We study straight-line drawings of non-planar graphs with few slopes. Interval graphs, co-comparability graphs and AT-free graphs are shown to have have drawings in which the number of slopes is bounded by the maximum degree. We prove that graphs of bounded degree and bounded treewidth have drawings with O(log n) slopes. Finally we prove that every graph has a drawing with one bend per edge, in...

non-somatic causes of pain may aggravate painful complaints and complicate the conservative management of diseases such as lumbo-sacral disk root disease. the two-point discrimination test has been used for assessment of diseases, which change patients' skin sensation. this study aims to find out how applicable is two-point discrimination test in the conservative treatment of lumbo-sacral disk ...

With rising trading volumes in domestic and cross-border security transactions, risks faced by global financial firms and markets are increasing. To manage settlement risks and maintain competitiveness in global financial markets, the U.S. Security and Exchange Commission (SEC) has decided to shorten the settlement cycle of security transactions from the current T+3 to T+1. As a result, key pla...

Let G be a cycle-free connected straight-line graph with predefined edge lengths and fixed order of incident edges around each vertex. We address the problem of deciding whether there exists a simple polygon P such that G is the straight skeleton of P . We show that for given G such a polygon P might not exist, and if it exists it might not be unique. For the later case we give an example with ...

With rising trading volumes in securities transactions and increasing risks faced by global financial firms and markets, STP (Straight Through Processing) is internationally recognized by the securities industry, which is to manage securities trades throughout the trade lifecycle automatically and without human intervention. However, while attempting to achieve STP, care must be taken to ensure...

“Driven by a desire to get paid more quickly, companies are moving more of their invoices and payment to the internet. Businesses care more about faster cash flow than they do about cutting costs.” (GartnerGroup, 2001). Electronic Invoice Presentment and Payment (EIPP) is targeted to the needs of corporates and can be integrated with e-marketplaces and B2B financial settlement for bank-neutral ...

We propose a method for computing acute (non-obtuse) triangulations. That is, for a given two dimensional domain (a set of points or a planar straight line graph), we compute a triangulation of the domain such that all angles are less than (or less than or equal to) π/2. This leads to the first software to compute such triangulations.

Electronic Invoice Presentment and Payment (EIPP) can assist corporate treasurers in cash management and can be integrated with e-marketplaces and other B2B financial settlement activities. Its interactive approach to dispute resolution and robust payment options are critical if corporate financiers are to secure the advantages of B2B marketplaces and straight through processing (STP). Cash man...

Prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. A proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. The main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...
