An inhomogeneity correction algorithm for irregular fields of high-energy photon beams based on Clarkson integration and the 3D beam subtraction method
(2006)
A number of treatment-planning systems still use conventional correction methods for body inhomogeneities. Most of these methods (power law method, tissue-air ratio (TAR), etc.) consider only on-axis points, rectangular ...
Power reduction in an H.264 encoder through algorithmic and logic transformations
(2006)
The H.264 video coding standard can achieve considerably higher coding efficiency than previous video coding standards. The keys to this high coding efficiency are the two prediction modes (Intra & Inter) provided by H.264. ...
Online resources for miRNA analysis
(2013)
Objective: This review aims to provide a brief introduction to each major category of available tools and algorithms for microRNA (miRNA) research, as well as to present some of the most widely used or promising representative ...
Ultrasonic monitoring of bone fracture healing
(2008)
Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an ...
Tracking Particle Swarm Optimizers: An adaptive approach through multinomial distribution tracking with exponential forgetting
(2012)
An active research direction in Particle Swarm Optimization (PSO) is the integration of PSO variants in adaptive, or self-adaptive schemes, in an attempt to aggregate their characteristics and their search dynamics. In ...
Distributed dynamic scheduling for end-to-end rate guarantees in wireless ad hoc networks
(2005)
We present a framework for the provision of deterministic end-to-end bandwidth guarantees in wireless ad hoc networks. Guided by a set of local feasibility conditions, multi-hop sessions are dynamically offered allocations, ...
Detecting IEEE 802.11 MAC layer misbehavior in ad hoc networks: Robust strategies against individual and colluding attackers
(2007)
Selfish behavior at the Medium Access (MAC) Layer can have devastating side effects on the performance of wireless networks, with effects similar to those of Denial of Service (DoS) attacks. In this paper we consider the ...
An efficient probing mechanism for next generation mobile broadband systems
(2012)
Opportunistic scheduling exploits multiuser diversity for improving the performance of wireless systems. However, it requires instantaneous channel state information (CSI) to be available at the transmitter side. Since ...
Scalable 3D video streaming over P2P networks with playback length changeable chunk segmentation
(2015)
3D video distribution over P2P networks has been thought as a promising way for 3D video entering home. The convergence of scalable 3D video coding and P2P streaming can provide diverse 3D experiences for heterogeneous ...
Low-complexity beamforming techniques for IEEE 802.11n WLANs
(2009)
The impetus of the present study is to describe a downlink beamforming method that increase spectrum efficiency and significantly reduces implementation complexity and power consumption compare to beamforming technique at ...
