    Lettre N° 1 Le 21 mars 2006 Cher Abbas Kiarostami, Après ces quelques semaines de silence occupées en partie par la préparation scientifique de notre projet toulousain au mois de mars l’année prochaine, je reviens donc vers vous pour entamer cet entretien épistolaire que vous avez aimablement accepté d’engager avec moi à propos de la place qu’occupe l’arbre dans votre travail de cinéaste. D’ailleurs, ces premiers jours de Nowrōz qui célèbrent le nouvel an persan et qui correspondent chez nous..

    Sistem navigasi dan trajectory robot kurang efisien bila menggunakan media dari luarseperti garis atau dinding ruangan. Robot navigasi odometri menggunakan MyRIO dibuatuntuk pengujian pengendalian posisi agar lebih efektif. Alat ini menggunakan sensor rotaryencoder untuk mencacah pergerakan robot omni pada koordinat x dan y pada prosesperhitungan odometri. Penggerak robot omni menggunakan motor DC 25GA370,mikrokontroler NI MyRIO-1900 sebagai sistem antarmuka dan software LabVIEWdigunakan untuk memasukkan set point. Untuk memperoleh hasil pergerakan robot yangbaik pada sistem odometry, kendali PID diterapkan untuk mengendalikan kecepatan putarmasing-masing motor DC pada roda robot omni. Untuk menguji kinerja metode odometridalam melakukan proses kendali posisi, terdapat dua jenis pola pengujian trajectory, yaitupersegi dan segitiga siku. Dari hasil pengujian ini, diperoleh nilai kesalahan di bawah 5%

    Due to Eucalyptuspotential as a fast growing species, its utilization for afforestation and industrial and medical purposes is very important. E. maculata Hook. is an important species among the other eucalypts in respect to some chemical components production and medical utilization. Sexual and asexual propagation of this species is difficult, for this reason the trial was conducted to investigate its propagation by tissue culture, using micro mature stocks. The produced explants from the mature stocks, were placed on MS medium (Murashige and Skooge) treated by ½ nitrate and various growth regulators such as Kin (Kinetin), BAP (Benzylamino purine), IBA (Indole-3-acetic acid), 2ip (2-Isopentyladenine), TDZ (Tidiazorun) and NAA (Naphtalen Acetic Acid) at different levels of concentration. After two months, growth indexes, including shoot number, shoot height, root number, root length, bud number and greenness rate were measured and recorded. Results showed that the best shooting treatment was IBA (0.01 mgl-1), BAP (0.3 mgl-1) and 2ip (0.5 mgl-1), in which average shoot number, shoot height and greenness rate were 4.63, 2.73 cm and 3.75, respectively, whereas the best rooting treatment was NAA (0.5 mgl-1) plus IBA (0.5 mgl-1), in which root length was 0.2 cm. Finally, the micropropagated plantlets were transferred to greenhouse to pass their adaptation process
