Monitoring and Change Detection along the Eastern Side of Qena Bend, Nile Valley, Egypt Using GIS and Remote Sensing

引用

Advances in Remote Sensing 2013年第3期2卷 276-281页

作者： Ahmed Omar abd El-aziz Senior of Geomatics-Al-Amar Consulting Group Cairo Egyp

This Article is set to track and monitor changes through spatial dependence of remote sensing data and GIS analysis, the suggested working method in this research is by sub pixel classification techniques. Change detection is a central task for land cover monitoring by remote sensing. It uses multi temporal image data sets in order to detect land cover changes from spectral discrepancies [1] (Rafael, et al.). It discusses the study perception of the situation in the past as well as the current and finally the future status of changes that land uses in Eastern Qena meander specifically in places of estuary floods, and the most important estuary leading to Qena, and whether these changes in land are used in direction of the mouth of the stream or not, especially that when it happened before, it caused destruction of both activities, urban & agricultural land. It will rely on Landsat images in years of (1972-2012), conduct analysis, different classifications integration with geographic information systems (GIS), and field as well as samples for the accuracy assessment.

The anti-correlation method for removing harmonic distortion in vibroseis slip-sweep data

引用

Applied Geophysics 2012年第2期9卷 159-167,234页

作者：张红静周辉 abd E1-aziz Khairy abd E1-Aal 张洁油气资源与探测国家重点实验室 CNPC物探重点实验室中国石油大学(北京) National Research Institute of Astronomy and Geophysics(NRIAG) Department of SeismologyHelwan11722 CairoEgypt 中国石化石油物探技术研究院

The slip-sweep technique is one of the high-efficiency, high-fidelity, and environmental vibroseis seismic prospecting techniques which consists of a vibrator group sweeping without waiting for the previous group＇s sweep to terminate. The cycle time can be reduced drastically and hence the production efficiency can be increased significantly but harmonic distortion of one sweep will leak into the record of the other sweep. In this paper, we propose an anti-correlation method for removing harmonic distortion in vibroseis data. This method is based on decomposition of the ground force signal into fundamental and harmonic components. Then the corresponding anti-correlation operator can be computed to estimate the energy of each harmonic after correlating the vibroseis data with the corresponding harmonic component. Finally, the vibroseis harmonic noise to be removed can be obtained by subtracting the extracted harmonic noise from the traces of the previous group＇s sweep. The advantage of the proposed method is that it can process both uncorrelated and correlated vibroseis seismic data. Moreover, the algorithm is simple, stable, and computationally fast. Especially, the significant contribution of this method is a considerable reduction in the harmonic without any alteration of the desired signals. The method was tested on both synthetic and field data sets to validate the good harmonic noise suppression results.

Legal Framework of Shari＇ah Corporations in Malaysia： Special Reference to Waqf Corporation

引用

Journal of Modern Accounting and Auditing 2017年第3期13卷 121-127页

作者： Zuhairah Arifabd Ghadas Hartinie binti abd aziz University of Sultan Zainal Abidin Terengganu Malaysia

In Malaysia, the Islamic commercial institutions were established under respective legislations which contain express term on their status as a body corporate. Examples of these institutions are Islamic banks, zakah institutions, Pilgrimage Board and Islamic insurance （takaful） companies. In 1998, Johor Corporation （JCorp） initiated a corporate waqf entity known as Waqaf An-Nur Corporation Berhad （WANCorp）. In 2011, Majlis Agama Islam Wilayah Persekutuan （MAIWP） collaborated with Tabung Haji to develop a Class AWaqf building leased to Bank Islam Malaysia Berhad （BIMB）. The developments in waqf involving corporate entities are worth to be analyzed in order to create a new framework of waqf practice. This paper deliberated the attributes of corporations under the Malaysian law and compares them with the principles of Islamic law （Shari＇ah）. For the purpose of discussion, this paper refers to WANCorp and Awqaf Holdings as examples ofwaqf corporations in Malaysia.

Comparing Point Counting & Image Analysis in Sandstone North Carnarvon Basin, Australia

Comparing Point Counting & Image Analysis in Sandstone North...

引用

第五届全国计算机数学学术会议

作者： Ilyah abd.aziz Hess Oil & Gas Sdn. Bhd./Universiti Malaya

Point counting is a statistical method of estimating the proportion of different mineral occurrences and porosity in a thin section slide using a petrographic microscope. Image analysis can be used for the same purpose but uses computer imaging technology and thin section photomicrographs.A study comparing these two methods was performed on three wells in the North Carnarvon Basin, WNW Australia. Both methods produced similar results; however, the image analysis technique is much faster,needs little expertise and only requires a PC and thin section photomicrographs. This makes the image analysis method much more accessible to most working geoscientists. The results can be very helpful for checking routine core analysis results and for differentiating micro- and macro- porosity systems.
