PalanisamyProblem statement: To meet the demand for high speed transmission of image in efficient image storage and remote medical treatment, the efficient image compression is essential. The contourlet transform along with wavelet theory has great potential in medical image compression. Approach: The significant portion of the medical image applied with Fuzzy C-means based contourlet transform. DWT applied to the rest … …Journal of Computer Science, Vol. 7, Issue 9 · 25 Jul 2011 · 7,082 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApplying Packet Generator for Secure Network EnvironmentMohammed N. Abdul Wahid, Zuriati Ahmed ZulkarnainProblem statement: Viruses and hacker attacks typically generate a recognizable pattern or “signature” of packets. Most of Network Traffic Analyzer can identify these packets and alert the administrator to their presence on the network via email or page. Approach: Most traffics analyzers let you set alarms to be triggered when a particular pattern is seen. Results: Some network traffic analyzers … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,264 accessesView PDFCite

AhmadProblem statement: Voltage disturbances are the most common power quality problem due to the increased use of a large numbers of sophisticated electronic equipment in industrial distribution system. The voltage disturbances such as voltage sags, swells, harmonics, unbalance and flickers. High quality in the power supply is needed, since failures due to such disturbances usually have a high impact on … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,376 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordWellbore Surveying While Drilling Based on Kalman FilteringMahmoud ElGizawy, Aboelmagd Noureldin, Jacques Georgy et al.Problem statement: Oil and gas are global fuels obtained primarily from drilling wells in underground terrestrial reservoirs. Vertical drilling is preferred because of its simplicity and therefore low cost, but subsurface targets can often be procured only by directing the wellbore along predefined non-vertical trajectories. For instance, directional drilling must be employed to reach locations inaccessible to the drilling rig, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,577 accessesView PDFCite
