Power electronics based microgrids have advantages in terms of flexibility, reliability, and power density. However, such microgrids are hard to control due to reduced inertia, increased uncertainties, and wide range of operating conditions. In such systems, the strong physical couplings among subsystems (inverter-interfaced distributed generators) must be properly considered. Simply introducing existing...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
In this work, a simple electric circuit model for the evaluation of the impact of vias (inter-metallic vertical connections) in resonant rotary traveling wave oscillator (RTWO) is proposed. A test structure was designed to quantify the degradation on the signal integrity of RTWOs caused by these vias. The test structure and the RTWO were designed according to the rules of the 130 nm commercial mixed...
An approach of a new methodology for skills transfer from machine to human is proposed in this research. This methodology transmits a haptic feed-back using vibrotactile perception to transfer motor skills using a parallel planar robot and virtual reality environments. During the experimentation, the participants tried to learn a specific motion trajectory given by the system. During the process,...
Applications of tiie unbiased finite impulse response (UFIR) estimation approach are discussed to improve measurements of tìie electrocardiography (ECG) signals. One of the standard methods providing denoising and extracting features of the ECG signals is based on the one-step prediction. We show that better accuracy is obtained by using the UFIR filter and the UFIR smoothing filter with adapted averaging...
This work reports the recent advances on the synthesis and characterization of thin Cu2ZnSnS4 (CZTS) films prepared by chemical solution deposition. CZTS colloids dispersed in water-ethanol solutions were used as precursors and prepared by coprecipitation by mixing CuCl2-2H2O, ZnCl2, SnCl2 and thiourea (NH2)2CS in water-ethanol mixtures. The CZTS films were deposited on glass substrates by spin-coating...
A fuzzy codesign approach is proposed to deal with the controller — scheduler design for a networked control system which is physically distributed using a shared communication network. In the proposed approach, a fuzzy controller is applied to generate a control law for different sampling periods, the configuration supposes a strict actuation period vanishing the jitter. A neural uncertainty estimator...
Provides an abstract for each of the presentations and a brief professional biography of each presenter. The complete presentations were not made available for publication as part of the conference proceedings.
In this paper a numerical approach for the position, velocity and acceleration analysis for a 5R parallel manipulator is presented. 5R parallel manipulator is a two degrees of freedom planar mechanism which has been extensively studied by analytical methods. In this work, the use of computational tools such as Matlab and ADAMS is proposed in order to solve the inverse and forward kinematic problem...
In this work is reported a brief summary of considerations for the design of a basic readout CMOS integrated system applied for the conditioning of small signals taken from a floating-gate based CMOS-MEMS capacitive structure intended for inertial measurement. Both the electromechanical structure and the readout circuit (consisting in a variable capacitor coupled to the gate of a MOSFET and a conventional...
This work describes a simple method to produce highly luminescent carbon quantum dots (CQDs) emitting blue or green light. The method consists of the carbonization of citric acid at 250 °C under ambient condition and a further surface functionalization. The UV-Vis spectrum of these carbon nanostructures exhibited a well-resolved absorption band at 320 nm which was attributed to the n-π∗ transition...
In this paper, we present a tracking system to estimate the position of a surgical instrument used in minimally invasive spine surgeries for training. The purpose of our system is to get the information about movements and surgeons skills during the training. The system uses four infrared markers embedded on the surgical instrument of common used. At least two Wii Remote Control is needed for calculating...
