Describes i) necessity of fuzzy DataBase ii) techniques used in the storage and retrieval of fuzzy data in a DataBase or information retrieval system iii) DataBase framework for fuzzy DataBase and iv) the advantages of using object-oriented DataBase framework in fuzzy DataBase. A prototype of fuzzy object-oriented DataBase system, (FOODS), has been developed to demonstrate the feasibility of fu...

Continued global economic instability and uncer-tainty is causing difficulties in predicting sales. As a result, many sectors decision-makers are facing new, pressing challenges. In supply chain management, the food industry key sector which sales movement demand forecasting for products more difficult to predict. Accurate helps minimize stored expired items across individual stores and, thus, ...

We consider systems satisfying a matching condition which are functionally known up to a L2 measure of uncertainty. A modified L2 performance measure is given, and the performance of a class of model based adaptive controllers is studied. An upper perfor­ mance bound is derived in terms of the uncertainty measure and measures of the approximation error of the model. Asymptotic analyses of the b...

Throughout the performance of a RF immunity test according IEC 61000-4-3 there are several factors that should be taken into account to ensure the quality and to estimate the uncertainty associated to the results. One phenomenon that should be considered to calculate uncertainty is the disturbing effect produced by the EUT over the electric field generated within the calibrated uniform field ar...

When massaging differential-algebraic equations during an index reduction process, one usually keeps track of structural zeros in order to be able to detect when non-differential equations appear. However, in a numerical setting structural zeros may turn out as small numbers, impossible to distinguish from zero when numerical precision is taken into account. Such coefficients are referred to as...

The article discusses the calibration results of reference standards-copies according to State Primary Standard Mass Unit using new CCL 1007 vacuum comparator and buoyancy artifacts. authors provided historical data on calibrations copies International Prototype Kilogram (IPK) starting from 1892, including Russian prototype № 12. instability kilogram No. 12 corresponds international values is a...

Design to Criteria scheduling is the process of custom building a schedule to meet dynamic client goal criteria using a task model that describes alternate ways to achieve tasks and sub tasks Formerly Design to Criteria scheduling relied on simple expected value characterizations of method outcomes The recent addition of uncertainty to the task model and its ubiquitous application in Design to ...

Poker is ideal for testing automated reason­ ing under uncertainty. It introduces un­ certainty both by physical randomization and by incomplete information about op­ ponents' hands. Another source of uncer­ tainty is the limited information available to construct psychological models of opponents, their tendencies to bluff, play conservatively, reveal weakness, etc. and the relation be­ tween ...

There are several well-known justifications for conditioning as the appropriate method for updating a single probability measure, given an observation. However, there is a significant body of work arguing for sets of probability measures, rather than single mea­ sures, as a more realistic model of uncer­ tainty. Conditioning still makes sense in this context-we can simply condition each mea­ su...
