We present results of coupled direct numerical simulations between flow and a deformable bed in a horizontally periodic, turbulent open channel at a shear Reynolds number of Reτ = 180. The feedback between the temporally ...
We present results on the formation of ripples from linear stability analysis. The analysis is coupled with direct numerical simulations of turbulent open-channel flow over a fixed sinusoidal bed. The presence of the ...
We present results from direct numerical simulation on the transition from straight‐crested to sinuous‐crested bedforms. The numerical setup is representative of turbulent open channel flow over an erodible sediment bed ...

In the 1960’s, innovative research in the former Soviet Union laid grounds for the evolution of the Sliding Mode Control (SMC). Known for its robustness and insensitivity to parameter variations, SMC immediately became an ...
Ionic Polymer Metal Composite (IPMC) is an Electo-Active Polymer (EAP) that is well-known for its actuation and sensing behavior. It has been shown that in charge sensing mode an IPMC generates one order of magnitude larger ...

A fully connected vehicular ad hoc network (VANET) establishes a strong foundation for the development of smart cities, where one of the main objectives is the improvement of the welfare of commuting passengers. The ...
A fully-connected Vehicular Ad-hoc Network (VANET) contributes tremendously to the improvement of the travel experience of commuting passengers. However, the existence of an end-to-end multi-hop path across VANET highly ...

The addition of an external communication layer to the power system has left it vulnerable to cyberattacks. False data injection (FDI) can be used to manipulate measurements that are used to estimate the state of the power ...
This paper investigates two pulse-based Optical Spatial Modulation (OSM) schemes as cost-efficient solutions for multi-aperture Free-Space Optical (FSO) communications with Intensity-Modulation and Direct-Detection (IM/DD). ...

The traffic speed deflectometer (TSD) is a device used to evaluate the pavement’s structural condition. Measurements obtained from the TSD are affected by noise, which can make it hard to interpret test results. The main ...
This paper investigates the potential changes in the geometric design elements in response to a fully autonomous vehicle fleet. When autonomous vehicles completely replace conventional vehicles, the human driver will no ...
The majority of research efforts in the field of access control of autonomous vehicles at intersections are geared towards fully connected vehicles. The underlying assumptions for such efforts are active vehicle-to-vehicle ...

Ionomeric polymer transducer (IPT) is an electroactive polymer that has received considerable attention due to its ability to generate large bending strain (>5%) and moderate stress at low applied voltages (±2 V). Ionic ...
Ground instability, such as roof or rib failures, is one of the most serious and frequent safety hazards that occur in underground mining, tunneling, and underground construction. The ground-related parameters and features ...
Accessing visual information becomes a central need for all kinds of tasks and users (from accessing graphics and charts in news articles, to viewing images of items on sale on e-commerce sites), especially for blind users. ...
The Urban Heat Island phenomenon and urban overheating are serious consequences of urbanization resulting in impacts on thermal comfort levels, heat stress and even mortality. This paper builds on previous findings on the ...
