“The state of the art” of computer programs, which have been developed for geodetic purposes, is portrayed in the following six papers. Each report has been condensed to give an indication of what the program can do, but no attempt has been made to indicate any detail of the programs. It is generally the experience of programers that a program is never static. By the time one edition has been checked out (“debugged” is the jargon of the craft), the programer has already started to work on the next edition. In this sense, many of the programs that were discussed in October may be superseded before this report is printed. In part, this reflects the rapid change in computer hardware. Computers, themselves, are frequently obsolete soon after they are put into service. Each change of computer requires at least minor changes in programs; more flexibility in programs, in turn, encourages more comprehensive analysis of the data and the selection of alternative formats for output data. In general, a much better job of data processing can be, and is being, done with the help of the electronic computer. It is the consensus that the user of a program must understand it and be capable of modifying it to suit his particular requirements. The dream of a general program into which anyone can feed his data and from which he will get perfect results remains a dream.

Abstract The personal computer is a powerful scientific and administrative analytical tool. Commercial computer programs can be effectively combined to meet most data-handling and report-writing needs. The selection of specific computer equipment (hardware) and computer programs (software) should be based on a careful assessment of the flow of work in the data-handling, statistical analysis, and reportwriting phases of analytical projects and on an assessment of the time and training required of the users of the computer system. In most projects, data must be transferred between different hardware and software. The use of standard ASCII text files is recommended for data transfer.

Two computer programs were used for simulation of continuous steel casting processes in frame of this work. In the same time industrial experiments by isotope technics were carried out for observation of solidification and shell thickness. The comparison of calculations and experimental results mutually verified the applicability of methods for more sophisticated control of continuous casting procedure.

Until recently, kinetic modeling of peritoneal dialysis (PD) was performed by engineers, scientists, or nephrologists at major teaching institutions. Now there are several “user-friendly” computer programs which permit the practicing nephrologist and dialysis staff to monitor adequacy of the individual PD patient and to optimize the dialysis prescription. In this brief article, the capabilities, methods, and data requirements of three programs are reviewed, and specific recommendations for the selection of a particular program are discussed.

Abstract. The calculated values of wind pressure are identified without taking into account changes in wind speed and pressure from different directions. Current load standards in Ukraine allow taking into account the decreasing coefficients of wind direction if there is sufficient statistical justification and when the objects are located on open flat terrain. The purpose of this work is to identify possible effect of considering the orientation of frame buildings and corresponding coefficients of the wind direction when designing steel columns of one-story frame buildings. By analyzing design and calculated parameters of one-story industrial and civil buildings, possible limits of their change were established, and a plan for the experimental design of columns from broad-flanged rolling H-beams was developed and implemented. A dependence was obtained and described by analytical expression that allow forecasting steel consumption for the columns of single-aisle one-story buildings, taking into account their height, total load from roof and active component of wind pressure. Based on the results of earlier studies, the characteristic values of wind pressure and generalized wind direction coefficients were established for each of 25 regions of Ukraine. For most part of the territory of Ukraine, minimum wind loads are realized when wind directions are north-south or north-east-south-west. Generalized wind direction coefficients, together with the formula for the forecasting mass of columns, made it possible to identify possible savings in steel on the columns of one-story buildings taking into account spatial orientation of buildings. On average, throughout the territory of Ukraine, metal consumption of rolling columns decreases by 4.2%, and in some cases, depending on the region, wind direction and building height, it can decrease to 17.5%. Significant influence of the underlying surface and surrounding buildings on the nature of the wind flow allows wind direction coefficients to be taken into account only when calculating the frames of buildings located in an open flat area, under conditions that their values are statistically substantiated using the results of wind observations at nearest meteorological stations.

Currently, specialists who use the skills of drawing, drawing, modeling and modeling in their work have largely begun to use the capabilities of computer technology and software. Working with digital models and three-dimensional modeling technologies are also within the competence of an industrial designer. This article att empts to make a selection of computer programs that are used in their work by industrial designers and classify the capabilities of this software according to its functional purpose. It is obvious that all the technologies of three-dimensional modeling listed in the article are very important for specialists engaged in technical aesthetics, artistic design, visualization, prototyping and prototyping of things.

The basics of the automated selection of mobile construction cranes on the parametric conformity of the mounted structures are outlined. The tasks of crane selection are solved based on the software package created: the position of the axes of movement and the position of the crane stops during the installation of one-storey industrial buildings is determined. The organization and technology of using mobile cranes on a pneumatic move is considered. Special attention is paid to cranes on the chassis of various types of cars of domestic and foreign production. The zones of admissible parking of cranes during installation and cargo handling operations are studied. The recommendations for determining the maximum and minimum allowable hook lifting using the above algorithms are given. The composition of the software package, service programs, a crane selection subroutine, a subroutine for checking the possibility of lifting a crane with a given arrow and modification, a subroutine for determining the crane parking area, service programs, a program for creating and maintaining libraries of crane characteristics are given. The article describes the algorithms and developed computer programs. The results of the calculations described in the work can be used at the stage of development the POS, PPR and in the analysis of new technological solutions. The recommendations and proposals are intended for research, design and construction organizations.

Simulation models describe the functioning of agro-ecosystems and the flow of processes in them using computer programs. With their help can be made computer experiments and to predict the behavior of agro-ecosystems. One of the main problems in the creation of simulation models is imitation of uncontrollable soil and weather factors. A number of studies of soil properties and meteorological characteristics indicate that these stochastic variables do not follow the normal (Gaussian) distribution. In the selection of statistical models that approximate the distribution of such stochastic variables, the most appropriate is a family of Johnson distributions. The article examines ways to generate pseudorandom numbers from Johnson and Burr distributions families for simulating soil and weather factors determining agro-ecosystems.
