Fruit and Vegetable Nutrition Value Assessment and Replacement Based on the Principal Component Analysis and Cluster Analysis

Utilizing principal component analysis (PCA) and cluster analysis, the standardization, dimension-reduction and de-correlation of multiple evaluation index system for fruit and vegetable nutrition are performed to assign principal component factor based on cluster analysis of loading matrix and combining with actual meaning and evaluation direction of index categories. To evaluate the richness of its nutrition according to the score of nutrition of fruit and vegetable, finally equivalent replacement suggestions are given in different seasons of vegetables & fruits according to the result of clustering. Studies show that principal component cluster method can not only carry on the reasonable classification of multivariate data effectively, but also make reasonable evaluation on the sample object, and provide powerful basis for evaluation of fruits and vegetables’ nutrition.

Comprehensive Optimization Based on Entropy Weight of Electromechanical Product Reliability Evaluation Model

The failure data of the electromechanical product satisfies a certain law that a batch of failure data usually meet a variety of distributions at the same time. As to this phenomenon, an optimization method of evaluation model of reliability which is combined with the concept of entropy was put forward in this work. In the optimization process, several empirical models and multiple evaluation indexes were proposed for selecting a best model of reliability evaluation model, and entropy weight was defined to show the importance of evaluation indexes.

Entropy weight comprehensive optimum seeking method is one of the optimization methods of reliability evaluation model. In the optimization process, several empirical models and multiple evaluation indexes were proposed for selecting a best model of reliability evaluation models. Entropy weight is defined to show the importance of evaluation indexes simultaneously. In this paper, an application case of CNC grinding machines was used to describe the optimization method in detail. The analysis result showed that the optimal reliability distribution model of CNC grinder is the mixed welbull distribution, and the method is reasonable and effective.

Research on Dichotomy Model Evaluation Method of Weighted Comprehensive Indexes

It is an important link for supporting business operations and decision-making to select optimal model from multiple models. Based on the analysis on traditional dichotomy model evaluation methods, the paper presented a kind of method to evaluate model performance that consider multiple individual evaluation indexes to compute comprehensive index ranking score. The method solves the problem of difficulty for modeling personnel when using multiple traditional evaluation indexes to evaluate a group model that different conclusion caused by different methods. The evaluation example based on the method shows that the weighted comprehensive index based evaluation method is of reference value for the optimal selection of dichotomy model.

Selection of Potential Parental Lines From Multivoltine Germplasm Stocks of Bombyx mori L.

Seventy three multivoltine mulberry silkworm genetic resources, that are diverse in nature with wide variability among the economic traits and morphologically unique were evaluated using multiple traits evaluation index and mano evaluation index. Potential accessions were identified from among the germplasm stocks conserved. Accession number BMI-043 was identified for nine specialized characters and accession number BMI-074 for eight characters and BMI-007 for six characters followed by BMI-061, BMI-001and BMI-066 for five specialized characters. Accession number BMI-043 was the top performer under mano’s evaluation index. The silkworm genetic wealth was also compare with that of the ruling popular multivoltine parental races like Pure Mysore and Nistari with many promising accessions, that can be included in the breeding programmes.

Set Pair Analysis Model Based on GIS to Evaluation for Flood Damage Risk

Evaluation to flood disaster is very difficult due to the uncertainties and complexity of multiple related evaluation indexes. In view of building SPA model and considering the standards for grades of the ambiguity of the border, the comprehensive weight was calculated and the confidence criterion was introduced, which explores a new way of flood risk evaluation based on GIS technology. Flood risk assessment map of Beijiang River basin was acquired with SPA model. Compared with a few historical large floods, the results could better reflect the actual situation, which validates the rationality of the presented model.

Identification of Potential Crossbreeds of Mulberry Silkworm, Bombyx mori L. and Their Performance Under Tropical Stress

Department of Sericulture, Sri Krishnadevaraya University, Anantapur – 515 003, Andhra Pradesh, India.(Received 02 January 2011; Accepted 19 May 2011)The performance of five newly evolved cross breedswere evaluated across seasons to understand the gen-otype and environment interactions and their stabilityunder fluctuating tropical environmental conditionsalong with control hybrids PM×CSR2 and APM1×APS8. The data was collected on eight economic traitsnamely fecundity, yield per 10,000 larvae by number,yield per 10,000 larvae by weight, survival rate, cocoonweight, cocoon shell weight, cocoon shell ratio and fil-ament length. The data was subjected for Analysis ofVariance (ANOVA) and relevant statistical methods.The performance data obtained was further subjectedfor multiple trait evaluation index method. The rankswere adjudicated based on the index values. The twohybrids viz., MSO3×APS45 and MSO1×APS12 per-formed well under diversified environmental condi-tions indicating their overall stability and superiority.These hybrids revealed highly significant (p < 0.01)improvement for the majority of the traits over thecontrol hybrids.

Selection of Superior Genotypes of Som, Persea bombycina Kost. through Bioassay

Thirty nine accessions of Som, Persea bombycina Kost. were evaluated through rearing of muga silkworm, Anthereae assamensis Helfer during two commercial seasons viz. Kotia (October-November) and Jethua (May-June) to identify the superior accessions for more silk productivity. The rearing performances on each of the som accessions were evaluated on four characters viz. effective rate of rearing (ERR), Cocoon weight, shell weight, and shell ratio percentage (SR%) by the multiple trait evaluation index (EI) method. During Kotia crop, fourteen accessions showed average EI values of &gt;50 (ranging from 50.22 to 62.37) and during Jethua crop, twenty accessions manifested average EI values of &gt;50 (ranging from 50.12 to 67.55). It was found that ten accessions viz. PT-11, PT-16, PT-17, PT-27, PT-28, PT-29, PT-37, PT-38, PT-34 and PT-04 exhibited average EI values of &gt;50 in both the rearing seasons thereby indicating the superiority of these accessions to the other accessions.

Identification of high yielding oak tasar silkworm hybrids

The rearing performances of twelve selected oak tasar silkworm hybrids were estimated based on the multiple trait evaluation index (E.I.) method in two trial rearing for the eight yield contributing traits, viz., fecundity, hatching percentage, cocoon yield per disease free laying, effective rate of rearing (ERR), cocoon weight, shell weight, shell ratio, filament length. In the first trial rearing, the hybrid PRP12 x Blue recorded the highest E.I. value (54.77), followed by B6 x PRP5 (54.55), BY1 x PRP5 (53.72), BY1 x PRP12 (52.77), PRP3 x BY1 (51.40) and BY1 x Blue (50.31). In the second trial rearing, B6 x PRP5 manifested the highest E.I. value (64.11) followed by BY1 x PRP12 (64.07), BY1 x Blue (55.21) and PRP12 x Blue (55.21). It is observed that the four hybrids, viz., PRP12 x Blue, B6 x PRP5, BY1 x Blue and BY1 x PRP12 exhibited consistent high E.I. values of above 50 in both the trial rearing. Therefore, these four hybrids can be used in future breeding program and commercial production of cocoons.
