Quality of service has become crucial in wireless communications, due to the high data rates needed to provide multimedia services with sufficient quality. In this sense, the integration of OFDM in wireless technologies has made it possible to grant reliable communications, reducing the effects of attenuation and multipath propagation that degrades the services in environments where the devices are located. This problem may become even more important if, as it is expected, the classical broadcast TV is left to the wireless network operators, in order to recover the frequencies that are currently used for this service. This paper aims to provide efficient tools to estimate the coverage of an OFDM transmission system using stochastic geometry and information theory to model the capacity of a cell when users are known to the transmitter (multicast situation). We consider that users are distributed uniformly over a fixed radius ball from the base stations. We derive the equations and develop simulations to model the distribution of channel capacity to ensure a certain quality of service. Our results indicate that for a user, on average, wireless multicast can be improved by 20% compared to classical broadcast.

Citizen criminality is a social problem that affects to some big cities un the world. Specifically, in Lima, Peru, there is a serious problem on criminality. However, this problem is very different in each district of Lima city. In addition, people, who comet crime, reside generally in other district. In this way, in this work, a geospatial analysis of the place where reside the people who committed crime, is developed, by applying of the grey clustering method. The case study was carried out in thirty-two districts of Lima city, in order to analyze the provenance of prisoners in the jails of Lima city. The results showed that the districts with more prisoners in the jails of Lima city were San Juan de Lurigancho, Cercado de Lima, and Villa el Salvador. In addition, the districts with less prisoners in the jails of Lima city were Ancon, Carabayllo, and Puente Piedra. The results of this study could help to local and central government to make the best decision on the criminality in the districts of Lima city by applying of focused plans or programs.
公民犯罪是影响世界上一些大城市的社会问题。具体来说，在秘鲁的利马，犯罪问题非常严重。然而，这个问题在利马市的每个区都有很大的不同。此外，犯罪的人一般住在其他地区。这样，在这项工作中，通过应用灰色聚类方法，开发了犯罪人居住地的地理空间分析。案例研究在利马市的32个区进行，目的是分析利马市监狱中囚犯的来源。结果显示，利马市监狱中囚犯人数较多的地区是San Juan de Lurigancho、Cercado de Lima和Villa el Salvador。此外，利马市监狱中囚犯较少的地区是安孔、卡拉巴约和普恩特皮德拉。本研究的结果可以帮助地方和中央政府通过实施重点计划或方案，对利马市各区的犯罪行为做出最佳决策。

Power System State Estimation (PSSE) is a substantial matter in the management of electrical power systems (EPS). This article provides a referential study for the understanding of the Sequential Importance Sampling (SIS) Particle Filter (PF) with a Systematic Resampling (SysR) in PSSE. Two performance indexes are used to assess the performance of the SIS PF with SysR: an index of error ($epsilon $) and the J Performance Index. Also, the implementation of the method was tested in two standard power systems, the IEEE 14-bus and 30-bus test cases, under two scenarios which are the normal operation and sudden load change. The algorithms that support the implementation of the method were tested in MATLAB. From test results, they help support the feasibility of the method for state estimation applications.

This paper deals with the design of a Multi-level inverter to produce higher number of voltage levels using series connected basic units with reduced switch count. A new basic unit is proposed and by connecting a number of the proposed basic unit in series, only positive multilevel voltage can be obtained. To generate negative voltage levels, single phase H-bridge is included to the circuit. By using the proposed topology with trinary progression, a 53-level of output is produced. Using MATLAB/SIMULINK the proposed Multi-level inverter topology is simulated and analyzed in terms of total harmonic distortion.

In this paper, a solar-pumping system based on a single-stage photovoltaic generation topology is presented. A standard two-level three-phase inverter is connected between an array of solar panels and a centrifugal pump. The inverter is operated to extract the maximum power available from the PV system and the pump is driven by a cage induction machine. A predictive control strategy is used to regulate the AC machine currents. Simulations considering changes in the solar irradiance are presented showing the feasibility of the proposed control scheme.

The use of wireless sensor networks for collecting geolocated sightings of marine fauna can provide useful information for wildlife conservation agencies and scientific studies. Both, networking services and data quality can benefit from the integration of social paradigms in the design of these networks. This paper explores the implementation of a wireless sensor network where social interaction among network nodes occurs, which is also known as the Social Internet of Things (SIoT). Here, smartphones are used as sensors for monitoring wildlife with the support of the users, integrating a communitary approach between the nodes. The data is managed by using a web platform, which enables the community to visualize and share information. Results correspond to hundreds of good quality sightings collected after the first few months of operation.

The development of an algorithm for the control of traffic flows that avoids situations of congestion is a hot topic in the computer networks. This paper presents a mathematical model for a general computer network and then discrete control theory is used as a key tool to design the traffic flow control algorithm that avoids congestion in a high-speed computer network, the proposed algorithm also ensures the stability of the computer network. The results of the simulations show that the proposed algorithm is able to adjust the sending speed and queue level in the buffer rapidly. In addition, the method is easy to implement to a high-speed computer network.

In this paper, a control is implemented in a squirrel cage motor using the model referencing adaptive system. To perform this control, an adaptation algorithm is necessary, so we proceed to use and compare a PID family controller and a Fuzzy controller. The comparison will be made graphically contrasting the speed of the models in their transitory states and applying load in their stationary states.

This paper focuses on the robust control of a single stage boost inverter using a model that accounts for both small and big signal properties of the inverter. The aim is to determine a state feedback controller for the small signal model such that it is able to reject perturbations existing on the three-phase currents while keeping the system stable and with a response quick enough. Based on the well-known theory of robust control, a feedback controller is proposed in order to minimize the $H_{infty }$ norm of the system while taking in account the variable load and a D-Stability region that will guarantee the speed required for the perturbation effect to decay. The proposed controller is simulated and the results are analyzed and discussed.

In this document, the second part of the development of a continuous positive bi-pressure system as a respiratory support for patients with respiratory disorders while they sleep, such as sleep apnea-hypopnea, will be discussed. The focus is on the control strategy used and it corresponds to a gain-scheduling PID control by means of empirical modeling. The objective was to design a low cost equipment that could adjust to the requirements of a device for the treatment of Obstructive Apnea Syndrome. Although the final prototype has not been finished, it is considered that the imposed objective has been achieved.
