Compressive Sensing (CS) can reduce the number of data transmissions and balance the traffic load throughout networks. The sensors nodes are organized into clusters. In this paper we propose a clustering method where in the transmission range of the cluster head (CH) is the area of a cluster. Thus to avoid coverage hole problem. Within a cluster, node transmits data to the CH in a round robin f...
The refractive index sensing characteristics of the side-polished photonic crystal fiber (PCF) surface plasmon resonance (SPR) sensor are detailed investigated in this paper. We used the finite element method (FEM) to study the influences of the side-polished depth, air hole size, lattice constant, and the refractive index (RI) of the PCF material on sensing performance. The simulation results ...
This paper presents a force-visually-observable silicone retractor, which is an extension of a previously developed system that had the same functions of retracting, suction, and force sensing. These features provide not only high usability by reducing the number of tool changes, but also a safe choice of retracting by visualized force information. Suction is achieved by attaching the retractor...
Carbon nanotube transistors have outstanding potential for electronic detection of biomolecules in solution. The physical mechanism underlying sensing however remains controversial, which hampers full exploitation of these promising nanosensors. Previously suggested mechanisms are electrostatic gating, changes in gate coupling, carrier mobility changes, and Schottky barrier effects. We argue th...
Novel magnetic field sensor based on magnetic fluids infiltrated dual-core Photonic Crystal Fibers (PCFs) is proposed in this paper. Inside the cross-section of the designed PCFs, the two fiber cores filled with magnetic fluids (Fe3O4) are separated by an air hole, and then form two independent waveguides with mode coupling. The mode coupling under different magnetic field strength is investiga...
Lateral surface etching of two-dimensional (2D) nanosheets results in holey 2D nanosheets that have abundant edge atoms. Recent reports on holey graphene showed that holey 2D nanosheets can outperform their intact counterparts in many potential applications such as energy storage, catalysis, sensing, transistors, and molecular transport/separation. From both fundamental and application perspect...
Present sensors are inbuilt with sensing capabilities, battery, mobilization and storage capability, for better monitoring of targets and storage of information regarding targets. The sensors can be static or dynamic, depending upon their application. Since the dynamic sensors are costlier, hence are used for supreme purpose. Here we suggest an algorithm for distributed sensor network consistin...
