N = 1 designs imply repeated registrations of the behaviour of the same experimental unit and the measurements obtained are often few due to time limitations, while they are also likely to be sequentially dependent. The analytical techniques needed to enhance statistical and clinical decision making have to deal with these problems. Different procedures for analysing data from single-case AB designs are discussed, presenting their main features and revising the results reported by previous studies. Randomization tests represent one of the statistical methods that seemed to perform well in terms of controlling false alarm rates. In the experimental part of the study a new simulation approach is used to test the performance of randomization tests and the results suggest that the technique is not always robust against the violation of the independence assumption. Moreover, sensitivity proved to be generally unacceptably low for series lengths equal to 30 and 40. Considering the evidence available, there does not seem to be an optimal technique for single-case data analysis

This thesis studies the problems and their reasons a software architect faces in his work. The purpose of the study is to search and identify potential factors causing problens in system integration and software engineering. Under a special interest are non-technical factors causing different kinds of problems. Thesis was executed by interviewing professionals that took part in e-commerce project in some corporation. Interviewed professionals consisted of architects from technical implementation projects, corporation's architect team leader, different kind of project managers and CRM manager. A specific theme list was used as an guidance of the interviews. Recorded interviews were transcribed and then classified using ATLAS.ti software. Basics of e-commerce, software engineering and system integration is described too. Differences between e-commerce and e-business as well as traditional business are represented as are basic types of e-commerce. Software's life span, general problems of software engineering and software design are covered concerning software engineering. In addition, general problems of the system integration and the special requirements set by e-commerce are described in the thesis. In the ending there is a part where the problems founded in study are described and some areas of software engineering where some development could be done so that same kind of problems could be avoided in the future.

New economic and enterprise needs have increased the interest and utility of the methods of the grouping process based on the theory of uncertainty. A fuzzy grouping (clustering) process is a key phase of knowledge acquisition and reduction complexity regarding different groups of objects. Here, we considered some elements of the theory of affinities and uncertain pretopology that form a significant support tool for a fuzzy clustering process. A Galois lattice is introduced in order to provide a clearer vision of the results. We made an homogeneous grouping process of the economic regions of Russian Federation and Ukraine. The obtained results gave us a large panorama of a regional economic situation of two countries as well as the key guidelines for the decision-making. The mathematical method is very sensible to any changes the regional economy can have. We gave an alternative method of the grouping process under uncertainty.
