摘要：
The catalytic steam gasification of municipal solid waste (MSW) for hydrogen-rich fuel gas production was experimentally investigated in a combined fixed bed reactor using the newly developed tri-metallic catalyst. The results indicated that the supported tri-metallic catalyst had a high activity of cracking tar and hydrocarbons, upgrading the gas quality, as well as yielding a high hydrogen production in catalytic steam gasification of municipal solid waste. A series of experiments have been performed to explore the effects of catalyst presence, catalyst to MSW mass ratio (C/M), catalytic temperature, steam to MSW ratio (S/M) and MSW particle size on the composition and yield of gasification gases. The experiments demonstrated that temperature was the most important factor in this process; higher temperature contributed to more hydrogen production and gas yield. Varying catalyst to MSW mass ratio (C/M) demonstrated complex effects on gas yield and composition of MSW gasification and an optimal value of 0.5 was found in the present study. Comparing with MSW catalytic gasification, the introduction of steam improved gas quality and yield, the optimal value of S/M was found to be 1.33 under the present operating condition. It was also shown that a smaller particle size was more favorable for gas quality and yield. (C) 2012 Elsevier Ltd. All rights reserved.

摘要：
To be able to predict tribological properties of new lubricant additives as well as clarify lubricating mechanisms, one needs to study the relationship between structures of lubricant additives and their lubricating properties. With a focus on estimating antiwear properties of some heterocyclic additives, we use the quantitative structure tribo-ability relationship (QSTR) model to predict tribological data, which introduces the idea of computer-aided design into tribology. This is combined with back propagation neural network (BPNN), a machine-learning method that offers simplicity and robustness. This study determined the feasibility and predictability of developing the BPNN QSTR model to estimate lubricant additive antiwear properties. For 36 additives, 90 structural descriptors, such as octanol-water partition coefficient, quantum indices, 2D topological indices, and 3D Jurs descriptors, were included as BPNN inputs. Antiwear parameters include wear-scar diameters under three loads. Leave-one-out cross-validation was performed to evaluate accuracy and robustness of this BPNN QSTR model. We also evaluate the descriptor sensitivities, from which we can determine the effects of each descriptor and clarify wearing mechanisms. Given a positive assessment, this method warrants further development and validated integration with other tribological properties. Crown Copyright (C) 2012 Published by Elsevier B.V.

摘要：
A social network is a social structure made up of a set of social actors (such as individuals or organizations) and a set of the dyadic ties between these actors. By contrast, for the fixed time duration the size of digital video would be much bigger than that of digital sound. Consequently, providers of social network services can offer real-time chatting among users which could offer satisfactory experiences for users. As one of the most popular content-based social network services (SNS), chatting service plays an important role in current big data era. Also average data packets' transmission via networks is another significant traffic. So how to offer satisfactory Quality of Service (QoS) for users is the key problem which will be solved for SNS provider. For real time communication among users, end-to-end time delay seems to be critical in user's experience. Therefore modeling and evaluating social network systems is an important and urgent issue which offers quantitative basis of SNS with high quality for users. For social network system, the scalability and robust are important for both service provider and users under the circumstance of a large number of users. On the basis of performance evaluation of social network system of one user case, we construct the SPN model and conduct numerical analysis to discover and report the performance with the addition of users. By taking hybrid traffic containing voice and data into account, this paper constructed a Stochastic Petri Net (SPN) model for data and ON/OFF voice traffic for social network system. Then, average time delay of the system was analyzed and model-based simulation is conducted with Stochastic Petri Net Package (SPNP) 6.0. Furthermore, for different parameters of burst rate, idle rate, number of data packets, traffic load and buffer size, variation trends on average time delay are derived thereby. On the basis of the work in this paper, further research on heterogeneous objects of social network systems can be carried on. (C) 2016 Elsevier B.V. All rights reserved.

摘要：
Urethane-based polymers are very biocompatible in many biomedical applications. This study reports the synthesis of new low viscosity urethane dimethacrylates and evaluation of the formed composites. New urethane dimethacrylates were synthesized and formulated to form the composites. Compressive strength was used as a primary tool to evaluate the mechanical property. Water sorption, solubility, degree of conversion, flexural strengths and shrinkage were also investigated. It was found that liquid urethane dimethacrylates could be synthesized by derivatizing isocyanates with asymmetrical methacrylates. By eliminating diluent triethylene glycol dimethacrylate, the new urethane dimethacrylate-composed composites showed significantly higher modulus, lower water sorption, lower solubility and lower shrinkage, as compared to commercial BisGMA- and UDMA-based ones.

摘要：
This paper presents an electrocardiographic signal classification method. This method first uses a revised locally linear embedding (LLE) algorithm to perform dimension reduction to the Electrocardiography (ECG) data. This manifold distance measurement-based LLE was proposed to solve the defect of conventional LLE that, due to the use of Euclidean distance, it could not properly measure the distance between high-dimensional samples. Using this revised LLE algorithm for the dimension reduction of data, more original data information could be retained, and the features of high-dimensional ECG data could be more effectively extracted, thereby improving the classification accuracy. The method then adopts kernel-based fuzzy C-means clustering algorithm to perform ECG signal classification. Classification tests on four common types of ECG signals-from the MIT-BIN database showed that the proposed method reached an overall accuracy of 99%.

Bionics algorithm - Generalized constitutive law - Immunized evolutionary programming - Model identification
摘要：
From the generalized constitutive law of geo-material elastic-plastic model, the problem of model identification among one model type is transformed to a problem of parameter identification. So, using the new bionics algoritlun-Immune Evolutionary Programming (IEP) proposed by author recently, the elastic-plastic model identification among one model type is studied, and a new model identification method is proposed. At last, this method is verified by a numerical example. The results show that, this method can get the suitable geo-material model when only displacements are known.

