GreenHouse Gasses’ (GHG) emission control is the greatest environmental challenge facing the world. The energy sector accounts for the highest percentage of environmental pollution. Emissions from internal combustion power generators are high and these emissions are responsible for the fast depletion of the ozone layer. Though there are other measures put in place to control the emission from p...

Like many developed countries, energy efficiency and environment impact are the most important process in the development of power generation policy in India. A high ambient temperature reduces the air density and makes inlet air cooling (IAC) and steam injection gas turbine (STIG) attractive power augmentation method for existing regenerative gas turbine. With a high back work ratio and a high...

A seismic risk analysis addressed to earthquake emergency management and protection strategies planning, requires territorial scale evaluation; to this aim a macroseismic method for the vulnerability assessment of built-up area is presented. The method is derived, in a conceptually rigorous way, by the use of Probability and of Fuzzy Set Theory, considering Macroseismic Scale definitions. Damag...

Reverse engineering has many important applications in computer security, one of which is retrofitting software for safety and security hardening when source code is not available. By surveying available commercial and academic reverse engineering tools, we surprisingly found that no existing tool is able to disassemble executable binaries into assembly code that can be correctly assembled back...

Scientific databases (ScDBs) are used to archive and retrieve data describing objects of scientific inquiry. Since these ScDBs must provide continuous and efficient access to large communities of scientists, they are often developed with reliable commercial relational database management systems (DBMSs) or file systems. However, relational DBMSs and flat files do not provide constructs for repr...

due to simple operation and no needs for expensive infrastructure construction to convey water from a source to farm lands, groundwater becomes the most important sources of agricultural water supply in iran. however, the contamination of aquifers is a major concern in many countries, specifically in areas without effective groundwater protection and management. therefore, groundwater vulnerabi...

Conventional power systems are developing into cyber-physical power systems (CPPS) with wide applications of communication, computer and control technologies. However, multiple practical cases show that the failure of cyber layers is a major factor leading to blackouts. Therefore, it is necessary to discuss the cascading failure process considering cyber layer failures and analyze the vulnerabi...

In recent years, even if Fiber Reinforced Polymer (FRP) composites have been widely used for strengthening of civil buildings, a new generation of materials has been studied and proposed for historical masonry construction. These buildings, mainly made of stone work, are common in many areas of Europe and Asia and recent earthquakes has been the cause of many catastrophic failures. The brittlen...
