In a search for spectral parameters that can be used to distinguish and to model fricatives, spectral moments, dynamic amplitude, and slope above maximum amplitude were computed for a fricative corpus including sustained fricatives at di erent e ort levels, and fricatives in vowel context. Moments varied signi cantly by frequency range used in computation. M3 appeared to vary the least across f...

Should a rm favor a weaker or stronger employee in a contest? Despite a widespread emphasis on rewarding the best employees, managers continue to tolerate and even favor poor performers. Contest theory reveals that evenly matched contests are the most intense, which implies that a contest designer can maximize each player's e ort by arti cially boosting the underdog's chances.

We provide a cultural explanation to the phenomenon of corruption in the framework of an overlapping generations model with intergenerational transmission of values. We show that the economy has two steady states with di erent levels of corruption. The driving force in the equilibrium selection process is the education e ort exerted by parents which depends on the distribution of ethics in the ...

This paper documents the development, validation, and re nement of analytic deposition models for automotive spray painting, based largely on experimental work conducted in conjunction with the Ford Motor Company. This work, part of a larger ongoing collaborative e ort with the Ford Motor Company, has the goal of developing practical and eÆcient trajectory planning tools for automotive painting...

Road traffic accidents account for approximately 3000 deaths on a daily basis, and 50 million injuries and 1.2 million deaths each year. In low-income and middle income countries, road traffic accidents account for 85% of deaths and 90% of annual disability. Casualties of this magnitude are a serious problem throughout the world and create a significant impact on society. In addition, neurologi...

Injuries caused by traffic accidents cause many deaths and disabilities children. Road traffic injuries are the main cause of death between the ages of 15 and 19 years and is the second cause of death among 5 to 14 year olds. Children's attitudes about driving and safe use of roads formed in 11 years. Road traffic injuries is one of the five cause of disability among children. Most victims betw...

Worldwide, more than 185,000 children under 18 years die from road traffic accidents annually (each four minutes a child death occurred due to road crashes); with most casualties from developing countries. 95% of road traffic fatalities among children occur in developing countries. Many more children are injured, often severely, and suffering from different disabilities. Road accidents cause ex...

Budapest Közút is developing ROad Data Information System based on mobile laser scanning since 2013. All public roads (cca. 5000 km) are surveyed by MLS (Riegl VMX450) in survey grade accuracy and all visible road assets has been digitized and loaded to a complex 3D GIS environment. Since the first full coverage had been done in 2014 the whole city has also been updated - being one of the few l...

To cope with the urban congestion problem resulted from rapid urbanization some cities are successfully using Electronic Road Pricing policy as a demand management measure. In 1982, Hong Kong Governmenttook initiative to experiment electronic road pricing in Hong Kong. Though, the project outcome reveals that Electronic Road Pricing could bring tremendous economic, social and environmental bene...
