As the requirements of the systems change, it is desirable to take these changes into account. To do so, the software must be extended to consider the changes. But the problem is that the modifications on software artifacts may cause conflicts and inconsistencies in the structure of the software, which are difficult to find and time-consuming to correct.(More)
The most common way of multi-objective optimizations is assigning a weight to each objective and construct a single fitness function. In this method finding of the appropriate weights is the most important problem. The second method, which is not very well-known for power system researchers, is to optimize the objectives independently. Many optimum answers(More)
Nowadays, DGs are widely used in the power systems to improve the overall conditions of the network. Less environmental impact, high electric efficiency, low variable maintenance cost, quick start up, low installation cost and many other benefits, encourage the system manager to utilize this type of generation in the network. One of the most important(More)
In this paper we propose an observer for attitude and position estimation of a rigid body using data provided by rate gyros, Doppler sensors and a single landmark measurement. Under an observability condition which depends on landmark position, asymptotic convergence of the observer is proved. The initial attitude and position estimates can assume any(More)
We propose an observer for attitude and position estimation of a rigid body using translational and angular velocity measurements together with a single landmark. Under an observability condition depending on landmark position, global and asymptotic convergence of attitude and position estimation errors to zero is achieved. We extend the observer for the(More)
