Phthalate esters (PAEs) are an emerging pollutant due to widespread distribution in environmental mediums that have attracted attention over recent years. However, there is little information about tea plantation soil PAEs. A total of 270 samples collected from 45 plantations the major high-quality tea-producing regions Jiangsu, Zhejiang, and Anhui provinces China were analyzed for seven The detection frequency PAEs was 100%. DBP, DEHP, DiBP main congeners soil. concentrations upper...

While variable renewable energy (VRE) has been developed for decades, VRE market participation is developing relatively slowly, despite the potential economic efficiency it may bring. This paper tries to specify of in a deregulated pool-based electricity market. Based on standard design, this built direct current optimal power flow (DC-OPF) based simplified 2-settlement spot model conjugating and ancillary service clearing. To address outcomes imperfect real world, studied consequences...

As the penetration rate of variable renewable energy such as wind power increases in system, composition and balance system also change gradually. The intermittency poses great stability challenges to traditional centralized generation load-oriented transmission distribution methods. Therefore, Active Distribution Network Operator (ADNO) with distributed installation at local level has a good application prospect new scenario. However, ADNO needs improve its operational efficiency based on...

To identify a city's PV roof resources, the area and ownership distribution of residential buildings in an urban district should be assessed. achieve this assessment, remote sensing data analysing is promising approach. Urban building estimation major topic for image information extraction. There are normally three ways to solve problem. The first way pixel-based analysis, which based on mathematical morphology or statistical methods; second object-based able combine semantic expert...

Traditional stochastic dominance rules are so strict and qualitative conditions that generally a relation between two alternatives does not exist. To solve the problem, we firstly supplement definitions of almost (ASD). Then, propose new definition degree (SDD) is based on idea ASD. The takes both objective mean stakeholders’ subjective preference into account, can measure standard degree. contains four kinds SDD corresponding to different stakeholders (rational investors, risk averters,...

Opportunism behavior is an important factor that affects the outcome of a construction engineering project.But this often ignored in field.This paper studied effect opportunism on projects based evolutionary theory.Firstly, explained mechanism and consequences perspective game theory.Secondly, building model to describe agent single population.The result shows may spread agents rule out hornist agents.This suggests should be properly treat so as guarantee projects.
