Authentication watermarking approaches can be classified into two kinds: fragile and semi-fragile. In contrast to the latter one, fragile watermarking does not tolerate modifications of any single bit of the watermarked data. Since the transmission of digital data often requires lossy compression, an authentication system should accept non-malicious modifications such as JPEG compression. Semi-...

Attention problems are among the most impairing features associated with fragile X syndrome (FXS). However, few studies have examined behavioral development of inhibitory control in very young children with FXS. We examined attentional control in 3-6 year boys with FXS using both an experimental inhibitory control paradigm and parent-report of attention problems. Study 1 examined attentional co...

This paper presents an LMI based design method for static output feedback controllers with a guaranteed H2 performance. The method can be applied to a class of continuous-time linear systems with either rational or polynomial parameter dependence, provided that the parameters and their rate of variation are bounded by a given polytope. Stability as well as a H2 performance bound are guaranteed ...

With the tremendous growth and use of digital cameras and video devices, the need to verify the collected digital content for law enforcement applications such as crime scene investigations and traffic violations, becomes paramount if they are to be used as evidence in courts. Semi-fragile watermarking has become increasingly important within the past few years as it can be used to verify the c...

There is evidence which demonstrates that a subset of males with a premutation CGG repeat expansion (between 55 and 200 repeats) of the fragile X mental retardation 1 gene exhibit subtle deficits of executive function that progressively deteriorate with increasing age and CGG repeat length. However, it remains unclear whether similar deficits, which may indicate the onset of more severe degener...

Many European countries still provide their citizens with social insurance programs of unprecedented generosity. A cultural critique of the welfare state contends that generous social insurance has detrimental effects on work norms. This paper revisits the model of endogenous work ethic developed by Lindbeck and Nyberg (2006) and explores survey evidence on the relationship between social spend...

In this paper, a semi-fragile watermarking technique operating in the wavelet domain is proposed. A hierarchy of the image blocks is constructed and the image features are extracted such that relationships among image blocks are established in order to enhance the security and robustness of the system. With such a hierarchy, the image can be authenticated at different levels of resolution, henc...

Many manipulation systems using air flow have been proposed for object handling in a non-prehensile way and without solid-to-solid contact. Potential applications include high-speed transport of fragile and clean products and high-resolution positioning of wafers. This paper discusses a comprehensive survey of state-of-the art pneumatic manipulation from the macro scale to the micro scale. The ...

In a recent work by the authors, an H 1 based ow controller was designed for explicit rate based congestion control in high speed networks. Time delay uncertainties were taken into account when the controller was designed. This paper studies robustness margins, e.g. largest allowable time delay, as functions of a weighting parameter used in the deenition of the H 1 optimization problem. Another...

A fractional order PID controller is designed to stabilize fractional delay systems with commensurate orders and multiple commensurate delays, where the time delays in the system may belong to several distinct intervals. Moreover, the controller parameters should belong to given intervals. In order to stabilize the system, the D-subdivision method is employed to choose the stabilizing set of th...
