This paper describes a novel packet loss concealment (PLC) algorithm for Bluetooth CVSD codec by updating decoder states efficiently through state-copying. In the proposed method, the decoder states are stored in buffers and then selected based on the estimated pitch period of the decoded signal. The selected states are used to reset the decoder states when the packet is lost or corrupted. Obje...

OBJECTIVES To compare how allocation concealment is described in publications of randomised clinical trials and corresponding protocols, and to estimate how often trial publications with unclear allocation concealment have adequate concealment according to the protocol. DESIGN Cohort study of 102 sets of trial protocols and corresponding publications. SETTING Protocols of randomised trials ...

We studied antegrade concealed conduction of atrial extrastimuli (A2) that blocked in the atrioventricular (AV) node in eight subjects, using a third extrastimulus (A3), coupled at decreasing coupling intervals to A2. Three A1-A2 intervals were tested in each subject: late (just shorter than AV nodal effective refractory period), intermediate, and early (just longer than atrial functional refra...

Abstract In order to assure the concealment by cryptographic protocols, it is an effective measure prove in a formal logical system. contemporary context of protocol, has be proved using probability theory. There are several concepts One them Bayesian concealment. This study proposes system secret sharing scheme.

Understanding self-concealment, the tendency to actively conceal distressing personal information from others, may be important in developing effective ways to help individuals with suicidal ideation. No published study has yet assessed the relation between self-concealment and suicidal behaviors. Additionally, most self-concealment research has been conducted solely with younger adults. The re...

Although concealment in relationships is commonplace, little is known about its implications for the target of concealment. Two large-scale studies among adolescents and their parents tested the central hypothesis that parents’ perception of child concealment predicts poorer parenting behaviors toward their child. Further, we investigated whether actual child concealment adds to the prediction ...

Video transport over error-prone channels may result in loss or erroneous decoding of the video data. Error concealment is an effective mechanism to reconstruct the video data. In this paper, we review error-concealment methods and introduce a new framework, which we refer to as second-generation error concealment. All the error-concealment methods reconstruct the lost video data by making use ...
