abstract: in this paper, an exergy analysis approach is proposed for optimal design of distillation column by using simulated annealing algorithm. first, the simulation of a distillation column was performed by using the shortcut results and irreversibility in each tray was obtained. the area beneath the exergy loss profile was used as irreversibility index in the whole column. then, first opti...

I wonder if you read about Graham Hill lobbying the Prime Minister? Mr. Hill was complaining about the unsuitable motor tricycles that are issued to disabled haemophiliacs?and he ought to know what is safe to drive. In the deputation with him were members of the Haemophilia Society who pointed out that nearly half of the haemophiliacs who took part in a survey last year now suffered serious int...

The 8th ICN: The largest item looming on the agenda for the ISN is our upcoming Congress in Vancouver (July 22-27). I can tell you that we are in excellent hands with Barb Beltz chairing the Congress Committee and Cathy Rankin as the Chair of the local organizing committee. Ron Harris-Warrick and Sten Grillner are the Congress Vice-Chairs. These folks, with excellent advice from the membership ...

The undisrupted operation of logical structures and services is a crucial requirement in modern day communication networks. As the vertices and edges of the network may occasionally fail or malfunction, it is desirable to make those structures robust against failures. Fault-Tolerant (FT) Logical Network Structures are low cost high resilient structures, constructed on top of a given network, th...

This paper presents a method for real-time rendering of a neocortical column in the mouse brain with 10000 individually simulated neurons, as implemented in the software GabrielStudio (TM). It also presents how the same system is used to create movie sequences of scripted camera keyframes for high resolution outputs. The current system is running on an SGI Altix Prism Extreme with 16 parallel g...

Since the introduction of catalysts and reagents on solid-support, researchers have developed new reaction systems to take advantage of their insoluble nature by designing multistep reaction sequences, high-throughput purification techniques, and combinatorial synthesis methods. The continuous flow system is one of these advancements and represents the foundation of a new technique termed seque...

It has recently been shown that a class of secreted proteins — the Dickkopfs — are released by the Spemann organizer of Xenopus and are potent antagonists of Wnt signaling [1]. Although it has been reported that the Dickkopf (Dkk) proteins contain two cysteine-rich domains, no direct functional or structural conclusions have been drawn from their sequences. The role of Wnt signaling in animal d...

We consider orthogonal upward drawings of directed acyclic graphs with nodes of uniform width but node-specific height. One way to draw such graphs is to use a layering technique as provided by the Sugiyama framework [34]. To overcome one of the drawbacks of the Sugiyama Framework, namely, unnecessary edge crossings caused by an unfortunate layer assignment of the nodes, Chimani et al. integrat...

This Letter makes some observations about [2] that further support the distinction between an interval type-2 fuzzy set (IT2 FS) and an interval-valued fuzzy set (IV FS), points out that all operations, methods and systems that have been developed and published about IT2 FSs are, so far, only valid in the special case when IT2 FS = IVFS, and suggests some research opportunities.
