For the panel size different members are given. 8 people appears the right size for the panel.

The duration of a sample assessment depends on sniffing time, stimulus interval, panel size, simultaneous evaluation, number of dilution steps, number of blanks and number of replicates. According to the VDI Richtlinie a sample can be assessed once in 15 to 30 minutes. This assesment takes place without simultaneous evaluation and is a rather short period of time due to the inadequate stimulus interval of 15 seconds. WSL assesses a sample with the much longer interval of 1 minute. Because they use simultaneous evaluation with 3 or 4 panellists assessments can take place once in every 15 minutes. The recommended three replicates bring the total test duration up to 45 minutes. 

The panel size must be at least 6 but 8 is more suitable. 

The physical panel size used resulted in more joints between panels than would have been the case in a Portland cement pour, owing to the surface finishing with a screed and the continuous obstruction of the existing support columns. Asphalt expansion strips were placed between panels and were provided with a removable top strip which was filled with a polyurethane compound. Shrinkage of pours in this work was negligible. Shrinkage in sulfur concrete was proportional to the amount of sulfur binder used. 

A common statistical comparison, is between the test material(s) and the control material(s), to detect any differences beyond those that would occur as a consequence of random probability. In general, the smaller the size of the panel, the lower power the test will have, i.e. it will be less likely to identify genuine differences should they exist. Whether this is an issue hinges on the size of difference that the investigator would like to detect, with the optimum panel size determined by the anticipated variability of the results, which may not be known. A pragmatic approach should be taken toward panel size selection, with a sufficient number to allow some meaningful analysis, but that is not unwieldy in terms of running the study or that is prohibitively costly. 

In the main experiment, 16 dishes were evaluated using a panel consisted of 300 ordinary people with the panel size for each session being 25 to 50. Each panelist was given a test sample added MSG and a control. The panelists were asked to compare the test sample against the control, and to evaluate the flavor of the test sample checking off the point on each scale of the evaluation sheet. 

The platen size determines the maximum size of the panels that can be produced and how these can be cut into the sizes required by specific markets. The press size can easily be specified for plants serving a local market with a preferred panel size. The decision is much more complex for plants seeking to meet the requirements of diverse international markets. 

A continuous press was long an objective in the industry. There are a number of benefits of continuous pressing. From the panel perspective, the ability to determine the length of the panel after the press provides greater flexibility in panel size. Trim loss is also reduced. 

Field-driven display elements such as liquid crystals and electrophoretic display materials (of which e-Ink is the leading example) are typically ma-trixed to create large panel sizes with a manageable number of external contacts. For a 1,000,000 pixel display, for example, a matrixed panel can use 2,000 contacts 1000 rows and 1000 columns.
