Advanced Engineering Materials, EarlyView.Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...

, 1997 Let f be a polinomial with coefficients in a finite field F. Let $Ψ: F \to C^{\ast}$ be a non-trivial additive character. In this paper we give bounds for the exponential sums $\sum_{x\in F^n} Ψ(Tr_{F/F_p} (f(x)))$ in some cases where the highest degree form of f defines a singular projective hypersurface X (e.g.

Exponential Smoothing Model Selection for Forecasting [PDF]
Applications of exponential smoothing to forecast time series usually rely on three basic methods: simple exponential smoothing, trend corrected exponential smoothing and a seasonal variation thereof. A common approach to select the method appropriate to

Uniformly exponential growth and mapping class groups of surfaces [PDF]
, 2007 We show that the mapping class group (as well as closely related groups) of an orientable surface with finitely generated fundamental group has uniformly exponential growth.

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias
Advanced Engineering Materials, EarlyView.Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

Invertibility Conditions for Exponential Smoothing Models [PDF]
In this article we discuss invertibility conditions for some state space models, including the models that underly simple exponential smoothing, Holt's linear method, Holt-Winters' additive method and damped trend versions of Holt's and Holt-Winters ...

Advanced Engineering Materials, EarlyView.Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Exponential Sums and Lattice Points [PDF]
Proceedings of the London Mathematical Society, 1990 The area A inside a simple closed curve C can be estimated graphically by drawing a square lattice of sides 1/M. The number of lattice points inside C is approximately \(AM^ 2\). If C has continuous nonzero radius of curvature, the number of lattice points is accurate to order of magnitude at most \(M^{\alpha}\) for any \(\alpha >2/3\). We show that if
