Engineered surface strategies to manage dental implant‐related infections
Periodontology 2000, EarlyView.Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Realization of DVCCTA Based Versatile Modulator
Active and Passive Electronic Components, Volume 2014, Issue 1, 2014., 2014 A Differential Voltage Current Conveyor Transconductance Amplifier (DVCCTA) based versatile modulator is proposed which can work as an amplitude modulator, frequency modulator, delta modulator, and sigma delta modulator. The modulator operational scheme uses pulse generator as a core and its output is used as carrier signal.

An optimized transform and quantization scheme for HEVC intra lossless coding
Engineering Reports, Volume 6, Issue 11, November 2024.In this article, we propose an Intra lossless coding scheme based on transformation and quantization for High Efficiency Video Coding (HEVC). The initial residual block is divided into two parts: the coefficient block and the error block. The proposed mode is combined with the transform bypass mode to achieve better coding efficiency at transform units

Analysis and Design of Network‐Based Control Systems with Binary Modulation
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 Network‐based control systems have been emerging technologies in control and computer communication fields over the past decade. This paper focuses on the analysis and design of network‐based control systems with binary modulation. First, it is shown that different modulations can result in different delays which are inevitable in network‐based control

Advances in Multimedia, Volume 2012, Issue 1, 2012., 2012 We consider the problem of optimal H.264 scalable video scheduling, with an objective of maximizing the end‐user video quality while ensuring fairness in 3G/4G broadband wireless networks and video sensor networks. We propose a novel framework to characterize the video quality‐based utility of the H.264 temporal and quality scalable video layers ...

Hybrid Color Image Compression based DPCM and Slant Transform
مجلة النهرين للعلوم الهندسية, 2010 Nowadays, still images are used everywhere in the digital world. Images take lot of computer space, in many practical situations, all original images cannot be stored, and a compression must be used.

Iraqi Journal of Computers, Communications, Control and Systems Engineering, 2008 In this paper the performance of speech compression system using discrete wavelet transform (DWT) is investigated .Two methods are used for this purpose ;in the first only discrete wavelet transform is used .In the second method linear predictive coding (LPC) in wavelet transform is used . Both methods are used differential pulse code modulation (DPCM)
