A novel low-profile Inverted-F Antenna (IFA) for tablet computer with complete metal-back cover operating in 2.4 GHz (2412–2472 MHz) and 5.8 GHz (5725–5825 MHz) WiFi bands is presented. The height of the proposed antenna is just 3 mm. Owing to the simplicity if IFA design, the proposed antenna can operate as a quarter-wavelength IFA structure at 2.4 GHz, and a half-wavelength loop structure at 5.8...
With network coding, data flows from the source to the destinations may be jointly coded in some intermediate nodes to achieve the maximum network capacity. There is scarcely any theory to systematically model and evaluate the loss of network coding. Without such a theory, the analysis of network coding under various settings is far from practical. To fill the vacancy, we introduce a loss model into...
As a necessary way of sustainable development in the construction industry, Green construction have become consensus in academia and industry. Points out that the domestic problems in the development of green construction and analysis of its causes, and put forward some development strategy: strengthening the functions of the Government tovigorously promote green construction; Increase the intensity...
Identifying gene regulatory network (GRN) from time course gene expression data has attracted more and more attentions. Due to the computational complexity, most approaches for GRN econstruction are limited on a small number of genes and low connectivity of the underlying networks. These approaches can only identify a single network for a given set of genes. However, for a large-scale gene network,...
The Research of detection malware using machine learning method attracts much attention recent years. However, most of research focused on code analysis which is signature-based or analysis of system call sequence in Linux environment. Obviously, all methods have their strengths and weaknesses. In this paper, we concentrate on detection Trojan horse by operation system information in Windows environment...
A simple and compact approach for tunable microwave frequency generation based on dual-polarization distributed Bragg reflector fiber laser is demonstrated. The beat tone frequency changes linearly with the voltage applied to piezoelectric transducer.
Acoustic emission testing technique is a dynamic testing technology. In this paper, the relationship between the cumulative energy of acoustic emission and lower cycle reversal loads is studied based on results of the experiments on underwater concrete columns, and waveform acoustic emission signal of different destruction states is picked up. Spectrum analysis is carried out, the results of which...
In order to avoid the blocky effects of second-order PDE model and preserve edges, a new fourth-order PDE model was proposed in this paper. Based on four-neighbor system, a simple and symmetrical difference scheme was also developed to make the model more efficient and reliable. Median filtering was utilized to alleviate the speckle effects in the processed image at last. We remove the Gaussian noises...
Based on commercial CFD software Fluent, the flow field in a turbulent contact absorber (TCA) is simulated under the condition of no fillers and the simulation precision with different mesh interval sizes, k-epsiv models and boundary conditions is investigated respectively. By comparing the numerical results of air flow with experimental data, the simulation accuracy reaches highest at the condition...
