Cloud computing provide an efficient big data processing platform for many small and medium scale enterprises, how to replicate and allocate data in clouds is a critical problem influencing cost consumption for small and medium scale enterprises. Cloud data management systems mainly serve two kinds of workloads, one is read-intensive analytical workloads (e.g. OLAP), the other is write-intensive transactional workloads (e.g. OLTP). It is essential to minimize data management costs like storage, communication bandwidth, update and power with guaranteeing the service level agreements. Toward two workloads, a cost-effective data replica placement approach for minimizing data management costs on cloud computing centers is proposed. The definition of different data management costs is identified first, then we construct the cost optimization model of the data replica placement problem. The paper proposes a hybrid genetic algorithm and a data support-based initialization method that addresses the problem. Experiments show that the approach result in significant reduction in total data management cost and the algorithm is with good performance. © IFIP International Federation for Information processing 2018.

This paper is concerned with sampled-data consensus of first-order delayed multi-agent systems with delayed-state-derivative feedback. First, the delay decomposition technique is used for obtaining the consensus protocol based on sampled-data. Then, the stability theory of linear systems and the algebra graph theory are employed to derive the necessary and sufficient conditions about the sampling period guaranteeing the achievement of consensus. Last, simulations are provided to demonstrate the effectiveness of the theoretical results.

A single electron transistor based on a silicon-on-insulator is successfully fabricated with electron-beam nano- lithography, inductively coupled plasma etching, thermal oxidation and other techniques. The unique design of the pattern inversion is used, and the pattern is transferred to be negative in the electron-beam lithography step. The oxidation process is used to form the silicon oxide tunneling barriers, and to further reduce the effective size of the quantum dot. Combinations of these methods offer advantages of good size controllability and accuracy, high reproducibility, low cost, large-area contacts, allowing batch fabrication of single electron transistors and good integration with a radio-frequency tank circuit. The fabricated single electron transistor with a quantum dot about 50nto in diameter is demonstrated to operate at temperatures up to 70K. The charging energy of the Coulomb island is about 12.5meV.

The project manager's role and influence on the project's overall outcome have fascinated many academicians, researchers, and practitioners. The project manager's leadership and human skills play a vital role in the project's outcome;therefore, it is imperative for these competencies to be identified, learned, and leadership styles to be adopted. This study aims to define the most relevant competencies to multidimensional project success and their interrelationship. The quantitative method was used by applying a survey to project managers and team members working in the public sector of Pakistan. The results suggest that a combination of emotional, managerial intelligence, and transformational leadership are stronger predictors of multidimensional public project success. This study has shown that management and leadership need to be integrated to achieve better results. Project managers need to combine soft and hard skills, leadership competencies, and management to engage with people and be effective in terms of processes, tasks, and objectives. © 1973-2011 IEEE.

Construction of LaFeO 3 loaded nitrogen-doped biochar for enhanced removal of tetracycline via ultrasonication-induced peroxymonosulfate activation process

Colloids and Surfaces A: Physicochemical and engineering Aspects 2025年 723卷

Antibiotics have caused serious environmental pollution due to their widespread presence in the environment and difficult degradation. Advanced oxidation processes (AOPs) based on activation of peroxymonosulfate (PMS) to remove recalcitrant emerging contaminants have shown great potential in water pollution control and remediation, thus constructing novel catalysts with functional and structural controllability has become a critical factor for success. In this study, nitrogen-doped biochar derived from the polypyrrole-functionalized collagen fiber was used as support for LaFeO 3 to prepare carbon-based bimetallic catalyst. Under assistance of ultrasonication (US), the catalytic performances of the N-BC@LaFeO 3 /PMS system for tetracycline (TC) degradation were investigated in detail and the effects of various environmental parameters were optimized in detail. The results showed that N-doped BC as an excellent carrier not only improved the aggregation of LaFeO 3 , but also demonstrated enhanced catalytic performances due to the synergistic effects between N-doped BC, bimetallic oxides and US. About 98 % of TC could be removed within 60 min reaction under the optimal conditions of catalyst dosage of 0.3 g/L, PMS concentration of 10 mmol/L, initial TC concentration of 10 mg/L, ultrasonic frequency of 45 kHz and natural pH. Moreover, the N-BC@LaFeO 3 /PMS/US system had the pH-independent performance with more than 95 % of TC removal within 20 min in a wide pH range of 3–10. Furthermore, N-BC@LaFeO 3 exhibited good salt resistance and superior recycling stability with degradation efficiency of TC above 94 % after 6 consecutive cycles. Additionally, the enhanced mechanisms of N-BC@LaFeO 3 /PMS/US system for TC elimination were explored and the possible degradation pathways of TC were proposed, which was ascribed to the synergistic effects of free radicals and non-free radicals. The results indicated that the ultrasound-assisted AOPs constructed by N-BC@LaFeO 3 /PMS had a

Supercapacitor Performance of Hollow Carbon Spheres by Direct Pyrolysis of Melamine-formaldehyde Resin Spheres

引用

Chemical Research in Chinese Universities 2013年第4期29卷 735-742页

R. China

The nitrogen and oxygen co-doped hollow carbon spheres（HCSs） were prepared via a simple pyrolysis of solid melamine-formaldhyde resin spheres. The carbonization temperature has an important influence on the specific surface area, pore-size distribution and heteroatom contents of HCSs. The synergistic effects of those physical and chemical properties on supercapacitor performance were systematically investigated. Among the HCSs obtained at different temperatures, HCSs-800（co-doped HCSs at 800℃） exhibits the best reversible specific capacitance in 2 mol/L H2SO4 electrolyte and meanwhile maintains a high-class capacitance retention capability. The nitrogen heteroatoms were confirmed to play a crucial role in improving capacitance in an acid medium. This kind of nitrogen doved HCSs is a potential candidate for an efficient electrode material for supercapacitors.
