At present, many studies have begun to focus on evaluating urban accessibility and livability, which can be a series of great guidance for future urban planning considering residents’ personal perceptions of various living aspects. It can be observed from the existing literature that urban accessibility has a mature evaluation system,...

American option pricing has been an active research area in financial engineering over the past few decades. Since no analytic closed-form solution exists, various numerical approaches have been developed. Among all proposed methods, the least square Monte Carlo(LSMC) approach is the most successful and popular. The LSMC utilizes linear...

This study aims to multiscale investigate the effects of rejuvenator type, temperature, and aging degree of bitumen on the diffusion behaviors of rejuvenators (bio-oil BO, engine-oil EO, naphthenic-oil NO, and aromatic-oil AO) in aged binders. The molecular dynamics (MD) simulation method is performed to detect the molecular-level diffusion...

Passivating contacts based on poly-Si have enabled record-high c-Si solar cell efficiencies due to their excellent surface passivation quality and carrier selectivity. The eventual existence of pinholes within the ultra-thin SiOx layer is one of the key factors for carrier collection, beside the tunneling mechanism. However, pinholes are usually...

We investigated the effect of temperature and monoethanolamine (MEA) concentration on the self-diffusivity of acid gases, CO<sub>2</sub>, and H<sub>2</sub>S in aqueous MEA solutions. For this purpose, we computed densities of pure MEA and 30 wt% MEA/water solutions while scaling the LJ energy (ϵ) parameter and point charges of MEA. Results...

We construct and analyze the Jacobi process – in mathematical biology referred to as Wright–Fisher diffusion – using a Dirichlet form. The corresponding Dirichlet space takes the form of a Sobolev space with different weights for the function itself and its derivative and can be rewritten in a canonical form for strongly local Dirichlet forms...

Oil paintings are complex, multi-layered systems that are prone to chemical degradation. While it is increasingly recognised that water plays an important role in these degradation reactions, little is known about moisture concentrations in oil paint systems and their temporal variation in response to fluctuating ambient air humidity. This...

Mo(Al<sub>x</sub>Si<sub>1-x</sub>)<sub>2</sub> alloy with x in the range of 0.35–0.65 were prepared by a one-step spark plasma sintering. To study the exclusive formation of an α-Al<sub>2</sub>O<sub>3</sub> scale, oxidation experiments were conducted in low and high oxygen partial pressure ambient at 1373 K; viz.: 10<sup>−14</sup> and 0.21...

Due to the precise lithography and highly pure silicon used in IC technology, thermal-diffusivity (TD) temperature sensors can achieve high accuracy without the need for trimming. TD sensors employ electrothermal filters (ETFs) to measure the thermal diffusivity of silicon, i.e. the rate at which heat diffuses through silicon, which is a well...

High entropy alloys (HEAs) are new potential materials for hydrogen storage applications which could help with the transition towards sustainable energy sources. The rate of hydrogen kinetics is one of the material properties that is important for the storage and other hydrogen related applications. One of the limiting factors on the rate of...

Purpose: Pre- and post-treatment MRI based Diffusion Weighted Imaging (DWI) has shown to be an effective predictor and indicator of treatment response in cancer. However, clinical applications of the Apparent Diffusion Coefficient (ADC) requires sufficient precision; this can be assessed with repeatability studies. Therefore, the purpose of this...

Delivery of biomolecules using pulsed electric fields or electrotransfer has applications such as biomedical engineering, bioprocess engineering and genomic engineering. When a cell is placed in an electric field, the induced transmembrane voltage catalyzes the formation of pores on the cell membrane. This enables the delivery of otherwise cell...

When high-temperature steels are loaded under under industrially relevant conditions not only creep (i.e. a time dependent strain increase even under nominally constant loading conditions) occurs, but also local damage is formed. At relatively short exposure times quasi-spherical micron-sized cavities form preferentially at the grain boundaries...

When attempting to enter a market, it is of the utmost importance to make a well-thought decision. Numerous academics have examined the first-mover advantage literature to determine whether entering first, second, or late is more advantageous. After many decades, there is still no consensus, and it appears that we are in a dialogue of the deaf....

This research aims to analyse the non-ohmic resistance of multiple ion-exchange membranes (IEM) in series, for a better understanding of membrane resistances. These membranes can be found in series in energy storage systems such as acid-base flow batteries (ABFB).<br/>The effect of different current densities on the ohmic and non-ohmic...

In this research, the creation, use and spread of knowledge acquired in Building with Nature pilot projects is researched, with the goal of providing recommendations to improve this use and spread in future Building with Nature pilot projects. To achieve this, a case study with the Sand Engine as the subject is performed. In addition to this, a...

High-level waste can be radiotoxic for thousands of years and should be carefully handled to prevent accidents. The research for geological disposal of radioactive waste focuses on the construction and durability of a geologic disposal facility in Dutch clays or salts. One of the challenges is assessing these host rocks’ capability to retard...

In several experiments, enzymes have shown an in increase in diffusivity in the presence of their substrate. The enhancement in diffusivity ranged from as low as 28% for urease to 80% in the case of alkaline phosphatase. There are two main competing theories. One asserts that catalytically driven boosts propel the enzyme forward in ‘leaps’,...

In the built environment, the continuous growth and expansion of urban areas worldwide have become alarming. The built environment is continuously developing in an unsustainable manner, and in the mid-term future, resources will be scarce if practices are not changed. Therefore, new building materials and methods need to be implemented to...

Microchips are made from circular silicon discs called wafers and are manufactured with photolithography. A critical step of a photolithography process is when a wafer with a photoresist is placed on a wafer table (WT) and exposed to light to form patterns that build up components of an integrated circuit (IC). The dimensions of the IC are in...
