Article
Microbial induced corrosion (MIC) is an increasing challenge in concrete wastewater conveyance systems. Preventing MIC usually requires a corrosion-resistant chemical/antibacterial coating on cement-based materials. This study investigated the effects of electroless plating time and temperature on the preparation of the Cu-plated hardened cement pa...
Article
Electrodeposition of Cu2O on the concrete surface was applied to protect the concrete sewers from microbially induced corrosion. The effects of deposition time, current density, and electrolyte type and concentration on the antimicrobial properties of the Cu2O-electrodeposited mortar specimen were investigated. X-ray diffraction analysis and scanni...

To measure semantic similarity between words, a novel model DFRVec that encodes multiple semantic information of a word in WordNet into a vector space is presented in this paper. Firstly, three different sub-models are proposed: 1) DefVec: encoding the definitions of a word in WordNet; 2) FormVec: encoding the part-of-speech (POS) of a word in Word...

Replay speech answer-sheet detection is an urgent problem to be solved for intelligent language learning system. Traditional features used in replay speech detection are often extracted from power spectrum. However, power spectrum may not be the optimal spectrum to extract feature for replay speech answer-sheet detection because it doesn’t consider...
Article
To further improve the mechanical properties of the Ti(C,N)-TiB2-Co cermets prepared by in-situ reaction hot pressing, the TaC and WC were added in Ti-C-BN-Co system. The effect of varying TaC/(TaC + WC) weight ratio on the microstructure and mechanical properties of the cermets was studied by scanning electron microscope, X-ray diffraction, and te...

Deceptive reviews on Web are a common phenomenon and how to detect them has a very important impact on products, services, and even business policies. In order to filter out deceptive reviews more accurately, a new model called Sentence Joint Topic Sentiment Model (SJTSM) is presented in this paper, which incorporates the sentence structure of revi...

The incorporation of WC promotes the sintering and grain refinement of Ti(C, N)-based cermets, leading to superior mechanical and functional properties. Herein, we present the reaction process of Co–Ti–C–BN–WC system and influence of WC content on microstructure and mechanical properties of Ti(C, N)-based cermets. The results reveal that Ti(C, N) i...
Article
This study investigated the stability of bound chloride ions in the cement mortars incorporating supplementary cementitious materials (SCM) during the electrochemical chloride extraction (ECE) process. The effect of the replacing ratio of fly ash (FA) and silica fume (SF) and sulfate concentration on the chloride binding and distribution after ECE...
Article
Destabilization and release of bound chloride ions in reinforced concrete structures can cause accelerated corrosion of steel bars, posing an attendant risk to the durability of the whole structure and this problem is exacerbated by the combined effect of SO4²⁻ and electric field. In this paper, electrochemical chloride removal (ECR) method was use...

Nowadays, speaker disguise is a common operation that presents a great challenge to social security. Therefore, it is important to recognize the authenticity of speech. Most of the current researches focus on speech spoofing, which simulates a target speaker to break through the state-of-art ASV systems by increasing false acceptance rate. Meanwhil...

Ti(C,N)-TiB 2 -Co cermets were in situ synthesized, via reactive hot pressing from the Co-Ti-C-BN system, with a Co content ranging from 6 to 22 wt%. The microstructure, relative density, hardness, and fracture toughness of the sintered compacts was investigated by light microscopy, scanning electron microscopy, ceramic densitometry, and Vickers ha...
Article
The electro-deposition technique can be used to repair cracks in reinforced concrete. Inevitably, this treatment affects the physical and chemical properties of the reinforced concrete. However, scant research has focused on the effect of electro-deposition on the microstructures of concrete. This study investigated the changes in the compositions...

The phase formation mechanism of Ti(C,N)–TiB2–Co composite cermets during the reactive hot-pressing process was investigated by delicate microstructure and phase analysis of Co–Ti–C–BN powder compacts sintered at different temperatures. The results showed that Ti–BN and Co–Ti solid diffusion reactions occurred. As the sintering temperature was incr...

Constructing a robust appearance model of the visual object is a crucial task for visual object tracking. Recently, more and more studies combine spatial feature with temporal feature to improve the tracking performance. These methods successfully apply the features from spatial and temporal to address the problem for tracking. This paper presents...
Article
Destabilization and release of bound chlorides in reinforced concrete structures (RCS) cause accelerated corrosion of steel bars, posing an attendant risk to the durability of the whole structure. This problem is exacerbated by an aggressive environment where chloride and sulfate coexist, and stray current is present, which are commonly observed fo...
Article
The performance of the tracking task directly depends on target object appearance features. Therefore, a robust method for constructing appearance features is crucial for avoiding tracking failure. The tracking methods based on Convolution Neural Network (CNN) have exhibited excellent performance in the past years. However, the features from each o...

Mining1 frequent web page sets from web log can help to understand the behaviors of users. In this paper, weight is assigned dynamically with the dwelling time of users on different pages to mine weighted frequent page sets (WFPS), and a filtering strategy is introduced to eliminate page sets which are impossible to be weighted frequent. An improve...
