چکیده
Abstract In the geodetic data processing field, most methods for dealing with inequality constraints model are based on additive random error (ARE) models, and there have been few studies mixed multiplicative (MAAMRE) models constraints. To address this problem, a MAAMRE is first established definition of constraint equations, then, corresponding parameter estimation algorithm proposed idea an exhaustive search method. addition, considering ill-posed iterative regularization solution derived, specific further by applying approach. Finally, feasibility advantages algorithms verified global positioning system (GPS) elevation fitting digital terrain (DTM) examples. Graphical

Additive, multiplicative, and mixed analytical errors.
Depending on the change in magnitude of analytical error occuring with change in concentration of analyte, two limiting types of error properties can be defined: additive and multiplicative. We investigated whether one of these two error types also characterizes the overall error of methods involving multiple procedural steps, or whether mixed error properties result in these cases. Using "open...
متن کاملLinear Mixed Effects Models under Inequality Constraints with Applications
Constraints arise naturally in many scientific experiments/studies such as in, epidemiology, biology, toxicology, etc. and often researchers ignore such information when analyzing their data and use standard methods such as the analysis of variance (ANOVA). Such methods may not only result in a loss of power and efficiency in costs of experimentation but also may result poor interpretation of t...

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Additive and multiplicative piecewise-smooth segmentation models
We propose new models to segment images corrupted by additive or multiplicative noise, in a variational level set approach. In the additive case, we decompose the data into the sum . Here, is a piecewise-constant component, capturing edges and discontinuities, and it is modeled in a level set approach, while is a smooth component, capturing the intensity inhomogeneities. The additive noise is r...
متن کاملOn Additive and Multiplicative Fuzzy Models
Systems which use a fuzzy rule base and an inference mechanisms are quite frequently used in many applications. Fuzzy rules and inference mechanisms can be described by a system of fuzzy relation equations. A solution to a given system of fuzzy relation equations can serve us a proper model of fuzzy rules (fuzzy model for short). But only two particular solutions, let us call them disjunctive a...
