's atmosphere via numerical integration of the Navier–Stokes equations.
