bam, which is located in the south eastern part of iran, east of kerman province, is a desert city with its special natural and cultural landscapes, which is different in many ways from all other desert cities in iran .there has always been a balance between cultural and natural elements in bam. one of the unique natural elements of bam is its rich underground water reservoirs, which originates...

We show how layering in communication software violates the principle of separating concerns. Examples illustrate that layering couples receiver-and sender functions, sharing message headers among layers creates dependencies between layers that largely compromise re-usability, QoS management is scattered over all layers, and layers are tightly coupled with the sub-system that executes it. Layer...

Perhaps Functional Grammar’s most distinctive feature is its extensive use of the so-called layered structure of the clause (LSC). The LSC is used as both a descriptive and explanatory construct, dividing the linguistic world into various hierarchically related layers, each with concomitant operators and satellites. Since Hengeveld’s original Layers and Operators article (1989), the principle o...

We present heat-capacity data detailing the evolution of the first six layers of argon adsorbed on graphite foam. The second and third layers have liquid-solid-gas triple points similar to the first layer. These layers exhibit a phase diagram consisting of two-dimensional solid, liquid, and gas phases on top of a solid film. Above the temperatures of the individual-layer triple points, the melt...

Airborne LiDAR point cloud of a forest contains three dimensional data, from which vertical stand structure (including information about under-story trees) can be derived. This paper presents a segmentation approach for multi-story stands that strips the point cloud to its canopy layers, identifies individual tree segments within each layer using a DSM-based tree identification method as a buil...

The current Internet is not well suited for the transmission of high quality video such as MPEG-2 because of severe quality degradation during network congestion episodes. One possible solution is the combination of layered video coding with the Differentiated Services (DiffServ) architecture; different video layers are mapped into different priority levels, and packets with different prioritie...
