A SSDF-Attack-Exclusion Cooperative Spectrum Sensing Scheme in Cognitive Radio Networks
Authors: Wu Wei , Zhang Xiao Fei , Chen Xiao Ming
Published: May 2014

Compared with the single user spectrum sensing, cooperative spectrum sensing is a promising way to improve the detection precision. However, cooperative spectrum sensing is vulnerable to a variety of attacks, such as the spectrum sensing data falsification attack (SSDF attack). In this paper, we propose a concise cooperative spectrum sensing scheme based on a reliability threshold. We analyze the utility function of SSDF attacker in this scheme, and present the least reliability threshold for the fusion center against SSDF attack. Simulation results show that compared with the traditional cooperative spectrum sensing scheme, the SSDF attacker has a much lower utility in our proposed scheme, which drives it not to attack any more.

An Information Propagation Model for Instant Messaging with Group
Authors: Ding Feng , Yu Zhi Han , Hao Cui Cui , Li Zhi Jun
Published: May 2014

In this article, an information propagation model for instant messaging with group is constructed to research the group influence on information propagation in instant messaging network. The feature of group is if a group member propagates a message in a group, the other members in the same group will have a chance to receive this message. There are 4 kinds of nodes in instant messaging network: 1, N0, hasn’t received the message; 2, N1, has received the message, but hasn’t opened it yet; 3, N2, has opened the message, but hasn’t retransmitted it yet; 4,N3, has already opened the message and has retransmitted the message. When a message is propagated into the network, the group influence on information propagation in instant messaging network is revealed by changing the size of each group and the number of groups. The conclusion: the information propagation efficiency of instant messaging network with group is much higher than normal instant messaging network. When the size of each group is very small and the number of groups is very little, the influence of them on information propagation is not very obvious. With the growth of the size of each group and the number of groups, the information propagation is more and more widely and quickly.

Longcha highway was a part of highway from Quanzhou city, Hujian province to Nanlin city, Guangxi Zhuang Autonomous Prefecture. In order to dissolve and match with around natural landscape, restore the landscape and environment of red sandstone, the red sandstone slope was investigated. The results showed that the slope of red sandstone was not suitable for the plant. Several measures were taken for the restoring the landscape and plants. First, dig planting groove in the appropriate place on the slope. Second, transplant or grow some plants in the planting groove. Third, plants were planted in the planting groove. Fourth, the slope could be restored by planting lawn. Some shrubs were planted in the lawn. Fifth, the slope was sprayed and sowed with the seeds of shrub. Sixth, the slope was coved with native grass stem tuber.

Based on the immersion quenching cooling used at steel bar, numerical simulation about temperature field of big GCr15 bearing steel bar is carried out by the FLUENT. The influence on temperature field uniformity brought by different elements during the immersion quenching cooling is analyzed, such as the number and the diameter of the nozzle when the total cross-sectional area is constant and the distance between the nozzle and the surface of the steel bar. The results show that: a better uniformity of the temperature would be achieved when the number of the nozzle is 11and the diameter of the nozzle is 26mm.when the distance between the nozzle and the surface of the steel bar is 250mm, a better uniformity of the temperature would be gained.

Wall insulation material can save a lot of wall materials, improve the performance of the wall insulation, save resources, and reduce environmental pollution, which is a new material for interior and exterior wall insulation. In order to study the insulation performance of insulation material, according to the construction process of insulation material, we design the multi-layer insulation wall structure. In order to verify the insulation effect of energy saving, we use the FLUENT software to do numerical simulation on the wall insulation effect, and establish the heat transfer equation of the radiation and solid. We use the CAD software to design large building model, and use GAMBIT to carry on the grid division, finally get the 2D and 3D temperature distribution by means of numerical calculation. Through the finding of thermal efficiency and energy-saving efficiency, insulation wall can significantly improve the energy performance of buildings, which provides technical support to study the energy saving and environmental protection of building.
Environmental Impacts Analysis and Evaluation for Sand Casting
Authors: Yin Rui Xue
Published: May 2014

According to the analysis of the I/O flow of the sand casting process, the paper divides the process into five stages. The carbon emission is used to describe the environmental impacts of sand casting, which is defined as energy carbon emission, material carbon emission and direct carbon emission, and then the carbon emission evaluation model is molded. Taking the actual cast as an example, the main influencing factors of the carbon emission and emission sources during the iron work carbon emission can be identified by the evaluation model.

In order to research on the effect of composition ratio on drying quality of the plant bowl-seeding tray, the drying test was done in superheated steam drying test-bed, the regression model was established by performance test data, and the best composition ratio was obtained from optimization results, the best composition ratio is 21:7:1:4, at this condition the dry strength value was 0.2112MPa, the wet strength value was 0.2178Mpa. The research results has important meaning to enhance the drying quality of the rice seedling-growing tray made of paddy-straw and to promote planting techniques of bowl sterile.

The compounds, which extracted from Equisetum arvense, Crataegus pinnatifida Bunge, Rosa maximowicziana Regel and Physalis alkekengi, were selected to determine the content of flavonoids and polysaccharides by a visible light spectrophotometry, and the antioxidant activity was determined by a chemical method. The results showed that the content of flavonoids in our compounds was 0.204 mg/g and the polysaccharides was 2.498 mg/g. In scavenging experiments, the levels of hydroxyl radicals and superoxide anion were lower compared with negative control, but the levels were still higher than positive control. The ability to scavenge superoxide anion was more powerful than hydroxyl radicals. This determined that our compound preparation extract have the ability to scavenge hydroxyl radicals and superoxide anion.

To investigate the therapeutic measures and clinical efficacy of mycoplasma mixed infection in children with pneumonia. We selected the pediatric ward of our hospital from February 2010 to February 2012, 106 patients received hospital treatment MP pneumonia cases, the patient specimen collection and virus detection, analysis and its clinical manifestations and treatment. Different kind of different ages in children with mycoplasma pneumonia infection mixed. MP childhood pneumonia combined with other pathogens than a simple MP infectious pneumonia symptoms is heavier, duration longer. In terms of treatment, diagnosis of MP infection, should be applied as soon as possible the effects of the macrolide antibiotic azithromycin treatment, treatment was combined with other pathogens, done immediately virological testing, chlamydia and sputum culture examination should be considered, according to the corresponding inspection.
