Computer Science , 2015,
Abstract: For the problem whether Graphic Processing Unit(GPU),the stream processor with high performance of floating-point computing is applicable to neural networks, this paper proposes the parallel recognition algorithm of Convolutional Neural Networks(CNNs).It adopts Compute Unified Device Architecture(CUDA)technology, definite the parallel data structures, and describes the mapping mechanism for computing tasks on CUDA. It compares the parallel recognition algorithm achieved on GPU of GTX200 hardware architecture with the serial algorithm on CPU. It improves speed by nearly 60 times. Result shows that GPU based the stream processor architecture ate more applicable to some related applications about neural networks than CPU.

Abstract: AIM: To investigate the ultrastructure of the basal vitreo- retina interface in enucleated pig eyes after vitreous injection of enzymes. METHODS:Totally 130 eyes were obtained from freshly slaughter pigs and divided into 5 groups. Each group was sub-divided into the 15 minutes group and the 30 minutes group, with 13 eyes in each group. The control group were performed middle vitreous injection of 0.1mL PBS, 200U/mL and 800U/mL hyaluronidase(HA)were injected in groups A and B, 10U/mL and 50U/mL chondroitinase(CA)in groups C and D. After incubation for 15 minutes and 30 minutes, the eye balls were fixed with 4% glutaraldehyde and retina fixative solution. Pathological examination, eosin-hematoxylin staining, scan electron microscopy were taken to evaluate the remaining vitreous on vitreous base, transmission electron microscopy to evaluate retina toxicity. RESULTS:Both of gross appearance and hematoxylin+eosine slice all revealed basal vitreous partially liquefied and degradation. Remarkably decrease was found in basal vitreous than the control group both in the HA 800U/mL group and the CA 50U/mL group when using electron microscopy scanning. Transmission electron microscopy in group B, C and D revealed the remaining vitreous were less than the control group. CONCLUSION: Both CA and HA can cause basal vitreoretinal detachment in enucleated pig eyes. But the HA may cause less damage to the retina.

Abstract: In the traditional characteristic waveform interpolation speech coding, the high frequency harmonics of the synthetic speech are usually lost, which makes the speech feel noisy, due to the phase information neglect of the characteristic waveform and the whole characteristic waveform alignment. In order to improve the synthetic speech quality, the multiband surd/sonant flag is first introduced. The phase spectrum of the slowly/rapidly evolving waveform is estimated with the waveform interpolation speech coding model depending on the multiband surd /sonant flag. Then the partial characteristic waveform alignment is used in the speech synthesis section and a 2.4 kbit/s multiband waveform interpolation speech coding algorithm is proposed finally. Compared with the traditional characteristic waveform algorithm, the new algorithm can distinctly improve the speech definition. Compared with the standard 2.4 kbit/s MELP algorithm, the synthetic speech quality is also slightly better.

Abstract: 为了弥补移动IP不能支持主机高速移动的缺陷,提出了一种分布式动态型微移动管理方案.该方案在网络中放置多个区域移动代理来实现分布式的域内主机移动管理,并提出一种由主机根据自身的移动特点及获悉的网络参数动态地选择区域移动代理和区域大小的算法,该算法使得主机在域内产生的信令代价和分组传递代价达到最小,且没有对网络拓扑结构和区域移动代理的位置做任何强制性要求.分析表明,当主机的平均分组到达率增加时,区域大小减小而总代价增加;当主机在接入路由器的平均驻留时间增加时,区域大小和总代价均减小.最后,在与分层移动IPv6方案的性能比较中发现,分层移动IPv6方案在几种不同区域大小情况下产生的总代价都比该方案可能产生的最大总代价要高.

Abstract: The effects of sod cultivation in orchard on distribution of organic carbon in soil aggregates were investigated, which located in Yuchi Village, Youxi Xian, Fujian Province. The results showed that compared with downslope and landings clean tillage orchards, the proportion of >0.25 mm water-stable aggregate (R0.25), mean weight diameter (MWD), and geometric mean diameter (GWD) of soil aggregate at 0-20 cm soil layer in sod cultivation orchard increased by 3.78%-5.90%, 16.82%-20.94%, 5.86%-50.31% and 3.81%-13.82%, 13.33%- 19.95%, 7.50%-60.63%, and the fractal dimension decreased by 1.54%-2.35% and 1.09%-9.64%, respectively. The sod cultivation could improve proportion of organic carbon storage in large aggregates (>2 mm) to total organic carbon at 0-20 cm soil layer. Therefore, the sod cultivation was beneficial to improve stability of soil aggregate, and could enhance the protection of organic carbon and carbon sink in soil.
