In the geophysical exploration field, sonic log (DT) and shear (DTS) are frequently used as quick affordable procedures for reservoir evaluation. Due to high acquisition costs, DTS is only accessible in a few wells within an oil/gas field. Numerous attempts have been made establish precise relationship between other petrophysical data. this study, method based on deep extreme learning machine o...
To address the problems of strong coupling and large hysteresis in temperature control a continuously stirred tank reactor (CSTR) process, an improved sparrow search algorithm (ISSA) is proposed to optimize PID parameters. The improvement aims solve population diversity reduction easy-to-fall-into local optimal solutions when traditional close global optimum. This differs from other algorithms ...

BACKGROUND How an animal moves through its environment directly impacts its survival, reproduction, and thus biological fitness. A basic measure describing how an individual (or group) travels through its environment is Day Path Length (DPL), i.e., the distance travelled in a 24-hour period. Here, we investigate the ecological determinants of baboon (Papio spp.) troop DPL and movements at local...
We apply the tree-pattern enumeration formulæ of [7], and a new extension thereof, to some recent enumerations of distributions of leaves in ordered trees [4] and in bicolored ordered trees [5], and of distributions of certain subpaths in Dyck lattice paths [22]. the bridge guard’s bucket upside-down to dry. . . fresh leaves —Issa (1818)
Acknowledgements We thank Dr. Clifton Ragsdale and Atul Mallik for helpful discussion. Abstract The organization of primary visual cortex has been heavily studied for nearly 50 years, and in the last 20 years functional imaging has provided high resolution maps of its tangential organization. Recently, however, the usefulness of maps like those of orientation and spatial frequency preference ha...
Abstract The prediction of transmission line ice cover thickness can effectively guide the scientific operation and maintenance power sector. An improved sparrow search algorithm, convolutional neural network long short-term memory fusion model is proposed in this paper. Environmental temperature, humidity, wind speed other data are firstly normalised, CNN used to both learn signature as well i...
Aiming at the problems of slow convergence and low accuracy traditional sparrow search algorithm (SSA), a multi-strategy improved (ISSA) was proposed. Firstly, golden sine introduced in location update producers to improve global optimization capability SSA. Secondly, idea individual optimality particle swarm into position investigators speed. At same time, Gaussian disturbance optimal prevent ...
Carbon trading has been deemed as the most effective mechanism to mitigate carbon emissions. However, during market operation, competition among participants will inevitably occur; hence, precise forecasting of price (CTP) become a significant element in formulation strategies. This investigation established hybrid CTP framework combining complete ensemble empirical mode decomposition with adap...
