The aim of this paper is to add to the genealogical structure of breeding Black and White cattle, to analyse their productivity and other profitable features of farms by methods of genetic statistics. The Results of Survey. The first line of Black and White bulls in Lithuania were Plessas LT 149, Gulbių Riteris LT 277, Olaf LT 276, Hanmaksas LT 1200, Kraft-Stipruolis LT 1201, Garsas LT 200 and etc. In Lithuania a new period of creation and breeding of Black and White genealogical structure started when Black and White cattle from Holland were used en masse in order to improve the cattle breed. The best Black and White bulls from Holland were chosen as initials. Those breeds were: Annas Adema 30587, Wytsturt Annas Adema 36079, Frizo Wouter 33116, Haubois Annas Adema 44162, Diamant 33251, Haskera Governeur 44506, Hiltjes Adema 37910, Rotterda Paul 36498, Jelsumer Rudolf Jan 42884 and Adema 25473. The evaluation of bull’s inheritable features was done with help of features of descendant’s productivity and cattle’s were chosen and bought very purposefully. From 1967 till 1976 the following breeds were created: B. Pieter LJ 305, Sietse LJ 340, Hildoj 363, Katso LJ 483, Vautero LJ 738 and some lines of Klaso LJ 335, Adema LJ 770. Paulio LJ 771, Imperatoriaus LJ 1160, Burto LJ 2085, LangerioLJ 2523 descent. In thirty latter years Black and White cattle’s in Lithuania were being intensively improved by Black and White breed from Holland, Denmark, England and Germany and by Holsteins... [to full text]

The doctoral thesis is concerned with the issues that are faced when selecting strategic analysis tools to be used in small and medium-sized enterprises (SME) in the process of strategic management. The paper comprises three parts. The first part presents a discussion on the methodology of strategic analysis and the application of its tools in SME. As a result, the taxonomy of 40 strategic analysis tools applied in business organizations (including SME) was designed. In addition, the „model of strategic tune“, defining the correlation of „a dominating strategy type“, „the size of an enterprise“, and „the nature of strategic analysis“, was formed in this part. The second part describes the methodologies to study the application of strategic analysis tools. In the course of research project, two individual empirical studies were conducted: 1) expert evaluation study of strategic analysis tools, during which the criteria for expert evaluation of 40 strategic analysis tools were prepared; 2) SME owners, executives and specialists‘ testing and survey. The third part of the thesis indicates the results of the study into the application of strategic analysis tools. While combining theoretical and empirical methods and using various classification criteria, four typologies of strategic analysis tools were designed. Factual material reflecting SME executives‘ scope of knowledge and their perceptions and attitudes towards strategic analysis was collected by means of testing and... [to full text]

This work is to compare two online testing systems – EDU Campus and TestTool4. The first one is using various types of standard test questions with the emphasis to math-based subjects. It has some unique features too. The second one is using graphical model based approach to the testing of the knowledge.

Lithuanian language is quite in an early stage of language processing. And therefore has a high demand on automated tools like taggers, parsers, word sense disambiguators etc. During the last 10 years only a few researchers were attempting to create a parser for Lithuanian language. However none of them are used in practices nowadays. The process of designing and implementing rule based parser for Lithuanian language is presented in this paper. Rules and constraints of the formal grammar follow the principles of Dependency Grammar. Necessary language recourses were made up at the Computational Centre of Linguistics. Research area analysis and overview of the most popular methodologies is presented here as well. Syntax parser of the Lithuanian language was evaluated against the Gold Standard and gave 80,2 % of accuracy of in recognizing parts of the sentence.

The aim of this work was to investigate the effect of fertilizers on chemical composition of raw pumpkins and quality of processed pumpkin products. The material consisted of two Cucurbita maxima 'Stofuntovaja' and 'Bambino' pumpkins cultivar. Pumpkins were grown at the organic pomological garden of the Lithuanian Agricultural University in 2004-2005. The fertilization treatment was: organic-humatic - 30 l ha-1, complex fertilizers (10:10:20 - 500 kg ha-1, compost (mixture of composted manure 70% and plant waste 40%) - 40 t ha-1, complex + organic-humatic fertilizers - 500 kg ha-1 + 30 l ha-1. Biochemical composition and quality of processed pumpkins products (jams, bread and wine) was analyzed. It was determinate better biochemical composition in raw pumpkins grown with complex + organic-humatic fertilizers. Better sensual characteristics had products processed from pumpkins grown with organic-humatic fertilizers.

Supervised classification methods are applied in many fields. The main problem of applying these methods is how to select the most appropriate method in particular case. The literary review was fulfilled and the advantages and disadvantages of mostly used criterion of supervised classification methods comparisons were ascertained. Then the methodology of comparisons was suggested. The analysis of SAS system procedures and macro commands was made. It was ascertained that there is not comfortable software which allows comparing the results of supervised classification methods. This work demands a lot of work, good knowledge of SAS programming language and high qualification in programming. So, the main purpose of this work is to expand the statistical data analysis system SAS possibilities in comparison of supervised classification methods and classificate various data. In this work the possibilities of SAS system are expanded by the tool which allows comparing quality of the linear, quadratic, kernel, nearest neighbor’s discriminant analysis and logistic regression analysis methods. There were used classification error estimates which were got by resubstition, cross–validation leave one out, bootstrap and Monte Carl cross–validation methods, although classification error confidence intervals which were got by non-parametric bootstrap method. The test of created tool was made with various data (different sample sizes, various classis separability, violations of assumptions... [to full text]

Aim of study. To evaluate the image of sanatorium „Tulpe“ in respect of its clients. Objectives: 1) to inspect means that sanatorium makes for image forming and 2) to investigate the image that is formed for different groups of clients Methods. Questionnaire survey, comparative analysis, statistical data analysis. The questionnaire made from 20 basic questions that had alternative choices. Statistical data analysis was performed with the statistical package SPSS 11.0 for Windows and Microsoft Excel. χ2 criterion was implemented for hypothesis evaluation.

The data base Projektas was created for search system. Specification of program modules was made up. Manuals... [to full text]

A new approach (designed to lower computational complexity) to compression of finite binary data, based on the application of “exclusive-or” operation, is presented in the paper. The new concept of an identifying sequence, associated with a particular decomposition scheme, is introduced. A new heuristic algorithm for calculation of the identifying sequences has been developed. Two robust algorithms – for compressing and streaming the sequences (using a priori compiled decomposition tables), and for real time decoding of the compressed streams – were proposed and implemented. The experimental results confirmed that the developed approach gave a data compression effect on an ordinary computer system.

The purpose of this Paper was to examine kinematic characteristics of a mechanism according to a given its kinematic schema and the dependency of the characteristics on parameters of the mechanism; to prepare a visual material for lectures and laboratory activities intended for students of physics and technology majoring in theory of machines and mechanisms. The Paper covers a review and interdependent comparison of basic methods of kinematic analysis: graphical, graphic-analytical and analytical. It is shown that in case of ordinary mechanism it is possible to make an ordinary mathematical model of mechanisms intended for examination of kinematic characteristics. Applying Visual Basic software there was a crank-slide-block mechanism and various cam-gears were designed and examined here. There are proposals given regarding application of this program during lectures and for preparation of tasks intended for laboratory activities of students.
