Speed estimation is the most important issue in sensorless drives for induction motors. Estimation generally is based on the currents and voltages measurements; therefore, the correct speed estimation could be wrong due to deficiencies in the voltages and currents acquisition. This paper presents the effects in the speed estimation caused by the erroneous acquisition of signals in two speed observers. Experiments demonstrate that the performance of observers could be decrease with bad currents and voltages acquisition

The voice transmission over the Internet Protocol or commonly named VoIP over a wireless local area network (WLAN) is becoming a necessity; nevertheless there is a very important problem here, it is the fact that the access points disposition is not ideal to establish a well communication at the WLAN design, since they were initially designed for data transport. This paper presents a procedure for designing WLAN's with VoIP support, using two of the most important current standards for WLAN's, 802.11b and 802.11g

The acquisition of assembly skills by robots is greatly supported by the efective use of contact force sensing and object recognition vision systems. In this paper, we describe the ability to invariantly recognize assembly parts at different scale, rotation and orientation within the work space. The paper shows a methodology for online recognition and classification of pieces in robotic assembly tasks and its application into an intelligent manufacturing cell. The performance of industrial robots working in unstructured environments can be improved using visual perception and learning techniques. In this sense, the described technique for object recognition is accomplished using an artificial neural network (ANN) architecture which receives a descriptive vector called CFD&POSE as the input. This vector represents an innovative methodology for classification and identification of pieces in robotic tasks. The vector compresses 3D object data from assembly parts and it is invariant to scale, rotation and orientation, and it also supports a wide range of illumination levels. The approach in combination with the fast learning capability of ART networks indicates the suitability for industrial robot applications as it is demonstrated through experimental results

When the documentation about the sequence of interactions among the objects in a program is not available but it is required, some work has to be done to document and to obtain the sequence diagrams either by making it in a manual way, or to apply a reverse engineering process that helps to recover the individual diagrams. The present work proposes a computerized method that interprets the characteristics of programs written in C++ code and applies a conversion algorithm that obtains the UML sequence diagrams. To test the method and their conversion algorithm a study case using the work carried out at Gordon College has been taken, which is an automatic teller machine simulator system written in C++

The Hopfield model has problems in the recall phase, one of them it's the time convergence or non convergence in certain cases. We propose a model that eliminates iteration in Hopfield model. This modification in the recall phase, eliminates the iterations and for consequence takes fewer steps, after them, the recuperation of N patterns learned it's the same or little better than Hopfield model. Finally because iteration is eliminated the recuperation time is reduced too

Issues of principle design, functioning and interaction of units and elements of the system are described. The mathematical tools for processing the signal detection, and also for determination of distances and angular measures are examined. The important parameters are analytically determined: expected accuracy, functioning speed, range of action, and power requirements; concluding with the exploration of possible areas of practical use for this automatic navigation system
