Stochastic order inequalities for systems with standby units and parallel-series configurations

Journal of Inequalities and Applications
Abstract In this paper, we first consider stochastic orderings of lifetimes of series and parallel systems with cold standby units. The strategy is to find out whether the reliability of a series or parallel system improves when standby units are installed on the components or on the subsystem.

Reducing Hydrogen Consumption of Hybrid Electric Vehicles Using Differential Flatness Control and Management

Energy Science &Engineering, EarlyView.
A novel Equivalent Energy Management Strategy (EEMS) is proposed to optimize the power allocation for hybrid fuel cell vehicles based on the Red‐tailed hawk algorithm and differential flatness control. The validated methodology uses the New European Driving Cycle.

Multivariate hazard orderings of discrete random vectors [PDF]

The task of comparing two random vectors with respect to some multivariate stochastic ordering usually involves an infinite number of comparisons. Dyckerhoff and Mosler (1997) proved that, when the random vectors have finite supports, this task, for some

Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

Food Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Dynamic multi‐objective optimisation of complex networks based on evolutionary computation

IET Networks, EarlyView., 2022
Abstract As the problems concerning the number of information to be optimised is increasing, the optimisation level is getting higher, the target information is more diversified, and the algorithms are becoming more complex; the traditional algorithms such as particle swarm and differential evolution are far from being able to deal with this situation ...

Decomposition of s - Concentration Curves [PDF]

For any given order of stochastic dominance, standard concentration curves are decomposed into contribution curves corresponding to within-group inequalities, between-group inequalities, and transvariational inequalities.

How Has the Health of the United States Population Changed? Evidence From Biomarkers

Health Economics, EarlyView.
ABSTRACT Population health is a central input into social welfare, but health itself is complex and multidimensional. Mapping multiple dimensions of health into a single population health index may require strong assumptions about how to aggregate and weight across dimensions.

The Impact of Economic Growth on Insurance (Growth)

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper investigates the impact of economic growth on insurance (growth), focusing on the outflow side of the insurance activity, as captured by benefits (including commissions and expenses). The findings provide evidence that economic growth does exert a positive, statistically significant impact on the benefit side of insurance (growth ...
