Blind adaptive constrained reduced-rank parameter estimation based on constant modulus design for CDMA interference suppression [PDF]

open access: yesIEEE Transactions on Signal Processing, 2008
This paper proposes a multistage decomposition for blind adaptive parameter estimation in the Krylov subspace with the code-constrained constant modulus (CCM) design criterion.

Robust adaptive beamforming algorithms using the constrained constant modulus criterion

open access: yesIET Signal Processing, 2014
The authors present a robust adaptive beamforming algorithm based on the worst‐case (WC) criterion and the constrained constant modulus (CCM) approach, which exploits the constant modulus property of the desired signal. Similar to the existing worst‐case beamformer with the minimum variance design, the problem can be reformulated as a second‐order cone

Determination of Mechanical Properties of Soils Based on CPTU Data

open access: yesArchitecture, Civil Engineering, Environment, 2023
The study aimed to interpret the results of cone penetration tests with pore pressure measurement (CPTU). Tests were performed on a section of the designed road about 200 m long.

Mutual information‐based constant‐modulus waveform design for multiple‐input‐multiple‐output radar in spectrally crowded environment

open access: yesIET Radar, Sonar & Navigation, 2023
This study considers designing constant‐modulus waveforms for multiple‐input‐multiple‐output radar in spectrally crowded environment. The mutual information is used as the waveform design metric.

Loop expansion in Yang-Mills thermodynamics [PDF]

open access: yes, 2006
We argue that a selfconsistent spatial coarse-graining, which involves interacting (anti)calorons of unit topological charge modulus, implies that real-time loop expansions of thermodynamical quantities in the deconfining phase of SU(2) and SU(3) Yang ...

Inequalities for the maximum modulus of univariate constrained polynomials

open access: yesFilomat, 2021
This paper deals with the problem of finding some upper bound estimates for the maximum modulus of a univariate complex polynomial on a disk under certain constraints on the zeros and on the functions involved. A variety of interesting results follow as special cases from our general results.

The Use of CPTU and DMT Methods to Determine Soil Deformation Moduli—Perspectives and Limitations

open access: yesStudia Geotechnica et Mechanica, 2023
The article presents the concept of determining constrained modulus—M0, initial shear modulus—G0, Young modulus—E, and rigidity index—IR on the basis of parameters from static penetration tests CPTU (Piezocone Penetration Testing), SCPTU (Seismic ...

Mechanical properties of connected carbon nanorings via molecular dynamics simulation [PDF]

open access: yes, 2005
Stable, carbon nanotori can be constructed from nanotubes. In theory, such rings could be used to fabricate networks that are extremely flexible and offer a high strength-to-density ratio.
