Simultaneously, a theoretical model boundary condition balance were established evaluate the feasibility of achieving NZE WWTPs; employed analyze data 20 conventional WWTPs China. total six can currently export excess energy, eight achieve 100% self-sufficiency by...

Algae are vital to aquatic ecosystems, with their structure and abundance influencing ecological health. However, automated detection in real water samples is hindered by complex backgrounds, species diversity, size variations. Traditional methods deemed costly species-specific, leading deep learning adoption. Current studies rely on CNN-based models limited datasets. To improve the accuracy of multiple algal real, this study collected multi-species algae from actual environments implemented...

Cooperative communications (CC) based on network coding (NC) can significantly increase the capacity of wireless networks. In this paper, we investigate how to apply NC in multi-hop networks with multiple relay nodes and sessions achieve more practical general CC NC. Based NC, consider jointly optimize node selecting, scheduling flow routing a network. We not only construct mathematical model but also formulate maximum-minimum (Max-Min) optimization problem for it. Then reformulate solve it...

As an essential building block for smart grid, the industrial internet of things (IIoT) plays a significant role in providing powerful sensing capability and ubiquitous connectivity differentiated power services. The rapid development grid imposes higher data monitoring transmission requirements terms delay energy efficiency. However, due to severe electromagnetic interference (EMI) caused by massive electrical equipment, performance IIoT becomes inferior. traditional single-hop mode evolves...

Abstract The impact of electromagnetic radiation generated by signal transmission base stations and power to meet the needs communication equipment energy consumption on environment has caused people concerns. Monitoring prediction electric magnetic fields have become critical tasks for researchers. In this paper, we propose a granularity data method based T–S (Takagi–Sugeno) fuzzy model, named rule-based which utilizing finite rules that are determined deviations between predicted values...

Games are cloned, reskinned and imitated by copying the elements of preexisting video games, even when infringing on copyrighted elements, distressing both game developers gamers introducing homogeneous games. The vagueness copyrightability rules encourages because, according to idea/expression dichotomy, generally categorized as uncopyrightable ideas. Even so, this reasoning is not same in all courts, especially jurisdictions for world’s largest two markets – China US. This article...

Abstract: This essay examines the philosophical and legal rationale underpinning criminalization of discriminatory behaviour against LGBTQ individuals, highlighting how anti-discrimination law serves as a regulatory mechanism. It explores three jurisprudential approaches: moral wrongdoing approach, individual autonomy community welfare analysing each justifies prohibition discrimination. The argues that balance between forms foundation law, ensuring intervention addresses harmful conduct...

Base on the new change of market, this paper analyze impact factors A shares and H price differences. Confirm differences under circumstances. finally obtained empirical results show that: information asymmetry factors, in liquidity risk preferences so is still significant factor changes market. In addition, selected dummy variables : Hong Kong straight train QDII as emergence 2007, that they have a certain explanatory power shares. Finally, some policy recommendations for elimination...

The construction of integrated solar storage and charging power stations has become the key issue in development new energy. effects insufficient supply, effective time, load uncertainty user evaluation during operation are comprehensively considered this paper, a safety index system based on fuzzy comprehensive theory is proposed. In order to ensure accuracy results, two-layer model used for avoid too small weight values factors. Finally, an example given prove effectiveness model.

With a large number of distributed generations connected to power systems, the structure and operation mode traditional systems are gradually changed. As an inevitable trend development future grid, energy internet has received increasing attention from governments experts, become hot topic in current researches. Furthermore, as key interface device internet, routers have characteristics unified communication interface. result, this paper researches on design based generation. The composed...

This paper investigates the wireless information surveillance in a suspicious millimeter wave (mmWave) communication system via spoofing relay based proactive eavesdropping approach. Specifically, legitimate monitor acts as to simultaneously eavesdrop and send signals vary source transmission rate. To maximize effective rate, an optimization problem for both hybrid precoding design power distribution is formulated. Since fractional non-convex, we resort Dinkelbach method equivalently reduce...

Abstract In order to improve the utilization efficiency of photovoltaic system (PV system) and battery energy storage (BESS) in integrated electric vehicle (EV) charging stations, capacity PV BESS need be allocated reasonably. this paper, maximization net annual financial value is used as objective function EV station its whole life cycle. The control strategy proposed based on time-of-use pricing. And then optimization configuration model built. economic stations compared analyzed with...

The operation and maintenance of charging discharging facilities only relies on personnel's empirical judgment based thresholds, which cannot consider the influence multiple sources. In order to solve above problem, a repository-based system for electric vehicles' is proposed. Different strategies can be provided current failure observation value set historical status vehicle facilities. inspection cycle content dynamically determined through different strategies, pertinence effectiveness...

This paper presents a system developed for on-line evaluation and verification of protection relay settings based on the advanced information computer technology. The inputs to are real-time topology operation data electricity networks from EMS, obtained relays. evaluated by simulating various faults networks. It can check sensitivity selectivity main backup settings. results then displayed in visualization window workstation. If setting value is found incorrect or inadequate, an alarm...
