Heterogeneity in topographic control on velocities of Western Himalayan glaciers

Abstract: Studies of the seasonal and annual patterns of glacier velocities improve our understanding of the ice volume, topography, responses to climate change, and surge events of glaciers. Such studies are especially relevant and equally rare for the Himalayan glaciers, which supply many rivers that sustain some of the most heavily populated mountainous regions in the world. In particular, the control of the hypsometric distribution of geomorphometric parameters, such as slope, aspect, and curvature, on the dynamics of Himalayan glaciers have never been studied so far, at the river basin scale. Here, we present the degree to which topographic and hypsometric parameters affect the seasonal and annual average flow velocities of 112 glaciers in the Baspa River basin in the Western Indian Himalaya by analysing Global Land Ice Velocity Extraction from Landsat 8 (GoLIVE) datasets for the years 2013–2017. We observe, (i) significant heterogeneity in topographic controls on the velocities of these glaciers, (ii) elevation and the seasons play important roles in regulating the degree to which morphometric parameters (slope, aspect, and curvature) affect these velocities, (iii) a possible polythermal regime promoting both sliding and deformational forms of motion in a majority of these glaciers, and (iv) a detailed analysis of complex topographic controls within various elevation zones using a novel hypso-morphometric approach. These findings can help us to better model the dynamics of Himalayan glaciers and their responses to the future climatic scenarios. The inferences also suggest the need to incorporate dynamic topography in glacio-hydrological models in the wake of constant glacial evolutions.

Applicability of Industrial IoT in Diversified Sectors: Evolution, Applications and Challenges

Abstract: Internet of Things (IoT) is defined as an interconnection among several devices which share data and all other relevant information across the network using unique identifiers without the involvement of humans. Any physical device can be easily operatable by using sensing devices, which reduces human workforce. The applications of IoT have been used in each and every field. With its ease of use of applicability in every sector, it is nowadays used in Industrial Internet of Things (IIoTs). In this paper, we present an overview of different emerging applications of IoT such as blockchain applications in Industry 4.0 and IIoT settings. As security is considered main aspect in any model; therefore, security metrics have been highlighted along with IoT-based architecture. Later section of paper describes the evolution of IIoT, revolution in industrial sector, collaboration of Industry 4.0 and IIoT, industrial automation, cybersecurity and data analytics, blockchain enrolled with IIoT, applications in public domain, etc.
