Effective elastic properties of two -dimensional solids with inhomogeneities of irregular shapes
… solids with inhomogeneities of various shapes. We develop a special procedure to evaluate the contribution of irregularly shaped inhomogeneities to these properties. The method can also be used to investigate the stress concentrations around the inhomogeneities. The procedure is based on …

Investigating expert bias toward statistical group feedback in the Delphi Technique
… the e-Delphi experiment was to estimate areas of irregular shapes by a panel of participants who had more than sufficient expertise in the subject matter - in this case background in mathematics - to reach reasonable responses. It was demonstrated that most of the participants had a tendency to …

Transport of soft materials in crowded environment
… information from images of macromolecules with irregular shapes and heterogeneous transportation dynamics. Systems studied are actively transported endosomes in living cells, and diffusing semi-flexible polymer chains in rigid networks. By going beyond traditional particle tracking and …

A New Generation of Idealized Protein Building Blocks Enables Rational Nanomaterial Design
… nanomaterials has been difficult due to the irregular shapes and behaviors of naturally-evolved proteins. Even when new protein complexes can be modeled, it remains a challenge to assign sequences to the models for them to form correctly when expressed. In this work, we have made a new …

Smoothness analysis of subdivision algorithms
… algorithms are common tools for smoothing down irregularly shaped meshes. Of special interest, due to their simple formulations, are algorithms that generalize B-spline subdivision. Their conceptual simplicity is in stark contrast to the complexity of analysing their results. A complete formal …

Experimental determination of the buckling for unusual geometrical shapes using paraffin
… duration was injected into regular paraffin shapes (cylinders with diameter and height ratio equal approximately to one). An empirical curve of decay constant of the neutron population versus the buckling was obtained. The measured decay constant, λ, was fitted by the method of least square …

Tension-induced tunable corrugation in two-phase soft composites and its properties as a band gap structure
… lead to the formation of membrane channels with shapes and sizes tunable by the level of stretch and enable the interfaces to progressively soften and evolve into non-planar geometries characterized by the nucleation and stable growth of interfacial channels of irregular shapes. It is also …

Object tracking and fetal signal monitoring
… problem extremely challenging. Examples include, irregular shapes, intensity variations, color variations, speckle noise, obstacles, and background complexity. The new method developed combines the advantages of pyramid Lucas-Kanade (PLK) optical flow and optimal recursive Bayesian filters for …

A study on chemical stabilization of Oil Sands Mature Fine Tailings
… grouts, gelling products with undulating and irregular shapes serve as cementation agent. The XRD analysis of MFT shows that clay minerals’ peak intensities in XRD patterns reduce after chemical stabilization. The results also indicate the additional C-S-H peaks in cement-MFT mixtures but show …

Linear and non-linear mechanistic modeling and simulation of the formation of carbon adsorbents
… to the discrete nature, mesoscopic sizes, and irregular shapes of the substrates utilized as well as to their intricate internal surface configuration. Moreover, any process of carbon-adsorbent formation may fluctuate increasingly severely with time. It is desirable that such a process …

The post-dehydration processing and the effects on the structural modifications and functionalities of milk protein powders
… MPI agglomerated by FB had the more irregular shapes and porous structures. However, densely packed structures of HS granules caused the higher bulk density and lower porosity. Their shapes were more like spheres with smoother surfaces. FB agglomeration significantly improved the …

Development of an MR-compatible SPECT system based on energy resolved photon counting detectors
… and calibration method that accounts for the irregular shapes and physical details in the collimation apertures. Besides this, a detailed charge collection inside strong magnetic field is developed by J.W Tan in our group, and a MR correction model based on this model is used to reconstruct …

Synthetic ground truth of biological shapes — Simulating variable Nuclear Pore Complexes for Microscopy
… such as varying diameters, elongated shapes, 9-fold symmetry, and irregular shapes, evidence a high degree of divergence from this average. Single Molecule Localization Microscopy (SMLM) images NPCs at protein-level resolution, whereupon image analysis methods study NPC variability. …

Particle Sensing in Gas Turbine Inlets Using Optical Measurements and Machine Learning
… errors for measuring particles with complex and irregular shapes, such as sand, volcanic ash, and ice crystals. The light-particle interaction contains information on the desired parameters, such as particle shape and size. The research presented in this dissertation uses this idea for a novel …

The geochemistry and petrogenesis of the Saltpeterkop carbonatite complex near Sutherland, Northern Cape, South Africa
… numerous shallow intrusions (dykes, sills and irregular shapes), satellite breccia pipes and pipe-shaped intrusions that host fresh to only moderately altered igneous rocks. The main igneous rock types include (in decreasing order of abundance): carbonatite, potassic trachyte, olivine …

Dynamic behaviour of curved cable-stayed bridges
… typically showed to several special geometric shapes, which lead to a different dynamic ability. Therefore, in order to verify the dynamic performance of the structure, it is necessary to investigate the effects on dynamic behaviour of such particular geometric shape and structure by …

Dose Calculation For Electron Therapy
… the patient. The dosimetry of only regular field shapes (circular, square, or rectangular) is well developed. However, most tumors have irregular shapes and their dosimetry is calculated by direct measurement. This is laborious and time consuming. In addition, error can be introduced during …

THE EFFECTS OF FEED PROCESSING ON THE FORMATION OF STARCH DAMAGE IN SOFT AND HARD WHEAT AND ITS IMPACT ON STARCH DIGESTIBILITY AND APPARENT METABOLIZABLE ENERGY IN BROILER CHICKENS
… after grinding the endosperm of hard durum had irregular shapes and the starch granules appeared to have evidence of fractures but they remained mostly embedded in the endosperm matrix. In contrast, the starch granules in soft durum wheat appeared to have smoother edges and the starch granules …
