In this work, we define the notion of an algebraic distance in algebraic cone metric spaces defined by Niknam et al. [A. Niknam, S. Shamsi Gamchi and M. Janfada, Some results on TVS-cone normed spaces and algebraic cone metric spaces, Iranian J. Math. Sci. Infor. 9 (1) (2014), 71--80] and introduce some its elementary properties. Then we prove the existence and uniqueness of fixed point for a B...

Polymer-stabilized ferroelectric liquid crystals (PSFLCs) are made by photopolymerizing 3% reactive mesogenic monomer on a quasi bookshelf texture of a ferroelectric liquid crystal (FLC). We observe the formation of nano-scaled polymer fibrils templated by the two dimensionally ordered host. The polymer fibrils capture the orientation of the host with thin polymer fibrils interweaving the smect...

Article history: Received 29 March 2016 Received in revised form 7 June 2016 Accepted 20 June 2016 Available online 21 June 2016 In this work we demonstrate a fabrication process for three-dimensional (3D) container, which is composed of inverted pyramidal pit (IPP) and a capwith nanosized opening fabricated by combining laser interference lithography and anisotropic wet etching processes. The ...

Only a single linearly dispersing π-band cone, characteristic of monolayer graphene, has so far been observed in Angle Resolved Photoemission (ARPES) experiments on multilayer graphene grown on C-face SiC. A rotational disorder that effectively decouples adjacent layers has been suggested to explain this. However, the coexistence of μm-sized grains of single and multilayer graphene with differe...

In this paper, germanium-based solar cells were designed based on germanium (Ge) materials, and the cross-cone (CC) nanostructures used as absorber layer of cells. The optical path inside was increased by microstructure reflection, thereby increasing absorption efficiency cell. reflectivity, transmittance, electric field magnetic corresponding position device simulated calculated finite differe...

objective: maintaining the health of oral tissues is a major goal in dentistry. however, limitations in dental materials, instruments, procedures and medications prevent achievement of this goal. advances in nanotechnology have paved the way to approach this goal. this study reviews the advances on nanotechnology in dentistry. review of literatures: in this review study, google scholar, pubmed,...

This work proposes a convex optimization-based framework for the trajectory planning and tracking of quadcopters that ensures continuous-time safety guarantees. Using convexity property B-spline curves differential flatness quadcopters, second-order cone program is formulated to generate an optimal nominal respects state input constraints, including position, linear velocity, angle, angular thr...
