In present day extrusions using composites, polymers, and other new alloys, the product geometries are extremely complicated. The flow analysis inside an extrusion die using finite element analysis (FEA) is tedious and time consuming. To optimize the design of a die one needs to perform hundreds of runs, requiring several weeks or months of computer time. In the past researchers have used neural networks (NN) to optimize the design and predict flow patterns for newly designed dies of similar geometries. But, even for NN it has been proven that one needs a few thousand runs to train a network and accurately predict the flow. This paper shows a new methodology of using design of experiments (DOE) as a precursor to identify the importance of some variables and thus reduce the data set needed for training a NN. Based on the DOE results, a neural network training set is generated with more variations for the most significant inputs. A comparison of design using only NN versus using DOE and then NN is shown. The results indicate a significant reduction in the size of the training set, the time required for training and improvement in accuracy of the predicted results. To reduce the analysis time, a newly developed upper bound technique was used for generating the training set. The DOE model is extremely fast and can be used for real time (online) control of the process.","PeriodicalId":194215,"journal":{"name":"Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials.

In order to solve these problems, we have proposed and developed an artificial retina chip (AR chip) which combines video camera function (image sensing) and image processing function, in a similar way to the human eyes. The basic principle of our AR chip is based on a novel type of optoelectronic vector/matrix multiplication. The core of the AR chip consists of a two-dimensional array of variable sensitivity photodetection circuits. The matrix corresponding to the input image can be processed in analogue by applying an appropriate electric vector to the chip. The possible image processing functions include conventional image sensing, edge extraction, variable resolution, 2D to 1D image compression, pattern matching, noise elimination, and random access. Several types of the AR chips with different resolution have been developed by using CMOS technology. Among them, we have succeeded in the mass production of 128_!_(J128 pixels) in February 1998. The features of the AR chips over conventional CCDs are fast image processing (on chip image processing), low power consumption, low cost. With use of these advantages, 500 million chips have been used up to date in several application areas which include games, security systems, communication systems, etc. The concept, structure, operation principle, some applications, and future trends of the AR chips are introduced.","PeriodicalId":194215,"journal":{"name":"Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials.

A hardware design for real-time multiple target tracking 实时多目标跟踪的硬件设计

It is assumed that data is provided in the from of blips, taken off 3 consecutive focal plane arrays, operating at visible or infrared wavelengths. In this paper, the task of multiple target tracking is transformed from one of blip-frame data association to one of target clustering, which in turn is broken down and solved in four stages. Each stage is described and mapped with the use of a feed-forward, a recurrent neural network or a set of fuzzy rules. The first and second stages of the solution procedure involve the use of two feed-forward neural network modules, while the third and forth stages use a recurrent neural network module and a set of expert rules module. The multiple target tracking solution procedure is simulated through use of FORTRAN code. In principle the number of targets that can be tracked with the routine is unlimited. However, in reality, the number of targets is dictated by the number of neurons, which in turn is constrained by hardware requirements. Software simulation results shows that the multiple target tracking code is capable of tracking an arbitrary number of targets very efficiently. The program was tested and debugged for use in the tracking of sets of multiple targets; ranging from 2 to 14. Results indicated that once the average acceleration of the targets is adequately evaluated, track files could be developed with 100% accuracy.","PeriodicalId":194215,"journal":{"name":"Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials.

Future kinetic energy missiles must be small, fast, lethal, and maneuverable, which requires the delivery vehicles to operate in a severe loading environment. Innovative designs and manufacturing techniques have been developed to provide an avenue for enhancing propulsion system performance while significantly reducing the missile size and mass requirements. Propulsion units with high strength-to-density ratio filament wound composite motorcases are stronger, stiffer, and more readily producible than their metallic counterparts; however, these structures are susceptible to manufacturing variability and are more easily damaged during handling and storage. This paper discusses the AMCOM motorcase fabrication approach and its applications as well as development efforts in the area of embedded sensor technology for in-process monitoring, structural characterization, damage detection, and service life monitoring of filament wound composite motorcases. The advanced composite material applications have enabled major improvements in system applications for hypervelocity missile concepts and integration to multiple lightweight launch platforms.","PeriodicalId":194215,"journal":{"name":"Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials.
