Adaptation of DSpace to the Specific Needs of the Agricultural Sciences and Technology Community
4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PostersThe aim of this project is to explore the customization of DSpace according to the use of controlled vocabularies. The plug-in shall be easy–to–install modules available free for download on the DSpace site. The objective is the adaptation of DSpace to the specific needs of the Agricultural Sciences and Technology community in order to assure quality in metadata creation. Knowledge Organization Systems such as the AGROVOC thesaurus provide mechanisms for sharing information in a standardized manner by recommending the use of common semantics.Food and Agriculture Organization of the United Nation
Methodology development for evaluation of selective-fidelity rotorcraft simulation
This paper addressed the initial step toward the goal of establishing performance and handling qualities acceptance criteria for realtime rotorcraft simulators through a planned research effort to quantify the system capabilities of 'selective fidelity' simulators. Within this framework the simulator is then classified based on the required task. The simulator is evaluated by separating the various subsystems (visual, motion, etc.) and applying corresponding fidelity constants based on the specific task. This methodology not only provides an assessment technique, but also provides a technique to determine the required levels of subsystem fidelity for a specific task
New Grounded and Floating Simulated Inductance Circuits using Current Differencing Transconductance Amplifiers
Current differencing transconductance amplifier (CDTA) is receiving considerable attention as a building block for current-mode (CM) analog signal processing / signal generation. In this paper, new CDTA based lossless grounded and floating inductance simulation circuits have been proposed. The proposed grounded simulated inductance circuit employs two CDTAs and a single grounded capacitor whereas the floating simulated inductance circuit employs three CDTAs and a grounded capacitor. The circuit for grounded inductance does not require any realization conditions whereas in case of floating inductance only equality of two transconductances is needed (which can be easily maintained in practice by ensuring equal dc bias currents in the two transconductance amplifiers). Some sample results demonstrating the applications of the new simulated inductors using CMOS CDTAs have been given to confirm the workability of the new circuits
