Big data query optimization by using Locality Sensitive Bloom Filter

For faster access of data or in network bloom filter plays an important part in searching technique. It process data in short amount of time and frequently with probabilistic analysis. Bloom Filter also decreases the cost of analyzing data. Various applications are using this technology for accessing and processing the data. Thus by implementing Bloom’s Filter over […]

IGBT-based switching modules for laser applications

This paper presents the design of IGBT-based switching modules for a nitrogen gas laser. First, the CC-topology, which drives the laser, is discussed and simulated. Simple models of the laser tube and the switch are presented. The comparison of the simulation with experimental data shows good accuracy. The results are used to discuss the influence […]

On-Chip Reflectivity-Tunable Single Wavelength Reflector

We propose an on-chip reflectivity-tunable single wavelength reflector, based on a coupling-modulation microring with an integrated reflective element. Reflectivity ranging from 0 to 1 can be obtained by tuning the coupling coefficient. With the reflective element parameters chosen carefully, the operation bandwidth of the reflector can be designed to accommodate the input signal with different […]

Neuro-fuzzy state space controller for drive with elastic joint

This paper presents adaptive control structure applied for electrical drive with elastic coupling between motor and load machine. The main speed controller is based on neuro-fuzzy model. Proposed control structure works using all state variables of the two-mass system. Feedbacks coefficients have been calculated analytically. Information about state variables is given by the Luenberger observer. […]

Soft Quorums: A High Availability Solution for Service Oriented Stream Systems

Large-scale information gathering becomes more and more common with the increasing popularity of smartphones, GPS, social networks, and sensor networks. Services based on this real-time data are the logical next step. Service Oriented Stream Systems (SOSS) have a focus on one-time ad hoc queries as op-posed to continuous queries. High availability is crucial in these services. However, […]

Experimental Investigation on Fiber-Wireless MIMO System With Different LO at W Band

We experimentally demonstrate an optical-wireless transmission system at W band, which can support long-distance wireless transmission and tolerate some frequency difference of the local oscillators (LOs) at the receiver. The generation of millimeter-wave signal is based on the photonic technique by heterodyne mixing of an optical polarization division multiplexing quadrature phase shift keying (PDM-QPSK) signal […]

Competing Magnetic Interactions in Co Doped La0.7Sr0.3MnO3

The crystallographic structural and magnetic properties of polycrystalline La0.7Sr0.3Mn1-xCoxO3 (x =0.4, 0.5, 0.6, 1.0) have been systematically studied in detail by neutron powder diffraction and magnetic measurements.The introduction of Co dopant to the Mn network has decreased the bandwidth (W)and the overlap between the O-2p and the Mn-3d orbitals. Also it in turn weakened the fragile double […]

Cutting the last wires for mobile communications by microwave power transfer

The advancements in microwave power transfer (MPT) over recent decades have enabled wireless power transfer over long distances. The latest breakthroughs in wireless communication – massive MIMO, small cells, and millimeterwave communication – make wireless networks suitable platforms for implementing MPT. This can lead to the elimination of the “last wires” connecting mobile devices to the grid […]
