Analyzing the rent-to-price ratio for the housing market at the micro-spatial scale
International Journal of Strategic Property Management, 2018 The rent-to-price ratio is one of the popular indicators for monitoring the property market. This study explores micro-scale spatial dynamics of the ratio for houses at the individual property level in Seoul, South Korea. We match the apartment unit sold

An estimation method of full scale performance for pulling type podded propellers
International Journal of Naval Architecture and Ocean Engineering, 2014 This paper presents a new estimation method of full scale propulsive performance for the pulling type podded propeller. In order to estimate the drag of pod housing, a drag velocity ratio, which includes the effects of podded propeller loading and ...

Large-scale age-dependent skewed sex ratio in a sexually dimorphic avian scavenger. [PDF]
PLoS ONE, 2012 Age-dependent skewed sex ratios have been observed in bird populations, with adult males generally outnumbering females. This trend is mainly driven by higher female mortality, sometimes associated with anthropogenic factors.

The Scale Effect Study on the Transient Fluid–Structure Coupling Performance of Composite Propellers
Journal of Marine Science and Engineering, 2022 In order to predict the fluid–structure coupling performance of a full-scale composite propeller under a wake flow field behind a full ship, a bidirectional transient fluid–structure coupling algorithm was established.

On Supersymmetric Multipole Ratios [PDF]
, 2022 Four-dimensional supersymmetric black holes are static and so have all vanishing multipoles. Nevertheless, it is possible to define finite multipole ratios for these black holes, by taking the ratio of (finite) multipoles of supersymmetric multicentered geometries and then taking the black hole scaling limit of the multipole ratios within these ...

Oscillatory large-scale circulation in liquid-metal thermal convection and its structural unit [PDF]
Journal of Fluid Mechanics, 977 (2023), A16, 2023 In Rayleigh-B\'enard convection (RBC), the size of a flow domain and its aspect ratio $\varGamma$ (a ratio between the spatial length and height of the domain) affect the shape of the large-scale circulation (LSC). For some aspect ratios, the flow dynamics include a three-dimensional oscillatory mode known as a jump-rope vortex (JRV), however, the ...

Upper Bound on the Tensor-to-Scalar Ratio in GUT-Scale Supersymmetric Hybrid Inflation [PDF]
, 2014 We explore the upper bound on the tensor-to-scalar ratio $r$ in supersymmetric (F-term) hybrid inflation models with the gauge symmetry breaking scale set equal to the value $2.86\cdot10^{16} {\rm GeV}$, as dictated by the unification of the MSSM gauge ...

Scale-Net: Learning to Reduce Scale Differences for Large-Scale Invariant Image Matching [PDF]
arXiv, 2021 Most image matching methods perform poorly when encountering large scale changes in images. To solve this problem, firstly, we propose a scale-difference-aware image matching method (SDAIM) that reduces image scale differences before local feature extraction, via resizing both images of an image pair according to an estimated scale ratio.

Conformal Symmetry as a Template: Commensurate Scale Relations and Physics Renormalization Schemes [PDF]
, 1999 Commensurate scale relations are perturbative QCD predictions which relate observable to observable at fixed relative scale, such as the "generalized Crewther relation", which connects the Bjorken and Gross-Llewellyn Smith deep inelastic scattering sum ...
