Fiber-optic sensing is a field that is developing at a fast pace. Novel fiber-optic sensor designs and sensing principles constantly open doors for new opportunities. In this paper, we review a fiber-optic sensing technique developed in our research group called frequency-shifted interferometry (FSI). This technique uses a continuous-wave light source, an optical frequency shifter, and a slow d...

Abstract The measurement of societal wellbeing has moved beyond gross domestic product and emerged as an important factor within the paradigm holistic sustainability assessment, including agricultural sustainability. At this juncture, knowledge gaps exist between policy priorities data infrastructure to evaluate social issues, particularly regarding farmer This study aims address gap through de...

Discriminant indicators with generalized inversion symmetry are computed only from data at the high-symmetry points. They allow a systematic search for exceptional In this paper, we propose discriminant two- and three-dimensional systems $n$-fold rotational ($n=4$, $6$). As is case symmetry, indicator taking nontrivial value predicts emergence of points loops without ambiguity reference energy....

A forest vulnerability index based on drought and high temperatures" (2016). USDA Forest Service / UNL Faculty Publications. 321. a b s t r a c t a r t i c l e i n f o Increasing forest stress and tree mortality has been directly linked to combinations of drought and high temperatures. The climatic changes expected during the next decades – large increases in mean temperature, increased heat wa...

The icosahedral quasicrystals of five-fold symmetry in two, three, and four dimensions are related to the corresponding regular polytopes exhibiting five-fold symmetry, namely the regular pentagon (H2 reflection group), the regular icosahedron 3,5 (H3 reflection group), and the regular four-dimensional polytope 3,3,5 (H4 reflection group). These quasicrystals exhibiting five-fold symmetry can b...

Square triangle tilings are relevant models for quasicrystals. We introduce a new self-similar tile-substitution which yields the well-known nonperiodic square triangle tilings of Schlottmann. It is shown that the new tilings are locally derivable from Schlottmann’s, but not vice versa, and that they are mutually locally derivable with the undecorated square triangle tilings. Furthermore, the r...

We investigate the reactions D(e, ep)n and D(~e, ep)n at GeV energies and discuss the opportunities to distinguish between different models for the nuclear ground state by measuring the response functions. In calculating the final-state interaction (FSI) we employ Glauber theory, and we also include relativistic effects in the electromagnetic current. We include not only the central FSI, but al...

We propose Finger-Specific Interaction (FSI) as a potential interaction technique for interactive surfaces. FSI treats each finger as completely independent, as one input primitive. This paper discusses the advantages and drawbacks of adopting FSI for use on interactive surfaces. The advantages include an increase of input primitives, enabling eyes-free interaction and the ability to differenti...
