Nondestructive Survey of a Historical Wooden Construction Using Thermography and Ambient Vibration Measurements |
|
Carlos Humberto Cuadra, Nobuhiro Shimoi(Akita Prefectural University, Japan) |
| Structural evaluation using noninvasive procedures that permit material properties and architectural characteristics to remain intact are used on an old farmhouse which is a local architecture heritage.
Ambient vibration measurements were taken to estimate vibration properties of the structure. Then, infrared thermography was used to detect metallic elements inside the structure since location of these elements can be important to construct accurate analytical structural models. Applicability of these noninvasive procedures was verified for evaluation of a historical wooden structure. |

Structural Damage Detection in a Steel Column-Beam Joint Using Piezoelectric Sensors |
|
Carlos Humberto Cuadra, Nobuhiro Shimoi(Akita Prefectural University, Japan) |
| In this research, application of piezoelectric sensors to detect structural damage due to seismic action on building structures is investigated. Film-type piezoelectric sensor was developed and proposed for this task. This film-type piezoelectric sensor was attached to a thin steel plate that was set up at a steel column-beam joint of a test specimen that was subjected to bending moment. Potential applicability of this piezoelectric sensors to detect structural damages was verified. |

Robust optimization of the production profile of the steam assisted gravity drainage reservoir using a polynomial chaos expansion-based proxy model |
|
Ajay Ganesh(University of Alberta, Canada) |
| In this work, a stochastic proxy model was developed for the output cumulative oil production of a steam assisted gravity drainage process at different input steam injection rates using Legendre and Hermite polynomial functions that can be used to compute and propagate uncertainty from input to output in the presence of parametric uncertainty. A second order Polynomial Chaos Expansion (PCE) model developed was further used for robust optimization of cumulative oil production. This work was a demonstration of the possibilities of integrating PCE modeling and robust optimization. |

Evaluating Successive Linearization in NMPC for Controlling Oscillations in Boiling Channel |
|
Koustav Roy, Swapan Paruya, Jyoti Bhati(National Institute of Technology, Durgapur, India) |
| In the present paper, the performance evaluation has been carried out at different forcing frequencies and difference control horizons. The open loop response of the boiling channel indicates that the control becomes difficult at resonance frequency. However, the present study therefore concentrates on the control of DWOs at resonance frequency using SL-NMPC and NLP-NMPC. Interestingly, the relative performance and relative stability of SL-NMPC have been found to decrease with increase in control horizon when compared with NLP-NMPC. |

Basics of creating platforms for automation of business processes of logistics |
|
Raissa Kabievna Uskenbayeva, Abu Abdikadyrovich Kuandykov, Sabina Batyrkhanovna Rakhmetulayeva, Aigerim Bolshibayeva(International IT University, Kazakhstan) |
| Тhis paper consider a platform for logistics business processes. Details of the complex formulation of the problem of creating an optimal platform and methods of problem solving to create a platform. In this paper, the authors propose an integrated platform that should lead the process of forming a business process and its automation system at the same time, since the connection between business processes and its automation systems is cross-over. At automation of specialized business processes it is necessary to correct so that they (ie business operations) were adapted to automation. |
