Wu, J. (author), Li, S. (author), Fu, A. (author), Cvetkovic, M. (author), Palensky, P. (author), Vasquez, Juan C. (author), Guerrero, Josep M. (author)

The increasing proportion of renewable energy introduces both long-term and short-term uncertainty to power systems, which restricts the implementation of energy management systems (EMSs) with high dependency on accurate prediction techniques. A hierarchical online EMS (HEMS) is proposed in this paper to economically operate the Hybrid...

The first mile towards access equity: Is on-demand microtransit a valuable addition to the transportation mix in suburban communities?

Liezenga, A. M. (author), Verma, T. (author), Mayaud, J. R. (author), Aydin, N.Y. (author), van Wee, G.P. (author)

As cities grow, the benefits of living in them are increasingly unequally distributed. USA cities, in particular, have experienced rapid suburbanization of poverty and decreased levels of access to jobs for transit-dependent and vulnerable communities. The public transit challenges in suburbs call for innovative forms of transit to turn the...

Simulation–optimization configurations for real-time decision-making in fugitive interception

van Droffelaar, I.S. (author), Kwakkel, J.H. (author), Mense, Jelte P. (author), Verbraeck, A. (author)

Simulation–optimization models are well-suited for real-time decision-support to the control room for search and interception of fugitives by Police on a road network, due to their ability to encode complex behavior while still optimizing the interception. The typical simulation–optimization configuration is simulation model optimization,...

Vector-flow imaging of slowly moving ex vivo blood with photoacoustics and pulse-echo ultrasound

Smith, Caitlin (author), Shepherd, Jami (author), Renaud, G.G.J. (author), van Wijk, Kasper (author)

We present a technique called photoacoustic vector-flow (PAVF) to quantify the speed and direction of flowing optical absorbers at each pixel from acoustic-resolution PA images. By varying the receiving angle at each pixel in post-processing, we obtain multiple estimates of the phase difference between consecutive frames. These are used to...

Electrochemical CO₂ reduction on a copper foam electrode at elevated pressures

Girichandran, N. (author), Saedy, S. (author), Kortlever, R. (author)

Electrochemical CO₂ reduction is a promising way of closing the carbon cycle while synthesizing useful commodity chemicals and fuels. One of the possible routes to scale up the process is CO₂ reduction at elevated pressure, as this is a way to increase the concentration of poorly soluble CO₂ in aqueous systems...

Artificial Biocatalysis: Quo Vadis?

Ingram, A.A. (author), Oike, K. (author)

Astonishing progress has been achieved in unlocking new-to-nature biocatalysis in the past decades. The progress in protein engineering enabled research to efficiently incorporate artificial structural elements into enzyme design. Recent trends include cofactor mimetics, artificial metalloenzymes and non-canonical amino acids. In this...

On mixtures as working fluids of air-cooled ORC bottoming power plants of gas turbines

Krempus, D. (author), Bahamonde, Sebastian (author), van der Stelt, T.P. (author), Klink, Wolfgang (author), Colonna, Piero (author), de Servi, C.M. (author)

The use of mixtures as working fluids of organic Rankine cycle (ORC) waste heat recovery (WHR) power plants has been proposed in the past to improve the matching between the temperature profile of the hot and the cold streams of condensers and evaporators, thus to possibly increase the energy conversion efficiency of the system. The goal of...

Utilization of synthetic system intelligence as a new industrial asset

Horvath, I. (author)

System knowledge and reasoning mechanisms are essential means for intellectualization of cyber-physical systems (CPSs). As enablers of system intelligence, they make such systems able to solve application problems and to maintain their efficient operation. Normally, system intelligence has a human-created initial part and a system-produced ...

Assessing the influence of street canyon shape on aircraft noise: Results from measurements in courtyards near Amsterdam Schiphol Airport

Lugten, Martijn (author), Wuite, F.G.E. (author), Peng, Zhikai (author), Tenpierik, M.J. (author)

Aircraft noise is a major stressor for communities in the vicinity of airports. Aircraft noise prediction models omit the built environment, based on an implicit assumption that the impact of buildings on the propagation of aircraft noise is neglectable. In this article a study is presented in which aircraft noise levels were measured near...

Flow patterns in ascending aortic aneurysms: Determining the role of hypertension using phase contrast magnetic resonance and computational fluid dynamics

Ramaekers, M. J.F.G. (author), van der Vlugt, I.B. (author), Westenberg, J. J.M. (author), Perinajová, R. (author), Lamb, H. J. (author), Wildberger, J. E. (author), Kenjeres, S. (author), Schalla, S. (author)

Thoracic aortic aneurysm (TAA) is a local dilation of the thoracic aorta. Although universally used, aneurysm diameter alone is a poor predictor of major complications such as rupture. There is a need for better biomarkers for risk assessment that also reflect the aberrant flow patterns found in TAAs. Furthermore, hypertension is often...

Fabrication of low thermal expansion Fe–Ni alloys by in-situ alloying using twin-wire arc additive manufacturing

Sood, A. (author), Schimmel, Jim (author), Bosman, Marko (author), Goulas, Constantinos (author), Popovich, V. (author), Hermans, M.J.M. (author)

The binary Fe–Ni system offers alloys with notably low linear coefficients of thermal expansion (CTE), contingent upon their Ni content. In this respect twin-wire arc additive manufacturing (T-WAAM) presents the opportunity of in-situ alloying through the simultaneous feeding of two metal wires into a weld pool to obtain desired alloy...

Towards Structural and Aeroelastic Similarity in Scaled Wing Models: Development of an Aeroelastic Optimization Framework

Filippou, E. (author), Kilimtzidis, Spyridon (author), Kotzakolios, Athanasios (author), Kostopoulos, Vassilis (author)

The pursuit of more efficient transport has led engineers to develop a wide variety of aircraft configurations with the aim of reducing fuel consumption and emissions. However, these innovative designs introduce significant aeroelastic couplings that can potentially lead to structural failure. Consequently, aeroelastic analysis and...

Fractional periodic boundary value and Cauchy problems with Hilfer–Prabhakar operator

Marynets, K. (author), Tomovski, Živorad (author)

We introduce a successive approximations method to study one fractional periodic boundary value problem of the Hilfer-Prabhakar type. The problem is associated to the corresponding Cauchy problem, whose solution depends on an unknown initial value. To find this value we numerically solve the so-called ’determining system’ of algebraic or...
