In this paper, we present the design of a quadrotor vision system using a Raspberry Pi camera. The vision system of quadrotor is able to doing image process, and connecting ground control computer while autonomous flights. We developed control algorithm based on a combination of the vision system and IMU, range sensor measurements, in order to esti...

Three-dimensional (3D) open-channeled scaffolds of biopolymers are a promising candidate matrix for tissue engineering. When scaffolds have the capacity to deliver bioactive molecules the potential for tissue regeneration should be greatly enhanced. Aiming to improve the drug delivering capacity, here, we exploit 3D poly(lactic acid) (PLA) scaffold...

Nanocomposite scaffolds with tailored 3D pore configuration are promising candidates for the reconstruction of bone. Here we fabricated novel nanocomposite bone scaffolds through robocasting. Poly(caprolactone) (PCL)-hydroxyapatite (HA) slurry containing ionically modified carbon nanotubes (imCNTs) was robotic-dispensed and structured layer-by-laye...

Here we produced a novel nano-composite scaffold made of chitosan (Chit) and nanobioactive glass (nBG) retaining dual-pore structure through the robocasting technique. Robotic-dispensed composite solution (Chit with 10 wt% nBG) was rapidly solidified under a dry-ice cooled bath, which was subsequently freeze-dried. The scaffold featured the pre-des...

The surface of a synthetic biopolymer scaffold was tailored by a mineralization with calcium phosphate for use as a functional bone tissue engineering matrix. Poly(ε-caprolactone) scaffold with a defined pore configuration constructed by a robocasting method was treated in a series of solutions involving steps of surface activation and calcium phos...

Introduction: Carbon nanotubes (CNTs) have been widely recognized as new lightweight nanofillers with excellent electrical and mechanical properties. Most of all, a homogeneous dispersion of CNTs within the polymer matrix has been an issue to allow usefulness for hard tissue application. In this study, macro-channeled nanocomposites of poly(caprol...

The main sector of Mongolian economy is agricultural sector and agro-climatic condition plays an important role for effective functioning of livestock and crop industry in the sector. The main goal of this study was to determine changes in the climate in Orkhon-Selenge Basin, the Central Agricultural Region of Mongolia, specifically in air temperat...
