This work describes the implementation of a jammer prototype implemented on a drone that is activated by an operator agent. In the implementation process, a prototype reconfigurable Antenna Microstrip Type E was developed that guarantees signal propagation in 2.4 and 5.8 GHz. The jammer control stages in the drone were also designed, consisting of data acquisition cards, sensors detection photoelectric and wireless communication cards, allowing the operator to decide the exact moment to carry out the attack. In addition, a remote control has been implemented that allows the operator to know the physical position of the target with respect to the position of the attacking drone. Finally, the operational tests were carried out in two stages, in the laboratory, analyzing the spectrum generated by the jammer, and in the field, which includes jamming tests on a commercial drone. Thanks to the results obtained, the operation of the prototype that inhibits the video transmission of the attacked target was verified.

In structural bioinformatics, computational biology, or any other field where is important to assess cavities, clefts, pores, or grooves in a macromolecular system, it is imperative to perform this evaluation over a trajectory or an ensemble of structures to measure all possible structural changes produced by the atomic movements, especially in the constriction regions. This is mainly true in membrane proteins such as ions channels or transporters where the movements of the amino acid residue side chains that form the pore can significantly alter their dimensions and thus affect the protein function. In this work, we present a brief tutorial to measure the radius of the pore within macromolecules in large structural ensembles using non-commercial software widely reported in the literature.

Various unmanned aerial vehicles (UAVs) have recently emerged and deployed in several real-life applications. The complexity of the coupled and underactuated dynamics and the presence of uncertainties and disturbances have shaped several research projects. Indeed, numerous intelligent and robust linear and nonlinear flight controllers have been investigated in the literature. In this paper, the evolution over the years of UAVs is presented and, a classification is proposed based on different parameters, as well as the advantages and disadvantages of each type. Finally, several applied control algorithms to the UAVs are investigated where a brief explanation is given. The contribution of this work is to give an orientation to the flight control researcher on UAV's nonlinear control.

In this paper, two techniques are used to experimentally improve the solar cells efficiency by coating the outer surface of the panels with oil and chlorophyll. Coating the outer glass of solar cell with small layer of oil improves the value of sunlight absorbed by panel and accordingly the efficiency of the panels dramatically increases due to high transmissivity of some types of oils, especially vacuum oils. In this experiment, four types of oils are examined such as vacuum oil, engine oil, abro oil used as a mineral oils and sunflower oil examined as a natural oil. During the experiment, it has been observed the efficiency of the solar cell panels that have been coated with vacuum oil (labovac oil) increased by 11.28% compared to the efficiency of the same panel before coating. Similarly, coating the outer surface of solar panel with 1.5 mm layer of chlorophyll improves the efficiency by 4.17% as chlorophyll absorb a wide range of sunlight falling on surface of the photovoltaic panel and thus increase its efficiency.

The little opportunity in the care of patients awaiting surgery causes multiple and serious consequences for them, their family and relatives. Given the complexity of the hospital system, and specifically operating room systems, their current planning has ample space for productivity improvement. This work uses simulation modeling approach to build a valid model of the OR system in the public hospital of Puerto Montt- Chile. To describe the model, activity data from the ORs and waiting lists for the year 2017 is used (near 15,000 interventions, an initial waiting list of 6,500 patients, 15 ORs, 150 surgeons, four daily hourly periods and consideration of weekends] to model the operation of the system using statistical and probability techniques. The model is validated using more than a dozen of performance indicators making it adequate to represent the true dynamics of the system in a simulation study.

With the evolution of communication technologies, new applications have emerged aiming to improve the processes of information exchange and innovation, at the forefront of this evolution is the fifth generation of mobile networks (5G), which should provide the infrastructure for these new applications that have high capacity, reliability, energy efficiency and latency requirements. In this context, there are a number of changes that must be made to the network infrastructure, including Core Network (CN) and Radio AccessNetwork (RAN) to support these new applications. In this work we demonstrate the implementation of Quality of Service (QoS) control through the Software Defined Network (SDN) paradigm in an abstract (CN) infrastructure, with the objective of investigating the benefits of using SDN for new scenarios and challenges for 5G network. Experiments carried out with the Ryu SDN controller, demonstrated that the application of QoS through the SDN can bring benefits to the performance of these new applications.

Due to the large presence of solar power plant in electric power networks, it became obligatory to study the interaction between them and the associated networks. In this paper, a Distribution Static Synchronous Compensator (D-STATCOM) is used to improve the performance of a photovoltaic generation plant (PV) during three phase fault of interconnected grid. Artificial neural networks (ANN) based on Lightning attachment procedure optimization (LAPO) is used to tune the control parameters of D-STATCOM in targeted with PV plant. The LAPO is used for generating historical data needed for ANN. In order to point out the contribution of this paper, the performance of PV system without and with D-SATCOM is compared during three-phase fault and when D-STATCOM is tuned by LAPO only and by proposed ANN.

Combined-cycle power plants recycle steam or gas to generate additional power and reduce emissions. In this research work, the boiler of a combined-cycle power plant is controlled using three control strategies, which are designed and compared, for the variables drum water level ($L$) and superheated steam pressure ($p_{s}$). A conventional PI controller is designed using the Lambda-tuning technique to obtain the optimal controller's gains. In addition, a fuzzy logic-based controller that considers the error and the error's rate-of-change is applied. Finally, a model predictive control (MPC) is applied, which objective function is to minimize the steady state error and the variation of the control actions, thus the fuel consumption is reduced. The controllers' performance is compared by analyzing maximum overshoot, settling time, steady-state error, and mainly fossil fuel consumption, which influences the operating cost. The results show a proper performance of the three control techniques. However, MPC control achieves a higher reduction of fuel consumption.

Dust accumulation effects for the solar panels are adverse factors, which affect the efficiency, output power and current. The humidity increased the dust particles adhesion force on a surface which increased the hardness of removing dust. In this research after coating the PV modules, it has the hydrophobicity on the surface to make self-cleaning and allow more visible light to be transmitted to improve the efficiency of solar panels, which made difference of transmittance for the experimental group and the uncoated module about 7% and archives significant increase for short-circuit current (Isc) about 6%. The maximum output power (Pmax) for experiment E3 is higher than the uncoated PV module by 46.5% and the efficiency also is higher than the uncoated PV module by 48% after self-cleaning of dust. Infrared light is the main effect on the operating temperature for solar panels. In our study the chemical structure of Nano antimony tin oxide (Nano ATO) heat-insulated super hydrophobic films has the characteristics of reflecting infrared light and transmitting visible light to decrease the temperature of PV modules. The gradual changing for mole ratio of Nano ATO in the three experimental group can show gradual difference of transmittance on the three PV modules such as E3, E2 and E1 have transmittance about 83%, 83.6% and 84.9%. And achieved difference temperature of E3 about 7.4 °C with enhancement about 17%, Isc about 6% and Pmax average without dust effects about 14.4% and compared with uncoated film.

Predictive torque control (PTC) has been established as one of the viable solutions for variable-speed motor drive control, particularly where a fast response for torque and flux control is required. The main reason for its adoption is the exible architecture and good performance attained with a predictive control scheme. One of the main issues with this approach is the variable switching frequency. Therefore this paper presents an implementation of PTC to overcome this issue. The method consists on the application of two active plus zero voltage vectors to generate a fixed number of switching commutations in the inverter legs during each sampling period. The dwell time for each of the voltage vectors are calculated in the optimization process of the predictive control. The scheme is validated simulation results, demonstrating the constant switching frequency operation whilst keeping the high dynamic torque and ux response.
