Abstract |
In this paper, a nonlinear adaptive speed controller for a permanent magnet
synchronous motor (PMSM) based on a newly developed adaptive backstepping
approach is presented. The exact, input-output feedback linearization control
law is first introduced without any uncertainties in the system. However, in
real applications, the parameter uncertainties such as the stator resistance and
the rotor flux linquage and load torque disturbance have to be considered. In
this case, the exact input-output feedback linearization approach is not very
effective, because it is based on the exact cancellation of the nonlinearity. To
compensate the uncertainties and the load torque disturbance, the input-output
feedback linearization approach is first used to compensate the nonlinearities
in the nominal system. Then, nonlinear adaptive backstepping control law and
parameter uncertainties, and load torque disturbance adaptation laws, are
derived systematically by using adaptive backstepping technique. The simulation
results clearly show that the proposed adaptive scheme can track the speed
reference s the signal generated by a reference model, successfully, and that
scheme is robust to the parameter uncertainties and load torque disturbance. |

Abstract |
The present project has a social focus, which pretends develop a system
(hardware and software) capable to achieve a valuation of the
neuromusclescheletic children’s march, which is cerebral paralysis. This
valuation will be done by several images, representing the march of the studied
subject in a graphic way, to be compared with a normal march patron that will be
evaluated by an expert who will determinate a proper treatment, witch will
inhibit the low extremities’ dominating muscles to improve the subject march. |

Abstract |
Executives are subjected to relentless onslaught of information. Many strategies
have been suggested in the past to negotiate the torrents of information flows
confronting executives. This paper recommends modifying the structure of
information flows reaching the executives as an effective strategy to manage
information overload. Such a strategy will enhance the actionability of the
decisions taken by the executives who use information inflows as inputs to such
decision making. Autonomous software agents can be used for the purpose of
building more effective information inflow structures. |

Abstract |
Cluster analysis is one of the attractive data mining techniques that have been
used in many fields. One of the popular types of clustering algorithms is the
center based clustering algorithm. K-means used as a popular clustering method
due to its simplicity and high speed in clustering large datasets. However,
K-means has two shortcomings. K-means is dependent on the initial state and
convergence to local optima in some of the large problems. In order to these
shortcomings, in an unsupervised clustering the number of clusters needs to be
fixed by a human analyst too. In order to overcome local optima problem and for
determining the number of clusters, lots of studies done in clustering. In this
paper we use a new search heuristic called “Imperialist Competitive Algorithm ”
to find the best clusters with best numbers of clustering. In this algorithm we
assume each clustering solution with special clusters number as a country and
use a new cost function to calculate the clustering cost in each step. We
compared proposed algorithm with other heuristics algorithm in clustering, such
as traditional K-means, IGKA, CSO and GA-PSO by implementing them on several
well-known datasets. Our findings show that the proposed algorithm works better
than the others according to cost function and standard deviation. |

Abstract |
These last thirty years were outstanding by the revolution of technology
possibilities in the field of digital electronics and this, as much as within
context of programmable solutions like (Microcontroller, DSP,…etc), than of
reconfigurable solutions (CPLD, FPGA). Among all these possibilities, Field
Programmable Gate Array (FPGA devises) is a good compromise between the
advantage of the flexibility of a configurability solution, high frequency and
the efficiency of a particular architecture with a high integration density.
In this paper is presents a detailed description of the structure by Indirect
Sliding Mode of Permanent Magnet Synchronous Machine PMSM. Experimental results
carried from a prototyping platform are given to illustrate the efficiency and
the benefits of the proposed approach and the various stages of implementation
of this structure in FPGA. |

Abstract |
Graph theory is used to represent a communication network by expressing its
linkage structure, the vertices represent objects and the pairs called edges or
represent the interconnections between objects. The exact geometric positions of
vertices or the lengths of the edges are not important. The purpose of this
paper is to find a recursive relation counting the number of spanning tree in
Butterfly map that illustrate a connection problem suggested by Erdös and Rényi
in 1962: Let there be given a country with n cities, n large, so that a direct
air connection between two cities would require two busy airports. Considering
the capacity limits of the airport, what is the number of flights that would get
a passenger from any one city to another so that he needs change planes not more
than once? Many results of this problem were given in the past [1], [4] |

Abstract |
The major process in the education methodology is organizing and conducting the
examination. Administration of the question paper setting is an important task
in the objective-type examination system. While setting the objective type
question paper, the highlighted problems are the lack of expertise, the time,
and the questions redundancy. Generally, during the retrieval of records from an
objective type question bank redundancy may occur even for the large size
databank as well as smaller size databank. To solve this problem, a methodology
is required to retrieve records from a database without redundancy. This paper
discusses the impact of mid-square, mid-product and constant multiplier
techniques for random number generation, to retrieve records from the question
bank with minimal redundancy as far as possible. To retrieve records from a
database, a modified approach is identified and applied to generate random
numbers. Also, this paper justifies the role of suggested approach, which
performs reasonably better than the actual techniques reported in the literature
for records retrieval process even for a smaller size database. |
