Examining association between construction inspection grades and critical defects using data mining and fuzzy logic

Abstract: This paper explores the relations between defect types and quality inspection grades of public construction projects in Taiwan. Altogether, 499 defect types (classified from 17,648 defects) were found after analyzing 990 construction projects from the Public Construction Management Information System of the public construction commission which is a government unit that administers all the public construction. The core of this research includes the following steps. (1) Data mining (DM) was used to derive 57 association rules which altogether contain 30 of the 499 defect types. (2) K-means clustering was used to regroup the 990 projects of two attributes (defect frequency and original grading score of each project) into four new quality classes, so the 990 projects can be more evenly distributed in the four new classes and the correctness and reliability of the following analyses can be ensured. (3) Finally analysis of variance (ANOVA), fuzzy logic, and correlation analysis were used to verify that the aforementioned 30 defect types are the important ones determining inspection grades. Results of this research can help stakeholders of construction projects paying more attention on the root causes of the critical defect types so to dramatically raise their management effectiveness.

Transformation with Optics

Abstract: Publisher Summary This chapter discusses the relation between mathematical transformations and optics Mathematical transforms are closely related to the history of the development of optics Fourier optics with the concept of Fourier transform and spatial-frequency spectrum analysis is now a fundamental basis of optical system analysis and design Three transforms are introduced in this chapter They are: the physical wavelet transform, the Wigner distribution function, and the fractional Fourier transform There are a large number of optical processors and systems developed for implementation of a variety of transforms for optical signal processing and pattern recognition Most optical systems, such as imaging systems and laser resonators, are circularly symmetrical, or axially symmetrical In these cases, the use of the polar coordinate system is preferable, and the two dimensional Fourier transform expressed in the polar coordinate system will lead to the Hankel transform, which is widely used in the analysis and design of optical systems The Hough transform is a specific geometrical transform and is a special case of the Radon transform Most Hough transforms have been performed in digital image processing

Leverage big data analytics for dynamic informed decisions with advanced case management

Abstract: Big data is transforming the world, and it’s especially changing the way in which modern enterprises conduct business and strategic, informed decisions. By incorporate big data analysis, organisations can make decisions based on facts rather than intuition or hidden internal knowledge. When decision makers and knowledge workers have access to increasingly accurate and up-to-date trusted source of information, along with the analytical tools to make sense of it, their organisations benefit from more informed decisions and more consistent outcomes than ever before. This approach for supporting decisions can affect overall company’s business and the way knowledge workers do their jobs. Analytic tools took insights from big sets of data. They help broaden the context and background available for making informed, accurate, and consistent decisions. This research renders how Big Data analysis can extend the DSS part of the Adaptive Case Management (ACM) systems. Authors of the article discusses the thes...

Dynamic calibration of piezoelectric transducers for ballistic high-pressure measurement

Abstract: The development of a dynamic calibration standard for high-amplitude pressure piezoelectric transducers implies the implementation of a system which can provide reference pressure values with known characteristics and uncertainty. The reference pressure must be issued by a sensor, as a part of a measuring chain, with a guaranteed traceability to an international standard. However, this operation has not been completely addressed yet until today and is still calling further investigations. In this paper, we introduce an experimental study carried out in order to contribute to current efforts for the establishment of a reference dynamic calibration method. A suitable practical calibration method based on the calculation of the reference pressure by measurement of the displacement of the piston in contact with an oil-filled cylindrical chamber is presented. This measurement was achieved thanks to a high speed camera and an accelerometer. Both measurements are then compared. In the first way, pressure was generated by impacting the piston with a free falling weight and, in the second way, with strikers of known weights and accelerated to the impact velocities with an air gun. The aim of the experimental setup is to work out a system which may generate known hydraulic pressure pulses with high-accuracy and known uncertainty. Moreover, physical models were also introduced to consolidate the experimental study. The change of striker’s velocities and masses allows tuning the reference pressure pulses with different shapes and, therefore, permits to sweep a wide range of magnitudes and frequencies.
