| 1 | Role based access control design using Triadic concept analysis显示文摘Role based access control is one of the widely used access control models.There are investigations in the literature that use knowledge representation mechanisms such as formal concept analysis(FCA),description logics,and Ontology for representing access control mechanism.However,while using FCA,investigations reported in the literature so far work on the logic that transforms the three dimensional access control matrix into dyadic formal contexts.This transformation is mainly to derive the formal concepts,lattice structure and implications to represent role hierarchy and constraints of RBAC.In this work,we propose a methodology that models RBAC using triadic FCA without transforming the triadic access control matrix into dyadic formal contexts.Our discussion is on two lines of inquiry.We present how triadic FCA can provide a suitable representation of RBAC policy and we demonstrate how this representation follows role hierarchy and constraints of RBAC on sample healthcare network available in the literature. | Ch.Aswani Kumar S.Chandra Mouliswaran LI Jin-hai C.Chandrasekar | 2016 | Journal of Central South University2016，23，12： | 7 |
| 2 | Multifunctional core-shell-like nanoarchitectures for hybrid supercapacitors with high capacity and long-term cycling durability显示文摘Transition metal oxide/hydroxide with multif unctional hierarchical nano structures has attracted widespread attention in supercapacitors(SCs)because of their large accessible surface area,high electrochemical activity and superior redox chemistry.Herein,core-shell-like copper(Cu)hydroxide nano tube arrays grafted nickel aluminum layered double hydroxide n anosheets were facilely synthesized on porous Cu foam(CH NTAs@NiAI LDH NSs)for use as an efficient battery-type electrode in hybrid SCs.With the synergistic effects of NiAl LDH NSs on well-adhered CH NTAs/CF,the core-shell-like composite(prepared for 24 h)delivered a maximum areal capacity of 334.3 pAh/cm2 at a current density of 3 mA/cm2 in 2 M KOH electrolyte,which is comparatively higher than other samples synthesized at different growth times.Moreover,the core-shell-like CH NTAs@NiAI LDH NSs-24 demonstrated an outstanding cycling stability of 134.3%after 10,000 cycles.Utilizing high capacity and stability of CH NTAs@NiAI LDH NSs-24,a pouch-type hybrid SC was further assembled with core-shell-like composite as a positive electrode and reduced graphene oxide as a negative electrode with a filter paper as a separator in aqueous alkaline electrolyte.The hybrid SC showed a high areal capacity of 250 pAh/cm2 at 2 mA/cm2 with maximum areal energy and power densities of 181.9 pWh/cm2 and 24,991.5 pW/cm2,respectively.Successfully harvest!ng the solar energy via solar cell panel and subsequently delivering the stored en ergy to switching and proximity applicati ons also dem on strated the real-time applicability of our hybrid SCs. | S.Chandra Sekhar Goli Nagaraju Bhimanaboina Ramulu Sk.Khaja Hussain D.Narsimulu Jae Su Yu | 2019 | Nano Research2019，12，10： | 2 |

| 4 | Electroosmotic oscillatory flow of micropolar fluid in microchannels:application to dynamics of blood flow in microfluidic devices显示文摘The electroosmotic flow of a micropolar fluid in a microchannel bounded by two parallel porous plates undergoing periodic vibration is studied. The equations for conservation of linear and angular momentums and Gauss' s law of charge distribution are solved within the framework of the Debye-H¨uckel approximation. The fluid velocity and microrotation are assumed to depend linearly on the Reynolds number. The study shows that the amplitude of microrotation is highly sensitive to the changes in the magnitude of the suction velocity and the width of the microchannel. An increase in the micropolar parameter gives rise to a decrease in the amplitude of microrotation. Numerical estimates reveal that the microrotation of the suspended microelements in blood also plays an important role in controlling the electro-osmotically actuated flow dynamics in microbio-fluidic devices. | J.C.MISRA S.CHANDRA G.C.SHIT P.K.KUNDU | 2014 | Applied Mathematics and Mechanics(English Edition)2014，35，6： | 2 |
| 5 | Nanostructural Features and Optical Performance of RF Magnetron Sputtered ZnO Thin Films显示文摘Zinc oxide (ZnO) thin films were grown on silicon substrate by RF (radio frequency) magnetron sputtering.Surface topography of these films exhibited a nanostructured granular appearance with the size of individual grains between 50 to 100 nm.Corresponding cross-sectional electron micrographs revealed columnar grains in the form of aggregated nanorods/wires with length of about 500 nm,similar to the thickness of these thin films of ZnO nucleated and grown vertically on the silicon substrate.High resolution lattice scale imaging using high resolution transmission electron microscope (HRTEM) elucidated the single crystalline 1010 planes of hexagonal-ZnO constituting the columnar grains with the individual nanorod diameter between 3 and 4 nm.The photoluminescence measurements showed the prominent emission peak at around 460 nm for the blue band,normally attributed to intrinsic defects in particular interstitial zinc (Zn).These films were further characterized by X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FTIR),Raman spectroscopy and electron paramagnetic resonance (EPR) to evaluate various aspects on preferred growth orientations,band structures and vibrational modes originated in such fascinating nano-grained thin films of ZnO.The present investigations inferred that these films are advantageous in various potential applications for fabricating nano-scaled devices. | A.K.Srivastava Praveen M.Arora S.K.Gupta B.R.Chakraborty S.Chandra S.Toyoda H.Bahadur | 2010 | Journal of Materials Science & Technology2010，26，11： | 1 |

| 8 | In situ deposited cobalt-magnesium selenates as an advanced electrode for electrochemical energy storage显示文摘Currently,bimetallic selenates have attracted much attention as a prominent electrode composite material for supercapacitors owing to their higher redox chemistry and superior electrical conductivity.Herein,we synthesized cobalt-magnesium selenates (CoSeO3-Mg Se O4,CMS) via a facile hydrothermal process,followed by selenization.At first,cobalt-magnesium oxide (Co2.32Mg0.68O4,CMO) was in situ prepared by a one-pot hydrothermal method.An investigation on the morphological change was performed by synthesizing the same CMO samples at different growth times by keeping the temperature constant.The CMO electrode designed for 8 h of growth time (CMO-8 h)with an attractive morphology showed a higher areal capacity of 101.7μAh cm-2(at 3 m A cm-2) than the other CMO electrodes prepared for 6 and 10 h.Further exalted performance was achieved by the selenization of the CMO-8 h sample to form the CMS material.At 3 m A cm-2,the resulted CMS exhibited nearly three times higher capacity,i.e.,385.4μAh cm-2,than the CMO-8 h electrode.Additionally,an asymmetric cell fabricated with CMS as a positive electrode also revealed good energy storage performance.Within the applied voltage between 0 and 1.5 V,the asymmetric cell demonstrated maximum energy density of 0.159 m Wh cm-2(18.6 Wh kg-1) and maximum power density of 18.47 m W cm-2(1938 W kg-1),respectively.Thus,novel magnesium-based metal selenates can act as an efficient electrode for energy storage. | Manchi Nagaraju S.Chandra Sekhar Bhimanaboina Ramulu Shaik Junied Arbaz Jae Su Yu | 2022 | Journal of Magnesium and Alloys2022，10，12： | 0 |
