THERMAL DEFORMATION BEHAVIOR AND FLOW STRESS MODEL OF EH40 STEEL
Published 2020-01-01“…By analyzing the curve,we find that deformation temperature and strain rate all have important effects on the dynamic recrystallization and dynamic recovery of EH40 plate steel,increasing the deformation temperature or reducing the strain rate is conducive to the occurrence of dynamic recrystallization during deformation,which contributes to grain refinement of the material. A hyperbolic sine model with ZeneHollomon parameters is adopted,the thermal deformation equation,activation energy of thermal deformation,and mathematical model of Z parameters were obtained. …”

Multi-stage hashing network storage structure for intelligent routing
Published 2020-10-01“…Network data collection and storage are fundamental for intelligent routing control,providing massive flow data for model training and decision-making.However,as the key device in network storage system,switches have very limited memory size and design flexibility,which can’t satisfy the needs of intelligent routing control for comprehensive high-precision data and lightweight storage system,thus reducing the effectiveness of intelligent routing control.A multi-stage hashing network storage structure (MHNSS) was proposed for intelligent routing control,which fully utilized the limited memory resource of switch and completed network data storage with low collision rate.The number of candidate buckets of the flow key was augmented by multi-stage hash table,thus reducing collision rate and improving memory load ratio.Hash collision was resolved via coarse-grained timestamp LRU algorithm,which always stored most recently used data and cleared least recently used data to avoid subsequent collisions as far as possible.Trace-driven experiments showed that compared with widely used single hash table,MHNSS had significant performance advantage in collision rate and load ratio.…”

Private data access control model based on block chain technology in the internet of things environment
Published 2022-12-01“…The traditional “centralized” access control technology can no longer guarantee the security of private data access control in the current internet of things environment.Based on the ABAC (attribute-based access control) model, a blockchain based access control framework for the internet of things and a private data access control model were proposed.Firstly, the basic framework and process of access control were described and analyzed in detail, and an auditable access control model was proposed to systematically manage the access control policies of private data through the requests, responses and access records stored in the blockchain network.Then, an auditable access control system based on blockchain technology was proposed, which can provide distributed, fine-grained and dynamic access control management in the internet of things, realize the effective management and auditable access to data, and adopt the access control method based on smart contract to realize the transparent, traceable and automatic access control over the internet of things resources.Finally, simulation experiments and performance tests verify the effectiveness and security of the access control model and system.…”
