this paper presents a wireless surface acoustic wave (SAW) pressure sensor on 41YX LiNbO3 for tire pressure monitoring system (TPMS) application, in which a reflective delay line composed of an interdigital transducer (IDT) and several reflectors was used as the sensor element. Using the coupling of modes (COM), the SAW reflective delay line was simulated, and the optimal design parameters were...

Modern vehicles offer a raw territory for designing security solutions as the over-increasing design complexity demanded massive advances in electronics in the absence of a crisp vision over the adversary model. The vehicle Tire Pressure Monitoring System (TPMS) is a sub-system that recently triggered some attention in the light of several reported attacks. In this work we start from analyzing ...

In this paper a new approach is presented based on evolutionary polynomial regression (EPR) for modelling of soil–water characteristic curve in unsaturated soils. EPR is an evolutionary data mining technique that generates a transparent and structured representation of the behaviour of a system directly from data. This method can operate on large quantities of data in order to capture nonlinear...

The relationship of serum colloid osmotic pressure (COP) and pulmonary artery wedge pressure (PAWP) to pulmonary edema and mortality was investigated in 76 critically ill patients. Forty patients suffered from circulatory shock and 36 dId not. The COP-PAWP gradient and radiographic evidence of pulmonary edema were measured at the time of diagnosis. The COPPAWP gradient was markedly decreased in...

Large strains in semiconductors are expected to be more common in future electronic devices utilizing nanostructure components. Hydrostatic pressure (HP) and uniaxial stress (US) loading have inherent limitations for probing the desired strain conditions. Uniaxial strain loading, achieved in dynamic compression experiments, is particularly attractive for attaining well-defined, large strains an...

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...

In many surveys, Americans identify invasion of privacy as a primary concern. Nonetheless, newer electronic technologies, such as biometric monitoring, Web site tracking, vehicle tracking, basket-level purchase tracking, charge card usage recording, personal information database sales, release of government data to private corporations, facial identification, DNA testing and record keeping, sma...

Experts from the European Society of Hypertension prepared this position paper in order to summarize current evidence, unmet needs and practical recommendations on the application of percutaneous transluminal ablation of renal nerves [renal denervation (RDN)] as a novel therapeutic strategy for the treatment of resistant hypertension. The sympathetic nervous activation to the kidney and the sen...

Occurrence of top down and bottom up fatigue cracking in asphaltic pavements is common. Conventional pavement analysis methods ignore the existence of cracks in asphaltic layers. However, it seems that the responses of cracked pavement would not be the same as a pavement without crack. This paper describes effects of crack type, position and length, and vehicles tire inflation pressure and axle...

A new planning method for optimal cooperative control of heterogeneous multi-vehicle systems is investigated which enables to account for each vehicle’s nonlinear physical motion dynamics in a structured environment as well as for connectivity constraints of wireless communication. A general formulation as nonlinear hybrid optimal control problem (HOCP) is presented. A transformation technique ...
