Asian rice is an important grain, not only in its homeland but in many areas of the world. Preliminary studies suggested that phytolith analysis, the identification of opaline silica bodies, provided a reliable way of identifying rice, especially in situations where preservation of charred botanical remains was poor. Results of this follow-up study...

Seventeen morphological and physiological characteristics of three Avena barbata L. populations from Israel were measured in order to define possible combinations explaining adaptation of these populations to different precipitation, temperature and altitude regimes. Five genotypes from each A. barbata populations were collected from Ashqelon (31°6...

A frequent variety of typology is that which results when a given population is classified simultaneously by several criteria, the categories of each criterion being ordered in a sense common to all the criteria. Such simultaneous orderings automatically define a partial order typology.The empirical problem is to ascertain the dimensionality and th...

In order to integrate the outcomes of interspecific somatic fusion experiments in breeding schemes, it is important to understand factors involved in the variability observed among regenerated plants. With such a purpose in mind, a population of Solanum commersonii (+) S. tuberosum somatic hybrids was examined by means of discriminant and cluster a...

Using neural networks, discriminant analysis and regression, a model for annoyance assessment of vehicle interior noise situations is empirically estimated. The data base for the estimate consists of 12 different vehicle-speed pairs for which 24 subjective assessments are available. Descriptive statistical parameters of the dataset are presented. T...
A methodology for analyzing changes in Total Primary Energy Consumption (TPC) and the ratio of Total Primary to Total Final Energy Consumption (TFC) is presented using the principles of factor analysis. It allows one to separate influences of trade with transformation products, changes in structure of energy carriers, and changes in transformation ...
The aim of the present paper is to test and compare some mathematical discrimination or pattern recognition methods in order to identify one among three air pollution sources.The basic material in this work are : - the standard gas chromatography/mass spectrometry analysis with concentrations values for different chemical compounds observed at abou...
The mainstays of the clinical diagnosis of melanoma are asymmetry, border irregularity, color variegation, and a diameter >6 mm, and any major progress in diagnostic accuracy will probably be related to the development of additional criteria. Such independent criteria might arise from the study of the geometry of the tumour surface, because this qu...

Many patients with Williams syndrome (WS) are not diagnosed until they are old enough to demonstrate the characteristic personality and facial changes. A number of these changes are quite subtle and none of them is present in all affected individuals. The cause of WS remains obscure and consequently, there are no cytogenetic, biochemical, or molecu...

A multiple regression/discriminant analysis of positron emission tomographic cerebral metabolic (rCMRglc) data in 10 obsessive-compulsive disorder (OCD) patients before and during pharmacotherapy was carried out to see if rCMRglc interdependencies distinguished OCD patients from controls. Before therapy, a discriminant function reflecting parietal,...
