Web-based projects are systems that implement logical set of steps aiming to take advantages of Internet regarding commercial company goals. The accuracy of evaluating the effectiveness of online projects is not just cost dependant but is determined also on results and costs comparing methods applied. The paper suggests various criteria of Web-based projects for tourist companies’ economic efficiency based on methodology of information systems with different functionality total cost of ownership.

Two-step procedure based on fuzzy cognitive simulation built team-building methodology for implementation of IT projects is suggested. Initially applicants’ levels of competency are assessed using test technologies and after that the optimal project tasks assignments to executives is determined.

Forms and methods of teaching programming university students for the course «Computer Science» based on modern information technology are discussed. Author believes that combination of object-oriented and system-oriented approaches meets the requirements of the discipline learning most of all.

An approach to data structure description simplifying data processing and increasing application efficiency is presented. Principle of the binary addressing is used for cube dichotomy data structuring.

Comparative analysis of popular image compression methods based on discrete cosine transform and fractal coding is presented. Image compression principles incorporating these approaches are discussed. The obtained results make it clear the promise of fractal coding technique implementation for image compressing tasks.

An approach to static code analysis that allows race conditions detecting is described. The method focuses on real tasks with complex code constructs, including loops and branches. The method proposed is based on a simulation of multi-threaded application performance and analysis of the model. The model is suitable for real-world problems, which are defined as those where the logic and the notion of correctness attached to the concrete values of variables and history of operations on shared variables rather than to their pair-wise comparisons.
