3Deposition of atmospheric pollutant and their chemical characterization in snow pit profile at Dokriani Glacier,Central Himalaya显示文摘The uncertainty in assessing the numerous atmospheric pollutants transported via wind from arid and semi-arid regions is affecting the glacial ecosystem. In our study area due to the complexity of the system, a prominent seasonal difference noticed among major ions(Ca^(2+), Mg^(2+), SO_4^(2-), and NO_3^-). There is a need for understanding the ions cycling as a whole and the directionality of the feedback loops in the system. Therefore, we provide an appraisal of our current hypothesis for seasonal difference in major ion concentration from snow samples for two corresponding years(2013 and 2015) at Dokriani Glacier. A systematic study of chemical compositionsin the shallow snow pit from Dokriani Glacier was undertaken for the pre-monsoon season to understand the cycling of major ions from atmosphere to solute acquisition process. The intimating connections of ions cycling in snow and its temporal behavior was observed and analyzed through various statistical tests. Among major ions, the SO_4^(2-)has the highest concentration among anions on an average considered as 14.21% in 2013 and 29.46% in 2015. On the other side Ca^(2+) is the dominant cation contributing 28.22% in 2013 and 15.3% in 2015 on average. The average ratio of Na+/Cl-was higher in 2013 whereas lower in 2015. The backward trajectory analysis suggests the possible sources of the ions transported from Central Asia through the Western Disturbance(WD) as a prominent source of winter precipitation mainly in the Central Himalaya. Ionicconcentration of Ca^(2+) in cations was highly dominated while in anion SO_4^(2-)played the major role. Factor analysis and correlation matrix suggested that, the precipitation chemistry is mostly influenced by anthropogenic, crustal, and sea salt sources over the studied region. The elemental cycling through ocean, atmosphere and biosphere opens up new ways to understand the geochemical processes operating at the glacierized catchments of the Himalaya. Moreover, increasing the field-based studies in the coming decades would also have the certain advantage in overcoming the conceptual and computational geochemical modelling difficulties.Shipika SUNDRIYAL Tanuj SHUKLA Lekhendra TRIPATHEE Dwarika Prashad DOBHAL Sameer Kumar TIWARI Uday BHAN 2018Journal of Mountain Science2018,15,10:2
4激光表面熔化对SiC和MoS2颗粒增强Al-4.5Cu复合材料表面完整性的影响(英文)显示文摘以Al-4.5Cu合金为基体,用搅拌铸造法制备两种复合材料。一种是用10%SiC(质量分数)和2%MoS2(质量分数)进行增强,另一种是用10%SiC(质量分数)和4%MoS2(质量分数)进行增强。为了研究激光表面熔化(LSM)对材料表面性能的影响,采用CO2激光束对材料表面进行重熔。研究激光熔化表面的形貌、显微硬度、耐蚀性和耐磨性。将LSM后的整体表面完整性与铸态表面进行比较。结果表明,LSM能提高每种情况下表面的显微硬度和耐磨性。激光熔化表面孔隙率低,耐蚀性高。因此,LSM可以方便地应用于提高铝基复合材料的表面完整性。然而,在本研究中存在一个最佳的激光比能以获得最佳的表面完整性,约为38 J/m^2。Praveen Kumar BANNARAVURI Anil Kumar BIRRU Uday Shanker DIXIT 2020Transactions of Nonferrous Metals Society of China2020,30,2:2

14IN2CLOUD: A novel concept for collaborative management of big railway data显示文摘In the EU Horizon 2020 Shift2Rail MultiAnnual Action Plan, the challenge of railway maintenance is generating knowledge from data and/or information. Therefore, we promote a novel concept called'IN2CLOUD,' which comprises three sub-concepts, to address this challenge: 1) A hybrid cloud, 2) an intelligent cloud with hybrid cloud learning, and 3) collaborative management using asset-related data acquired from the intelligent hybrid cloud. The concept is developed under the assumption that organizations want/need to learn from each other(including domain knowledge and experience)but do not want to share their raw data or information.IN2CLOUD will help the movement of railway industry systems from 'local' to 'global' optimization in a collaborative way. The development of cutting-edge intelligent hybrid cloud-based solutions, including information technology(IT) solutions and related methodologies, will enhance business security, economic sustainability, and decision support in the field of intelligent asset management of railway assets.Jing LIN Uday KUMAR 2017Frontiers of Engineering Management2017,4,4:1
