Optimizing the Global Digital Elevation Models(GDEMs) and accuracy of derived DEMs from GPS points for Iraq’s mountainous areas

引用

Geodesy and Geodynamics 2020年第5期11卷 338-349页

作者： Shazad Jamal Jalal Tajul Ariffin Musa taher Hama Ameen Ami Hassan Md Din Wan Anom Wan Aris Jwan Mohammad Ebrahim Faculty of Built Environment and Surveying Universiti Teknologi Malaysia Johor Bahru 81310 Malaysia College of Engineering University of Sulaimani 46001 Sulaimani Iraq University of Arkansas at Little Rock Little Rock 72204 AR USA SALP Middle East Ltd. Company for Oil and Gas Pipeline Construction Erbil Iraq

Optimizing the combined horizontal and vertical accuracy of the well-known Global Digital Elevation Models(GDEMs) of various resolutions for each country and region especially in Iraq’s mountainous areas is still questionable. All the three GDEMs, approximately, have the same vertical accuracy with the Root Mean Square(RMSE) of ±7.3 m, ±7.6 m and ±6.5 m via 12 fixed Ground Control Points(GCPs) for the Advanced Land Observation Satellite Phased Array L-band Synthetic Aperture Radar(ALOS PALSAR 12.5 m), the Shuttle Radar Topographic Mission(SRTM 30 m) and the TerraSAR-X(the name of twin satellites) add-on for Digital Elevation Measurement(TanDEM-X 90 m) GDEMs respectively. Moreover, the percentage of outliers that are greater or smaller than ±10 m detection of the height extraction from both the ALOS PALSAR and SRTM Digital Elevation Models(DEMs) contains 16.7% and for TanDEM-X was 25%. In this paper,the special DEM is derived using 2123 handheld GPS points for Sulaymaniyah Governorate, Kurdistan region, Iraq. The height extraction by discarding the outliers of 58% gives the RMSE of ±8.0 m in the case of adding geoid heights(N) to the ellipsoidal heights(h) via the Earth Gravitational Model 2008(EGM2008)and ±5.6 m without adding N. It is expected that the derived DEMs will give more accurate results both horizontally and vertically in the mountainous areas when GPS observations are intensified. The horizontal accuracy is validated through extracting hierarchy stream types of the watershed map from the DEMs for higher than 100 pixels length. The ALOS PALSAR DEM extracted more numbers of stream orders than ***, based on the criteria of RMSE, outlier detection, and the number of extracted stream orders, the ALOS PALSER DEM is regarded as the optimal GDEM in comparison with the close accuracy of both the TanDEM-X and SRTM DEM.

Heat Transfer Enhancement of Cu-H<sub>2</sub>O Nanofluid with Internal Heat Generation Using LBM

引用

Open Journal of Fluid Dynamics 2013年第2期3卷 92-99页

作者： Mohammad Abu taher Yeon Won Lee Heuy Dong Kim School of Mechanical Engineering Andong National University Andong South Korea School of Mechanical Engineering Pukyong National University Busan South Korea

Fluid flow and heat transfer analysis of Cu-H2O nanofluid in a square cavity using a Thermal Lattice Boltzmann Method (TLBM) have been studied in the present work. The LBM has built up on the D2Q9 model and the single relaxation time method called the Lattice-BGK (Bhatnagar-Gross-Krook) model. The effect of suspended nanoparticles on the fluid flow and heat transfer analysis have been investigated for different non dimensional parameters such as particle volume fraction (φ) and particle diameters (dp) in presence of internal heat generation (q) of nanoparticles. It is seen that flow behaviors and the average rate of heat transfer in terms of the Nusselt number (Nu) as well as the thermal conductivity of nanofluid are effectively changed with the different controlling parameters such as particle volume fraction (2% ≤ φ ≤ 10%), particle diameter (dp = 5 nm to 40 nm) with fixed Rayleigh number, Ra = 105. The present results of the analysis are compared with the previous experimental and numerical results for both pure and nanofluid and it is seen that the agreement is good indeed among the results.

