IF <logical expression> THEN <statement>.. ELSEIF <logical expression> THEN <statement>.. ELSE <statement>.. CIF . ... ELSEIFs when present must precede any corresponding ELSE. ... When the IF or ELSEIF condition has the value .TRUE., the statements following are executed and control is transferred to the statement following the CIF. ... When the IF and all ELSEIF clauses have a value which is .FALSE., control is passed to the statement following the corresponding ELSE or CIF. ...

... Aromatic dust emission features and emission lines from molecular and atomic hydrogen are detected but they are not particularly strong. The dominant spectral features are emission lines from moderately ionized species of argon, neon, and sulfur, which are used to determine the physical conditions in the ionized gas. The ionized gas excitation shows strong variations on parsec scales, some of which can plausibly be associated with individual hot stars. ... ADS Citation Query . ...

In this method the fields outside and inside a particle are represented by expansions in term of proper basis functions (practically always the vector spherical harmonics). Since the particle surface does not coincide with the coordinate surface, it is impossible to satisfy the boundary conditions exactly, and the expansions are limited by a finite number of terms, and the boundary conditions are considered in a finite set of points (matching points). ...

Next: The Newton--Raphson Method. Up: Fitting of Data Previous: Fitting of Data . ... In a linear problem, if the errors on the observations have a gaussian distribution, the ``Maximum Likelihood Principle'' gives you the ``best estimate'' of the parameters as the solution of the so-called ``Least Squares Minimization'' that follows: . ... A certain number of numerical methods have been developed to solve the non--linear least squares problem, four have so far been implemented in MIDAS. ...

TYPES Trees are represented by two types: entree (enumerated tree) and bitree (bit tree). ... Also, it's possible to match patterns: tree <* treequery treequery >* tree The last two operations return TRUE if the node matches the treequery pattern. ... Example of how to add a node: select entree_next(tid) from dmoz where tid <* '1.2.3.*.0' order by tid desc limit 1; INDICES Type tree supports two types of indices: B-Tree - accelerates operations: <,>,<=,>= and =. ...

... In this work we present Evolution Strategies (ES) as an efficient method to approximate the initial conditions of the main interacting group of three galaxies in M81. ... In this first attempt we use nonself-gravitating simulations to approximate the initial conditions; even with that restriction our method reproduces the density distribution of the three galaxies with great precision. ... Parameters to produce the simulation in Figure 1 Index 1 is for M81, 2 for M82 and 3 for NGC3077 5. ...
