Blockchain is a point-to-point distributed ledger technology based on cryptographic algorithms. However, the open and transparent blockchain supplemented by statistical methods such as sociological mining data has caused users' privacy to face major threats. Therefore, protection become focus of current research. Ring signature commonly used encryption in field protection. this paper constructs scheme ring signature. This solution built storage protocol elliptic curve, complete anonymity...
Controlling wastewater pollution from centralized industrial zones is important for reducing overall water pollution. Microbial community structure and diversity can adversely affect treatment plant (WWTP) performance stability. Therefore, we studied microbial structure, diversity, metabolic functions in WWTPs that treat or municipal wastewater. Sludge richness were the lowest WWTPs, indicating influents inhibited bacterial growth. The sludge of WWTP had low Nitrospira populations, influent...
Software Defined Networking (SDN) centrally manages the network data layer to improve programmability and flexibility of networks by controller. Because centralized control, SDN is vulnerable Distributed Denial Service (DDoS) attacks. In order protect security SDN, a method based on K-means++ Fast K-Nearest Neighbors (K-FKNN) proposed for DDoS detection in modular system presented The detailed experiments are conducted evaluate performance. results show that K-FKNN improves accuracy...
Since the Internet of Things (IoT) applications today employ many different sensors to provide information, a large number Bluetooth low energy (BLE) devices will be developed as part IoT systems. The low-power and low-cost requirements all BLE nodes are among most challenging issues when supporting neighbor discovery process (NDP) for such devices. parameter settings essential achieve required performance NDP, configuration method in can beneficial determining some critical metrics,...
Coal and gas outbursts are great natural disasters in underground coal mines, seriously threatening the lives of miners mine safety. The study relationship between geological structures has always been an important component work, it also serves as a foundation for mines to develop outburst prevention measures. This considers groups F E seams, mainly mined southwest wing Likou syncline Pingdingshan mining area, research object. Based on actual data, this investigates distribution intensity...
To cope with the arbitrariness of network delays, a novel method, referred to as composite particle filter approach based on variational Bayesian (VB-CPF), is proposed herein estimate clock skew and offse... | Find, read cite all research you need Tech Science Press
Abstract In recent years, the Internet of things (IoT) equipment has grown rapidly, and scale IoT also expanded. The is deployed in system a centralized manner. At same time that massive data put certain amount pressure on storage, open network environment not fully protected privacy data, which become one important factors restricting development IoT. Blockchain point‐to‐point distributed ledger technology based cryptographic algorithms. characteristics decentralization, tamper resistance,...
The multi-compartment vehicle routing problem (MCVRP) has been applied in fuel or food delivery, waste collection, and livestock transportation. Ant colony optimization algorithm (ACO) recognized as an efficient method to solve the VRP its variants. In this paper, improved hybrid ant (IHACO) is proposed minimize total mileage of MCVRP. First, a probabilistic model designed guide search towards high-quality regions solutions by considering both similar blocks customers customer permutations....
This research aimed to determine the characteristics of motor vehicle exhaust emissions in plateau area. The PM2.5 was evaluated Caohai Tunnel Kunming for this study by measuring water-soluble inorganic ions, carbonaceous species, polycyclic aromatic hydrocarbons (PAHs), and elements air samples. results showed that mass concentration tunnel about 225.65-312.84 μg·m-3, which is 11-14 times ambient atmosphere. species were most abundant constituting 35.73% total PM2 5 mass, followed 21.78%...
Understanding gas desorption effects and laws of coal mass under different conditions is essential for the effective exploration emission in underground mines, prediction prevention outburst, accurate detection [coal methane (CBM)] content seams, CBM productivity. Using a self-developed test platform, we simulated adsorption performed physical simulation tests. Based on these tests, investigated differences total amount desorbed, rate, initial desorbed by long-flame coal, coking meager-lean...
The localization of anchor-free wireless sensor network’s serious cumulative error leads to low positioning accuracy. To solve this problem, paper proposed a co-located method based on asynchronous change learning factor adaptive weights particle swarm optimization algorithm (SAAPSO) and Taylor algorithm. first phase is building relative coordinate system. second estimating the node’s initial position with SAAPSO using iterative calculate in obtain accurate result. In third stage, node...
