Using panel data from China’s tobacco manufacturing industry 2014 to 2018, the DEA-Malmquist method is used measure green total factor productivity of on basis comprehensive consideration environmental pollution and energy consumption. The study found that Malmquist index basically showed a fluctuating upward trend; technical level 2014-2017 needs be improved, 2017-2018 has begun improve.

steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. moreover, it is an interface between the diver and vehicle. fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. this paper addresses the fault detection and reconstruction in automotive elect...

The wheel-rail-sleepers system is simulated as a series of moving point loads on an Euler–Bernoulli beam resting on a visco-elastic half space. This paper concentrates on the railsleepers interaction system (railway system) and the fault detection. The main objective is to mathematically develop and implement a dynamic model of a railway system then the diagnosis of system defects using a Luenb...

The sensorless DTC of Brushless AC (BLAC) machine using Luenberger observer is proposed in this paper. In Direct Torque Control (DTC), accurate rotor position information is not essential. The speed is estimated by Luenberger observer, which used to improve the performance of dynamic tracking and accuracy of the whole system. The speed regulation is realized by a conventional PI regulator. Simu...

We obtain a robust, non-parametric, estimate of the Hub-ble constant from galaxy linear diameters calibrated using HST Cepheid distances. Our method is independent of the parametric form of the diameter function and the spatial distribution of galaxies and is insensitive to Malmquist bias. We include information on the galaxy rotation velocities ; unlike Tully-Fisher, however, we retain a fully...

The Green Deal policy and Sustainable Development Goals require that the economic development of a country should be reoriented towards ‘green‘ development. Currently, globalisation intensification production boosts urbanisation in many countries, which may stimulate growth improve citizen well-being, but also lead to excessive consumption resources negative environmental impacts. Against backd...

Economic development in China has been severely restricted by environmental problems such as carbon emissions. Improving green total factor productivity (GTFP) is an extremely important pathway to realizing peak and neutrality. Nevertheless, existing studies on China’s urban GTFP under the emissions constraint are still insufficient. In this context, study adopts directional distance function (...

Introduction: Enhancing the green total factor productivity of dairy cows (GPDC) is crucial for fostering low-carbon sustainable development industry. Methods: This research utilizes Minimum distance to weak efficient frontier–Meta frontier–Malmquist–Luenberger (MinDW-MML) index examine GPDC using unbalanced panel data on in 26 provinces China from 2004 2020, taking into account regional hetero...

Green development and the high-quality economic growth model have replaced extensive in an effort to reduce large amounts of energy consumption pollution emissions. total factor productivity has become important indicator more accurately measure quality growth. Transportation infrastructure is a fundamental component that may effectively integrate regional resources, increase cooperation, encou...

The main objective of this study was to apply the non-parametric method of Data Envelopment Analysis (DEA) to measure the efficiency of Greek NHS hospitals between 2009-2013. Hospitals were divided into four separate groups with common characteristics which allowed comparisons to be carried out in the context of increased homogeneity. The window-DEA method was chosen since it leads to increased...
