An Application of Fiber-Connected Distributed Antennas to Heterogeneous Networks : Energy Efficiency Perspective

Ying Sun,Yuxian Huang,Liming Chen 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.1

Fiber-connected distributed antenna systems (DAS) have been recognized as an effective means to accommodate the coverage and capacity demands of future heterogeneous networks (HetNet). Among various opportunities realized by the architecture, our focus in this paper is on the spectral efficiency (SE) advantages achieved by cooperative transmission and the associated power consumption that may affect the energy efficiency (EE) of the system. A detailed power model is developed to benchmark the various sources of energy consumption in fiber-connected DAS. Then a simple but efficient pre-coding scheme is proposed to reduce the computation complexity associated with cooperative transmission, thus lowering the power consumed by baseband processing while at the same time maintaining a high throughput performance. Through detailed and extensive simulations, this paper demonstrates the SE and EE advantages of the application of fiber-connected DAS in HetNet.

Xiaole Huang,Yu Ding,Wennian Xu,Shiyuan Xiong,Liming Liu 대한토목학회 2021 KSCE JOURNAL OF CIVIL ENGINEERING Vol.25 No.12

Fibers have been widely applied to improve the mechanical properties of natural soil and traditional cemented soils, but rarely investigated in substrates for slope eco-protection. Vegetation-growing concrete (VC) substrate is a kind of ecological cemented soil and has very wide popularization and application prospects. In this study, unconsolidated-undrained (UU) triaxial compression tests were conducted on the control specimens of VC substrate containing three cement contents and the palm fiber reinforced specimens manufactured by adding four fiber contents. The control specimens were shown to possess increasing yield strength, ultimate strength, yield strain and shear modulus with cement content, which resulted from the cemented texture improved by the hydrate products as recognized previously. Instead of inextensible reinforcement provided by cement, the palm fibers were found to provide extensible reinforcement, through which the obvious softening behavior of VC substrate could transfer to elasto-plasticity. Attributed to the unique ductility, the fibers added could bring with considerable increase in ductility of reinforced substrate, except for additional increases in yield strength, ultimate strength and yield strain.

Wei Liming,Fu Shan,Huang Dan 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

The pilot model concerning human factors introduced non-linear and time delay into the pilot-aircraft system. Unfalsified adaptive control (UAC), which is one kind of data-driven control, uses input and output data only. In UAC, supervisor is designed for selecting the best controller and controller switching algorithm is executed when necessary. In this paper, unfalsified adaptive PI controller, with linearly increasing cost level algorithm (LICLA) is used for the system. Monte Carlo simulation is taken at the end of the paper. The result shows the designed controller increase the flight performance.

Error Analysis of Multidimensional Evaluation of Pilot’s Workload Based on Objective Measures

Chan Wei,Liming Wei,Zhengxiang Cai,Yanyu Lu,Qi Wu,Dan Huang,Shan Fu 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

Evaluation of pilot’s workload during flight is a significant consideration for the safety of civil aviation. However, some errors may be brought in the measurement and the recording of objective parameters. Based on a multidimensional workload evaluation, the time delay of cardiac activity and its impacts on workload are analyzed. The results suggest that within a certain limit of error around 10s, varying from individual to individual, workload can keep the main information compared to the original workload. As the error increases, the workload may become unreliable. As a consequence, the time-delay error of cardiac activity should be controlled in a limited scale to ensure the validity and reliability of workload.

Case Study on Rock Support Technology for Roadways Based on Characteristics of Plastic Area

Chao Yuan,Liming Cao,Wenjun Wang,Lei Fan,Cong Huang 대한토목학회 2021 KSCE Journal of Civil Engineering Vol.25 No.2

Rocks surrounding deep, high-stress roadways typically undergo a vicious cycle of destruction → repair → re-destruction → re-repair over a long time. This article uses the roadway restoration project of Pingmei Mine No. 6 (400 m underground) as research object. Starting from the plastic area, the characteristics of the distribution of rock surrounding the circular roadway are analyzed, and the influence of the side pressure coefficient, cohesive force, inside friction angle, support strength, and roadway radius on the plastic area is studied. Four types of distribution patterns were observed in rocks surrounding the plastic area of the roadway: round, oval, rounded rectangle, and butterfly. The side pressure coefficient, cohesive force, and inside friction angle affected the distribution and range of rocks surrounding the plastic area of the roadway. The support radius of the roadway and the support strength of its face did not change the distribution of the plastic area, but only affected its size. Therefore, to maintain the long-term stability of weak and broken roadways, the strength of the surrounding rocks must be increased, and roadway renovation should be avoided as it affects the distribution of the plastic area and reduces its scope. Engineering practice has shown that the “anchor net spray + hollow grouting anchor cable” technology for the combined, step-by-step repair and support of roadways, with a hollow grouting anchor cable as core, can suppress the distribution and scope of the plastic area to guarantee safe and long-term use of the roadway.

