The iterative Fourier technique (IFT) is a high efficiency method that was proposed in recent past for the synthesis of large planar thinned arrays with isotropic radiating elements. However, the selection mechanism of IFT cannot always include the most useful elements in the “turned ON” families, which make the method trap in some local minima. Therefore, in this paper, inspired by invasive we...

Multimodal optimization is used to find multiple global & local optima which is very useful in many real world optimization problems. But often evolutionary algorithms fail to locate multiple optima as required by the system. Also they fail to store those optima by themselves. So we have to use other selection scheme that can detect & store multiple optima along with evolutionary algorithms. He...

Canada thistle is the most invasive and challenging weed in grazing systems in the Upper Midwest (Doll, personal observation) and its membership on the noxious weed lists of many states demonstrates its tenacity against conventional control tactics. The resilience of this weed can be credited to its ability to effectively reproduce through both seed production/dispersal and its extensive root s...

To better regulate the speed of brushless DC motors, an improved algorithm based on original Glowworm Swarm Optimization is proposed. The proposed solves problems poor robustness, slow convergence, and low accuracy exhibited by traditional PID controllers. When selecting glowworm neighborhood set, optimization scheme growth competition behavior weeds applied to a single prevent falling into loc...

During the past decade, as the issue of plant invasion gained recognition in the public domain, both ecologists and weed scientists voluntarily or by mandate moved to provide their expertise to the management of invasive plants on public lands. Diverse views of nature carried to the table by ecologists and weed scientists have resulted in different priorities and opinions on management strategi...

Oxalis pes-caprae f. pleniflora (Lowe) Sunding (Oxalidaceae), a naturalized invasive alien is recorded for the first time from Turkey. It has staminodes and double petals as different properties from Oxalis pes-caprae L. Sympatric variations occured in the species populations could be the result of an accumulation of mutations or genome rearrangement. Invasive alien weed Oxalis pes-caprae and i...

Ten insect species were introduced to control five weeds on the island of Mauritius from 1914 to1982. Eight of these (80%) became established. The biocontrol programs against Opuntia vulgaris, O. tuna and Cordia curassavica were completely successful, with all three target plants now not considered as weeds, and requiring no management other than the ongoing, self-sustaining biological control....
