Year: 2001 Title: A two-layer robot controller design using evolutionary algorithms Journal: Journal of Intelligent & Robotic Systems Volume: 30 Issue: 1 Pages: 73-94 Date: Jan Short Title: A two-layer robot controller design using evolutionary algorithms ISSN: 0921-0296 DOI: 10.1023/a:1008122728715 Accession Number: WOS:000166545900004 Abstract: The results obtained by a rule-based proportional, integral, derivative (PID) precompensator controller applied to a two-joint manipulator are discussed. The end effector is made to follow a specified trajectory obtained from the inverse kinematics by an appropriate design of a fuzzy control law. The desired trajectory is determined by the values of the joint variables and the structural kinematics parameters of the manipulator. The performance of the PID controller is exploited here to build a fuzzy precompensator that will enhance the conventional PID and to obtain better performances and results. The fuzzy rule base of the precompensator designed is found by associating two evolutionary algorithms that search for the optimal solution.

Year: 2001 Title: Stabilizing effect of epoxidized sunflower oil on the thermal degradation of poly(vinyl chloride) Journal: Polymer Degradation and Stability Volume: 74 Issue: 3 Pages: 501-505 Short Title: Stabilizing effect of epoxidized sunflower oil on the thermal degradation of poly(vinyl chloride) ISSN: 0141-3910 DOI: 10.1016/s0141-3910(01)00170-7 Accession Number: WOS:000172361500017 Abstract: Unsaturated triglyceride oil (sunflower) was obtained from commercial sources. It was epoxidized and characterized by chemical and spectroscopic methods. The thermo-oxidative degradation of poly(vinyl chloride) at 180 degreesC was investigated. The effects of different metal carboxylate combinations (Ba/Cd and Ca/Zn stearates) in the presence of epoxidized sunflower oil on static heat treatment of PVC have been studied. In order to compare the efficiency of the epoxidized sunflower oil with these metal soap stabilizers, thermal stabilities were evaluated on the basis of evolved hydrogen chloride determined by potentiometric titration and the degree of discoloration are discussed. The development of color and the dehydrochlorination rates were compared for PVC sheets containing epoxidized sunflower oil (ESO) or epoxidized soya bean oil (ESBO). It was found that ESO exerted a stabilizing effect on the degradation of PVC. Further-more, the thermal degradation of PVC with metal soaps and ESO was investigated by thermogravimetric analysis (TG) and differential thermogravimetric analysis (DTG).

Year: 2001 Title: Antimony dopant redistribution during copper silicide formation Journal: International Journal of Inorganic Materials Volume: 3 Issue: 8 Pages: 1299-1301 Date: Dec Short Title: Antimony dopant redistribution during copper silicide formation ISSN: 1466-6049 DOI: 10.1016/s1466-6049(01)00141-6 Accession Number: WOS:000172877700047 Abstract: In the present work, copper silicide formation and the redistribution of implanted Sb+ ions were studied by means of Rutherford backscattering spectrometry (RBS) and X-ray diffraction (XRD). Copper thin films, of 500 A thickness, were evaporated, at room temperature, onto Sb implanted Si(111) wafers. Two doses, 5 x 10(14) and 5 x 10(15) Sb+ cm(-2), were used at 130 keV. The samples were heat treated in vacuum by conventional thermal annealing in the temperatures range 500-700 degreesC for various times. It was observed that, independent of Sb implant dose, two silicides (Cu3Si and Cu4Si) were formed in the considered temperature range. Antimony ions implanted initially in the Si substrates were found to redistribute towards the sample free surface. (C) 2001 Elsevier Science Ltd. All rights reserved.

Year: 2001 Title: Effect of implanted phosphorus on silicide formation in the Cr/Si(111) system Journal: Thin Solid Films Volume: 385 Issue: 1-2 Pages: 61-65 Date: Apr Short Title: Effect of implanted phosphorus on silicide formation in the Cr/Si(111) system ISSN: 0040-6090 DOI: 10.1016/s0040-6090(00)01864-2 Accession Number: WOS:000167666600010 Abstract: Chromium layers 800 Angstrom thick are deposited by electron gun evaporation on: respectively, non-implanted, 5 x 10(14) and 5 x 10(15) at./cm(2) P+-implanted Si(111) substrates. The redistribution of phosphorus and the influence on chromium silicide growth are analyzed by secondary ion mass spectroscopy (SIMS) and Rutherford backscattering spectroscopy (RBS) after annealing between 450 degrees and 550 degreesC. It is shown that chromium silicide formation is retarded or inhibited by the presence of phosphorus. The implant diffuses out of the CrSi2 surface layer in both implantation cases, but also accumulates at the CrSi2/Si interface in the case of the higher dose. (C) 2001 Elsevier Science B.V.

The agreement between our results and the available experimental and other theoretical data was generally satisfactory. Special attention has been given to the effect of alloy disorder on the studied quantities. For this purpose, the compositional disorder is added to the virtual crystal approximation as an effective potential. It is found that except for the anisotropy factor, the compositional disorder should not be ignored in the calculations of the remaining studied quantities of alloys of interest.

Year: 2001 Title: Investigation of cerium oxide pellets for optical glass polishing Journal: Glass Technology Volume: 42 Issue: 2 Pages: 60-62 Date: Apr Short Title: Investigation of cerium oxide pellets for optical glass polishing ISSN: 0017-1050 Accession Number: WOS:000170791500004 Abstract: Optical glass polishing using cerium oxide abrasive bonding with resin permitted its to achieve high quality surfaces in a short time. The glass surface roughness is influenced by, the surface state of the cerium oxide pellet. We found that the pellet's surface and the glass surface are abraded during the polishing process and that there is a proportionality between the removal rates of the optical glass and of the cerium oxide pellets characterised by the relative volumetric wear.
