Microstructures and properties of Al_2O_3 dispersion-strengthened copper alloys prepared through different methods

Al_2O_3 dispersion copper alloy powder was prepared by internal oxidation, and three consolidation methods—high-velocity compaction (HVC), hot pressing (HP), and hot extrusion (HE)—were used to prepare Al_2O_3 dispersion-strengthened copper (Cu–Al_2O_3) alloys. The microstructures and properties of these alloys were investigated and compared. The results show that the alloys prepared by the HP and HE methods exhibited the coarsest and finest grain sizes, respectively. The alloy prepared by the HVC method exhibited the lowest relative density (98.3% vs. 99.5% for HP and 100% for HE), which resulted in the lowest electrical conductivity (81% IACS vs. 86% IACS for HP and 87% IACS for HE). However, this alloy also exhibited the highest hardness (77 HRB vs. 69 HRB for HP and 70 HRB for HE), the highest compressive strength (443 MPa vs. 386 MPa for HP and 378 MPa for HE), and the best hardness retention among the investigated alloys. The results illustrate that the alloy prepared by the HVC method exhibits high softening temperature and good mechanical properties at high temperatures, which imply long service life when used as spot-welding electrodes.
Self-suspended Pure Polydiacetylene Nanoparticles with Selective Response to Lysine and Arginine

We demonstrate a very convenient access to self-suspended pure poly(10,12-pentacosadiynoic acid) (PDA) nanoparticles (NPs) simply by adding the ethanol solution of diacetylene monomer to water, followed by UV irradiation. The as-obtained PDA NPs are of high purity because no any initiator, catalyst or stabilizer was used during the whole process. The stabilizer-free PDA NPs are stable in the aqueous suspension. Due to the high purity and stability, the PDA NPs can respond sensitively and selectively to lysine and arginine among 18 kinds of water soluble natural amino acids; without the competitive interaction from the stabilizer, the sensitivity was enhanced.
Multiattribute Decision Making Method Based on Intuitionistic Linguistic Aggregation Operator

In this paper, some new operational laws for intuitionistic linguistic numbers are defined via Archimedean t-norm and s-norm. The prominent feature of these operations is that these operations are closed. Some main properties of these operations, like commutativity, associativity and distribution law, are investigated. Based on these operational laws, intuitionistic linguistic weighted arithmetic averaging operator is given to aggregate intuitionistic linguistic information. Furthermore, in order to reduce uncertain information of intuitionistic linguistic number, hesitancy degree is divided into degrees of membership and non-membership in proportions, and new expected function and score function are built and used to rank intuitionistic linguistic numbers. Finally, an approach is proposed to solve multiattribute decision making problems in which attribute weights are real numbers and attribute values are intuitionistic linguistic numbers, and a real example is provided to show the effectiveness and applicability of the new method.
New Results on Multiple Solutions for Intuitionistic Fuzzy Differential Equations

The first-order fuzzy differential equations with intuitionistic fuzzy initial valued problem is studied. Firstly, with the help of (a, β)-cut set, the distance metric and the Hukuhara difference between intuitionistic fuzzy numbers are defined, and on this basis the concept of differentiability for the intuitionistic fuzzy number-valued functions is defined and a corresponding theorem is derived. Then, according to the selection of derivative the first order intuitionistic fuzzy differential equations is interpreted. Finally, an example of first-order linear intuitionistic fuzzy differential equations is solved, and the results show that there are four different solutions.

Frequency domain based super-resolution method for mixed-resolution multi-view images

Super-resolution (SR) techniques, which are based on single or multi-frame low-resolution (LR) images, have been extensively investigated in the last two decades. Mixed-resolution multiview video format plays an important role in three-dimensional television (3DTV) coding scheme. Previous work considers multiview or multi-camera images and videos at the same resolution, which performs well under the planar model without or with little projection error among the videos captured by different cameras. In recent years, several researchers have discussed the SR problem in mixed-resolution multi-view video format, where the superresolved image is created using the up-sampled version of the LR image and the high frequency components extracted from the warped image in the adjacent high-resolution (HR) views. Unfortunately, the output HR images suffer from artifacts caused by depth error. To obtain the detailed texture and edge information from the HR image as much as possible, while preserving the structure of the LR image, a novel SR reconstruction algorithm is proposed. The algorithm is composed of three components: the structure term, the detail information term, and the regularization term. The first term preserves the structure similarity of the LR image; the second term extracts detailed information from the adjacent HR image; and the last term ensures the uniqueness of the solution. Experimental results show the effectiveness and robustness of the proposed algorithm, which achieves high performance both subjectively and objectively.
Full aperture imaging algorithm for highly squinted TOPS SAR

