Tri-axial accelerometry allows to determine parental food provisioning behaviour in a marine bird

The study of parental food provisioning is essential for understanding the breeding ecology of birds.We conducted the first study using accelerometry to detect food provisioning in birds,using Support Vector Machine(SVM)models to identify when adults feed chicks of three different age classes.Accelerometers were attached to the head of adult female Imperial Shags(Leucocarbo atriceps),and various attributes derived from the acceleration signals were used to train SVM models for each chick age class.Model performance improved with chick age class,with SVM models achieving high overall accuracy(>88%)and highest sensitivity in older chick categories(>91%).However,precision values,especially for younger chicks,remained relatively low(between 26%and 45%).The application of a time filter based on the minimum duration of the observed food provisioning behaviours for each chick age category,improved model performance by reducing false provisioning behaviours,particularly in the model for older chicks,which showed the highest precision(72.4%).This study highlights the effectiveness of accelerometry and machine learning in studying parental food provisioning in birds,providing a rapid and accurate data collection method to complement traditional techniques.The described methodology can be applied to any bird species that exhibits distinctive movements while feeding its offspring and has suitable characteristics for attaching an accelerometer to the body part that best captures this movement.Finally,it is hoped that the results of this study will contribute to future research on key questions in parental investment theory and reproductive strategies in birds.

Life cycle inventory analysis of CO_2 and SO_2 emission of imperial smelting process for Pb-Zn smelter

Based on the principle of life cycle assessment, CO2 and SO2 emission of Imperial Smelting Process in a certain zinc-lead smelter was analyzed by life cycle inventory method. According to the system expansion and substitution method, the environmental impacts of co-products were allocated among the main products of zinc, lead and sulfuric acid. The related impacts were assessed by use of Global Warming Potential （GWP） and Acidification Potential （ACP）. The results show that the GWP index from 1998 to 2000 is 11.53, 11.65, 10.93 tCO2-eq/tZn respectively, the ACP index decreases from 14.88 kgSO2-eq/tZn in 1998 to 10.99 kgSO2-eq/tZn in 2000. Power and electricity generation, followed by smelting and zinc distillation, are mainly responsible for GWP. Sintering individually affects ACP. Reduction in greenhouse gas emissions of the ISP may come from energy conservation measures rather than from technological developments. And recycling more secondary Pb and Zn materials effectively treated by ISP, and reducing the amount of primary metal are the main ways to put SO2 emission under control.

Intelligent predictive model of ventilating capacity of imperial smelt furnace

In order to know the ventilating capacity of imperial smelt furnace(ISF), and increase the output of plumbum, an intelligent modeling method based on gray theory and artificial neural networks(ANN) is proposed, in which the weight values in the integrated model can be adjusted automatically. An intelligent predictive model of the ventilating capacity of the ISF is established and analyzed by the method. The simulation results and industrial applications demonstrate that the predictive model is close to the real plant, the relative predictive error is 0.72%, which is 50% less than the single model, leading to a notable increase of the output of plumbum.

A Case Study of Language Policies in Hong Kong

Hong Kong belongs to China. However, Hong Kong has been a colony of the British Empire for 154 years and 11 months and it has been under Japan rule for three years and eight years. Hong Kong returned to China in 1997. Its special history has significant influence on the language development in Hong Kong. During the period of British Empire, the popularity of Christianity, the commercial usefulness of English and high prestige in the society have resulted in the widely spread of English.In addition, English-medium education is in a relatively high state under the colonial regime while Chinese-medium education to some extent is not emphasized. The government has ruled that if parents would like their children to be educated in a good government school, they need to receive English-medium education. Consequently, the majority of parents would like their children to be educated by English. Apart from that, English has a legal status as an official language during British Colonialism period in Hong Kong. Lastly, some scholars supported the existence of a new English variety in Hong Kong(Hong Kong English), but others do not believe that. The requirements of language policies and the process of language spread in Hong Kong could be explained using some theories such as‘linguistic imperialism',‘Kachru's concentric circles' and‘Schneider's five stages'. For instance, from Kachru's perspective, the development of English in Hong Kong could be placed at the beginning of the third stage.It will firstly demonstrate some primary language policies in Hong Kong before its‘Handover'to China. And then, it will show several significant language spread theories and focus on relating them to the requirements of language policies and the process of language spread in Hong Kong.

Landscape alteration affects the demography of an endangered avian predator by reducing the habitat quality

Habitat transformation is identified as major threat to biodiversity loss globally,affecting threatened raptors.Changes in land use can alter the abundance and distribution of birds of prey by affecting habitat availability and quality.In this study,we used multivariate analyses to investigate the effect of habitat alteration on the demography of a declining Eastern Imperial Eagle(Aqufla heliaca),making assumptions for future population trajectories.We used the Generalized Linear Mixed Models with Poisson distribution and Log link function,searching a relationship between the demographic parameters and the landscape structure and possible effects of fragmentation.In our study area,habitat change affected dramatically permanent grasslands,shrinking their availability.As we expected,the share of grasslands in eagles’territories significantly affected occupancy rate,but not productivity and breeding frequency.We found that occupancy rate decreased significantly,while productivity and breeding frequency showed no trend.Modeling the effect of habitat alteration on Eastern Imperial Eagle demography,we found out that territory quality was a more powerful factor driving the response of a top predator to the alteration of favorite foraging habitats.Only the habitat quality in source territories had a significant positive effect on eagle productivity.We found that simple rules to predict adverse agricultural impact on territory abandonment or breeding productivity of a top predator were not reliable.Our results could be used for planning conservation of other large territorial raptors,facing the same type of threat.

On-line forecasting model for zinc output based on self-tuning support vector regression and its application

An on-line forecasting model based on self-tuning support vectors regression for zinc output was put forward to maximize zinc output by adjusting operational parameters in the process of imperial smelting furnace. In this model, the mathematical model of support vector regression was converted into the same format as support vector machine for classification. Then a simplified sequential minimal optimization for classification was applied to train the regression coefficient vector α- α* and threshold b. Sequentially penalty parameter C was tuned dynamically through forecasting result during the training process. Finally, an on-line forecasting algorithm for zinc output was proposed. The simulation result shows that in spite of a relatively small industrial data set, the effective error is less than 10% with a remarkable performance of real time. The model was applied to the optimization operation and fault diagnosis system for imperial smelting furnace.
