Design and Stability Analysis of Fuzzy Switched PID Controller for Ship Track-Keeping  [PDF]
Baozhu Jia, Hui Cao, Jie Ma
Journal of Transportation Technologies (JTTs) , 2012, DOI: 10.4236/jtts.2012.24036
Abstract: The fuzzy switched PID controller which combines fuzzy PD and conventional PI controller is proposed for ship track-keeping autopilot In this paper. By using rudder angle, the whole voyage is divided into two operating regimes which named transient operating regime and steady operating regime respectively. The fuzzy PD controller is employed in transient operating regime for increasing response, reducing overshoot and shorting transition time. And conventional PI controller is used to improve the stable accuracy in steady operating regime. The global controller is achieved by fuzzy blending of all local controllers. Routh stability criterion is utilized to obtain the stability condition of closed-loop system. The simulation results show the effectiveness of proposed method.
Research Advances on Th17 Cells in Tumor
Jiansheng WANG,Baozhu YUAN
Chinese Journal of Lung Cancer , 2011, DOI: 10.3779/j.issn.1009-3419.2011.11.10
Abstract: The Th17 cells, identified recently as a novel CD4+ T cell lineage, are characteristic of their production of IL-17 and distinct from Th1 and Th2 lineages. Their involvement in autoimmune and chronic inflammation diseases has been well observed. Recent evidence suggests that Th17 cells are also involved in tumor immunology. However, it remains unclear that how these cells regulate immune responses to tumor growth. In this review, we summarize the most recent findings about the biologics of the Th17 cells in tumor development with a hope of providing new insights into future development of effective new cancer immunotherapies.

Experimental Study of Invasion and Biofouling of Freshwater Mussel Limnoperna fortunei  [PDF]
Mengzhen Xu, Zhaoyin Wang, Cheng Chieh Lin, Baozhu Pan, Na Zhao

Golden mussel Limnoperna fortunei(Dunker 1857) is a filter-collector species of fresh water mussel originating from southern China. In the water transfer tunnels from the East River to Shenzhen and Hong Kong, golden mussels attach to the walls of pipelines and gates, causing serious biofouling, increased flow resistance, and resulted in corrosion of the tunnel wall. Golden mussel has very high environmental adaptability and may colonize habitats with low dissolved oxygen and a wide range of trophic levels. The colonization process of the species on solid surface was studied in the Xizhijiang River, a tributary of the East River and the main water resource of Shenzhen from March 2010 to April 2011. The results showed that the golden mussel completed three generations and reproduced six cohorts per year in the tropic zone. Water temperature was the controlling factor for the growth rate and maturity of each cohort. Based on the results, an ecological method for controlling the invasion of golden mussels in water transfer tunnels was proposed.

Maize silk antibiotic polyphenol compounds and molecular genetic improvement of resistance to corn earworm (Helicoverpa zea Boddie) in sh2 sweet corn
Baozhu Guo,Ana Butrón,Brian T. Scully
International Journal of Plant Biology , 2010, DOI: 10.4081/pb.2010.e3
Abstract: The flavor of sh2 super-sweet corn is preferred by consumers. Unfortunately, sh2 sweet corn has little genetic variation for insect resistance. In this paper we review the functions of two loci, p1 and a1. The P1 allele has a major role in sh2 sweet corn resistance to corn earworm, an allele that was lost in historical selection because of its pleiotropic effect on undesirable cob color and silk browning. The P1 allele has significant effects on biosyntheses of silk antibiotic compounds, maysin, apimaysin, methoxymaysin, and chlorogenic acid. The effect of a1 shows gene action for lowered maysin and significant epistatic action with p1. The dominant functional allele A1 causes anthocyanin pigments in aleurone, plant, and pericarp tissues; the recessive a1 allele causes absence of pigment in these tissues. If silk browning and cob color are critical factors for maysin production but lack the customer’s preference, then separating red cob and browning silk, which are controlled by the P1 allele, may be difficult if not impossible. One high silk maysin sh2 sweet corn germ-plasm, shrunken Zapalote Chico, has been released. There is some field corn germplasm with p1-wwr alleles, but the amount of antibiotic flavones and their potential as a donor need further investigation.
Study on the Normal and Skewed Distribution of Isometric Grouping  [PDF]
Zhensheng Jia, WenKai Jia
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.24056
Abstract: Because of thinking only the number of numbers but not fitting function, it would be adequate to take further afield when calculating group numbers with empirical formula. We have proved the three theorems based on studying the normal distribution, and then reach the conclusion that there is a better method to do the same work. The method is simpler and more practical than empirical method and also works well with any skewed distribution.
Existence of Ordered Solutions to Quasilinear Schr?dinger Equations with General Nonlinear Term  [PDF]
Jia Wu, Gao Jia
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.64068
In this paper, the existence of a pair of ordered solutions for the following class of equations in \"\" \"\" (1) was studied. A bounded (PS) (Palais-Smale) sequence was constructed and the related variational principle was used to prove the existence of the positive solution. The existence of the ordered solutions is finally found.
Approximate Kepler’s Elliptic Orbits with the Relativistic Effects  [PDF]
Leilei Jia
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.31004

Beginning with a Lagrangian, we derived an approximate relativistic orbit equation which describes relativistic corrections to Keplerian orbits. The critical angular moment to guarantee the existence of periodic orbits is determined. An approximate relativistic Kepler’s elliptic orbit is illustrated by numerical simulation via a second-order perturbation method of averaging.

Strategic Positioning: Key Point of Business Transformation
—Revelation of Xiangeqing’s Transition

Ying Jia
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.310010
Abstract: Explicit strategic positioning is the most important factor to motivate the development of an enterprise. Based on the specific condition for an enterprise, a unique strategy could be one competitive advantage for it. Furthermore, for the enterprises who want to change their traditional operating styles, a strategy that follows up with current environment is necessary. This essay tries to discuss the importance of specific and renewable strategic positioning based on the failed transformation of Xiangeqing and provide some suggestions for the main problems.
Coordination of Supply Chain under the Revenue Sharing-Advertising Cost Sharing Contract  [PDF]
Meng Jia
Journal of Service Science and Management (JSSM) , 2017, DOI: 10.4236/jssm.2017.103024
Abstract: In this article, we study a two-echelon supply chain with a single manufacturer and a single retailer. In the case of advertising investment affecting the market demand, we use the theory of game theory, and respectively discuss the coordination of general revenue sharing contract and revenue sharing-advertising cost sharing contract. The results show that: the general revenue sharing contract cannot achieve supply chain coordination. However, revenue sharing-advertising cost sharing contract in a specific form can achieve supply chain coordination. And in the appropriate revenue sharing contract parameters, it can also achieve a win-win situation between the two sides.
