An algorithm for damage detection in a multi-story building modeled by a wave equation with Kelvin damping is presented. Damage detection is achieved by relating stiffness loss with reduction in the shear wave velocity of the seismic induced motion propagation through the structure. In order to estimate wave velocity and damping parameters, an identification system based on the least squares method with forgetting factor is used. In addition, a parameterization is presented based on linear integral filters, which eliminates constant disturbances, attenuate measurement noise and depend only on acceleration signals. Once parameters information is available, a detection threshold is designed that compares them with reference values. The experimental results validate the feasibility of the proposed method.

This work studies two delay-based nonlinear controllers and their tuning methods aimed to servodrive control. The first controller is the Cascade Nonlinear Proportional Integral Retarded (CNPIR) control law, which is composed of two nested loops. The inner loop is regulated through an Integral Retarded (IR) Controller and the outer loop uses a nonlinear proportional (NP) controller. The second controller, which is called the Modified Nonlinear Proportional Integral Retarded (MNPIR) controller is a structural modification of the original Proportional Integral Retarded PIR controller, and also has an inner-outer loop structure. The topology of both controllers is presented as well as their tuning methodologies. Numerical results allow assessing the performance of these controllers when applied to a servodrive model.

In this work the fractal dimension was calculated (FD) using the Higuchi´s algorithm in time domain, with the objective of identified the echoes contained in ultrasonic signals, in order to differentiate echoes from oscillations due to electric noise.Once the echo reference (signal) was set, the wavelets scales were chosen (Morlet, Mexican Hat y Daubechies 5); from all these, the Wavelet Morlet has the best performance, therefore this was used to estimate time delays in the ultrasonic signals acquired in water.

As the application domains of sampling-based motion planning grow, more complicated planning problems arise that challenge the functionality of these planners. One of the main challenges is the weak performance when reacting to uncertainty in robot motion, obstacles, and sensing. In this paper, a multi-query sampling-based planner is presented based on the optimal probabilistic roadmaps algorithm that employs a hybrid sample classification and self-adjustment strategy to handle diverse types of planning uncertainty. The proposed method starts by storing the collision-free generated samples in a matrix-grid structure. Using the resulted grid structure makes it computationally cheap to search and find samples in a specific region. As soon as the robot senses an obstacle during the execution of the initial plan, the occupied grid cells are detected, relevant samples are selected, and in-collision vertices are removed within the vision range of the robot. Furthermore, a second layer of nodes connected to the current direct neighbors are checked against collision which gives the planner more time to react to uncertainty before getting too close to an obstacle. The simulation results in problems with uncertainty show significant improvement comparing to similar algorithms in terms of failure rate, processing time and minimum distance from obstacles. The planner was also successfully implemented on a TurtleBot in two different scenarios with uncertainty.

Model-based optimization tools for demand side management using supermarket refrigeration systems are considered. A model for medium-sized supermarket freezer and cooler temperatures is developed, as well as for the CO2 compressor cycle power consumption. Model parameters are estimated from measured data. The formulation of an optimization problem vs. various electricity markets is briefly discussed, and an illustrative numerical simulation of demand side management optimization in a supermarket is provided. The developed model provides a feasible tool for including the supermarket thermal capacity dynamics into the optimization problem.

A current treatment method of cutaneous and subcutaneous tumors is based on an application of electroporation, known as Electrochemotherapy (ECT). We infer, from the outcomes reported on these malignancies, that ECT might be utilized for eradication of primary deep-seated breast malignancies. The aim of this work is therefore, to establish an electroporation protocol specific for breast tissue, based on a finite element model of electroporation of BT-20 cells, and in vitro electroporation. These electroporation protocols were compared with those obtained with a second cell line SKOV-3, an ovarian carcinoma derived cell line, in order to determine whether the cellular origin has an effect on efficiency of an electroporation protocol predicted by computational models simulating in vitro conditions. Efficiency was verified through the determination of propidium iodide uptake and cell viability by epifluorescence microscopy and MTT assay. The results show that a protocol of 8 pulses of 150 V, pulse width of 100 μs, and pulse repetition frequency of 1 s, leading to a cell viability of 98.7 % in SK-OV-3 cell line is in accordance with the computational model predictions. Nonetheless, this protocol must be modified to a protocol of 8 pulses of 140 V, pulse width of 100 μs, and pulse repetition frequency of 1 s, so that a maximal cell viability of 89.1 % in BT-20 cell line can be obtained. A limitation of the methodology in this work is the atypical use of suspended SK-OV-3 and BT-20 cell, since they are adherent i.e., these cells require a substratum to keep their epithelial and morphological features which may lead to significant variations whether electroporation of attached cells was carried out. Nevertheless, the contribution of this research is the determination of a first specific protocol of reversible electroporation for a human breast cancer cell line. Consequently, the establishment of organ-specific electroporation protocols planned prior to experimental application is encouraged.

This paper deals with the problem of outdoors implementation of consensus strategies for velocity tracking of a Multi-Agent System (MAS). To overcome the inherent issues present in these type of applications, we developed testbed to based on a reliable communication network that enables a team of multiple Unmanned Aircraft Systems (UAS) to achieve velocity matching. In order to prove the effectiveness of the proposed platform we perform two different experiments at outdoors environments with a team of three UAS. Finally, we provide the conclusions and discuss the main results of our work, as well as the future directions of this project.

Based on output-feedback, we solve the regulation control problem for a planar vertical take-off and landing device (PVTOL). We use the well-known energy shaped approach together with the I&I method, to derive the corresponding controller. We apply the theorem of LaSalle in the convergence analysis. We validate the obtained control method through numerical experiments.
