In this study, an open-cut approach using steel-sheet piles and jet grouting for waterproofing was proposed to resolve the problem that ordinary pipe-jacking equipment cannot cross areas with existing anchor cables in soft stratum. The case history of a project sewage treatment plant Jinan East Railway Station area investigated. mechanical properties piles, horizontal displacement ground surface settlement anchor-cable crossing were investigated based on situ observations. Numerical...
In order to enhance the cyber-security of networked control systems, Kogiso and Fujita (2015) proposed a concept controller encryption using homomorphic for first time. Encrypted linear controllers scheme could conceal information processed inside device maintain original functions controllers. this paper, we propose encrypt BGN encryption, which supports addition multiplication. We also compare efficiency with an encrypted RSA Paillier encryption.
Electric heat treatment is a widely used concrete curing method during the winter. Through direct and indirect exchange, electric heating system tracks controls temperature of medium based on positive coefficient (PTC) effect. In this study, to standardize application in winter concrete, thermal energy conversion an heat-transfer characteristics have been studied. Based theoretical derivation, calculation model relationship between established. The verified using test results. numerical...
As the composite pile, precast concrete piles reinforced with cement-treated soil (PCCS) is formed by driving cement (PC) pile into deep mixing (DM) column, which has been successfully and widely utilized to support buildings embankments over soft soil. To increase spacing give full play economic merits of PCCS, a reinforcement scheme, involves combined use rigid flexible columns, employing penetrated PCCSs floating DM columns proposed for ground treatment. However, there lack feasible...
When heat energy is transferred to concrete through conversion by an electric heating system, the overall thermal performance of early-age affected local high temperature concrete. This, in turn, affects accuracy prediction and calculation deformation. Concrete physical parameter models considering mutual influence humidity were established clarify tracing system on transfer at early age, based concepts equivalent age hydration degree. Additionally, COMSOL numerical simulation software was...
The object of the study is samples food powders obtained by grinding products collection and processing a number grain crops, using air-grinding technology in an improved jet mill. One most important problems modern industry that for production flour from cereals endosperm used while nutrients are found shells germ grain. As result its conventional mills, common at existing large pieces bran variation particle size obtained, this method energy-intensive. According to authors, best solution...
