ORIGINAL DEVELOPMENT OF ALGORITHMS

The activity primary research is todevelop algorithms to solve computer problems.

To develop the CAD / CAM system for the textile industry, and I found developed an algorithm for finding a "place" very good for a polygon in a map consists of a rectangle some polygons in it. The algorithm is optimal if when consumption of the material exceeds a certain limit. The main movements "Permissions" for the current polygon are rotation and translation. The algorithm was tested by analyzing cases, and then has been optimized for all cases. In this way a map represents a starting point for the interactive process of creation of a map "optimized".

For the same CAD / CAM system I developed the following algorithms:
- from a map, a current polygon and a position limit, polygon can be calculated if the current does not affect any other polygon, remaining the inside of the current rectangle
- from a map, a polygon and a fixed current, I found an algorithm that calculates an optimal position using the passing and lane and follow a certain direction.

All the algorithms have been optimized for low consumption of resources: memory and processor activity.

COMPUTER SECURITY

An 'other direction in which the activity was concentrated Research is the computer security.For example, I developed and improved algorithms permetonno you to "hide" data within the media, without changing in appearance la the quality of media.

I developed and optimized an algorithm that allows you to organize in a certain manner a removable disk fully encrypted, where the algorithm encryption and 'the 3DES (triple DES), but in theory can' be any type of encryption. The disc becomes visible to the operating system after MOUNT type of an operation and becomes invisible after a process of type unmount. Was just the disk can 'be used as a removable disk normal.

Another research direction was the creation and optimization services and drivers, under MSWindows operating system, with various tasks and functions. Services manages cryptographic tokens. It also deals communicate with client applications.

The future research relates to the field of cryptography and then network security.
