demographic parameters of the ladybeetle, serangium montazerii fursch feeding on citrus whitefly, dialeurodes citri ashmead were determined on two host plants, page tangerine and thompson navel orange. this study was carried out under laboratory conditions (25 ± 1 °c and rh of 60 ± 5% and a photoperiod of 16: 8 h (l: d). total pre-adult periods of the lady beetle were 20.84 ± 0.302, 19.27 ± 0.2...

Time-Delay Interferometry (TDI) is the data processing technique that cancels large laser phase fluctuations affecting heterodyne Doppler measurements made by unequal-arm space-based gravitational wave interferometers. The space of all TDI combinations was first derived under simplifying assumption a stationary array, for which three time-delay operators commute. In this model, any element can ...

We argue that the current, predominantly task-oriented, approaz~hes to modularizing text • generation, while plausible and useful conceptually, set up spurious conceptual and operational constraints. We propose a data-driven approach to modularization and illustrate how it eliminates • •the previously ubiquitous constraints on combination of evidence across modules and on • control. We also bri...

in order to investigate the effect of temperature and time of blanching process on the generation and extraction of reducing sugars and kinetics of color changes during blanching, the potato strips packaged in the polyethylene (hdpe with 10 micron thickness) film or without polyethylene packaging, were immersed in distilled water at temperature range of 50, 60, 70, 80 and 90 ºc for 120 minutes....

The analytic center cutting plane method (ACCPM) is one of successful methods to solve nondifferentiable optimization problems. In this paper ACCPM is used for the first time in the vehicle routing problem with time windows (VRPTW) to accelerate lagrangian relaxation procedure for the problem. At first the basic cutting plane algorithm and its relationship with column generation method is clari...

ower system loads are sensitive to frequency and following system frequency changes the aggregate load change follows the frequency deviation. When a generating unit is tripped or additional load is added to the system, the power mismatch is initially compensated by an extraction of the kinetic energy from the system inertial storage (the spinning masses) that causes a system frequency drop. As...
