The convergence property for doing logic programming in Hopfield network can be accelerated by using sign constrained method and new modified learning rule. In this paper we compare the performance of doing logic programming task using the both methods. The capacity and attractor performance of these networks is tested by using computer simulations. In this paper, it has been proven by computer simulations...
A few years ago there is revolutionary change in data mining and bioinformatics. Data mining techniques and tools play important role in field of bioinformatics. It is very useful to use data mining techniques to evaluate and analyze bio-medical data. In this paper authors purpose a frame work for intelligent data mining system for bio databases. This system allows scientist to apply bio data analysis...
After events of 9/11 critical infrastructure protection (CIP) gained increased attention. Although at the very beginning the problem seemed overwhelmingly demanding because these infrastructures are indeed very complex, it turned out that, step by step, a systematic approach could be taken, which would make CIP related problems manageable. However, existing reference approaches in this area (like...
Every research field (domain) has a lot of data or information in textual format. The main problem is how to optimally arrange and transform the textual data or information to explore research issues. The authors propose a framework that may help in exploration of research issues from text of specific field (domain). First textual data or information is transformed to semantic network by using some...
Business decision-making is not a simple task. There are many reasons for that but one of the main reason might be that data comes from different operational sources of an organization and it is difficult to organize and maintain especially if a huge volume of data is involved. A Data warehouse is helpful in this regard as it can assist in business decision-making by collecting data from different...
Robotics is evolving at a high speed, and its applications in the industry is also increasing from object pick and place robots, to move and locate robots. The field of robotics is moving so quickly encompassing a wide range of disciplines and applications that robotics education must be adaptive and incorporate a multidisciplinary approach. The actuator designed in this paper is a robotic arm with...
Robotic systems are capable of solving repeated problems more efficiently and effectively than human beings. Today robots are required to have perfect coordination and interaction with the humans, the theme of this paper is to discuss 3 robots which work in coordination with human to perform the tasks once accomplished by the ancients. The implementation of these robots was the theme of RoboCon 2009...
The direction implementation of Lagrange-type variable fractional-delay (VFD) digital filters does not lead to a Farrow structure with linear-phase subfilters. This paper revisits the existing transformation matrix for transforming the odd-order Lagrange-type VFD filter into a Farrow structure and shows the frequency response errors after the transformation. Then, the results using a new transformation...
Recently, great interest has been the reluctance to move to DC motors and its applications in industry Such as robotics, textiles, and household electric vehicle or application or Aviation domains. The first control techniques used classic controllers have been difficult and complicated because of their requirements for a position sensor of the rotor. The position sensor rotor is an important contribution...
This paper presents a proposition of sliding mode position controller of stepper motor - two phase are commonly used in low-cost open-loop positioning control systems. However, acceleration and deceleration are limited and operating open-loop can cause the loss of steps and stalling of the motor. To overcome these inherent problems, a low-cost minor closed-loop position control system (SMC) was developed...
In fractal image compression the encoding step is computationally expensive, because every range block must be compared to all domain blocks in the codebook to find the best-matched one during the coding procedure. In this paper, a fast fractal encoding algorithm using DCT coefficients-based Metric operation is proposed. Simulation results show that the runtime of the proposed algorithm is reduced...
Sliding mode control is a typical nonlinear control strategy which was easy realized and with strong robustness, in this paper, a neuro sliding mode controller was designed with RBF neural networks and the stability of the proposed control scheme is proved by Lyapnouv theorem. For the chattering of sliding mode control are often derive from switching gain, the gain was adjusted with neural networks...
