The Influence Factors Study of Aerosol Particles  [PDF]
Tao Jiang, Wu Wei
Modern Mechanical Engineering (MME) , 2013, DOI: 10.4236/mme.2013.32014
Abstract:

The marine and coastal intake filtration device is mainly used to filter out the salt spray aerosol particles. So, the laboratory studies of the intake filtration device need to simulate the salt spray aerosols state of the ocean environment. But the distribution of ocean salt spray aerosol particle of diameter is very wide, so the simulation device of salt spray aersol should produce a variety of salt spray aerosol particles. The paper is to mainly study the influencing factors of salt spray aerosol device to produce different particles diameter. And the investigation and study mainly include two aspects: numerical simulation and experimental study.

(E)-2-(Benzyliminomethyl)-4,6-dibromophenol
Wei Jiang
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808019247
Abstract: The title compound, C14H11Br2NO, was prepared by the condensation of benzylamine and 3,5-dibromo-2-hydroxybenzaldehyde. The crystal structure is stabilized by aromatic π–π stacking interactions between the phenol rings of neighbouring molecules [centroid–centroid distance = 3.530 (5) ]. In addition, the stacked molecules exhibit intermolecular C—H...π and intramolecular O—H...N interactions.
The Application of the Fuzzy Theory in the Design of Intelligent Building Control of Water Tank
Wei Jiang
Journal of Software , 2011, DOI: 10.4304/jsw.6.6.1082-1088
Abstract: With the rapid development of intelligent buildings, a lot of researchers have found that it is difficult to establish mathematical model when the problem that energy-saving in water supply system of an intelligent building tank is focused, because that the outflow of the tank volume is volatile when the water is daily living water. In this paper, fuzzy control theory is used to establish a fluid level, and the fluid input flow rate to determine the amount of control, which to push the valve’s opening size and speed in order to control the water supply valve opening adjustment level, so that the liquid position of container maintains a constant, and the MATLAB software is used to verify the effect of fuzzy control system. The results show that in this fuzzy control system the benefits of economic operation of water supply can be ensured by ensuring a constant level of liquid.
Automated Scoring Research over 40 Years: Looking Back and Ahead
Jinlin Jiang,Wei Wei
Journal of Artificial Intelligence , 2012,
Abstract: This study reviews the developments of automated scoring systems and techniques over the past 40 years and the strengths and weaknesses of each technique are analyzed in detail. Results of the study showed that automated scoring systems are becoming more complicated and advanced by the integrated use of knowledge in natural language processing, statistics, information retrieval, corpus linguistics, etc. but they still have drawbacks in one or two aspects. The study provides some valuable insights into further studies in this line.
Experimental Studies on the Influence of HCO3- on Absorption and Desorption of CO2 from Ammonia Solution  [PDF]
Shaojian Jiang, Wei Zhong, Rui Peng, Yong Jiang, Jun Zhang
Advances in Materials Physics and Chemistry (AMPC) , 2012, DOI: 10.4236/ampc.2012.24B061
Abstract: With aqueous ammonia in the process of CO2 absorption and desorption to join sodium bicarbonate, the influence of HCO3- on CO2 absorption and desorption from ammonia solution was investigated through the experimental analysis of the desorption quantity of CO2, desorption rate, CO2 loading and the absorption rate. The experimental results showed that, in experimental conditions, The desorption rate decreased gradually with increasing ammonia concentrations. The desorption rate increased 12%, 17%, 19% and 28.8% when 1 mol/L of ammonia solution is added in 0.1 mol/L, 0.3 mol/L, 0.5 mol/L and 1 mol/L of sodium bicarbonate. The higher concentration of ammonium bicarbonate solution which was added sodium bicarbonate,the more observably the effect of CO2 desorption was promoted. The absorption rate had dropped when absorption process added 0.3 mol/L sodium bicarbonate, the CO2 loading was a little change.
The Research Progress of Long Noncoding RNAs in Nasopharyngeal Carcinoma  [PDF]
Pei Li, Boyu Wu, Tao Jiang, Wei Jiang, Weiguo Huang
Journal of Cancer Therapy (JCT) , 2017, DOI: 10.4236/jct.2017.88065
Abstract:
Long noncoding RNA (lncRNA) is a leader of the degree of more than 200 nucleotides, almost do not have the function of protein coding endogenous RNA molecules. Recent studies show that, lncRNA is not encoded protein, but it has a wide range of biological functions, and lncRNA in human diseases, especially in oncology, more and more attention has been paid to its role. Nasopharyngeal carcinoma (NPC) is a common malignant tumor of the head and neck in South China, which poses a serious threat to people’s health and life. Studies found that lncRNA is widely involved in the invasion, metastasis and prognosis of nasopharyngeal carcinoma (NPC). In this article, we will review the research progress of lncRNA in nasopharyngeal carcinoma.
Pinning Forces in Superconductors from Periodic Ferromagnetic Dot Array  [PDF]
Wei Jiang Yeh, Bo Cheng, Tony Ragsdale
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.16052
Abstract: Using the London equation, we derive a formula by which the pinning force from magnetic dots can be cal-culated. We numerically calculate the interaction between ferromagnetic dots and vortices in type II super-conductors under various conditions. It is found that the pinning force of the magnetic dot with 50 nm thick-ness reaches 3.5 × 10-11 N that is one order magnitude stronger than the intrinsic pinning force in cuprate at 77 K. We investigate various parameter dependences of the pinning force. It is found that the most effective way to increase the pinning force is to increase the thickness of the dot. The pinning force is weakly de-pendent on both the size and magnetic permeability of the dots. When temperature increases, the pinning force linearly decreases. And when the magnetic field increases, the attraction force increases linearly in the low field region.
Generalized Likelihood Ratio Tests for Varying-Coefficient Models with Censored Data  [PDF]
Rong Jiang, Wei-Min Qian
Open Journal of Statistics (OJS) , 2011, DOI: 10.4236/ojs.2011.11003
Abstract: In this paper, we extend the generalized likelihood ratio test to the varying-coefficient models with censored data. We investigate the asymptotic behavior of the proposed test and demonstrate that its limiting null distribution follows a distribution, with the scale constant and the number of degree of freedom being independent of nuisance parameters or functions, which is called the wilks phenomenon. Both simulated and real data examples are given to illustrate the performance of the testing approach.
Evolution of Internal Crack in BCC Fe under Compressive Loading  [PDF]
Dongbin Wei, Zhengyi Jiang, Jingtao Han
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.310197
Abstract: A molecular dynamics model has been developed to investigate the evolution of the internal crack of nano scale during heating or compressive loading in BCC Fe. The initial configuration does not contain any pre-existing dislocations. In the case of heating, temperature shows a significant effect on crack evolution and the critical temperature at which the crack healing becomes possible is 673 K. In the case of compressive loading, the crack can be healed at 40 K at a loading rate 0.025 × 1018 Pa·m1/2/s in 6 × 10-12 s. The diffusion of Fe atoms into the crack area results in the healing process. However, dislocations and voids appear during healing and their positions change continuously.
