On Sum Coloring of Graphs Mohammadreza Salavatipour Master of Science Graduate Department of Computer Science University of Toronto 2000 The sum coloring problem asks to nd a vertex coloring of a given graph G, using natural numbers, such that the total sum of the colors of vertices is minimized amongst all proper vertex colorings of G. This minimum total sum is the chromatic sum of the graph, ...

The aim of this paper is to develop a strategic plan for selecting the best options for the supply of raw material to feed paper producing plants. The decision-making is examined within the framework of benefits, opportunities, costs, and risks (BOCR). A hierarchy is used to prioritize the BOCR, using the Analytic Hierarchy Process (AHP) ratings approach. A control hierarchy is then created and...

Death and aging anxieties are related to higher psychological distress, but no study has examined whether these relationships are moderated by emotional complexity, an important indicator of adaptive emotional regulation among older adults. Participants (N = 188; mean age = 57; range = 29–100) rated their death and aging anxieties, general psychological distress, and reported their emotions on ...

We present Nexus – a robust and scalable middleware for decentralized service-oriented information fusion. As a project in the UK Ministry of Defence Defence Technology Centre, Nexus is driven by the goals of Network Enabled Capability (NEC). It provides support for discovering, structuring and fusing information – key operations enabling the NEC vision. It is built on top of three key concepts...

Not really. When the computer was invented, it was a great idea to calculate and store data. Internet complemented the greatness of this technology.

Personal privacy is a strong sense of human being. Wearing clothes, er...

The 19th annual TEX Users Group Meeting took place in Toruń , Poland, in August of this year. The following is the impression of the authors who tried to attend all the talks. Unfortunately a couple of the talks were not attended by either of the authors. Apologies to those authors. Daniel Taupin described his LATEX to RTF converter, ltx2rtf. His problem is that he wants to transfer LATEX docum...

The growing demand for high-bandwidth communication between integrated circuits calls for large numbers of high-speed inputs and outputs (IOs) per chip. IO data rates have increased to the point where electrical signaling is now limited by the channel properties. In order to achieve multi-Gb/s data rates, complex designs that equalize the channel are necessary. Using optics for chip-to-chip int...

1. introduction the shahnameh opens with a preface which probably did not exist prior to ferdowsi. even if such a thing existed, it must have been different from the present introduction. putting this aside, the rest of the shahnameh has a clear beginning and ending. this has helped critics to determine the structure of the work as a whole by its content. however, we believe the shahnameh inclu...
