Improving the earthquake resistance of a building on flexible supports with foundations for the conditions of the city of Almaty

This article describes the methods of strengthening foundations on flexible supports, such as pendulum, lead cores, damping connection, a design solution with switching connections, a seismic «invisibility cloak», which includes the creation of a cloak of 100 concentric plastic and concrete rings.

Chiral Plasmonic Liquid Crystal Gold Nanoparticles: Self-Assembly into Circular Dichroism Responsive Helical Lamellar Superstructure

Owing to their proven and potential promises in various technological endeavors ranging from catalysis and sensing to invisibility cloak made from metamaterials, chiral plasmonic superstructures resulting from the directed self-assembly...

Invisibility Cloak using Color Detection and Segmentation with open CV

Have you ever thought of making visible things invisible, just like the Harry Potter? Have you ever thought how does one supersede backgrounds and add effects in a movie? The cloak was magical and invisible in Harry Potter, the movie. As we know there is no magic and no invisible cloak which exists in the world. It’s all about the graphicstricks. The concept of an invisibility cloak is a mixture of science, fantasy, and the collective imagination. This paper helps to create one’s own ‘Invisibility Cloak’.It will make use of Python and OpenCV module specifically targeting Image Processing and Image Segmentation to create a false sense of invisibility in the frame. It will explore how an object of a specific color or texture can be manipulated using the OpenCV library of python. To achieve this, initially we’ll be capturing and storing the backdrop frame . Thereafter we’ll be identifying the red coloured fabric by making use of the above mentioned algorithms. Then we’ll segment out the red colored fabric by generating a mask and then finallywe’ll generate the final augmented(magical) output to create Invisibility cloak. These steps are discussed deeper in thepaper.
