Inspection of loaded printed circuit boards (PCBs) using 3D laser striping range data is described. The work presented here is intended to assess the feasibility of using 3D depth data for robust identification of PCB defects. A knowledge-based control system interrogates a 2D CAD database for PCB layout information. Test strategies are then implemented with efficient multiresolution data capture. Inspection algorithms use 3D scene models to detect and interpret faults. This paper describes the implementation of the 3D ...

ABSTRACT: In this paper, we briefly discuss the use of alternative urban development proposals (AUDP) as a knowledge resource. The article combines a theoretical reflection with an applied study of urban planning in the Brussels-Capital Region. In the beginning, we present different types of alternative proposals and discuss how they can be evaluated and represented systematically. Afterwards, we test these inferences by applying one specific mapping tool-conceptual graphs- to the context of Brussels-Capital Region and compare the discourses of four urban investigations that were developed for the European Quarter. In conclusion we review the value of alternative development projects as a source of knowledge and make future recommendations for collective analysis, as well as collection and production of different kinds of knowledge in urban policy making.

This paper introduces a novel knowledge based neural network models that incorporate and adapt both existing logistic regression formulas and kernel functions in there structures to improve the learning and adaptation ability of a connectionist model when there is an existing knowledge on the problem in the form of a logistic regression. Different from standard feed-forward neural networks, the proposed

Alzheimer’s disease (AD) is the major cause of dementia in the elderly. The biochemical changes that precede AD may be present up to 20 years before the clinical manifestation of the disease. The translational development of AD biomarkers may be theoretically achieved via two different strategies: the first strategy can be defined as ‘knowledge-based’ (deductive method), while the second one

Phenolic compounds are major constituents of red wines and impact on certain wine-quality parameters. This study has aimed to increase the knowledge base on the phenolic composition of South African red wines by HPLC quan-tification of 39 individual phenols and 2 polymeric, phenolic groups in 260 South African wines of the cultivars Pinotage, Shiraz and Cabernet Sauvignon. Statistical analysis of the collected data revealed significant cultivar dif-ferences in the levels of many of the analysed compounds, as well as in the ratios in which specific anthocyanins are found in the wines. These data may be helpful in the cultivar authentication of wines of these cultivars. Discriminant analysis of the data showed statistically significant separations of cultivars, based on their polyphenol composition, and also how the use of data from a specific wine-producing area or vintage improved the possibilities for success-ful authentication. The data were collected from both pure cultivar wines...

Abstract. This paper describes the design of and experimentation with the Knowledge Query and Manipulation Language (KQML), a new language and protocol for exchanging information and knowledge. This work is part of a larger effort, the ARPA Knowledge Sharing Effort which is aimed at developing techniques and methodology for building large-scale knowledge bases which are sharable and reusable. KQML is both a message format and a message-handling protocol to support run-time knowledge sharing among agents. KQML ...

Agile and flexible manufacturing systems make it mandatory that control programs have features such as agility, flexibility and reusability to meet fast changing, customer demands. To cope with this, a task-oriented model of the control system provides control code, data mapping and generating PLC code according to assembly sequences. The model is defined with the unit functions which can describe
