Governance of humanoid robot using master exoskeleton

Abstract: Dexto:Eka: is an adult-size humanoid robot being developed with the aim of achieving tele-presence The paper sheds light on the control of this robot using a Master Exoskeleton which comprises of an Exo-Frame, a Control Column and a Graphical User Interface It further illuminates the processes and algorithms that have been utilized to make an efficient system that would effectively emulate a tele-operator

Long Period Fiber Grating Based Novel Optical Fiber Devices

Abstract: Long Period Gratings (LPGs) in optical fibers have found wide applications as wavelength filters, sensors etc. This paper presents our recent work on superimposed LPG designs which show very interesting transmission characteristics. By appropriate design, these are expected to find applications as wavelength filters, sensors, channel isolation filters and wavelength interrogators. Adiabatic passage of light between twocore modes via an intermediate cladding mode without much excitation of the cladding mode is shown as an interesting application.

Contamination of building roof dust in India

Abstract: The ambient air quality in Raipur city, Chhattisgarh state, India is poor during the winter season due to the lowest wind speed and temperature inversion. The whole buildings in the city are covered by the black fugitive dust. In this work, characterization and sources of contaminants, i.e. carbons, Al, As, Cr, Mn, Fe, Ni, Cu, Zn, Pb, Cd, F−, Cl−, SO4 2−, NO3 −, NH4 +, Na+, K+, Mg2+ and Ca2+, in the building roof dust of Raipur area, central India are described. Significant concentration of black carbon (BC), SO4 2−, Ca2+, Al, Fe and Mn in the dusts was observed, ranging from 8.7 to 21.9, 0.5 to 2.1, 1.8 to 2.9, 2.1 to 4.8, 6.2 to 13.4 and 0.34 to 0.95 % with mean value (p = 0.05) of 14.1 ± 2.6, 1.2 ± 0.3, 2.3 ± 0.2, 3.3 ± 0.4, 9.4 ± 1.2 and 0.64 ± 0.11 %, respectively. The concentration of toxic metals, i.e. As, Cr, Ni, Cu, Zn, Cd and Pb, ranged from 13.8 to 47.3, 57 to 187, 36 to 89, 31 to 177, 208 to 472, 0.11 to 0.53 and 93 to 366 mg kg−1 with mean value (p = 0.05) of 21.5 ± 6.0, 111 ± 22, 59 ± 9, 102 ± 23, 306 ± 48, 0.28 ± 0.08 and 176 ± 48 mg kg−1, respectively. The cluster and factor analysis models were used to apportion sources of elements linked to several anthropogenic activities in the study area. The concentration variations, pollution indices and toxicities of the contaminants are described.

Sustainable benefits of electronic waste recycling in India: a system dynamics analysis

Abstract: Despite the fact that 95% of the electronic waste (e-waste) generated is routed to unorganised sector, India is still struggling to put up an effective e-waste management system. This paper highlights the sustainability link of an efficient and effective e-waste reverse supply chain (RSC) of e-waste in India. A system dynamics (SD) model of circular flow of electronics products from manufacturing stage to recycling stage has been developed using STELLA Software version 9.1.3. Seven scenarios have been simulated using the model to study behaviour of various variables. Study of trends provides very useful insights to facilitate policy decisions for implementation of e-waste RSC in India. This study also recommends various strategies to improve the collection efficiency of the organised sector.
