Various digital watermarking (WM) techniques for still imaging have been studied in the last severalyears. Recently, many new WM schemes have been proposed for other types of digital multimedia data, such astext, audio and video. This paper presents a brief overview of existing digital video WM. We classify WMtechniques and discuss the properties of video WM. Since each WM applicati...

Water distribution networks face several problems related to leakages, where the pressure control strategy is a common practice for water loss management. Small-scale hydropower schemes, where pumps as turbines replace pressure reducing valves, can be considered an interesting technical solution, which ensures both economic convenience and system flexibility. Due to the water networks’ variable...

A new family of numerical schemes for inhomogeneous parabolic partial differential equations is developed utilizing diagonal Padé schemes combined with positivity–preserving Padé schemes as damping devices. We also develop a split version of the algorithm using partial fraction decomposition to address difficulties with accuracy and computational efficiency in solving and to implement the algor...

The conceptual phase of the aircraft design process demands a parsimonious description of the airframe geometry. While there is no hard and fast upper limit on the affordable number of variables, the so-called ‘curse of dimensionality’ must always be kept in mind: if a thorough, conceptual level search of a one-variable space can be accomplished by the evaluation of n candidate designs, the sam...

Payment for Performance (P4P) schemes by which physicians get a financial reward as long as they reach quality and efficiency targets provided by regulator have become increasingly popular in recent years in OECD countries (1) : in 2012, P4P program for primary care physicians were implemented in about 15 OECD countries. In the US, the number of P4P schemes has grown spectacularly, from 39 in 2...

Abstract The H-1B Visa Reform Act of 2004 dictates an annual allocation 85,000 visas with 20,000 reserved for advanced-degree applicants. We represent the main requirements this legislation as formal axioms and characterize visa rules consistent axioms. Despite precise number reserved, we show that range implementations satisfying these can change by much 14,000 in average year. Of all axioms, ...

The corpus callosum changes structurally throughout life, but most dramatically during childhood and adolescence. Even so, existing studies of callosal development tend to use parcellation schemes that may not capture the complex spatial profile of anatomical changes. Thus, more detailed mapping of callosal growth processes is desirable to create a normative reference. This will help to relate ...
