Compared to traditional distributed computing like grid system, it is non-trivial to optimize cloud task’s execution performance due to its more constraints like user payment budget and divisible resource demand. In this paper, we analyze in-depth our proposed optimal algorithm minimizing task execution length with divisible resources and payment budget: 1) We derive the upper bound of cloud …
The advertising budget allocation problem for financial service is dealt with based on statistical learning and evolutionary computation in this paper. Taking the carry-over effects of the advertising into account, the least squares support vector machine regression (LS-SVMR) is used to construct the response model. A comparison between the proposed response model and traditional regressionmeth…
Understanding nanostructure growth faces issues of limited data, lack of physical knowledge, and large process uncertainties. These issues result in modeling difficulty because a large pool of candidate models almost fit the data equally well. Through the Integrated Nanomanufacturing and Nanoinformatics (INN) strategy, we derive the process models from physical and statistical domains, respect…
Abstract The bottom-up fabrication of nanostructures can simultaneously face large uncertainties from experimental runs (R), physical understanding (P), and measurement (M). No systematic strategy has been reported to manage these three types of uncertainties, abbreviated as RPM, concurrently to achieve better understanding of nano fabrication processes. Previously, we developed cross-domain m…
Abstract. A hybrid supercapacitor, which was assembled with an H-insertion negative carbon electrode and an electrochemical double-layer positive electrode, was studied and its structure was optimized. The electrochemical performance of the individual electrode with different negative to positive electrode mass ratios was investigated. It has been demonstrated that the performance of the hy…
Shy-sensitive children are likely to develop adjustment problems in today’s urban China as the country has evolved into an increasingly competitive, marketoriented society. The main purpose of this one-year longitudinal study was to examine the moderating effects of academic achievement on relations between shynesssensitivity and later internalizing problems in Chinese children. A sample of …
Abstract. Arsenate is one of the main contaminants threatening water supplies all over the world. Layered double hydroxides (LDHs) have large surface areas and high anion exchange capacities, so they may be used to develop rapid and cost-effective methods for scavenging As from contaminated water. In order to enhance arsenate adsorption of layered double hydroxides, it is essential to have …
Abstract. Ethylene-propylene-diene terpolymer (EPDM)/organoclay nanocomposites were prepared by melt extrusion in a twin-screw extruder. The organoclay was characterized by XRD and TGA. As observed by transmission electron microscopy (TEM), the organoclay particles were exfoliated in EPDM. The tensile strength of the nanocomposites increased to 12.3 MPa at the same 3.0 phr amounts of fillers, …
Abstract. Layered double hydroxides (LDHs) have high surface area and high anion exchange capacity, so they have been proposed to be an effective scavenger for contaminants. In this study, the adsorption of 2,4-dichlorophenoxyacetate (2,4-D) on Mg/Al–NO3 LDHs with varying layer charge density was investigated with particular attention on the effect of the orientation of the interlayer nitrat…
