Demarcating on-street bicycle facilities is oftenmentioned as an important strategy to encourage increased bicycle safety and bicycle travel. However, little if any literature has focused on instances where separate onstreet bicycle facilities end. This paper better understands the severity of such instances and corresponding physical characteristics. We identify 30 discontinuities of on-street...

[1] Accurate determination of parameters about seismic discontinuities in the earth, such as their depth, existence, and strength, provides critical information about the physical and chemical states and dynamics of the earth’s interior. Unfortunately, those parameters can be strongly affected by factors that are not related to the discontinuities. We use synthetic seismograms to estimate the i...

In this paper we discuss the treatment of discontinuities in Smoothed Particle Hydrodynamics (SPH) simulations. In particular we discuss the difference between integral and differential representations of the fluid equations in an SPH context and how this relates to the formulation of dissipative terms for the capture of shocks and other discontinuities. This has important implications for many...

Inaccurate depth map discontinuities are an important source of artifact and distortion in multiview systems and applications requiring depth-based view rendering such as 3DTV or free-viewpoint video. Such errors along depth discontinuities frequently occur during depth estimation and/or depth map coding. In this paper we present a novel method for correcting inaccuracies on the discontinuities...

The radiosity method is used for global illumination simulation in diffuse scenes, or as an intermediate step in other methods. Radiosity computations using Higher-Order wavelets achieve a compact representation of the illumination on many parts of the scene, but are more expensive near discontinuities, such as shadow boundaries. Other methods use a mesh, based on the set of discontinuities of ...

One method to estimate image values in the presence of noise and discontinuities is to try all possible configurations of discontinuities in a neighborhood, and then select the one that yields the best estimate according to some criterion. We call these methods multiple oriented filters since each configuration is usually a rotated and shifted version of another. Multiple oriented filters work ...

We have examined the occurrence of discontinuities in bond-breaking potential energy surfaces given by local correlation methods based on the Pulay-Saebø orbital domain approach. Our analysis focuses on three prototypical dissociating systems: the C-F bond in fluoromethane, the C-C bond in singlet, ketene, and the central C-C bond in propadienone. We find that such discontinuities do not occur ...

The pattern regulation process in amphibian limbs has been examined with respect to the presence of discontinuities in the anterior-posterior (a-p) axis. Limbs bearing such discontinuities were surgically created by contralateral exchange of either dorsal or ventral half thighs and these limbs were then amputated immediately after surgery. The results demonstrate that a-p discontinuities lead t...

The textural discontinuity hypothesis (TDH) is based on the observation that animal body mass distributions exhibit discontinuities that may reflect the texture of the landscape available for exploitation. This idea has been extended to other complex systems, hinting that the identification and quantification of discontinuities in the distributions of appropriate variables may provide clues to ...

Physical systems are by nature continuous. Perceived discontinuities in system models are in reality nonlinear behaviors that are linearized to reduce computational complexity and prevent stiffness in system analysis and behavior generation. Discontinuities arise primarily from component parameter simplification and time-scale abstraction. Discontinuities in models are handled by introducing id...
