This work belongs to the field of hydroacoustics, namely problem digitalbeamforming based on spatial fast Fourier transform (FFT) in a multibeam echo sounder(MLS) with baseband digital signal processing. The applicability FFT-based beamformingwhen using relatively broadband signals is considered. main attention paid MLSwith static beam pattern, at same time, obtained results are also applicable...

This research aims to improve the utilization efficiency of parking facilities in residential areas. The real-time and fixed-time shared spot allocation models based on a time window constraint are proposed, respectively. model adopts dynamic response service mechanism, introducing multi-objective decision weighting method construct weighted evaluation function. Then, 0–1 planning with user opt...

in this paper, by means of fuzzy approaches, an accurate method is introduced for edging of color photographs. the difference between our method with other similar methods is the use of a morphological operation to think or thick the obtained edges. in this proposed method, a 3×3 window is dragged on the photo. for each block, 12 point sets will be defined, each including two non-overlapping po...

A new simple form window with the application of FIR filter design based on the exponential function is proposed in this article. An improved window having a closed simple formula which is symmetric ameliorates ripple ratio in comparison with cosine hyperbolic window. The proposed window has been derived in the same way as Kaiser window, but its advantages have no power series expansion in its ...

A recent study demonstrates involvement of primary motor cortex in task-dependent modulation of rapid feedback responses; cortical neurons resolve locally ambiguous sensory information, producing sophisticated responses to disturbances.

This paper presents a method that combines shadow detection and a 3D box model including shadow simulation, for estimation of size and position of vehicles. We define a similarity measure between a simulated image of a 3D box, including the box shadow, and a captured image that is classified into background/foreground/shadow. The similarity measure is used in an optimization procedure to find t...

We report simulation of nanostructured memristor device using piecewise linear and nonlinear window functions for RRAM and neuromorphic applications. The linear drift model of memristor has been exploited for the simulation purpose with the linear and non-linear window function as the mathematical and scripting basis. The results evidences that the piecewise linear window function can aptly sim...

We consider a linear multistage detector with universal (large system) weighting for large asynchronous code-division multiple-access (CDMA). A convenient choice of the basis of the projection subspace allows a joint projection of all users’ signals and avoids truncation effects due to finite time windowing. Thanks to the joint projection the complexity per bit of the proposed detector scales l...

The Higher-Harmonic Control (HHC) algorithm is re-examined from a rigorous control theory-oriented perspective. A brief review of the history and developments of HHC is given, followed by a careful development of the algorithm. The paper proceeds to perform an analytic convergence and robustness analysis. On-line identification with the adaptive variant of the algorithm is also addressed. A new...
