Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...

A new methodology is presented that describes the density of urban systems. By combining highly detailed height measurements with amongst others topographical data we are able to quantify the urban volume. This new approach is tested in two separate case-studies that respectively relate to the temporal and spatial dimension of the urban environment. In the first study the growth of the city of ...

Trees and forests are, because of seasonal changes and their size, shape, and color, the most prominent elements of urban nature. Their benefits and uses range from intangible psychological and aesthetic benefits to amelioration of urban climate and mitigation of air pollution. Historically the main benefits of urban trees and forests relate to health, aesthetic and recreational benefits in ind...

despite the close relationship between collective memory and urban structure, as the relationship between what is hidden and what is visible, rapid changes throughout the city have caused a disconnection between integrated memories and landscape cohesion. as a context for memories, the historical urban landscape proves valuable. the present research seeks to identify elements and signs in urban...

a 6-year-old lactating holstein cow with a history of repeat breeding syndrome (failed to conceive afterthree artificial inseminations (ai) with fertile semen) was referred to the veterinary teaching hospital of theschool of veterinary medicine, shiraz university. according to the history, neither abnormal clinical signs,nor uterine discharge had been observed subsequent to ai. the cow had show...

Colour and shape are basic characteristics of traffic signs which are used both by the driver and to develop artificial traffic sign recognition systems. However, these sign features have not been represented robustly in the earlier developed recognition systems, especially in disturbed viewing conditions. In this study, this information is represented by using a human vision colour appearance ...

Vitamin A status in a sample of pregnant and lactating women living in several representative regions of Congo was assessed and compared between August and September 2004. This survey was conducted using a randomized two-stage cluster-sampling method with stratification on 90 clusters, each consisting of at least 15 women. Vitamin A status was determined in a total of 1,054 individuals, using t...
