Electro optical techniques including EOFM (Electro Optical Frequency Mapping) and EOP (Electro Optical Probe) are common dynamic optical probing techniques used during failure analysis. This paper demonstrated two real cases to show the application of these techniques on the fault isolation of high resistive vias.

In this paper, we consider performance assessment method in integrated test. Test and evaluation (T&E) is defined as the demonstration, measurement and analysis of the performance of a system, and the assessment of the results. The importance of system performance assessment model in T&E is illuminated through mathematical description of integrated test. In order to solve the problems that conventional regression analysis can not deal with nonlinear performance output and complex interactions between different factors in T&E of hightech weaponry, a metamodel-based performance assessment method is put forward. Taking Kriging and radial basis function as examples, contrastive analysis for fitting performances of metamodel and conventional polynomial regression is made. Simulation results show the superiority of metamodel in performance assessment for integrated test.

In order to study the breakdown characteristics of oil-paper insulation under compound electric field, the typical oil-pressboard insulation model was adopted according to the insulation structure in converter transformer. The electric field in oil and oil-impregnated pressboard was simulated according to the equivalent circuit for the above model, and the breakdown characteristic test for typical oil-pressboard insulation, oil and oil-impregnated pressboard was carried out separately under compound electric field. To analyze the relationship between the breakdown strength and electric field, the electric field expressions for oil gap and the oil-impregnated pressboard were derived under compound voltage with different AC content. The test result shows that breakdown voltage of oil-pressboard insulation rises first and falls later under compound voltage. According to the characteristics the electric field distribution and breakdown strength of oil gap and oil-impregnated pressboard, it can be found that the breakdown strength of oil-pressboard insulation mainly depends on electric field distribution and breakdown characteristics of oil and oil-impregnated pressboard under compound voltage.

Under the concept of SOA, a new platform structure is present using RIA technology as the presentation layer. Contrast to the traditional E-Government GIS platform, this new mode improves in three fields: the integration of graphics and form, the visualization of structured data and the diversification of thematic map. From the standpoint of technical advantage, platform frame and function realization, this paper prove that the new model can effectively solve the three problems above.

First, an analysis of the status of the military power station (MPS) and its measure-control system (MCS) in the weapon system and modern war were presented. Then presentation of construction and principle of distributed MCS, types of the measured signal, characteristics of simulative load and its switch-control signal were discussed. Finally, a discussion of the main technical issues and solutions in this distributed MCS system were given.

The minimum mean-squared error (MMSE) linear detector has been used for demodulation of the direct-sequence code-division multiple access signals. The blind MMSE linear detector can be implemented by the Griffiths' adaptation algorithm. However, its convergence speed is limited by the wide eigenvalue spread of the correlation matrix associated with the received signal vectors. In this paper, the transform domain Griffiths' adaptation algorithm is proposed to improve the convergence properties. Computer simulations show that, by using orthonormal transforms, the adaptation speed can be improved, especially in the presence of strong interference.
