Coverage study of a sustainable IoT system for industrial applications

2022

Los dispositivos del Internet de las Cosas (IoT) son muy útiles para monitorizar información en escenarios industriales incluso en zonas que tienen difícil acceso a través de las conexiones tradicionales. Las comunicaciones inalámbricas fiables pueden ser un reto en entornos industriales, donde la señal de comunicaciones es a menudo bloqueada debido a la presencia de maquinaria industrial, con posibles bloqueos intermitentes y/o impredecibles. Este artículo evalúa las características de cobertura de un despliegue sostenible y de bajo coste de dispositivos IoT para monitorizar una instalación industrial dedicada al diseño y montaje de sistemas de automatización para la industria alimentaria.…

Precision Agriculture: Past, Present and Future

2011

From 1978 the Global Positioning System, needed for sensing the position of military targets (e.g. buildings, machinery), was developed as a pure military system, while in 1983 it was made available also for public use. Therefore, at the beginning of 80s precision agriculture, requiring GPS for sensing the position to which any measured field parameter must be geo-referenced, was implemented for the first time in US. In fact, soil and crop parameters are spatially variable in a field, so that spatially uniform rate crop input applications cause increased environmental impact and crop input waste. In order to reduce the environmental impact and optimise the use of crop inputs, precision agri…

An IPMSM torque/weight and torque/moment of inertia ratio optimization

2014

In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…

Čukstošas galerijas modas rezonatoru temperatūras sensors

2019

Čukstošo galerijas modu (ČGM) rezonatori ir sfēriskas formas objekti, kas ir taisīti no optiski caurspīdīgiem materiāliem un ir spējīgi uzturēt optiski cirkulējošu vilni iekšā sfērā, izmantojot pilnīgu iekšējo atstarošanos. Ja ir monohromātisks gaismas avots ar konstantu intensitāti, tad vilnis, kas kustās pa lodes perimetru, sāk konstruktīvi interferēt. Šajā gadījumā rodas rezonanse, ko sauc par čukstošo galeriju modu (ČGM), pēc analoģijas no akustikas. Darbā tiek aplūkots koncepts, ka ČGM rezonatorus varētu izmantot kā temperatūras sensorus. Izmantojot dažāda lieluma rezonatorus un mainot tempratūru, tiek testēta sistēma un rezonanses. Darbā tiek veidota praktiska sistēma ar kuras palīdzī…

Cilvēka kustību novērošana, izmantojot inerciālos sensorus

2020

Cilvēka kustību novērošana, izmantojot inerciālos sensorus, mūsdienas ir ļoti populāra pētniecības metode, ko pielieto medicīnā, rehabilitācijā, sportā un citās nozarēs. Darbā tika izpētītas tehnoloģiskās iespējas, lai veiktu cilvēka kustību novērošanu, kā arī esošie pielietojumi cilvēka kustību novērošanai hokejā. Darba mērķis ir veikt profesionāla un entuziasta līmeņa hokejistu hokeja metienu kustību novērošanu, lai noteiktu, kura entuziasta hokeja metiens procentuāli visvairāk atbilst profesionāla hokeja metiena sasniegtajam lineārajām paātrinājumam. Novēroto datu apstrādei, tika izmantota “Python” programmēšanas valoda, ar kuru tika …
