Chinese Journal of Traumatology 2014年第6期17卷 351-353页

作者： mohammad Asl zare Ali Kamalati Saeed Esmailnia Department of Urology Faculty of Medicine Mashhad University of Medical Sciences Mashhad Iran Department of Urology Faculty of Medicine Kerman University of Medical Sciences Kerman Iran

Vesicovaginal fistula （VVF） may be caused by prolonged obstructed labor, gynecologic, urologic, or other pelvic surgery, malignancy, radiation, infection and trauma. Here we report a case of VVF caused by nail penetrating trauma in a young woman with genital bleeding after first intercourse. This is a rare etiology of VVF. We also explain the operative technique used to repair the fistula.

Auto-tuning PVT data using multi-objective optimization: Application of NSGA-Ⅱ algorithm

引用

Petroleum 2024年第1期10卷 135-149页

作者： Abdolhadi Zarifi mohammad Madani mohammad Jafarzadegan Reservoir Engineering Systems Petroleum Engineering Department Main Office Building of National Iranian South Oil Company (NISOC) Combined Planning Management National Iranian Oil Company (NIOC) Reservoir Engineering Division Petroleum Engineering Department Petroleum Engineering and Development Company (PEDEC)

Reservoir simulation is known as perhaps the most widely used, accurate, and reliable method for field development in the petroleum industry. An integral part of a reliable reservoir simulation process is to consider robust and rigorous tuned EOS models. Traditionally, EOS models are tuned iteratively through arduous workflows against experimental PVT data. However, this comes with a number of drawbacks such as forcingly using weight factors, which upon alteration adversely affects the optimization *** objective of the current work is thus to introduce an auto-tune PVT matching tool using NSGA-II multi-objective optimization. In order to illustrate the robustness of the presented technique, three different PVT samples are used, including two black-oil and one gas condensate sample. We utilize PengRobinson EOS during all the manual and auto-tuning processes. Comparison of auto-tuned EOS-generated results with those of experimental and computed statistical error values for these samples clearly show that the proposed method is robust. In addition, the proposed method, contrary to the manual matching process, provides the engineer with several matched solutions, which allows them to select a match based on the engineering background to be best amenable to the problem at hand. In addition, the proposed technique is fast, and can output several solutions within less time compared to the traditional manual matching method.

引用

Optoelectronics Letters 2024年第7期20卷 406-411页

作者： mohammad Ghanavati mohammad Azim Karami School of Electrical Engineering Iran University of Science and Technology

We developed a plasmonic refractive index（RI） with a metal-dielectric-metal（MDM） structure that utilizes two Persian Orsi windows-like separated cavities with a high figure of merit（FoM） and ultrasensitivity. The simulated and optimized Ag-air-Ag MDM sensor for surface plasmon resonance（SPR） offers high RI sensitivity（SRI） and the ability to detect blood plasma concentration（BPC）. The results verified that structural parameters have an effect on S;RI;, full width at half maximum（FWHM）, FoM, sensitivity of blood plasma（S;p;） for right and left peaks, whose values are 1 345.45 nm·RIU;-1;, 32 nm, 42.04 RIU;-1;, 0.26 and 0.19 nm·L·g;-1;, respectively. The proposed design opens a new horizon in sensor development.
