The Internet and web applications are playing very important role in our today’s modern day life. Most of the web applications use the database as a back end to store critical information. SQL injection attacks represent a serious threat to any database-driven site. The methods behind an attack are easy to learn and the damage caused can range from considerable to complete system compromise. De...
one of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. several parameters should be optimized in a fluid injection process. the usual optimizing methods evaluate several scenarios to find the best solution. since it is required to run the reservoir simulator hundreds of times, the process...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
In this paper we describe a preliminary, in-progress, research of fashion\trends in HCI. First, we present the motivation for this research, as this topic has not been methodically researched despite the accelerating pace and growing influence of fashion\trends in modern life. In order to provide appropriate theoretical background, we define and explain the fashion and trend phenomena using res...
HCI evaluation methods tend to be proposed and used to verify the interactive qualities of specific systems and design strategies. A discussion about the scientific merits of such methods to advance knowledge in HCI as a field is very rare, although much needed. This paper shows that, under certain conditions, inspection methods can be safely used in scientific research in HCI and extend their ...
We refine our approach for hot-carrier degradation modeling based on a thorough evaluation of the carrier energy distribution by means of a full-band Monte–Carlo simulator. The model is extended to describe the linear current degradation over a wide range of operation conditions. For this purpose we employ two types of interface states, either created by singleor by multiple-electron processes....
in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...
pressurized injection operation means the pressurized injection of a liquid or solution into pore of a mass of soil or stone and/ or cavity between them and built structures. the injected mortar mustconstitute a soil and/ or jel- like matter inside the cavites, and/ or the operations of the injection must cause sedimentation of the solid matter suspending in these cavites. the primary purpose o...
