The unprecedented interest in big data has paved way for augmented technologies. One of the major usefulness of big data is found in the field of healthcare analytics. The healthcare data come from varied sources. Specifically EHR data provide a comprehensive view of patient's health. People are paying more attention to their health and want the best possible healthcare especially with new technologies...
With the global demand for renewable energy sources, there is a race in the scientific community to build a highly efficient solar cell. Nanostructured solar cells are a class of photovoltaic devices which is a strong candidate for high efficiency energy generation. Hot carrier solar cells are a kind of nanostructured solar cells, for offering high power conversion efficiency, compared with the conventional...
In the past two decades, due to the advancement in mobile, computing, internet and electronics technology the young generation has turned smart along with the smart cities and villages. People are adapting the globalized changes and these changes are not part of everyone's life. The number of Facebook users fall or rise in every three months. Due to excessive usage of the above mention technology...
3D printing is future of manufacturing technology which creates 3D object using 3D digital model. 3D printed components are very useful in design prototyping as well as manufacturing commercial products. The present article reviews the 3D printing process and our development of a new type of scanner for 3D printing system which achieves faster scanning in a compact space. It consists of serial XY...
An important issue associated with the stability of multi-area power systems is the low damping of electromechanical modes of oscillation. The local modes of oscillations are damped out using local PSS controllers, whereas separate controllers are required for the damping of inter-area oscillation as they require remote measurements as the feedback signal of the controller. This paper investigates...
In this paper, our work aims in fair queuing with priority to consider scheduling of various requests received at the RSU; an important issue for desired data access in vehicular ad-hoc networks. As thousands of requests may arrive at the data center, so scheduling these requests in a proper and efficient way is a challenge. Many scheduling algorithms have been proposed in the literature. In this...
This paper describes a technique for the detection of type of internal fault in an indirect symmetrical phase shift transformer (ISPST). An application of Pattern Recognition Network (PRN) is proposed as a core classifier to identify the type of internal fault. Four type of internal faults (turn-to-turn (TT), line-to-ground (LG), two line-to-ground (LLG), and three line-to-ground (LLLG)) have been...
This paper proposes a new set of moments based on Bateman polynomial which is orthogonal in nature. The translation and scale invariant of Bateman moment has also derived using the linear combination of invariants of geometric moments. Bateman moment takes less order of moment to reconstruct an image. The results have shown that the proposed moment works better than Legendre moment.
The main contribution of this paper is a scheme for optimal phase measurement unit (PMU) placement based on superset & depth of unobservability concept. PMU placement is done in various phases by ensuring that the set of the placed PMUs in the next phase will be a superset of the previous phase. After getting optimum resultant locations of PMUs, the measurements received from the placed PMUs are...

A scheme to achieve impedance matching at three arbitrary frequencies is presented. The proposed matching network is cascade of a dual-band matching network and a novel dual-to-tri-band transformer. Analysis of the proposed network provides closed form design equations that enable physically realizable solution owing to the presence of a free design variable. The presented theory is demonstrated through...

Data center technologies include generators, uninterruptible power supplies, HVAC systems, liquid chiller loops, and all...
This paper focuses on enhancement of lifetime in an event driven wireless sensor network (WSN). The network lifetime is enhanced by optimal deployment of sensor nodes in a given region as premature shortening of life takes place leading to uneven consumption of energy. In the proposed scheme, the senor nodes are linearly deployed over the sub-regions and the inter-node distance between the sensor...
Moment invariants of 3D point distributions may be computed that are ST(scale and translation) invariant, in the same way as 2D moment invariants. Hahn moment is a discrete orthogonal moment which can be a useful set of image feature descriptor. Their higher order moments have better image representation power as compared to legendre and Zernike moments. Hahn moments can be utilized to adaptively...
