Serial data sets

Data sets are compilations of data, such as spectra or property tables. These data sets are often published serially as loose-leaf services, but the content is not always organized in chapters as in other serial publications. The citation of a serial data set should contain the title of the data set, the publisher, the place of publication, the date of the volume, the data entry number (as opposed to the data value), and the name of the figure or other identifying information. The page number can be included in the citation if page numbers are used in the index of the data set. 

Let us consider again the system defined in Example 5.1. From the application of the global statistical test, gross errors were detected among the data set as indicated in Example 7.1. Now the serial elimination strategy will be applied to isolate the source of gross error, that is to identify which set of measurements contains gross error. 

A data reconciliation procedure was applied to the subset of redundant equations. The results are displayed in Table 4. A global test for gross error detection was also applied and the x2 value was found to be equal to 17.58, indicating the presence of a gross error in the data set. Using the serial elimination procedure described in Chapter 7, a gross error was identified in the measurement of stream 26. The procedure for estimating the amount of bias was then applied and the amount of bias was found... 

A microcontroller board for sensor read-out was developed in collaboration with AppliedSensor (Reutlingen, Germany). This board provides the power supply and the necessary reference voltages and currents to the sensor chip. The sensor chip is mounted on a socket and connected to the microcontroller. The microcontroller provides a set of commands for programming and reading the on-chip registers, controller parameters and sensor values. The microcontroller also manages the data transfer between the f C interface of the microchip and a serial RS-232 interface for external read-out via a PC. The data stream is continuously read out in the measurement mode. Each data set contains the temperature of the microhotplate, the chip... 

The first block DIV is a frequency divider. This block has 2 modes of operation, the normal mode and the test mode. In the test mode, the UART chip runs 16 times faster than in the normal mode. Also, the transmission data rate of the UART chip is 16 times faster than the receiving rate. Each block is initialized by setting the reset line low by applying a 0 to port MR. The TX block accepts 8-bit parallel data from the microprocessor interface (MP) block and transmits it serially to the RS-232 port through port DOUT. Conversely, the RX block receives serial data input, and sends it in 8-bit parallel format to the MP block. Again, the transmitter runs at 16 times the speed of the receiver. The microprocessor interface (MP) block asynchronously controls the parallel data flow between the RX / TX blocks and the microprocessor data bus. 

This introduces a new way in which sequences are used within a database. In previous chapters, the Serial data type was used to create a column of unique integers. When the Serial data type is used, a sequence is automatically created and the default value of the column is set to be the next value in the sequence. In this way, a unique set of integers is ensured. In the above example, more control is needed over the use of sequence values in the sample. id column. This is because this table may contain several rows with the same sample id, each with a different compound id. The sample consists then of all compounds in the sample table having the same sample id. 

A brief comparison of this data set with the results obtained for Illinois No. 6 is informative (2). For O-methyl Illinois No. 6, a high-volatile bituminous coal, values of 0.63 0.03, 1.7 0.1, and 2.6 0.1 methyl groups per 100 coal carbons were measured after three serial alkylations using 9-phenylfluorenyllithium, fluorenyllithium, and trityllithium, respectively. Although the two data sets for these bituminous coals demonstrate a similar preference for fluorenyllithium as base, and thus a significant number of C-H sites with 19 < pKa 22, they differ in that Illinois No. 6 contains important quantities of acidic C-H groups with pKa < 19 and 22 < pKa 31. Because the class of structures with 22 < pKa < 31 includes 9,10-dihydroanthracene and its analogues, we conclude that this type of six-membered hydroaromatic structure is absent, or at least below the detection limit, in PSOC 1197. 

The wireless EIT data-transmission scheme (WL-DDTS) generates an 8-bit parallel data set to be converted into the serial data by an encoder [45]. The encoded serial data are then transmitted through the wireless transmission module (Figure 30.6a) and received by the receiver module [45]. 

The numerical data published in the filed literature from the bibliographic part of the database are stored in the numerical part that is built by the database block DATASETS with the main tables TABSET and TABDAT. Both database tables are linked by the key column DSNO, which represents a serial, unique data set number. TABDAT contains the numerical data, and TABSET provides a summary of the data sets. Proceeding with the example considered above. Figure 17.3 shows two entries for reference number 5733 and substance number 2233 in TABSET. Each entry has its own data set number. In the current example there are two entries, because one series of measurement was made in the liquid state L and the other one was made at saturated liquid state SL, indicated by the column PHST for the physical state. The measured property PROP is the thermal conductivity TC. Instead of the measuring method, the method number...
