Real number Laplace Transformation-based identification and its application
2009 International Conference on Mechatronics and Automation, 2009Co-Authors: Satoshi Suzuki, Katsuhisa FurutaAbstract:This paper verifies the proposed identification method for a first-order system including time-delay. This method is based on the Laplace Transformation in real number domain and is able to estimate both coefficients of the first-order system and the time-delay simultaneously. Applying the method to identification of an engine sensor, issues under practical usage were investigated, and the countermeasure was reported.

real number Laplace Transformation based identification for first order system including time delay
Emerging Technologies and Factory Automation, 2008Co-Authors: Satoshi Suzuki, Katsuhisa FurutaAbstract:This paper proposes a simple yet effective identification method for a first-order system including a time-delay. This method is based on the Laplace Transformation in real number domain and is able to estimate both coefficients of the first-order system and the time-delay simultaneously. The accuracy of the identification results was analyzed using simulation. Precise estimation of the present method was confirmed compared to an orthodox on-line estimation technique utilizing a bilinear-model. Furthermore, a guideline for tuning the parameters used in the method is shown.

an alternative method for computing thermal stress in asphalt mixture the Laplace Transformation
Road Materials and Pavement Design, 2017Co-Authors: Augusto Cannone Falchetto, Ki Hoon Moon, Michael P WistubaAbstract:Low-temperature cracking is one of the most severe distresses for asphalt pavement experiencing severely cold weather conditions. Many road authorities recognise thermal stress as a crucial parameter for evaluating the low-temperature performance of asphalt pavement. Thermal stress is conventionally computed with a two-step approach where the relaxation modulus is derived from the experimental creep compliance after which the convolution integral is numerically solved. In this paper, a one-step computation solution based on Laplace Transformation is proposed. Thermal stress and corresponding critical cracking temperature of a set of six mixtures are easily computed and graphically and statistically compared to the values obtained with the traditional approach. It is observed that the use of the Laplace-based method provides reliable and reasonably close results to those obtained with the conventional solution.

comparison of thermal stress calculation hopkins and hamming s algorithm and Laplace Transformation approach
Journal of Materials in Civil Engineering, 2016Co-Authors: Augusto Cannone Falchetto, Ki Hoon MoonAbstract:AbstractLow-temperature cracking is a severe distress for asphalt pavement built in cold regions. When a steep drop in temperature is experienced, thermal stress develops in the different pavement layers and, as a critical temperature value is reached, cracking occurs. Hence, thermal stress represents a relevant parameter for predicting the low-temperature performance of asphalt pavements. Conventionally, thermal stress is calculated by converting the experimental results of creep compliance to a relaxation modulus and then by numerically solving the convolution integral. Hopkins and Hamming’s algorithm is commonly used for this purpose in many research efforts. In this paper, the use of Laplace Transformation is evaluated as an alternative approach since, by using this method, thermal stress and critical temperature can be directly and easily derived without relying on a traditional two-step computation process. The results obtained from Hopkins and Hamming’s solution and from the Laplace Transformation ...

calculation of impedance spectra by Laplace Transformation of voltage transients generated by current step excitation
Journal of Electroanalytical Chemistry, 1994Co-Authors: M Neumannspallart, M EtmanAbstract:Abstract Impedance data over a broad frequency range were obtained by converting the transient voltage response of a passive network to a current-step excitation into the frequency domain using Laplace Transformation. The merits and limitations of the method and the type and quality of the required data are discussed. Examples of impedance plots obtained using this method are given.

A new Laplace Transformation method for dynamic testing of solar collectors
Renewable Energy, 2015Co-Authors: Weiqiang Kong, Bengt Perers, Jianhua Fan, Simon Furbo, Federico BavaAbstract:A new dynamic method for solar collector testing is developed. It is characterized by using the Laplace Transformation technique to solve the differential governing equation. The new method was inspired by the so called New Dynamic Method (NDM) (Amer E. et al (1999) [1]) but totally different. By integration of the Laplace Transformation technique with the Quasi Dynamic Test (QDT) model (Fischer S. et al (2004) [2]), the Laplace – QDT (L-QDT) model is derived. Two experimental methods are then introduced. One is the shielding method which needs to shield and un-shield solar collector continuously during test period. The other is the natural test method which doesn't need any intervention.
