RBF neural network for thrust and torque predictions in drilling operations RBF神经网络在钻井作业中的推力和扭矩预测

{"title":"RBF neural network for thrust and torque predictions in drilling operations","authors":"V. Karri","doi":"10.1109/ICCIMA.1999.798501","DOIUrl":"https://doi.org/10.1109/ICCIMA.1999.798501","url":null,"abstract":"In recent years, radial basis function (RBF) neural networks have been shown to be versatile for performance prediction involving nonlinear processes. Machining performance prediction involving various process variables is a nonlinear problem. The conventional mechanics of the cutting approach for predicting thrust and torque in drilling makes use of the oblique cutting theory and an orthogonal cutting databank. The quantitative reliability, in these models, depends on the 'input parameters' along with the 'edge force' components from the orthogonal cutting databank for that given work material. By contrast, neural networks for drilling performance prediction have been shown to be successful for quantitative predictions with minimum number of inputs. In this paper, an RBF neural network architecture is proposed which uses process variables such as tool geometry and operating conditions to estimate thrust and torque in drilling. Extensive drilling tests are carried out to train the RBF network. The developed network is tested over a range of process variables to estimate thrust and torque. It is shown that, using the neural network architecture, the drilling forces are 'simultaneously' predicted to within 5% of the experimental values.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

An SNBN provides a natural mechanism for incremental network growth, and we develop a constructive algorithm based on the inductive learning method for the network. Simulation results of forecasting, approximations of nonlinear functions and approximations of multivariate polynomials are given in order to highlight the capability of the network.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

As there is no complete set of techniques for designing any FPGA program, researchers have been successful in evolving program designs using genetic algorithms (GAs). However, using GAs to generate software programs for FPGAs faces two main problems, namely scaling and errors. In this paper, we present our on-going research towards overcoming these problems by the integration of GAs with case-based reasoning (CBR). CBR is a problem-solving method that reuses old solutions to solve new problems. Our research work aims to apply CBR to reuse genetically evolved FPGA programs in order to develop larger programs at a reasonable computational expense. This paper describes our preliminary experiments and their results, which are encouraging.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

This formalization of software evolution is based on a hypergraph and extended to an evolutionary hypergraph with different software evolution objects. In an evolutionary hypergraph, a top-level software evolution step can be refined into several finer software evolution steps and related top-level software evolution components can be decomposed into finer software evolution components. The hypergraph model, in conjunction with prototyping, can help developers describe and understand software evolution processes. We provide an example of multimedia system evolution to illustrate this formalization.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

The main difficulties lie in the matching of different elements of every image, the so-called correspondence problem. According to the trend of analysing singular points of the scene, we opt for a system based on the labelling and matching of contours and corners of the scene. Those points have some properties that make the method usable for most kinds of images. In order to obtain the contour information, a new algorithm is developed which is hardware implementable, able to autoadapt its parameters to external characteristics (such as as focus, illumination, contrast, etc.), and provides high reliability to the depth obtaining system. A specialised hardware is designed for contour obtaining and labelling with a fast and highly efficient pipeline architecture that gives the system a fast response time.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

Visual image retrieval on compressed domain with Q-distance 基于q距离的压缩域视觉图像检索

{"title":"Visual image retrieval on compressed domain with Q-distance","authors":"Hong Yu","doi":"10.1109/ICCIMA.1999.798544","DOIUrl":"https://doi.org/10.1109/ICCIMA.1999.798544","url":null,"abstract":"This paper proposes a new image retrieval scheme that works directly on compressed image (JPEG) databases. As we know, a large percentage of the image databases are stored in compressed image format, such as JPEG format. In addition, about half of the images on the Internet are also in JPEG format. Thus, image retrieval systems that require JPEG decompression greatly limit the speed of image searching. Subsequently, new methodologies for retrieving of images without JPEG decoding is needed for Web image search and compressed image database retrieval. We propose a new metric, Q-distance, that can be utilized to measure the distance between two compressed images. A system that uses Q-distance for fast image retrieval is also presented. Experiment results show that Q-distance is robust against variation and this new retrieval scheme, which directly works in the compressed image domain, is fast to execute and suitable for Web image searching and retrieval.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.
