Alkaline phosphatase activity (APA) and dissolved phosphorus were monitored during the batch cultures of two bone microalgae. Results indicate that variation of APA was in the shape of 'S' curve. Different specs of dissolved phaphorus had different effects on APA. The concentrations of dis solved inorganic phosphorus (DIP) and and molecular dissolved organic phosphorus (SDOP) had a sig nificant effect on APA, while the concentration of large molecular dissolved organic phosphorus (LDOP) had a little effect on APA., and the increase of APA could accelerate the decomposing of LDOP in the medium. Results also show that algae species and abundance had why a little effect on APA.

Receivers for new generation Global Navigation Satellite System （GNSS） signals have to adjust internal parameters adaptively based on the detection of users’ situations to keep the robust and good navigation quality. Thus, the pre-correlation time and the loop noise bandwidth of the Adaptive Tracking Loops （ATLs） should be self-adjusted. In the previous research, Fuzzy Inference System （fis） based Carrier-to-Noise Ratio （CNR） estimator is used to adjust precorrelation time according to the signal strength. In this paper, a novel method of Adaptive kalman Filter （AkF） in order to adjust noise bandwidth of ATLs automatically will be introduced and analyzed. Simulation results show that the novel robust tracking algorithms can give better tracking results than traditional tracking loops when the situation is stable, and can adjust self-parameters quickly to keep robust tracking quality when the situation is changeable.

Software operational profile （SOP） is used in software reliability prediction, software quality assessment, performance analysis of software, test case allocation, determination of ＂when to stop testing,＂ etc. Due to the limited data resources and large efforts required to collect and convert the gathered data into point estimates, reluctance is observed by the software professionals to develop the SOP. A framework is proposed to develop SOP using fuzzy logic, which requires usage data in the form of linguistics. The resulting profile is named fuzzy software operational profile （FSOP）. Based on this work, this paper proposes a generalized approach for the allocation of test cases, in which occurrence probability of operations obtained from FSOP are combined with the criticality of the operations using fuzzy inference system （fis）. Traditional methods for the allocation of test cases do not consider the application in which software operates. This is intuitively incorrect. To solve this problem, allocation of test cases with respect to software application using the fis model is also proposed in this paper.

This paper is to identify and classify the various types of shunt and line faults in transmission line. The faults may be an insulation failure, lightning or accidental faulty operation. In a transmission line protection important factor is identifying a fault because if any error occurs in finding fault may leads to abnormal operation of the protection system. So either a disturbance or steady state variation is called power quality variation. The proposed test system is modeled based on the neural network and fuzzy algorithm. The online symmetrical components are extracted by this above algorithm. The fuzzy is used to separate the oscillating components and average components. Here input for the fuzzy is trained by using neural network. It is based on current samples and very effective in fault classifier using rule base. This method is very much suitable for online implementation.

Polymorphic simple sequence repeat （SSR） markers were isolated and used to genetic analysis of Coptis Omeiensis, a critically endangered perennial herbaceous medicinal plant with a limited distribution in Mount Emei in China. Intrapopulation genetic diversity, population structure and gene flow in the six remnant populations and a transplanted population by five fluorescent SSR markers. The population structure analysis provided convincing evidence for the presence of two independent populations in Coptis Omeiensis implemented in STRUCTURE program, which confirmed by the chloroplast data. A relatively high degree of genetic diversity （A = 4.7;HO = 0.397 and HE = 0.588） were detected in the remnant population. A low gene flow Nm = 0.8812 and recent declined population size in four of the six remnant populations were observed by BOTTLENECk program. Significant genetic differentiations among populations were found based on Wright?s FST and AMOVA analysis. High fis was calculated in four of the six populations and inbreeding depression was observed in the wild. A clear riparian-mountain landscape structure was also discussed in the present study. Both in situ and ex situ conservation management for the remnant populations of Coptis Omeiensis are urgently needed to rescue the remaining genetic diversity.

利用微卫星技术对中国对虾人工选育群体第1代和第6代群体的遗传多样性进行了分析。对10个微卫星位点进行了扩增,共产生74个等位基因,每个位点产生的等位基因数从3到13不等。在两个群体中,所观察到的等位基因数都比有效等位基因数多。多态信息含量PIC值0.5567～0.8877,说明这10个微卫星位点在中国对虾中具有较高的信息含量。两个群体的平均杂合度分别为0.6400(CP1)、0.6300(CP6),并通过计算基因型的P值,确定了对Hardy Weinberg平衡的偏离情况。对fis值的计算表明两个群体内共有5个微卫星位点存在杂合度观察值过剩的现象。两个群体的Shannon多样性指数分别为1.6830、1.7382,整个选育群体(两个群体作为一个群体)的遗传多样性指数为1.7742。从遗传多样性所占的比例来看,96.415%的遗传变异是来自群体内,只有3.585%的遗传变异是来自群体间。两个群体间的相似性系数高达0.9187,彼此间的遗传距离仅为0.0848,体现出人工选育群体的遗传分化程度较低。结果均说明第6代群体还有较大的选育潜力,可以继续保持遗传效应,最终保证选种育种工作的成功。
