While an exact definition of texture is somewhat elusive, texture can be qualitatively described as a distribution of color, albedo or local normal on a surface. In the literature, the word texture is often used to describe a color or albedo variation on a smooth surface. We refer to such texture as 2D texture. In real world scenes, texture is often due to surface height variations and can be t...

Thermal infrared (TIR) images of the building hull are often used for detecting damaged and weak spots in the insulation of the building hull. However, imaging and manually analysing each face is very time consuming. This process can be carried out more efficiently using a mobile mapping system (MMS) equipped with a TIR video camera. Frontal façades of the buildings which are visible from stree...

in this paper, a higher order continuum model is presented based on the cosserat continuum theory in 3d numerical simulation of shear band localization. as the classical continuum models suffer from the pathological mesh-dependence in strain softening models, the governing equations are regularized by adding the rotational degrees-of-freedom to conventional degrees-of-freedom. the fundamental r...

PURPOSE The superior image quality of 3 tesla (3T) magnetic resonance (MR) imaging in cervical cancer offers the potential to use a single image set for brachytherapy. This study aimed to determine a suitable single sequence for contouring tumour and organs at risk, applicator reconstruction, and treatment planning. MATERIAL AND METHODS A 3T (Skyra, Siemens Healthcare AG, Germany) MR imaging ...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

The territorial data acquisition technologies vary second of the final product scale use. So it can be passed that the classical topographical survey or terrestrial laser scanners survey for engineering works, up to the satellite images multispectral analysis for regional scale and over.The classical aerial photogrammetry and LiDAR have a territory nadir (straight-down) vision, however, in many...

Abstract. We present a phase-field model of fracture in ferroelectric single crystals for the simulation of conducting crack propagation under purely electrical loading. This is done by introducing the electrical enthalpy of a diffuse conducting layer into the phase-field formulation. Simulation results show an oblique crack propagation and crack branching from a conducting notch in a ferroelec...

In the pursuit of efficiency there is continued and developing interest in the subject of winglets and novel designs such as Blended Wing Body and Oblique Flying Wing. Winglets may exist in many modes, ranging from endplates, through folded wing tips to complex upper and lower surface partial chord devices. We have developed a design process that is directly applicable to the design of wings an...

We report that the classical phenomenon of optical activity, which is traditionally associated with chirality (helicity) of organic molecules, proteins, and inorganic structures, can be observed in artificial planar media which exhibit neither 3D nor 2D chirality. We observe the effect in the microwave and optical parts of the spectrum at oblique incidence to regular arrays of nonchiral subwave...
