The building façade model is the most prominent streetscape feature for rendering virtual street models. This paper aims to develop a method to identify street obstacles which hinder photo-realistic texturing of building façade. In order to achieve this, the presented method focuses on two research components. Firstly, we develop an effective grid-based line analysis method to differentiate ima...

The automatic process for texturing 3D urban environments realistically is a challenging topic in Computer Graphics, especially when the model is generated from 2D GIS data from real sites. In order to achieve realistic scenes, buildings, urban furniture and street roadways should be modeled automatically also considering the slope of steep streets. A texturing process by hand which takes into ...

nowadays, polymer blends usages increase more and more in order to produce materials with better properties. according to many research works, the blends of polyolefins have shown industrial importance. the purpose of this project was to carry out some investigations on fibers melt spun from the polypropylene and low density polyethylene blends. pp and ldpe are immiscible. pp/ldpe blend filamen...

Abstract The coronavirus (COVID-19) pandemic, especially, the transmission of virus via infected contact surfaces, has put increased emphasis on need to fabricate antimicrobial surfaces protect against various deadly pathogens. Laser surface texturing (LST), one common modification techniques, been successful for antifouling applications improve resistance bacterial adhesion. In this short revi...

The potential of ultrafast lasers (pico- to femtosecond) in orthopedics-related procedures has been studied extensively for clinical adoption. As compared conventional laser systems with continuous wave or longer pulse, provide advantages such as higher precision and minimal collateral thermal damages. Translation surgical applications the clinic restrained by limitations material removal rate ...
