Abstract:

Ultrasonic-guided wave sensing relies on perturbation of wave propagation by changing physical properties of the target media. Solid waveguides, through which guided waves can be transduced between the transducer and the target media, are frequently employed for liquid sensing and several other applications. In this manuscript, liquid sensing sensitivity of dispersive quasi-Scholte waves, which are guided interface waves that travel at the solid-liquid boundary, is investigated. Dispersion analysis of quasi-Scholte waves is done and sensitivities of quasi-Scholte waves to changes in fluid dens

Abstract:

We propose two enhancements of quasi-Newton methods used to accelerate coupling iterations for partitioned fluid-structure interaction. Quasi-Newton methods have been established as flexible, yet robust, efficient and accurate coupling methods of multi-physics simulations in general. The coupling library preCICE provides several variants, the so-called IQN-ILS method being the most commonly used. It uses input and output differences of the coupled solvers collected in previous iterations and time steps to approximate Newton iterations. To make quasi-Newton methods both applicable for parallel

Abstract The aim of this investigation is to optimise the data post-processing techniques associated with hot film sensors when intended to be used as a means of accurate, high-resolution heat flux measurement. More specifically, this project focuses on the performance of hot film sensors operated in a constant temperature anemometer bridge, used in conjunction with impinging jet air flows. The characteristic heat transfer behaviour in this impinging jet flow provides the reference against which the heat flux data attained using the hot film sensor is compared.

AbstractQuasi-Monte Carlo methods and stochastic collocation methods based on sparse grids have become popular with solving stochastic partial differential equations. These methods use deterministic points for multi-dimensional integration or interpolation without suffering from the curse of dimensionality. It is not evident which method is best, specially on random models of physical phenomena. We numerically study the error of quasi-Monte Carlo and sparse grid methods in the context of ground-water flow in heterogeneous media.

Abstract:

Springback compensation for symmetrical and quasi-symmetrical sheet metal parts presents specific challenges. The common approach involves modifying forming tools in the opposite direction of the springback to achieve dimensional accuracy. However, asymmetrical springback effects, such as twisting, can occur even in symmetrical parts. These effects should not be compensated, as they are typically unstable, whether numerical or physical. Numerical distortions can be avoided using symmetry boundary conditions in simulations, but this is not always advisable for quasi-symmetrical parts or symmetr

During the survivorship seasons, CS face several short-term, long-term, persistent, and late-emerging health and psychosocial problems, including cancer-related pain, fatigue, menopausal symptoms, anxiety, depression, distress associated with the risk of cancer recurrence, chronic uncertainty, social disruption, alterations of sleep, sexual and cognitive dysfunctions.

Purpose: To describe the effects of two interventions, regular Physical Education classes plus free active break times and school Physical Education plus Slackline classes during free time, on the attention of schoolchildren. Methods: This is a quasi-experimental study with a quantitative approach. Two groups participated in the interventions: body balance training (Slackline group) (n: 10; age: 7,8±1,93) and free-time activities break (FTA group) (n: 10; age: 7,8±1,22). Attention was assessed using the D-2 test. Repeated measures ANOVA was used. The magnitude of the effect size was estimated

Football is a sport that requires high endurance. Activities on the field that require running fast carrying the ball or chasing opponents. The need for physical endurance training to play football well. Physical training can be divided into various forms. One of these divisions is based on the use of oxygen or the dominant energy system used in an exercise, namely aerobic and anaerobic training. The research method is a quasi-experiment that the quasi-experimental method is a research method that remembers that not all variables (symptoms that appear) and experimental conditions can be given

Abstract:

Three ultrahigh molecular weight polyethylene (UHMWPE) composites of differing composition, reinforced with multiwalled carbon nanotubes (MWCNT) were prepared. The homogeneous distribution of MWCNT has been attempted by two dry blending methods and one melt-mixing process. The efficiency of the various methods was characterized by their effects on the quasi-static and dynamic physical properties of the composites. In the case of composites manufactured by ball milling the effects of various adhesion promoter additives (compatibilizers) has also been studied by analyzing the tensile, flexural,

Abstract:

The influence of flow characteristics and gas physical properties on nasal resistance (NR) is difficult to ascertain with traditional rhinomanometric methods because the respiratory airflows used in these methods are largely uncontrolled. As an alternative, we used a novel method of rhinomanometry in which an externally generated flow is passed through the nasal passage via a mouthpiece. The transnasal pressure-flow relationships for both quasi-steady and oscillating flows and with different gases were obtained in five healthy adults with this method. For quasi-steady nasal flows the dimension

The approximate solution is based on an expansion in asymptotic series and has limitations: for sinusoidal field, the solution is limited to frequencies above the lower limit; for pulsed field, the solution is limited by the initial tim

Recently, the study of quantum materials through thermal characterization methods has attracted much attention. These methods, although not as widely used as electrical methods, can reveal intriguing physical properties in materials that are not detectable by electrical methods, particularly in electrical insulators. A fundamental understanding of these physical properties is critical for the development of novel applications for energy conversion and storage, quantum sensing and quantum information processing.

The paper is focussed on numerical simulations of the fracture of a quasi-brittle specimen due to its impact onto a fixed rigid elastic plate. The failure of the specimen after the impact is modelled in two ways based on the physical discretization of continuum: via physical discrete elements and pseudo-particles. Advantages and drawbacks of both used methods are discussed. The size distribution of the fragments of the broken specimen resulting from physical discrete element model simulation follows a power law, which indicates the ability of the numerical model to identify the fractal nature
