The Domain Name System Security Extensions (DNSSEC) architecture is based on public-key cryptography. A secure DNS zone has one or more keys and signs its resource records with these keys in order to provide two security services: data integrity and authentication. These services allow to protect DNS transactions and permit the detection of attempted attacks on DNS. The DNSSEC validation proces...

The semi-trailer chassis was usually treated as rigid body in many existing literature, which would lead to larger deviation from actual situation. A rigid semi-trailer chassis model was built and flexiblized based on the modal test results in this paper. The tractor semi-trailer with flexible chassis was utilized to simulate the rollover scenarios on high speed obstacle avoidance under emergen...

A significant fraction of fatalities involving passengers in automobile accidents is due to severe Head Injury. Head impact safety which in turn is the occupant safety is a significant consideration particularly in the design of Passenger Vehicles. During the rollover of SUV the head comes in contact with the parts such as the B-Pillar so in order to evaluate the occupant safety during rollover...

An anti-rollover control algorithm based on the Time-To-Rollover (TTR) index is proposed in this paper. A simple model with steering and differential braking inputs was developed to calculate the TTR in real-time. The TruckSim dynamic simulation software is used to verify the final control performance, as well as simulating the dynamics in the driving simulator. Both the simple and complex (Tru...

Heavy vehicles make up a relatively small percentage of traffic volume on Malaysian roads compared to other vehicle types. However, heavy have been reported be involved in 30,000–40,000 accidents yearly and caused significantly more fatalities. Rollover may also incur cargo damages cause environmental or human disasters for that carry hazardous cargos if these contents are spilled. Thus, this p...
