Kompetencje warunkujące funkcjonowanie na współczesnym rynku pracy
2017
W artykule poruszono problematykę związaną z kształceniem kompetencji zawodowych w świetle aktualnych wymagań rynku pracy, a także zarys najistotniejszych kompetencji twardych i miękkich poszukiwanych wśród osób chcących podjąć pracę zawodową. Uwzględniono również oczekiwania pracodawców w stosunku do absolwentów szkół, w szczególności szkół zawodowych. Przedstawiono też najważniejsze postulaty,mające na celu zwrócenie uwagi na konieczność ciągłego nabywania nowych i doskonalenia już posiadanych kompetencji zawodowych.
A Velocity Estimation Technique for a Monocular Camera Using mmWave FMCW Radars
2021
Perception in terms of object detection, classification, and dynamic estimation (position and velocity) are fundamental functionalities that autonomous agents (unmanned ground vehicles, unmanned aerial vehicles, or robots) have to navigate safely and autonomously. To date, various sensors have been used individually or in combination to achieve this goal. In this paper, we present a novel method for leveraging millimeter wave radar’s (mmW radar’s) ability to accurately measure position and velocity in order to improve and optimize velocity estimation using a monocular camera (using optical flow) and machine learning techniques. The proposed method eliminates ambiguity in optical flow veloci…
Localization of Multi-Class On-Road and Aerial Targets Using mmWave FMCW Radar
2021
mmWave radars play a vital role in autonomous systems, such as unmanned aerial vehicles (UAVs), unmanned surface vehicles (USVs), ground station control and monitoring systems. The challenging task when using mmWave radars is to estimate the accurate angle of arrival (AoA) of the targets, due to the limited number of receivers. In this paper, we present a novel AoA estimation technique, using mmWave FMCW radars operating in the frequency range 77–81 GHz by utilizing the mechanical rotation. Rotating the radar also increases the field of view in both azimuth and elevation. The proposed method estimates the AoA of the targets, using only a single transmitter and receiver. The measurements are…
Classification of Targets Using Statistical Features from Range FFT of mmWave FMCW Radars
2021
Radars with mmWave frequency modulated continuous wave (FMCW) technology accurately estimate the range and velocity of targets in their field of view (FoV). The targeted angle of arrival (AoA) estimation can be improved by increasing receiving antennas or by using multiple-input multiple-output (MIMO). However, obtaining target features such as target type remains challenging. In this paper, we present a novel target classification method based on machine learning and features extracted from a range fast Fourier transform (FFT) profile by using mmWave FMCW radars operating in the frequency range of 77–81 GHz. The measurements are carried out in a variety of realistic situations, including p…
Non-Linear Inductor Models Comparison for Switched-Mode Power Supplies Applications
2022
The use of non-linear power inductors, intended as devices exploited up to a current at which the inductance is halved, is of great interest in switched-mode power supplies (SMPSs). Indeed, it allows the use of lighter and cheaper inductors improving the power density. On the other hand, the analysis of SMPSs equipped with non-linear inductors requires appropriate modeling of the inductor reproducing the inductance versus current. This paper compares two main analytical models proposed in the literature: the former is based on a polynomial, and the latter exploits the arctangent function to reproduce the non-linearity of the inductance. Performance is compared by considering the effort of r…

Planthology: an Application System for Plant Diseases Management
2017
The goals of modern agriculture are obtaining high yields that meet the increasing nutritional requirements of the World population. This is extremely difficult for three kind of reasons: i) the lands dedicated to agricultural use are strongly reduced in industrialized Countries; ii) farmers prefer an homogeneous product, because it is easier to manage, with consequent reduction of biodiversity, iii) globalization and climate change have led to the introduction of new pathogens and pest in environments other than original ones, resulting in serious production losses. The consequences of these problems, followed by not timely intervention leads to conditions that make not possible to obtain …
Does English fall on deaf ears? A study of the motivational state of deaf and hard-of-hearing pupils of English
2009
Motivaation katsotaan yleisesti olevan yksi tärkeimmistä vieraan kielen opiskeluun vaikuttavista tekijöistä, ja se onkin sen takia paljon tutkittu ilmiö. Vähemmistöryhmät ovat kuitenkin näissä tutkimuksissa jääneet lähes huomiotta. Esimerkiksi kuurojen ja huonokuuloisten motivaatiota opiskella vieraita kieliä ei juuri ole tutkittu. Hyvänä esimerkkinä on kuitenkin ollut Hanni (2007), joka teki kvalitatiivisen tutkimuksen haastattelemalla seitsemää kuuroa heidän englannin kielen opiskelukokemuksistaan peruskoulusta korkeakouluopintoihin. Koska kaikki kuurot, kuten kaikki kuulevatkaan, eivät mene peruskoulun jälkeen lukioon, saati korkeakouluihin, tarkempi peruskouluvuosien opiskelumotivaation…
Mise en œuvre d’une architecture de gestion de collision pour le déploiement efficace d’un NoC sur multi-FPGA
2015
International audience; Le déploiement d’un NoC (Network On Chip) sur plusieurs FPGA nécessite que des routeurs partagent un même lien de communication entre FPGAs, créant des goulots d’étranglement [1]. Dans ce papier, nous proposons une structure de gestion de collision intégrée entre le NoC et le point d’accès du protocole FPGA. Cette structure est basée sur les algorithmes utilisés dans les réseaux informatiques et adaptée aux NoC [2].
