The paper ‘Numerical shape from shading and occluding boundaries” [ I O ] proposed a method to determine the 3D shape of an object from a single brightness image using the smoothness constraint on surface orientations, and the orientations of the surface given along an occluding boundary. This paper contributed both a specific algorithm for solving a specific problem, and a general approach tha...

An independent derivation of solutions to the Camassa-Holm equation in terms of multi-dimensional theta functions is presented using an approach based on Fay’s identities. Reality and smoothness conditions are studied for these solutions from the point of view of the topology of the underlying real hyperelliptic surface. The solutions are studied numerically for concrete examples, also in the l...

We propose a new approach to appearance based place recognition from metric 3D maps, exploiting the NDT surface representation. Locations are described with feature histograms based on surface orientation and smoothness, and loop closure can be detected by matching feature histograms. We also present a quantitative performance evaluation using two real-world data sets, one of which is highly se...

This paper introduces and proves new concept of salt dissolving in water as very tiny solid sodium chloride particles of nanovolumes, from this point of view salt water can be desalinated by collision with special surface characterized by smoothness upon nano level, high rigidity, high hardness under appropriate conditions of water launching in the form of thin laminar flow under suitable speed...

The aim of this study is to evaluate the effect of meat content and surface smoothness on the deactivation of Listeria monocytogenes in beef-agar food models achieved by shortwave ultraviolet (UVC) light. Food models with various meat contents were made using chopped beef slices and agar solution. Prepared models together with a Listeria selective agar (LSA) plate and a slice of cooked beef wer...

Regularization o ers a powerful framework for signal recon struction by enforcing weak constraints through the use of stabilizers Stabilizers are functionals measuring the degree of smoothness of a sur face The nature of those functionals constrains the properties of the reconstructed signal In this paper we rst analyze the invariance of stabilizers with respect to size transformation and their...

In the present research, free convection heat transfer from isothermal concave and convex body shapes is studied numerically. The body shapes investigated here, are bi-sphere, cylinder, prolate and cylinder with hemispherical ends; besides, they have the same height over width (H/D = 2). A Numerical simulation is implemented to obtain heat transfer and fluid flow from all of the geometries in a...

Let ` ∈ −∞. It has long been known that every prime is Thompson [17, 17]. We show that there exists a Ω-holomorphic Clifford scalar. A useful survey of the subject can be found in [17, 14]. Next, this could shed important light on a conjecture of Pólya.

A new surface profiling algorithm called the local model fitting (LMF) method is proposed. LMF is a single-shot method that employs only a single image, so it is fast and robust against vibration. LMF does not require a conventional assumption of smoothness of the target surface in a band-limit sense, but we instead assume that the target surface is locally constant. This enables us to recover ...

this paper presents an improved method for generating a hybrid Catmull-Clark subdivision surface that can interpolate an arbitrarily intersecting network of curves. Compared with our most recent work on this topic, the surface generation process is now simpler and altogether more intuitively appealing. Secondly, this method reduces to a bare minimum the set of constraints the surface requires t...
