Water properties critical to our understanding and managing of freshwater systems change rapidly with depth. This work presents an Unmanned Aerial Vehicle (UAV) based method of keeping a passive, cable-suspended sensor payload at a precise depth, with 95% of submerged sensor readings within ±8.4 cm of the target depth, helping dramatically increase the spatiotemporal resolution of water science...

The spin polarization of Sb overlayers on the semi-Heusler alloy NiMnSb is investigated in terms of the Landau-Ginzburg approach. The half-metallic semi-Heusler alloy NiMnSb acts as a ferromagnetic perturbation and induces a spin polarization in the semimetallic Sb overlayer. Using a Gaussian approximation, the propagation of the spin perturbation in the overlayer is calculated. The results are...

Amodel is proposed for describing the penetration of a monolithic semi-infinite and finite FRP laminates struck transversely by a rigid projectile with an arbitrary 3-D shape. Relationships for calculating the characteristics of penetration and perforation (ballistic limit velocity, depth of penetration, etc.) are derived. It is showed that some typical problems of optimization of the shape of ...

Semi-aquatic mammals have secondarily returned to the aquatic environment, although they spend a major part of their life operating in air. Moving both on land, as well as in, and under water is challenging because such species are considered to be imperfectly adapted to both environments. We deployed accelerometers combined with a depth sensor to study the diving behavior of 12 free-living Eur...

The distribution of center self-embeddings and extrapositions in German is assumed to reflect a universal performance strategy of minimizing memory load during parsing. Self-embedded relative clauses of embedding depth 2 were semi-automatically analysed in a treebank of German newspaper texts. Clause length and especially extraposition distance are found as the main distinctive parameters betwe...

In this paper, we discuss our experimental results on Simulator Sickness (SS). A series of experiments were conducted in our Virtual Reality (VR) Lab. Our aim was to investigate the correlations between the perception of depth and the feeling of discomfort, as well as the role of gameplay regarding the familiarity of the viewer with computer games in the feeling of discomfort. Participants were...

This paper describes an in-depth usability evaluation of our RoadMAProad network extraction system. Six operators used RoadMAP in both manual and semi-automated modes, as well as BAE Systems’ SOCET SET, to extract roads in four image test areas. An in-depth statistical analysis was performed on the timing results, with the main conclusion being that the performance differences among the three...

This paper presents an in-situ inspection and experimental investigation on the pore solution pH of concrete cover for the corrosion initiation of rebars under a long-term natural carbonation reaction. A 77-year-old steel mill was inspected, and 35 concrete column cover samples were collected to test the pH of the pore solution and phase compositions layer by layer. The variation in pH and phas...

A semi-empirical model for surf zone wave height decay is adapted to the parabolic equation method in order to include the effect of depth-limited wave breaking in combined refraction/diffraction calculations. Several examples for plane beaches are presented in order to show correspondence between the empirical model, its numerical formulation, and previous laboratory data. The model is then ap...