Aiming at solving the azimuth signal aliasing problem in the Doppler domain, the azimuth time aliasing problem after range cell migration correction (RCMC) and the severe range and the azimuth coupling problem in both the phase and envelope for highly squinted terrain observation by progressive scans (TOPS) synthetic aperture radar (SAR), a novel full aperture imaging algorithm is presented. An unaliased two-dimensional (2-D) spectrum is first obtained by the azimuth preprocessing; the modified range migration algorithm (RMA) is then used to complete RCMC; and finally the azimuth signal is focused in the Doppler domain by spectral analysis (SPECAN) and deramping. Simulations and real data processing results validate the effectiveness of the proposed algorithm.
A fully automated framework for helicopter rotor blades design and analysis including aerodynamics, structure, and manufacturing

This study describes an integrated framework in which basic aerospace engineering aspects (performance, aerodynamics, and structure) and practical aspects (configuration visualization and manufacturing) are coupled and considered in one fully automated design optimization of rotor blades. A number of codes are developed to robustly perform estimation of helicopter configuration from sizing, performance analysis, trim analysis, to rotor blades configuration representation. These codes are then integrated with a two-dimensional airfoil analysis tool to fully design rotor blades configuration including rotor planform and airfoil shape for optimal aerodynamics in both hover and forward flights. A modular structure design methodology is developed for realistic composite rotor blades with a sophisticated cross-sectional geometry. A D-spar cross-sectional structure is chosen as a baseline. The framework is able to analyze all realistic inner configurations including thicknesses of D-spar, skin, web, number and ply angles of layers of each composite part, and materials. A number of codes and commercial software (ANSYS, Gridgen, VABS, PreVABS, etc.) are implemented to automate the structural analysis from aerodynamic data processing to sectional properties and stress analysis. An integrated model for manufacturing cost estimation of composite rotor blades developed at the Aerodynamic Analysis and Design Laboratory (AADL), Aerospace Information Engineering Department, Konkuk University is integrated into the framework to provide a rapid and dynamic feedback to configuration design. The integration of three modules has constructed a framework where the size of a helicopter, aerodynamic performance analysis, structure analysis, and manufacturing cost estimation could be quickly investigated. All aspects of a rotor blade including planform, airfoil shape, and inner structure are considered in a multidisciplinary design optimization without an exception of critical configuration.
Design and implementation of rigid-flexible coupling for a half-flexible single jack nozzle

The aerodynamic design of a rigid-flexible coupling profile is the decisive factor for the flow-field quality of a supersonic free jet wind tunnel nozzle, and its mechanic dynamic features are the key for engineering implementation of continuous Mach number regulations. To fulfill the requirements of a free jet inlet/engine compatibility test within a wide simulation envelop, both uniform flow-fields of continuous acceleration and deceleration are necessary. In this paper, the aerodynamic design methods of an expansion wall and machinery implementation plan for the halfflexible single jack nozzle were researched. The profile control in nozzle flexible plate design was studied with a rigid-flexible coupling method. Design and calculations were performed with the help of numerical simulation. The technique of axial free stretching of the flexible plate was used to improve the matching performance between the designed elasticity profile and the theoretical one, and the rigid-flexible coupling structure was calibrated by wind tunnel tests. Results indicate that the flexible plate aerodynamic design method used here is effective and feasible. Via rigidflexible coupling design, the flexible plate agrees with the rigid body very well, and continuous Mach number changes can be achieved during the tests. The nozzle’s exit flow-field uniformity meets the requirements of China Military Standard (GJB).
Drift Control Technology Using Wire-Suspension for the Airgun Source Platform in Qilian Mountain

