A Zero-Sum Competitive Multi-Player Game, Ivan W. Guo, Marek Rutkowski
A Zero-Sum Competitive Multi-Player Game, Ivan W. Guo, Marek Rutkowski
Faculty of Engineering and Information Sciences - Papers: Part A
A single period, zero-sum, multi-player game is constructed. Each player can either exit the game for a fixed payoff or stay and split the remaining payoff with the other non-exiting players. The emphasis is put on the rivalrous nature of the payoffs, meaning that the sum of all payoffs is fixed, but the exact allocation is based on the players' decisions. The value at which Nash and optimal equilibria are attained is shown to be unique and it is constructed explicitly.

(Strong) Multi-Designated Verifiers Signatures Secure Against Rogue Key Attack, Yunmei Zhang, Man Ho Allen Au, Guomin Yang, Willy Susilo

Designated verifier signatures (DVS) allow a signer to create a signature whose validity can only be verified by a specific entity chosen by the signer. In addition, the chosen entity, known as the designated verifier, cannot convince any body that the signature is created by the signer. Multi-designated verifiers signatures (MDVS) are a natural extension of DVS in which the signer can choose multiple designated verifiers. DVS and MDVS are useful primitives in electronic voting and contract signing. In this paper, we investigate various aspects of MDVS and make two contributions. Firstly, we revisit the notion of unforgeability under rogue …

Application Of Multi-Agent System For Preventing Power Interruption In A Large Power System, S R. Islam, Darmawan Sutanto, K M. Muttaqi

This paper presents an emergency control approach for preventing wide spread power interruption using multi-agent system. The proposed control algorithm is based on decentralized architecture of intelligent agents to achieve fast and accurate response when a catastrophic disturbance is identified in the system. By dividing the network into several areas, the voltage instability problem can be localized and countermeasures can be directed to the most affected area by the authorized local agent. This facilitates quick decision making within the system. The effectiveness of the proposed technique has been proved by a simulation of IEEE 57 bus test power system.
A Multi-Agent Solution To Distribution System Management By Considering Distributed Generators, Fenghui Ren, Minjie Zhang, Darmawan Sutanto
A Multi-Agent Solution To Distribution System Management By Considering Distributed Generators, Fenghui Ren, Minjie Zhang, Darmawan Sutanto

A traditional distribution network carries electricity from a central power resource to consumers, and the power dispatch is controlled centrally. Distributed generators (DGs) emerge as an alternative power resource to distribution networks at a smaller and distributed scale, which will bring benefits such as reduced voltage drop and loss. However, because most of high penetration DGs are not utility owned and characterized by high degree of uncertainty such as solar and wind, the distribution network may perform differently from the conventionally expected behaviors. How to dynamically and efficiently manage the power dispatch in a distribution network to balance the supply …
Development Of Sipm-Based Scintillator Tile Detectors For A Multi-Layer Fast Neutron Tracker, R Preston, J Jakubek, D Prokopovich, J Uher
Development Of Sipm-Based Scintillator Tile Detectors For A Multi-Layer Fast Neutron Tracker, R Preston, J Jakubek, D Prokopovich, J Uher
Faculty of Engineering and Information Sciences - Papers: Part A
We are developing thin tile scintillator detectors with silicon photomultiplier (SiPM) readout for use in a multi-layer fast-neutron tracker. The tracker is based on interleaved Timepix and plastic scintillator layers. The thin 15 x 15 x 2 mm plastic scintillators require suitable optical readout in order to detect and measure the energy lost by energetic protons that have been recoiled by fast neutrons. Our first prototype used dual SiPMs, coupled to opposite edges of the scintillator tile using light-guides. An alternative readout geometry was designed in an effort to increase the fraction of scintillation light detected by the SiPMs. The …
Multi-Level Controlled Signature, Pairat Thorncharoensri, Willy Susilo, Yi Mu
Multi-Level Controlled Signature, Pairat Thorncharoensri, Willy Susilo, Yi Mu
Faculty of Engineering and Information Sciences - Papers: Part A
In this work, we present and establish a new primitive called Multi-level Controlled Signature. This primitive allows a signer to specify a security level to limit the verifiability of the signature. This primitive works as follows. Without losing generality, we assume the security levels of a group of users are defined in ascending order, where “A” represents the lowest security level and “Z” represents the highest security level, respectively. When a signer signs a message by specifying a security level “C”, all users who have a security level greater than “C” will be able to verify while other users whose …
