Time-varying sliding mode controller(TVSMC) with fuzzy algorithm for an unmanned automatic excavator system is proposed in this paper. Proposed control system is induced from dynamics of 3-link excavator that is boom, arm and bucket. To design the proposed control system, the main structure of controller is based on sliding mode controller(SMC) with time varying sliding surface. In case of TVSM...

This experimental study looks at the problem of pathological disorders analysis from speech signals. Knowing that the vocal tract pathologies provide acoustic changes commonly called dysphonia. In particular, laryngeal pathologies have an effect on the larynx and vocal cords. When regarding to the speech production model, source-filter, the impact is even more apparent in the glottal source. Ou...

Protein A (SpA) is a component of the cell wall of Slop,lylococcus aureers. SpA is unique in that it combines with the Fc portion of immunolgobulins from many speciesi,2) and has been used in immunochemical studies3,`>. Another distinctive f ature of SpA is its potent mitogenic activity on lymphocytes from several species, including hurnans5,iO}. SpA also exerts a mitogenic activity on both T a...

Densities and viscosities of L-Threonine in water mixed aqueous solution tetrahydrofurfurylalcohol at 298.15K. On the basis these data ,the apparent molal volumes ,partial infinite dilution °, slop ,transfer volume , Gibbs free energy activation for viscous flow ΔG*1,2 B-coefficient have been calculated using Jones-Dole equation . The obtained thermodynamic properties discussed terms intermolec...

An important amount of work exists on the topic of optimal operation and control of batch distillation though it is still based on the assumption of an accurate process model being available. While this assumption is valid from a theoretical point of view, there will always remain the challenge of practical applications. Reinforcement Learning (RL) has been recognised already as a particularly ...

A Vertical Partitioning is the process of dividing the attributes of a relation. Further, a good Vertical Partitioning puts frequently accessed attributes of the relation together in a fragment. Various researchers have proposed different algorithms for Vertical Partitioning. Still, there is a scope of improvement in previous algorithms for Vertical Partitioning. In this paper a new algorithm i...

In this Letter, we propose new criteria for asymptotic stability of Lur’e systems with sector and slope restrictions. The criteria are expressed in terms of linear matrix inequality which has full block scaling matrix. By interpreting the criteria in the frequency domain using KYP lemma, the less conservativeness of the proposed analysis method is investigated. Furthermore, we analyze the dynam...

The disadvantages of the fuzzy BP learning are its low speed of error convergence and the high possibility of trapping into local minima. In this paper, a fuzzy proportional factor is added to the fuzzy BP’s iteration scheme to enhance the convergence speed. The added factor makes the proposed method more dependant on the distance of actual outputs and desired ones. Thus in contrast with the co...
