Real-time data

While steady-state data provide a snapshot of the machine, dynamic or real-time data provide a motion picture. This approach provides a better picture of the dynamics of both the machine-train and its vibration profile. Data acquired using steady-state methods would suggest that vibration profiles and amplitudes are constant. However, this is not tme. All dynamic forces, including mnning speed, vary constantly in all machine-trains. When real-time data acquisition methods are used, these variations are captured and displayed for analysis. 

Data to demonstrate the stability characteristics of both the drug substance and the drug product must be collected. Studies using three different batches of both substance and product in their respective containers/packaging must be conducted. Real-time data should be collected under conditions of temperature and relative humidity in line with the recommended storage. Conditions in different world climatic zones must be taken into consideration for cases where normal environmental... 

Storage conditions will be used. Standard conditions to simulate normal storage are temperatures of 25 or 30 °C and relative humidity of 60 or 65%. A minimum of 12 months real-time data is required for a marketing authorisation application. Real-time data should be supported by accelerated and intermediate stress testing at higher temperature/relative humidity. Photostability should be verified using a single batch. 

Minor changes do not have to be notified to the FDA by a specific supplement, but may be included in the next Armual Report. Minor changes would include editorial corrections to labelling, deletion or reduction in an ingredient intended to affect the colour, replacement of equipment with similar equipment, or the extension of shelf life based on real-time data.

The real time data (the process reaction curve) in most processing unit operations take the form of a sigmoidal curve, which is fitted to a first order with dead time function (Fig. 6.2) 1... 

While the experiment 1s running, informational messages are logged to a printer designated for that purpose. Real-time data (temperatures, pressures, etc.) can be displayed using laboratory or office terminals. The researcher can also view the data analysis results for the latest set. 

Once a test 1s complete, another menu option provides the data analysis results 1n the form of a hard-copy report printed on the local line printer. The report Includes experiment identification Information and the apparent viscosities calculated for each data set. A subset of the data analysis program 1s scheduled automatically by the control programs while the experiment is 1n progress and provides immediate on-line analysis of apparent viscosities for each data set as It 1s collected. The results are viewed using the real-time data display program (Figure 5). 

At any time during the experiment, the researcher can view a real-time display of the instrument s data. These data Include the current sample temperature, the current sample pH and the current delta pressure readings. Also displayed Is the status of all digital Inputs (pumps, valves, etc.), the data analysis results from the latest data set and the experiments In the queue waiting to be run on the Instrument. These real-time data are updated approximately once per second with the entire display being refreshed approximately every 30 seconds. 

The main objective for an intelligent system in electrolyser operations is to gather and process valuable information for a greater control and efficiency. To achieve the aforementioned objective, two key functions have to be performed properly. Firstly, accurate and precise real-time data need to be obtained and secondly, the system should be able to process and interpret these data based on fundamental and acquired industrial electrochemical knowledge. In the case of R2 s EMOS , this second key element refers directly to its capability to use embedded human expertise to find optimal operating solutions and to detect and correctly identify equipment degradation or other anomalies.

Figure 1.2 Comparison of parallel and hierarchical screening strategies.ln the parallel screen the first three assays are run in parallel followed by a manual decision to reduce the candidate compounds down for the subsequent set of three assays. The use of real-time data QC steps and feedback in the hierarchical approach supports the filtering out of failed compounds prior to submission to the next assay. Both strategies...

Ideally the ADME/Tox screening laboratory service vould be set up to fiexibly offer choice in the screening strategy that best fits the current campaign circumstances. It vould also provide real-time data feedback both to enable researchers to use the critical information to make decisions on further testing and to reduce cycle times by eliminating compounds midcampaign [6]. 

The automation of the SEC/Viscometer detector system is achieved by interfacing the DRI and viscosity detectors to a microcomputer for real time data acquisition. The raw data subsequently are transferred to a minicomputer (DEC PDP-11/44) for storage and data reduction. The automated data acquisition and analysis system for the size exclusion chromatograph with multiple detectors used in this study have been described previously.(23)... 

In addition to the high-pressure assembly, the modified system incorporates a new real-time data collection system coupled with a PC based computer. Experimental parameters, such as the valve firing sequence and the reactor temperature-control program, can be set from the computer. Reactants are introduced through two high-spe pulse valves or two continuous feed valves that are fed by mass flow controllers. In high-speed transient response experiments, the QMS is set at a particular mass value and the intensity variation as a function of time is obtained. In steady-flow experiments. 

Thus far there have been two proposed systems for this type of interactive use. The two modes available for this real time data acquisition would be 1) a modified digitizing technique and 2) a direct data entry technique. 

Under the second type of real time data acquisition, we have direct entry methods where essentially you are incorporating an actual terminal into the sensory evaluation booth itself. The electronic terminal would include a data entry keyboard as well as a display screen for receiving results and prompts from the microcomputer (4). This technique has been developed in our laboratories and we feel that it holds tremendous promise in terms of the versatility and the viability for expanding into different areas of sensory evaluation. 

Since in our pharmaceutical network simulation models we deal with packets, let us explain a few aspects of packet formats. Packets carry information and can be sent between transmitters and receivers. In our example, packets can carry robot programs when uploaded from the design/programming office servers to the robot lines and then to the individual CNCs, or robots, or parts of them if there is a need for an update, edit, quality control, production control, maintenance, and other data. (Packets can include mission-critical, panic related real-time data between the robot controller PCs and the line servers.)...