There are several key issues in dynamic monitoring of subsurface structures,such as signal-to-noise ratio (SNR),repeatability of seismic sources and accurate measurement of velocity. Using a large volume airgun source,we constructed a high-performance active system which mainly consists of airgun excitation and signal reception. In order to reduce the platform drift from the shot position,we put forward the platform drift control technique. Experimental results show that the technique can effectively solve the problem of platform drift from the set position under fluid impact after airgun excitation. The results of this study can be a reference for repeated airgun source detection at certain excitation sites.
Research on Large Volume Airgun Source Signal Reception in Hutubi,Xinjiang Using Seismic Network Data

We used data from the Xinjiang Digital Seismic Network and PSD (Power Spectral Density) method to perform noise level assessment for six stations. We calculated the median of the power spectral density to evaluate the noise level of different stations. After the comparison of the power spectral density of different stations and the airgun signal recognition,we found that noise level of stations with recognizable airgun source signals is lower than that of stations without recognizable signals. The largest difference of the power spectral density is 40dB,and the smallest is 15dB. Finally,we found that the failure to recognize the signal of airgun sources at some stations is due to the noise level.
Study on the Deconvolution Method and Processing Flow of Airgun Source Data

With its high repeatability,the airgun source has been used to monitor the temporal variations of subsurface structures. However,under different working conditions,there will be subtle differences in the airgun source signals. To some extent,deconvolution can eliminate changes of the recorded signals due to source variations. Generally speaking,in order to remove the airgun source wavelet signal and obtain the Green’s functions between the airgun source and stations,we need to select an appropriate method to perform the deconvolution process for seismic waveform data. Frequency domain water level deconvolution and time domain iterative deconvolution are two kinds of deconvolution methods widely used in the field of receiver functions,etc. We use the Binchuan (in Yunnan Province,China) airgun data as an example to compare the performance of these two deconvolution methods in airgun source data processing. The results indicate that frequency domain water level deconvolution is better in terms of computational efficiency; time domain iterative deconvolution is better in terms of the signal-to-noise ratio (SNR),and the initial motion of P-wave is also clearer. We further discuss the sequence issue of deconvolution and stack for multiple-shot airgun data processing. Finally,we propose a general processing flow for the airgun source data to extract the Green’s functions between the airgun source and stations.

Development and Implementation of a Technique for Norms-Adaptable Agents in Open Multi-Agent Communities

In open normative multi-agent communities, an agent is not usually and explicitly given the norms of the host agents. Thus, when it is not able to adapt the communities's norms, it is totally deprived of accessing resources and services from the host. Such circumstance severely affects its performance resulting in failure to achieve its goal. Consequently, this study attempts to overcome this deficiency by proposing a technique that enables an agent to detect the host's potential norms via self-enforcement and update its norms even in the absence of sanctions from a third-party. The authors called this technique as the potential norms detection technique (PNDT). The PNDT consists of five components: Agent's belief base; observation process; potential norms mining algorithm (PNMA); verification process; and updating process. The authors demonstrate the operation of the PNMA algorithm by testing it on a typical scenario and analyzing the results on several perspectives. The tests' results show that the PNDT performs satisfactorily albeit the success rate depends on the environment variables settings.

竞争风险型数据统计分析理论研究进展

在医学随访研究中,受试者在观察期间常常由于出现其他结局事件而阻碍目标结局事件的发生或改变目标结局事件发生的概率。例如,在人群原因别死亡率的研究中目标结局事件为肿瘤相关死亡,但随访过程中常出现心脑血管相关死亡而阻止了肿瘤相关死亡事件的发生,即竞争风险(competing risk)。在此理论框架下可能出现:(1)目标结局事件(event of interest);(2)竞争事件(competing event); (3)删失事件(cersored)。竞争风险在医学研究中十分普遍,其最早可以追溯到1760年伯努利接种“疫苗”根除天花对人群死亡率的影响。
天津市城镇职工医疗保险癫痫患者医疗资源使用与直接医疗负担分析

