Product quality prediction based on RBF optimized by firefly algorithm

With the development of information technology,a large number of product quality data in the entire manufacturing process is accumulated,but it is not explored and used effectively.The traditional product quality prediction models have many disadvantages,such as high complexity and low accuracy.To overcome the above problems,we propose an optimized data equalization method to pre-process dataset and design a simple but effective product quality prediction model:radial basis function model optimized by the firefly algorithm with Levy flight mechanism(RBFFALM).First,the new data equalization method is introduced to pre-process the dataset,which reduces the dimension of the data,removes redundant features,and improves the data distribution.Then the RBFFALFM is used to predict product quality.Comprehensive expe riments conducted on real-world product quality datasets validate that the new model RBFFALFM combining with the new data pre-processing method outperforms other previous me thods on predicting product quality.

Effects of Milling Methods on Rice Flour Properties and Rice Product Quality:A Review

High-quality rice flour is the foundation for the production of various rice-based products.Milling is an essential step in obtaining rice flour,during which significant changes occur in the physicochemical and quality characteristics of the flour.Although rice flour obtained through mainstream wet milling methods exhibits superior quality,low production efficiency and wastewater discharge limit the development of the industry.Dry milling,on the other hand,conserves water resources,but adversely affects flour performance due to excessive heat generation.As an emerging powder-making technique,semi-dry milling offers a promising solution by enhancing flour quality and reducing environmental impact.This is achieved by minimizing soaking time through hot air treatment while reducing mechanical energy consumption to reach saturated water absorption levels.However,continuous production remains a challenge.This comprehensive review summarizes the effects of various milling technologies on rice flour properties and product qualities.It also discusses key control indicators and technical considerations for rice flour processing equipment and processes.

IMPROVEMENT OF PRODUCT QUALITY AND PRODUCTION PROCESS PERFORMANCE IN JEWELLERY MANUFACTURING THROUGH “INTEGRATED CRAFTSMANSHIP”

This paper attempts to identify the loss of quality of craftsmanship intensive products. It shows that errors in production process and degradation in the jewellery pro duct quality in the (complex) transition from hand crafted silver model making to mass production are largely due to the ignorance of the importance of design——craftsmanship in production process. In fact, the design can be employed to solve the problems of the quality degradation or even as a tool to prevent error in the stages of product design, development and production. In testing this hypo thesis, production processes (from designing, model making, casting, polishing, buffing to texturing) are all examined in order to identify the root causes of product quality degradation in mass production. After the analysis, the concept of “integrated craftsmanship” is proposed to assist integration of traditional goldsmith′s and je wellery designers′ techniques in jewellery designing and making, and to change the attitudes to quality control in mass production systems. Finally, the model of “integra ted design craftsmanship” as a comprehensive design conceptual and quality organizational tool is formulated for managing and improving product quality.

The Correlation between Polydactyly Phenotype and Product Quality of Beijing Fatty Chickens

[ Objective] This study aimed to investigate differences in product quality among Beijing fatty chickens with different polydactyly phenotypes. Based on the comparative analysis of production performance, egg quality and muscle quality characteristics, the correlation between polydactyly phenotype and product quali- ty of Beijing fatty chickens was analyzed, aiming at providing the reference for development and utilization of product quality and breeding of Beijing fatty chickens. [ Method] Egg laying/meat dual-purpose type Beijing fatty chickens were selected and divided into three groups （bilateral four-toed, unilateral five-toed and bilat- eral five-toed） with four replications, 60 chickens per replications, 240 chickens per group. The production performance （weight, laying rate and egg weight）, egg quality （Haugh unit） and muscle quality （pH, water-holding capacity, Warner-Bratzler shear force, TPA, nucleotide metabolites） characteristics of Beijing fatty chickens were determined. [ Result] The weight of 120-d-old and 240-d-old bilateral five-toed Beijing fatty chickens was slightly higher than that of bilateral fourtoed and unilateral five-toed Beijing fatty chickens, with no significant difference （P 〉0.05） ; egg weight of 160-d-old bilateral five-toed Beijing fatty chickens was significantly higher than that of bilateral four-toed and unilateral five-toed individuals （ P 〈 0.05 ）. Water-holding capacity of leg muscles of bilateral five-toed Bei- jing fatty chickens was significantly superior to that of unilateral five-toed and bilateral four-toed individuals （P 〈0.05 ）. The hardness, gumminess and chewiness of leg muscles of bilateral five-toed Beijing fatty chickens were significantly lower than that of unilateral five-toed and bilateral four-toed individuals （ P 〈 0.05 ）, but the coherence and elasticity were remarkably higher compared with unilateral five-toed and bilateral four-toed individuals （ P 〈 0.05 ）. Warner-Bratzler shear force of leg muscles of bilateral five-toed Beijing fatty chickens was significantly higher than that of other individuals （ P 〈 0.05 ）. There was no significant difference in flavor substances among Beijing fatty chickens with different polydactyly phenotypes （P 〉0.05）. [ Conclusion] At early stage, the weight and egg weight of fivetoed Beijing fatty chickens were slightly superior to that of four-toed individuals. In addition, Beijing fatty chickens with different polydactyly phenotypes displayed excellent muscle quality. Overall, leg muscle quality of Beijing fatty chickens exhibited a greater correlation with polydactyly phenotype than chest muscle quality.

