this paper addresses adaptive observer design problem for joint estimation of the states and unknown parameters for a class of nonlinear systems which satisfying one-sided lipschitz and quadratic inner bounded conditions. it’s shown that the stability of the proposed observer is related to finding solutions to a quadratic inequality consists of state and parameter errors. a coordinate transform...

PurposeThe objective assessment of image quality (IQ) has been advocated for the analysis and optimization medical imaging systems. One method computing such IQ metrics is through a numerical observer. The Hotelling observer (HO) optimal linear observer, but conventional methods obtaining HO can become intractable due to large sizes or insufficient data. Channelized are sometimes employed in ci...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

Electronic contracts are a means of representing agreed responsibilities and expected behaviour of autonomous agents acting on behalf of businesses. They can be used to regulate behaviour by providing negative consequences, penalties, where the responsibilities and expectations are not met, the contract is violated. However, long-term business relationships require some flexibility in the face ...

in this paper, an observer based fuzzy adaptive controller (fac) is designed fora class of large scale systems with non-canonical non-affine nonlinear subsystems. it isassumed that functions of the subsystems and the interactions among subsystems areunknown. by constructing a new class of state observer for each follower, the proposedconsensus control method solves the problem of unmeasured sta...

This paper introduces a robust task-space control scheme for a robotic system with an adaptive observer. The proposed approach does not require the availability of the system states and an adaptive observer is developed to estimate the state variables. These estimated states are then used in the control scheme. First, the dynamic model of a robot is derived. Next, an observer-based robust contr...

BACKGROUND Two cases of sudden unexpected deaths in patients with multiple sclerosis were investigated by the Office of The Chief Forensic Pathologist. METHOD Case studies. RESULTS Marked similarities of the deaths, including circumstances, scene examination, and autopsy findings including a complete drug screen were recorded. CONCLUSIONS Exposure to high ambient temperature may pose a da...

Using Schachter's theory of emotion as a starting point, two predictions regarding the interaction of alcohol consumed in social and solitary situations were tested experimentally. It was predicted that the cognitive circumstances of social drinking would promote an affective response to alcohol, whereas the same objective level of intoxication would be responded to as physical symptoms among s...
