A frequency averaging framework for the solution of complex dynamic systems
No full textA frequency averaging framework is proposed for the solution of complex linear dynamic systems. It is remarkable that, while the mid-frequency region is usually very challenging, a smooth transition from low- through mid- and high-frequency ranges is possible and all ranges can now be considered in a single framework. An interpretation of the frequency averaging in the time domain is presented and it is explained that the average may be evaluated very efficiently in terms of system solutions

TYPES. — Annam. massif de Cô Inh près Nhatrang [= Vietnam. Khanh Hoa, Mt. near Nha Trang], 17.IX.1922, Poilane 4606 (lecto-, P [P00721608]!, designated here; isolecto-, K [K001351309, K001351310]!; P [P00721609, P00721610]!; SING!). REMAINING ORIGINAL MATERIAL. — Annam. Núi Han Heo près de Nhatrang [= Vietnam. Khanh Hoa, Mt.

NOTES Lecomte (1930: 948) cited Poilane material from “ Annam: province de Nhatrang, Cô-inh, Henkéo, alt. 700 m. ” as the original material but did not give collection numbers. We found two collections with matching characteristics: Poilane 4873 from Han Heo, Nhatrang, and Poilane 4606 from Cô Inh, Nhatrang, with specimens at K, NY, P, SING and VNM. The selected lectotype (P00721608), belonging to the gathering Poilane 4606, includes a wood sample and a typed description of the wood that matches closely the protologue.Published as part of Meeprom, Nattanon, Utteridge, Timothy, Culham, Alastair & Puglisi, Carmen, 2022, Lectotypification of Indochinese Ebenaceae published by P.

Zero and root loci of disturbed spring-mass systems
No full textModels consisting of chains of particles that are coupled to their neighbours appear in many applications in physics or engineering, such as in the study of dynamics of mono-atomic and multi-atomic lattices, the resonances of crystals with impurities and the response of damaged bladed discs. Analytical properties of the dynamic responses of such disturbed chains of identical springs and masses are presented, including when damping is present. Several remarkable properties in the location of the resonances (poles) and anti-resonances (zeros) of the displacements in the frequency domain are presented and proved. In particular, it is shown that there exists an elliptical region in the frequency–disturbance magnitude plane from which zeros are excluded and the discrete values of the frequency and disturbance at which double poles occur are identified. A particular focus is on a local disturbance, such as when a spring or damper is modified at or between the first and last masses. It is demonstrated how, notably through normalization, the techniques and results of the paper apply to a broad category of more complex systems in physics, chemistry and engineering

(sommet) [= Vietnam. Khanh Hoa, the summit of Mt. Hon Ba, 1500 m alt.], 28-31.VIII.1918, Chevalier 38854 (lecto-, P, first-step designated byNguyen [1996: 66]; P [P00721602], Fig. 2, second-step designated here; isolecto-, E [E00934303]!; K [K000342277]!; P [P00721603, P00721604]!). NOTES Lecomte (1930: 948) only cited a Chevalier collection from “ Annam: S. massif de Hon-ba, alt. 1200–1500 m., en forêt” as the original material. Nguyen (1996: 66) cited Chevalier s.n. (P) as the holotype, effectively making a first-step lectotypification. We have located five sheets of Chevalier 38854 at E, K and P, collected from the cited locality, and annotated by Chevalier as “ Diospyros fleuryana A.Chev. ”. Three of them, K000342277, P00721602 andP00721604 are also annotated as “type” in Chevalier’s handwriting.The specimen P00721602, being in the best conditions, is chosen here as the lectotype.Published as part of Meeprom, Nattanon, Utteridge, Timothy, Culham, Alastair & Puglisi, Carmen, 2022, Lectotypification of Indochinese Ebenaceae published by P.
