| 1 | Heat Transfer in Steelmaking Ladle显示文摘The heat transfer in a steelmaking ladle was studied. The evaluation of heat transfer of the steel was performed by measuring steel temperature in points including all refining steel process. In the ladle, the temperatures in the refractories and the shell were also measured. To evaluate the thermal profile between the hot and cold faces of the ladle in the slag line position, an experiment which shows the importance of thermal contact resistance was carried out. Higher heat losses in the tapping and the vacuum were verified. The temperature measurements of the ladle indicate distinct thermal profiles in each stage of steel refining. Moreover, as each stage of the process depends on the previous one, the complexity of the ladle thermal control is incremental. So a complete model of heat losses in the ladle is complex. | André Zimmer lvaro Niedersberg Correia Lima Rafael Mello Trommer Saulo Roca Bragana Carlos Pérez Bergmann | 2008 | Journal of Iron and Steel Research(International)2008，15，3： | 4 |
| 2 | Circulating leptin and its muscle gene expression in Nellore cattle with divergent feed efficiency显示文摘Background: Leptin has a strong relation to important traits in animal production, such as carcass composition,feed intake, and reproduction. It is mainly produced by adipose cells and acts predominantly in the hypothalamus.In this study, circulating leptin and its gene expression in muscle were evaluated in two groups of young Nellore bulls with divergent feed efficiency. Individual dry matter intake(DMI) and average daily gain(ADG) of 98 Nellore bulls were evaluated in feedlot for 70 d to determinate the residual feed intake(RFI) and select 20 animals for the high feed efficient(LRFI) and 20 for the low feed efficient(HRFI) groups. Blood samples were collected on d 56 and at slaughter(80 d) to determine circulating plasma leptin. Samples of Longissimus dorsi were taken at slaughter for leptin gene expression levels.Results: DMI and RFI were different between groups and LRFI animals showed less back fat and rump fat thickness,as well as less pelvic and kidney fat weight. Circulating leptin increased over time in all animals. Plasma leptin was greater in LRFI on 56 d and at slaughter(P = 0.0049). Gene expression of leptin were greater in LRFI animals(P = 0.0022) in accordance with the plasma levels. The animals of the LRFI group were leaner, ate less, and had more circulating leptin and its gene expression.Conclusion: These findings demonstrated that leptin plays its physiological role in young Nellore bulls, probably controlling food intake because feed efficient animals have more leptin and lower residual feed intake. | Lúcio Flávio Macedo Mota Cristina Moreira Bonafé Pamela Almeida Alexandre Miguel Henrique Santana Francisco JoséNovais Erika Toriyama Aldrin Vieira Pires Saulo da Luz Silva Paulo Roberto Leme JoséBento Sterman Ferraz Heidge Fukumasu | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 3 |
| 3 | Multi-target prediction of wheat flour quality parameters with near infrared spectroscopy显示文摘Near Infrared(NIR)spectroscopy is an analytical technology widely used for the nondestructive characterisation of organic samples,considering both qualitative and quantitative attributes.In the present study,the combination of Multi-target(MT)prediction approaches and Machine Learning algorithms has been evaluated as an effective strategy to improve prediction performances of NIR data from wheat flour samples.Three different Multi-target approaches have been tested:Multi-target Regressor Stacking(MTRS),Ensemble of Regressor Chains(ERC)and Deep Structure for Tracking Asynchronous Regressor Stack(DSTARS).Each one of these techniques has been tested with different regression methods:Support Vector Machine(SVM),Random Forest(RF)and Linear Regression(LR),on a dataset composed of NIR spectra of bread wheat flours for the prediction of qualityrelated parameters.By combining all MT techniques and predictors,we obtained an improvement up to 7%in predictive performance,compared with the corresponding Single-target(ST)approaches.The results support the potential advantage of MT techniques over ST techniques for analysing NIR spectra. | Sylvio Barbon Junior Saulo Martielo Mastelini Ana Paula ACBarbon Douglas Fernandes Barbin Rosalba Calvini Jessica Fernandes Lopes Alessandro Ulrici | 2020 | Information Processing in Agriculture2020，7，2： | 2 |
| 4 | Aerodynamic Effects Compensation on Multi-Rotor UAVs Based on a Neural Network Control Allocation Approach显示文摘This paper shows that the aerodynamic effects can be compensated in a quadrotor system by means of a control allocation approach using neural networks.Thus,the system performance can be improved by replacing the classic allocation matrix,without using the aerodynamic inflow equations directly.The network training is performed offline,which requires low computational power.The target system is a Parrot MAMBO drone whose flight control is composed of PD-PID controllers followed by the proposed neural network control allocation algorithm.Such a quadrotor is particularly susceptible to the aerodynamics effects of interest to this work,because of its small size.We compared the mechanical torques commanded by the flight controller,i.e.,the control input,to those actually generated by the actuators and established at the aircraft.It was observed that the proposed neural network was able to closely match them,while the classic allocation matrix could not achieve that.The allocation error was also determined in both cases.Furthermore,the closed-loop performance also improved with the use of the proposed neural network control allocation,as well as the quality of the thrust and torque signals,in which we perceived a much less noisy behavior. | Sarah P.Madruga Augusto H.B.M.Tavares Saulo O.D.Luiz Tiago P.do Nascimento Antonio Marcus N.Lima | 2022 | IEEE/CAA Journal of Automatica Sinica2022，9，2： | 2 |
