Operation Earning Power Modelling of the Manufacturing Process
(Universitatea "Dunărea de Jos" din Galați, 2012)In order to better represent the specified goal of the manufacturing process we propose (as a novelty) as a criterion the Earning Power (EP). It is both synthetic (because it reflects the essential motivation of the ... -
Opportunities to Improve the Competitiveness of Romanian Organizations
(“Dunarea de Jos” University of Galati, 2013)Competitive organizations are permanently prepared to identify the cutting-edge technologies which will change the future in business by using the concept of Business Intelligence. Moore's paradigm was a visionary model ... -
Opportunity Analysis for Developing a Micropayment System in Local Area Networks
(Europlus Galati, 2012-03)Although transactions with small amounts of cash are simple and quick, they still present drawbacks. The main issue is to drastically reduce costs for very small electronic payments and solutions have already started to ... -
Optimal Coding for Qualitative Sources on Noiseless Channels
("Dunarea de Jos" University of Galati, 2006)In this paper we perform the encoding for sources which are only qualitatively characterized, that is, each message the source delivers possesses a certain quality, expressed as cost, importance or utility. The proposed ... -
Optimal Control Development System for Electrical Drives
("Dunarea de Jos" University of Galati, 2008)In this paper the optimal electrical drive development system is presented. It consists of both electrical drive types: DC and AC. In order to implement the optimal control for AC drive system an Altivar 71 inverter, a ... -
The Optimal Control for D.C. Position Drive System
("Dunarea de Jos" University of Galati, 2007)A position drive system with D.C. motor is operated using conventional position, speed and current controls. These controls provide a good dynamic and steady-state behaviour, but they do not take in consideration the ... -
Optimal Control for Electric Vehicle Stabilization
("Dunarea de Jos" University of Galati, 2010)This main objective of the paper is to stabilize an electric vehicle in optimal manner to a step lane change maneuver. To define the mathematical model of the vehicle, the rigid body moving on a plane is taken into ... -
Optimal Control Structure for Variable Speed wind Power System
("Dunarea de Jos" University of Galati, 2002)This paper presents an optimal control structure for variable speed, fixed pitch wind turbine. The control objective results from the optimization criterion that includes two contradictory demands: maximization of the ... -
Optimal Control Using Evolutionary Algorithms
(2017)Optimal Control Problems involve dynamic systems that are subject to algebraic or differential constraints and whose evolution may be characterized by a performance index. Such a problem can be solved by the well known ... -
Optimal Convex Controller and Model Reduction for a Dynamic System
("Dunarea de Jos" University of Galati, 2008)This paper presents analysis and design of a family of controllers based on numerical convex optimization for an aircraft pitch control system. A design method is proposed here to solve control system design problems in ... -
Optimazation of Ultrasonic Flow Meters for Crude Oil Metering and Export
(Univeritatea "Dunărea de jos" din Galați, 2012)Ultrasonic flow meters, as all velocity or inference type devices, require an adequate flow stream conditioning in order to assure an accurate performance. Typical flow conditioning consists of straightening the upstream ... -
Optimisation of Refractory Components of Sliding Gate Mechanism for Continuous Casting
