This proposal is presented in accordance with Resolution Conf. 9.24 with particular emphasis on the following: (1) The biological criteria (cf. Annex 1, Res. Conf. 9.24) for Appendix 1 stocks are not met for this stock. (2) Precautionary measures (cf. Annex 4, Res. Conf. 9.24) are fulfilled through national conservation and management measures and establishment of a trade control system based o...

Several motion control techniques rely on shape control rather than actuator command. A shape controller speciies the desired shape of the object, but not its position and orientation. The actual position and orientation result from interaction with the surrounding world. We propose to use a bank of wavelet networks, together with local optimization algorithms, as a tunable deformation controll...

The sequence of the mitochondrial control region was determined in all 10 extant species commonly assigned to the suborder Mysticeti (baleen or whalebone whales) and to two odontocete (toothed whale) species (the sperm and the pygmy sperm whale). In the mysticetes, both the length and the sequence of the control region were very similar, with differences occurring primarily in the first approxi...

In view of the shortcomings whale optimization algorithm (WOA), such as slow convergence speed, low accuracy, and easy to fall into local optimum, an improved (IWOA) is proposed. First, standard WOA from three aspects initial population, factor, mutation operation. At same time, Gaussian introduced. Then nonfixed penalty function method used transform constrained problem unconstrained problem. ...

With the aim of improving rapidity and accuracy quadrotor UAV positional trajectory tracking, this paper proposes a fuzzy automatic disturbance rejection control based on improved whale optimization algorithm (IWOA-Fuzzy-ADRC). (1) To address problems low slow convergence traditional algorithm, combination logistic chaos mapping skew tent is applied to improve diversity initial population. (2) ...

The non-orthogonal multiple access (NOMA) scheme has proven to be a potential candidate enhance spectral potency and massive connectivity for 5G wireless networks. To achieve effective system performance, user grouping, power control, decoding order are considered fundamental factors. In this regard, joint combinatorial problem consisting of grouping control is considered, obtain high spectral-...

High penetration of renewable energy sources into isolated microgrids (µGs) is considered a critical challenge, as µGs’ operation at low inertia results in frequency stability problems. To solve this virtual control based on an storage system applied to enhance the and damping properties µG. On other hand, utilization phase-locked loop (PLL) indispensable for measuring frequency; however, its d...
