The Digital Bridge is a new generation of DC resistance test instrument for cables and wires. It can automaticallyselect the electric current according to dierent cables and wires, and displays the test results rapidly. This paperdesigns a kind of digital electric bridge instrument with self-calibration based on ARM9 core processor. This instru-ment can complete high-speed data acquisition, data recording and processing functions, and possesses custom RS232based communication protocol for data communication with the host computer. In order to eliminate the error ofADC chip and improve the measurement accuracy, the instrument uses a self-calibration method on both hardwareand software.
Our main aim in the present work is to study the influence of heat transfer analysis of thin film flows of a third grade fluid in the presence of magneto hydrodynamic (MHD) on a vertical moving belt. The momentum and energy equations are solved analytically by using the Adomian decomposition method (ADM). The results include the velocity profile, average velocity, volume flux and the temperature distribution across the film. Particular attention is given to the combined effect of heat transfer and MHD on the velocity field. Optimal Homotopy Asymptotic Method (OHAM) is also used for comparison. The numerical results and absolute errors are derived in tables. The influence of different parameters on velocity profile and temperature distribution is discussed graphically
We witness more and more often a diversification of the elements of underground economy, as potentiated by the effects of the global economic crisis. If in the previous years we have witnessed manifestations related to tax evasion, gambling or bribery, nowadays the aspects of the underground economy are represented by organizing criminal activities after the model of legal businesses (reception, production, transport, recovery, protection sectors) and white-collar crime. Sometimes these activities of organized crime surpass the capacity of the state to limit them as the specialists in the tax and legal areas prefer to offer their services to private employers who afford to pay them more than the state. Last but not least the globalization has created conditions in which money, weapons or human trafficking runs optimally between international groups of organized crime through the easy access to international networks of data or transport. Moreover, organized crime groups became focused on the control of financial institutions or banks, under the cover of which they could transfer huge amounts of money. In this respect, it appears that besides its positive features, globalization has created an environment in which organized crime groups have easily extended beyond state borders becoming real transnational crime industries.
