Internet of Things (Iot) for Smart Cities- The Future Technology Revolution
Today the world is becoming connected. The number of devices that are connected are increasing day by day. Many studies reveal that about 50 billion devices would be connected by 2020 indicating that Internet of things have a very big role to play in the future to come. The applications of IoT are immense which include Energy, Healthcare, and Agriculture to name a few. IoT is an emerging technology that works with the integration of many other present day technologies. There are many threats to the environment today among them urbanization is one. The growing needs of the uraban population across the world are posing a serious threat to the environment. We need to act fast and meet these needs by developing technologies that cater the world problems. One such solution is to develop a smart world. The most important application of IoT is smart cities. Smart city represents one of the most promising, important and difficult Internet of Things (IoT) applications. In the last few years, the smart city concept has played an important role in both scholastic and industry fields, with the advancement and operation of various middleware platforms and IoT-based infrastructures. This paper talks about the role of IoT in developing smart cities for a smarter world
Quenching of spectroscopic factors for proton removal in oxygen isotopes
We present microscopic coupled-cluster calculations of the spectroscopic
factors for proton removal from the closed-shell oxygen isotopes
O with the chiral nucleon-nucleon interaction at
next-to-next-to-next-to-leading order. We include coupling-to-continuum degrees
of freedom by using a Hartree-Fock basis built from a Woods-Saxon
single-particle basis. This basis treats bound and continuum states on an equal
footing. We find a significant quenching of spectroscopic factors in the
neutron-rich oxygen isotopes, pointing to enhanced many-body correlations
induced by strong coupling to the scattering continuum above the neutron
emission thresholds.Comment: 3 figure
Pattern Formation on Trees
Networks having the geometry and the connectivity of trees are considered as
the spatial support of spatiotemporal dynamical processes. A tree is
characterized by two parameters: its ramification and its depth. The local
dynamics at the nodes of a tree is described by a nonlinear map, given rise to
a coupled map lattice system. The coupling is expressed by a matrix whose
eigenvectors constitute a basis on which spatial patterns on trees can be
expressed by linear combination. The spectrum of eigenvalues of the coupling
matrix exhibit a nonuniform distribution which manifest itself in the
bifurcation structure of the spatially synchronized modes. These models may
describe reaction-diffusion processes and several other phenomena occurring on
heterogeneous media with hierarchical structure.Comment: Submitted to Phys. Rev. E, 15 pages, 9 fig

The Detection and Location of Hydrido Ligands in High Nuclearity Osmium and Ruthenium Carbonyl Clusters: A Critical Survey
Hydrido carbonyl clusters represent powerful molecular models for the co-adsorption of carbon monoxide and hydrogen on metal surfaces, a key step in several catalytic processes. Over the past two decades a considerable number of such species have been reported in the literature. In this paper, the structural chemistry of high nuclearity osmium and ruthenium hydrido carbonyl clusters is critically reviewed. Particular emphasis is placed on the limits of the various indirect methods of hydride location in clusters, and an alternative interpretation of the results of spectroscopic studies performed for samples of some Ru and Os clusters in solution is given
Functionalized Polyvinylidene Fluoride Electrospun Nanofibers and Applications
Electrospun polymeric nanofibers with flexible three-dimensional porous structures and high surface-to-volume ratio are potential resources for several novel applications in the fields of micro- and nanoscale filtration, water desalination, drug delivery, life sciences, catalysis, and energy harvesters. Functionalized polymeric fibers with enhanced molecular orientation, surface textural morphologies, and piezo-, pyro-, and ferroelectric properties are of technical and commercial interest around the world. Several emerging technologies including electrical polarization, vacuum plasma treatment, corona discharge, surface fluorination, and chemical treatments to functionalize the polyvinylidene fluoride nanofibers are discussed as potential applications of electroactive materials
Phase ordering induced by defects in chaotic bistable media
The phase ordering dynamics of coupled chaotic bistable maps on lattices with
defects is investigated. The statistical properties of the system are
characterized by means of the average normalized size of spatial domains of
equivalent spin variables that define the phases. It is found that spatial
defects can induce the formation of domains in bistable spatiotemporal systems.
The minimum distance between defects acts as parameter for a transition from a
homogeneous state to a heterogeneous regime where two phases coexist The
critical exponent of this transition also exhibits a transition when the
coupling is increased, indicating the presence of a new class of domain where
both phases coexist forming a chessboard pattern.Comment: 3 pages, 3 figures, Accepted in European Physics Journa
