Abstract Ambient cured epoxy adhesive is widely used for bonding fibre reinforced polymer (FRP) plates to metallic structures. The present paper examines a typical strengthening investigate the effect of thermo-viscoelasticity. response was determined using series tests multi-frequency scanning mode dynamic mechanical analyser (DMA). thermo-mechanical properties were then characterised time–tem...

Suggested running title|Statistical Analysis of TLS-Based Prony. Subtitle|We present an analysis of the statistics for the TLS-Prony method by deriving the covariance matrix of the estimated parameters. We verify the theoretical results using Monte-Carlo simulations and compare them to their Cram er-Rao bounds. Abstact We present an analysis of parameter variance statistics for the TLS-Prony me...

We investigate the modified Prony algorithm of Osborne and Smyth (1991, 1993) applied to the estimation of the frequency of oscillation of a sinusoidal signal with added white noise, and compare it with the algorithms usually associated with the names of Prony and Pisarenko. We show that the Pisarenko algorithm returns O(N− 1 2 ) consistent estimates, and that the modified Prony algorithm retur...

Systems of Prony type appear in various signal reconstruction problems such as finite rate of innovation, superresolution and Fourier inversion of piecewise smooth functions. We propose a novel approach for solving Prony-type systems, which requires sampling the signal at arithmetic progressions. By keeping the number of equations small and fixed, we demonstrate that such “decimation” can lead ...

In this paper, signals measured by phasor measurement units (PMUs) are used to monitor power system small signal stability. In the proposed method, proper signals selected based on the modes observability and Prony analysis is employed to extract signal damping information (amplitude and frequency of participated modes) in real-time. The proposed method is simulated using a test signal in ideal...

Vortex induced vibrations (VIV) of long flexible risers subjected to ocean currents exhibit a strongly nonlinear phenomenon. Although significant efforts have been done for the frequency or time-frequency analysis of this complicated phenomenon, an effective method is still lacking. The objective of this paper is to provide a new method — a Prony-based method — for analyzing the time-varying fr...

The modeling and analysis of electric power disturbances affecting power quality has emerged as an important field in the changing electric power industry. These disturbances differ in characteristics, and their occurrence can be attributed to various reasons. Tools capable of classifying these disturbances have been investigated and many are under development. This paper illustrates the harmon...

We consider polynomial systems of Prony type, appearing in many areas of mathematics. Their robust numerical solution is considered to be difficult, especially in “near-colliding” situations. We consider a case when the structure of the system is a-priori fixed. We transform the nonlinear part of the Prony system into a Hankel-type polynomial system. Combining this representation with a recentl...

The dura mater is the outermost and most substantial meningial layer of central nervous system (CNS) tissue that acts as a protective membrane for the brain and spinal cord. In animal models of traumatic brain injury and spinal cord injury, mechanical insults are often delivered directly to the dura to injure the underlying tissue. As such, including a description of the mechanical properties o...
