The aircraft landing gear system retractio...

Accuracy of process data is defined as the sum of the bias of the measurement plus its precision. In this paper, we overview the effect of using data reconciliation in the accuracy of data and we show the benefits of installing data reconciliation thus providing a tool to determine if a data reconciliation package is financially justified. Because new sensors improve the power of data reconcili...

Credit scoring model development became a very important issue as the credit industry has many competitions and bad debt problems.

In order to solve the classification and decrease the Type I error of credit scoring model, this pap...

Relative navigation of an aircraft (fixed wing or helicopter) close to ships at sea is a unique navigation problem. Shipboard helicopter operations provide a difficult operational environment. Wind over deck and wake turbulence shed by ship super structure offer challenging and unpredictable conditions during takeoff and landing. This is especially true in the operational environment that inclu...
