Accuracy Analysis Of Earthwork Calculation Based On Triangulated Irregular Network (Tin)
In most of conventional methods for calculating earthwork, the assessment of accuracy contains many uncertainties. This paper discusses the relationship between the accuracy of terrain data and that of the earthwork calculation. The main research method is propagation of error, and a formula is created which expresses the quantity relationship that how the errors of terrain data effects the acc...
متن کاملCalculation of Leakage in Water Supply Network Based on Blind Source Separation Theory
The economic and environmental losses due to serious leakage in the urban water supply network have increased the effort to control the water leakage. However, current methods for leakage estimation are inaccurate leading to the development of ineffective leakage controls. Therefore, this study proposes a method based on the blind source separation theory (BSS) to calculate the leakage of water...

متن کاملAbsorbed Dose Calculation In Irregular Blocked Radiation Fields: Evaluation of Clarkson’s Sector Integration Method for Radiation Fields Commonly Used in Conventional Radiotherapy
Introduction: Irregular/blocked fields are routinely used in radiotherapy. The doses of these fields are usually calculated by means of equivalent square method that is inherently prone to uncertainty. On the other hand, Clarkson’s sector integration method is a dose calculation method which offers far better accuracy in dose calculation of irregular fields. The Scatter Air Ratio (SAR) of an in...
