Altering Split Decisions of Coding Units for Message Embedding in HEVC
(Springer, 2017-05)This paper proposes a novel message embedding solution based on modifying the split decisions of HEVC videos. The encoder starts by computing a mapping between the split decisions of a Coding Unit (CU) and its features ... -
Analyzing Sensitivity Measures Using Moment-Matching Technique
(Elsevier, 2017-03)Sensitivity indices are used to rank the importance of input design variables or components by estimating the degree of uncertainty of output variable influenced by the uncertainty generated from input variables or components. ... -
Capacity of Fox's H-function Fading Channel with Adaptive Transmission
(Institution of Engineering and Technology, 2016)Novel closed-form exact expressions for the capacity of the recently-introduced Fox's H-function fading channel are derived. The expressions are obtained assuming different types of adaptive transmission strategies, namely, ... -
Closed-form Exact and Asymptotic Expressions for the Symbol Error Rate and Channel Capacity of the H-function Fading Channel
(IEEE Vehicular Technology Society, 2016-04)In this paper, we derive closed-form exact and asymptotic expressions for the symbol error rate (SER) as well as channel capacity when communicating over the Fox's H-function fading channel. The SER expressions are obtained ... -
Continuous Arabic Sign Language Recognition in User Dependent Mode
(Scientific Research, 2010)Arabic Sign Language recognition is an emerging field of research. Previous attempts at automatic visionbased recognition of Arabic Sign Language mainly focused on finger spelling and recognizing isolated gestures. In this ... -
Corrosion Behavior of Common Metals in Eutectic Ionic Liquids
(International Journal of ELECTROCHEMICAL SCIENCE, 2019)The corrosion behavior of six choline chloride-based eutectic solvents namely, ChCl-Ur, ChCl-EG, ChCl-Gl, ChCl-MA, ChCl-Ph and ChCl-TG towards copper, mild steel and stainless steel 316 have been investigated. The effect ... -
Critical resolved shear stress for slip and twin nucleation in single crystalline FeNiCoCrMn high entropy alloy
(Elsevier, 2017)High entropy alloys is an emerging class of materials with superior mechanical properties down to cryogenic temperatures. At 77K, and unlike traditional metallic alloys, an increase in strength, strain hardening rate, and ... -
Data Embedding in HEVC Video by Modifying the Partitioning of Coding Units
(Institution of Engineering and Technology, 2019-07)This paper proposes a data embedding solution in HEVC videos by modifying the partitioning of Coding Units (CUs). The partitions of a CU are first represented as a sequence of binary flags. The flags pertaining to 16x16 ... -
Data Hiding in MPEG Video Files Using Multivariate Regression and Flexible Macroblock Ordering
(IEEE, 2012)This paper proposes two data hiding approaches using compressed MPEG video. The first approach hides message bits by modulating the quantization scale of a constant bitrate video. A payload of one message bit per macroblock ... -
Decision-level fusion for single-view gait recognition with various carrying and clothing conditions
(Elsevier, 2017)Gait Recognition is one of the latest and attractive biometric techniques, due to its potential in identification of individuals at a distance, unobtrusively and even using low resolution images. In this paper we focus on ... -
Detection of frame deletion for digital video forensics
(Elsevier, 2013-12)The abundance of digital video forms a potential piece of evidence in courtrooms. Augmenting subjective assessment of digital video evidence by an automated objective assessment helps increase the accuracy of deciding ... -
Dynamics of a four-bar mechanism with clearance and springs - Modeling and experimental analysis
(Korean Society of Mechanical Engineers and Springer, 2017)This paper presents a study of the dynamic behavior of a planar four-bar mechanism with clearance. A spring is added to improve the dynamic response of the mechanism with clearance. Simulations and experimental tests are ... -
Economic Allocation of Reliability Growth Testing Using Weibull Distributions
(Elsevier, 2016-08)Reliability growth testing (RGT) has been widely used for assessing the reliability of complex systems in many industries such as automotive, aerospace, and oil and gas industry. The traditional common and practiced approach ... -
The effect of pegylation and targeting moieties on the ultrasound-mediated drug release from liposomes
(ACS Publications, 2019)The use of targeted liposomes encapsulating chemotherapy drugs enhances the specific targeting of cancer cells, thus, reducing the side effects of these agents and providing a more patient-friendly treatment. Targeted ... -
Emotion Recognition Based on Fusion of Local Cortical Activations and Dynamic Functional Networks Connectivity: An EEG Study
(IEEE Xplore Digital Library, 2019)In this paper, we present a method to improve emotion recognition based on the fusion of local cortical activations and dynamic functional network patterns. We estimate the cortical activations using power spectral density ... -

Evaluation of the contribution of flexural CFRP plates in shear strengthening RC beams
(Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures, 2015)Strengthening of RC beams for shear has been typically done by externally attaching strips of steel plates or carbon-fiber reinforced polymer (CFRP) sheets or plates on the sides of the beams. However, sides of beams ... -
