Existing studies examined the U.S.'s direct GHG emitters and final consumers driving upstream emissions, but overlooked primary suppliers enabling downstream emissions relative contributions of socioeconomic factors to emission changes from supply side. This study investigates sectors in U.S. production-based (direct emissions), consumption-based (upstream driven by consumption products), income-based (downstream enabled inputs sectors) viewpoints. We also quantify US's during 1995-2009 both...

Aiming at the accuracy of modeling in existing integrated energy system planning methods, a comprehensive p lanning method that takes into account actual operating efficiency is proposed. First, output model various equipment units based on basic structure established. Then, traditional hub model, correction for work to construct an improved dynamic With goal minimizing cost system, operation characteristics Finally, proposed this paper verified through simulation. The results show that:...

The authors construct a tripartite evolutionary game model that considers renewable energy, traditional coal-fired power plants, and market users. We propose multiple income matrices under different strategies, conduct stability analysis, form series of assumptions meet the game. also simulate analyze impact key factors—such as assessment costs, pricing behaviors electricity prices green demand—on In addition, equilibrium points can be achieved by optimizing trading strategies their...

The performance of Global Navigation Satellite System (GNSS) and Inertial (INS) integrated navigation can be severely degraded in urban canyons due to the non-line-of-sight (NLOS) signals multipath effects. Therefore, achieve a high-precision robust system, real-time fault detection localization algorithms are needed ensure integrity. Currently, residual chi-square test is used for positioning domain, but it has poor sensitivity when faults disappear. Three-dimensional (3D) light ranging...

This study aims to enable intelligent structural health monitoring of internal damage in aerospace components, providing a crucial means assuring safety and reliability the field. To address limitations assumptions traditional methods, carbon nanotube (CNT) yarn sensors are used as key elements. These woven with fiber yarns using three-dimensional six-way braiding process cured resin composites. optimize sensor configuration, an artificial fish swarm algorithm (AFSA) is introduced,...

The single-phase grounding fault of power systems is influenced by a variety factors, resulting from the developing sizes and increasing complexity systems. In order to take advantage big data in systems, we propose revised method with use synchronized phasor measurement. data-driven designed detect localize fault, which reveals correlation between eigenvalues status First, it calculates contribution each node; then combines split window monitor real time more efficiently. Based on elements...

Purpose In response to the 2008 financial crisis, performance of Chinese construction industry seems be more successful, especially in total factor productivity growth (TFPG) and its contribution (TFPGC). Hence, purpose this paper is investigate reveal potential successful lessons regard. Design/methodology/approach This study conducted innovatively based on a special comparative analysis TFPG TFPGC between pre- post-2008 crisis. Solow Residual Approach used measure for period 2002–2016....

Radio frequency interference (RFI) can have adverse effects on commercial electronics. Current properties of high-performance integrated circuits (ICs), such as very small feature sizes, high clock frequencies, and reduced voltage levels, increase the susceptibility these to RFI, causing them be more prone smaller RFI levels. Besides, recent developments mobile devices wireless networks create a hostile electromagnetic environment for ICs. Therefore, it is important generalize ICs RFI. In...

In view of the current situation that new generation smart grids with “double high” characteristics is in urgent need effective state evaluation methods due to strong volatility and diverse demands, a method operation distribution networks based on free probability theory proposed, which combined high-order moment indexes describe trajectory from data-driven perspective. First, assessment problem modeled as binary hypothesis testing problem, asymptotic equation established provide framework...

Voltage decrease and power loss in distribution lines of aircraft electric system are harmful to the normal operation electrical equipment, may even threat safety aircraft. This study investigates how gap distance (the between cables skin) voltage frequency (variable supply will be adopted for next generation aircraft) affect impedance cables. To more precise, forming mechanism cable resistance inductance is illustrated detail their change trends with analyzed help electromagnetic theory. An...

It is a challenge to distinguish between different cloud types because of the complexity and diversity coverage, which significant clutter source that impacts on target detection identification from images space-based infrared sensors. In this paper, novel strategy for classification in wide-swath passive sensor developed, aided by narrow-swath active data. The consists three steps, is, orbit registration, most matching donor pixel selection, type assignment each recipient pixel. A new...

In this paper, we established a rating charge model of transfer tax (RCTT) to solve transboundary air pollution control problem China. Firstly, by using the bi-level nonlinear programming model. model, leader is China's central government and followers consist 31 provinces. The aims decrease nation's total pollutant costs, whereas each province attempts minimize its costs balancing own reduction cost with or from other provinces, in context rate set leader. Then, used SO2 amount Beijing,...
