The technique of "piecewise fitting of model" is demonstrated in construction of volume table for Eucalyptus from data of block and strip plantations from Punjab. This technique has been found to yield more accurate results as shown by the reduction in average error of estimates.- Volume Tables for Pinus kesiya

Volume Tables for Pinus kesiya were prepared by using data from Orissa, U.P., West Bengal and Tamil Nadu. The best fit was obtained by using the model V=a + bD2H for general volume tables. Local volume tables were also prepared for Koraput and Balliguda Divisions of Orissa State separately as the sites were found to be significantly different. The model √ V =a+bD was found most appropriate for preparing local volume tables.- Yield of Heartwood in Acacia catechu (Khair) for Use in Katha Manufacture

Tbe heartwood of Acacia catechu (khair) tree is used in manufacture of katha. The period of harvest to meet the needs of industry will thus depend upon the time of maximum heartwood production. Tree model to simulate growth and yield of khair has been developed to predict yields obtainable under different site conditions. It also provides information to initial spacing for planting to obtain the most from the site.- Total Tree Volume Table for Pterocarpus dalbergioides (Andaman Padauk)

Eucalyptus hybrid is mainly supplied to the Pulp and Paper Industry. To know its solid volume correspondiug to stacked volume, measured in the field, tables have been prepared. Data of Bijnor Plantation Division has been used. The regression equation of type V= a+b S where V=solid volume, S= stacked volume and a and b are Constants, was found to fit the data and was utilized.- Tree Volume Tables for Eucalyptus grandis

Large scale plantations of Eucalyplus grandis have been raised in the high lands of Kerala and in the Nilgiris in Tamilnadu. The wood from these plantations will be mainly used for the production of pulp. Previous tables (A.N. Chaturvedi, Ind. For. Ree., Vol 12, No. 17) were based on the regression of volume on the variable D-H (D=diatmeter, and H=height of a tree). These tables were based on a measurement of 149 trees. The determination coefficient was quite high for this regression (0.99). Regression of, √V was further fitted on variable D (R2=O.97). A new analysis has been attempted, as (i) the number of trees measured now is 233 and the data naturally covers more trees of higher age classes and (ii) it was not considered worthwhile to restrict the fitting of regression to one variable only.- Chemical Pulps for Writing and Printing Papers from Ringal (Arundinaria Sp.)

Laboratory experiments on the production of chemical pulps from ringal (Arundinaria sp.) for production of writing and printing papers by sulphate process are described. The average fibre length of pulp was 1.01 mm and average fibre diameter was 11 microns. Easy bleaching pulps in satisfactory yields could be prepared under suitable conditions of digestion.- Basal Area - Volume Relations for Eucalyptus grandis Crops

Large scale plantations are being raised in the country under the Five year plans. The main point of interest at any time is 'What is the volume of the crop?'. The direct measurement of volume is tedious and felling of sample trees may not be always possible. However two parameters viz. basal area (BA) of the crop and crop height (H) can be easily and quickly estimated. In the present study for E. grandis crops regressions of crop volume (both with and without bark) on the variable BA × H have shown very high determination coefficients. Tables have been given to estimate volume based on these parameters. It has been noticed that, although at 5% level of probability, the regression is independent of quality classes, at a lower level of probability it may become dependent on quality class. However, when the number per hectare (N) another easily estimable parameter-is added as an extra variable in the regression equation, there is not only considerable reduction in the residual sum of squares, the regression becomes definitely more independent of the quality. The regression equations so developed for volume (both outside & inside bark) are given and two tables are given for No.=800/ha and 1600/ha; other tables are not given but can be formed by using the equations.- A New Parallel Prime Multi Algorithm for Association Rule Mining

This paper describes a new parallel PrimeMulti algorithm for association rule mining. PrimeMulti algorithm addresses the shortcoming of previously proposed parallel buddy prima algorithm. New efficient algorithm for load balancing is also proposed in this paper. New algorithm divide transaction database equally according to the transaction length to the processors. In the Parallel PrimeMulti algorithm transaction database is represented by prime number. Less memory is requires as each transaction is replaced with the product of the equivalent prime numbers of their items. Parallel PrimeMulti algorithm works on top down as well as bottom up approach. The proposed algorithm for parallel frequent itemset mining and load balancing reduces the time and data complexity and divide transactional database efficiently for good load balancing among the processor.Keywords

Association rule mining and classification are two important techniques of data mining in knowledge discovery process. Integration of these two has produced class association rule mining or associative classification techniques, which in many cases have shown better classification accuracy than conventional classifiers. Motivated by this study we have explored and applied the combinatorial mathematics in class association rule mining in this paper. Our algorithm is based on producing combinations of itemsets including classes using combinatorial mathematics and subsequently finds an associative classifier. In our approach, experimental results have given accuracy, near to other popular classification methods.Keywords
