That structure and properties of the rock mass highly uncertain.This paper describes the influence of geological engineering and geotechnical conditions on the primary lining of a main road tunnel. The deformation of the primary lining was analyzed in terms of the percentage share of sandstones and ...
On-road measurement is an effective method to investigate real-world emissions generated from vehicles and estimate the difference between engine certification cycles and real-world operating conditions. This study presents the results of on-road measurements collected from urban buses which propelled by ...
The scooter's robust suspension system, including front oil suspension and rear spring suspension, provides a smooth and comfortable ride over various terrains, including off-road and road conditions. The scooter's LED lights, including front and rear turn signals, headlights with Bluetooth ...
The formation of black ice on the road surface combined with reduced visibility may lead to fatal pile-up crashes, especially, in harsh snowy weather conditions. A recent pile-up crash involving over 100 vehicles on Interstate-80, Wyoming, caused the death of three people and the closure of ...
We should race to formulate an action plan for carbon peak by 2030 and support localities with proper conditions to achieve carbon peak first. February 19, 2021, the 18th Meeting of the Central Committee for Deepening Overall Reform Establish a sound economic system for green and low-carbon ...
wider and longer beam pattern that makes it easier to see further ahead on the trails, aiding in driver safety at night and low light conditions. The amber backlight feature of the S8 adds a stylish touch to an enthusiast’s vehicle and can be used as a marker for added visibility when...
Particularly, in Tunisia the road transport represents 80% of the total national transportation sector. It consumes around 70% of the total energy demand in transport sector. Consequently, the management of road transport sector is on particular priority in Tunisia. This is due to the rapid ...
2. We have done a lot of treatment for waterproofing, but we can't promise you the scooter damaged by water is still under guarantee, because 100% waterproofing is impossible under the current technical conditions. In addition, riding on rainy days is very unsafe. We strongly recommend that ...
For the shift scenarios, two tests (Shift—2 h ON, 2 h OFF and Shift—3 h ON, 2 h OFF) and one control (No Shift—0 h) conditions were considered. In the shift scenarios, the ON/OFF conditions represent occupational presence where the 𝑝𝑖pi value in Equation (3) is one and...
…, which are typical conditions for the off-road applications and it has a different impact on the roll dynamics with respect to a global road geometry such us the presence of a bank angle. Indeed, the roll dynamics derived from the asymmetrical excitation induces a persistent condition of ...
