A multiple criteria decision analy.is （MCDA） approach is designed for capturing the relative preference information of a decision maker involved in ＇a conflict. More specifically. an MCDA approach based on the outranking method, ELECTRE III, is employ.d for ranking states or possible scenarios in the conflict from most to least preferred, where ties are allowed, for a decision maker according to his or her value sy.tem. To demonstrate how this preference elicitation methodology.can be conveniently.implemented in practice within the framework of the Graph Model for Conflict Resolution, it is applied to a real world water supply.crisis which occurred in the town of North Battleford, located in the Canadian province of Saskatchewan.

Hazardous wastes pose increasing threats to people and environment during the processes of offsite collection,storage,treatment,and disposal.A novel game theoretic model,including two levels,is developed for the corresponding optimization of emergency.logistics,where the upper level indicates the location and capacity.problem for the regulator,and the lower level reflects the allocation problem for the emergency.*** from other works in the literature,we focus on the issue of multi-quality.coverages (full and partial coverages) in the optimization of facility.location and *** be specific,the regulator decides the location plan and the corresponding capacity.of storing emergency.groups for multiple ty.es of hazmats,so to minimizes the total potential environmental risk posed by.incident sites;while the commander minimizes the total costs to provide an efficient allocation *** solve the bi-level programming model,two solution techniques,namely.a KKT condition approach and a heuristic model,are designed and *** proposed model and solution techniques are then applied to a hy.othetical case and a real-world case to demonstrate the practicality.and provide managerial insights.

The perturbation method is applied to investigate the frictionally.excited thermoelastic dy.amic instability.(TEDI) of a functionally.graded material (FGM) coating in half-plane sliding against a homogeneous half-plane. We assume that the thermoelastic properties of the FGM vary.exponentially.with thickness. We also examine the effects of the gradient index, sliding speed, and friction coefficient on the TEDI for various material combinations. The transverse normal stress for two different coating structures is calculated. Furthermore, the frictional sliding stability.of two different coating structures is analy.ed. The obtained results show that use of FGM coatings can improve the TEDI of this sliding sy.tem and reduce the possibility.of interfacial failure by.controlling the interfacial tensile stress.

Problems involving coupled multiple space and time scales offer a real challenge for conventional frame-works of either particle or continuum mechanics. In this paper, four cases studies （shear band formation in bulk metallic glasses, spallation resulting from stress wave, interaction between a probe tip and sample, the simulation of nanoindentation with molecular statistical thermody.amics） are provided to illustrate the three levels of trans-scale problems （problems due to various phy.ical mechanisms at macro-level, problems due to micro-structural evolution at macro/micro-level, problems due to the coupling of atoms/ molecules and a finite size body.at micro/nano-level） and their formulations. Accordingly. non-equilibrium statistical mechanics, coupled trans-scale equations and simultaneous solutions, and trans-scale algorithms based on atomic/molecular interaction are suggested as the three possible modes of trans-scale mechanics.

The excited state of Chlorophy.l a is *** by.ferntosecond transient absorption. The transient absorption spectra of Q band and By.band of Chlorophy.l a in ethanol have been observed. The fast kinetics of Chlorophy.l a which exhibit two ultrafast components were also ineasured. The one is assigned to transient absorption of the inhomogencously.broadened ground state absorption spectrum, while the other is the response of the solvent to the change of the electron configuration in the excited state due to solvation dy.amics of the polar solvent molecules. To understand the anisotropy.of Chlorophy.l a in ethanol, the anisotropy.profile was also performed by.405 nm excitation and found that the anisotropy.profile is 0.143. The possible combination of θda, θdb and η at at excitation of By.band has been simulated.

Despite the great efforts dedicated to metallic glasses （MGs）, their structure still remains a my.tery.to be understood. With comparison to the existing mJciomechanical models, such as the free-volume and shear transformation zone （STZ） models, we first discuss in this article our recently.proposed ＇core-shell＇ model, which contains a solid-like matrix and liquid-like inclusions. This serves as the theoretical basis to understand the structural heterogeneity.in MGs in our analy.ical framework. After that, a scanning ultrafast nanoindentation technique is used to map out the structure heterogeneity.in a Zr-based bulk metallic glass （BMG）. With these ongoing research efforts, we hope that more research work could be stimulated in the pursuit of the structure-property.relation in MGs.
