A State Space Framework for Automatic Forecasting Using Exponential Smoothing Methods. [PDF]
We provide a new approach to automatic business forecasting based on an extended range of exponential smoothing methods. Each method in our taxonomy of exponential smoothing methods can be shown to be equivalent to the forecasts obtained from a state ...

Results in EngineeringThe adoption of environmentally safer oils, such as TDAE (Treated Distillate Aromatic Extract), in rubbers has traditionally been approached with caution due to concerns over potential deterioration in filler dispersion and adverse impacts on mechanical ...

Advanced Functional Materials, EarlyView.A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Validity and precision of estimates in the classical newsvendor model with exponential and rayleigh demand [PDF]
In this paper we consider the classical newsvendor model with profit maximization. When demand is fully observed in each period and follows either the Rayleigh or the exponential distribution, appropriate estimators for the optimal order quantity and the

Ain Shams Engineering JournalThis work investigates an extended nonlinear Schrödinger equation that incorporates both even- and odd-order higher-dispersion and nonlinear terms. Such an extended model is physically important because it captures realistic propagation dynamics of ...

Advanced Functional Materials, EarlyView.Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Equilibrium Price Dispersion in a Matching Model with Divisible Money [PDF]
The main purpose of this paper is to show that, for any given parameter values, an equilibrium with dispersed prices (two-price equilibrium) exists in a simple matching model with divisible money presented by Green and Zhou (1998).We also show that our ...

A Note on NPML Estimation for Exponential Family Regression Models with Unspecified Dispersion Parameter [PDF]
Austrian Journal of Statistics, 2006 Nonparametric maximum likelihood (NPML) estimation for exponential families with unspecified dispersion parameter ? suffers from computational instability, which can lead to highly fluctuating EM trajectories and suboptimal solutions, in particular when ? is allowed to vary over mixture components. In this paper, a damped version of the EM algorithm is

Advanced Functional Materials, EarlyView.Sodium alginate regulates interfacial ion transport and retention in electrolyte‐gated synaptic transistors. The carboxylate‐rich polymeric network forms a dynamic interfacial ion‐diffusion barrier that facilitates ion injection during programming while suppressing ion back‐diffusion, thereby stabilizing the electrochemically doped channel state.

Robust exponential smoothing of multivariate time series. [PDF]
Multivariate time series may contain outliers of different types. In presence of such outliers, applying standard multivariate time series techniques becomes unreliable. A robust version of multivariate exponential smoothing is proposed.
