Expert systems for decision support have recently been successfully introduced in road transport management. These systems include knowledge on traac problem detection and alleviation. The paper describes experiments in automated acquisition of knowledge on traac problem detection. The task is to detect road sections where a problem has occured (critical sections) from sensor data. It is necess...

The COVID-19 case was first identified in Makassar City, Indonesia on March 2020, then continued to experience an increase positive cases and designated as a red zone/epicenter of the spread COVID-19. On April 24, city government for time took steps limit activities outside home community reduce risk spreading virus. 29, Gowa Regency is bordered north also implemented mobility restrictions from...

Various studies indicate that at the same noise level and during the daytime, annoyance increases in the order of rail, road, and aircraft noise. The present study investigates if the same ranking can be found for annoyance to nocturnal exposure and next day cognitive performance. Annoyance ratings and performance change during combined noise exposure were also tested. In the laboratory 72 part...

An efficient statistical algorithm of automatic extracting road from SAR images is devised in this paper. First, an feature detecting operator is used to find the road candidate. Then another smaller operator which calculating the homogenous statistic of locate region is applied to reduce the false alarm and smooth the road edge. Finally, the road linear features are extracted by fusing the res...
