If the number (N) of samples mixed together is not too large (no more than 20–30 specimens in total), theoriginal samplescan be combined by following systematic schemes (2N−1factors may be evaluated inNexperiments), or conventionaldesign matrices(e.g., Hadamard matrices) may be used to...
This approach is simpler because a common kernel function is used within the same class and is prespecified, instead of being estimated and varying locally, as in the approach of (11.45). As discussed in Chapter 7, the sensitive parameters are the size of the kernel, r, the decision ...
humans have accomplished a total of 10 lunar sampling missions. The initial nine samplings all took place during the 1960s and 1970s. Following a 44-year hiatus, Chang'e-5 retrieved 1.731 kilograms of lunar samples, opening a new chapter in cutting-edge lunar research. ...

The value obtained by dividing the sum of a set of quantities by the number of quantities in the set. For example, if there are three test scores 70, 83, and 90, the arithmetic mean of the scores is their sum (243) divided by the number of scores (3), or 81. See more atmean....

Chapter 1 Sampling and sample preparation for indoor air analysis Depending on the operation mode, air sampling can be active or passive. Active sampling requires a power source鈥攆or example, pumps or vacuum, to draw sample to a sensor/analyzer or collector. Passive sampling relies on diffusion...
When planning a research project, an epidemiologist must consider how many subjects should be studied. While factors such as available budget certainly present constraints on the maximum number of subjects that might actually be included in a study, statistical considerations are extremely important. To...
