This paper presents a novel method for defining,analyzing, testing and implementing the basic combinationalcircuitry with VHDL Simulator. This paper shows the potentialof VHDL modeling and simulation that can be applied toTernary switching circuits to verify its functionality and timingspecifications. A novel method is brought out for implementingthe basic combinational ...

The current tendency of ight control system designs is towards increased integration of applications and increased distribution of computational elements. The reliability analysis of such systems is di cult because subsystem interactions are increasingly interdependent. Researchers at NASA Langley Research Center have been working for several years to extend the capability of Markov modelling t...

By introducing autonomous or software-controlled systems, human operators are increasingly required to perform cognitive-intensive tasks in addition existing labour-intensive tasks. As a result, it will be more difficult identify roles future complex systems with traditional approaches such as hierarchical task analysis used the conventional HRA. This paper proposes novel systematic approach fo...

The FSQ-series FPSTM (Fairchild Power Switch) is an integrated Pulse Width Modulation (PWM) controller and Sense FET specifically designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS) with minimal external components. Figure 1 shows the internal block diagram of the FSQ-series. Compared with discrete MOSFET and PWM controller solution, it can reduce total cost, component count,...

Digital stochastic measurement method implementation is considered from signal stationarity point of view. It is shown how conceptual block diagram for digital stochastic measurement of one Fourier coefficient can be simplified and used for developing conceptual block diagram for measuring predefined set of signal harmonics. Hardware of digital stochastic measurement block interfaced to recordi...

Today, the popularity of social networks poses a great threat to user’s information, thus the work of security and privacy protection is becoming increasingly important and urgent. This paper aims to explore the problem of user identification based on biometrics methods in security and privacy issues for social networks sites. In this paper, we propose a lightweight fingerprint recognition mech...

Communication and interoperation are critical to modern industry. A reconfigurable intelligent gateway based on ARM and FPGA is proposed on the basis of current situation and developing trend of protocol converting to achieve communication and interoperation among heterogeneous field bus systems and TCP/IP network. The functional block diagram, hardware architecture, software structure and prot...

Medical educators have a unique role in teaching students how to save lives and give comfort during illness. This article reports a qualitative inquiry into medical students’ perspectives on the key qualities which differentiate excellent and poor clinical teachers, using a Web-based questionnaire with a purposeful sample of thirdand fourth-year medical students. Thirty-seven medical students r...

With the rapid advances of computer-based technology in mission-critical domains such as aerospace, military, and power industries, critical systems exhibit more complex, dependent, and dynamic behaviors. Such dynamic system behaviors cannot be fully captured by existing reliability modelling tools. In this paper, we introduce a new reliability modelling tool, called dynamic reliability block d...
