We propose a new approach to value-directed belief state approximation for POMDPs. The valuedirected model allows one to choose approximation methods for belief state monitoring that have a small impact on decision quality. Using a vector space analysis of the problem, we devise two new search procedures for selecting an approximation scheme that have much better computational properties than e...

In this paper, performance of long term evolution (LTE) over fiber system is investigated by optical frequency multiplication (OFM) method to generate high-order millimeterwave (mm-wave) using a dual-electrode Mach-Zehnder modulator (DE-MZM) in radio over fiber. Here, optical double sideband subcarrier (DSBSC) scheme is adopted to overcome fiber dispersion-induced RF power fading. Experimental ...

Numerical stability of the Levinson algorithm, generalized for Toeplitz-like systems, is studied. Arguments based on the analytic results of an error analysis for floating point arithmetic produce an upper bound on the norm of the residual vector, which grows exponentially with respect to the size of the problem. The base of such an exponential function can be small for diagonally dominant Toep...

The carrier-frequency (CF) and intermediate-frequency (IF) pulse-width modulators (PWMs) based on delay lines are proposed, where baseband signals are conveyed by both positions and pulse widths or densities of the carrier clock. By combining IF-PWM and precorrected CF-PWM, a fully digital transmitter with unit-delay autocalibration is implemented in 180 nm CMOS for high reconfiguration. The pr...

Datasets with a large amount of noisy data are quite common in real-world classification problems. Robustness is an important characteristic of state-of-the-art classifiers that use error minimization techniques, thus requiring a long time to converge. This paper presents ClusWiSARD, a clustering customization of the WiSARD weightless neural network model, applied to credit analysis, a non-triv...

A CMOS transceiver fully compliant with IEEE 802.11a in the unlicensed national information infrastructure (UNII) band (5.15–5.35 GHz) achieves a receiver sensitivity of 5 dBm for 64-QAM (quadrature amplitude modulation) with an error vector magnitude (EVM) of 29.3 dB. A single-sideband mixing technique for local-oscillator signal generation avoids frequency pulling. Realized in 0.18m CMOS and ...

Abstract-A six-port receiver can restore the original modulated signal by calculating the detected envelopes and system parameters of the six-port circuit. The system parameters have been determined at each frequency in advance. The six-port receiver has an advantage in the point that the user can select the frequency arbitrarily, but there is a problem of nonlinear distortion in the detector b...

Quantum computation has been proposed to generate consciousness. The terms atman field and consciousness vector have also been used to describe the properties of consciousness. It has also been proposed that the human activities should lead to increase in the magnitude of the consciousness vector of the universe. The universe is increasingly being seen as one system and the earth is a constitue...

In this article is proposed the Direct Torque Control (DTC) with Space Vector Modulation (SVM) based on Self-Tuning PI-Type Fuzzy (STPIF) controller. This controller determines dynamically the load angle between stator and rotor flux vectors and in consequence the electromagnetic torque necessary to supply the motor load. The rule base for STPIF controller is defined in function of the error an...
