  • ALKION column and eluant system

    Introduction: The stationary phase in the ALKION column is a rigid, non-porous polymeric phase that is surface sulfonated. The two modes of separation are ion-exchange and moderate partitioning. The low capacity of the ion-exchange resin makes it an ideal phase for the separation of strongly basic and positively charged compounds. The reversed-phase character allows for ...

  • Systems engineering education for public policy

    Developments in public policy create new challenges for engineering and engineering education. Analytic and synthetic skills are required to handle the substantive complexities of policy problems, and managerial skills are necessary to design and guide the human interaction processes needed for knowledge integration, multi-party learning and negotiation, and decision-making. The resulting ...

  • Behavioural types determining economic systems

    The paper formulates an analytical framework that considers the roles of a changing distribution of agents on behavioural settings with distinct behavioural traits and of their interactive behaviour across many settings, in pushing the economic system towards a distinct behavioural type. The framework is elaborated to distinguish between basically different economic systems along distinct ...

  • Gaseous release in LiNH2–MgH2 systems

    Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, ...

  • Boiling water reactors as dynamic complex systems

    The research studied and analysed the nonlinear behaviour of Boiling Water Reactors (BWRs) using a new analytical reduced-order model. This model was applied to analyse global and regional oscillations in BWRs. Stability and semi-analytical bifurcation analyses were performed using this model in conjunction with the bifurcation code BIFDD to determine the stability limits for both in-phase and ...

  • Reallocation of system mass and stiffness for achieving target specifications

    The development of a system model involves the assemblage of many important components from a dynamic standpoint. The performance of the system is dependent on the dynamic characteristics of each of the components. In an attempt to improve the overall system characteristics, targets are typically specified at the system level. The determination of the component characteristics to achieve these ...

  • Connectionist expert systems for analysis of health problems associated with industrial activity and electricity generation systems

    Connectionist expert systems (neural networks) have the power to solve structurally ill-defined problems. Health-environmental interactions are inducing types of non-linear system behaviour and are often difficult to study by existing analytical methods. This paper introduces a new way to portray the complex relationship between low level pollution, the health of the population and the risk ...
