The catalytic performances of common solid acids (ZSM-5(25), ZSM-5(36), NaY, H-mordenite, Zr3(PO4)4, SO42-/ZrO2, SO42-/TiO2, and TiO2) for the conversion of carbohydrates such as glucose to methyl levulinate in near-critical methanol were investigated to develop an environmentally benign...

How to sufficiently use the structure information behind the data is still a challenging issue. In this paper, a local linear–additive estimation and its relevant version are proposed to automatically capture the additive information for general multiple nonparametric regressions. Our method...

To reduce the curse of dimensionality arising from nonparametric estimation procedures for multiple nonparametric regression, in this paper we suggest a simulation-based two-stage estimation. We first introduce a simulation-based method to decompose the multiple nonparametric regression into two...

This paper empirically examines the determinants of director compensation and CEO compensation and investigates whether director compensation has an effect on CEO compensation. Based on 713 firms (or 2,852 firm-years) between 2007 and 2010, we find that CEO tenure is related to the ability of...

This paper presents experimental studies on a solar-assisted ground coupled heat pump (SAGCHP) system for space heating. The system was installed at the Hebei Academy of Sciences in Shijiazhuang (lat. N38°03′, long. E114°26′), China. Solar collectors are in series connection with the...

Recently, valorization of lignocellulosic biomass, the most abundantly available biomass raw material on the Earth, to biofuels and chemicals has attracted great attention worldwide for the purpose of reducing our overwhelming reliance on the non-renewable petroleum resources. γ-Valerolactone...

Nowadays, microalgae received wide attention due to several advantages for biochemicals and renewable/sustainable biofuels production. Moreover, the utilization of microalgae as robust cellular species for biological nutrient removal from industrial and domestic wastewater streams has been of...

This study uses a case study method to examine the spin-offs of Asus and Yulon. Both companies show negative cumulated abnormal returns after spin-off announcements and then return to the anchoring price as at the announcement day. The results are in contrast to the findings of Veld et al....

In this paper, the only assumptions on the distribution of data are those concerning first two moments. Our purpose is to estimate the parameter of interest in the presence of nuisance parameter under these weak assumptions on the distribution. We define a quasi-least favorable curve and...
