A knowledge-based interactive system for choosing abstract data structures and concrete represent.* tions for them is described. The system acts as an "expert" on data structures and is to be consulted by programmers during the design stage of their work A specification method is described which assumes a restricted vocabulary of data structure terminology common to the user and the system. The...

nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study  cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

This paper has two main objectives. The first objective is to give a characterization of a qualitative description of a possibility function. A qualitative description of a possibility function is called a consistent possibilistic state. The qualitative description and its characterization serve as qualitative semantics for possibility functions. These semantics are useful in representing knowl...

UNLABELLED The purpose of this study was to explore and describe the opinions of nurses working with tuberculosis (TB) patients regarding hospital discharge plans at Moses Kotane in North-West, South Africa. METHOD A qualitative, exploratory and descriptive study was conducted with these nurses. The population involved registered nurses working with TB patients for more than two years. The po...

A phenomenon as complex as protein folding requires a complex model to approximate it. This thesis presents a bottom-up approach for building complex probabilistic models of protein secondary structure by incorporating the multiple information sources which we call experts. Expert opinions are represented by probability distributions over the set of possible structures. Bayesian treatment of a ...

Central MessageIn upcoming issues of the Journal, readers will have access to a number high-impact Invited Expert Opinion articles on important topics in coronary surgery. In This year, surgery ranging from continued debate surrounding multiple arterial grating (MAG) optimal use graft flow measurement. this era rapidly evolving evidence across field artery bypass grafting (CABG), experts guide ...

In this paper, we proposed a methodology based on group decision making for aggregating and weighting expert knowledge or opinions and identifying the final agreement for a group of experts. We use a case study on causes of Alzheimer’s Disease (AD) for an illustration of the procedural steps in the proposed methodology. We begin by mapping nine most commonly discussed possible causes or risk fa...

Digital preservation workflows for automatic acquisition of image collections are susceptible to errors and require quality assurance. This paper presents an expert system that supports decision making for page duplicate detection in document image collections. Our goal is to create a reliable inference engine and a solid knowledge base from the output of an image processing tool that detects d...