面对新世纪的挑战，各国都强烈意识到教育对社会发展的重要性，在世界范围内兴起了新一轮课程改革，“他山之石，可以攻玉”，为了更好地认识本国基础教育的优势与不足，借鉴其他国家的成功之处，应加强课程比较研究。巴林教育在阿拉伯世界尤其是在海湾地区具有鲜明的代表性，甚至在一段时期(上世纪90年代—2002年)巴林与其他海湾国家实行统一的课程标准和教材，中国教育的历史悠久，在东亚国家中也具有一定的代表性。目前，两国都颁布了新的课程标准(文件)，正在试验新的教材，课程改革正成为广大科学教育工作者的鲜活实践。本文选取巴林和中国初中物理课程作为比较研究的对象，文中对比较教育进行了理论综述，简略回顾了巴中两国初中物理课程的发展概况;从文本课程的角度研究了两国的初中科学(物理)课程标准和有代表性的教材，对两国的初中物理课程设计、课程目标、课程内容、教材设计、教材编写等进行了深入比较、分析;根据笔者作为巴林中学物理教师的教学体验和对中国初中物理教学的考察，对巴中两国初中物理教学实况进行了客观的记述和比较。据此，反思巴中两国初中物理课程中的优势与不足，为两国初中物理课程的改革分别提出了相应的建议，希望通过这一研究增进巴中两国教育的理解和交流，促进初中科学课程的改革。

Dosimetric Comparison between Three Dimensional Conformal Radiation Therapy (3DCRT) &Intensity Modulated Radiation Therapy (IMRT) in Mid-Lower Oesophageal Carcinoma

引用

International Journal of Medical Physics, Clinical Engineering and Radiation Oncology 2019年第2期8卷 121-129页

作者： Azza N. taher Rasha A. Elawady Amr Amin The Department of Radiation Oncology National Cancer Institute Cairo University Cairo Egypt The Unit of Radiation Physics Department of Radiation Oncology National Cancer Institute Cairo University Cairo Egypt

Purpose: To investigate if intensity modulated radiation therapy (IMRT) offers a better planning target volume (PTV) coverage and/or lower dose to normal thoracic structures in comparison to three dimensional conformal radiation therapy (3DCRT) in the treatment of mid and lower oesophageal carcinoma patients. Materials and Methods: A prospective study in the period from 2014 till 2015 was held in the radiation therapy department of the National Cancer Institute, Cairo University, in which 20 locally advanced or inoperable mid and lower oesophageal cancer patients were treated by chemo-radiation using 3DCRT technique. IMRT plans were generated for those 20 patients. The 3DCRT and IMRT plans were compared as regards PTV coverage and doses to critical organs at risk. Results: All plans had produced satisfactory PTV coverage with no significant differences noted. The lung V20 for both lungs in 3DCRT was 16.94% ± 4.2% which was increased to 21.42% ± 3.6% in IMRT (p = 0.017). The mean dose to the heart and V30 were higher in IMRT plans while the mean dose to the spinal cord was higher with 3DCRT plans, yet that didn’t reach a statistically significant level (p = 0.156). The dose delivered to the liver didn’t pose any difference between both techniques. Conclusion: 3DCRT remains to be a feasible cost effective treatment delivery option for mid and lower oesophageal cancer cases with a lower optimization and delivery time than that for IMRT. Moreover, that calls for further dosimetric studies and clinical trials to assess IMRT technique. In our study, IMRT using nine fields didn’t prove to be superior to 3DCRT.

International Journal of Geosciences 2012年第4期3卷 675-682页

作者： Amira Ayed-Khaled taher Zouaghi Mohamed Ghanmi Fouad Zargouni Université de Carthage Université Tunis El Manar

Gravity data associated with surface geology in the Northern Tunisian Atlas offer better understand to the underlying structures in Teboursouk area and to highlight other deep or unknown structures in surface. The gravity study was based on qualitative and quantitative analysis including the construction of the gravity Bouguer anomaly, upward continuations, residual anomaly, and Horizontal gradient maxima maps. The main results display many positive and negative anomalies as the response of geological structures (J. Cheid Triassic structure, Khalled plain, El Aroussa plain). In addition, the horizontal gradient maxima integrated with geological and structural maps let the identification of major directions of gravimetric lineaments in the study area us NE-SW trending features at the boundaries of J. Cheid structure, NW-SE direction that limit Gaafour plain and Tabet Ech Cherif syncline, and N-S trending that bordered El Aroussa basin. Major results allowed the construction of a new structural map of the study zone.
