Activity and Stability Design Principles of Transition Metal Compounds for Decarbonization
… it is crucial to elucidate the activity and stability design principles (i.e., descriptors) of transition metal compounds for these electrochemical systems. Such design principles can offer a mechanistic understanding of the physical origin of their activity and durability and provide new …

Stability design criteria and volt var control for distribution system with single phase solid state transformers
… due to harmonic resonance are observed. A design criterion for solid state transformer during no load conditions has been proposed in order to avoid instability using an impedance-based analysis. Stability assessment is also extended to include the impact of distribution system voltages and …

Computational fluid dynamics modelling of pipeline on-bottom stability.
… and steady current loads which cause pipeline stability problems. Current knowledge and understanding on the pipeline on-bottom stability is based on the research programmes from the 1980s such as the Pipeline Stability Design Project (PIPESTAB) and American Gas Association (AGA) in Joint …

Effects of residual stresses and initial imperfections on earthquake response of steel moment frames
… the Direct Analysis Method (DM) as the standard stability analysis and design procedure. Although the DM has important benefits over conventional stability design methods, the interface between the DM, the AISC Seismic Provisions and the seismic design requirements in ASCE-7 is not fully …

A lumped-parameter model of tire-terrain interactions for off-road vehicles
… the traction control systems, and the electronic stability control have improved vehicle performance and stability. Design and tuning of such control units requires large amounts of trial and error modifications as well as experiments. Therefore the need for accurate and computationally efficient …

Bondcoat developments for thermal barrier coatings
The prime design considerations for modern nickel based superalloys for use in aero gas-turbine engines, are those of mechanical performance, namely good resistance to creep and fatigue with good toughness and microstructural phase stability. Design of the current generation of superalloys has …

Brace Effectiveness of Cross-frame Layout and Connection Design on Skewed Steel Bridges During Construction
… Department of Transportation (KDOT)'s current design practice is to align cross-frames parallel to the skew angle to avoid problems associated with fit-up during erection. The American Association of State Highway and Transportation Officials (AASHTO) provisions for bridges with skew angle …

A Parametric Model for Predicting Submarine Dynamic Stability in Early Stage Design
The goal of this thesis is to develop a dynamic stability and control module that can be used in the concept exploration phase of design. The purpose of the module is to determine the hydrodynamic coefficients/derivatives and stability characteristics of a given design. Two tools, GEORGE and CEBAXI …

Investigation of factors governing the stability of stope panels in hard rock mines in order to define a suitable design methodology for shallow mining operations
Instability in stope panels in shallow mines manifests itself as rockfalls from the hangingwall. Rockfalls from unstable stope panels vary in size from rockfalls between support units, to rockfalls spanning between pillars or solid abutments, to rockfalls bridging several panels and pillars. A …
