Collection of appropriate qualitative and quantitative data is necessary for proper management and planning. Used the suitable inventory methods is necessary and accuracy of sampling methods dependent the inventory net and number of sample point. Nearest neighbor sampling method is a one of distance methods and calculated by three equations (Byth and Riple, 1980; Cotam and Curtis, 1956 and Cota...

A new distance-based estimator for forest regeneration assessment, the mean distance method, was developed by combining ideas and techniques from the wandering quarter method, T-square sampling and the random pairs method. The performance of the mean distance method was compared to conventional 4.05 square meter plot sampling through simulation analysis on 405 square meter blocks of a field sur...

" Simple Random Sampling (SRS). Simple random sampling (SRS) is the primary sampling technique, which also serves as the basis for other techniques. Simple random sampling occurs when a sample size of n (for example, selected subset of eggs) from a population of size N (for example, total number of eggs produced on a farm on a given day) is taken in such a way that every possible sample of size...

The performance of a networked control system (NCS) is affected directly and indirectly by time delays generated in network communication. This paper addresses these time delays, their effects on system performance, and the measures taken in an NCS design. For a time delay which is random but less than one sampling interval T, we model the system as a time-invariant control system with constant...

a. Follow-ups to Session 13 • Comment on the codes from Session 13. The codes used in Session 13 use various " tricks " or shortcuts to make them more compact. In general, I don't recommend coding this way (so these codes should be rewritten!). For example, the choice of energy units is exploited so that energies are integers and therefore can be used as array indices. But if we added an extern...

SIMULATING DEPENDENT BINARY DATA WITH RANDOM EFFECTS. Aobo Wang, Roy T. Sabo, Department of Biostatistics, Virginia Commonwealth University, Richmond, Virginia 23298-0032. Dependent binary data can be simply simulated using the multinomial sampling method. We extend this method to simulate dependent binary data with clustered random effect structures. Several distributions are considered for co...

Background. In addition to beneficial traditional practices, there are around 140 harmful traditional practices affecting mothers and children in almost all ethnic groups of Ethiopia. Therefore this study might give a clue about their practice and associated factors. The objective of this study was to assess magnitude of harmful traditional practices among children less than 5 years of age in A...

owing to the importance and necessity of identifying soil properties in arid rangeland management, and the variableeffects of different kinds of herbivores on soil, this study compares some of the physical and chemical properties ofsoil between two regions experiencing livestock and wildlife grazing in the desert rangelands of kalmand-bahadoranin yazd province. the key areas in two regions expe...
