A novel Artificial Life paradigm is proposed where autonomous agents are controlled via geneticallyencoded Evolvable Mathematical Models (EMMs). Agent/environment inputs are mapped to agent outputs via equation trees which are evolved using Genetic Programming. Equations use only the four basic mathematical operators: addition, subtraction, multiplication and division. Experiments on the discre...

In this paper we present an attack which allows fraudulent transactions to be collected from EMV contactless credit and debit cards without the knowledge of the cardholder. The attack exploits a previously unreported vulnerability in EMV protocol, which allows EMV contactless cards to approve unlimited value transactions without the cardholder's PIN when the transaction is carried out in a fore...

INTRODUCTION Nutrition interventions may have favourable as well as unfavourable effects. The Maternal and Infant Nutrition Interventions in Matlab (MINIMat), with early prenatal food and micronutrient supplementation, reduced infant mortality and were reported to be very cost-effective. However, the multiple micronutrients (MMS) supplement was associated with an increased risk of stunted growt...

Motivated by the empirical evidence of the long-range dependency found within the Greek motor insurance market, we formulate a particular stochastic pricing model in a continuous framework. We assume the structure of a competitive insurance market where the business volume of each company is directly related to the existing relativity between the company’s premium and the market’s average premi...

This paper explores the application of noncooperative game theory together with the concept of Nash equilibrium to the investigation of some basic problems on multi-scale structure, especially the meso-scale structure in the multi-phase complex systems in chemical engineering. The basis of this work is the energy-minimization-multi-scale (EMMS) model proposed by Li and Kwauk (1994) and Li, et a...

Continuing a line of work initiated in Boyer et al. (2007), the generalisation of stochastic string distance to a stochastic tree distance, specically to stochastic Tai distance, is considered. An issue in modifying Zhang/Shasha tree-distance for stochastic variants is noted, a Viterbi EM costadaptation algorithm for this distance is proposed and a counter-example noted to an all-paths EM propo...

Abstract Seven-degree-of-freedom redundant manipulators with link offset have many advantages, including obvious geometric significance and suitability for configuration control. Their is similar to that of the experimental module manipulator (EMM) in Chinese Space Station Remote Manipulator System. However, finding analytical solution an EMM on basis arm angle parameterization difficult. This ...

Though discrete particle simulation (DPS) has been widely used for investigating gas-solid flows from a more detailed level as compared to traditional two-fluid models (TFM), it is still seriously limited by the computational cost when large scale systems are simulated. GPUs (graphic processing units), with their massive parallel architecture and high floating point performance, provide new pos...

In this paper we investigate the complex relationship between tweet board literature (like bullishness, volume, agreement etc) with the financial market instruments (like volatility, trading volume and stock prices). We have analyzed sentiments for more than 4 million tweets between June 2010 to July 2011 for DJIA, NASDAQ-100 and 13 other big cap technological stocks. Our results show high corr...
