Дослідження роботи базових елементів пам'яті на основі ПЛІС

Базові елементи пам’яті (тригери) входять до складу сучасних цифрових інформаційно-вимірювальних систем (ІВС). Такі ІВС дедалі частіше виконують на основі програмованих логічних інтегральних схем (ПЛІС), основні переваги яких описані в літературі. Програмне середовище Quartus II використовують для розробки цифрових ІВС на основі ПЛІС та їх апаратного тестування. Мета даної роботи – визначення динамічних параметрів тригерів Quartus II та їх порівняння з аналогами

Survey sites and spatially smoothed contour maps of predicted LF mf prevalence in Sierra Leone.

<p><b>A</b>. Predicted mf prevalence at baseline; <b>B</b>. Predicted mf prevalence after three rounds of MDA. The same legend scale was used for the contour map of both A and B for easy comparison. Triangles and labels show the survey locations and the observed mf prevalence in each location.</p

Spatial effects for prevalence of <i>Schistosoma haematobium</i> infection in schoolchildren in Sierra Leone, 2009–2010.

*<p>Variables were standardised to have mean = 0 and standard deviation = 1; CI = Bayesian credible interval; LST = Land Surface Temperature; NDVI = Normalised Difference Vegetation Index; PIWB = perennial inland water body.</p

A scatter plot of the combined proportion with urogenital and intestinal schistosomiasis.

<p>The X-axis shows the observed combined proportion and the Y-axis shows the difference between the predicted and observed proportion infected.</p
