Allocation of actuators and sensors for coupled-adjacent-building vibration attenuation
2013
An actuator and sensor allocation approach is proposed for the design of coupled-adjacent-building vibration suppression under seismic excitation. This paper first establishes a full-order model of adjacent buildings with the location information of actuators and sensors. Then, the order of the model is reduced via modal cost analysis, by retaining the modes contributing the most. In view of the fact that the output powers of the actuators are limited, this paper brings forward a mixed H∞/GH2 control. By considering that not all the states of the system can be measured by the sensors, a dynamic output feedback controller is designed. The genetic algorithm is employed to obtain the locations…
Optimizing the MAC Protocol in Localization Systems Based on IEEE 802.15.4 Networks
2017
Radio frequency signals are commonly used in the development of indoor localization systems. The infrastructure of these systems includes some beacons placed at known positions that exchange radio packets with users to be located. When the system is implemented using wireless sensor networks, the wireless transceivers integrated in the network motes are usually based on the IEEE 802.15.4 standard. But, the CSMA-CA, which is the basis for the medium access protocols in this category of communication systems, is not suitable when several users want to exchange bursts of radio packets with the same beacon to acquire the radio signal strength indicator (RSSI) values needed in the location proce…

A Novel Method of Distance Measurement Based on Pulse Position Modulation and Synchronization of Chaotic Signals Using Ultrasonic Radar Systems
2009
This paper deals with a novel method of transmission and receipt of a signal based on both the property of two chaotic systems generating the same chaotic signal when they are synchronized and the property of pulse position modulation (PPM) to be insensitive to the distortions of the transmission channel. The method is discussed in the context of ultrasonic radar systems, in which the transmitter and receiver, which consist of ultrasonic sensors, are near each other, and the received signal consists of the transmitted signal reflected by an obstacle. A reference sinusoidal signal is superimposed to a chaotic signal generated by a master chaotic system, and the whole signal is modulated acco…
A photovoltaic system suitable for the battery pack charging of an electrically power assisted velocipede
2012
The paper describes the designing, sizing, realization and setting up of a complete system suitable for the management of an electrically power assisted velocipede using a photovoltaic module for the charging of the batteries. In the work an overview on the sustainable mobility needs and on the commercial electrically power assisted velocipedes is presented and the "Ecolapa" prototype, set up in the SDELab laboratory of Palermo University, is precisely described underlining the designing, implementation and setting up phases of the photovoltaic charging system settled up on the velocipede. Moreover tests oriented on the setting up of the whole system and validation tests on the prototype ar…
Autonomous patrol and surveillance system using unmanned aerial vehicles
2015
Unmanned aerial vehicles (UAVs) are increasingly popular for civil applications due to their flight capabilities and mobility. This paper proposes an indoor autonomous patrol and surveillance system using unmanned aerial vehicles. The system consists of six components: (1) a low cost vision-based pose estimation of UAVs, (2) vision-based state estimation, (3) UAV patrol path planning, (4) UAV controller to desired waypoints, (5) manual joystick controller and (6) assignment of priority hierarchy to multiple control inputs of a robot. The components were integrated successfully and the designed system was experimented in an indoor setup. Results has shown that the proposed system is suitable…
The Advantages of the Network-based Electronic Teaching Package by the Implementation of English for Specific Purposes Course
2015
Abstract The article analyses the advantages of English for Specific Purposes teaching of the fourth year students majoring in “Electrical and Power Engineering” at National Research Tomsk Polytechnic University by means of the network-based electronic teaching package. This paper analyzes the structural content of the network-based electronic teaching package, shows the key approaches used to develop this tool and focuses on the description of its main components. The conclusions made are based on the results obtained over a three year period (2012-2015) of the network-based electronic teaching package use.
Medical English in Italian University Courses in Sports Sciences: Some Issues in Focus
2014
Over the last few decades, the increasingly rapid progress of medical science and technology, together with the growing importance of English as the language of international communication, has made the study of medical English a crucial segment in the curriculum of medical undergraduates. In Italy, medical topics are studied not only in medical degree courses but also in those of sports sciences. This paper focuses attention on some medical English-related issues in sports sciences degree courses in Italian universities. More precisely, the work is divided into four main parts. The first part raises the terminological question concerning the denomination of the discipline “lingua inglese”/…
Heavy Gas Dispersion Modelling Over a Topographically Complex Mesoscale
2005
Potentially dangerous events involving heavy gas dispersion and their severe consequences have been largely publicized by the media. Simplified models have been widely applied to describe the effects of these accidents. However, most simplified models deal with flat terrain scenarios and are based on quite crude simplifications of the complex phenomenology involved. In this paper the possibility of simulating the dispersion of heavy gas clouds over a large topographically complex area (tens of km) by a general purpose computational fluid dynamics (CFD) code is investigated. The aim is that of setting up a tool able to produce a realistic description of such dispersion processes, whose resul…
El management de las conductas socioemocionales. Una aproximación teórica y empírica desde el caso de los agentes de "contact centers"
2020
How is a specific type of emotion-related work conducts formed today? What principles guide these conducts and what effects do they have on those who work? The study of Contact Center agents allows us to understand how a set of personal qualities such as patience and good treatment of others, certain desires and personal impulses or even intimate sensations such as anguish or individual expectations have become managerialized emotions that end up modifying the inner attitudes of these agents. Within this framework, we propose a theoretical approach that integrates the work of Weber, Foucault and Elias, which invites us to reflect on a socio-emotional manner of leading one?s life (Lebensfu?h…
