Better monitoring and control of energy consumption and effective use of performance indicators are of utmost important for achieving improved energy efficiency performance in manufacturing for current and future enterprises. This paper aims at analyzing the current state of the art on energy related production performance indicators to derive research gaps and industrial needs in the area. The...

Abstract In recent years, there has been growing interest in defining what exactly constitutes “decent living standards” (DLS)—the material underpinnings of human well-being. We assess the gaps providing decent health, shelter, nutrition, socialization, and mobility within countries, across world. Our results show that more people are deprived DLS than income-poor, even when numbers measured ag...

Abstract We study the minimal gap statistic for sequences of form $\left( \alpha x_n \right)_{n = 1}^{\infty}$ where is a sequence real numbers, and its connection to additive energy 1}^{\infty}$. Inspired by recent paper Aistleitner, El-Baz Munsch we show conditionally on Lindelöf Hypothesis that if lowest possible order then almost all α, $\delta_{\min}^{\alpha} (N) \min \left\{\alpha x_m - \...

We investigate electronic transport in lithographically patterned graphene ribbon structures where the lateral confinement of charge carriers creates an energy gap near the charge neutrality point. Individual graphene layers are contacted with metal electrodes and patterned into ribbons of varying widths and different crystallographic orientations. The temperature dependent conductance measurem...
