At present the disposal of waste tyres is becoming a major waste management problem in the world. It is estimated that 1.2 billions of waste tyre rubber produced globally per year. It is estimated that 11% of post consumer tyres are exported and 27% are sent to landfill, stockpiled or dumped illegally and only 4% is used for civil engineering projects. Hence efforts have been taken to identify ...

Future vehicular sensors will further increase active and passive safety systems of cars and trucks. One particular promising objective is to gather tyre data as temperature, vibration, acceleration and tyre pressure by mounting sensors in the tyres. Since they are the actual elements which transfer the occurring acceleration and — more important — deceleration forces, any additional informatio...

This paper describes a repeatability test, comparing conventional X-ray diffraction (XRD) analyses with the technique of quantitative X-ray diffraction (QXRD) as a determinant of mineral abundance. The conjunctive use of both methods allows specific mineral abundances to be matched between scene of crime (SOC) and suspects where soil or substrate mineralogy is similar. In our test, samples from...

Due to limited energy resources, high energy demand and constrict emission norms led the researchers to find alternative fuel for IC engines. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Many alternative fuels have been developed and commercialized like alcohols, biodiesel, LPG, CNG etc. pyro...

The tractive performance justification of an off-road vehicle is so important that it ensures the vehicle mobility over the unprepared peat terrain. Tractive performance of Low Ground Pressure (LGP-30) wheeled vehicle is investigated on the low bearing capacity moderate peat terrain in Malaysia. The simulation results showed that the vehicle sinkage is more than the critical sinkage value of 10...

Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. Th...

In this paper, we consider the problem of estimating unknown parameters of the so-called Pacejka’s model of a tyre from measurements of the car behavior. Differently from other estimation problems, the tyre parameters may change during the car life due to tyre aging, the variability of the inflation pressure, or many further reasons. Rather then solving a single estimation problem, thus, the is...

Wear and tear from tyres significantly contributes to the flow of (micro-)plastics into the environment. This paper compiles the fragmented knowledge on tyre wear and tear characteristics, amounts of particles emitted, pathways in the environment, and the possible effects on humans. The estimated per capita emission ranges from 0.23 to 4.7 kg/year, with a global average of 0.81 kg/year. The emi...

The aim of the current investigation was to explore the lateral stiffness of different sports wheelchair wheels available to athletes in 'new' and 'used' conditions and to determine the effect of (a) stiffness, (b) tyre type (clincher vs. tubular) and (c) tyre orientation on the physiological and biomechanical responses to submaximal and maximal effort propulsion specific to wheelchair basketba...

Anti-lock Braking System (ABS) is the most important active safety system for passenger cars, but unfortunately the literature is not really precise about its description, stability and performance. This research improves a five-phase hybrid algorithm based on wheel deceleration and validate it on a tyre-in-the-loop laboratory facility. Five relevant effects are modelled so that the simulation ...
