Application of Radio Environment Map Reconstruction Techniques to Platoon-based Cellular V2X Communications
2020
Vehicle platoons involve groups of vehicles travelling together at a constant inter-vehicle distance, with different common benefits such as increasing road efficiency and fuel saving. Vehicle platooning requires highly reliable wireless communications to keep the group structure and carry out coordinated maneuvers in a safe manner. Focusing on infrastructure-assisted cellular vehicle to anything (V2X) communications, the amount of control information to be exchanged between each platoon vehicle and the base station is a critical factor affecting the communication latency. This paper exploits the particular structure and characteristics of platooning to decrease the control information exch…
Experimental system for the study of the directional thermal emission of natural surfaces
2004
A new automatic experimental system was designed to improve the accuracy of multidirectional thermal infrared measurements. This experimental system mainly consists of two identical thermal cameras operating at 8-13 mu m, one metal ring to keep the constant view area for different view angles and a goniometer, which is composed of: (1) a semicircular roadway of 2 m diameter to change the observation angle in the azimuth direction; (2) an elevator of 1 m height to adjust the measuring level to the target level; (3) a rotating arm equipped with one thermal camera for changing the observation angle in the zenith direction; and (4) a fixed arm equipped with another thermal camera to record at n…

Divu valodu salīdzinošā analīze bilingvāli runājošiem: franču un nūfu valodā
2022
Šis darbs sniedz atbildi uz problēmjautājumiem, kas rodas bilingvālajās kopienās visā pasaulē, lai parādītu valodu prakses ietekmi uz runātāja ikdienas dzīvi. Daudzvalodu valstīs, piemēram, Kamerūnā, kur valodu skaits sasniedz 250, bilingvāli runājošie, šajā gadījumā franču-nu'fī valodā runājošie, izjūt savas valodas lietošanas pozitīvu vai negatīvu ietekmi. Minētajā kontekstā bilingvālo prasmju lietošana nepaliek bez ietekmes uz runātāju. Viņi var izjust pozitīvu vai negatīvu kognitīvo ietekmi atkarībā no apgūtajām prasmēm. Ja kompetences līmenis ir ļoti zems, kognitīvai ietekmei ir apvērsuma efekts, ja kompetences līmenis abās valodās ir pietiekošs vai līdzvērtīgs, runātājs izjūt pozitīvu…
Design and validation of a wireless Body Sensor Network for integrated EEG and HD-sEMG acquisitions
2022
Sensorimotor integration is the process through which the human brain plans the motor program execution according to external sources. Within this context, corticomuscular and corticokinematic coherence analyses are common methods to investigate the mechanism underlying the central control of muscle activation. This requires the synchronous acquisition of several physiological signals, including EEG and sEMG. Nevertheless, physical constraints of the current, mostly wired, technologies limit their application in dynamic and naturalistic contexts. In fact, although many efforts were made in the development of biomedical instrumentation for EEG and High Density-surface EMG (HD-sEMG) signal ac…
Scientific HIV research in Africa and the Middle East: a socio-economic demographic analysis
2021
Background: In Africa, HIV/AIDS research is concentrated in certain countries, particularly South Africa. This distribution may not accurately reflect the disease prevalence or the true research efforts of countries.Objectives: To identify HIV/AIDS research productivity of countries in Africa and the Middle East, in absolute terms and adjusted for people living with HIV, population size and economic development.Methods: We identified all the articles and reviews on HIV and AIDS in the Web of Science Core Collection in which African or Middle Eastern countries had participated. After determining the number of documents produced by each country, we adjusted the findings for the number of peop…
