摘要:
ALICE (A Large Ion Collider Experiment) is the LHC (Large Hadron Collider) experiment devoted to investigating the strongly interacting matter created in nucleus-nucleus collisions at the LHC energies. The ALICE ITS, Inner Tracking System, consists of six cylindrical layers of silicon detectors with three different technologies; in the outward direction: two layers of pixel detectors, two layers each of drift, and strip detectors. The number of parameters to be determined in the spatial alignment of the 2198 sensor modules of the ITS is about 13,000. The target alignment precision is well below 10 mu m in some cases (pixels). The sources of alignment information include survey measurements, and the reconstructed tracks from cosmic rays and from proton-proton collisions. The main track-based alignment method uses the Millepede global approach. An iterative local method was developed and used as well. We present the results obtained for the ITS alignment using about 10(5) charged tracks from cosmic rays that have been collected during summer 2008, with the ALICE solenoidal magnet switched off.

摘要:
Fabrication of ZnO/graphene hybrid by homogeneous depositing a continuous and conformable ZnO layer on graphene remains a great challenge and highly desired. In this paper, well-defined flake-like ZnO/graphene hybrid was fabricated by a facile in situ hydrolysis-deposition route using zinc acetate and graphene oxide (GO) as starting materials and ammonia as precipitator and reductant. By rational control the hydrolysis and condensation of Zn precursor, ZnO nanocrystals are homogeneously anchored on graphene due to the strong interaction between ZnO and GO, which was simultaneously reduced to graphene. The photocatalytic activity of the photocatalyst was evaluated using Brilliant Red X-3B (X3B) dye as probe. It was found that the presence of GO enhanced the crystallization of ZnO, and the photocatalytic activity of ZnO/graphene hybrid increases first and then decreases with increasing the amount GO. The hybrid with 3 wt.% of GO shows the highest photocatalytic activity, which is 3 times higher than that of pure ZnO. (C) 2015 Elsevier B.V. All rights reserved.

摘要:
Nanorod vanadium sulfide wrapped by reduced graphene oxide (rGO) composite is synthesized by a facile solvothermal reaction. Nanorod vanadium sulfide is uniformly distributed on the surface of rGO nanosheets. As an anode for sodium ion batteries, the composite with 13 wt% rGO has 1203.8 and 781.4 mAh g-1 specific capacities for the first discharge and charge, respectively, with 64.9% of Coulombic efficiency, higher than that of pure vanadium sulfide submicrospheres. The sodiation/desodiation mechanism is investigated by cyclic voltanimetry, electrochemical impedance spectrum and discharging-charging measurement. The results show that the vanadium sulfide/rGO composite can convert to sodium sulfide + vanadium/rGO composite after the first cycle, and the rGO can inhibit the dissolution of polysulfide while metal vanadium increases electrode conductivity, resulting in the enhanced electrochemical performance.

摘要:
Two triazole-modified calix[4]arene diesters were synthesized via Huisgen 1,3-dipolar cycloaddition between azides esters and alkynylcalixarenes. Their structures had been deduced from (1)H NMR, element analysis and ESI-MS. Two-phase extraction experiments indicated that triazole-modified calix[4]arene diethylester 3a exhibited Cs(+) selectivity.

摘要:
Collective flow reflects the dynamical evolution in high-energy heavy ion collisions. In particular, the elliptic flow reflects early collision dynamics [1]. We present a systematic analysis of elliptic flow (v(2)) for identified particles measured in Au + Au and Cu + Cu collisions at root s(NN) = 200 GeV. Number of quark scaling is tested in the intermediate p(T) region and in the smaller system (Cu + Cu). The Cu + Cu collisions results are compared with those from ideal hydrodynamic model calculations.

摘要:
Data mining technology has emerged as a means for identifying patterns and trends from large quantities of data. Mining encompasses various algorithms such as clustering, classification, and association rule mining. In this paper we take advantage of the genetic algorithm (GA) designed specifically for discovering association rules. We propose a novel spatial mining algorithm, called ARMNGA(Association Rules Mining in Novel Genetic Algorithm), Compared to the algorithm in Reference[2], the ARMNGA algorithm avoids generating impossible candidates, and therefore is more efficient in terms of the execution time.

摘要:
Task scheduling is a NP-hard problem and is an integral part of parallel and distributed computing. It is more complicated especially under the grid computing environment. This paper combined with the advantages of genetic algorithm and simulated annealing, brings forward an improved genetic simulated annealing algorithm and applied to solve grid computing task scheduling problem. From the analysis and experiment result, it is concluded that this algorithm is superior to genetic algorithm and simulated annealing.

evolutionary algorithm;single-objective optimization;convergence and diversity
摘要:
As a key technique of computational intelligence, evolutionary computation has attracted increasing interest because of its advantages of self-adaptation, parallelism, and robustness in solving complex and nonlinear problems. Based on the review of recent development of evolutionary computation and the principle of free energy minimization of thermodynamics, a new dynamical evolutionary algorithm (DEA) for solving single-objective optimization problems is proposed. The algorithm is used to solve some global optimal problems and satisfactory numerical results are achieved. The results show that DEA is of potential to obtain global optimum or more accurate solutions than other evolutionary methods.
摘要:
Traditional region-based distribution model can no longer meet the requirements of logistics distribution practices in E-commerce. Rather, a new distribution strategy can solve the above mentioned contradiction effectively, in which different distribution regions integrate in transportation and each vehicle gets continuous replenishments along the distribution routine. Vehicle routing problem (VRP) is the key component for this strategy. This paper first states the assumptions of the strategy, and then builds the VRP model for a regional-integrated distribution system in E-commerce. According to the model's specific configuration, a heuristic algorithm is developed for gradual optimization, in which an initial viable distribution routing is given, It is then optimized by means of inserting route parts in descending order of their saving values. A numerical example is given to demonstrate the arithmetic operation at the end of this paper.

摘要:
In this paper, the present status of e-commerce major concerning undergraduate and graduate students in higher education of China and the U.S. was investigated. The comparative study showed that there were lots of differences in the setting up of e-commerce program or major between China and the U.S.. The main results are as follows: (1) the Chinese e-commerce education mainly concentrates on the establishment of e-commerce specialty, while the U.S. on the establishment of e-commerce courses or direction;(2) the Chinese e-commerce education emphasizes on the cultivation of undergraduate level, while the U.S. on the cultivation of graduate level;(3) the Chinese e-commerce education underlines the training of management talents, while the U.S. appreciates the training of application ones.

摘要:
Interoperability of heterogeneous systems on the Web will be admittedly achieved through an agreement between the underlying ontologies. However, the richer the ontology description language, the more complex the agreement process, and hence the more sophisticated the required tools. Among current ontology alignment paradigms, similarity-based approaches are both powerful and flexible enough for aligning ontologies expressed in languages like OWL. This paper definea a universal measure for comparing the entities of two ontologies that is based on a simple and homogeneous comparison principle: Similarity depends on the type of entity and involves all the features that make its definition (such as superclasses, properties, instances, etc.). One-to-many relationships and circularity in entity descriptions constitute the key difficulties in this context: These are dealt with through local matching of entity sets and iterative computation of recursively dependent similarities, respectively.
