Published: May 2014

A cooperative wideband signal detection approach in deep space communication is designed in this paper. In order to implement autonomous communication between explorers, detectors and satellites, we need to detect signal in advance. There are sparse active signals in the shadowing deep space environment, whose frequency support only occupies a small portion of a wide spectrum. Compressed sensing (CS) is a new technique which is able to utilize the sparsity of deep space communication signal. Wideband signal is sampled one time only with low sampling rate, and then signal spectrum is recovered by reconstruction algorithms. A discrete cosine transform (DCT) based compressed spectrum detection method has been studied which can significantly improve the probability of signal detection. Simulation result show the effectiveness of our new detect scheme in deep space communication.

Authors: Xiao Jun Jie , Li Dong Sheng , Li Xiao Qiang , Xu Ming Jin
Published: May 2014

In order to reduce the energy consumption and working procedure for manufacturing thin-walled titanium alloy components, a hot stretch-creep forming (SCF) technique via resistance heating is proposed to form the hard-to-form material. Firstly, the principle of hot SCF was introduced that the technique can manufacture titanium alloy components precisely because the residual stress relaxes in the material during the dwelling time. Secondly, the hot SCF equipment via resistance heating was developed, which makes use of electrical current for heating the titanium materials to improve their ductility. Then based on a set of optimized process parameters, including forming temperature, stretch velocity, post stretch percentage and dwelling time, a comparative experment of single curvature Ti-6Al-4V alloy sheet components was conducted via this innovative technology to examine the hot SCF equipments and the effect of creep forming. Results show that the component precision of the hot SCF is more precise than that of the hot stretch forming (SF) due to the creep in the stress relaxation period. Comparing to the as-received material, the yield strength of the material suffered hot SF decreases a little; while the strength suffered hot SCF increases a little. This novel technique shows a promising future to manufacture titanium sheet or profile components precisely as a feasible and cost-effective way.

Authors: Wang Dan , Deng Xue Mei , Ni Xin
Published: May 2014

In order to avoid dropping the SRS report frequently in case of collision between SRS and a periodic CSI report in LTE-Advanced system, this paper gives shortened PUCCH (Physical Uplink Control Channel) format 2/2a/2b for multiplexing SRS (Sounding Reference Signal) with periodic CSI (Channel State Information). The result of simulation shows that the shortened PUCCH format 2/2a/2b can effectively support simultaneous transmission periodic CSI and SRS. What’s more, on shortened PUCCH format 2/2a/2b with the first and last two encoded bits punctured, periodic CSI and HARQ-ACK feedback have the same performance as on PUCCH format 2/2a/2b without multiplexing SRS. Hence through the shortened PUCCH format 2/2a/2b, we can not only enhance simultaneous transmission of periodic CSI and SRS, but also guarantee the similar performance of periodic CSI and HARQ-ACK feedback as transmitting them on PUCCH format 2/2a/2b without multiplexing SRS.

Simulating stage scenery by using auto accompaniment software can reduce their stress and tension and improve their level of singing. Doing composing practice by using music software can improve learning efficiency. "TT composer" make electronic composing more intuitive, more easily.

Published: May 2014

This paper investigates the interlaminar stress distributions of notched angle-ply thermoplastic laminate under tension numerically. The representative AS4/PEEK laminate with configuration of was studied by finite element code ANSYS. Computation results show: The interlaminar stress concentrations are evident and localized in the vicinity of the hole and the two free sides, and the maximum values always appear near the hole. Meanwhile, at interfaces of-45/+45 and +45/0, the concentration of peel stress is evident, while at interfaces of 90/-45 and 0/90, the concentration of shear stress is evident. Further analysis demonstrates interlaminar shearing stress is the dominating stress and may be the leading cause of laminate delamination.

Published: May 2014

Experimental, analytical and finite element techniques are commonly known methods used in determining highly localized stress occurring in the body under loading as a result of geometric discontinuities. In this study, we use NURBS-based isogeometric analysis (IGA) to investigate the stress concentration factor (SCF) on three-dimensional geometry with discontinuity feature. The results show that IGA technique is in good agreement with analytical values, thus providing a more effective realistic way of determining SCF.

Urban rail transit will have a direct impact on the land use types and structure. This paper mainly focused on Wuhan rail transit line 1, Using 2002、2010 Wuhan local remote sensing image, based on RS and GIS techniques, the transfer matrix of land use around the orbit is achieved by analyzing the land use data in two different periods before and after the urban rail system run, and then based on the markov model to quantitatively forecast the change of land use types between 2013 and 2018. The results showed that, Wuhan rail transit increased the strength of the development and the degree of land use along it, accelerated the mutual transformation between the land use types, changed the land use structure and land cover types along it, in which the construction lands and roads were mainly come from cultivated lands and green lands.
The Polarization Properties Research of Atmospheric Based on Actual Weather Conditions
Authors: Zhang Fei , Du Xiao Ping , Wang Shen
Published: May 2014

A new method to calculate the polarization properties of the atmosphere by combining the Rayleigh scattering and Mie scattering is proposed in this paper. We inversed the values of the required data by experiment and simulated of the atmosphere polarization characteristics under the same conditions. The simulation results show that the proposed method can accurately describe the variation of the atmosphere polarization properties. Besides, the results show such variation: in the same weather conditions, the degree of polarization is gradually increased while scattering angle is gradually increased as 90°; in the same detect conditions, the degree of polarization decreases with the deteriorating weather conditions.
The Sacrificial Anode Cathodic Protection of Reinforced Concrete Structure in the Splash Zone
Authors: Li Sen Lin , Zhao Jie
Published: May 2014

Corrosion of reinforced concrete structure in the marine environment is easily happened because of the influence of chloride ion, and the corrosion in the splash zone is the most serious. Cathode protection is the most common and effective way in anticorrosion method. For simple steel structure, anticorrosion technology has been basically mature[1].But for some complex marine engineering structures, many key technologies have not been resolved, which constraints the design and construction of such facilities. In this paper, combined the experiments and the research of the model piles of the coal wharf of Rizhao Port, the sacrificial anode protection technology has been introduced and some problems have been solved, such as the relevant operation technologies, parameter design, material selection and so on.
