Engine Tests and Boiler Efficiencies

Assessment Delivery Engine for QTIv2 Tests

The IMS Question and Test Interoperability (QTI) standard has not had a great takeup in part due to the lack of tools. In the 2006 JISC Capital, three Assessment projects were commissioned: item authoring, item banking, and QTI-compliant test delivery. This paper describes the ̳ASDEL‘ test delivery engine, focusing upon its architecture, its relation to the item authoring and item banking servi...

Fuzzy-Neural Cost Estimation for Engine Tests

This chapter discusses artificial computational intelligence methods as applied to cost prediction. We present the development of a suite of hybrid fuzzy-neural systems for predicting the cost of performing engine tests at NASA’s Stennis Space Center testing facilities. The system is composed of several adaptive network-based fuzzy inference systems (ANFIS), with or without neural subsystems. T...

Boiler Design Procedure Geothermal Boiler Design Procedure

A concept of "Fractal Fracture Mechanics" for HDR .(Hot Dry Rock) geothermal reservoir design has been developed as an extension of conventional rock fracture mechanics. It is suggested that this concept is successfully applicable to characterize and model subsurface fracture network in HDR geothermal reservoir. Furthermore, this modeling procedure makes it possible to evaluate the thermal ener...
