Deposits of the Warchha Sandstone in the Salt Range, Pakistan are characterised by a range of fluvial facies and architectural elements that together preserve a record of both the proximal and distal parts of a meandering river system that drained the northern margin of Gondwanaland. Several fining-upward cycles are recognised and completely preserved cycles can be divided in to three parts; a ...

We describe an implementation of the Hopcroft and Tarjan planarity test and em bedding algorithm The program tests the planarity of the input graph and either constructs a combinatorial embedding if the graph is planar or exhibits a Kuratowski subgraph if the graph is non planar

The South Saskatchewan River has a long term average discharge of 275 m3/sec, with flood peaks in the range of IS00 to 3800 nP/sec. South of Saskatoon, the four major types of geomorphological elements recognised are channels, slipfacebounded bars, sand flats and vegefated islands and floodplains. Major channels are 3-5 m deep, up to 200 m wide, and flow around sand flats which are 50-2000 m lo...

In this paper, we describe a new technique for the automatic orientation of bedding in drill core from digital images. Images are planar pictures of the drill core, and we show that it is possible to determine layer orientation without rotating the core on the full circumference. More precisely, we show that angle information can be extracted by applying image processing and a mathematical desc...

Considering the network structure is one of the new approaches in studying stochastic PERT networks (SPN). In this paper, planar networks are studied as a special class of networks. Two structural reducible mechanisms titled arc contraction and deletion are developed to convert any planar network to a series-parallel network structure.&#10In series-parallel SPN, the completion time distribution...
