Simulation-Based Study to Quantify Data-Communication Benefits in Congested Airport Terminal Area.

Are long-haul truck drivers unusually alert? A comparison with long-haul airline pilots.
2020
Abstract Background Recent studies suggest heavy vehicle drivers self-estimate their sleepiness unexpectedly low during night duties. The present study compared sleepiness ratings of long-haul truck drivers with those of long-haul airline pilots during night and non-night duties. In addition, the correspondence between self-rated manifest and predicted latent sleepiness was examined in the two groups. Methods Twenty-two drivers and 33 pilots participated. Their working hours, sleep, on-duty sleepiness, and use of sleepiness countermeasures were measured in naturalistic conditions. Predictions of latent sleepiness were based on the measurements of working hours and sleep using the Sleep/Wake…

Factors Differentiating Rural and Urban Population in Determining Anxiety and Depression in Patients with Chronic Cardiovascular Disease: A Pilot Stu…
2021
The aim of this cross-sectional study was to analyze selected variables differentiating rural from urban populations, as well as identify potentially increased levels of depression and anxiety in patients with chronic cardiovascular disease. The study was carried out in 193 patients. The study used the Camberwell Assessment of Need Short Appraisal Schedule (CANSAS), the Health Behavior Inventory Questionnaire (HBI), the WHOQOL-BREF Quality of Life Questionnaire, and the Hospital Anxiety and Depression Scale–Modified Version (HADS-M). Spearman’s rank correlation coefficient test and logistic regression were used for analyses. In rural patients, we observed a relationship between anxiety and …
LATVIJAS BEZPILOTA GAISA KUĢA TIRGUS VIDES IETEKMĒJOŠO FAKTORU ANALĪZE
2016
Maģistra darbs „Latvijas BGK tirgus vides ietekmējošo faktoru analīze”. Maģistra darba hipotēze – bezpilota gaisa kuģa nozare strauji attīstās, tas var izraisīt lūzuma punktus valsts sektorā, attiecīgi likumdošana nespētu sekot jaunākajām tendencēm. Šī nespēja sekot radītu gan ekonomiskos zaudējumus, gan bloķētu potenciālās biznesa iespējas uz vispārējo sabiedrības informētību šajā sfērā. Maģistra darba mērķis – izpētīt bezpilota gaisa kuģa galvenos nozares problemātiskos punktus un dot priekšlikumus veiksmīgai, sakārtotai un attīstības pilnai nākotnei. Maģistra darba ietvaros veikts bezpilota gaisa kuģa teorētiskais apskats un pētījums par bezpilota gaisa kuģa tirgus vides ietekmējošajiem …
Nursing students' perceptions of a video-based serious game's educational value: A pilot study.
2018
Abstract Background Despite an increasing number of serious games (SGs) in nursing education, few evaluation studies specifically address their educational value in terms of face, content, and construct validity. Objectives To assess nursing students' perceptions of a video-based SG in terms of face, content, and construct validity. In addition, the study assessed perceptions of usability, individual factors, and preferences regarding future use. Design A pilot study was conducted. Setting and Participants An SG prototype was implemented as part of two simulation courses in nursing education: one for home health care and one for hospital medical-surgical wards. The SG aimed to teach clinica…
Bezpilota gaisa kuģu attēlu apstrādes iespējas medūzu Aurelia aurita kvantificēšanā Rīgas līcī
2022
Globāli ir novērota medūzu biomasas palielināšanās, kas saistīta ar klimata pārmaiņām, eitrofikāciju un pārzveju. Medūzu populāciju pieaugums negatīvi ietekmē un liecina par nelabvēlīgu jūras ekoloģisko stāvokli, kā arī traucē akvakultūras, tūrisma, būvniecības, enerģētikas un citu industriju funkcionēšanai. Tomēr Baltijas jūras reģionā vienota medūzu kvantificēšanas metodoloģija joprojām nepastāv. Šī bakalaura darba mērķis ir izvērtēt bezpilota gaisa kuģu attēlu apstrādes iespējas ausainās aurēlijas Aurelia aurita kvantificēšanā Rīgas līcī. Darbā veikta zinātniskās literatūras analīze, veikti medūzu novērojumi ar bezpilota gaisa kuģi gar Rīgas līča dienvidaustrumu piekrasti, analizēti uzņe…
Wastewater-based epidemiology for early warning of SARS-COV-2 circulation: A pilot study conducted in Sicily, Italy
2022
There is increasing evidence of the use of wastewater-based epidemiology to integrate conventional monitoring assessing disease symptoms and signs of viruses in a specific territory. We present the results of SARS-CoV-2 environmental surveillance activity in wastewater samples collected between September 2020 and July 2021 in 9 wastewater treatment plants (WTPs) located in central and western Sicily, serving over 570,000 residents. The presence of SARS-CoV-2, determined in 206 wastewater samples using RT-qPCR assays, was correlated with the notified and geo-referenced cases on the areas served by the WTPs in the same study period. Overall, 51% of wastewater samples were positive. Samples we…
Calibration and simulation of ASM2d at different temperatures in a phosphorous removal pilot plant
2006
In this work, an organic and nutrient removal pilot plant was used to study the temperature influence on phosphorus accumulating organisms. Three experiments were carried out at 13, 20 and 24.5 degrees C, achieving a high phosphorus removal percentage in all cases. The ASM2d model was calibrated at 13 and 20 degrees C and the Arrhenius equation constant was obtained for phosphorus removal processes showing that the temperature influences on the biological phosphorus removal subprocesses in a different degree. The 24.5 degrees C experiment was simulated using the model parameters obtained by means of the Arrhenius equation. The simulation results for the three experiments showed good corresp…
