Today scientists are producing large volumes of data that they wish to explore and visualize. In this paper we describe a system that combines range-based queries with fast lookup to allow a scientist to quickly and efficiently ask “what if?” questions. Unique to our system is the ability to perform “cumulative queries” that work on both an intraand inter-time step basis. The results of such qu...

Facebook has established itself as one of the major players in social networking, claiming that it helps members connect and share with the people in their lives. But what if the people you want to connect and share with are your artistic collaborators? Can Facebook be used creatively, as a collaborative artistic environment? This paper explores the creative use of Facebook as a tool for creati...

Euthanasia remains a controversial topic in Canada. One of the major arguments in favour of euthanasia is that it supports the patient’s autonomy and expressed wishes [1-3]. Numerous studies confirm that end-of-life patients place a high level of importance on the respect of their autonomy and wish to decide “when” and “how” they die [4-6]. Unfortunately, these studies do not provide any inform...

System Approach Modelling Applied to the Eluxyl Process — The Eluxyl process achieves paraxylene separation to other xylenes and ethylbenzene. Eluxyl is a simulated moving bed process that requires a fine tuning to produce paraxylene at a very high level of purity, up to 99.90%. A numerical model has been developed in parallel with the process. Objectives are to help tuning, to help design of a...

In this paper, we present the modeling, validation, and verification of an industrial protocol for constraint-based path computation, called PCEP. From the PCEP specification defined by IETF, we divide the functionalities of PCEP into two parts: application and protocol. The protocol part of PCEP is then described in the IF language which is based on communicating timed automata. A number of ba...

Tcl[1] is an interpreted high level language suitable for scripts, small scale systems, prototypes and embedding in larger applications. C++ is a powerful compiled language that provides support for object oriented programming and is suitable for building large complex systems. But what if you could move from C++ to Tcl and back again with the ease of an object reference and a dynamically bound...
