Abstract:

The increasing use of 3D-printed PEEK materials in load-bearing applications necessitates a comprehensive evaluation of their wear characteristics and hardness under dynamic loading conditions. This study investigates the wear loss, coefficient of friction, and hardness values of PEEK materials with four distinct surface patterns: Line, Grid, Cubic, and Hexagon. Controlled experiments revealed that the Line and Hexagon patterns exhibited the lowest wear loss (0.004 grams), indicating superior wear resistance, while the Cubic pattern showed the highest wear loss (0.009 grams). In terms of frict

Abstract:

The determination of actual stresses over the tool-workpiece interface has long been a matter of debate among researchers. Evaluation of the nature and the geometry of the wear contact area were always associated with many, sometime impractical, assumptions. The indeterministic fashion of edge wear and deformation requires a more realistic way to predict the actual wear contact area. In the current study, many wear area patterns are proposed considering the different wear modes of the cutting edge. The selection of the most correlated pattern to a specific edge deformation is justified using t

Abstract:

This study explores the mechanisms underlying the enhanced anti-wear and thermal fatigue performance of laser-treated bionic brake drums, aiming to extend their service life and improve design quality. Bionic brake drums treated with laser patterns—point, stripe, and grid—were tested with semi-metallic, non-asbestos organic (NAO), and ceramic brake pads. A mechanical model was developed to analyze wear performance, and bench tests were conducted to assess wear patterns. Thermal fatigue tests examined the impact of thermal cycling on the treated drums’ wear behavior. The results reveal that las

Abstract:

Isotropic pyrolytic graphite is a kind of graphite material. Because of its excellent performance, it is gradually used in aero-engine turbine shaft seals. But this material is a kind of brittle material, and it wears seriously during the cutting process. Through analysis of the process of cutting this material with PCD insert, the main wear region and the wear pattern at different cutting time were obtained. Using the scanning electron microscopy to observe the wear regions, the wear mechanism of PCD was obtained. At the first stage of the wear mechanisms were mainly mechanical wear and abras

Rank regression for non-parametric data revealed a weak relationship between the number of cementum lines per tooth (y), which was assumed to correspond to the age of the possums (in years), and tooth wear (males: age = 0.51x

Abstract:

ABSTRACT Tire wear performance is very important in terms of safety and economic benefit for customers and environmental conservation. Tire wear performance can be sorted into “global” or “local” wear. Local wear means uneven tire wear, for example, heel/toe wear, one-sided shoulder wear, feather edge wear, etc. This uneven wear decreases tire life locally and has the potential for causing a noise problem, so it is very important to improve uneven wear performance for long life tire. It is difficult to correctly evaluate the uneven tire wear performance of a brand-new tire, because the tire we

Abstract Tread pattern wear is predicted by using an explicit finite element model (FEM) and compared with the indoor drum test results under a set of actual driving conditions. One pattern is used to determine the wear rate equation, which is composed of slip velocity and tangential stress under a single driving condition. Two other patterns with the same size (225/45ZR17) and profile are used to be simulated and compared with the indoor wear test results under the actual driving conditions.

The wear of a hydropower unit is generally at a minimum when operated close to best efficiency and increases when operating at higher or lower set points.

Asphalt and concrete reclamation machines are used to cut roadways when a repair is required. The performance of these machines can affect the quality of road repairs, and cost/profitability for both contractors and governments. We believe that several performance characteristics in reclamation machines are governed by the placement and pattern of cutting picks on the cutter head. Previous studies, focused on mining and excavation applications, have shown strong correlation between placement and wear.

The two-phase flow parameters (solid concentration, velocity, particulate stresses) at the wetted walls are related to the wear distribution as a function of particle dynamics, material characteristics and the presence of other surface processes such as corrosion and scaling. The probabilistic flow analysis enhances the ability to model the wear process. The approach is applicable to two- and three-dimensional problems

Due to size limitations, long lengths of straight pipe are not always practical and flow conditioners may be the only viable option.

Abstract:

In Germany identification of logistics land is done rarely, among other things due to anonymization of employment and building data. The paper at hands presents a method for identifying logistics land based on publicly available data, in order to present an image of the existing spatial structure of logistics land. Identified spatial hotspots are mostly located in Metropolises/Regiopolises and their suburbs, along highways in areas with flat relief and in vicinity to large inland teminals/inland harbours. Correlation analyses show, that the area of identified logistics land shows only weak but

Abstract:

Egypt has emerged as a key adopter and regional diffuser of digital authoritarian practices. Once limited by weak digital infrastructure, the Sisi regime has transformed the country into a technologically repressive state through sweeping legal reforms, censorship mechanisms, and expansive surveillance networks. Drawing heavily from the models of China and Russia—particularly in urban monitoring and information control—Egypt actively emulates their approaches. Crucially, both Chinese and Western technology firms have facilitated this transformation, revealing a broader pattern of global compli

Full text

Abstract:

Computable General Equilibrium (CGE) models are commonly used for global agricultural market analysis. However, concerns are sometimes raised about the quality of their output since key parameters may not be econometrically estimated and little emphasis is generally given to model assessment. This article addresses the latter issue by developing an approach to validating CGE models based on the ability to reproduce observed price volatility in agricultural markets. We show how patterns in the deviations between model predictions and validation criteria can be used to identify the weak points o

Abstract:

We investigate whether investments in renewable energy – solar and wind plants – create jobs in the municipality where they are located. Using 13 years of monthly data, we exploit the variation in the timing and size of investment projects across more than 3,200 municipalities in Spain, a country with substantial investments in this area. We use a new estimator for staggered differences-in-differences analysis that extends the local projections approach with clean controls (Dube et al., 2022). We find strong heterogeneity in the magnitude and pattern of the impacts of solar and wind investment

Abstract:

Smoking, poor diet, physical inactivity and harmful alcohol use are leading risk factors driving the UK’s high burden of preventable ill health and premature mortality. All are socioeconomically patterned and contribute significantly to widening health inequalities. This Health Foundation report summarises recent trends for each of these risk factors and looks at national-level policies for England, introduced or proposed by the UK government between 2016 and 2021. The report reviews the government’s approach and finds a heavy reliance on policies aimed at changing individual behaviour and an
