Novel fuzzy logic controllers with self-tuning capability
Two controllers which extend the PD+I fuzzy logic controller to deal with the plant having time varying nonlinear dynamics are proposed. The adaptation ability of the first self tuning PD+I fuzzy logic controller (STPD+I_31) is achieved by adjusting the output scaling factor automatically thereby contributing to significant improvement in performance. Second controller (STPD+I_9) is the simplified version of STPD+I_31 which is designed under the imposed constraint that allows only minimum number of rules in the rule bases. The proposed controllers are compared with two classical nonlinear controllers: the pole placement self tuning PID controller and sliding mode controller. All the controllers are applied to the two-links revolute robot for the tracking control. The tracking performance of STPD+I_31 and STPD+I_9 are much better than the pole placement self tuning PID controller during high speed motions while the performance are comparable at low and medium speed. In addition, STPD+I_31 and STPD+I_9 outperform sliding mode controller using same method of comparison study
Measurements of K S 0 - K L 0 asymmetries in the decays Λ c + → p K L , S 0 , p K L , S 0 π + π − and p K L , S 0 π 0
Abstract Using e + e − annihilation data sets corresponding to an integrated luminosity of 4.5 fb −1, collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, we report the first measurements of the absolute branching fractions B Λ c + → p K L 0 = (1.67 ± 0.06 ± 0.04)%, B Λ c + → p K L 0 π + π − = (1.69 ± 0.10 ± 0.05)%, and B Λ c + → p K L 0 π 0 = (2.02 ± 0.13 ± 0.05)%, where the first uncertainties are statistical and the second systematic. Combining with the known branching fractions of Λ c + → p K S 0 , Λ c + → p K S 0 π + π − , and Λ c + → p K S 0 π 0 , we present the first measurements of the K S 0 - K L 0 asymmetries R Λ c + K S , L 0 X = B Λ c + → K S 0 X − B Λ c + → K L 0 X B Λ c + → K S 0 X + B Λ c + → K L 0 X in charmed baryon decays: R Λ c + p K S , L 0 = − 0.025 ± 0.031 , R Λ c + p K S , L 0 π + π − = − 0.027 ± 0.048 and R Λ c + p K S , L 0 π 0 = − 0.015 ± 0.046 . No significant asymmetries with statistical significance are observed
The relationship between the exercise of political power and language during the cultural revolution in Inner Mongolia - 1967-1969
This is an analysis of the relationship between language contained in political documents and the exercise of power and authority from the Cultural Revolution in the Inner Mongolian Autonomous Region of the People's Republic of China from 1967 to 1969. It is based on analytic methods found in the works of Foucault, Bourdieu, Gramsci and others. The material analysed falls into four periods. The
first phase in 1967 saw the initial impact of the CR manifesting itself locally by causing conflict between two key entities in the IMAR - the army and student rebellion groups. The response by the Centre to this was the conduct of dialogues with the local groups, resulting in the issuing of a key document, the '13th April Decision,' to 'resolve' the local problems and impose hegemony from the Centre, through promoting standardised narratives and a specific ideology - CR Maoism. The -second phase from 1967 to 1968 saw the implementation of this strategy through the attack on the local leader, Ulanfu. During this period the discourse to 'handle' the region was articulated promoting a narrative and ideology from the Centre in Beijing of power based on class, excluding any assertions of the primacy of ethnicity and nationality locally. The third phase from 1968 to 1969 saw the promotion by the Centre of the newly installed leader, Teng Haiqing, using this new discourse. In this period, a local enemy - the Inner Mongolian People's Party - was gradually articulated. The final phase in 1969 saw the social turmoil and violence caused by the purge of those claimed to be members of this party, and the withdrawal of support from the Centre for Teng Haiqing, resulting in his use of a self-critical language, the creation of an adapted narrative and ideology, conveyed through a new discourse in which the key issues of class and ethnicity/nationality were approached in different ways.
The focus of this thesis is the signification of power in language and discourse through this period, and the techniques by which to describe and understand this

Inhibition of 2-P-Mercaptophenyl-1,4-Naphthoquinone on Human Platelet Function
As widely assumed, platelets and coagulation system heavily influence the pathogenesis and progression of cardiovascular diseases. Some 1,4- naphthoquinone derivatives, such as vitamin K-3, have been reported to increase the synthesis of coagulation proteins. In this study, we examine how 2-p- mercaptophenyl -1,4-naphthoquinone (NTP), a newly synthesized 1,4 -naphthoquinone derivative, affects the platelet function in humans. A tapered parallel plate chamber which provided a range of shear stress covering the entire physiological range in human circulation is used to assess platelet adhesiveness on fibrinogen coated-surface. In addition, platelet aggregation and thromboxane B-2 (TXB2) production by inducers are evaluated by the turbidimetric method and enzyme immunoassay kit, respectively. Moreover, platelets [Ca2+](i) are measured using a dual- wavelength fluorescence spectrophotometer. Analysis results indicate that 1) NTP decreases the percentages of attached platelets at the locations in various shear stresses and the levels of platelet adhesiveness, denoted as the slope; 2) NTP can inhibit the platelet aggregation by ADP (2 mu M) and collagen (25 mu g/ml), and the IC50 are: 0.32 and 26.83 mu g /ml, respectively; and 3) NTP markedly inhibits TXB2 formation and platelet [Ca 2+](i) elevation caused by ADP and collagen. Therefore, we conclude that NTP may inhibit platelet adhesiveness on fibrinogen coated-surface, aggregability, [Ca2(+)](i), and thromboxane production, and that it may be used as an antiplatelet agent
Combinatorial and spectral aspects of nearest neighbor graphs in doubling dimensional and nearly-Euclidean spaces
AbstractMiller, Teng, Thurston, and Vavasis proved a geometric separator theorem which implies that the k-nearest neighbor graph (k-NNG) of every set of n points in Rd has a balanced vertex separator of size O(n1−1/dk1/d). Spielman and Teng then proved that the Fiedler value — the second smallest eigenvalue of the Laplacian matrix — of the k-NNG of any n points in Rd is O((k/n)2/d). In this paper, we extend these two results to nearest neighbor graphs in a metric space with a finite doubling dimension and in a metric space that is nearly-Euclidean. We prove that for every l>0, if (X,dist) forms a metric space with doubling dimension γ, then the k-NNG of every set P of n points in X has a vertex separator of size O(k2l(64l+8)2γlog2LSlogn+nl), where L and S are, respectively, the maximum and minimum distances between any two points in P. We show how to use the singular value decomposition method to approximate a k-NNG in a nearly-Euclidean space by a Euclidean k-NNG. This approximation enables us to obtain an upper bound on the Fiedler value of k-NNGs in a nearly-Euclidean space
