This paper describes a new numerical scheme for the approximation of steady state solutions to systems of hyperbolic conservation laws. It generalises the fluctuation distribution framework by allowing the underlying representation of the solution to be discontinuous. This leads to edge-based fluctuations in addition to the standard cell-based fluctuations, which are then distributed to the cel...

As renewable energy penetration increases, the lack of flexibility in a multi-renewable power system can seriously affect its own economics and reliability. To address this issue, three objectives are considered study: fluctuations on tie-line, operating cost, curtailment rate energy. Presented also is an optimal day-ahead scheduling model based MREPS for distributed generations with constraint...

Owners of combined heat and power (CHP), e.g., industrial manufacturers, are motivated to provide frequency response grids due clear financial benefits. Yet, the slow speed CHP limits its capability in providing such services. Moreover, frequent adjustments would cause a faster lifetime reduction rapid pressure fluctuation gas network. To further unlock flexibility CHP, this article integrates ...

Fluctuation Theorem: a simple consequence of a time reversal symmetry; it deals with motions which are chaotic in the strong mathematical sense of being hyperbolic and transitive (ie are generated by smooth hyperbolic evolutions on a smooth compact surface (the “phase space”) and with a dense trajectory, also called Anosov systems) and “furthermore are time reversible”. In such systems any init...

The information presented in this article is intended to make the reader aware of the most current research on the topic of flexibility and to make some practical suggestions for planning effective programs for developing flexibility in athletes. Though additional research needs to be done, we have enough knowledge to plan sound programs for reducing the incidence of injury and for promoting op...

We propose phase-like characteristics in scale-free broadband processes and consider fluctuation synchrony based on the temporal signature of significant amplitude fluctuation. Using wavelet transform, successful captures of similar fluctuation pattern between such broadband processes are demonstrated. The application to the financial data leading to the 2008 financial crisis reveals the transi...

The effects of dipolar interactions and molecular flexibility on the structure and phase behavior of bent-core molecular fluids are studied using Monte Carlo computer simulations. Some calculations of flexoelectric coefficients are also reported. The rigid cores of the model molecules consist of either five or seven soft spheres arranged in a "V" shape with external bend angle gamma. With purel...

flexibility as an ability to respond to changing circumstances is one of the vital characteristics of the natural and built environment. during the contemporary era, diversity of methods relating the architectural flexibility execution are suggested. but along with contemporary conceptual approaches toward pluralism and uncertainty, it seems that the multiplicity of approaches toward flexibilit...

background methamphetamine (ma) is a highly addictive stimulant which has destructive effects. there is also evidence that methamphetamine use in some females, partly is due to their desire to lose weight. the purpose of this study was to determine the association between family flexibility, food preoccupation and body image among crystal abuser women. objectives this study tried to evaluate wh...
