Fatigue damage plays an increasingly important role in the design of various safety critical components that are exposed simultaneously to thermal and mechanical loads. Non-isothermal conditions, as these are to be found in turbine components, rocket engines, but also in high-speed machining tools makes the understanding even more complex. As the nature of those loading histories is mostly multiaxial, design engineers are interested in material models, which take into account the complexity of stress state and temperature history as well. The experimental validations of those models require sp

Film adaptation is a popular approach to game design, but it prioritizes blockbuster films and conventional “game-like” qualities of those films, such as shooting, racing, or spatial exploration. This leads to adaptations that tend to use the aesthetics and narratives of films, but which miss out on potential design explorations of more complex cinematic qualities. In this article, I propose an experimental game design method that prioritizes an unconventional selection of films alongside strict game design constraints to explore tensions and affinities between cinema and videogames.

First, the power-grid architecture is described. Then, the principle of Experimental Design is recalled. Next, the methodology is applied to power-grid modelling. Finally, we propose an analysis of the statistical moments of the experimental design results. Se

Optimizing an experimental design is a complex task when a model is required for indirect reconstruction of physical parameters from the sensor readings. In this work, a formulation is proposed to unify the probabilistic reconstruction of mechanical parameters and an optimization problem. An information-theoretic framework combined with a new metric of information density is formulated providing several comparative advantages: (i) a straightforward way to extend the formulation to incorporate additional concurrent models, as well as new unknowns such as experimental design parameters in a prob

In this study a four-factor response surface design is presented to study the fiber spinning process in detail at the lab scale. The time, cost, and amount of raw material required to execute the proposed design are compared to the typical completely randomized 24 factorial design used in fiber spinning experiments and also to a standard four-factor response surface design.

In the field of chemical engineering, mathematical models have been proven to be an indispensable tool for process analysis, process design, and condition monitoring. To gain the most benefit from model-based approaches, the implemented mathematical models have to be based on sound principles, and they need to be calibrated to the process under study with suitable model parameter estimates. Often, the model parameters identified by experimental data, however, pose severe uncertainties leading to incorrect or biased inferences.

Model checking technique can give a specific counterexample which explains how the system violates some assertion when model does not satisfy the specification. However, it is a tedious work to understand the long counterexamples. We propose a genetic algorithm to enhance the efficiency of understanding long counterexample by computing the minimal unsatisfiable subformula. Besides, we also propose a Craig interpolation computation-based method to understand counterexample. The causes which are responsible for model failure are extracted by deriving interpolation from the proof of the nonsatisf

In the case of AR, there is free radical oxidation of NADPH by autoxidizing monosaccharides, which is enhanced in the presence of the NADPH-binding protein. Thus any assay for AR based on the oxidation of NADPH in the presence of autoxidizing monosaccharides is invalid, and tissue AR measurements based on this method a

The optimization design of complex nonlinear structures mainly relies on expert experiences and trial and error. In this paper, we proposed an optimization design framework for nonlinear structures by combining experimental data and machine learning. The framework can search the entire design space and guide the next experiment by machine learning model until the optimization targets are met. To demonstrate the effectiveness and practicability of this framework, we have optimized the damping efficiency and principal resonance frequency (PRF) of an Electricity Distribution System (EDS) with eig

Appropriate experimental design and sample preparation are key steps in metabolomics experiments, highly influencing the biological interpretation of the results. The sample preparation workflow for plant metabolomics studies includes several steps before metabolite extraction and analysis. These include the optimization of laboratory procedures, which should be optimized for different plants and tissues. This is particularly the case for trees, whose tissues are complex matrices to work with due to the presence of several interferents, such as oleoresins, cellulose. A good experimental design

A new organic-inorganic complex based on copper ions with pullulan polysaccharide can be used for the treatment of copper deficiency in human organism. Therefore, the aim of this paper was to carry out the stress stability study of this potential active substance by the use of mathematical modelling. A full factorial design was successfully applied for the stability studying. The electrical conductivity was taken as the response, while the degradation time, concentration of the oxidative agent, temperature, and pH value were used as the independent variables. All process variables were analyze

One of the most important characteristics taken into account when designing machines is their efficiency. Active fluid-film bearings are able to influence tribological processes and reduce frictional energy, which increases the efficiency of the machine. For experimental determination of friction and verification of simulation results, an experimental complex was created, which makes it possible to directly measure the moment of friction force in active journal bearings. The complex is based on a rotor-bearing system with a rigid rotor on one active and one passive bearing. The information-mea

This article presents a systematic approach to formulate and experimentally validate a novel Complex Fractional Order (CFO) Linear Quadratic Integral Regulator (LQIR) design to enhance the robustness of inverted-pendulum-type robotic mechanisms against bounded exogenous disturbances. The CFO controllers, an enhanced variant of the conventional fractional-order controllers, are realised by assigning pre-calibrated complex numbers to the order of the integral and differential operators in the control law. This arrangement significantly improves the structural flexibility of the control law, and

With the rapid development of nanotechnology, the need to improve the efficiency of material grinding processes has increased. One of the criteria for the effectiveness of the process is the product fineness. There are various types of mills for grinding materials, one of which is stirred media mills. The article presents the results of experimental studies of a new design of stirred media mill on the example of sand particles size reduction. The principle of operation of the new mill is based on the organization of complex radial and axial impact on the particles of the material by grinding b
