Along with fast development of computer science, traditional recognition forthe documents and literatures have replaced by the technique of computerauto-digitalization. Computer auto-digitalization is a popular techniquewhich not only has the merit of low labor cost, but also has comprehensivefunctional extensions (multi-status, for the detection, recognition,classification and storage). However, the problem is centered in thereliability and adaptation. Bad compatibility and error-prone are universalfeatures. So in this paper, taking a complex material, the civil aerialmeteorological map, as experimental goal, we developed a novel system forthe analysis of drawing map, and also introduced the detailed algorithms ofit. The superiority of algorithms and efficiency of system in generatingmeaningful interpretation are clear from experimental results.

This paper presents an off-line handwritten, isolatedcharacter recognizer based on the artificial immune system (AIS) andqualitative rules-based system (QRBS). AIS acts as an optimizer. It selectsthe best candidates for training. Each candidate is used from severalcharacter features previously selected based on some structural andstatistical techniques. QRBS works as a qualitative recognizer system. Itutilizes qualitative rules to recognize characters. It handles bothimprecision and uncertainty in handwriting during the training andclassification phases that make some characters unreadable and may decreasethe accuracy of the overall process. Experiments are conducted on the MNISTand English letter databases. Comparisons with other recent approaches usingthe same database indicate that this approach is effective.

Practical works for informatics students are an assured step to consolidatethe theoretical concepts acquired during the educational activities. Thesepractical works allow learners to deepen knowledge in a particular areathrough the development of the Internet. In this paper, we present acomputer-supported collaborative practical works system for the ``computerscience'' specialty, called TPCOLinfo. The designed system allows studentsto carry out practical works in groups and at distance. These groups areconstituted dynamically according to a new grouping method based on theresults of pre-tests done by learners before doing a particular newpractical work.TPCOLinfo allows to increase the skills of students in ``computer science''because the proposed grouping method aiming at creating dynamically groupshaving a homogeneous level. In other words, the system allows students towork in groups formed for learners with additional cognitive profiles andbetter interact with each other to achieve collaborative tasks. This systemhas been tested by students of a computer science department where weachieved very good results.

The automation processes industry has become increasingly expensive, whichis why some small and medium sized enterprises are incapable of buyingmachine tools with automatic systems. This means that their processes aremanual in many cases, and as a result they often have to rework theirdeveloped products due to the lack of precision and efficiency in theirproduction processes. Considering that current manufacturing systems withvariable machining and turning centers are gradually replacing dedicatedsystems for medium lot size production, the production systems' basicelement, the machine tool, must be capable of working at high speeds withprecision, and it must be reconfigurable. These systems must also becompatible and convertible in order to create economic benefits forcustomers. This article describes a specific software architecture designedto record all the data, information and knowledge concerning manufacturingsystems. The software allows for the creation of a new knowledge databaseand works with it in the reconfiguration of machine tools depending on therules, requirements and parameters needed to effectively modify productionprocesses or products.
