The problem of compensation of infinite-dimensional actuator or sensor dynamics of more complex type than pure delay was solved recently using the backstepping method for PDEs. In this paper we construct an explicit feedback law for a multi-input LTI system which compensates the wave PDE dynamics in its input and stabilizes the overall system. Our design is based on a novel infinite-dimensional...

SUMMARY This paper proposes a robust state observer for multi-input multi-output LTI systems. Unknown inputs of polynomial form and high-frequency measurement noises are considered in the system model. The unknown inputs and the noises are not in the same form. Multiple integra-tions of both the observer error signal and the measurement output are used for the observer design. The existence con...

Mohandas Karamchand Gandhi had a knack for identifying the simplest of things which would have an impact on the masses. He knew that food and clothing mattered the most to the impoverished millions in India. The Dandi March was a clarion call to defy the salt laws. The Swadeshi enterprise with khadi as the dominant theme showed Gandhi's immense skill at effective mobilization. This paper would ...

P olicies aimed at reducing inequalities in the healthcare domain in France tend to be focused on access to healthcare, either by extending Statutory Health Insurance coverage (Universal Health Insurance Coverage (CMU) known as "basic" coverage, and State Medical Aid (AME), or by extending complementary health insurance coverage (complementary CMU and financial assistance for the acquisition of...

The objective of the present paper is to analyse syntactic ambiguity of prepositional groups (Pg’s) within the background of dependency oriented Functional Generative Description (FGD). Several basic types of Pg-ambiguity are presented and the possibilities of searching for their occurrences in the Prague Dependency Tree Bank (PDT) is illustrated. Criteria for automatic Pg-ambiguity detection a...

In this paper, information about the steganographic methods and tools that are used to hide important data in digital media are presented. At the same time, different aspects of these tools such as used methods, types of hidden data and cover media are examined.
