effects of different friction stir welding conditions on the microstructure and mechanical properties of copper plates

引用

International Journal of Minerals,Metallurgy and Materials 2016年第7期23卷 799-809页

作者： Ali Alavi nia Ali Shirazi Department of Mechanical engineering Bu-Ali Sina University

Friction stir welding is a new and innovative welding method used to fuse materials. In this welding method, the heat generated by friction and plastic flow causes significant changes in the microstructure of the material, which leads to local changes in the mechanical properties of the weld. In this study, the effects of various welding parameters such as the rotational and traverse speeds of the tool on the microstructural and mechanical properties of copper plates were investigated; additionally, Charpy tests were performed on copper plates for the first time. Also, the effect of the number of welding passes on the aforementioned properties has not been investigated in previous studies. the results indicated that better welds with superior properties are produced when less heat is transferred to the workpiece during the welding process. It was also found that although the properties of the stir zone improved with an increasing number of weld passes, the properties of its weakest zone, the heat-affected zone, deteriorated.

Review of Sodic Soil Reclamation with a Snapshot of Current Research Activity

引用

Chinese Geographical Science 2022年第6期32卷 1099-1109页

作者： TÓth Tibor Institute for Soil Sciences Centre for Agricultural ResearchBudapest 1022Hungary

For centuries, reclamation of sodic soils has been an essential part of cropping practices in several parts of the world. Parallel to increasing population, the need for new cropland constantly re-evaluates land suitability concepts. therefore, the importance of sodic soils as potential croplands is increasing worldwide. Although theoretically farmers can choose from a wide variety of reclamation options, according to profitability, business plans, and human and financial resources, in practice, few reclamation methods are applied at large scale. this article touches on the early history, 20th Century intensive research, and current trends of sodic soil reclamation. New approaches such as leaching, chemical amendments, addition of organic material, and biological and microbial improvements are discussed, and also brand-new approaches are reviewed. the early history is reviewed using historical books, the achievements of the last hundred years using basic technical literature, mostly books, and the current approaches of our time with fresh publications, mostly papers and two very recent conferences published in english.

Transparent conductive oxide-gated silicon microring with extreme resonance wavelength tunability

引用

Photonics Research 2019年第4期7卷 473-477页

作者： eRWeN LI BeHZAD ASHRAFI nia BOKUN ZHOU ALAN x.WANG School of electrical engineering and Computer Science Oregon State University

Transparent conductive oxides have attracted escalating research interest for integrated photonic devices and metasurfaces due to the extremely large electro-optic modulation of the refractive index by the free-carrier-induced plasma dispersion effect. In this paper, we have designed and fabricated a silicon microring resonator using an indium-tin oxide gate as the electric-tuning electrode. It achieved an ultralarge resonance wavelength tunability of 271 pm/V, which is obtained through the reduced width of the ring waveguide and a high-dielectric-constant Hf O2 insulator. We demonstrated a broad resonance wavelength tuning range of over 2 nm with an ultrafast response time of less than 12 ns and near-zero static power consumption, which outperforms traditional thermal tuning.

An insight into the mechanical behavior of binary granular soils

引用

Particuology 2015年第4期13卷 82-89页

作者： F.Vahidi-nia A.Lashkari S.M.Binesh Department of Civil and environmental engineering Shiraz University of Technology

this paper investigates the participation of the fines fraction in the load-carrying structure of binary mixtures of granular soils. For this purpose, various fractions of two fine sands were added to two coarse sands with the same particle size distribution, but different particle shape characteristics. Based on the results of 144 direct shear tests, it was found that fines participation in the load-bearing structure increases with fines content. At the same fines content, the participation of the fines in the load-carrying structure of loose mixtures is greater than in samples that were initially compacted. In addition, it was observed that fines participation rises with the increase in the average size of the fines fraction.

Information schema constructs for defining warehouse databases of genotypes and phenotypes of system manifestation features

引用

Frontiers of Information Technology & electronic engineering 2016年第9期17卷 862-884页

作者： Shahab POURTALeBI Imre HORVáth Faculty of Industrial Design engineering Delft University of Technology

Our long-term objective is to develop a software toolbox for pre-embodiment design of complex and heterogeneous systems, such as cyber-physical systems. the novelty of this toolbox is that it uses system manifestation features(SMFs) for transdisciplinary modeling of these systems. the main challenges of implementation of the toolbox are functional design- and language-independent computational realization of the warehouses, and systematic development and management of the various evolving implements of SMFs(genotypes, phenotypes, and instances). therefore, an information schema construct(ISC) based approach is proposed to create the schemata of the associated warehouse databases and the above-mentioned SMF implements. ISCs logically arrange the data contents of SMFs in a set of relational tables of varying semantics. In this article we present the ISCs necessary for creation of genotypes and phenotypes. they increase the efficiency of the database development process and make the data relationships transparent. Our follow-up research focuses on the elaboration of the SMF instances based system modeling methodology.
