We define an elliptic equation for Hermitian metrics which is related to the Einstein condition. Solutions to this equation are closely related to Kähler-Einstein metrics, and are automatically Kähler-Einstein when a certain non-positive condition is satisfied by c1(M). Given this, a natural flow equation arises taking Hermitian metrics to Kähler metrics. We prove short time existence and regul...

OBJECTIVE Millions of children leave home in hope of finding a more tolerable life. The study tries to find out the kind of life they lead once out on the streets. METHODS Cross-sectional study of all street boys admitted to a Child Observation Home in New Delhi during specified 6 months. Questions regarding various aspects of survival on streets were asked.

CONTEXT Complete Streets policies guide planning in communities by making the transportation system accommodating to all users including vehicle drivers, pedestrians, and bicyclists, as well as those using public transportation. While the number of Complete Streets policies has increased over the past decade, no research has explored the factors attributing to the widespread diffusion of these ...

City streets in this country represent an annual capital outlay of $3,133 billion, based on 1966 data. This figure is more than one-third of the total annual capital outlay for all streets and highways, $9,123 billion. Another $1,114 billion was spent annually for maintenance of city streets, so $4,247 billion was spent each year on city streets. O f this total $4 billion, $2.5 billion went to ...

OBJECTIVES To compare child pedestrian injury rates on one-way versus two-way streets in Hamilton, and examine whether the characteristics of child pedestrian injuries differ across street types. METHODS The rates of injury per child population, per kilometre, per year were calculated by age, sex and socio-economic status (SES). Child, environment and driver characteristics were investigated ...

A fundamental problem in robotics is to compute a path for a robot from its current location to a given goal. In this paper we consider the problem of a robot equipped with an on-board vision system searching for a goal g in an unknown environment. We assume that the robot is originally located at a point s on the boundary of a street polygon. A street is a simple polygon with two distinguished...

Article history: Received 5 April 2016 Received in revised form 14 September 2016 Accepted 15 September 2016 Available online 15 September 2016 In 2013, San Francisco was one of eight sites funded by Partnership for a Healthier America to implement Play Streets, a smaller-scale Open Streets-type initiative, aimed at increasing physical activity (PA) among children and youth by closing neighborh...

OBJECTIVES To investigate if the population living along streets with high traffic density has a higher prevalence of chronic respiratory symptoms. METHODS A sample of 673 adults and 106 children (0-15 years), living along busy traffic streets in the city of Haarlem was compared with a control sample of 812 adults and 185 children living along quiet streets. Exposed and control streets were s...

Maintaining human thermal comfort (HTC) is essential for pedestrians because people outside can be more susceptible to heat stress and heat stroke. Modification of street microclimates using tree canopy cover can provide important benefits to pedestrians, but how beneficial and under what circumstances is not clear. On sunny summer days, microclimatic measures were made in residential streets w...
