Using Problems to Introduce some Tools and Technologies for Implementation of Graphics and Animation in C#

This paper is devoted to the learning of event programming by using Visual C# in specialized training in Informatics in high schools. Some basic tools and technologies for the implementation of graphics and animation in C# are discussed. Two example problems are proposed

Success and failure factors of the mergers and acquisitions performance : evidence from Bulgaria

This paper presents a study on the success and failure factors that influence the mergers and acquisitions (M&A) performance. In the initial part major theoretical studies, developed in the field of strategic management, corporate finance, organisational studies, and human resources are analysed. These works are used to outline ten main elements that can be considered essential for the success of the transactions. The discussed examines are founded on a number of leading theories – Agency theory, Resourced-based theory, Diversification theory, Learning theory, etc. Therefore, the empirical application of these theories is tested in the local context of the Bulgarian M&A deals. By the means of factor and regression analysis, three specific factors of successful M&A performance are empirically drawn. The conclusions are that leadership qualities of the managers, synergy of resources, and fast post-merger integration appear to be crucial for the successful performance of these strategic combinations.peer-reviewe

New Binary Extremal Self-Dual Codes of Lengths 50 and 52

* This work was partially supported by the Bulgarian National Science Fund under Contract No. MM – 503/1995.New extremal binary self-dual codes of lengths 50 and 52 are constructed. Some of them are the first known codes with such weight enumerators. The structure of their automorphisms groups are shown

Some MDS Codes over Gf(64) Connected with the Binary Doubly-Even [72,36,16] Code

* The author is supported by a Return Fellowship from the Alexander von Humboldt Foundation.MDS [8,4,5] codes over a field with 64 elements are constructed. All such codes which are self-dual under a Hermitian type inner product are classified. The connection between these codes and a putative binary self- dual [72,36,16] code is considered
