Toward a Unified Model for Information Quality
نویسندگان
چکیده
We present a model which allows to define in an uniform way information quality dimensions related to heterogeneous types of information, such as structured data managed in data bases, semi-structured and unstructured texts and images. We first define a set of concepts that allow to represent several basic characteristics of such heterogeneous types of information. Then, we introduce a general categorization of quality dimensions and sub-dimensions, which are then specialized to structured data, semiand unstructured texts and images. In so doing, we provide, to our knowledge, a first attempt to unify the information quality issue for heterogeneous information types.

Optimal Locating and Sizing of Unified Power Quality Conditioner- phase Angle Control for Reactive Power Compensation in Radial Distribution Network with Wind Generation
In this article, a multi-objective planning is demonstrated for reactive power compensation in radial distribution networks with wind generation via unified power quality conditioner (UPQC). UPQC model, based on phase angle control (PAC), is used. In presented method, optimal locating of UPQC-PAC is done by simultaneous minimizing of objective functions such as: grid power loss, percentage of n...
متن کاملModel Selection Based on Tracking Interval Under Unified Hybrid Censored Samples
The aim of statistical modeling is to identify the model that most closely approximates the underlying process. Akaike information criterion (AIC) is commonly used for model selection but the precise value of AIC has no direct interpretation. In this paper we use a normalization of a difference of Akaike criteria in comparing between the two rival models under unified hybrid cens...

This paper proposes a novel robust control scheme based on delay-dependent H∞for unified power quality conditioner (UPQC) in a microgrid under the influence of the delay and parameter uncertainties. A new UPQC model considering the effects of the delay and parameter uncertainties is established. Then, the H∞ controller is designed based on the cone complementarity linearization (CCL) algorithm....

متن کاملA UNIFIED MODEL FOR RESOURCE-CONSTRAINED PROJECT SCHEDULING PROBLEM WITH UNCERTAIN ACTIVITY DURATIONS
In this paper we present a unified (probabilistic/possibilistic) model for resource-constrained project scheduling problem (RCPSP) with uncertain activity durations and a concept of a heuristic approach connected to the theoretical model. It is shown that the uncertainty management can be built into any heuristic algorithm developed to solve RCPSP with deterministic activity durations. The esse...
