Opis:
The purpose of the paper is to explore the problem of modeling technological assembly process, particularly generating assembly sequence for parts and machinery sets. A new computer program Msassembly is introduced. The program was invented by the authors on the basis of an algorithm for determining assembly sequence for parts and machinery sets. The algorithm is based on hypergraphs and directed graphs, as well as on assessment of transitions between assembly states. The principles of operation of Msassembly are presented on the example of modelling the assembly sequence of a ball joint. At the end of the paper, research findings are submitted.

Opis:
The paper presents the analysis of use of IT technologies by farmers. Data from a research survey carried out in 100 randomly selected farms in 2015 constituted research material. The research area covered farms located in Podlaskie Voivodeship on the area of two counties i.e. Wysokie Mazowieckie (50 questionnaires) and Zambrów County (50 questionnaires). The questionnaire is a research instrument. The research was to determine the level of use of specialist computer programs by farmers and their needs concerning acquisition of information on innovations in agriculture. Due to the obtained results one may find out that a low number of farmers uses specialist computer programs in their farms. In Wysokie Mazowieckie County it is only 8% of respondents and in Zambrów County 14%. The main source of information on innovations in agriculture is the Internet, professional agricultural press and television.
W pracy przedstawiono analizę użytkowania przez rolników technologii informatycznych. Materiał badawczy stanowiły dane pochodzące z badań ankietowych przeprowadzonych w 100 losowo wybranych gospodarstwach rolnych w 2015 roku. Obszarem badań objęto gospodarstwa położone w województwie podlaskim na terenie dwóch powiatów tj. wysokomazowieckiego (50 ankiet) oraz zambrowskiego (50 ankiet). Instrumentem badawczym był kwestionariusz wywiadu. Badania miały na celu określenie poziomu wykorzystania przez rolników specjalistycznych programów komputerowych, a także jakie są ich potrzeby w zakresie pozyskiwania informacji o nowościach w rolnictwie. Uzyskane wyniki badań pozwalają stwierdzić, iż niewielka liczba rolników wykorzystuje specjalistyczne programy komputerowe w swoim gospodarstwie. W powiecie wysokomazowieckim tylko 8% respondentów a w powiecie zambrowskim 14%. Głównym źródłem pozyskiwania informacji o nowościach w rolnictwie jest Internet, fachowa prasa rolnicza oraz telewizja.

Opis:
Microarray methods have become a basic tool in studies of global gene expression and changes in transcript levels. Affymetrix microarrays from the HGU133 series contain multiple probe-sets complementary to the same gene (4742 genes are represented by more than one probe-set in a microarray HGU133A). Individual probe-sets annotated to the same gene often show different hybridization signals and even opposite trends, which may result from some of them matching transcripts of more than one gene and from the existence of different splice-variant transcripts. Existing methods that redefine probe-sets and develop custom probe-set definitions use mathematical tools such as Matlab or the R statistical environment with the Bioconductor package (Gentleman et al., 2004, Genome Biol. 5: 280) and thus are directed to researchers with a good knowledge of bioinformatics. We propose here a new approach based on the principle that a probe-set which hybridizes to more than one transcript can be recognized because it produces a signal significantly different from others assigned to the particular gene, allowing it to be detected as an outlier in the group and eliminated from subsequent analyses. A simple freeware application has been developed (available at www.bioinformatics.aei.polsl.pl) that detects and removes outlying probe-sets and calculates average signal values for individual genes using the latest annotation database provided by Affymetrix. We illustrate this procedure using microarray data from our experiments aiming to study changes of transcription profile induced by ionizing radiation in human cells.

Opis:
The article presents the authors’ computer program for designing and dimensioning columns in reinforced concrete structures taking into account phenomena affecting their behaviour and information referring to design as per EC. The computer program was developed with the use of C++ programming language. The program guides the user through particular dimensioning stages: from introducing basic data such as dimensions, concrete class, reinforcing steel class and forces affecting the column, through calculating the creep coefficient taking into account the impact of imperfection depending on the support scheme and also the number of mating members At load shit, buckling length, to generating the interaction curve graph. The final result of calculations provides two dependence points calculated as per methods of nominal stiffness and nominal curvature. The location of those points relative to the limit curve determines whether the column load capacity is assured or has been exceeded. The content of the study describes in detail the operation of the computer program and the methodology and phenomena which are indispensable at designing axially and eccentrically the compressed members of reinforced concrete structures as per the European standards.

The paper presents skeleton rule-based expert system of a new generation, named EXPERT 3.0, worked out and programmed by the Author. Notion of a new generation refers here to implementation of a knowledge base of the system in a form of a computer database; previous skeleton expert systems implemented knowledge bases as text files. At first, a theory of expert systems, as one of the branches of Artificial Intelligence, is briefly presented. Then the Author’s original algorithms of the system are described in the paper. Using the EXPERT 3.0 system, execution of the inference processes: forward, backwards or mixed, as well as of falsification of the main hypothesis, is possible. The EXPERT 3.0 system may be loaded with any number of parallel knowledge bases from such domains as technical, medical or financial diagnostics, as well as providing equipment, forecast and many other systems; in the paper, the inference process is illustrated by an example of the diagnostics of the damage to a MKM33 coal mill, working in a 200 MW power unit. Finally, conclusions and recommendations are formulated in the paper.

Opis:
A modular computer program named SPPMEF has been developed which isintended for purposes of predicting internal ballistic performances of solid propellantrocket motors. The program consists of the following modules: TCPSP (Calculation of thermo-chemical properties of solid propellants), NOZZLE (Dimensioning of nozzle and estimation of losses in rocket motors), GEOM (This module consists of two parts: a part for dimensioning of the propellant grain and a part for regression of burning surface) and ROCKET (This module provides prediction of an average delivered performance, as well as mass flow, pressure, thrust and impulse as functions of burning time). The program is verified with experimental results obtained from standard ballistic rocket test motors and experimental rocket motors. Analysis of results has shown that the established model enables high accuracy in prediction of solid propellant rocket motors features in cases where influence of combustion gases flow on burning rate is not significant.
