The aim of this paper is to study the regional observer concept through the consideration of sensors. For a class of distributed diffusion systems, we propose an approach derived from the Luenberger observer type as introduced by Gressang and Lamont [1]. Furthermore, we show that the structures of sensors allow the existence of regional observer and we give a sufficient condition for each regional observer. We also show that, there exists a dynamical system for diffusion systems is not observer in the usual sense, but it may be regional observer.

The perception-related origins of physical measures and standards are considered within the framework of the general observer theory. The impact of observer characteristics on the development of observer-centric physics, physical concepts and metrics are analyzed. A preliminary theoretical approach is suggested for the construction of a general observer theory and formulation of its relationship to observer-centered physical concepts and theories. The approach makes it possible to construct a theory of the observer, intrinsic in any theory of physics.

The numerical value of any measurement outcome is mapped by any function of the observer’s choosing onto integers and fractions of a denomination of the observer’s choosing. Measurement outcomes that are closely related in the mind of the observer result in symmetrically related integers and fractions. From the totality of measurements, the observer apprehends a self-consistent reality ruled by theories believed by the observer.

In this note we introduce and investigate the concepts of dual entwining structures and dual entwined modules. This generalizes the concepts of dual Doi-Koppinen structures and dual Doi-Koppinen modules introduced (in the infinite case over rings) by the author is his dissertation.

The analysis of the most important concepts of social systems theory of NiklasLuhmann Observer. The authors explore the phenomenon of the observer in the society, its functional properties; describe the interaction model of the system, and an observer of the world. The authors conclude that the observer is determined Luhmann as that (who) makes a difference. This definition is correct, but it flattens too understanding. The authors therefore consider it necessary to explain the observer through its functional properties. The main function of the observer the product of the operation of distinction and designations. This function can be deduced place an observer in the system: the observer is the custodian of the memory of all the operations of the system. Observer participates in the evolution of the system and in the formation of the new systems. Observer always exists the potential to self-referential systems, because they produce their own reasons. In systems that are not self-referential, can only be an external observer. The notion of an observer is installed between the concept of «system» and «distinction».

The CADO reference frame is defined for an observer who accelerates in any manner whatsoever. Specifically, the observer's acceleration a(t), where t is any instant in the observer's life, can be whatever the accelerating observer wants it to be, without restriction.

Image quality can be objectively defined according to how well an observer can perform a task of practical interest given the image. We review a practical model observer for the signal-detection task. The ideal observer for this task is a function of the image probability distributions, which are multidimensional and complicated. This observer is often too difficult to derive or estimate. An alternative to the ideal observer is the ideal linear observer, which can still be unmanageable. Our alternative is the ideal linear observer constrained to a small set of channels: the channelized-Hotelling observer.

ABSTRACT With dual trading, brokers trade both for their customers and for their own account. We study dual trading and find that customers who are less likely to be informed have higher expected profits with dual trading while customers who are more likely to be informed have higher expected profits without dual trading. We also examine the effects of frontrunning. We test the major empirical implications of our model. Consistent with the model, dual traders earn higher profits than non‐dual traders, and customers of dual‐trading brokers do better than customers of non‐dual‐trading brokers.
