Excess sludge from wastewater treatment plants (WWTPs), the hotpot of antibiotic resistance genes (ARGs), is widely deposed by composting due to abundant nutrients. However, few studies applied sludge compost products (SCP) as soil amendments because of ARGs and heavy metals in sludge. To...

Project scheduling is one of the core elements of project management, which is essential for engineering-to-order manufacturing companies to improve productivity, reduce costs and shorten project finish time. This paper explores the multi-mode project scheduling problem under resource and finish...

The article models the borrowing producers in a production supply chain with insurer green finance. The borrowing firms’ transacting carbon allowances (CA) under the cap-and-trade mechanism affect the insurer’s loan rate-setting and guaranteed rate-setting decisions. One result shows that a...

We present an approach to automate the bidding and budgeting of multi-unit digital advertising campaigns. Such campaigns typically involve groups of ad-units that span multiple user segments, ad-delivery channels and media that together are meant to deliver on the advertiser's goals. Our model...

Design of the cheap and high efficiency catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is imperative for rechargeable Zn-batteries (r-ZABs). Herein, the cobalt nanoparticles encapsulated in iron and nitrogen co-doped urchin-like porous carbons (Co@Fe-Nx/C) as a...

A traveling-wave flow field is proposed and investigated for the performance improvement effect of proton exchange membrane fuel cell (PEMFC). This study analyzes the influence of multiple structural parameters of traveling-wave length, wave height, wave number, and wave spacing on the flow law,...

Mg alloys are ultralight but their structural applications are often limited by their poor wear and corrosion resistance. The research aimed to address the problem by laser-cladding. Cladding with SiC powder onto surface of AZ91D was carried out using Nd:YAG laser. The laser-clad surface was...

Lead–acid batteries used in hybrid solar–wind power generation systems operate under very specific conditions, and it is often very difficult to predict when the energy will be extracted from or supplied to the battery. Owing to the highly variable working conditions, no battery model has...

Wind power potentials of the Pearl River Delta (PRD) region have been statistically analyzed based on the hourly measured wind speed data in four islands. The hourly and monthly wind speed and wind power density are assessed to have remarkable variations, and the Weibull distribution function...

We give an example of quasiderivatives constructed by random time change, Girsanov’s Theorem and Levy’s Theorem. As an application, we investigate the smoothness and estimate the derivatives up to second order for the probabilistic solution to the Dirichlet problem for the linear degenerate...
