Decentralized finance, i.e., DeFi, has become the most popular type of application on many public blockchains (e.g., Ethereum) in recent years. Compared to traditional DeFi allows customers flexibly participate diverse blockchain financial services lending, borrowing, collateralizing, exchanging etc.) via smart contracts at a relatively low cost trust. However, open nature inevitably introduces large attack surface, which is severe threat security participantsfunds. In this paper, we...
Accurate fault identification is the key to realizing diagnosis and condition monitoring of aero-engines. Aero-engine rotor systems work in high-temperature, high-speed high-pressure environments. It extremely prone failure. In this article, a system method based on multi-source information fusion graph convolutional network (MSIF-GCN) proposed. Firstly, simulation test bed for center rod-fastened aero-engines was built. Experiments with different states were carried out bed. The...
Recently answers for fact lookup queries have appeared on major search engines. For example, the query Barack Obama date of birth Google directly shows "4 August 1961" above its regular results. In this paper, we describe FACTO, an end-to-end system answering web search. FACTO extracts structured data from tables web, aggregates and cleans such stores them in a database. Given query, will decide if it asks facts database, provides most confident answer when possible. achieves higher...
The diatom test is a forensic technique that can provide supportive evidence in the diagnosis of drowning but requires laborious observation and counting diatoms using microscopy with too much effort, therefore it promising to introduce artificial intelligence (AI) make process automatic. In this article, we propose an solution based on YOLOv5 framework for automatic detection recognition genera. To evaluate performance AI different scenarios, collected five lab-grown genera samples some...
As traditional recommendation systems ignore the hidden information among different user behaviors (such as clicks, add-to-favorites, add-to-cart, and purchases), this often leads to low accuracy in results. We propose a meta-graph network system via multi-behavior encoding (MBGR). Firstly, graph convolutional neural is used extract features from various interactive behavior heterogeneous graphs of user-items for modeling. Secondly, matrix decomposition algorithm meta-knowledge learner are...
To solve the problem of information overload in field news, this paper designs and implements a feasible news recommendation system, where front-end web page is made by Django framework, whose performance optimized bootstrap jquery, while back-end design, original user similarity calculation method improved adding time attenuation factor, model based on collaborative filtering (CF) algorithm proposed. Experimental results show that proposed achieves highest recall, accuracy, F1 score ratio...
This study examined the relationship between physical exercise (PE) and prosocial behavior (PSB) constructed a chain mediation model through mediating effect of education learning motivation (PELM) emotional intelligence (EI).Through stratified random sampling, 1053 students (average age = 14 years, SD 0.96 years) that complied with requirements were surveyed from Henan Province in China. PE, EI, PELM, PSB assessed using standard scales. For data analysis, Pearson's correlation structural...
We present Chios, an intrusion-tolerant publish/subscribe system which protects against Byzantine failures. Chios is the first achieving decentralized confidentiality with fine-grained access control and strong publication order guarantees. This in contrast to existing systems much weaker security reliability properties. flexible modular, consisting of four fully-fledged configurations (each designed meet different goals). have deployed evaluated our on Amazon EC2. compare various systems....
Aiming at the urgent need for a cross-domain authentication scheme with low computational cost, latency, and high security in edge computing environment, this paper proposes blockchain-based protocol. In protocol, IoT devices environment themselves control generation, encrypted storage, registration, use or cancellation of their identities, authenticity credibility these identities can be guaranteed through trusted identity checking mechanism. The public information is shared among nodes...
With the development and application of digital technologies such as artificial intelligence, big data 5G, literacy has become core element important requirement college students' literacy. In current era, strengthening cultivation its intrinsic value: it is inevitable for survival society, prerequisite improving whole people, choice realizing strategic construction goal China. order to promote literacy, this paper constructs path from perspective activity theory, which composed subject...
The advent of the big data era, rapid development mobile internet, and rising demand cloud computing services require increasingly more compute capability from their center. This increase will most likely come higher rack room power densities or even construction new Internet centers. But an in a center’s business-critical IT equipment (servers, hubs, routers, wiring patch panels, other network appliances), not to mention infrastructure needed keep these devices alive protected, encroaches...
With the advent of big data and cloud computing solutions, enterprise demand for servers is increasing. There especially high growth Intel based x86 server platforms. Today’s datacenters are in constant pursuit performance/high availability solutions coupled with low power consumption heat generation ability to manage all this through advanced telemetry gathering. This paper showcases one such solution an updated rack architecture that promises improvements. The center cooling more...
