The Hierarchical Drift Diffusion Model (HDDM) was used to quantify decision-making mechanisms recruited by the task, to determine if any such mechanism was disrupted by depression. Methods: Data came from two samples (Study 1: 258 MDD, 36 controls; Study 2: 23 MDD, 25 controls). On each trial, participants indicated which of two similar stimuli ...

Consequently, we apply a Drucker-Prager rheology model (Table 2), the ANEOS for dunite, and the ε − α porosity compaction model with a porosity of 42% ( Table 2), using parameters for regolith ...

Grain kernels are subject to a combination of compression, impact, and friction loads during agricultural production [1].The level of grain kernel damage is greatly affected by various physical and mechanical properties of the grain such as moisture content, shape, size, and damage resistance [2].Damage resistance is defined as the ability of grain to withstand …

Optimizing blasting parameters is a crucial and challenging aspect for mines to enhance production efficiency and ensure safe operations. Effectively controlling the distribution density of explosive loading in blastholes is equally vital for achieving optimal blasting results and safeguarding the brow line. This study focuses on the ore recovery blasting in fractured rock …

A physical model of dart impact tests of film manufactured from semi‐crystalline polyethylene resins is developed. The models treat the dart impact tests as a special case of the standard high ...

Hi, it's really a great feature that computations are saved on shapediver. But, one of my models first timed out for a certain parameter set and later was broken (one brep …

Measuring Uncertainty and Its Impact on the Economy Andrea Carriero, Todd E. Clark, and Massimiliano Marcellino We propose a new model for measuring uncertainty and its effects on the economy, based on a large vector autoregression with stochastic volatility driven by common factors representing macroeconomic and fi nancial uncertainty. The

Nowadays, electrical machines and drive systems are used in numerous domestic and industrial applications. Due to this fact, unexpected failures can lead to fatal consequences and are to be prevented.

A further two articles focussing on extraversion and reward-processing employ computational models of reward learning: Pickering and Pesola identify a number of specific parameters within biologically-plausible models of reward learning that potentially represent the neural substrates of traits such as extraversion (e.g., those that modulate ...

A C++ program was specifically developed to track the 3D trajectory of blocks and fragments, and measure velocities before and after the impact. Two different modules were implemented, one for the blocks that break and one for those that do not. The trajectory of a non-fragmented block is obtained by comparing it to its 3D model.

Guerreiro et al. [6] showed that the impact between main structures and retaining blocks can inevitably affect superstructure's response accelerations. Matsagar et al. [7] studied the effects of different collision parameters on the impact response of base-isolated structures, including the type of isolation structure, the natural period of vibration, number of stories, and …

The successful validation of Vogel and Peukert model incorporating the effect of impact number demonstrates its versatility whilst other key parameters such as impact energy …

A coupled constitutive model of viscoplasticity and ductile damage for penetration and impact related problems has been formulated and implemented in the explicit finite element code LS-DYNA.

The ISIMIP3a impact model simulations driven by these observation-based climate-related and direct human forcings are designed to test to what degree the impact models can explain observed changes in natural and human systems. In a second set of ISIMIP3a experiments the participating impact models are forced by the same DHFs but a ...

The breakage probability is generally used to describe the fraction of particles which are broken in the impact event (Vogel and Peukert, 2003). ... Once model parameters are calibrated through the uniaxial compressive tests, the predictive accuracy of DEM bonded contact model can be assured by extending its application to the other stressing ...

They also varied the discount rate and time frame of analysis. Probabilistic sensitivity analyses were performed to estimate the impact of parameter uncertainty. In their example, model and methodological choice had a profound effect on estimated cost-effectiveness, but parameter uncertainty played a relatively minor role.

These validated model parameters are used to predict composite damage and resistance behavior of composite structures made from plain-weave plain weave S-2 glass/SC15 …

Fortified rice kernels (FRK) have emerged as innovative fortified product containing essential minerals and vitamins. Broken rice flour and micronutrient premix containing iron, folic acid and vitamin B 12 were used to prepare FRK using a pilot scale twin screw extruder (TSE). Effect of extrusion parameters such as die head temperature (70–110 °C), extruder screw …

Cell survival was calculated based on the linear quadratic-linear model and the radiosensitivity related parameters were adjusted in 1 Gy increments of the administered dose. The model reproduced published experimental data that were obtained with different cell lines and oxygen concentrations, and was used to analyze the impact of parameter ...

tosis deconvolution (MCKD) to enhance its impact characteristics. The results show that the phase between the fault impact and its adjacent meshing impact is consistent with the pro-posed assisted phase. Finally, the correctness of the vibration mechanism and the improved phenomenological model are verified experimentally. 1. Introduction

Statistical uncertainties, arising from the uncertainty of parameter estimation and model selection, are often neglected in probabilistic assessment of engineering structures.

2.1 Transient unloading model under in-situ stress. When excavating a circular tunnel at a large depth in rock mass, the in-situ stress is uniformly distributed. To simplify the analysis, taking the excavation radius of a blast-formed tunnel as an example, the problem of uniform tunnel excavation is regarded as a plane strain problem, radical stress is …

The scale-up of wet granulation processes is commonly divided into two categories: engineering and attribute-based methods. An engineering-based scale-up approach is a strategy based on dimensional analysis and an attribute-based supported on the principles of "equifinality", where process variables are adjusted to obtain equivalent granule attributes.

The effects of impact velocity and bond strength on the evolution of the force exerted on the wall, the kinetic energy of the agglomerate and the proportion of bonds broken were demonstrated. Similar application has been presented by Khanal et al. [27]. This model is capable of describing well breakage of quasi-brittle materials, that is ...
