Nader Javanmardi Nabikandi,Shohreh Fatemi 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.30 No.-
Kinetic modelling of a sulfur recovery unit based on straight through sour natural gas was performed bynumerical programming and the model outlet results were compared with industrial data. A recovery of97.4 mole% sulfur was observed from this unit. It was revealed that kinetic model precisely predicted the outlet results of sulfur, H2S, SO2 and CO2with 4% absolute relative deviation in combustion furnace and 2% in catalytic convertors. Theequilibrium model has shown 3% deviation for prediction of H2S/SO2 ratio from the furnace, whereas thekinetic model has shown only 0.2% deviations from the real results.

HIGH DEFINITION MAP AIDED OBJECT DETECTION FOR AUTONOMOUS DRIVING IN URBAN AREAS
Endo Yuki,Javanmardi Ehsan,Gu Yanlei,Kamijo Shunsuke 한국자동차공학회 2023 International journal of automotive technology Vol.24 No.2
Detecting object locations and semantic classes in an image, such as traffic signs, traffic lights, and guide signs, is the crucial problem for autonomous driving, known as object detection. However, stable object detection in complex real-world environments, such as urban environments, is still challenging because of clutter, time of day, blur etc., even with modern deep convolutional neural networks (DCNNs). On the other hand, a high definition (HD) map is a pre-built information resource for autonomous driving tasks, especially for controls. Besides controls, HD map utilization for detection tasks has been gaining attention in recent years, enabling us to stabilize detection even in complex real-world environments. However, it is challenging to use object information from an HD map as detection directly because the self-localization error affects the transformed object locations on the image coordinate system from the HD map’s coordinate system. This paper explores incorporating HD map information into deep feature maps of a DCNN-based model. Two proposed modules implicitly make the feature extraction efficient and stable by utilizing HD map information. As a result of the experiments, the proposed module improved a modern model for challenging images of the urban area Shinjuku by 37 % in mAP, even in self-localization errors.

Following three well-established approaches, different modifications have been proposed that significantly improve the Peng-Robinson EOS’s predictions of the volumetric properties of carbon dioxide in the supercritical region. By making use of 5301 experimental PVT data points of supercritical carbon dioxide (SC-CO2), three models have been developed based on the volume-translation concept, modification of the alpha function of the attractive term of the Peng-Robinson EOS and the addition of a third translation parameter to the EOS. The experimental data considered encompass a wide temperature and pressure range of 304.35-1,273.15 K and 7.38-800.00MPa, respectively. According to the results from several graphical and statistical analyses, the proposed models can reliably be employed for prediction and representation of the volumetric properties of SC-CO2 with AARDs below 1.3%. Comparisons have also been made with the modified Redlich-Kwong EOS as well as the standard reference multiparameter EOS developed by Span and Wagner, demonstrating the comparable accuracy of the proposed models, while offering notably simpler mathematical formulation.

Natural deep eutectic solvents (NADESs) as green solvents have substantial potential for enhancing the solubility of pharmaceuticals in aqueous solutions. In this work, the solubility of two B vitamins (nicotinic acid and 4aminobenzoic acid) in aqueous solutions of two NADESs was measured at temperatures between 298.15 K and 313.15 K and different concentrations of NADESs. The studied NADESs were prepared by mixing dried choline chloride with urea or malonic acid with molar ratios of 1 : 2 and 1 : 1, respectively. Based on the results, chloride+malonic acid was more effective on the solubility of the pharmaceuticals in aqueous solutions. Furthermore, the DESs increased the aqueous solubility of 4aminobenzoic acid more than that of nicotinic acid. The experimental solubility data were modeled with the van Laar activity model as well as the modified Apelblat equation to correlate the solubility of the pharmaceuticals to the temperature and NADESs concentration. The molar enthalpy of dissolution (hd) and the molar enthalpy of mixing (hmix) of the pharmaceuticals in the aqueous solutions of the NADESs were calculated. These parameters showed that all the dissolution processes were endothermic, while the mixing process as a part of the dissolution process was exothermic.

Gastrointestinal cancers remain the most prevalent cancers in many developing countries such as Iran. The aim of this study was to estimate incidence, prevalence and mortality, as well as time trends for gastrointestinal cancers in Isfahan province of Iran for the period 2001 to 2010 and to project these estimates to the year 2020. Estimates were driven by applying the MIAMOD method (a backward calculation approach using mortality and relative survival rates). Mortality data were obtained from the Ministry of Health and the relative survival rate for all gastrointestinal cancers combined was derived from the Eurocare 3 study. Results indicated that there were clear upward trends in age adjusted incidence (males 22.9 to 74.2 and females 14.9 to 44.2), prevalence (males 52.6 to 177.7 and females 38.3 to 111.03), and mortality (males 14.6 to 47.2 and females 9.6 to 28.2) rates per 100,000 for the period of 2001 to 2010 and this upward state would persist for the projected period. For the entire period, the male to female ratio increased slightly for all parameters (incidence rate increased from 1.5 to 1.7, prevalence from 1.4 to 1.6, and mortality from 1.5 to 1.7). In males, totals of 2,179 incident cases, 5,097 prevalent cases and 1,398 mortality cases were predicated to occur during the study period. For females the predicted figures were 1,379, 3,190 and 891, respectively. It was concluded that the upward trend of incidence alongside increase in survival rates would induce a high burden on the health care infrastructure in the province of Isfahan in the future.
