On corrosion to stainless steel by calcium chloride with different extender

Lv XU, Yuanyang HU, Liwei WANG, Ruzhu WANG,

Frontiers in Energy 2010, Volume 4, Issue 2, Pages 181-184 doi: 10.1007/s11708-009-0065-2

Abstract: calcium chloride with expanded graphite, and calcium chloride with activated carbon, the strongest oxidationcreation and pitting corrosion happened in the solution of calcium chloride with expanded graphite,the weakest oxidation creation happened in the solution of calcium chloride with activated carbon, andpitting corrosion was stronger than oxidation creation in the solution of pure calcium chloride.

Structure creation in earthen construction materials: information from dry soil mixtures

Christopher BECKETT, Charles AUGARDE

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 2, Pages 151-159 doi: 10.1007/s11709-011-0109-7

Abstract: There is increasing interest in the use of earthen construction materials, such as rammed earth, due to their inherent sustainability. These materials have been used by man for thousands of years and some of the earliest examples can be found in China. Features of the structures of these materials arise from the means of production. In particular, in situ earthen construction materials exhibit strong anisotropy due to their layered nature. A more subtle structure effect arises from the way that the earth mixture is deposited. This paper reviews and discusses stratification effects in dry soil mixtures, including some original experimental work, and indicates some links between the features of the dry mixtures and earthen construction materials. Improved understanding of the physical processes in play will allow more accurate specification of these materials in the future, and hence spread their use.

Self-propelled automatic chassis of Lunokhod-1: History of creation in episodes

Mikhail MALENKOV

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 1, Pages 60-86 doi: 10.1007/s11465-016-0370-5

Abstract:

This report reviews the most important episodes in the history of designing the self-propelled automatic chassis of the first mobile extraterrestrial vehicle in the world, Lunokhod-1. The review considers the issues in designing moon rovers, their essential features, and the particular construction properties of their systems, mechanisms, units, and assemblies. It presents the results of exploiting the chassis of Lunokhod-1 and Lunokhod-2. Analysis of the approaches utilized and engineering solutions reveals their value as well as the consequences of certain defects.

Integration of VR with BIM to facilitate real-time creation of bill of quantities during the design phase

Jordan DAVIDSON, John FOWLER, Charalampos PANTAZIS, Massimo SANNINO, Jordan WALKER, Moslem SHEIKHKHOSHKAR, Farzad Pour RAHIMIAN

Frontiers of Engineering Management 2020, Volume 7, Issue 3, Pages 396-403 doi: 10.1007/s42524-019-0039-y

Abstract: As building practices change, procedures that seemed indispensable at one point can be abandoned for others, one example of which is the bill of quantities (B/Q). Research into the extant literature attributes the declining use of B/Qs to a multitude of reasons, such as its complexity, the potentially long time required to produce it, the growth in popularity of non-traditional procurement systems, and the challenge of using the information within the document in a construction schedule. With these issues in mind, building information modeling (BIM) and virtual reality (VR) are combined and proposed as a potential solution that allows inclusion of the client into the design process. Following a literature review and precedent study, an experiment was carried out using this new process to simulate a client’s design decisions on window and interior furnishings. The choices made by the client using VR automatically updated a B/Q schedule built in Revit and allowed them to have a firm understanding of project costs. Besides giving the client more confidence in a pleasing final outcome, the technology also ensured an up-to-date, accurate, and easily understandable B/Q. The proposed method features great potential savings in cost and time and gives the B/Q a newfound importance in future construction processes. The research case presented in this paper is a stepping stone in exploring new opportunities offered by VR and BIM and how they could improve the reliability and accuracy of traditional procurement within construction, specifically within the B/Q document.

Inheritance and Innovation of Engineering Management Informatization

Kai Sun,Ren-huai Liu

Frontiers of Engineering Management 2014, Volume 1, Issue 1, Pages 76-82 doi: 10.15302/J-FEM-2014014

Abstract: In the life-cycle of large projects, the operational phase lasts the longest, costs the most and substantially benefits the project. During the whole phase, energy, material and human resources may cost a lot. Effective control of such costs is one of the main targets of engineering management informatization. How to lower the organization collaboration cost in project management and how to support effective collaboration among different areas, organizations and departments in the ways of technology and management are major goals in engineering management informatization. In the phase of project operation, project owners, partners and customers are the stakeholders of engineering management informatization. Through the case of airport management informatization, inherited and innovation of engineering management informatization will be discussed. It is illustrated that airport informatization is the innovation of business model and technology applications through the analysis and study on cases of airport informatization.
