- We summarise our experiences of a number of demonstrators and simulation experiments designed to test the feasibility of using artificial decision making agents in real-time domains, and comment on the significance of our results to autonomous artificial agent action patterns in markets. Our main hypothesis is that the use of norms can extend the capability of artificial decision makers beyond what is obtained from implementing individual utility maximisers in keeping with rational choice theory.

- We report the growth, electronic structure, and in-plane magnetic properties of pulsed laser deposition grown 2D superlattice structures [Pr 0.7Ca 0.3MnO 3/SrTiO 3] 15 and [Pr 0.5Ca 0.5MnO 3/SrTiO 3] 15 on (001) oriented SrTiO 3 and LaAlO 3 single crystal substrates. The x-ray reflectivity measurements reveal well-defined interfaces between the manganite and titanate layers along with the existence of Kiessig fringes, providing the evidence for the smooth periodic superlattice structure. The reciprocal space mapping provides signature of tetragonal distortion in all the superlattices. The electronic structure determined from the x-ray photoelectron spectroscopy reveals divalent Sr and Ca, tetravalent Ti, and mixed valent Mn with a pronounce shift of binding energy peaks toward the higher energy side in the superlattices grown on (001) oriented LaAlO 3 as compared to those grown on SrTiO 3. These superlattices exhibit highly anisotropic ferromagnetic character. We used the law of approach to saturation to determine the anisotropy field (H K) and cubic anisotropy constant ( K 1) for all the investigated superlattices. This analysis yields the highest H K similar to 9kOe and K 1 similar to 8 x 10 5erg/cc for the [Pr 0.7Ca 0.3MnO 3/SrTiO 3] 15 superlattice system. Furthermore, significant enhancement of the overall magnetic moment and a decrease in T C ( < 100K) was observed in the case of LaAlO 3 grown superlattice, which indicates a substantial role of residual elastic strain on the magnetic ordering. Our results indicate that the strain induced elongation of MnO 6 octahedra leads to finite possibility of non-orthogonal overlapping of orbitals in the presence of large crystal field splitting of e g levels, which, in turn, causes suppression of the ferromagnetic double exchange interaction.

- Purpose-The purpose of this paper is to provide an overview of the Sender Policy Framework (SPF) and discuss its merits for adoption as an anti-phishing mechanism. Design/methodology/approach-All of the active domains in the se zone were probed to determine if they have an SPF-policy. This data collection step is combined with a theoretical discussion of the SPF standard and related initiatives. Findings-This paper finds that the adoption ratio is very low. Few seem to be interested in deploying it, despite it being designed for easy adoption and being consistently implemented in several popular anti-spam solutions. Practical implications-The paper shows that despite the low adoption-ratio the standard merits implementation by IT/IS managers and software vendors. Originality/value-This paper analyzes the adoption ratio, which is valuable both for software vendors and endorsers of the standard. It also provides an over-view of the standard itself as an attempt to avoid common misconceptions about the role of the standard and its relation to other anti-spam initiatives.

- The use of fiber reinforced polymer (FRP) laminates to strengthen and repair of steel beams has increased during the last decade and is tending to replace traditional methods, such as welding or bolting of additional steel plates. In this context, one of the issues, which require more research, is design of adhesive joints used to bond FRP laminates to steel substrates. This paper is mainly concerned with evaluation of damage mechanics-based approaches to predict the strength of adhesive joints used to bond FRP laminates to steel beams. Adhesively bonded CFRP/steel double-lap shear specimens are numerically modeled using cohesive zone modeling (CZM) and the results are compared with experiments. The input cohesive material data are obtained from three series of experiments. The results indicate that the proposed methodology to obtain fracture data results in good predictions using CZM. The prediction method presented in this paper could be used in practice to determine the strength of the adhesive joints in FRP bonded steel beams.
