The goal of image watermarking is to hide the specific information into host image and the presence of the watermark cannot be realized by human visual. The watermarking algorithm design should meet the criteria such as the rightful ownership protection, robustness against the image processing attacks and watermark imperceptibility. In this paper an optimal watermarking scheme based on singular...

The minimum mean-square error (MMSE) and minimum error entropy (MEE) are two important criteria in the estimation related problems. The MMSE can be viewed as a robust MEE criterion in the minimax sense, as its minimization is equivalent to minimizing an upper bound (the maximum value) of the error entropy. This note gives a new and more meaningful interpretation on the robustness of MMSE for pr...

Abstract. This work presents the development of a flight control law design structure, based on the H∞ and μ synthesis theory. The design criteria includes usual robustness and performance requirements related to parameters uncertainty in the vicinity of the design point. In addition, the conventional mixed sensitivity design scheme is changed to comply with specific requirements of a flight co...

Protected areas are arguably the most important instrument of biodiversity conservation. To keep them fit under climate change, their management needs to be adapted to address related direct and indirect changes. In our study we focus on the adaptation of conservation management planning, evaluating management plans of 60 protected areas throughout Germany with regard to their climate change-ro...

Traveling Wave Ultrasonic Motor (TWUM) is a compact, precise, and silent actuator generating high torque at low speed without gears. Moreover, the TWUM has a high holding torque without supply, which makes this motor as an attractive solution for holding position of robotic arms. However, their nonlinear dynamics, and the presence of load-dependent dead zones often limit their use. Those issues...

To enable the interoperability of high availability (HA) middleware systems the Service Availability Forum has released a set of open specifications. The benefit of having open specifications is the choice of implementations available from different vendors. When one chooses a product, one of the selection criteria (besides performance) is the robustness of the implementation, as the crashing o...

Timetable construction belongs to the most important optimization problems in public transport. Finding optimal or near-optimal timetables under the subsidiary conditions of minimizing travel times and other criteria is a targeted contribution to the functioning of public transport. In addition to efficiency (given, e.g., by minimal average travel times), a significant feature of a timetable is...

We define a correctness criterion, called robustness against concurrency, for a class of event-driven asynchronous programs that are at the basis of modern UI frameworks in Android, iOS, and Javascript. A program is robust when all possible behaviors admitted by the program under arbitrary procedure and event interleavings are admitted even if asynchronous procedures (respectively, events) are ...

This paper introduces hybrid LU–QR algorithms for solving dense linear systems of the form Ax = b. Throughout a matrix factorization, these algorithms dynamically alternate LU with local pivoting and QR elimination steps based upon some robustness criterion. LU elimination steps can be very efficiently parallelized, and are twice as cheap in terms of floating-point operations, as QR steps. Howe...

To generate a 3D computer model of a free-form object, multiple range images (point clouds) covering its entire surface are acquired from different viewpoints. These views are then aligned in a common coordinate basis by minimizing the distance error between their corresponding points. Establishing correspondences automatically is an inherently challenging problem due to the lack of any type of...
