Spread spectrum audio watermarking (SSW) is one of the most powerful techniques for secure audio watermarking. SSW hides information by spreading the spectrum. The hidden information is called the ‘watermark’ and is added to a host signal, making the latter a watermarked signal. The spreading of the spectrum is carried out by using a pseudo-noise (PN) sequence. In conventional SSW approaches, t...

High-quality surface reconstruction of scanned physical objects using CAD or polygonal modeling packages represents a time consuming manual process. So far none of the fully automatic approaches to reconstruct free-from surfaces have lead to satisfying results that can compete with manually created objects based on traditional modeling techniques and most importantly an artist’s experience. In ...

The application of fuzzy logic (FL) supervisors (FLS) for on-line nonlinear auto-tuning of the basic FL controllers (FLCs) gains popularity as a simple adaptive technique for improvement of the performance of control systems for plants with nonlinearities, inertia, time-delay, model uncertainty and variable parameters. Various approaches for the FLS design are developed for different types of F...

The job of automatic frequency regulation is achieved by governing systems of individual turbine generators and Automatic Generation Control (AGC) or Load frequency control (LFC) system of the hydro power plant. This seminar report addresses a comprehensive literature survey on load frequency control in hydro power plant. The report is aimed to present the various control and structural schemes...

abstract background: supervisors should have certain characteristics and adequate preparation for their roles. yet, there are no well‑educated experts knowing about the supervisor’s role and responsibilities and how to train them. so, this research was conducted with the purpose of finding the factors affecting nursing supervisor training. materials and methods: this research is an inductive co...

This study examines how the combined effects of work environmental factors and leadership behaviours lead to presence (or absence) industrial employees job performance by applying fuzzy-set qualitative comparative analysis (fsQCA). A sample composed supervisor-subordinate dyads was used test propositions this study. The results show that most important variables are transformational social supp...