A Recommendation Method basing on Synthetic Strategy for Agricultural Science and Technology Information

Song Jinling,Huang Liming,Gao Yan,Liu Aiyong,Liu Haibin 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.5

To ameliorate the limitations of traditional collaborative filtering technologies and enhance the recommendation quality of agricultural science and technology information, a collaborative filtering recommendation method based on synthetic strategy is proposed. Firstly, filter the user set and user-item rating matrix according to the location of target user, which can solve the regional problem. Then, predict ratings of items according to the similarity of users or item content, which can relax the impact of the sparse rating. In addition, add the rating time to the user-item rating matrix to distinguish the timeliness of the user preference, and add user preference shifting in the similarity formula as a factor which can express the similarity of users or item content better. Our method can not only guarantee the recommended information is local and suit to current season of agricultural production, but also ensure the recommending precision under sparse rating data.

Liu Changqi,Tao Kai,Huang Liming,E Dejun,Bai Xiaohou,Ma Zhanwen 한국원자력학회 2024 Nuclear Engineering and Technology Vol.56 No.5

The fission model, G4ParaFissionModel, was enhanced in this study, mainly focusing on refining the energy dependence of the peak-to-valley ratio in the mass distribution and the energy dependence of the average total kinetic energy (TKE). The enhanced model was employed to investigate the characteristics of fission products from 235U(n, f) reaction. The calculated results, including fission yield, TKE distribution, prompt fission neutron and gamma spectra, were compared with both evaluated and experimental data. The comparison shows that these physical observables related nuclear data, which are of importance for developments of the nuclear power and physics, can be reasonably well reproduced.

Sparse Principal Component Analysis For Feature Selection of Multiple Physiological Signals from Flight Task

Dongbo Bai,Wei Liming,Wei Chan,Qi Wu,Dan Huang,Shan Fu 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

Sparse principal component analysis (SPCA) imposes extra constraints or penalty terms to the standard PCA to achieve sparsity. In this paper, we introduce an efficient algorithm for finding an effective sparse feature principal component (PC) of multiple physiological signals. The algorithm consists of two stages. In the first stage, it identifies an active index set with a desired cardinality corresponding to the nonzero entries of the PC. In the second one, it uses the power iteration method to find the best direction with respect to the active index set. Experiments on randomly generated data and multiple physiological signals datasets show that our algorithm is very fast, especially on large and sparse data sets, while the numerical quality of the solution is comparable to the state-of-art algorithm.

Influence of Al Addition Upon the Microstructure and Mechanical Property of Dual‑Phase 9Cr‑ODS Steels

Xiaosheng Zhou,Zongqing Ma,Liming Yu,Yuan Huang,Huijun Li,Yongchang Liu 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.1

With Al addition, dual-phase oxide dispersion strengthened (ODS) steels consisting of martensite and ferrite are fabricatedby spark plasma sintering. It is found that Al addition has a negligible effect on martensite lath size, while the amount andsize of ferrite grains are related to the Al content. M23C6(M = Fe, Cr) carbides have been identified within the ferrite grainsor along ferrite boundaries. With increasing Al concentration, more fine Y–Al–O oxide nanoparticles are formed. Uponannealing treatment, homogeneous and refined distribution of ferrite grains is obtained, which may involve the particlestimulatednucleation of recrystallization caused by the large sized M23C6. As Al is increased from 0.05 to 0.1 wt%, thetensile strength of the annealed steel is decreased, as well as its ductility. For the annealed 9Cr-ODS steel containing 0.1 wt%Al, in tensile loading the large sized M23C6along ferrite boundaries would facilitate the cracking along boundaries betweenthe hard annealed ferrite and soft annealed martensite, producing the mixed fracture of dimple and intergranular fracture.
