Building Similarity Maps of the Environment Using Sonar Information for the Navigation of Mobile Robots
("Dunarea de Jos" University of Galati, 2003)
The objective of the work is to present a representation called similarity map
based on some results in the evaluation of the SONAR system of a mobile robot. As
environment a corner of our lab it is considered. Based on ...
On Estimation of the Orientation of Mobele Robots Ising Turning Fuctions and Sonar Information
("Dunarea de Jos" University of Galati, 2003)
SONAR systems are widely used by some artificial objects, e.g. robots, and
by animals, e.g. bats, for navigation and pattern recognition. The objective of this paper
is to present a solution on the estimation of the ...
Artifacts Removing in Ultrasonic Images by Fusion Processes
("Dunarea de Jos" University of Galati, 2013)
Allmost airborne ultrasonic images used in robotics have artefacts and distorstions, when comparing real objects with those presented in ultrasonic images. The differences between reral and reference images have various ...
On Phenomena Based Metamodelling - A Process System Engineering Point Of View
("Dunarea de Jos" University of Galati, 2000)
This work is looking to methodological aspects of process modelling. The
point of view is more from Process System Engineering (PSE) in order to develop
formal and generic techniques for process modelling, and to use ...
On Process Modelling Using Physical Oriented and Phenomena Based Principles
("Dunarea de Jos" University of Galati, 2000)
This work presents a modelling framework based on phenomena description
of the process. The approach is taken to easy understand and construct process model in
heterogeneous possible distributed modelling and simulation ...
On the harmonics reduction using wavelet based signal processing
("Dunarea de Jos" University of Galati, 2000)
This paper presents a method for calculating the reference currents needed for
the command of an active filter. By using the Discrete Wavelet Transform (DWT) the
high-frequency components of the currents are eliminated. ...
An Algorithm for Thresholding in the Context of Signal Denoising with Wavelets
("Dunarea de Jos" University of Galati, 2008)
The problem of estimating a signal corrupted by additive noise has been of
interest to many researchers for practical as well as theoretical reasons. Wavelet based
methods have become increasingly popular, due to a number ...
Force Prediction in Cold Rolling Mills by Polynomial Methods
("Dunarea de Jos" University of Galati, 2007)
A method for steel and aluminium strip thickness control is provided including a new technique for predictive rolling force estimation method by statistic model based on polynomial methods.
On Activity Modelling in Process Modelling
("Dunarea de Jos" University of Galati, 2001)
The paper is looking to the dynamic feature of the meta-models of the
process modelling process, the time. Some principles are considered and discussed as
main dimensions of any modelling activity: the compatibility of ...
Evaluation of two Algorithms for Change Detection Based on Vibration Signals Processing
(Universitatea "Dunărea de Jos" din Galați, 2017)
Change detection and diagnosis are important activities and research
directions, in the field of system engineering and conditional maintenance of the
equipment and industrial processes. The processed signals are coming ...
