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.

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). (C) 2001 Elsevier Science Ltd. All rights reserved.

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.

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. All rights

Abstract: We have investigated the mechanical properties and elastic constants of zinc-blende
Ga1-xInxN alloys, using the pseudopotential method within the virtual crystal approximation
combined with the Harrison bond-orbital model. 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.

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.