Normative Versus Perceptual Gap Analysis of Hotel Product Quality as a Service to Tourism in Kenya

Kenya＇s tourism business stagnated from 1991 to 2003 and only registered small but steady grew from 2004. One of the sectors that recorded poor performance as a result of the slow growth of tourism is the hotel business. Despite this slack, stakeholders in Kenya have not tried to assess the extent to which the quality of this sector may impact on destination preference. The ultimate purpose of this research was to establish the quality gap between the expected and the perceived hotel product/service quality from both the perspective of the tourists and the hotel operators in Kenya. It was motivated by the need to create parameters that can elavate the competitiveness of Kenya＇s tourism using the hotel product/service quality offer. Descriptive quantitative research design was used to establish the secondary objectives and to assess two propositions set for the study. A sample of 211 tourists and 19 hotel operators in two major tourist provinces of Kenya was used to obtain information regarding normative and perceptive hotel product/service quality. Kenya＇s only destination marketing organisation, Kenya Tourist Board （KTB） marketers were also surveyed to provide insight on Kenya＇s destination position with regard to the motivation of tourists to visit Kenya. The study established that although the attractions which make tourists come to Kenya are the unique wildlife safari, beach tourism and the natural scenery, hotel product quality and hospitality plays a vital role in motivating tourists to choose Kenya as the destination to visit. However, this study found out that while the tourists and hotel operators agree on the normative hotel product quality level, there is a significant gap between the normative quality and the perceptual quality registered by tourists who used hotel services. The study established that hotel operators only recognize quality regulatory institutions with statutory and legal authority to incriminate facilities that do not comply with laid down operational requirements such as Hotels and Restaurants Authority and the Local Authority Public Health Department. The study has proposed an integrated framework that may be utilized to build a superior national hotel product/service quality so that the economic potential of tourism is maximized in Kenya.

Mitigation of polycyclic aromatic hydrocarbons(PAHs)in roasted beef patties by cold plasma treatment and products quality evaluation

The cold plasma(CP)technique was applied to alleviate the contamination of polycyclic aromatic hydrocarbon(PAH)in this investigation.Two different CP treatments methods were implemented in the production of beef patties,to investigate their inhibition and degradation capacity on PAHs.With 5 different cooking oils and fats addition,the inhibition mechanism of in-package cold plasma(ICP)pretreatment was explored from the aspect of raw patties fatty acids composition variation.The results of principal component analysis showed that the first two principal components accounted for more than 80%of the total variation in the original data,indicating that the content of saturated fatty acids was significantly positively correlated with the formation of PAHs.ICP pretreatment inhibited the formation of PAHs by changing the composition of fatty acids,which showed that the total amount of polyunsaturated fatty acids decreased and the total amount of monounsaturated fatty acids increased.Sensory discrimination tests demonstrated there were discernable differences between 2 CP treated samples and the controls,utilization of the ICP pretreatment in meat products processing was expected to achieve satisfying eating quality.In conclusion,CP treatment degraded PAHs through stepwise ring-opening oxidation in 2 reported pathways,the toxicity of PAHs contaminated products was alleviated after CP treatment.
