DRIMERA: New Model of Airborne Pesticide Dispersion by Eulerian Approach Coupled with Weibull’s Law and Wind Rose
(Wydawnictwa AGH, 2025) Kouadio, Kouassi Saint-Pierre; Assidjo, Nogbou Emmanuel
To solve the constraints that are commonly faced in risk assessment, research on the modeling of the dispersion and distribution of pollutants in the environment are emerging, and software is being developed. This paper presents a tool that is based on the Eulerian approach coupled with Weibull’s law and the wind rose approach (called DRIMERA). This physically detailed modeling-based software can accurately predict pesticide drift under different weather conditions and calculate aerially applied pesticide concentrations in the environment at a threshold of $p$ = 0.05; the values of the coefficient of determination $r^2$ vary between 0.6331 and 0.9876. This support thus helps facilitate the wider use and adaptation of atmospheric models.

Enhancing mesh adaptation capabilities of GetFEM++ “FEM engine” with MAdLib library
(2013) Perduta, Anna
This paper describes enhancing mesh adaptation capabilities of GetFEM++ library. GetFEM++ is a versetile software package in C++ for implementing FEM based solvers for partial differential equations. Although GetFEM++ offers a wide range of mathematic tools for model descripion and discretization, it does only provide basic mesh refinement facilities. To enhance GetFEM++ capabilities, a mesh adaptation package MAdLib is used. The paper discusses basic requirements for mesh adaptation packages and presents MAdLib basic usage. The paper discusses implementation issues related to integration of both libraries. Examples illustrate capabilities of mesh adapation package and FEM framework extended by mesh adaptation facilities.

Finite element implementation of nonlinear thermo-elasticity as typical coupling of diffusion and momentum balance
(2013) Putanowicz, Roman; Jaśkowiec, Jan; Pluciński, Piotr; Stankiewicz, Anna
The formulation and algorithmic aspects of nonlinear thermo-elasticity are reviewed in the paper. The attention is focused on coupling due to thermal expansion and temperature dependence of elastic model parameters, and on the consistent linearization of the ensuing nonlinear set of equations for two-field finite elements. Non-stationary heat flow, static loading and small strains are assumed. The solutions of some benchmark examples, obtained using the developed finite element environment FEMDK, are presented. The formulation has a more general application domain in the context of arbitrary coupling of a nonstationary diffusion proces and momentum balance.

Grounds for the selection of software components for building FEM simulation systems for coupled problems
(2011) Putanowicz, Roman
This paper discusses rationales for selection of software components for building scientific simulation tools. Nowadays no single research team has the resources or knowledge to build non-trivial simulation software form scratch. Sharing experience about the motives behind the choice of software components and the consequences of particular decisions seems a valuable knowledge as it can help to avoid some potential traps. In the paper we discuss software selection decisions for our problem solving environment for numerical modelling of coupled problems. For selected tools we discuss pros and cons of their use and mention potential alternatives. The detailed discussion concerns implementation of a solver for thermoelasticity problems.

Krótkookresowe planowanie robót górniczych z wykorzystaniem oprogramowania MineScape w BOT KWB »Bełchatów« SA
(2007) Frankowski, Ryszard; Gądek, Andrzej; Sośniak, Edward
Short-term mining activity planning has being carried on in BOT KWB Bełchatów SA since late seventies of last century. Work-plans for primary machines are being prepared for all stripping & mining levels of Bełchatów and Szczerców pits as well as spoil-banks of each pit individually. In it's mining part, a work-plan includes following types ot information: current pit geometry, location of drill holes, current and planned location of relevant conveyor belt together with conveyor segments numbering (every 10th segment numbered), descriptions of planned mining technology activities. In it's geological part a work-plan include information on total volume, quantity & quality of coal and accompanying minerals, planned for excavation in a given mining-pass, natural hazards, equipment left in drill holes, cartographic picture of current mining bench. Considering the amount of data gathered and documented on a work-plan map, and amount of work involved in creation of such maps/documents, ever since early nineties of last century a computer-based systems have been used to support the process of creating them. In the mining part of a work-plan creation it was UK based software system called MOSS/TM (and it's newer version called MX/TM). For geological part it was UK based system DATAMINE/TM and computer programs created by Poltegor-Instylut (database + related programs). In 2004 BOT KWB Bełchatów SA purchased software system called MINESCAPE/TM produced by an Australian software company MINC0M/TM. Based on digital models of deposit geology, considering areas of expected natural hazards, technical parameters of machines and also based on long-term mining plans (so called directive mine designs), the excavator work-plan is being created using MINESCAPE/TM system.

Oprogramowanie i integracja stanowiska do badania sygnałów akustycznych stanów przedawaryjnych maszyn elektrycznych
(Wydawnictwa AGH, 2009) Głowacz, Adam; Dobrowolski, Grzegorz
The purpose of the work is to present software and integration of work station for investigation of acoustic signals of imminent failure conditions in electrical machines. The proposed approach allows you to specify the tasks of the system, followed by the construction of work station. The work station allows you to investigate different algorithms depending on considered electrical machine.

Possible use of Voxler and MicroSation I/MINE programs in surveying
(2010) Lewińska, Paulina
This article revolves around two new programs. Voxler published by Golden Software and I/MINE an expansion to Bentleys MicroSation. It shoves the use of bought products in survey, visualizations and analyses. The similarities and differences between the key options of both programs and final effects are shown clearly. The main focus of this article is on ways of imputing gathered data, grid options, visualization, editing 3D images and in case of I/MINE analysis. There are given some examples of the above. The final conclusion is that I/MINE can be far more useful in survey purposes. It gives a wider range of options, analysis and is much more user friendly.
