CdO-Ga2O3 alloy films (Cd1-xGaxO1+δ) over the whole composition range (x=0 to 1) were synthesized by room temperature radio frequency magnetron sputtering. We found that the intrinsic band gap of these alloys can be tuned in a wide range from 2.2 to 4.8 eV. As the Ga content increases to x>0.3 the alloy becomes entirely amorphous and the resistivity increases from 10−3 to 10−1 ohm-cm while the...
Mixing of different materials is routinely used to create alloys or composites with new functionalities and properties tailored for specific applications. We have synthesized a uniform stoichiometric composite of CdO and SnTe, two compound semiconductors with distinctly different electrical properties and electronic band structure. The carrier concentration in the composite varies from about 1020...
Starting from influential factors of fixed traffic bottleneck and choosing appropriate identifying indices for fixed transportation bottleneck, we get MapReduce parallelized processing method of K-means clustering algorithm after full investigations on parallel programming pattern and clustering algorithm; Finally, the recognition approach for fixed traffic bottleneck is proposed based on K-clustering...
In this paper, we investigate how to select the best access network efficiently for Low-Power Mobile Terminal (LPMT) when move in integrated WLAN/UMTS environment. A novel network selection mechanism based on adaptive weight adjustment is proposed in order to further reduce unnecessary handoff and extend battery lifetimes of low-power mobile terminal. We construct a novel multi-objective optimization...
A new adaptive pulse compression (APC) method has been proposed in this paper in order to restrain the mutual interference of the orthogonal transmitted waveforms. Based on the minimum power distortionless response (MPDR) this method is combined by the generalized sidelobe canceller (GSC) structure and the multistage wiener filter (MWF), which not only does not calculate the covariance matrix of signal...
Color and shape features have difficulty to recognize fire from fire-colored, irregular-shaped and moving objects. An effective algorithm using texture analysis with the Local Binary Pattern (LBP) is proposed in our paper to help deal with this problem. Besides grayscale and rotation invariance, the ability of LBP operator for multi-resolution analysis is enhanced through multiple LBP operators with...
This paper preliminary discusses the genetic diversity and differentiation from 9 populations of wild Cyclinasinensis, which distribute in different regions around maritime coasts of China. The investigation was carried out by sequencing ribosome DNA gene internal transcribed spacer 1 (ITS1) sequences. The ITS1 sequence of C.sinensis obtained in this research ranged from 564 to 595 nucleotides in...
