In this paper, the output regulation problem of linear multi-agent systems through one leader is considered. The overall system consists of a leader agent, which can access the exogenous signal, and the followers agents. The method considers a static feedback control law of the output agents and a robust control applied to the leader agent, allowing synchronization of the agents in the system. Finally, a numerical example illustrates the efficacy of the presented results.

In this paper a quasi-floating-gate charge/discharge method is presented and a novel application for the widely used membrane-like RF-MEMS switches is proposed as well. The design of a four-beam capacitive MEMS structure is described within the 0.5 microns (2P3M) CMOS technology framework. Furthermore, the device is electromechanically simulated in the COMSOL Multiphysics suite and electrically simulated via a custom SPICE model. Finally, the possible use as an electromechanical switch to provide an initial desired electric potential to the floating gate in a flotating-gate MOS transistor (FGMOS) device is discussed.

Nanoparticles of Titanium dioxide (TiO2) in anatase phase have been synthesized through a homogeneous precipitation method using titanium butoxide (Ti(OBu)4 as precursor of Ti. The synthesis was performed by mixing (Ti(OBu)4 in ethanol at 55°C. Then, glacial acetic acid and sulfuric acid were slowly added under constant magnetic stirring until obtaining a white precipitate. Afterwards, this precipitate was centrifuged, dried, calcined, and milled in a planetary ball milling. All powders were characterized by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). To study the gas sensing properties, pellets were manufactured from synthesized TiO2 powders, these properties were evaluated by measurement of surface resistance change of pellets, at different temperatures and propane concentrations. Additionally, to increase the gas sensing response of pellets to propane gas, the TiO2 powders were mixed with different proportions of alumina (Al2O3) powders, this mixture was carried out in order to increase the porosity of pellets, hence increasing the surface area.

In this document we present an intelligence device which includes a monitor system for automatic movements of a robotic hospital bed based on posture classification and identification. This functionality has been developed in response to the requirements defined by the application of a diagnostic methodology [10]. Our diagnostic methodology applied on a Mexican public hospital allowed us to understand that the problem of mobility in elderly people and disabled people involves solutions like devices that attend these individuals to achieve movement without many complications. The movement of these patients can be performed routinely or sporadically during their stay in hospital. For patients who require certain routine application of this movement is designed an intelligent monitor system. This intelligent system allows medical experts to program the movements of the robotic bed considering the patient's posture and time. We will show a methodology for bodies classification in real time. Our work considers the problem of human posture classification with few information (sensors), applying digital process to expand the original data of the sensors and so get more significant data for the classification, however, this is done with low-cost algorithms to ensure the real-time execution.

Mesoporous structures of zinc oxide (ZnO) powders were prepared by the homogenous precipitation method. ZnO nanoparticles were synthesized from a solution of zinc acetate dihydrate (Zn(CH3COO)2.2H2O) as zinc source and ammonium carbonate ((NH4)2CO3) as precipitant agent. Structural and morphological characteristics were studied with respect to changes in molarity (0.05, 0.5, and 0.35 M), percentage of saturation, synthesis temperature (30, and 70°C), and time (30, 60, and 120 min). ZnO phases were confirmed from X-ray Diffraction (XRD) results. The particles morphology (size and shape) was analyzed from the Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) characterization.

The Ziegler paradox establishes that: given a stable non-conservative mechanical system with at least two degrees of freedom, if we add a small damping the resulting system may be unstable. In this paper we extend this paradox for systems with one degree of freedom. The result is based on changing periodically the coefficients of the system. Some numerical results are presented for the Mathieu's and Meissner's equations.

This paper presents a method for three-dimensional reconstruction using only the images captured from an Unmanned Aerial Vehicle (UAV). First, the camera pose is computed using a known marker on the scene as reference, then, a three dimensional point cloud reconstruction is performed using Multi-View Stereo software (MVS); and finally the polygon mesh is generated using the Advancing Front technique. The results show that the obtained polygon mesh is a good approximation of the surface, precise enough for applying standard algorithms for path planning and obstacle avoidance.

In this work the authors report on the application of a continuous sliding mode controller (CSMC) and a classical Proportional - Integral (PI) controller to a distillation column. The controllers are applied to maintain constant the outlet product concentration, or a tray temperature, in the distillation column. As it is well known, the main characteristic of controllers based on the sliding mode control theory is their robustness to uncertainties. This characteristic makes the application of sliding mode controllers very useful to distillation columns, a chemical process with nonlinear dynamics and disturbance presence. Performance of controllers is based on output tracking reference and electric power consumption.

In this work we present a study of morphological characteristics evolution in the various layers comprising a Si:H p-i-n structure, which are deposited by PECVD on “Corning” glass substrates coated with transparent conductive Al-doped zinc oxide (AZO). AFM measurements were conducted over area of 2 × 2 μm2 to determine morphological characteristics of the substrates, carbon layer, p-layer, as well as intrinsic layer and finally the n-layer. AFM study of surface morphology showed that average height, kurtosis and rms roughness changed with the same tendency as the subsequent layers were deposited, while skewness showed opposite behavior. The maximum value of roughness is 3.14 nm for AZO layer and the lowest roughness value of 2.23 nm was achieved in the n-type layer.
