asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. this is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. this paper presents the evaluation of fatigue behaviour of nano reinforced stone mastic asphalt mixtures. fatigue...

The objective of this study is to investigate the combustion in a pilot-ignited supercharged dual-fuel engine, fueled with different types of gaseous fuels under various equivalence ratios. It is found that if certain operating conditions are maintained, conventional dual-fuel engine combustion mode can be transformed to the combustion mode with the two-stage heat release. This mode of combusti...

cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. during such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. therefore, to design and dev...

data envelopment analysis (dea) has been proven as an efficient technique to evaluate the performance of homogeneous decision making units (dmus) where multiple inputs and outputs exist. in the conventional applications of dea, the data are considered as specific numerical values with explicit designation of being an input or output. however, the observed values of the data are sometimes imprec...

background: a major hurdle to improved in vitro fertilization (ivf) success rate is defective endometrial receptivity and implantation. various techniques have been advocated to increase implantation while reducing side effects. currently, embryo transfer (et) is performed blindly without direct visualization. as such, we sought to develop a technique utilizing a flexible minihysteroscope with ...

This paper describes a recently introduced vector-valued representation of fundamental frequency variation – the FFV spectrum – which has a number of desirable properties. In particular, it is instantaneous, continuous, distributed, and well-suited to application of standard acoustic modeling techniques. We show what the representation looks like, and how it can be used to model prosodic sequen...

A flexible sensor interface integrated into different commercial face masks can be used to measure breathing patterns, skin temperature, physical activity and the fit of mask itself.
