A Stars Case Study in Process Deenition
نویسنده
چکیده
Explicit, formal deenitions of software processes are needed for process understanding, communication, analysis, execution guidance, and improvement support. We conducted a case study which involved the creation of formal process deenitions using Abstraction Hierarchy Diagrams, IDEF0, MVP-L, and APPL/A. This paper describes the study, presents the lessons learned about process deenition in general, and compares the notations used. We discovered that diierent notations were appropriate depending on the goals of the process deenition eeort.

متن کاملSubstellar Companions to Nearby Stars from NICMOSSurveysGlenn
A coronagraphic imaging survey of 65 nearby stars was conducted using the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) on the Hubble Space Telescope by the Instrument Deenition Team. Using these guaranteed time observations we searched for very low mass stellar and substellar (extra-solar giant planet and brown dwarf) companions to young main sequence and late M dwarf stars. Nine...

The linear adiabatic pulsation-periods of Mira variable stars have been derived. Approximately 2701[1]models were calculated for M = 0.7 MΘ to 2 MΘ stars with radii from 180 RΘ to 340 RΘ and luminosities from 2800 LΘ to 10,000 LΘ. The chemical composition of all models is (X,Z) = (0.7,0.02). From the result of this study, linear relations on Luminosity-Period-Mass relationship and luminosity-pe...
متن کاملPulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I
We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...

In this study, 1200 images and catalogues of M33 spiral galaxy taken by WFCAM camera at UKIRT telescope in J, H and K bands. Cross correlation methods were employed to identify stars in overlapping regions from among images taken in different dates. Careful astrometric and photometric analysis was made to calibrate stellar positions and magnitudes using their 2MASS near infra red survey. The fi...
