The design thought of "dual-CPU architecture" is used on the basis of a deep study of embedded systems and multi-functional CNC machine tools. That is to say, microprocessor S3C2440A of Samsung ARM9 series is used as control core, whose PWM timer produces pulse to realize the automatic control of the process. As the main control center, it plays the main functions of NC program input, keyboard entry, LCD display, the interpretation of the program, crude interpolation and so on. Using CPU as auxiliary equipment, it receives signals from master control center to realize fine interpolation through further calculation. Simultaneously the periphery of the system expands modules of human-computer interaction, communication, servo, and input/output to realize human-machine interaction, data communication and motor control. Finally, the hardware modules are debugged and the results are analyzed, which shows that the system is of fast response, reliability, low cost and good cutting and portability. This system has achieved the desired anticipation and has broad prospect in the economical CNC field which requires fast moving and proper processing speed.

This paper points out the disadvantages of a formerly proposed data transfer mode used in the monitoring system of WTP. A data transmit solution which uses ZigBee wireless communication standard is proposed, and the technical characteristic of ZigBee technology is introduced. The hardware structure and software design are presented. The paper emphasizes on the realization of ZigBee protocol and data communication flow. The experimental results show that ZigBee is suitable for the wireless data transmission in the WTP. The reliable transmission of data to the control center of WTP has been realized in some in situ applications.

There are three main activities of General Directorate of Land Registry and Cadastre. These are Mapping, Land Registry and Cadastre. Geomatic Department is responsible for mapping activities. The most important projects like TUSAGA-Aktif (CORS-Tr), Metadata Geoportal, Orthophoto Production and orthophoto web services and preparation of Turkish NSDI Feasibility Report have been conducted and completed by this department’s specialists since 2005.<br><br> TUSAGA-Aktif (CORS-Tr) System, serves location information at cm level accuracy in Turkey and TR Nortern Cyprus in few seconds, where adequate numbers of GNSS satellites are observed and communication possibilities are present. No ground control points and benchmarks are necessary. There are 146 permanent GNSS stations within the CORS-Tr System. Station data are transferred online to the main control center located in the Mapping Department of the General Directorate of Land Registry and Cadastre and to the control center located in the General Command of Mapping. Currently CORS-Tr has more than 9000 users. Most of them are private companies working for governmental organization. <br><br> Providing data communication between control center and both GNSS station and users via trusted and good substructure is important. Additionally, protection of the system and data against cyber attacks from domestic and foreign sources is important. This paper focuses on data communication and security issues of GNSS network named TUSAGA-Aktif.

Frequency Identification

The system had achieved a wireless data communication function using AVR SCM as a control center and basing on radio frequency identification technology. The transmitting terminal of system produces a high frequency signal through capacitance connecting three point type oscillator. And the encoded signal will be transmitted after high-frequency carrier modulated. While after the receiving terminal receive the signal through antenna, and the signal after a series processes including amplification, detection, rectification, voltage comparison will be processed by SCM. The system includes temperature humidity sensor, clock generator chip, photosensitive element, could detect the surrounding environment signal and wireless transmit. The paper elaborates the soft and the hardware realizing specific course of the wireless transmission system. It has an important meaning for the wireless transmission technique.

The Impact

More than two billion people suffer from anemia worldwide, and it is estimated that more than 50 % of cases are caused by iron deficiency. In this community intervention trial, we evaluated infants aged 10 to 23 months of age (n = 171) from two public child day-care centers. Intervention lasted 18 weeks. The 50-g individual portion (uncooked) of fortified rice provided 56.4 mg of elemental iron as ferric pyrophosphate. Capillary blood samples to test for anemia were taken at baseline and at endpoint. The objective of this study was to evaluate the impact of rice fortified with iron (Ultrarice®) on hemoglobin and anemia prevalence compared with standard household rice. For the fortified rice center, baseline mean hemoglobin was 113.7 ± 9.2 g/L, and at endpoint 119.5 ± 7.7 g/L, p < 0.0001; for the standard rice center, baseline mean hemoglobin value was 113.5 ± 40.7 g/L, and at endpoint 113.6 ± 21.0, p = 0.99. Anemia prevalence for the fortified rice center was 27.8 % (20/72) at baseline, and 11.1 % (8/72) at endpoint, p = 0.012; for the control center, 47.1 % (33/70) were anemic at baseline, and 37.1 % (26/70) at the end of the study, p = 0.23. The Number Needed to Treat (NNT) was 4. In this intervention, rice fortified with iron given weekly was effective in increasing hemoglobin levels and reducing anemia in infants.

Roasting Time

Roasting coffee manually is widely applied by coffee producers. This process takes a very long time and is less efficient in terms of productivity for industry standards. This machine  is equipped with a thermocouple sensor as a temperature sensor that will measure the temperature in the roasting cylinder, then equipped with a timer as a reminder of roasting time that ranges from 15 minutes at a temperature of 200 degrees Celsius, this machine  is also equipped with android as a timer controller on the coffee roaster machine. This machine is also equipped with a microcontroller and Bluetooth as a media transmitter and data receiver. From the test results obtained data that Bluetooth can be used for data communication between the microcontroller and Android with a distance of 30 meters in the room, and 12 meters outside the room. If it exceeds that distance, then Bluetooth will not respond back
