Block matching algorithms for motion estimation using modified Cross-Diamond-Hexagonal search / Abd Razak Mahmud
Published 2008“…Block-matching motion estimation is the most important part in today's video coding techniques and standard, such as 1S0/IEC MPEG-1, 2, 4, ITU-T H.261, H.263, and the emerging H.264. Each of the video frames is divided into macroblocks. The computational of the current pixel in current frame is compared to the previous decoded frame as a reference. …”

Modified synchronous reference frame based shunt active power filter with fuzzy logic control pulse width modulation inverter
Published 2017“…In order to mitigate this power quality issue, the shunt active power filter (SAPF) has been widely applied and it is proven to be the best solution to current harmonics. This paper evaluates the performance of the modified synchronous reference frame extraction (MSRF) algorithm with fuzzy logic controller (FLC) based current control pulse width modulation (PWM) inverter of three-phase three-wire SAPF to mitigate current harmonics. …”

A new security framework to prevent denial of service and replay attacks for IEEE 802.11 wireless networks
Published 2011“…The ACF-non-cryptographic countermeasure proposes a lightweight security model without involving cryptographic algorithms. The ACF-cryptographic countermeasure proposes four distinct models; two models are based on SHA1 and SHA2, and another two models are based on modified SHA1 and SHA2. …”

Development of an integrated scheduling model for handling equipment in automated port container terminals
Published 2014“…In addition, results proved that the modified meta-heuristic algorithm is able to find near optimal solutions and on average, the solutions found by the GA algorithm are only 0.2% worse than the optimal solutions and in the worst case in the test cases this difference is 2.3% which is acceptable. …”
