Inspired by carangiform fish with a high-aspect ratio of the caudal fin?s up-down swing, but also by dolphins with a similar caudal fin?s left-right swing, a robotic fish with a spatial oscillating rigid caudal fin is implemented to optimize propulsion a...

Solid oxide fuel cell systems such as those presented in this paper are not only applicable for a pure supply with electric energy, they can typically also be used in decentralized power stations, i.e., as micro-cogeneration systems for houses, where bot...

A curved riparian zone can create highly complex flow patterns that have a great effect on erosion, pollutant transport, surface water-groundwater exchange and habitat qualities. The small-disturbance theory has been applied to derive the analytical solu...

Spur dikes are river protection structures typically used for flow diversion from erodible banks. However, scouring might be a severe problem that compromises their stability and, consequently, their hydraulic function. This paper aims to study the maxim...

The Jump Point Search (JPS) algorithm ignores the possibility of any-angle walking, so the paths found by the JPS algorithm under the discrete grid map still have a gap with the real paths. To address the above problems, this paper improves the path opti...

In this work, we consider the problem of calculating the generalized Moore?Penrose inverse, which is essential in many applications of graph theory. We propose an algorithm for the massively parallel systems based on the recursive algorithm for the gener...

We employ as a speeding-accident rate index the probability of an accident caused by speeding on a curved expressway. This is defined as the probability that the actual speed of a car entering a curve exceeds the maximum safe speed of the curve in accord...

Airworthiness certification requires proof of structure strength, which is performed generally through a building block approach. To achieve this, representative intermediate-scale experiments generated by test benches are, in general, needed, in additio...
