We propose a three-step local polynomial procedure for a multivariate nonparametric regression in which the errors are autocorrelated. The proposed estimator uses all sample points to estimate m(x), the regression function evaluated at point x, but the contributions from all non-local points are...

In this paper we propose a modification of the local linear smoother to account for the autocorrelated errors in a nonparametric regression model with random-design. The proposed estimator has a closed-form expression and is simple to calculate. The asymptotic bias and variance of the proposed...

With the increasing penetration of renewable energy into energy market, it is urgent to solve the problem of fluctuations of renewable energy sources (RES). Energy storage technology is regarded as one method to cope with the unstable nature of RES. One of these technologies is compressed air...

As the penetration of renewable energy sources (RES) into energy market is becoming increasingly evident, it is urgent to deal with the problem of fluctuations of RES. Compressed Air Energy Storage (CAES), as one of energy storage technologies aiming at this problem, has excellent...

Titanium oxide films were prepared using an anodic oxidation method in sulfuric acid solution on the surface of Ti6Al4V alloy at room temperature. The surface energy was obtained by the measurement of contact angles and the calculation with Owens–Wendt–Kaeble's equation. Ti6Al4V with anodic...

A manganese oxide contained coating was prepared on biodegradable AZ31B magnesium alloy to control the degradation of AZ31B and improve its biocompatibility. Morphology, composition, and corrosion resistance of the coating were studied. The SEM observations showed that the coating was...

We study a firm's pricing/output strategy under threat of entry in a two-period game with asymmetric information, where the firm can reduce future cost through learning-by-doing. In contrast with previous literature, we show that a firm's incentive to reduce cost through higher production may...

We show an inverted-U relation between targetiveness (probability of being targeted) and firm size. However, this pattern describes stock offers and is more pronounced during hot markets characterized by higher stock valuations. For cash offers we find a negative and monotonic relation. These...

Although economists have analyzed earnings, unemployment, and labor force participation for those with bipolar illness, occupational choice has yet to be explored. Psychological and medical studies often suggest an association between bipolar illness and creative achievement, but they tend to...

Aiming at developing exhaust gas-driven automobile air conditioners, two types of systems varying in heat carriers were preliminarily designed. A new hydride pair LaNi4.61Mn0.26Al0.13/La0.6Y0.4Ni4.8Mn0.2 was developed working at 120–200°C/20–50°C/−10–0°C. P-C isotherms and reaction...
