Steering vector errors and diagonal loading [PDF]

open access: yes, 2004
Diagonal loading is one of the most widely used and effective methods to improve robustness of adaptive beamformers. In this paper, we consider its application to the case of steering vector errors, i.e.

Pore pressures and strains after repeated loading of saturated clay [PDF]

open access: yes, 1974
Repeated and sustained loading tests on undrained samples of normally consolidated lacustrine clay are used to prove the existence of a relationship between pore water pressures and axial strains.The behavior of the clay is studied by investigating the ...

Properties of mass-loading shocks, 2. Magnetohydrodynamics [PDF]

open access: yes, 1992
The one-dimensional magnetohydrodynamics of shocked flows subjected to significant mass loading are considered. Recent observations at comets Giacobini-Zinner and Halley suggest that simple nonreacting MHD is an inappropriate description for active ...

Effects of various coatings and packing materials on persimmon fruit color indexes during quasi-static loading [PDF]

open access: yesمجله پژوهش‌های علوم و صنایع غذایی ایران, 2022
Nowadays, the quality of processed fruits or products is defined by a set of physical and chemical properties. In this study, due to the sensitivity of persimmon fruit to pressure, the parameters affecting the color changes of this fruit after pressure ...

A new low-cost discrete bit loading using greedy power allocation [PDF]

open access: yes, 2009
In this paper we consider a low cost bit loading based on the greedy power allocation (GPA). Compared to the standard GPA, which is optimal in terms of maximising the data throughput, three suboptimal schemes are suggested, which perform GPA on subsets ...

Structural design technology of reusable blast-resistant caverns in hard rock mass

open access: yesYantu gongcheng xuebao, 2019
Chemical explosion in rock mass is an important method to study the seismic coupling effects, but the characteristics of rock near the explosive always change or the propagation path of seismic waves always changes, which will bring bad quality of ...

Suboptimal greedy power allocation schemes for discrete bit loading [PDF]

open access: yes, 2013
In this paper we consider low cost discrete bit loading based on greedy power allocation (GPA) under the constraints of total transmit power budget, target BER, and maximum permissible QAM modulation order.
