Selecting Multiple Events

A further extension of the DFG S19 method was achieved when polar analytes and those unsuitable for GC were determined by LC/MS or more preferably by liquid chromatography/tandem mass spectrometry (LC/MS/MS). Triple-quadrupole MS/MS and ion trap MS" have become more affordable and acceptable in the recent past. These techniques provide multiple analyte methods by employing modes such as time segments, scan events or multiple injections. By improving the selectivity and sensitivity of detection after HPLC separation, the DFG S19 extraction and cleanup scheme can be applied to polar or high molecular weight analytes, and cleanup steps such as Si02 fractionation or even GPC become unnecessary. 

Basic course of events 1. User logs in to software, initializes the system, and selects a protocol 2. The system asks for the following information (a) How many samples will be diluted (b) What are the sample dilution factors (c) How many diluents will be used 3. The user enters the relevant information 4. The system displays a deck layout that shows where to place samples, labware, tips, and diluent System allows user to select multiple protocols System will ask user for the following Number of samples Dilution factors Number of diluents The system will prompt the user to place labware in the correct location... 

Figure 7.7 Rank-by-feature framework interface for scatterplots (2D) Scatterplot Ordering. All 2D scatterplots are ordered according to the current ordering criterion (a) in the ordered list (c). Users can select multiple scatterplots at the same time and generate separate scatterplot windows to compare them in a screen. The score overview (f>) shows an overview of scores of all scatterplots. A mouseover event activates a cell in the score overview, highlights the corresponding item in the ordered list (c), and shows the corresponding scatterplot in the scatterplot browser d) simultaneously. A click on a cell at the score overview selects the cell and the selection is fixed until another click event occurs in the score overview or another selection event occurs in other views. A selected scatterplot is shown in the scatterplot browser id), where it is also easy to traverse scatterplot space by changing the x- or y-axis using item sliders on the horizontal or vertical axis. (The dataset shown is demographic- and health-related statistics for 3138 U.S. counties with 17 attributes.) (See color insert.)...

This list could be topped by the standard Windows commands Ctrl +Z and Ctrl+Y (Undo and Redo) as well as Ctrl+C (Copy), Ctrl+X (Cut), and Ctrl + V (Paste). Of course holding the Ctrl key (or Shift key) while selecting events allows you to select multiple events. And don t forget the Windows motto— Save early, save often Ctrl+S. 

The Selection Tool on the toolbar in ACID can also be used to select multiple events. Click the Selection Tool button on the toolbar or press the D key on your keyboard to cycle through the various editing tools. To select multiple events, click and draw a rectangle on the timeline (as shown in Figure 2.24). 

A close relative of the Copy-Paste operation, duplicating events (in combination with selecting multiple events) is one of the most useful ACID skills you can acquire. Not only is it useful for a repetitive copy-and-paste task involving a single event, but you can duplicate entire sections of a project. Repetition in a song is an important structural element that cannot be ignored. 

Some specifications fully determine the outcome of an operation. Our specification of squareRoot allows many implementations and even more than one result 2 2 are 4, but so are -2 -2. If we want to exclude the latter, we would add y>0. Similarly, schedule course constrains the new session to be assigned a qualified, available instructor but does not specify which one be assigned. And takeShortestPath does not say which path should be selected in the event there were multiple paths with the same length it says only that there is no path with a shorter length.

Once the actual incident scenario is understood and its multiple causal factors identified, this information may be used to determine the incident s root causes. One means of performing root cause analysis involves the use of ready-made, predefined trees. A predefined tree provides a systematic approach for analyzing and selecting the relevant elements of the incident scenario. It is a deductive approach, looking backward in time to examine preceding events necessary to produce the specified incident.