癫痫是一种严重危害人群健康的常见病、多发病,不仅给患者带来极大的痛苦,也增加了患者家庭、个人和社会的疾病负担。据世界卫生组织统计,全球大约有五千万癫痫患者,其中中国患者人数约占患者总人数的1/6。由于具有发作频繁、治疗周期长等特点,癫痫给患者、社会都带来了巨大的医疗负担。美国一项基于1999~2004年间的随访研究揭示了癫痫病每年对美国造成的经济影响:按照210万癫痫患者估计,其每年的医疗总费用约95亿美元。2010年,癫痫对韩国造成的社会经济总负担约5360亿韩元(5.03亿美元),占韩国当年医疗总费用的0.64%。目前中国对癫痫的医疗负担研究较少,国内已有的两项研究仅仅是基于一家医院或少量患者的回顾性资料进行分析,其数据结果的全面性、准确性和代表性有限。

目的:评估地面反射型踝足矫形器(floor reaction ankle foot orthosis,FRAFO)对学龄期痉挛脑性瘫痪(脑瘫)儿童下肢异常姿势的影响。方法:对呈屈膝蹲行步态痉挛型脑瘫28例儿童穿戴FRAFO前、后下肢关节运动参数进行分析,并以膝关节最大伸展角度分为两组,穿戴FRAFO后组间进行对比。结果:对比赤足,脑瘫儿童佩戴FRAFO后,站立期膝关节伸展角度显著增大、踝关节背屈角度明显减小,踝关节活动度显著缩小,其中膝关节伸展角度由-25.34°±13.37°增至-16.62°±12.83°(P<0.01),踝关节背屈角度由16.41°±8.31°减少至9.58。±4.75°(P<0.01),踝关节活动度范围由20.12°±8.25°缩小至9.71°±4.28°(P<0.05)。I组膝关节屈曲改善效果对比于Ⅱ组有显著差异(P<0.05)。结论:佩戴FRAFO限制学龄期脑瘫儿童异常的踝关节活动,明显增加站立期膝关节伸展角度,改善屈膝蹲行步态。FRAFO矫正膝关节屈曲异常的效果与膝关节最大伸展角度相关。
The Relationship between Jurassic Coal Measures and Sandstone-type Uranium Deposits in the Northeastern Ordos Basin, China

Outcrop and drill hole data show that the Jurassic coal measures in the northeastern Ordos Basin are composed mainly of the Yan’an Formation and the lowstand system tract of the Zhiluo Formation, and there is a regional unconformity between them. The Dongsheng uranium deposit is associated with the Jurassic coal measures. Research data indicate that the Jurassic coal measures in the study area have a certain hydrocarbon-generating capacity, although the metamorphic grade is low (Ro=0.40%–0.58%). In the Dongsheng region alone, the accumulative amount of generated coalbed methane (CBM) is about 2028.29 × 10~8 –2218.72 × 10~8 m~3; the residual amount is about 50.92 × 10~8 m~3, and the lost amount is about 1977 × 10~8 m~3. Analysis of the burial history of the host rocks and the evolutionary history of the Dongsheng uranium deposit suggests that the Jurassic coal measures generated hydrocarbon mainly from Middle Jurassic to Early Crataceous, which is the main mineralization phase of the Dongsheng uranium deposit. By the Late Cretaceous, a mass of CBM dissipated due to the strong tectonic uplift, and the Dongsheng uranium deposit stepped into the preservation phase. Therefore, the low-mature hydrocarbon-containing fluid in the Jurassic coal measures not only served as a reducing agent for the formation of sandstone-type uranium deposits, but also rendered the second reduction of paleo-interlayer oxidation zone and become the primary reducing agent for ore conservation. Regional strata correlation reveals that the sandstone-type uranium reservoir at the bottom of the Zhiluo Formation is in contact with the underlying industrial coal seams in the Yan’an Formation through incision or in the form of an unconformity surface. In the Dongsheng region with poorly developed fault systems, the unconformity surface and scour surface served as the main migration pathways for low-mature hydrocarbon-containing fluid migrating to the uranium reservoir.
