Loop Snakes: The Generalized Model

Ninth International Conference on Information Visualisation (IV'05), 2006
The topologically adaptable snake model, or simply T-snakes, is a useful tool for automatically identifying multiple segments in an image. According to A. Oliveira et al. (2004), a novel approach for controlling the topology of a T-snake was introduced. That approach focuses on the loops formed by the projected curve which is obtained at every stage of

Nonlinear Models of BPSK Costas Loop

Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014
Rigorous nonlinear analysis of the physical model of Costas loop is very difficult task, so for analysis, simplified mathematical models and numerical simulation are widely used. In the work it is shown that the use of simplified mathematical models, and the application of non rigorous methods of analysis may lead to wrong conclusions concerning the ...

Model-in-the-Loop and Software-in-the-Loop Testing of Closed-Loop Automotive Software with Arttest

2017
In this paper, we present Arttest, a tool for functional testing of block diagrams developed with MATLAB/Simulink. We introduce testing concepts for closed-loop tests of automotive software on model and software level, the integration of the concepts into a signal specification language and correspondent tool support.

Models of dynamic coronal loops

Solar Physics, 2000
This paper reviews the basic ideas underlying one-dimensional fluid dynamic models of coronal loops and presents some of their most recent applications. These models are an important theoretical support to explore the new scenario provided by the data of Yohkoh, SOHO, and TRACE, and are useful to interpret observations, when supplemented by appropriate

Modeling the microbial loop: An estuarine modeler's perspective

Microbial Ecology, 1994
Contemporary models of the microbial loop should be critically evaluated relative to their compartmental structures, flow networks, and treatment of upper ocean physics (vertical and horizontal boundary conditions). The development of new models that include better representation of the autotrophic components and mixotrophy/competitive interactions is ...

Loop parallelization in the polytope model

1993
During the course of the last decade, a mathematical model for the parallelization of FOR-loops has become increasingly popular. In this model, a (perfect) nest of r FOR-loops is represented by a convex polytope in ℤr. The boundaries of each loop specify the extent of the polytope in a distinct dimension.

Closed-loop or open-loop models in identification for control?

1999 European Control Conference (ECC), 1999
In this paper we derive a generic indirect approach of closed-loop identification in order to compare estimated model of the closed-loop transfer function versus reconstructed estimated model of the open-loop plant in terms of asymptotic bias and variance considerations. We show the impact of the sensitivity function on both estimates.

Model-in-the-Loop Testing

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2006
Physical testing is used extensively to characterize mechanical systems. However, in many cases, mathematical models are now available that adequately describe the behaviour of part of the test specimen. Thus, test systems can be conceived which split the specimen into a physical part, and a virtual part, i.e. a real-time computer simulation.

Loop Plant Modeling: An Approach to Modeling Operating Costs in the Loop Network

Bell System Technical Journal, 1978
A large share of loop network modeling effort is aimed toward characterizing operating costs. These costs arise because of the day-to-day activities associated with providing loop facilities. This paper considers those activities which occur as a result of inward service orders, i.e., requests for a cable pair.
