Polystyrene is one type of plastic that is hard to be degraded, because of that, it requires an alternative to reduce polystyrene waste through biofoam. Biofoam which is made of starch is reinforced with bacterial cellulose that has high hydrophilic properties. This study aims to know the effect of ZnO addition to crystallinity and water absorption capacity of biofoam based cassava starch reinforced bacterial cellulose. The method used experimental design. Synthesis of biofoam was conducted using baking process method with varied the ZnO content in the biofoam were 0%, 3%, 6%, 9%. The resulted samples were analyzed by X-ray diffraction and water absorption test to determine the effect of ZnO concentration. The results showed that the addition of ZnO variation into biofoam caused the change in diffraction position and intensity. The control variation (0% ZnO) had the highest diffraction peak at the position of 20.88°2θ with an intensity of 68.65 counts, crystallite size of 20.795 nm. After adding ZnO variation of 3%, 6%, 9%, diffraction position and intensity change to be 36.31°2θ and 276.29 counts, 36.26°2θ and 558.81 counts, and 36.31°2θ and 725.78 counts, respectively. The addition of ZnO into biofoam composite decreased water absorption up to 33% compared than the control sample, and the lowest optimum absorption resulted in ZnO concentration of 9% with water absorption value of 0.164 (gH2O/g).

The conventional structures of active magnetic bearings to support rotors dispose of eight poles operating in such a way that two adjacent poles share the same magnetic flux. In this work, a different electromagnetic structure is presented which is based on the so named bearingless motor with split windings. While this device is originally supplied by alternate electrical currents, in this case, as the purpose is to generate only radial forces, the windings are supplied by continuous currents forming a magnetic flux with four equivalent poles. To test this approach, a conventional induction motor was used and its rotor was appropriately modified. It will be shown that although the magnetic fluxes are coupled, for low speed rotation, all the controlled plant can be modeled as an unstable second order system, so PID controllers can be appropriately designed. In order to test this approach, a workbench consisting of displacement sensors, signal conditioners and two microcontrollers development boards was implemented. For different radial loads and changes of displacement references, the experimental results were well succeeded.

On the side of enhancing the execution of skills, specialists in sports are adopting analysis of kinematics to correct actions of an athlete. By means of technological resources used to measure physical variables and to supply relevant data to trainers, results related to improvements on athletes' performance are being achieved. In this context, this work uses the Radial Basis Function Neural Networks (RBF-NNs) combined in cascade with a Genetic Algorithm (GA) as a cross-correlation method, likewise Multiobjective Differential Evolution (MODE) and self-adaptive MODE (using JADE - Adaptive Differential Evolution with Optional External Archive - self-adaptation method) for optimization. The RBF-NNs have been applied to predict the swimmers velocity profile being multiple correlation coefficient (R~2) adopted to evaluate the optimization techniques during both estimation and validation stages. A data acquisition system was used to capture the para-swimming athletes' instantaneous velocity data, swimming 25 meters in crawl, breaststroke, backstroke, and butterfly strokes. Looking at the results achieved, self-adaptive MODE outperforms classical MODE in approach point of view considering all cases studied, finding the best RBF-NN framework to identify the profile of speed in swimming.

Nano-crystalline Ti and TiN thin-films fabricated on <100> P-type Si wafers via magnetron sputtering are characterized by transmission Kikuchi Diffraction (TKD) in an FEI Sirion scanning electron microscope (SEM). A simple and cost-effective sample preparation combined with the TKD experiment at working distance of ~ 3 mm and a tilt of 35° produced indexable Kikuchi patterns. Pole figures generated by automatic and manual indexing revealed <0001>|| normal direction (ND) fiber texture and <111>||ND fiber texture in monolithic Ti and TiN thin-films, respectively. Glancing angle x-ray diffraction results corroborated the texture in the samples. Spatial resolution of ~ 60 nm is achieved that is close to the limit of resolution in conventional electron backscatter diffraction (EBSD). It is demonstrated that a simple sample preparation method in TKD technique combined with selected area electron diffraction (SAED) in transmission electron microscope (TEM) may reveal fundamental knowledge about different mechanisms occurring during fabrication and processing of the thin-film systems.
