Detailed information about various gamma-ray shielding parameters (GSP) is required to investigate the building's gamma-ray shielding efficacy. The computer plays an essential role in such investigations by calculating the GSP. The multi-layered shields provide better shielding efficacy than the single-layered protectors. This work aims to describe the development of an online-platform to calculate 36 GSP for both types of shields. A computer code for the platform has been written in Python and named as Py-MLBUF. It calculates the GSP, in the energy range 0.015-15 MeV. One can use the developed platform free of cost from https://***. It is accessible from computers and smartphones. The added features like fast calculation speed, higher accuracy, graph plotting capability, analyzing and suggesting an improvement in shielding efficacy, and sending the results via e-mail, make it unique. Py-MLBUF will serve as a free interactive educational tool to provide free research consultancy in improving radiological safety. (C) 2020 Elsevier Ltd. All rights reserved.

A computer code for analyzing the safety feature of triso coated particles for high temperature reactor has been developed based on PANAMA code. This python based code were separated into several modules to perform the main TRIAC-BATAN and linear interpolation calculation, to read the input data file, and to control the sequence of all TRIAC-BATAN calculation. In this initial development phase, TRIAC-BATAN can produce similar pattern as PANAMA calculation in the case of failure fraction of triso particles, either for Depressurized Loss Of Forced Cooling (DLOFC), 100 degrees C higher than DLOFC temperature and constant accident temperature at 1600 degrees C. By using the euclidean distance, TRIAC-BATAN calculation and PANAMA for DLOFC condition are separated in around 3.23.10(-7).

Stability analysis of the north-eastern slope of Daralou copper open pit mine against a secondary toppling failure

ENGINEERING GEOLOGY 2019年 249卷 89-101页

Secondary toppling failures have complicated mechanisms. In these instabilities, some natural or manmade external factors motivate and overturn a rock mass. One of the most common types of secondary toppling failures is slide-toe-toppling mode. When a blocky or layered rock mass is overlaid by a soil or weak rock mass, the combination of a toppling failure in the rock at the toe and a circular or non-circular sliding in the soil or weak rock in the top leads to this hybrid failure. In 2015, such failure occurred in north-eastern slope of Daralou copper open pit mine. During this instability, the slope consisted mainly of two 10-m benches and one 4-m semi-bench. Since it was supposed to excavate the slope to the depth of 54 m, experts were worried about the project facing a similar larger failure in the future. Hence, a widespread investigation was carried out on the failure. Firstly, the mechanism of this instability was clarified with geological and geotechnical surface and subsurface investigations. Next, existing analytical solution which had been presented for analysis of static slide-toe-toppling failure was modified and some new equations were obtained for analysis of the failure under dynamic condition. Then, a computer code was developed based on the new equations for evaluation of the instability. In the next step, the failed slope was analyzed using the code and finite element method, and outcomes of these analyses were compared with real conditions. The comparison showed that there was satisfactory agreement between the analytical, numerical and actual results. Therefore, these methods were used to predict the behavior of the final slope in static and dynamic conditions. These evaluations indicated that if displaced materials are completely excavated and removed from the mine and overall dip of the slope is reduced, the final slope will be stable against slide-toe-toppling failure. This paper summarizes the results and concludes that both the modified ana

Recent advances for prediction of electric spark and shock sensitivities of organic compounds containing energetic functional groups to assess reliable models

PROCESS SAFETY AND ENVIRONMENTAL PROTECTION 2019年 131卷 9-15页

For organic compounds containing energetic groups, electric spark (electrostatic or electrostatic discharge) and shock sensitivities can initiate their decomposition process in chemical industries and applications. Electrostatic charges often accumulate in bulk explosives and equipment during handling and processing procedures. They may provide hazardous explosion due to tribocharging. Since more reliable experimental methods have been developed in recent years for measurements of these sensitivities, some reliable methods have also been introduced for their predictions. This work reviews the recent models for prediction of electric spark sensitivity of some classes of organic and ionic liquid energetic compounds as well as shock sensitivity. A novel easy to handle and user-friendly computer code is also introduced to predict electric spark and shock sensitivities by suitable and reliable predictive methods for some classes of high explosives including polynitro arene and nitramine compounds. The computer code has been checked for some newly reported energetic compounds, where their experimental data were available, which provide reliable predictions.

