Hydrological Considerations in Designing Roadways: Avoiding Hydroplaning
(2022)High water levels on lanes poses high risk to the safety on highways. Since drainage structures are mostly focused on water spread issue at sideways, consequences of the buildup flow on the surface is overlooked . This ... -
Hydrological Considerations in Designing Roadways: Avoiding Hydroplaning
(2022)Safety on highways is essential, but high water levels on lanes risk that. Drainage structures are mostly concerned with water spread at sideways and ignore the build-up flow on the surface. This study addresses whether ... -
IESR: Instant Energy Scheduling Recommendations for Cost Saving in Smart Homes
(IEEE, 10.05.2022)The exponential increase in energy demands continuously causes high price energy tariffs for domestic and commercial consumers. To overcome this problem, researchers strive to discover effective ways to reduce peak-hour ... -
