Various other applications of ANN in meat science and technology In addition to the mentioned subjects of interest for ANN application in meat science there are various other applications related to meat technology issues (Table 4). These involve identification of animal species in ground meat mixtures (Winquist et al., 1993) or fat tissue (Beattie et al., 2007), recognition of animal origin (distinction between Iberian and Duroc OBJECTIVE SAMPLE INPUT DATA RESULTS REFERENCE Species recognition Ground beef, pork, n=20 Electronic nose Successful Winquist et al., 1993 Visual guidance of evisceration Pig carcasses Computer vision Efficient ANN based system Christensen et al., 1996 Lean tissue extraction (image segmentation) Bovine LD n=60 Computer vision (hybrid image) Better efficiency and robustness of ANN based system Hwang et al., 1997 Fermentation monitoring Sausage Electronic nose Lowest error in case of ANN compared to regression Eklöv et al., 1998 Estimation of meat internal T Cooked chicken meat IR imaging Great potential for monitoring of meat doneness (error of ±1°C) Ibarra et al., 2000 Determination of RN - phenotype Pig n=96 NIR spectroscopy 96% correctness Josell et al., 2000 Identification of feeding and ripening time Pig; dry- cured ham Electronic nose Best prediction for N at 250°C; misclassified hams ≈8% Santos et al., 2004 Species recognition on adipose tissue Lamb, beef chicken,pork n=255 Raman spectroscopy >98% correctness Beattie et al., 2007 P Cooking shrinkage Bovine TB n=25 Computer vision technique r=0.52-0.75 Zheng et al., 2007 Walk-through weighing Pigs Machine vision relative error ≈3% Wang et al., 2008 Differentiation of Iberian and Duroc Pigs n=30 VIS-NIR spectroscopy >95% correctness del Moral et al., 2009 LD – longissimus dorsi; TB – triceps brachii; R 2 – coefficient of determination; r – correlation coefficient; P – prediction; C – classification; VIS – visible; NIR – near infrared; IR - infrared.

Again, in the majority of studies, ANN approach was an instrument to deal with the complex output signal of novel technologies applied. Again, based on the literature reports, supervised learning strategy of ANN (BP-ANN, RBF) was applied in the majority of studies. There were also a few studies where unsupervised learning has been tested (Winquist et al., 1993; Beattie et al., 2007). A bibliographic overview given in Table 4 demonstrates the efficiency and successful classification rate of ANN based systems. 8. Conclusions and future perspectives The existing research work of ANN application in meat production and technology provided many useful results for its application, the majority of them in association with novel technologies. Among interesting ideas that have not been encountered in the literature review is the combination of ANN with bio-sensing technology. ANN shows great potential for carcass and meat (product) quality evaluation and monitoring under industrial conditions or bacterial growth and shelf-life estimation. However, the potentially interesting relevance of ANN, for which the literature information is scarce, is its application for meat authenticity or meat (product) quality forecast based on the information from rearing phase. Overall the presented applications are relatively new and the full potential has not yet been discovered. 9. References Argyri, A. A., Panagou, E. Z., Tarantilis, P. A., Polysiou, M. & Nychas, G. J.

Introduction 1.1 Background and significance of the research Currently, the world's fuel vehicle is growing by the rate of 30 million per year. It is estimated that the total amount of the world's fuel vehicle for the whole year will reach one billion. The sharp increase demand in oil’s resources, further aggravate the shortage of oil resources in the world [1-2]. Fuel vehicle exhaust emission is the main source of urban air pollution today, and the negative impact on the environment is enormous. Environment is closely related to the survival and development of human society. In the case of the energy shortage and environmental protection urgent need to improve, governments invest enormous human and material resources to seek new solutions. This is also bringing the development of electric vehicle [3-6]. As power source and energy storage of HEV, battery is the main factors of impacting on the driving range and driving performance of HEV [7-8]. At present, the most important question is the capacity and battery life issues with HEV application. Only estimate SOC as accurate as possible can we ensure the realization of fast charging and balanced strategy. The purpose of that is to prevent over charge or discharge from damaging battery, and improve battery life. This also has practical significance in increasing battery safety and reducing the battery cost [9]. How accurate tracking of the battery SOC, has been the nickel-hydrogen battery’s researchers concerned about putting in a lot of energy to study. Currently, it is very popular to estimate the SOC with Ampere hours (Ah) algorithm as this method is easy to apply in HEV. The residual capacity is calculated by initial capacity minus capacity discharged. But Ah algorithm has two shortcomings. First, it is impossible to forecast the initial SOC. Second, the accumulated error cannot be ignored with the test time growing [10]. The researchers also used a new method that the battery working conditions will be divided into [...]...
