Mass trapping of Spodoptera frugiperda (Smith) in Central America required a high performance lure with consistent capture rates.S.frugiperda lures from North America and England gave erratic capture rates under field conditions.A reinvestigation of four acetate attractants (Z9-14Ac, Z11-16Ac, Z7-12Ac and Z9-12Ac) for S.frugiperda present in Costa
Modern software applications are commonly built by leveraging pre-fabricated modules, e.g.application programming interfaces (APIs), which are essential to implement the desired functionalities of software applications, helping reduce the overall development here costs and time.When APIs deal with security-related functionality, it is critical to e
In the working process of Double-Fed Wind Turbines (DFWT), it is very important to monitor and predict the temperature of the high-speed output shaft of the gearbox timely and effectively.Support vector machine has more advantages in the temperature prediction of click here wind turbines.Least squares support vector machine is suitable for online p
