Crash Analysis of Degraded Concrete Containment Structures
… widespread damages to the cask during the tip-over scenario, while the damage is still localized in case of the initial reference concrete. Two main failure modes during tip-over event are concrete crushing and shear banding.

Optical and Plasmonic Properties of Metallic Tip /Surface Junctions
… frequencies. Introducing a nanopraticle or a tip to an infinite metallic surface breaks the continuity of the surface allowing coupling with light. This leads to remarkable nearfield focusing and enhancement at optical resonances through the gap between the metallic nanoparticle/tip and the …

Modelling, design, and control of a spherical rolling robot
… rolling robots offer a number of advantages over traditional wheeled robots. Their geometry allows for increased mobility and the inability to tip over, while their enclosed design provides protection for the electronic and mechanical components driving the robot. However, these advantages …

Games, puzzles, and computation
… the other end of the spectrum, I show that a multiplayer version of Constraint Logic is undecidable. That there are undecidable games using finite physical resources is philosophically important, and raises issues related to the Church-Turing thesis. In the second half of this thesis, I apply the …

High current ion emission in electrohydrodynamic spraying
… of ions from conducting liquids at a capillary tip has traditionally been explained as field evaporation at room temperature from a very small liquid tip, of the order of 10 -20 i. Consideration of the effect of space charge on the fields and force balance at the tip indicates that stable …

Fatigue crack growth (FCG) modeling in the presence of nano-obstacles
… the irreversible interaction of crack-tip emitted dislocations with nano-twins in the vicinity of the crack upon cyclic loading. A method is developed to quantify the irreversibility of slip, and calculate it as a function of the twin lamella thickness and crack-tip to twin lamella …

Experimental Investigation into the Long-Term Seismic Performance of Dry Storage Casks
… (DSCs). Four scaled specimens were designed to cover a wide range of commercially available DSCs with emphasis on aspect ratios, the radius over the height of the center of mass (r/hc.g.). The aspect ratios were: 0.39, 0.43, 0.56, and 0.62. Three 1/2.5 scale shake table experiments were conducted …

Alcohol use and misuse: exploring balance and change
… within the core category is the concept of the Tipping Point. Professional men recognise this as representing the significant point where the benefits of alcohol tip over into the costs. Learning is the process that continues throughout the lifespan, and achieving this balance is realised …

Modeling the Dynamic Response of Vertical Spent Nuclear Fuel Dry Storage Casks under Three-Dimensional Earthquake Wave Fields
… susceptible to sliding, rocking, and potential tip-over, leading to inter-cask collision during seismic events. Furthermore, soil-structure interaction (SSI) may significantly influence the dynamic response of such stiff structures founded on soft soil. While previous research studies have …

Solidification behavior and texture of laser-wire directed energy deposition of 316L austenitic stainless steel
… the melt pool stabilizing the austenite dendrite tip over the delta-ferrite dendrite tip as well as due to compositional variations between builds. The initial feedstock composition cannot accurately represent all the solidification mode variations of AM 316L indicating the need for the as-built …
