Particle field holography data reduction by Fourier transform analysis

The size distribution of a particle field hologram is obtained with a Fourier transformation of the Fraunhofer diffraction pattern of the reconstructed hologram. Off-axis absorption holograms of particle fields with known characteristics were obtained and analyzed with a commercially available instrument. The mean particle size of the reconstructed hologram was measured with an error of + or - 5 percent, while the distribution broadening was estimated within + or - 15 percent. Small sections of a pulsed laser hologram of a synthetic fuel spray were analyzed with this method thus yielding a spatially resolved size distribution. The method yields fast and accurate automated analysis of particle field holograms

Light Horses In Iowa

From the heart of the Cornbelt comes the appearance of an improving horse industry. At one time considered the most important property owned by man, the horse has gone through a stage of decreased popularity and is once again making a bid for proper recognition. According to the 1944 census, Iowa has the greatest number of horses of anyone state, that is, 612,000 head. Texas follows up closely in second place with 588,000. Minnesota, third with 539,000; Missouri, fourth with 519,000, and Wisconsin with 451,000 horses stands fifth in rank

Pengembangan Lks Untuk Metode Penemuan Terbimbing Pada Pembelajaran Matematika Kelas VIII Di SMP Negeri 18 Palembang

The aim of this research are : (1) Producing the student worksheet for valid and practical guidance find method in math learning in the eighth class student in SMP Negeri 18 Palembang. (2) To know potential effect of the using student worksheet for guidance finder method to ability the eight class in SMP Negeri 18 Palembang. The research is developed learning practice plan, the student worksheet and the ability student test.This research use the development research method, and it contains analysis, design, evaluation and revision. The collecting data were used by observation and test. Observation use to analysis student activity along teaching learning process and the test use to analysis student ability. Subjects in this research are 40 students in the eight class in SMP Negeri 18 Palembang.The conclusion are: (1). the student worksheet are developed in this research is valid, practical and have potency effect for the student ability in the eighth class student in SMP Negeri 18 Palembang. (2). Prototype of the student worksheet is valid and practical. Valid were shown by validation evaluation that all validation result good base on content and construct and language. Practical were shown by every student can using the student worksheet good. (3) the student worksheet have potency effect to student ability. It were shown b the ability test result in good student ability level

Near IR diffraction-limited integral-field SINFONI spectroscopy of the Circinus galaxy

Using the adaptive optics assisted near infrared integral field spectrometer SINFONI on the VLT, we have obtained observations of the Circinus galaxy on parsec scales. The morphologies of the H_2(1-0)S(1) 2.12um and Br_gamma 2.17um emission lines are only slightly different, but their velocity maps are similar and show a gradient along the major axis of the galaxy, consistent with rotation.Since V_rot/sigma is approximately 1 suggests that random motions are also important, it is likely that the lines arise in a rotating spheroid or thickened disk around the AGN. Comparing the Br_gamma flux to the stellar continuum indicates that the star formation in this region began almost 10^8 yr ago. We also detect the [SiVI] 1.96um,[AlIX] 2.04um and [CaVIII] 2.32um coronal lines. In all cases we observe a broad blue wing, indicating the presence of two or more components in the coronal line region. A correlation between the ionisation potential and the asymmetry of the profiles was found for these high excitation species.Comment: 6 pages, 5 figures, Submitted to the Proceedings of the IFS Workshop, Jul 4-8 2005, Durham, Englan
