Copyright @ 2004 IEEEA method is presented for finding the optimum fixed LC compensator for power factor correction of nonlinear loads where both source voltage and load current harmonics are present. The LC combination is selected because pure capacitive capacitors alone would not sufficiently correct the power factor. Optimization minimizes the transmission loss, maximizes the power factor, and maximizes the efficiency. The performance of the obtained compensator is discussed by means of numerical examples

Copyright @ 2004 IEEEThis paper presents a method employing the penalty function search algorithm to determine the LC compensator value for the optimal power factor correction in nonsinusoidal systems. The objective of the proposed method is to minimize the transmission loss while the power factor and efficiency are taken as constraints and utilized in order to solve the multiobjective optimization problem by transforming it into a single objective one. Examples show that the load nonlinearity can have a significant impact on optimal compensator sizes

Natural history notes. Tukunha pinimauna sp. nov. is registered in Terra Firma forest (Fig. 18) in the endemic areas of Guiana and Tapajós. All adult specimens were collected using light traps and a single nymph was found in shrubby vegetation on leaves of Triplophyllum discksonioides (Tectariaceae)(Fig. 17B). It is likely that adults inhabit the upper strata of the forest (understory and canopy), as observed in most phaneropterine species in Central Amazonia.Published as part of Mendes, Diego Matheus De Mello & Rafael, José Albertino, 2021, Two new and rare genera of angle-winged katydids (Orthoptera: Tettigoniidae Phaneropterinae: Microcentrini) from the Brazilian Amazon Rainforest, pp. 553-572 in Zootaxa 4999 (6) on pages 566-570, DOI: 10.11646/zootaxa.4999.6.

Internal or personal use of this material is permitted. However, permission to reprint/republish this material for advertising or promotional purposes or for creating new collective works for resale or redistribution must be obtained from the IEEE by writing to [email protected]. Copyright @ 2005 IEEEThe objective of this paper is to propose a new approach for designing passive LC compensators by using the penalty function method as an optimization tool. The performance of the cost-effective passive LC compensator for a constant load depends on the appropriate inductor and capacitor selection. Several design methods are reviewed and a novel design methodology is proposed in this paper. By using the proposed method, the designer can quickly find appropriate parameter values to meet the desired circuit performance. Simulated results show that an appropriate combination of the inductor and capacitor selected by the proposed method can meet the desired power-quality requirement. Different cases of design examples are shown in this paper to verify the performance of the proposed design methodology

The forest at the collecting site and in general between 1400-1600m on the north slope of Serra do Sol is tall (15-20m canopy), made up mostly of straight, narrow-trunked trees with heavy loads of epiphytic mosses. The soil, vegetation, and atmosphere were extremely humid at this elevation during the expedition, nearly constantly bathed in clouds when not actually raining. Etymology. This species is dedicated to Dr. Mario Cohn-Haft, one of the most important ornithologists and naturalists in the Amazon and a dear friend for long time, who was always patient in talking, answering questions and teaching about animals (especially birds), plants and many other topics of Amazonian biodiversity. In addition, he organized (along with other researchers) several expeditions in remote areas of the Amazon, including the Scientific Expedition of Serra do Sol. It is thanks to this effort and curiosity that many new taxa from different groups have been and are being described, including this one.Published as part of Mendes, Diego Matheus De Mello, 2022, The Little Fog Dragon-a new genus of Mountain Lichen Katydid (Orthoptera: Tettigoniidae: Phaneropterinae: Dysoniini) from the Serra do Sol, Roraima, Brazil, pp. 84-92 in Zootaxa 5182 (1) on pages 88-91, DOI: 10.11646/zootaxa.5182.1.6, http://zenodo.org/record/704287

Fastigium dorsally short, gently bilobed. Vertex trapezoidal, frontally bilobed. Thorax. Dorsal pronotal disc rugose with slight linear depression (Figs. 7 C–D). Dorsolateral and furcal sutures deeply marked (Fig. 7C). Furcal sutures connected. Meso- and metasternum laterally compressed (Fig. 7C). Mesosternum anteriorly rhomboid. Lateral lobes of mesosternum with apex rhomboid (Fig. 7E). Metasternum diamondshaped (Fig. 7E). Lateral lobes of metasternum curved with rounded apex (Fig. 7E). Wings. A pentagonal cell present between veins MP and CuA (Fig. 8). Vein CuA with five bifid branches with bifurcations at apex (Fig. 8). Left stridulatory with basal teeth short, gradually increasing in length towards median region (Fig. 9A). Median teeth slender, close to each other. Left stridulatory file with 78 teeth, length of 3.2 mm and greatest width of the vein of 0.4 mm (Fig. 9A). Left stridulatory sinuous, with convex base, median region nearly straight, distally concave (Fig. 9B). Basal and distal teeth short, widened. Median teeth slender, close to each other (Fig. 9A).
