Grid plans

Relatively homogeneous distribution Rectangular or bottle rack grid 

Centered contamination Polar grid or stratified rectangular or bottle rack grid 

Linear contamination Linear grid, several diagonals (sometimes in zig zag manner, e.g. in the shape of capital letters N, W, or X) 

If the contamination took place in one dimension only, as for example in rivers or groundwater streams, a simple linear or diagonal grid should be selected. 

A practical method for the investigation of two-dimensional contamination, which includes the use of grid plans and easy-to-handle composite samples, is described in the literature [ASSMUS et al., 1985] under the name strip sampling.

Tab. 4-3 demonstrates the relationship between the assumed pollutant distribution and the grid plan which should be used for sampling. 

Fig. 4-7 shows principal examples of the various types of rigid grid plans. 

To answer this question higher expenditure is necessary. A grid plan has to be selected which guarantees the detection of existing maximum values in order to obtain information on the distribution which enables the reliable assessment of such extreme values. Subareas with higher loads must be assessed with a sufficient accuracy also. 

Soil core samples are collected at several depth intervals to approximately 50 cm depth using for example a 25 x 25 cm sampling grid plan. 

In the 1780s, Thomas Jefferson not only suggested the ten by ten mile grid plan, but also proposed requirements for the admission of new states in the western territory. For example, he suggested that a territory should be eligible for statehood when its population exceeded 20,000. He also proposed boundaries for fourteen... 

It is easy for a TSO to recognize the need for simulation tools that can calculate the risk levels for different time horizons. Such a simulation tool should be useful for a TSO in online operations, day-ahead and intraday short-term grid planning ... 

Example of a systematic sampling plan for collecting samples from a lake. Each solid dot represents a sample collected from within the sampling grid. 

There has been considerable and continuing investment in e-science and Grid-based computing around the world. Of particular interest for protein crystallography is the e-HTPX project funded by the UK research councils (http //www.e-htpx.ac.uk). The aim of e-HTPX is to unify the procedures of protein structure determination into a single all-encompassing interface from which users can initiate, plan, direct, and document their experiment either locally or remotely from a desktop computer. 

In the USA, some 150 new coal-fired power stations are planned. In China, two 500 MW coal-fired power plants are currently starting up every week, and each year the country s coal-fired power generating capacity increases by the equivalent of about half the entire German grid (The Economist, 2007). 

A demonstration of a MCFC power plant at an automobile manufacturing plant site in Tuscaloosa, Alabama is planned for the first quarter of 2001. The 250 kilowatt system will feed the production facility power distribution grid. Four companies are teaming up to support the program Southern Company, Alabama Municipal Electric Authority (AMEA), Fuel Cell Energy, and Mercedes Benz U.S. International, Inc. (MBUSI). The system will employ FCE s stack and MTU s power plant design, called the Hot Module. ... 

The relative humidity at each grid point shall be within the specihed levels and tolerance limits indicated for each room in the validation master plan. If these levels are attained, the system is accepted.
