The wavelet transform-domain least-mean square (WTDLMS) algorithm uses the self-orthogonalizing technique to improve the convergence performance of LMS. In WTDLMS algorithm, the trade-off between the steady-state error and the convergence rate is obtained by the fixed step-size. In this paper, the WTDLMS adaptive algorithm with variable step-size (VSS) is established. The step-size in each subf...

This particular research was conducted under the light of Martha Rapp Haggard’s vocabulary approach known as Vocabulary Self-Collection Strategy (VSS). The aim this to enhance active usage in learners with help VSS. Moreover, current study based on role VSS an English language learning classroom at intermediate level. A diagnostic pre-test ‘vocabulary self-collection group’ and ‘controlled grou...

Abstract In a virtualized computer system with shared resources, consolidated virtual services (VSs) fiercely compete each other to obtain the required capacity of and this causes significant system's performance degradation. The input output (I/O)‐bound applications running inside their own VS is mainly determined by total time schedule every read/write request, plus actual needed device drive...

Title of dissertation: BROADCAST AND VERIFIABLE SECRET SHARING: NEW SECURITY MODELS AND ROUND-OPTIMAL CONSTRUCTIONS Ranjit Kumaresan, Doctor of Philosophy, 2012 Dissertation directed by: Professor Jonathan Katz Department of Computer Science Broadcast and verifiable secret sharing (VSS) are central building blocks for secure multi-party computation. These protocols are required to be resilient ...

Verifiable secret sharing (VSS) schemes [1–3] rely on the assumption that parties can not reliably fabricate false secret shares which pass the verification process. Here, we show that, for certain VSS implementations that use verification commitments bounded to a finite field, this assumption is incorrect. Let there be n shares of a secret and a threshold of t secret shares required to get the...

In many pairing-based cryptosystems, the secret keys are elements of bilinear groups. For safeguarding such secret keys or decrypting or signing in a threshold manner, Verifiable Secret Sharing (VSS) in bilinear groups is required. In this paper, we show a method of verifiably sharing a random secret in a bilinear group. Our method is simple and practical. It can be regarded as a generalisation...

The pharmacokinetics of nalbuphine 20 mg i.v. were studied in 10 patients undergoing lower abdominal or body surface surgery. Blood sampling was carried out for 600 min after injection and drug concentrations were measured by HPLC using electrochemical detection. Disposition was best described as a triexponential function, with a mean elimination half-life of 135.5 min. Mean residence time, cle...

The idea of variable step-size was introduced into the Hybrid Affine Projection Algorithm (H-APA) and we propose two step size algorithms based on H-APA, which are called Variable Step-Size (VSS-H-APA) Modified (MVSS-H-APA). These variable-step aim to further improve robust performance convergence speed H-APA under non-Gaussian noise. This allows for faster while maintaining stability. MVSS-H-A...
