How to Make the T-ARGUS Modular Method Applicable to Linked Tables
نویسندگان
چکیده
The software package τ-ARGUS offers a very efficient algorithm for secondary cell suppression known as either HiTaS or the Modular approach. The method is well suited for the protection of up to 3-dimensional hierarchical tables. In practice, statistical agencies release multiple tabulations based on the same dataset. Usually these tables are linked through certain linear constraints. In such a case cell suppressions must obviously be coordinated between tables. In this paper we investigate into the possibilities for an extension of the modular approach to deal with linked tables.

They are three principal ways to deal with a secondary cell suppression problem in τ -Argus. The Hypercube algorithm gives a fast solution that may cause overprotection. The Optimal method solves a problem of Mixed Integer Linear Programming and the Modular approach enables to find more quickly a near-optimal solution for hierarchical tables. This paper discusses the advantages and disadvantage...
متن کاملA new method for venom extraction from venomous fish, Green Scat
Scatophagus argus argus (Green Scat) is a pretty aquarium fish. Its hard spines are venomous and can cause painful injury. In this study 60 specimens of Green Scat were collected periodically from coastal waters of Boushehr (south of Iran) from May 2011 to April 2012. Anatomical features of venomous spines were investigated. Scat venom was extracted from the spines in a new manner for keeping t...

In order to study the role of the kidney in fish osmoregulation, freshwater acclimatized juvenile spottedscat (Scatophagus argus L.) were subjected to four different salinities and observed for histomorphometricchanges of the kidney at 1, 2, 10 and 15 days post transfer time points. The overall morphological changesdisplayed by fish kidney included significant decrease in the density of collect...
متن کاملOptimization Models and Programs for Cell Suppression in Statistical Tables
There has been much international research in recent years on the cell suppression approach to protecting a statistical table. In this paper, the author compares some of the new and old methods from both a theoretical and practical point of view. The basic theoretical difference among the approaches is the type of mathematical programming method that is used to solve the optimization problem in...
متن کاملInvestigation the status of instructional design with modular method in medical education
Background and Goal: Modular method is a form of in-service training which provides job skills into a form of independent training of audiences. Each of modular provides specific skill and at the same time besides the other modular led to a new and comprehensive skill. In fact, any educational modular is a set of knowledge, attitudes and skills which by using them it can be possible to do ...
