The paper discusses the major reasons for the drop in food production in Java during the period of Japanese occupation. Statistics on the acreage and production of six main foodstuff during the year 1940-1946 showed significant reduction of food production in Java after 1942. This reduction is explained as the result of several physical limitation to the production and marketing process of foodstuff. The article explicate several other factors that added to the principal reason for the fall in food production after 1942. The principal reason is laid on the control system of the Javanese rice economy that had reduced the real purchasing price of grain. This resulted in little incentive for peasants to pursue surplus production outside of their household subsistence needs. The only incentive was a negative incentive of forced deliveries.

In this paper, the real-time EtherCAT technology is introduced in detail, which including operating principle, communication protocol and the superiority performance of EtherCAT i.e. synchronicity, simultaneousness and high speed. To show how to design a slave system that considering the characteristics of application, the method of developing systems based no EtherCAT technology are proposed. Finally, a data acquisition system based on EtherCAT technology is designed. Application of EtherCAT technology can improve the real-time characteristics of data communication in wind power system.

Surplus Production

Globalisation is a key pressure affecting the current and future use of the rangelands of Australia. While primary producers often perceive an insatiable demand for food as a guarantee of business success, declining population growth rates and high levels of productivity improvement in world food production are reducing the importance of food and fibre from the rangelands. This, combined with significant changes in consumer demands, is driving rangeland producers to meet market specifications for quality, safety, animal welfare and sustainability. Sustainability is a particular challenge with the rangelands certain to be affected by global warming and the politics and strategies required to reduce greenhouse gas emissions. Currently the rangelands produce a higher proportion of greenhouse gases compared with their contribution to the economy. However, they also provide an opportunity for carbon sequestration. While international trade liberalisation has been of advantage to the grazing industries in the rangelands, increased global awareness of the Australian rangelands, facilitated by the communications revolution, is encouraging alternative uses including tourism, existence value and other conservation and biodiversity management uses. The growing concept of multi-functionality will also impact on the rangelands as international government programmes continue to encourage non-commercial, surplus production of food. These influences are forcing major changes in the way land is used and what it produces.

Real Purchasing

The traditional marketing methodologies (e.g., television commercials and newspaper advertisements) may be unsuccessful at selling products because they do not robustly stimulate the consumers to purchase a particular product. Such conventional marketing methods attempt to determine the attitude of the consumers toward a product, which may not represent the real behavior at the point of purchase. It is likely that the marketers misunderstand the consumer behavior because the predicted attitude does not always reflect the real purchasing behaviors of the consumers. This research study was aimed at bridging the gap between traditional market research, which relies on explicit consumer responses, and neuromarketing research, which reflects the implicit consumer responses. The EEG-based preference recognition in neuromarketing was extensively reviewed. Another gap in neuromarketing research is the lack of extensive data-mining approaches for the prediction and classification of the consumer preferences. Therefore, in this work, a deep-learning approach is adopted to detect the consumer preferences by using EEG signals from the DEAP dataset by considering the power spectral density and valence features. The results demonstrated that, although the proposed deep-learning exhibits a higher accuracy, recall, and precision compared with the k-nearest neighbor and support vector machine algorithms, random forest reaches similar results to deep learning on the same dataset.

It introduces a design of the control system for rehabilitation horse based on MCU STC89C52. The system’s control core is an 8-bit MCU STC89C52. First, the user input commands through the keyboard, then send commands to the DA conversion chip PCF8591 which can achieve the digital signal to analog signal output after dealing with MCU. Finally, PCF8591 send analog signal to the speed controller of DC motor in order to control the DC motor’s speed. Meanwhile, it builds a human-machine interface (HMI) to display the real-time speed of the horse through LCD.
