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

Dynamic Modeling of the Electric Transportation Network [PDF]
We introduce a model for the dynamic self-organization of the electric grid. The model is characterized by a conserved magnitude, energy, that can travel following the links of the network to satisfy nodes' load. The load fluctuates in time causing local

How do blogs produce posts? What local, underlying mechanisms lead to the bursty temporal behaviors observed in blog networks? Earlier work analyzed network patterns of blogs and found that blog behavior is bursty and often follows power laws in both topological and temporal characteristics. However, no intuitive and realistic model has

A New Efficient Step-Up Boost Converter with CLD Cell for Electric Vehicle and New Energy Systems
An increase in demand for renewable energy resources, energy storage technologies, and electric vehicles requires high-power level DC-DC converters. The DC-DC converter that is suitable for high-power conversion applications (i.e., resonant, full-bridge ...

Influence of Surface Reflection (Albedo) in Simulating the Sun Drying of Paddy Rice
The sun drying of agricultural products is a complicated process involving heat transfer, mass transfer, and variable weather conditions. Surface reflection (albedo), a crop’s radiative property, plays an essential role in energy balance, and ...

Dynamic modelling with events [PDF]
This paper focusses on the behavioural aspects of the IFO23 model, an extension of the semantic model IFO defined by S. Abiteboul and R. Hull. Its originality is in the formalization of complex events and their specification, which adopts semantics and syntax indentical to those of the structural part.

Dynamic model abstraction [PDF]
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.

Drought-Induced Amplification of Saint Louis encephalitis virus, Florida
We used a dynamic hydrology model to simulate water table depth (WTD) and quantify the relationship between Saint Louis encephalitis virus (SLEV) transmission and hydrologic conditions in Indian River County, Florida, from 1986 through 1991, a period ...
