This paper proposes a framework to design an automatic control system of a plant factory based on artificial neural network (ANN) and presents the simulation results of the proposed system. The proposed system can collect information of crop cultivation environment and monitor it in real-time by using various environment sensors. Installed wire or wireless sensor nodes, based on the sensor netw...

Bit Error Rate (BER) is a principle measure of data transmission link performance. BER tester (BERT) consists of a Pattern Generator and an Analyzer that can be set to the same pattern. The payload data transmitted from the spacecraft consists of one, two or three channels per carrier based on the modulation scheme. The traditional equipments can do BER analysis for only one channel at a time. ...

We redefine an address, which is location information within the Internet, as a locator, and propose a HANA protocol, which hierarchically and automatically allocates and assigns locators to network equipments. From the Internet core to stub networks, HANA can reduce manual configurations of network equipments related to locators as possible, and then can reduce network management costs. Even i...

Knowledge accumulation in the richer countries provides them with comparative advantages in higher productivity products. The countries that import the higher productivity intermediate products and capital equipments produced in the richer countries, however, derive benefits from knowledge spillovers. The empirical analysis in this paper shows that what type of intermediate goods and capital eq...

This work deals with a multi-period capacitated location problem inspired by telecommunication access network planning problems, where demands and costs vary from one period to another. On each concentrator site, several capacitated concentrators can be installed at each period. Similarly, several capacitated modules can be installed at each period between each terminal and concentrator sites. ...

This paper briefly described the general production of intelligent agricultural machine in precision agriculture. It summarized the basic principle and the application in precision agricultural demonstration field of those agricultural machines, which mainly included wheat variable ferti-seeder, yield distribution information acquiring system, variable controlled large irrigation system moving ...
