RAC publications include data summaries for specific component types, such as hybrid microcircuits, small, medium and large-scale integration digital devices, linear and interface devices, digital monolithic devices, and discrete semiconductors. In addition, there are reliability and equipment maintenance data books that provide the failure and repair time data on military electronic equipment by application such as subsystem. 

The kinetics of alkaline hydrolysis of an ester can be followed by the pH-stat method, in which the pH is held constant by adding a solution of strong alkali to the reacting ester solution. The volume of alkali added in order to keep the pH constant is recorded as a function-time. Find the volume function needed to determine the rate constant that is, given the volume-time data for this type of experiment, what plot or calculation will yield the rate constant ...

There are two major data-type classifications time-domain and frequency-domain. Each of these can be further divided into steady state and dynamic data formats. In turn, each of these two formats can be further divided into single-channel and multi-channel. 

Vibration profiles can be acquired and displayed in one of two data types (1) time-domain or (2) frequency-domain.

In electronic data packages used in held studies, there are some electronic data that are directly entered by the held investigator (FI) and some that are generated by the program (e.g., dates and times). Both types of raw data need to be verified by QA personnel, who should check not only directly entered data, but also computer-entered data. In order to conduct a thorough data audit, QA should determine which data are direct entry and which are automatic. 

The RPL language is designed for easy-to-write, compact programs. Like APL, it supports a run-time environment in which variables can represent different data types at different times. There is no need for the kind of data declarations which make programming awkward in traditional languages. 

Normally, time-resolved FT-IR spectroscopy (TRS FT-IR) possesses the same data characteristics. In a typical TRS FT-IR experiment, interferograms are assembled for a specific delay time after the photolysis pulse, and the data produced are normally finer-grained in frequency than in time. This type of experiment is complementary to experiments with fine-grained time information. It is particularly useful where a wide spectral range is necessary and works reasonably well for highly reproducible events which occur on relatively long timescales (fractions of seconds) (83). It is also an appealing system for use on shorter timescales, and it has... 

Material flow and resource allocation can be defined by time, duration, type and quantity in the planning model. They describe a definite (by best current knowledge) change of the planning model in the future. In addition to this there are a number of fuzzy information data that have to be included in the planning model but are only weak assumptions about the future planning situation. These include, e.g., planned orders and planned independent requirements. 

We also came up with another interesting statistic in our analysis of these data. On this table (Table III) I have summarized the frequency of commercialization within certain time frames after the expiration of the mandatory 90 days from receipt of the PMN by EPA. As you can see, most companies want to produce and sell their new chemical as soon as possible. We have not had time to analyze these data further but it would be interesting to see if there is any relationship between commercialization time and type of chemical, end use or market, size of company, volume of production, etc. 

At the same time, several types of data necessary to ensure proper management of occupational risks associated with a drug substance are not generally useful in evaluating potential patient risks. So the necessary tests—eye and skin irritation, sensitization and inhalation toxicity, as well as assessment of the hazards of byproducts and impurities that do not get incorporated into the final therapeutic product—are not performed in the normal course of development. 

In the following discussion, we shall again separate the terms of a hyperbolic model and identify two parameters Cl and C2. As before, each of these two parameters will be a collection of terms, one of which is multiplied by conversion and one not multiplied by conversion. In previous formulations, however, we have oriented the discussion toward a familiar type of experimental design in kinetics conversion versus space-time data at several pressure levels. Consequently, the parameters Cx and C2 were defined to exploit this data feature. Another type of design that is becoming more common is a factorial design in the feed-component partial pressures. 

The fragility of the five data types will depend on the specific circumstances of the incident. It is not possible to offer a prescribed priority. In general, historical paper data such as procedures, maintenance records, and drawings are less fragile than people and physical data. The team should identify time-sensitive data as one of its first tasks, prioritize the data, and implement measures to collect or preserve the data. 

Most NMR spectra consist of a number of signals and their time-domain spectra appear as a superposition of a number of traces of the type shown in Figure 5.3. Such spectra are quite uninterpretable by inspection, but Fourier transformation converts them into ordinary frequency-domain spectra. The time-scale of the FID experiment is of the order of seconds during which the magnetisation may be sampled many thousands of time. Data sampling is accomplished by a dedicated computer that is also used to perform the Fourier transformation. 

There are further links across the data types. For example, from time to time we group continuous, score or count data into ordered categories and analyse using techniques for ordinal data. For example, in a smoking cessation study we may reduce the basic data on cigarette consumption to just four groups (Table 1.2). accepting that there is little reliable information beyond that. 

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. 

Voltammetric techniques are quite useful for the direct measurement of the stability of some pharmaceuticals in aqueous solution. Depending on the compounds involved, voltammetry can be used to monitor either the decomposition of a drug or the formation of a decomposition product. This type of study is typically performed by applying a potential to the working electrode that is on the voltammetric plateau for the starting material or end product to be monitored. The resulting current versus time data provide the desired kinetic information. 

Note Whether the member variable compoundList of CompoundLibrary should be declared as an interface—List or a concrete type—ArrayList should be determined on a case-by-case basis. If the concrete class has methods that are not defined in the interface or the abstract class, you are better off defining the variable as the concrete type. Otherwise, you need to explicitly cast the variable to the concrete type every time you use those methods. Either way, the clients of CompoundList are no longer affected by the decision made by the developer of CompoundLibrary with regard to the data type of compoundList variable, which is what abstraction or encapsulation is all about. 

Table 10.5 provides performance data regarding the SCWO process. Typical destruction efficiencies (DEs) for a number of compounds are also summarized in Table 10.5, which indicates that the DE could be affected by various parameters such as temperature, pressure, reaction time, oxidant type, and feed concentration. Feed concentrations can slightly increase the DE in supercritical oxidation processes. For SCWO, the oxidation rates appear to be first order and zero order with respect to the reactant and oxygen concentration, respectively. Depending upon reaction conditions and reactants involved, the rate of oxidation varies considerably. Pressure is another factor that can affect the oxidation rate in supercritical water. At a given temperature, pressure variations directly affect the properties of water, and in turn change the reactant concentrations. Furthermore, the properties of water are strong functions of temperature and pressure near its critical point. 

Another consideration is whether zero-time data for a batch in one container-closure may be used for the same batch in a different container-closure system. This would depend on the amount of time between packaging of the product and zero-time as well as the stability profile of the product. The data generated for zero-time for a batch in one type of container-closure are usually also used to evaluate the same batch in the same container-closure under different storage conditions.
