Predicting Fluid Properties in the MUFITS Reservoir Simulator with User-Supplied Modules

We present a recent development of the MUFITS reservoir simulator aiming at modelling the transport of fluids whose properties and phase equilibria are calculated in a user-supplied external shared library. Both the explicit correlations and tabulated data for the fluid parameters can be implemented in the library that we name the EoS-module (Equation of State-module). An iterative approach—which, for example, is based on the phase equilibria calculation through the Gibbs energy minimisation (GEM) method, can also be used in the EoS-module. A considerable effort has been undertaken to minimise the number of program procedures exported by the shared library. This should facilitate and ease the usage of the developed software extension by the scientific community. Furthermore, we supplement the article with the source code of two simple EoS-modules that can serve as templates in other modelling and software development efforts. The EoS-modules are also useful for coupling MUFITS with other elaborate software for fluid property prediction. To demonstrate such a possibility, we supplement the article with the source code of a more complicated EoS-module that couples MUFITS with the geochemical code GEMS3K. This module is used in a simple 1-D benchmark study showing the capabilities of MUFITS for modelling reactive transport in porous media.

Expanding the Functionality of Optical CAD Using the Python Scripting Language

Nowadays, scripting is becoming a basic functionality in a very large number of different applications. This paper considers the experience of expanding the program capabilities of the optical modeling system using the Python scripting language. A brief overview of existing solutions is discussed. The approach based on the method of using the unified entity interface is proposed, which makes the process of expansion of the system simple and convenient for both its developers and end users. The new program modules like script interpreter,script editor and built-in parametric object libraries have been designed and integrated into the optical modeling system to work with scenarios are considered in detail. Software extension mechanism by means of adding new script-based object classes is provided. Examples of using Python API for a number of simple operations and examples of work with some simulation and automation modules based on scenarios are considered.

Intelligent programming of robotic flange production by means of CAM programming

The article deals with the description of the production programming of a robotic flange, which consists of outer conical, cylindrical surface, face area and internal threaded surfaces. For the modelling of a 3D model and the generation of production design, the Autodesk Inventor Professional 2018 software was used. To enter the semi-finished piece, select individual tools, cutting conditions, simulation and the NC program generation for RS Fanuc, the HSMPRO 2018 software extension was used. The circularity deviation was measured using the Roundtest RA 120 measuring device. The mean arithmetic values of roughness for the hole were: D = 126, Rz = 11.43 μm, Ra = 1.92 μm. The circularity deviation was 22.3 μm.

Rancangan Aplikasi SMS Gateway untuk Pemesanan Pendaftaran Service Sepeda Motor di AHASS XYZ

Astra Honda Authorized Service Station xyz (AHASS xyz) is a company engaged in the service providers maintenance and sale of spare parts specific to honda motorcycle brand. As a company engaged in the field of services, quality of service is very important to be kept and improved. To get the service of the astra's motorcycle service honda authorized service station (AHASS), is the official workshop AHASS motorcycles honda brand that caters to special care, motorcycle sales and sales of motorcycle-specific spare parts brands Honda. At AHASS xyz customers have to stand in line for quite a while because of the many customers who also want to get service service motorcycles, these conditions that make customers uncomfortable because a lot of time wasted in vain for wait queue service. The purpose of this research is to reduce the waiting time a prospect at the moment will be doing maintenance on a motorcycle at AHASS. In this system the design of the data collection method that is used for library studies, interviews and observations. Systems development methods are used, use the method waterfall, the programming language that is used in the design is the PHP and using software extension gammu and database using MySQL. Based on research done then SMS Gateway application system design for booking registration service AHASS motorcycle. You can make a good solution to overcome the problem of queues and waiting times that occur in AHASS xyz.

SwarmSim: a framework for modeling swarming unmanned aerial vehicles using hardware-in-the-loop

Unmanned Aerial Vehicle (UAV) swarm applications, algorithms, and control strategies have experienced steady growth and development over the past 15 years. Yet, to date, most swarm development efforts have gone untested and unimplemented. The major inhibitors to successful swarm implementation seem to include the cost of aircraft systems, government imposed airspace restrictions, and the lack of adequate modeling and simulation tools. This paper examines how the open-source OpenEaagles simulation framework was leveraged to bridge this gap to create Hardware-in-the-Loop (HIL) simulations. Leveraging OpenEaagles through software extension to create HIL simulations provides developers with a functional capability with which to develop and test the behaviors of scalable and modular swarms of autonomous UAVs. Using HIL-based simulations in this capacity provides assurance that defined behaviors will propagate to live flight tests in the real world. The demonstrations in the work show how the framework enhances and simplifies swarm development through encapsulation, possesses high modularity, provides realistic aircraft modeling, and is capable of simultaneously accommodating multiple hardware-piloted and purely simulated swarming UAVs during simulation.

Modelling of Wind Turbine Fall-Induced Vibrations Near Buried Steel Transmission Pipelines: An Updated RAMCES Software Extension

At CRIGEN, the GDF SUEZ research center for gas and new energies, a project on risk management on gas infrastructures (MARTHO project) is aimed, among other goals, at protecting the pipelines against external aggressions such as vibrations. Over the past few years, extensive construction of wind turbines has taken place all around the world in areas where many steel pipelines are already buried. The possible fall of these heavy machines may induce damageable vibrations to the pipeline. The common threshold used by the industry, established by the American Gas Association, is stated at PPV ≤ 50 mm.s−1. A more accurate and less conservative model of vibration propagation has been developed and validated by extensive field measurements coupled with a nonlinear 2D-finite element model for the soil. An experimental soil characterization through MASW tests coupled with vibration measurements was performed in a representative soil. As a result, safety distances between wind turbines and pipelines were considerably shortened compared to the previous model. The updated model is now part of the RAMCES software which has been developed for more than a decade at CRIGEN and is widely used in France by transmission operators.
