Internal redundancy - the way to improve robot dynamics and control performances
(Dordrecht : Kluwer Academic Publishers, 2000)
The research follows the concept of variable geometry. The concept was originally introduced for general mechanical system in order to improve its dynamic behaviour. Here, we apply the concept to robots. It can be shown ...
Aerosol synthesis of phosphor based on Eu3+ activated gadolinium oxide matrices
Poster presented at the Seventh International Conference on Ceramic Processing Science, Inuyama, Japan, May 15-18, 2000
Modeling boron separation from water by activated carbon, impregnated and unimpregnated
(Roma : Società chimica italiana, 2000)
The sorption of boron from boric acid water solution by impregnated activated carbon has been studied Barium, calcium, mannitol, tartaric acid and citric acid were used as chemical active materials. All processes were ...
Line-profile analysis of nanostructured ZnO powders obtained by freeze-drying method
(Uetikon-Zuerich : Trans Tech Publ, 2000)
Freeze-drying, as a cryochemical powders processing method is applied in ZnO submicrometar to nanosized powders synthesis. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum by ...
Hydroxyapatite/poly-L-lactide (Collagen) biocomposite with poly-L-lactide of different molecular weights
(Weinheim : Wiley-VCH Verlag, 2000)
In this communication we describe the preparation of HAp/PLLA biocomposites by hot pressing of HAp powder with PLLA of different molecular weights, with and without the addition of collagen. We made PLLA of low molecular ...
Rapid formation of high Tc phase in Bi-Pb-Sr-Ca-Cu-O system
The preparation of high purity 140nm sized Bi-Pb-Sr-Ca-Cu-O particles is based on thermal decomposition of aerosol generated ultrasonically (at 1.7Mhz) from IM nitrate precursor which contain organic additive. Particle ...
The equivalent electrical model of intergranular impedance of BaTiO/3-ceramics
(2000 22nd International Conference on Microelectronics, MIEL 2000 - Proceedings, 2000)
In this paper, the equivalent intergranular impedance model of BaTiO/sub 3/-ceramics is generated taking into consideration two types of connections between grains. The models are applied to a cluster of up to three spherical ...
Oxidation of metallic binder powder and its influence on mechanical properties metal-diamond composite
(Sendai : Japan Institute of Metals, 2000)
In this paper, the properties of metallic binders based on Co, Fe, bronze and their influence on mechanical characteristics of metallic binder-diamond composites, obtained by hot pressing of these powders, were analyzed. ...
The Schottky barrier contribution to photoacoustic effect in Au-Si system
The photoacoustic effect in metal-semiconductor system, i.e., the influence of Schottky barrier on the thermal and electronic transport processes in semiconductor was investigated. The amplitude and phase spectra were ...
The influence of urea on the formation process of BiPbSrCaCuO superconducting ceramics synthesized by spray pyrolysis method
The influence of urea on the formation process in the Bi-Pb-Sr-Ca-Cu-O system, as well as, on the final high Tc. phase content and morphology of the powders obtained by spray pyrolysis method was studied. The process ...
