As a result of the use of OLAP technology in new fields of knowledge and the merge of data from different sources, it has become necessary for models to support this technology. In this paper, we propose a new multidimensional model that can manage imprecision both in dimensions and facts. Consequently, the multidimensional structure is able to model data imprecision resulting from the integrat...

Abstract The change of a quantum state can generally only be fully monitored through simultaneous measurements two non-commuting observables $$\hat{X}$$ X ̂ and $$\hat{Y}$$ Y spanning phase space. A measurement device that is cou...

A method for calculating, by selective inhibition, the activities in serum of isoenzymes of alkaline phosphatase (EC 3.1.3.1) originating from bone, liver, intestine, and placenta produced resuIts for a sample of patients for which the imprecision was fiveto 25-fold higher than that of the alkaline phosphatase method used-too imprecise for routine clinical use. Error analysis by direct calculat...

We developed a computer model to study the use of patients' specimens to assess compliance of cholesterol measurement performance with the 1992 goals of the Laboratory Standardization Panel of the National Cholesterol Education Program. The model uses Monte Carlo techniques to simulate cholesterol measurements that are subject to both systematic and random error. Split-sample measurements by a ...

This paper describes a concurrency control technique for real-time object-oriented databases that supports logical consistency and temporal consistency, as well as bounded imprecision that results from their trade-o s. The concurrency control technique uses a semantic locking mechanismwithin each object and user-de ned conditional compatibility over the methods of the object. The semantics can ...

Faulty requirements specifications lead to developing a faulty software system. This may require repeating the whole software engineering cycle wasting time and money. This paper presents an interactive semi-automated system that is a compromise between two approaches. The first tries to avoid the introduction of imprecision while the software requirements are being written. The other attempts ...
