Wire arc additive manufacturing achieves high efficiency and low costs by using a melting wire for directional depositions. Thermal analyses the finite element method have been applied to predict residual stress deformation of fabricated parts. For Ni-based alloy production, predicting solidification microstructure evolution with segregation is needed in order design precise heat treatment proc...

I study a model of electoral competition where two parties that care about both the spoils office and policy compete by announcing platforms. Parties are characterized their valence on one hand platforms other. Unlike in extant literature, assume complements (instead substitutes) from voter's perspective. generally characterize equilibrium show such framework increasing or parties' level(s) lea...

Localization may survive in periodically driven (Floquet) quantum systems, but is generally unstable for aperiodic drives. In this Letter, we identify a hidden conservation law originating from chiral symmetry disordered spin-$\frac{1}{2}$ XX chain. This protects indefinitely long-lived localization general---even aperiodic---drives. Therefore, rather counterintuitively, adding further potentia...

In this study fuzzy arithmetic is presented as a tool to tackle the prediction of the amount of barium, strontium and calcium sulfates scales in oilfield operations. Since the shape of fuzzy numbers’ membership functions is a spread representative of the whole possible values for a special model parameter, fuzzy numbers are able to consider the uncertainties in parameter determinations and thus...

Since the dawn of history (and certainly before) people have bickered, even battled, over the fair distribution of resources— for example, the division of estates, disputed territories and the spoils of war. Such dilemmas have for the most part been resolved unilaterally, by kings (Solomon and the baby), judges or simple force. Few truly logical solutions evolved. In the past 50 years, however,...

We are interested in how individuals and communities develop opinions as they design and use new mobile, public-sphere technologies. We situate our work among new considerations of ethnography, mobile technologies and rhetoric and describe the design and pilot installation of a new technology called TexTales designed to support mobile public discourse. Mobility in the end may supply the means b...
