Simulations and measurements

The paper presents the characteristics of the ISO-4037 narrow spectrum X-ray reference fields in 02 different manners: simulation using the SpekPy and measurement using a calibrated ionization chamber. The physical (air Kerma rate) and radiation (X-ray fluence-spectrumaveraged energy, the first and the second half value layers, as well as the beam homogeneity coefficient) quantities were simulated using the SpekPy web-based simulation toolkit.

The experimental flux-weighted average cross section is compared with the theoretical prediction, for which the absolute cross section was calculated using the TALYS 1.95 code and the bremsstrahlung spectrum was simulated using the computer program MCNPX. The present experiment was carried out at the 100 MeV electron linac of the Pohang Accelerator Laboratory, POSTECH, Pohang, Korea.

The article presents numerical simulation results for tunnel collapse prediction using the Disctinct Element Method (DEM). The results of the study show that the use of DEM enables simulation of the collapse mechanism and prediction of its potential collapse extent in underground tunnel construction. Based on the simulation results, suitable measures to prevent a possible collapse could be proposed and planned.

This study utilized the GIS-based Soil and Water Assessment Tool (SWAT) model to simulate the flow of Vu Gia - Thu Bon river basin at two hydrological stations - Nong Son and Thanh My, during the calibration period (2004 - 2010) and the verification period (2011 - 2015). The evaluation results of both periods, as measured by the NSE and R2 indexes, were found to be above 0.75.

In this study, a performance of shrimp paste production is measured by using simulation approach. A discrete event simulation model is developed to illustrate the processes in the production line which involved four major processes. From the model, it is estimated that the average process time taken to produce 2000 pieces of shrimp paste is 235.13 minutes while the average waiting time taken in the operation system is 89.21 minutes. The findings also show that the bottleneck of the production process is found to be at packaging process and some of the resources are not fully utilized.

In ebook "Pore structure in food: Simulation, measurement and applications" the pore structure of foods directly affects the success of such food processes as drying, puffing, freeze-drying, and rehydration. Consequently, the pore structure of foods determines what types of food processes will work best with a particular food. This Brief will first discuss in depth the need to correctly measure the pore structure of foods and then will identify and describe in detail the current methods available to measure food porosity. Finally, it will review the applications of these various methods. ​

Mycotoxins are toxic food pollutants that are created naturally by some fungus. By contaminating food, they have a harmful impact on human health. This study's major objective was to simulate food products from bakeries being contaminated. Separate bakery food samples were examined to see whether fungus and associated mycotoxins were present.
