Layers in ArcScene containing polygon features can be extruded to create 3D blocks for display in the current scene. While this is useful for representing flat-roofed buildings within ArcScene it does not create a new, 3D shapefile and cannot create buildings with peaked or curved roofs. A method to create 3D shapefiles representing buildings with complex roofs and then export these objects to ...

This paper is published by Euroheat & Power. Our aim is to inform about district heating and cooling as efficient and environmentally benign energy solutions that make use of resources that otherwise would be wasted, delivering reliable and comfortable heating and cooling in return.

We prove equivalence of certain axiom sets for a ne buildings. Along the lines a purely combinatorial proof of the existence of a spherical building at in nity is given. As a corollary we obtain that being an a ne building is independent of the metric structure of the space.

Measurements of thoron (""Rn) have been performed in some 90 buildings during 1992 and 1993, as parts of two different investigations. The measurements were performed in order to form a basis for assessing the risk for high thoron levels indoors in Sweden. In the first study thoron progeny measurements were undertaken in 53 dwellings and 7 workplaces at 13 different locations in south and centr...

Introduction The reinforced concrete tilt-up building is the most popular form of light industrial and low-rise commercial construction in the Western United States and is a significant portion of new construction nationwide. This popularity is primarily driven by the construction speed and economical nature of tilt-up construction. Architectural acceptance has become more widespread as tilt-up...

C ivil engineers are often very conservative in how they pursue their profession-and for good reason: If their designs don't work, things can fall down and kill people (as the recent bridge collapse in Minnesota so clearly demonstrates). Following novel approaches increases the probability of making such disastrous mistakes. It can therefore be prudent to build on designs that are known to func...

ii Abstract When a given 3D city model, consisting of mainly buildings and roads, is viewed at reduced scale, its objects not only become smaller but tend to conflict due to small area available. Generalization plays an important role to overcome these effects and helps in preserving the required legibility. Various operations are performed during generalization on these objects. One of the pri...

Risk factors for asthma, allergy and eczema were studied in a stratified random sample of adults in Stockholm. In 2005, 472 multifamily buildings (10,506 dwellings) were invited (one subject/dwelling) and 7,554 participated (73%). Associations were analyzed by multiple logistic regression, adjusting for gender, age, smoking, country of birth, income and years in the dwelling. In total, 11% had ...
