In the global push to cut carbon emissions, liquefied natural gas (LNG) is increasingly valued as a clean and efficient energy source. Maritime transport crucial for LNG trade. This study utilizes AIS data complex network analysis discover:(1) Overall, maritime trade has consistently grown, showing regional concentration of supply demand. Despite uneven node degree distribution, remains stable. (2) Regionally, becoming more diverse, with multiple subgroups indicating strengthening...

Recently some new models based on Pythagorean fuzzy sets (PFSs) have been proposed to deal with the uncertainty in multiple attribute group decision making (MAGDM) problems. In this paper, considering linguistic variables and entropic, we propose a trapezoidal entropic combined ordered weighted averaging operator solve MAGDM Next, study main properties by utilizing operational laws of variables. Finally, numerical example concerning enterprise location is given illustrate practicality...

Entropy, a basic concept of measuring the amount information and degree confusion, has been applied in many weighted averaging operators linguistic group decision making. In paper, we construct an intuitionistic fuzzy entropy based on variable. Then, inspired by operations concentration dilation (De SK, Biswas R, Roy AR, Fuzzy Sets Syst. 2000;114(3):477ȓ484), extend to interval-valued entropy. After that, entropic combined (IFIVLECWA) operator is proposed for multiple attribute Finally,...

Preference relations (PRs) as useful and efficient information description tools have been widely applied in practical multiple-attribute group decision-making (MAGDM) problems. Due to fuzziness complexity of problems, the limitations experts' professional knowledge experience, provided PRs are usually inconsistent, will lead unreasonable conclusion. Consequently, we define concept trapezoidal Pythagorean fuzzy linguistic (TrPFLPRs), a method for confirm consistent repair inconsistent PFs...

Honeypots have been widely used in the security community to understand cyber threat landscape, for example study unauthorized penetration attempts targeting industrial cyber-physical systems (ICPS) and observing behaviors such activities. However, some better-resourced attackers may attempt identify honeypots develop strategies compromise them, aka anti-honeypot. In this paper, we present an anti-honeypot enabled optimal attack strategy ICPS, by employing a novel game-theoretical approach....

Bonferroni mean (BM), one of the desirable operators that can capture expressed interrelationship among individual arguments. Moreover, Pythagorean fuzzy sets (PFSs) have been proved extremely effective for modeling uncertainty Multi-attribute decision making (MADM) problems. In this paper, we present a new extension linguistic term called triangular variables (PTFLVs) and operational laws. Then, further introduce BM into environment develop (PTFLBM) operator weighted PTFLBM operator....

Federated learning-based navigation has received much attention in vehicular IoT. The intention is to employ a big number of end-users for data collection along different trajectories and perform local training global learning model substitute the positioning system (GPS) urban areas. prerequisites its commercialization, however, lie location-dependent input trustworthiness participants' privacy preservation. In this paper, we propose privacy-preserving proof-of-location mechanism using...

In this paper, a modified Polak–Ribi'ere–Polyak (MPRP) conjugate gradient method for smooth unconstrained optimization is proposed. This produces at each iteration descent direction, and property independent of the line search adopted. Under standard assumptions, we prove that MPRP using strong Wolfe conditions globally convergent. The results computational experiments are reported show effectiveness proposed method.

Hydrogen is a valuable gas as clean energy source and feedstock for some industries. Therefore, demand on hydrogen production has increased considerably in recent years. Food waste an important part of urban living garbage,which full organic matter easy to be degraded. So, biological from food fermentation significant advantages providing inexpensive generation help meet the needs carbon emission reduction with simultaneous treatment. This article reviews following aspects: mechanism...

In this paper, the performance of constructed rapid infiltration system ( CRI ) for removal organic pollutants domestic sewage was investigated. The results showed that had higher efficiency COD Cr removal. rate 86.1% by without carbonized sludge , 91.8% with sludge. overcomes disadvantage traditional wastewater land treatment RI hydraulic load is low, but retains advantages solution process are low cost, ease processing, less energy consumption and good water quality.

This paper designed and investigated the pyrolysis combustion process of sewage sludge, based on properties self-sustained conditions sludge. The water content sludge was first reduced to less than 55% through mechanically dewater. Then, combusted in pyrolysis-combustion chain grate stoker. A system designed, with processing capacity 15 tons sawage per day. results pilot test show that a dynamic equilibrium reached among drying, pyrolysis, gasification process. In addition, emission...

This paper described the structure and working principle of porous window based on unsaturated media evaporative refrigeration. The method standardization for calculating evaluating performance have been put forward. influences environmental parameters heat transfer coefficient refrigeration placed slope roof flat are investigated by numerical simulation. calculation results show that refrigerating is better than roof. At same time, It pointed out beneficial building energy efficiency.

In this paper, we investigate the issue of convergence error consensus based algorithm for economic dispatch problem (EDP) in smart grid, where incremental cost (IC) acts as variable.

We consider case minimizing subject a fixed cardinal number and size given bound. By formulating them corresponding...

The 19th session of national congress the communist party China reaffirmed its determination to win fight against poverty. Therefore, it is great importance determine how help people in different poverty-stricken areas. Bonferroni mean (BM), which can capture interrelationship among individual arguments. And intuitionistic preference relation a powerful express decision makers' information over criteria process making. Hence, this paper, we present weighted trapezoidal Pythagorean fuzzy...
