OFDM and its extension Multi-band OFDM (MB-OFDM) are considered as the modulation schemes for many future communications systems. But these schemes cause high PAPR which should be reduced before power amplification otherwise non-linearities can occur. In this paper Tone Reservation method is used for OFDM PAPR reduction where a corrective signal is added to the original signal to reduce its PAP...

The aim of this study was to identify predictors of a superior functional outcome after corrective osteotomy for paediatric malunited radius and both-bone forearm fractures. We performed a systematic review and meta-analysis of individual participant data, searching databases up to 1 October 2016. Our primary outcome was the gain in pronosupination seen after corrective osteotomy. Individual pa...

To correct the incongruence of document types between the numerator and denominator in the traditional impact factor (IF), we make a corresponding adjustment to its formula and present five corrective IFs: IFTotal/Total, IFTotal/AREL, IFAR/AR, IFAREL/AR, and IFAREL/AREL. Based on a survey of researchers in the fields of ophthalmology and mathematics, we obtained the real impact ranking of sampl...

We present a discriminative model for correcting errors in automatically generated dependency trees. We show that by focusing on “structurally local” errors, we can improve the overall quality of the dependency structure. Defining the task by way of a locality constraint allows us to search over a large set of alternate dependency trees simply by making small perturbations to individual depende...

We present a new hybrid rendering method for interactive walkthroughs in photometrically complex environments. The display process starts from some approximation of the scene rendered at high frame rates using graphics hardware. Additional computation power is used to correct this rendering towards a high quality ray tracing solution during the walkthrough. This is achieved by applying correcti...
