Slums in Egypt – as in many developing countries – are considered as one of the most important problems in Egypt. There are about 1,100 slum areas hosting about 16 million inhabitants. Slums in Egypt vary considerably in their characteristics which make prioritization and intervention policy a debatable issue.

The Kingdom of Saudi Arabia (KSA) Ministry of Interior (MOI) has initiated a major development program for its Border Guard (BG) to develop the BG’s organization into a 21st century security force capable of delivering comprehensive border protection [KSA MOI 2007]. Such a sustainable approach requires a comprehensive modernization and integration of command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR), supporting…

The malaria endemic problem is major concern in the 14 States and Union Territories. The malaria endemic has been severe threaten to the people of highland areas of north eastern states and the eight other states in India..

Two Radarsat-2 images acquired in fine quad-polarized mode were chosen for this study. The images were collected in leaf-on and leaf-off seasons. The experimental results demonstrated that the neighboring information provides valuable information for the classification of Polarimetric SAR data. The classification results showed that the proposed methodimproves classification accuracy significantly over the baseline methods.

Landslide occurrence is one of the natural disasters which causes great damages annually all over the world and that is the reason, prediction and monitoring of landslides is of great concern. Landslide susceptibility determination relies largely on information which is provided by the landslide inventory maps. Therefore, precise land displacement determination can be regarded as one of the preliminary steps towards a more reliable landslide prediction.

A comparison between the seismicity and active faulting density maps indiactes that a good spatial correlation can be observed between these two parameters. It probably means that active faults are the main seismogenic sources responsible for generating earthqukes in this region. The good consistency observed between the seismogenic zoning map presented in this research and the results of the previous works indicates that the spatial analysis techniques can reliably be used for seismic hazard regionalization and identifying seismogenic hazardous zones in seismically active regions.

The study areas are situated in the Arabian Gulf. -It is a shallow sea with its long axis oriented in NW-SE direction, and its average water depth is about 36m. The Evaporation and wind are the main driving forces for water circulation in the Arabian Gulf. Evaporation is stronger in winter due to high wind speed, than summer when the water surface temperature is higher. The overall circulation in the inner Arabian Gulf is cyclonic…

The present study aims at developing a generic automated methodology for addressing Multi-Objective Multi- Criteria Decision-Making problems. Scientific approach which make use of analytical modeling techniques are essential to suggest suitable changes in land use and to generate action plan for an area for land and water resource development. This problem can be cast into a multi-objective multicriteria decision-making problem…

Beneath our feet in the UK lies a vast labyrinth of millions of kilometres of buried pipes and cables, delivering key products and services essential to our social and economic well-being. These networks of buried assets need repair and maintenance, and the growing demands of the UK economy mean that in years to come the networks will continue to grow significantly, as will the amount of traffic on the streets under which many of these assets lie.
There are now more companies involved in digging holes across the UK than ever before. Latest estimates put this figure at around 4 million holes dug by utility companies annually, and this excludes any excavations made as part of construction projects and works away from the street. Every time a hole is dug it impacts on traffic and the local environment. Often, holes turn out to be ‘dry’ – inaccurate information means that assets thought to be there cannot be found.
