This work presents a convenient and non-contact acoustic sensing approach for measuring ground vibration. This approach, which uses an instantaneous dynamic tire pressure sensor (DTPS), possesses the capability to replace the accelerometer or directional microphone currently being used for inspecting pavement conditions. By measuring dynamic pressure changes inside the tire, ground vibration ca...

Forward integration has been explained both as a method of achieving monopoly power and as a source of greater efficiency [6, 16]. An efficiency perspective underpins the work of Chandler and Williamson who regard vertical integration, particularly into distribution, as a crucial step in the creation and success of large firms. While their views have moved closer, Chandler and Williamson emphas...

Simulation is an important aspect to consider when designing an inspection system based upon machine vision. The tire inspection system uses thermal cameras to inspect the surface of a tire. The simulation of a tire inspection system can yield an optimal set of parameters for a thermal camera, or given a specific thermal camera provide information on the optimal placement of the camera. Since t...

For the design of an antenna that will be directly attached to a car tire, the proximity effects due to the tire have to be considered. Measurements are performed on a dipole antenna that is mounted at the inside of the tire tread to determine the change in input impedance and resonant frequency caused by the dielectric rubber material and the metal reinforcement of the tire. A differential mea...

Laboratory studies were conducted to investigate scrap-tire-shreds as a potential alternative to conventional gravel in the drainage layer of leachate collection system at the base of landfill. Performance of various physico-chemical characteristics of leachate after passing it through combined bed of scrap-tire-shreds and gravel for different combinations of thickness of scrap-tireshreds and g...

hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. today this technology has found its place in the array of pharmaceutical manufacturing operations. melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

Plus-sizing, or the fitting of larger diameter rims and lower profile tires to vehicles, continues to be a significant commercial force in the tire marketplace. When offering plus-size fitments to customers, many sellers simply offer “what fits” on a given vehicle. However, the various choices made by the seller, such as wheel width, wheel offset, inflation pressure, and so on, have the potenti...

An investigation was conducted to determine the influence of recycled scrap tire rubber on the engineering properties of controlled low strength material (CLSM). With control over the ultimate compressive strength of CLSMs being key for applications such as backfilling utility trenches where re-excavation is often necessary, incorporation of scrap tire rubber into the CLSM mixture is a viable w...

Active steering systems can help the driver to master critical driving situations, for example aquaplaning and -split braking. In these situations it is likely that the tires reach their performance limits, where nonlinear effects like saturation play an important role. Tires are the part in vehicle dynamics afflicted with the highest degree of nonlinearity – due to saturation – and uncertainty...

Cryogenic mechanical alloying (CMA) is investigated as a viable strategy by which to produce highly dispersed blends composed of thermoplastics and tire, thereby providing a potentially new route by which to recycle discarded tires. Morphological characterization of these blends by near-edge X-ray absorption ®ne structure (NEXAFS) microscopy demonstrates that, upon CMA, ground tire is highly di...
