A STATISTICAL TEST FOR RANKING DATA FROM PARTIALLY BALANCED INCOMPLETE BLOCK DESIGNS
Journal of Sensory Studies, 2011ABSTRACTThe analysis of partially balanced incomplete block (PBIB) ranked data is discussed. Two examples are given to illustrate two alternative approaches. Analysis of PBIB ranking data is not covered in any of the standard sensory evaluation texts and this expository note is meant to help fill this gap.

Design and statistical analysis of a new chaos block cipher for WSN
2010 IEEE International Conference on Information Theory and Information Security, 2010In this paper, a chaotic block cipher based on chaos box is proposed for WSN. First, the pors and cons of WSN existing encryption algorithm is analysed. Then, a new encryption algorithm for WSN is introduced. Finally, conclusion is made by comparing with RC5 and RC6 at statistical performance. Data shows this encryption scheme has good performance.

23. Statistical characteristics of event related and block design datasets
Clinical Neurophysiology, 2014Introduction In this work we characterize functional magnetic resonance imaging (fMRI) data from event related and block design studies with typical values of several parameters. We use signal to noise ratio (SNR), percent signal change (PSC) and statistical parametric maps, estimated by SPM8 toolbox (beta, con and t-statistic maps).

Abstract We evaluated the use of a Latin Square design for assessing the performance of bycatch reduction devices (BRDs). We wanted to ensure the most precise result possible given limited resources, high variability and the need to detect small differences.

ABSTRACTThe usual Durbin analysis for ranked data obtained from a balanced incomplete block design is extended to allow for (1) dispersion effects, (2) a predetermined ordering of products and (3) more general trends. An application to paired comparison data is given. Calculation of pâvalues via Monte Carlo simulation is suggested.

Abstract The purpose of this paper is to derive minimal sufficient statistics for the balanced incomplete block design and the group divisible partially balanced incomplete block design when the Eisenhart Model III (mixed model) is assumed. The results are identical to Hultquist and Graybill's (1965) and Hirotsu's (1965) for the same model without ...

Design and statistical analysis of a new chaotic block cipher for Wireless Sensor Networks
Communications in Nonlinear Science and Numerical Simulation, 2012Abstract Security issue is a vital and active topic in the research of Wireless Sensor Networks (WSN). After surveying the existing encryption algorithms for WSN briefly, we propose a new chaotic block cipher for WSN and then compare the performance of this cipher with those of RC5 and RC6 block ciphers.

On the Use of a Friedman-Type Statistic in Balanced and Unbalanced Block Designs
Technometrics, 1981Distribution-free tests and multiple comparison procedures are considered for randomized block designs. A general Friedman-type statistic is defined that is usable in almost any block design with arbitrary missing data structure. For balanced incomplete block designs a multiple comparison procedure and exact tables are given for a statistic equivalent ...
