EDGE ORDERED TURAN PROBLEMS
No full textWe introduce the Turan problem for edge ordered graphs. We call a simple graph edge ordered, if its edges are linearly ordered. An isomorphism between edge ordered graphs must respect the edge order. A subgraph of an edge ordered graph is itself an edge ordered graph with the induced edge order. We say that an edge ordered graph G avoids another edge ordered graph H, if no subgraph of G is isomorphic to H. The Turan number ex(<)'(n, H) of a family H of edge ordered graphs is the maximum number of edges in an edge ordered graph on n vertices that avoids all elements of H.We examine this parameter in general and also for several singleton families of edge orders of certain small specific graphs, like star forests, short paths and the cycle of length four.DC

FRR 768, 5, 93–153 mm SL; Turkey: Kahramanmaraş Prov.: Ceyhan River; Menzelet Reservoir; Geçit Stream on road from Kahramanmaraş to Andırın; D. Turan, Z. Bostancı & Ş. G. Kırankaya, June 2005. - FRR 769, 5, 197 – 218 mm SL; Turkey, Adana Prov.: Seyhan Reservoir; D. Turan & Z. Bostancı, 20 June 2005. Diagnosis. Squalius kottelati is a member of the S. lepidus group, diagnosed by an elongate and pointed head with projecting lower jaw and the posteriorly expanded lateral portions of the parietals (Bogutskaya 1994). Squalius kottelati is distinguished from the other species of the genus Squalius in Turkey and adjacent basins by having a conspicuous broad, dark stripe on the upper part of the flank from the head to the end of the caudal peduncle (vs. absent or very faintly marked, except in S. lepidus). It differs from S. lepidus by having a longer head (28.3–30.9, vs. 25.3–27.3 % SL), fewer scales in lateral line (total 45–47, vs. 48–49) and fewer gill rakers on the outer side of first gill arch (9–10, vs. 11–13). It also differs from S. anatolicus by having more scales in lateral line (45–47, mode 46, vs. 43–45, mode 44); a longer caudal fin (length of upper lobe: 20.3–22.5, vs. 15.8 –19.0 % SL). Other characters useful for identification are: snout pointed in males, slightly rounded in females; anal fin with 8–9 ½ branched rays, its outer margin straight or slightly convex, with light-brown pigments on rays. Description. General appearance is shown in Figure 1; morphometric and meristic data are given in Tables 1 and 2. Body slender, slightly compressed laterally, depth at dorsal-fin origin 20.7–25.1 % SL. Dorsal profile slightly convex, with a hump at nape; dorsal profile more convex than ventral profile. Head long, slender, its length 1.2–1.4 times body depth; dorsal profile straight on interorbital area, concave on snout. Snout short, its length 26.8–29.8 % HL, slender, narrower, tip slightly pointed. Mouth slightly superior, long, narrow, angle of gape reaching vertical through anterior margin of eye. Lower jaw markedly longer than upper jaw, especially in specimens larger than 180 mm SL. Eyes large, diameter 15.8–19.5 % HL. Interorbital area narrow, its width 27.9–31.9 % HL. Maximum known size 203 mm SL. Dorsal fin with 3 simple and 8 ½ branched rays, approximately equal to pectoral-fin length, distal margin straight, origin markedly behind vertical through pelvic-fin origin. Pectoral-fin distal margin straight, with 16–17 branched rays. Pelvic-fin distal margin straight, with 1 simple and 8 branched rays. Anal fin with 3 simple and 8–9 ½ branched rays; distal margin straight or slightly convex. Caudal fin long, length of upper lobe 20.3–22.5 % SL, markedly forked, lobe tips pointed. Lateral line with 45 (3), 46 (8) or 47 (3) scales; 7 (9) or 8 (5) scales rows between lateral line and dorsal-fin origin; 3 (4) or 4 (10) scales between lateral line and anal-fin origin. Gill rakers 3 + 6–7 = 9–10 on outer side of first gill arch. Vertebrae 23 + 19 = 42 (6) or 24 + 19 = 43 (8). Pharyngeal teeth 5.2 – 2.5, markedly hooked, serrated. The snout of males is more pointed than that of females. Coloration. Formalin-preserved adults and juveniles dorsally dark grey, grayish on flank, whitish on belly; a conspicuous broad, dark stripe on upper part of flank from head to end of caudal peduncle. Caudal fin dark grey. Dorsal, pectoral, pelvic and anal fins yellowish. Light-brown pigments on dorsal and anal-fin rays. Scales with a dark spot on scale pocket, especially in specimens larger than 180 mm SL; faintly marked to distinct dark edge along posterior margin; usually with one or two rows of large black pigments on posterior margin of scales of flank and dorsum. Etymology. The species is named for Maurice Kottelat, fish taxonomist, in appreciation for his contributions to knowledge of the fish faunas of Europe and Asia. Distribution. Squalius kottelati is presently known only from Tahtalıköprü reservoir in the drainage of Orontes River, drainages of Ceyhan and Seyhan rivers (Fig. 2).

Hybrid control of a 3-d structure by using semi-active dampers
No full textA base isolated three storey 3-D building is semi-actively controlled not to exceed the maximum allowable base displacement. Large displacements are likely to cause failure in the isolation system, and hence, failure in the superstructure is expected. If a base isolated structure is positioned next to a very long fault line, such as the North Anatolian Fault, the structure will mostly undergo far field type excitations. Near field effects will be seen less occasionally, but design considerations should be made to account for both types of excitations. In case of nearby seismic action, the isolated building should be smart enough to modify its isolation impedance to resist against large ground displacement and velocities. For this study, an isolated three storey building model together with four dampers, which are all placed at the base level, is considered. The dampers have controllable orifices (damping coefficients) and the magnitudes of these damping coefficients are assigned by using a linear quadratic regulator (LQR). During an earthquake excitation, the storey displacements and velocities are used as feedback in the calculation of the optimal control force that is producible by viscous dampers, at each time step. This force, however, is applied only at times when critical displacements and/or velocities occur. The performance of the set of controllers is presented via time simulations of the system for three recorded earthquakes. In addition, these records are time shifted five folds to see the effect of near field action. The results indicate that the control effectively reduces the maximum displacements of the isolation system, while maintaining a reasonable isolation to the superstructure
