Coriolis vibrating gyroscopes can be modeled by a planar resonator, using masses, springs and damping. In this paper, the corresponding equations are studied in order to characterize real vibrating cells. It is shown how to present the problem to allow efficient numerical simulations and analytic developments. In particular, the use of the method of Averaging is fundamental, simplifying most of the...
Critical to the successful implementation of Open System Architecture (OSA) test software, in accordance with the requirements of IEEE 1641[1][2], is the implementation Signal Libraries using the Test Signal Frameworks (TSFs) that provide the test program set (TPS) Developer with the suite of defined signals to be used for the test software. This paper aims to provide insight for the TPS developers...
This paper deals with the analysis of a pyrolysis unit cooler. The pyrolysis unit is built during solution of a EU grant project focused to the use of non-traditional energy sources, especially to produce hydrocarbon mixture from different type of waste. Pyrolysis gas from the pyrolysis reactor enters to cooling system, consisted of two cooling units. This paper deals with the analysis of the first...
The paper describes the application of the intelligent products concept in a road freight transport by instrumenting this activity in certain ways to create an ongoing informational continuum that connects products, vehicles and the persons making the transportation decisions. This instrumentation is developed and implemented under the aegis of the PRODIGE project, whose purpose is to design technical...
Modelling and simulation of the organization structure, communications and functionality of the brains of living creatures has been of interest to philosophers, scientists, engineers and artists for centuries. The possibilities for large numbers of simple microprocessors to be programmed to operate in a way which mimics the human brain, raises the knotty problem of how to do parallel programming....
Fuel cell stacks containing hundreds of individual cells are capable of generating high voltage and current values needed for transportation, commercial, residential, portable and industrial power applications. Although majority of hydrogen produced today comes from reformulated natural gas generated through a process that creates a significant amount of carbon dioxide, fuel cell is still a viable...
Simulation tools for learning power electronics are grounded aimed to study the circuit structure and execution and to evaluate the working possibilities in different duty modes of operation. The power converter estimation factors, features and characteristics are evaluated. Detailed explanation of the models of AC/DC, DC/AC, AC/AC AND DC/DC power converters and their control circuits is given. The...
