Trace Scheduling A Technique for Global Microcode Compaction. 

Different solutions to this problem have been proposed. In [7], Fisher described a series of transformations used in trace scheduling for microcode compaction. This method compacts the critical path independently of the control block boundaries. A refinement of this tqjproach was proposed recently by Potasman et al and is called percolation scheduling [8]. Camposano and Ber unaschi use an alternative approach called path-based scheduling [9], wh e all possible paths are compacted independently. A post-processing step merges separate paths to Iowa the controller costs. 

Figure 8 shows the trace of the application of Axiom- , Axiom-2, Rule-l, Rule-2, Rule-3, and Rule-4 in our specific scheduling problem. The trace consists of a repeated pattern of rule applications Rule-4 followed by either Rule-2 or Rule-3. At each step the intrasituational rule converts an end-time to a start-time, and then the start-time is matched to the... 

The sulfides of trace elements in soils and sediments are also of importance in controlling the availability and mobility of trace elements, especially for land disposal of sulfide-rich sediments or anaerobic digested sludge. Due to the oxic nature in arid soils, most of the sulfur is present as sulfate thus, this problem may not be pressing. In most current SSD schedules, the majority of the sulfide forms are included in the organic bound or residual fractions.

To achieve adequate binder burn-out is a matter of experience, and size of component, green particle packing, manner of oven loading, temperature/time schedule and atmosphere are all determining parameters. Removal of the final traces of binder residues may be essential especially in the case of some electroceramics, for example superconductors (see Section 4.7.4) where residual carbon could be detrimental to properties. 

The hydrolysis products (23-25) of the three nitrogen mustards listed in Schedule 1 of the CWC were included in the general LC/APCI/MS screening procedures of Black and Read, 14 26 . These procedures, and those of other laboratories, have successfully identified Af-methyldiethanolamine (23) and N-clhyldiclhanolaminc (24) in OPCW proficiency tests. More specific methods based on LC/ESI/MS have been reported for the trace analysis of ethanolamines in environmental residues (66) and biomedical samples (67). 

The determination of chemical elements falls within the scope of the CRL for residues at the Istituto Superiore di Sanita (ISS), Rome [29]. By means of prob-ciency testing, the ISS-CRL constantly monitors the performance of the NRLs as regards the determination of trace elements. Recently, a cooperation was established with the IRMM to organize an IMEP ILC for NRLs on trace elements analysis in tuna bsh. As a follow-up of this cooperation specibc training activities for NRLs are scheduled to be jointly organized by the IRMM and the ISS-CRL. 

Figure 4.4 The HPLC analysis of a reaction mixture containing AMP and alkaline phosphatase. Separations were carried out on a reversed-phase column with a mobile phase of potassium phosphate (pH 5.5) and 10% methanol. The column was eluted isocratically, and the detection was at 254 nm. Two sets of tracings were obtained, according to the following schedules. For the original reaction mixture (A) immediately after the addition of enzyme, (B) after 10 minutes, and (C) after 15 minutes. For the reaction mixture to which had been added EHNA (5 /xAf), an inhibitor of adenosine deaminase, the suspected contaminant (D ) after 2 minutes, ( ) after 10 minutes, and (F) after 40 minutes. (From Rossomando et al., 1981.)...

As it has been discussed in the literature, we also compare the performance of straight Fourier transformation FFT on the NUS synthetic four-line spectrum in Fig. 3. We used the schedules obtained with the best seed numbers as in Fig. 2a and leave the missing time domain data points at zero value. The traces presented in Fig. 3 show that the artifacts due to the sampling schedules and lack of reconstruction are severe and mask the small peaks. However, the intense line is readily observable. Thus, straight Fourier transformation may be an option if one is only concerned with very intense peaks, such as methyl resonances in a protein, and weak peaks are of little concern. This treatment of NUS data may be useful for a quick inspection of an NUS data set to find out whether an experiment has worked. However, it should be followed by a reconstruction effort to retrieve best the full information content of the NUS data.