摘要：
A selective and sensitive spectrophotometric method has been developed for determining the total amount of vanadium in carbonaceous shales (stone coal ores). The method is based on the reaction of vanadium(V) with the chromophore reagent 2‐(5‐bromo‐2‐pyridylazo)‐5‐diethylaminophenol (5‐Br‐PADAP) in the presence of hydrogen peroxide. In a 0.072 mol l−1 sulfuric acid medium, 5‐Br‐PADAP reacts with vanadium(V) to form a red‐violet complex with a maximum absorption peak at 596 nm with an apparent molar absorption coefficient of the complex of 8.45 × 104 l mol−1 cm−1. Beer's law was obeyed in the range 0–25 μg vanadium in 25 ml of solution, with a correlation coefficient of 0.9995. Interferences due to various non‐target ions were also investigated and high quantities of other common inorganic ions were tolerable. The method involved the dissolution of the ore sample by Na2O2 fusion, followed by filtering of the alkali solution after which Fe(III), Cu(II), Ni(II) and Co(II) etc. were effectively separated from the solution by precipitation in a NaOH solution. Selectivity was increased with the use of EDTA as a masking agent. The vanadium in ore samples was determined with a relative deviation (RSD) between 0.20 and 0.76%, and has been successfully applied to the determination of vanadium‐bearing stone coal ores. The results indicated that the accuracy of 5‐Br‐PADAP spectrophotometry is comparable with the ICP‐AES method. The characteristics of the method, i.e., simplicity, selectivity, sensitivity and rapid calibration, make it specially suitable for routine analysis. Une méthode spectrophotométrique sélective et sensible a été développée pour déterminer la concentration totale de vanadium dans les minerais rocheux de charbon. La méthode est basée sur la réaction du vanadium (V) avec l'agent coloré 2‐(5‐bromo‐2‐pyridylazo)‐5‐diethylaminophenol (5‐Br‐PADAP) en présence de peroxyde d'hydrogéne. Dans une solution d'acide sulfurique, le 5‐Br‐PADAP réagit avec le vanadium pour former un complexe rouge violacé qui a son pic maximum d'absorption à 596 nm et un coefficient d'absorption molaire apparent de 8.45 × 104 l mol−1 cm−1. La loi de Beer est vérifiée entre 0 et 25 μg de vanadium dans 25 ml de solution, avec un coefficient de corrélation de 0.9995. Les interférences dues à différents ions parasites ont aussi été recherchées et d'importantes quantités des autres ions inorganiques communément trouvés se sont révélées tolérables. La méthode comprenait la mise en solution de l'échantillon de minerai par fusion avec Na2O2, suivie d'une filtration de la solution alcaline ensuite de quoi Fe(III), Cu(II), Ni(II) et Co(II) etc. ont étééliminés de la solution par précipitation dans une solution de NaOH. La sélectivité a été augmentée par l'utilisation de EDTA comme agent masquant. Le vanadium dans les minerais a été déterminé avec une déviation relative standard (RSD) comprise entre 0.20 et 0.76% et la méthode a été appliquée avec succés à la détermination du vanadium dans des minerais rocheux de charbon. Les résultats montrent que la précision de la spectrophotométrie de 5‐Br‐PADAP est comparable à celle obtenue avec l'ICP‐AES. Les caractéristiques de cette méthode, à savoir sa simplicité, sa sélectivité, sa sensibilité et sa calibration rapide en font une méthode particuliérement adaptée aux analyses de routine.

摘要：
The effect of impact damage is tightly relevant to structure survivability, experimental study on impact damage of structures is one of the most important measures that supply data for the evaluation of structure survivability. In this paper, some experimental studies on the damage of typical aircraft structure subjected to discrete low velocity impact are performed. Plexiglas (MDYB-3) is a typical material usually used in aeronautical engineering structures such as aircraft canopy windshield. For this aeronautical structure, preliminary studies on the relations among impact energy, impact damage and remaining strength of structure subjected to impact loading are conducted experimentally. In the impact experiments, free-fall dropping dart device with four different kinds of dart heads are used for the plate specimen of MDYB-3, the impact damages produced by different dart heads are figured by damage depth and damage area. Remaining tensile strength and fatigue life tests are implemented and the relationship between remaining strength of structures and impact damage is studied and discussed. Results obtained from these experiments are basic to further analysis and evaluation on structure survivability.
摘要：
At the present time, the mechanics of seepage in fracture-cavity carbonate reservoir is not very clear. Fracture-cavity carbonate reservoir was simplified as regular fracture-cavity net model and rules of seepage in it were studied by numerical simulation based on Navier-Stokes equation (N-S equation). Results showed that flux exponentially increased along with the increase of fracture width but flux and diameter of cavity had linear relationship; the seepage in fracture-cavity also obeyed the Darcy's law, but the permeability was bigger than the fracture model's, which represented different performance of flow; fracture width had more impact to seepage than diameter of cavity.

摘要：
The ability to detect a new fault class can be a useful feature for an intelligent fault classification and diagnosis system. In this paper, we adopt two novelty detection methods, the support vector data description (SVDD) and the Parzen density estimation, to represent known fault class samples, and to detect new fault class samples. The experiments on real multi-class bearing fault data show that the SVDD can give both high identification rates for the prescribed 'unknown' fault samples and the known fault samples, which shows an advantage over the Parzen density estimation method in our experiments, via choosing the appropriate SVDD algorithm parameters.