Simulation and performance improvement of cryogenic distillation column, using enhanced predictive Peng-Robinson equation of state

引用

FLUID PHASE EQUILIBRIA 2019年 489卷 117-130页

作者： Larijani, Morteza Ardeshir Bayat, Mohamad Afshin, Hossein Sharif Univ Technol Sch Mech Engn CEEC Tehran Iran

In this study, a cryogenic distillation column has been designed and simulated via a computer code based on the theta method of convergence. The required thermodynamic properties are determined from the enhanced predictive Peng-Robinson (E-PPR 78) equation of state which has a good accuracy in predicting the corresponding thermodynamic properties of natural gas components. The combined code of distillation column/equation of state has been verified with that of another study. In the present study, the results are achieved by the constant molar over-flow and inclusion of energy equations assumptions. In order to have more accuracy in the results, the energy equations were considered in the column calculations. For improvement of column operational conditions, a parametric study is carried out. The results show that by the proper selection of reflux ratio, column operating pressure, feed plate location and considering energy constraints, the molar concentration of methane is decreased from 66.14% in the initial state to 13.75% in the improved state.

The current activity envisages the evaluation of radial temperature distribution in mixed oxide fuels (MOX) using two computer codes: finite element commercial computer code ANSYS and the thermo-mechanical computer program, TRANSURANUS, developed by the Institute for Transuranium Elements (ITU), Karlsruhe, Germany. In this paper, was introduced RADAR (RAting Depression Analysis Routine) model of Palmer - 1982 in ANSYS code, in order to asses radial power distribution in MOX fuel. Moreover, present work involves also the implementation, in both codes, of a thermal conductivity correlation, taken from the literature. When a model or correlation is incorporated into a computer code, the user become responsible for its maintenance. Therefore, in this paper, verification by comparisons with experiment and code-to-code comparison are provided. The use of RADAR model along with HALDEN thermal conductivity correlation, proved to be fast and reliable. The overall picture indicates adequate TRANSURANUS and ANSYS simulations, against experimental data.

The authors continue to study the influence of the tsunami source parameters on the distribution of the wave maximal heights along the nearest coastline. Numerical tests are based on the real digital bathymetry at southern part of Japan. Mesh step is compared to 300 m in both directions. Certainly, it is not enough for inundation mapping, but quite suitable for fast evaluation of positions of wave maximal heights. All numerical tests were arranged at regular PC with a hardware accelerator, based on Field Programmable Gates Array microchip (FPGA). As was observed, both position of the sea bed initial displacement and the shape of such displacement are important. Observed phenomenon is discussed in numbers.

Automation and autonomous systems are becoming increasingly pervasive in society, as are the software systems that control them. There is a need for safe and secure software systems. Automated code repair provides a promising solution. The present research investigates programmers' perceptions of trustworthiness and trust in automated code repair, how those perceptions and intentions differed from code ostensibly repaired by a human, and the effects of repair transparency. The present research comprises two studies, each with a unique sample. The first sample included inexperienced developers (N = 24), and the second sample included experienced developers (N = 24). Participants were presented with five different pieces of code before and after being repaired by an automated code repair program, and were asked to rate the trustworthiness of the repairs and whether they would endorse using the code. Each study was a 2 x 2 between-subjects design with repeated measures. The first factor manipulated the purported source of the repairs (human vs automated code repair program). The second factor manipulated the transparency of the repairs (deleted vs commented out). Results suggest that inexperienced developers find automated code repair more trustworthy than repairs made by a human. Both experienced and inexperienced developers trusted the human repairer less after reviewing the repairs, but did not significantly differ in their intentions to trust the automated code repair program after reviewing the repairs.
