A Hybrid Method for Edge Continuity Based on Pixel Neighbors Pattern Analysis (PNPA) for Remote Sensing Satellite Images

引用

International Journal of Communications, Network and System Sciences 2012年第9期5卷 624-630页

作者： Waqas Haider Muhammad Sharif Malik Mudassar Raza abdul wahab Izhar Ahmed Khan Umar Zia Jawad Tanveer Hadia Bashir Department of Computer Science COMSATS Institute of Information Technology Wah Cantt and Vehari Campus Pakistan

Edge enhancement is derived from lack of accurate result from edge detection techniques. The image which is captured from long distances carries a lot of noise and blur which causes edge discontinuity. Although some novel algorithms which are based on cellular neural network, fuzzy enhancement and binary morphology have shown accuracy in order to obtain refined edge but still the problem of edge discontinuity arises. Eliminating discontinuity of edge a hybrid technique is proposed based on pixel neighbors pattern analysis PNPA. In the technique Canny operator for initial edge detection, PNPA operation for edge enhancement are performed for remote sensing satellite image successively. The visual and subjective evaluation shows that the proposed PNPA operation can effectively eliminate the influence of edge discontinuity which occurred due to noise and blurr in original captured image, as comparing to existing edge segmenting processes.

施肥与割胶制度的关系

世界热带农业信息 1980年第2期 7-9页

作者： abdul wahab 邓超雄

用2,4—滴、2,4,5—涕和乙烯利刺激割胶,能获得较高的产量,但养分损耗也有所增加,这是胶树排胶量较大造成的。氮、钾和镁的损耗尤多。用乙烯利刺激比用2,4—滴和2,4,5—涕增产多,因此养分的流失也就更多(表1)。

A fishers’women-led Participatory Action Research(PAR)was conducted in 30 homestead ponds to assess the potential for polyculture of Tilapia(Oreochromis niloticus)and major carps Rohu(Labeo rohita)and Catla(Catla catla)in two coastal fishing villages of *** treatments,namely T1(Tilapia 200 fish per decimal;1 decimal=40 m^2),T2(Tilapia 200+Rohu 32+Catla 8 fish per decimal)and T3(Tilapia 200+Rohu 8+Catla 32 fish per decimal),each with 5 replicates,were tried in Hossainpur and Anipara *** commercial Mega-feed was applied to the ponds twice daily at an initial rate of 10%body weight(bw)/day of Tilapia down to 4%bw/day throughout the culture *** water quality parameters of ponds including transparency,salinity and dissolved oxygen significantly varied among treatments except temperature and pH and remained within optimum range for carp polyculture except *** survival rate,harvesting weight and yield of Tilapia were significantly highest in T1(85.63±05%,258.59±18.76 g&11073±805 kg/ha,respectively)in Anipara and lowest in T3(75.63±0.37%,136.97±10.63 g&5180±406 kg/ha,respectively)in *** gross fish production was the significantly highest in T1(11354±806 kg/ha)of Anipara and lowest in T1(6325±227 kg/ha)of ***,the highest net return(866,627±84874 BDT/ha)was found in T1 of Anipara and lowest in T3(279,389±46104 BDT/ha)of Hossainpur with a significantly higher benefit-cost ratio(BCR)obtained in T1(3.26±0.20)for Tilapia and lower in T3(1.58±0.10)for polyculture Tilapia and carp of ***,it may be concluded that Tilapia production in small homestead coastal ponds has a higher potential than its mix with carps in polyculture for generating food and supplemental income opportunity for coastal fishers’women in Bangladesh.

Cairo＇s Slums： A Ticking Time Bomb

引用

Journal of Civil Engineering and Architecture 2014年第8期8卷 989-1008页

作者： abdul-wahab El-Kadi College of Engineering and Technology Arab Academy for Science and Technology and Maritime Transport Cairo 11311 Egypt

Despite being one of the symbols of civilization throughout human history, Greater Cairo has many slum areas, hosting a population of three million people living in deteriorating conditions and lacking the basic human necessities. These slums represent a fertile environment for diseases caused by pollution in all its forms and are subject to crimes, rape and theft. There is a huge difference in the state of conditions when comparing the formally planned areas to the informally planned ones. People living in the formally planned settlements, like Nasr City, and in informal ones, like Ezbet El-Haggana, are similar to the kings and queens and slaves of legends. This paper tries to find solutions to the problem of slums and random areas.
