4. Adaptive Approximate Record Matching

Ramin Rahnamoun

Volume 03, Issue 01 , Winter 2014, Pages 23-27

Abstract
  Typographical data entry errors and incomplete documents, produce imperfect records in real world databases. These errors generate distinct records which belong to the same entity. The aim of Approximate Record Matching is to find multiple records which belong to an entity. In this paper, an algorithm ...  Read More

Shahram Javadi; Mohammad Hossein Hazin

Volume 03, Issue 01 , Winter 2014, Pages 29-35

Abstract
  In this paper presents a Maximum Power Point Tracking (MPPT) technique based on the Hill Climbing Search (HCS) method and fuzzy logic system for Wind Turbines (WTs) including of Permanent Magnet Synchronous Generator (PMSG) as generator. In the conventional HCS method the step size is constant, therefor ...  Read More

6. Artificial Intelligence Based Approach for Identification of Current Transformer Saturation from Faults in Power Transformers

A. R Moradi; Y Alinejad Beromi; K Kiani; Z Moravej

Volume 03, Issue 01 , Winter 2014, Pages 37-46

Abstract
  Protection systems have vital role in network reliability in short circuit mode and proper operating for relays. Current transformer often in transient and saturation under short circuit mode causes mal-operation of relays which will have undesirable effects. Therefore, proper and quick identification ...  Read More
