     A data dictionary plays an important role in the life cycle of the whole information system. In this paper, is intreduced the basic method for the development of the data dictionary with the field data capture system as an example. Then a detailed analysis is made of data structural features in such dictionaries as the table attribute dictionary, the field attribute dictionary, the table field dictionary, the index information dictionary, the data constraint dictionary and the relation dictionary that can store various relationships between tables.

Our SSD-based regularization method uses a normalized SSD measure (based on a similar reasoning as in the gradient-based scheme) as the data constraint in a regularization framework.
      
Each data constraint is appropriately normalized to obtain an approximate minimum distance (of the data point to the linear flow equation) constraint instead of the conventional linear flow constraint.
      
Solving the 4-d Einstein equations as evolution in time requires solving equations of two types: the four elliptic initial data (constraint) equations, followed by the six second-order evolution equations.

The paper discussed the principle of genetic algorithm(GA), a method used to solve nonlinear optimization problems. Research results indicate that GA favours complex problems including inversion without borehole data constraint and inversion of data with low signal/noise ratio. The analyses of its stability and its sensibility to noise show that GA is quite noise resistant. GA is initially used in interval velocity inversion of seismic data and displays its potentiality in seismic data...

Capacitated single machine scheduling (CSMS) problem is a variant of the classical bin-packing problems. In this paper, we mainly study its on-line scheduling and apply some heuristics for bin-packing like next-fit (NF), next-fit-decreasing (NFD), next-fit-increasing (NFI), first-fit (FF) and first-fit-decreasing (FFD), to CSMS. There are four sections in this paper. Data constraints are given in Section 1. Sections 2 and 3 respectively present the worst case ratios when NF, NFD, NFI, FF, FFD are applied....
