The decay of ~(99m)Tc source was used to verify experimentally that in the measurement of the number of atoms of a radioactive isotope in a sample at time t_0, the error introduced through the inaccuracy of its decay constant can be reduced to a much smaller value by the careful selection of the time of measurement or measurements of its radioactivity at around one life time (1/λ) after t_0 and doing the calculation.

Furthermore, a content adaptive IMC algorithm in MCTF, composed of two estimation models, is put forth to reduce the ghosting artifacts. One model is based on characteristic of subbands coefficients for low activity region estimation, and the other is to estimate the MV accuracy in high subbands from the energy after ME. Artifacts, caused by inaccuracy ME or update step, can be reduced effectively by the estimation models.

Analysis for testability is widely used in DFT and test pattern generation, but most testability analysis algorithms have the shortcoming of either inaccuracy or being too complicated. A new method to calculate the signal probabilities of the nodes in IC is pre-sented in Chapter 7 of this dissertation. The signal probabilities by our method is more exact than by the previous ones. A symbol of the signal probability at the fan-out node is created and is propagated to the RFON (Reconvergent Fan-out Nodes). At the RFON, the expression containing the symbol is simplified using the rule which corresponds to the law of identity in Boolean algebra. After the expression is simplified, the symbol is substituted with its numeric value. Theoretical analysis shows that this method is concise and has a low computing complexity.

Meanwhile, it makes it difficult to apply angle conversion system to practical goniometry curcuit. The paper makes improvement on the fast following-up conversion and proposes a high-precision dynamic goniometer system and a nonlinear high-speed following-up conversion mode based on inductosyn. It analyses the causes contributing to the error and deduces the expression bf the basic goniometry errors caused by output signal inaccuracy, and also puts forward the bounds on error of axis-to-angle converting.
