In recent years a huge number of online auctions that use Multi Agent systems have been created. As a result there are numerous auctions that provide the same product. In this case each customer can buy a product with the lowest possible price. But searching between auctions in terms of finding the suitable product can be time consuming for consumers and also providing products in different markets is a difficult task for suppliers. So the need for an autonomous agent in these types of markets is deeply felt. On the other side the structure of an auction mechanism that provides the environment for traders to operate their trades is vital. Despite all the research that has been done about online auctions, most of them were about single markets. But in real world the stocks and commodities of companies are listed and traded in different markets. There is a growing tendency towards research about online auctions and Market Design. Particularly in recent years CAT (CATallactics) game has provided an important opportunity to develop and test new techniques in this field. In this paper after introducing CAT game and PersianCAT agent, we want to challenge the conventional accepting policy used in stock markets like New York Stock Exchange and provide a better solution that improves the general performance of the markets.

The purpose of this pilot study was to explore the feasibility of using hand drawn images to identify symbol components for incorporation into warning symbol design software. This software will use an interactive evolutionary computation (IEC) algorithm to generate and evolve symbols mathematically described by a set of numerical parameters. Therefore, participants (N = 100) ages 19-43 (x = 23.2) were recruited to determine these symbol design parameters. Participants were invited to hand draw warning symbols for three referents: fall from elevation, hearing protection, and hazardous atmosphere. A panel of design engineers determined 27 attributes were present in the fall from elevation, 19 in the hearing protection, and 25 in the hazardous atmosphere images. A direct clustering algorithm was used to determine which attributes, or symbol parameters, were most commonly present or conspicuously absent among the clustered image families. For the fall from elevation, hearing protection and hazardous atmosphere referents, the clustering algorithm identified six, four and four symbol parameters, respectively, primarily responsible for distinguishing one drawn symbol from another. Thus, these parameters will be included as evolvable genes in the IEC software.
In wireless sensor networks, the network state beacon exchange rate is vital to determine the quality of service (QoS) performance of network state. It is important to schedule this parameter adoptively due to the dyn...

The use of Field Effect Diode (FED) together with double gate (DG) silicon on insulator (SOI) MOSFET for implementing Variable Gain Amplifier (VGA) in Automatic Gain Control (AGC) systems are investigated in this paper. These VGA circuits show better characteristics in terms of power and bandwidth compared with MOSFET-VGA. Using the FED and DG SOI-MOSFET devices, leads to more flexibility in terms of better gain control, performance improvement, and power consumption reduction.
An integrated, compact and upgradeable bidirectional multiplexer/ demultiplexer and Add-drop multiplexing based on array of ring resonators is proposed. The proposed structure is realized using basic elements in optic...

This paper describes E-TCP, an evolutionary computation approach for TCP. It is designed to avoid heavy congested areas by using an evolutionary path adaptation of the outgoing packets. E-TCP is evaluated through simulations using ns2. E-TCP delivers a significant performance improvement for bulk data transfers. Copyright 2008 ACM.
