1超细干法脱硫灰在水泥混凝土中的应用研究显示文摘研究了循环流化床锅炉配套干法脱硫装置再脱硫所产生的脱硫灰作为水泥掺合料的可行性。评估了干式和湿式球磨对脱硫灰的细度、成分和活性的影响。结果表明:湿磨对脱硫灰磨细更有效,磨细90 min后中位粒径约3μm,磨细对脱硫灰的成分影响不大;磨细可有效提高脱硫灰的活性,并实现超细脱硫灰替代20%波特兰水泥的胶砂早期强度与控制配方相当,28 d后胶砂强度优于控制配方,水泥混凝土在7 d后抗压强度高于控制配方,28 d抗压强度达到控制配方的120%;磨细对胶砂尺寸稳定性影响较小。苏清发 陈永瑞 Bob Jewell Tom Robl 陈宏 赖毅强 吴慕正 陈进生 2019新型建筑材料2019,46,12:4

3矿化剂硫酸钙和氟化钙作用下硅酸三钙的合成(英文)显示文摘硅酸三钙(C3S)是硅酸盐水泥和阿利特硫铝酸盐水泥熟料中重要的矿物之一。为研究C3S的特性和性能,使用CaSO4和CaF2作为矿化剂,分别在1 350、1 400和1 450℃合成了高纯度的C3S。1 350℃得到的C3S纯度高于95%,而在1 400和1 450℃合成的C3S纯度高于97%。检测结果显示3个不同温度下合成的C3S的游离氧化钙含量均小于1%。样品的化学成分分析表明,1 400和1 450℃合成的C3S中仅有痕量的SO3存在,合成过程中几乎所有的CaSO4均分解为CaO,并且与部分SiO2形成了C3S。对所有样品的X射线衍射分析结果显示,合成的C3S为M1与(或)M3型。扫描电子显微镜分析结果显示,不同温度下合成的C3S的微结构有所不同。通过差热分析对矿化剂作用下的C3S合成过程进行了分析,结果表明该合成方法与通常的C2S和CaO通过固相反应合成C3S之间存在显著差异,是一个两步合成过程。周勇敏 Tom ROBL Kevin HENKE 2014硅酸盐学报2014,42,5:2
4Towards Fully Secure 5G Ultra-Low Latency Communications: A Cost-Security Functions Analysis显示文摘Future components to enhance the basic,native security of 5G networks are either complex mechanisms whose impact in the requiring 5G communications are not considered,or lightweight solutions adapted to ultrareliable low-latency communications(URLLC)but whose security properties remain under discussion.Although different 5G network slices may have different requirements,in general,both visions seem to fall short at provisioning secure URLLC in the future.In this work we address this challenge,by introducing cost-security functions as a method to evaluate the performance and adequacy of most developed and employed non-native enhanced security mechanisms in 5G networks.We categorize those new security components into different groups according to their purpose and deployment scope.We propose to analyze them in the context of existing 5G architectures using two different approaches.First,using model checking techniques,we will evaluate the probability of an attacker to be successful against each security solution.Second,using analytical models,we will analyze the impact of these security mechanisms in terms of delay,throughput consumption,and reliability.Finally,we will combine both approaches using stochastic cost-security functions and the PRISM model checker to create a global picture.Our results are first evidence of how a 5G network that covers and strengthened all security areas through enhanced,dedicated non-native mechanisms could only guarantee secure URLLC with a probability of∼55%.Borja Bordel Ramón Alcarria Joaquin Chung Rajkumar Kettimuthu Tomás Robles Iván Armuelles 2023Computers, Materials & Continua2023,,1:0
5Stochastic Models to Mitigate Sparse Sensor Attacks in Continuous-Time Non-Linear Cyber-Physical Systems显示文摘Cyber-Physical Systems are very vulnerable to sparse sensor attacks.But current protection mechanisms employ linear and deterministic models which cannot detect attacks precisely.Therefore,in this paper,we propose a new non-linear generalized model to describe Cyber-Physical Systems.This model includes unknown multivariable discrete and continuous-time functions and different multiplicative noises to represent the evolution of physical processes and randomeffects in the physical and computationalworlds.Besides,the digitalization stage in hardware devices is represented too.Attackers and most critical sparse sensor attacks are described through a stochastic process.The reconstruction and protectionmechanisms are based on aweighted stochasticmodel.Error probability in data samples is estimated through different indicators commonly employed in non-linear dynamics(such as the Fourier transform,first-return maps,or the probability density function).A decision algorithm calculates the final reconstructed value considering the previous error probability.An experimental validation based on simulation tools and real deployments is also carried out.Both,the new technology performance and scalability are studied.Results prove that the proposed solution protects Cyber-Physical Systems against up to 92%of attacks and perturbations,with a computational delay below 2.5 s.The proposed model shows a linear complexity,as recursive or iterative structures are not employed,just algebraic and probabilistic functions.In conclusion,the new model and reconstructionmechanism can protect successfully Cyber-Physical Systems against sparse sensor attacks,even in dense or pervasive deployments and scenarios.Borja Bordel Sánchez Ramón Alcarria Tomás Robles 2023Computers, Materials & Continua2023,76,9:0
