In this paper, we present a short literature review on the studies and researches, especially recently, in the area of modeling of the trajectory-generating equipments of the five-axis CNC machines and modeling of the trajectory-generating mechanisms of the serial industrial robots. First we make a short introduction regarding the importance and the opportunity of using modeling and simulation techniques...
This paper joins the developing trend of modeling distributed generators based on dq0 quantities, and proposes an open-source software for modeling and analysis of large-scale power networks based on dq0 signals. The dynamic models describing the network are provided as state-space objects that are sparse and of minimal order. The software supports integration of various models of synchronous machines,...
This paper summarizes the results of a three year long project concerning the validation of Geant4-based simulation of electron backscattering. Accurate simulation of backscattering is of great importance in many experimental scenarios from calorimetry to medical dosimetry, as it affects the pattern of energy deposition in detectors or other kinds of sensitive volumes. All Geant4 multiple and single...
Compared the mechanical adjustment with hydraulic position closed-loop adjustment, the structure of mandrel supporting device of rolling tube machine is analyzed in this paper, then the AMESim software is applied to model the position closed-loop control hydraulic system dynamics based on its structure parameters, where the simulation results play an important role in designing the hydraulic control...
The article presents a universal simulation model of the general unsignalized intersection consisting of three (T intersection) or four arms. Each arm can consist of up to 5 lanes. The model is based on gap acceptance theory which defines rules for entering the intersection. The simulation model is created using software Witness. The main advantage of the presented approach is that defining all the...
Model-based systems engineering is an increasingly accepted method supporting design decisions. System engineers or modelers have the choice between tools and system description languages that are either abstract and generic or specifically adapted to their domain. The latter approach is easier and more efficient but restrictive. The success of this approach strongly relies on the support of domain-specific...
Medical devices help physicians to diagnose and treat patients at home and healthcare facilities. However, when complexity of devices grows, new risks can also arise and put users in hazard situations. Manufacturers must develop medical devices taking into account ways to mitigate risks and avoid injuries to users. In this context, regulatory agencies impose the ISO 14971 standard during the risk...
Implementation of the sustainable policy guidelines at a company level is not an easy task. The decisions about resource allocation, changes in process organization or new investments should be considered taking into account their economic, environmental and social effects. Remanufacturing processes contributes to the fulfilment of the circular economy paradigm. The existing body of literature highlights...
In Software Defined Networks (SDN), each flow table entry is dedicated to an individual flow and has an idle timeout value associated with it. Due to limited flow table and controller processing resources, SDN suffers from scalability problem especially when dealing with a large number of flows. As Instant Messaging (IM) applications usually generate too many different flows and idle timeout has effect...
Context: Continuous Improvement in manufacturing to attain manufacturing excellence is today's requirement. It gives cutting edge over the competitors. This has developed lot of interest for the researchers during the last few years. Vehicle Assembly Line being the most complex Assembly line has been active area of research over years and has attracted many researchers.
Parameter study is a widely spread type of scientific research methodologies used with modern High Performance and High Throughput Computing infrastructures such as Clouds. More and more often, parameter study experiments are oriented towards generating large amount of data describing complicated processes and phenomena. It becomes clear that new software for supporting such large-scale experiments...
Prototyping distributed embedded system can be seen as a collection of many requirements covering many domains. System designers and developers need to describe both functional and non-functional requirements. Building distributed systems is a very tedious task since the application has to be verifiable and analyzable. Architecture Analysis and Design Language (AADL) provides adequate syntax and semantics...
In public transportation, simulation provides capabilities of investigation of complex interactions between the components of the transportation system, including infrastructure, vehicles, passengers and intelligent transportation system. Although many simulation platforms (either commercial or open source) exist to test, validate and evaluate the performance of control systems, the development of...
Size and complexity of power systems impose significant challenges for the power system analysis and control. As the power system becomes more complex there is a great need to develop improved and sophisticated tools for power system analysis and simulation. These tools should be able to accurately replicate real events that occur in electric power network and help to understand dynamics of changes...
The dynamic behavior of complex systems is a well-known challenge within engineering. The major drawback of dependency modeling approaches for system analysis such as the Design Structure Matrix is that they depict a static view on the system and therefore only allow very limited statements about the dynamic behavior of systems even though the structure mainly defines the system's behavior. Approaches...
Electronic devices may act as unintentional radiators. Hence, the prediction of their breakdown behaviour is not possible by design. Instead, time-consuming measurements are necessary to determine their radiation patterns. Stochastic approaches help to do approximations, but need to be validated e.g. by numerical field simulations. In this paper, simulation objects are created by the use of the software...
Simulation experiments generate large data sets that must be converted into recommendations for decision makers. This article explores using a Natural Language Generation (NLG) approach for writing summaries of simulation experiments. The article discusses the steps required to convert simulation experiment data to text and highlights the unique aspects of data to text for simulation experiments....
