So far, there is no computer algorithm to draw unstable invariant closed curves on a Poincare map representing quasi-periodic orbits. Recently, we developed a new algorithm to draw unstable invariant closed curves by using the bisection method. The results of this new algorithm are compared with the previously obtained averaging method results. Several new results are found, which could not be clarified by the averaging method. <\/jats:p>","DOI":"10.1142\/s0218127412300224","type":"journal-article","created":{"date-parts":[[2012,4,24]],"date-time":"2012-04-24T01:04:26Z","timestamp":1335229466000},"page":"1230022","source":"Crossref","is-referenced-by-count":16,"title":["BIFURCATION OF QUASI-PERIODIC OSCILLATIONS IN MUTUALLY COUPLED HARD-TYPE OSCILLATORS: DEMONSTRATION OF UNSTABLE QUASI-PERIODIC ORBITS"],"prefix":"10.1142","volume":"22","author":[{"given":"KYOHEI","family":"KAMIYAMA","sequence":"first","affiliation":[{"name":"Department of Electronics and Bioinformatics, Meiji University, 1-1-1 Higashi-Mita, Tama-ku, Kawasaki-shi, Kanagawa, 214-8571, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MOTOMASA","family":"KOMURO","sequence":"additional","affiliation":[{"name":"Department of Occupational Therapy, Teikyo University of Science, 2525 Yatsusawa, Uenohara-shi, Yamanashi, 409-0193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TETSURO","family":"ENDO","sequence":"additional","affiliation":[{"name":"Department of Electronics and Bioinformatics, Meiji University, 1-1-1 Higashi-Mita, Tama-ku, Kawasaki-shi, Kanagawa, 214-8571, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,7,16]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/TCS.1978.1084477"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1109\/TCS.1976.1084183"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1109\/TCS.1978.1084380"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1109\/TCS.1980.1084816"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1109\/TCS.1984.1085495"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1016\/0167-2789(89)90253-4"},{"key":"rf8","first-page":"1788","volume":"77","author":"Papy O.","journal-title":"IEICE Trans.
