Shrinkage during hardening and curing is one of the largest challenges for widespread application metakaolin-based geopolymers (MKGs). To solve this problem, a silane coupling agent (SCA) waterborne epoxy resin (WER) were used to synthesize MKG composites. The individual synergistic effects SCA WER on chemical, autogenous, drying shrinkage assessed, modification mechanisms investigated by microstructural characterization, resistance was evaluated chloride ion permeability composite coatings....
利用电化学方法在碱性条件下电解石墨棒, 通过常温下水合肼还原, 得到5~10 nm的荧光石墨烯量子点(Graphene Quantum Dots, GQDs). 通过透射电子显微镜(TEM)、原子力显微镜(AFM)对所制备的GQDs进行形貌表征, GQDs的粒子大小均一, 为单层石墨烯. 通过傅里叶变换红外光谱(FTIR)、荧光光谱(PL)、紫外可见吸收光谱(UV-vis)、X 射线衍射光谱(XRD)对所制备的GQDs进行性质测定, 发现GQDs可以发出黄色荧光, 量子产率为14%, 毒性低、具有良好的水溶性、荧光稳定性和生物兼容性, 可顺利进入细胞, 在肿瘤细胞的成像研究方面具有广泛的应用前景.
We consider the joint design of transmit waveform and receive filter in multiple-input multipleoutput space-time adaptive processing (MIMO-STAP) radar for detecting slow-moving targets presence interference (clutter jamming). The with two sequence constraints is addressed due to potential advantages, such as better clutter suppression, weak target detection, spectral compatibility. formulate an optimization model relying on maximization Signal-to-interference-plus-noise-ratio (SINR) under...
Driven pile has often been used to provide loading support for civil infrastructure, but the induced ground vibration can cause damage adjacent structures. The risk associated with driving is managed via monitoring vibrations that quantified by peak particle velocity (PPV). Therefore, a rational approach predict PPV desired because commonly scaled-distance equations consider only distance from driven piles and input energy ignore other important factors. To fulfill this knowledge gap, finite...
Driven piles have often been used in many civil infrastructures to provide structural loading support. However, the inevitable vibrations induced during pile driving processes may cause varying degrees of damage adjacent structures. One common risk management measures by state DOTs is monitor actual surrounding grounds driving. currently there a lack well-established procedure or specification determine size ground vibration monitoring area. In this study, statistical was developed...
The paper analyses the impact of: 1) CO2 pricing; 2) using biodiesel on multimodal freight transport system in and through Netherlands taking changes demands for road, rail, inland waterway into account. Special attention is given to market share of various barge classes transport. This presents GIS-based flow estimation model which applied scenario analysis simulate, visualise, evaluate impacts tested policies. shows that pricing limited terms both reducing emissions realising modal shift....
Traffic accidents are closely related to the level of drivers’ safe driving skills. Many countries will add evaluation quality suitability. Safe refers driver’s own ideological quality, psychological and innate physiological which have an important impact on safety work. Including: awareness compliance with traffic laws regulations, strong sense responsibility, agility in responding sudden dangerous situations, whether ability judge road conditions is keen, character, personality, emotion,...

This paper investigates the early reaction, dissolution, characteristics composite geopolymer binders that include fly ash, calcium aluminate cement (CAC), silica fume (SF). were analysed by using isothermal calorimetry, inductively coupled plasma optical emission spectrometry (ICP-OES) scanning electron microscopy (SEM). All starting materials...
Abstract With the increasing dredging activities, a large quantity of silt is removed from bottom waterbody and dumped on landfill site, having potential to cause number environmental issues. Given that dredged soft weak soil, it usually stabilized with ordinary Portland cement (OPC) and/or lime for application in construction. However, production processes traditional stabilizers are energy intensive high CO2 emission. In this study, attempts being made find an alternative environmentally...
Quorum sensing is widely distributed in bacteria and make are similar to complex adaptive systems, with intelligent features such as emerging non-linear, the ultimate expression of changes environment. Based on phenomenon bacterial quorum Bacterial Foraging Optimization Algorithm, some new optimization algorithms have been proposed.

Oil-water dispersed flow, in which one of the phases either water or oil is into other phase, continuous occurs commonly Petroleum Industry during production and transportation crudes. Phase inversion when phase grows becomes caused by changes composition, interfacial properties factors. Production equipment, such as pumps chokes, generate shear oil-water mixture has a strong effect on phenomena. In this study, based newly acquired data gear pump, relationship between region intensity are...
In this paper, a novel method is investigated to detect short-circuit fault signal transmission lines in strong noise environment based on discrete wavelet transform theory. Simulation results show that the can accurately determine position, effectively analyze non-stationary and be suitable for line occurred after transient detection. Furthermore, it eliminate effects of so as realize accurate fault.
Large inventory and non-degradability made waste glass fiber reinforced plastics (GFRP) a heavy burden to environment. They are increasingly reclaimed through mechanical crushing used as aggregate replacement in concrete. However, reuse of all-component recycled GFRP (rGFRP) was still limited due the inconsistent influences powder on cementitious materials. In this study, mortar concrete with two different gradations rGFRP at 10 wt%, 20 wt% 30 were investigated tests, ultrasonic pulse...
