    AbstractUtility companies incur financial loss due to transmission losses as well as non technical losses like power theft and billing irregularities. Smart meters with the required functionalities along with an intelligent grid form an Automated Meter Reading (AMR) infrastructure which can improve the distribution efficiency. AMR infrastructure can be expanded by allowing for bi-directional communication between the grid components to form an Advanced Metering Infrastructure (AMI). This helps for the smooth interaction between grid components to load and off-load the distributed energy sources while supporting an efficient Demand Side Management of power. Communication technologies play a vital role in the implementation of smart grid and Wireless Sensor Networks are gaining attraction in this field. Routing protocols with high reliability, low latency and that can co-exist with the established protocols are the need of the hour. Routing Protocol for Low Power Lossy Networks (RPL) fit into this space well. An attempt to build an automated infrastructure using RPL for collecting the metering information, which at a later stage can be easily upgraded to an AMI setup by simply adding the supporting end devices for a much more intelligent smart grid, is carried out in this pape

    There are many methodologies for finding patterns in the client's navigation. For instance, acquaints new calculations with retrieve taxonomy of a solitary web webpage from the snap floods of its clients. They have developed a framework to discover how the time influences the client conduct while surfing a web page. That is, they segment the logs of navigation of the clients in various time intervals; and after that they find what time intervals truly meddle with the client conduct

    In the present work, Nickel Oxide thin films were prepared by spin coating technique. The effects of Ethanolamine and HCl on structural and optical properties of NiO thin films are studied. The structural properties of NiO thin films were examined by X-ray Diffraction (XRD). The amorphous nature of NiO thin films were observed from XRD pattern. FESEM studies of the surface morphology of NiO thin films exhibits smooth and uniform surface with average particle size of 200 nm for Ethanolamine doping sample and 300 nm for HCl doping sample. The functional groups and surface roughness of NiO thin films were investigated by FTIR and 3 D Laser Profilometry. The surface roughness of the prepared samples increases with increasing thickness from 4.49 ÎŒm to 6.81 ÎŒm. The optical characteristics of the samples were determined by UV Visible Spectrophotometer. This results shows that the prepared NiO thin films exhibits high optical transparency

    Approximating Fixed Points of Relatively Nonexpansive Mappings via Thakur Iteration

    The study of symmetry is a major tool in the nonlinear analysis. The symmetricity of distance function in a metric space plays important role in proving the existence of a fixed point for a self mapping. In this work, we approximate a fixed point of noncyclic relatively nonexpansive mappings by using a three-step Thakur iterative scheme in uniformly convex Banach spaces. We also provide a numerical example where the Thakur iterative scheme is faster than some well known iterative schemes such as Picard, Mann, and Ishikawa iteration. Finally, we provide a stronger version of our proposed theorem via von Neumann sequences.This work has been partially funded by the Basque Government through Grant IT1207-19

    Failure to initiate treatment for tuberculosis patients diagnosed in a community survey and at health facilities under a DOTS programme in a district of south India

    Get PDF
    We studied the proportion and fate of tuberculosis patients who were not initiated on treatment (initial defaulters) in Tiruvallur district of Tamilnadu, where DOTS strategy was implemented. These patients were visited to find out the reason for default. Treatment was not initiated in 57 (23.5%) of the 243 sputum positive cases diagnosed in a community survey and 156 (14.9%) of 1049 patients diagnosed in health facility. Men were more likely not to have treatment initiated. The common reasons stated for initial default were unwillingness, symptoms being mild, personal reasons and dissatisfaction. There is an urgent need to improve the patient’s perception of treatment and strengthen the health systems’ capabilities to reduce initial default

    Proximally Compatible Mappings and Common Best Proximity Points

    Get PDF
    The purpose of this paper is to introduce and analyze a new idea of proximally compatible mappings and we extend some results of Jungck via proximally compatible mappings. Furthermore, we obtain common best proximity point theorems for proximally compatible mappings through two different ways of construction of sequences. In addition, we provide an example to support our main result.This work has been partially funded by Basque Government through Grant IT1207-19
