The aim of the present study was to analyze the microstructure of hydroxyapatite/alginate S.duplicatum composite scaffolds using alginate with different viscosity. The viscosity of the alginate obtained from the macroalgae S.duplicatum of Banten Indonesia and from a commercially available alginate were determined using a viscometer. Hydroxyapatite and alginates were blended, resulting gels that were...
In biodegradable polymer nanocomposite, the important factors to determine its properties are polymer, biodegradable materials and nano filler. In case of nano filler of organo layer silicate (OLS) the interlayer gallery also plays an important role. This research is intended to study the effect of surfactants to the interlayer of OLS by sonication. Glycerol monostearate (GMS) and gum rosin (GR) were...
Recently, unsaturated polyester resin (UPR) and silica nanocomposite prepared by mechanical process is the one of the promising composite materials. In this study, the effects of silica as filler on mechanical, thermal, and morphological properties of unsaturated polyester-based composite were investigated. Mechanical properties such as tensile strength, elongation and Young's modulus increase with...
Communication network expansion technology using autonomous robot introduces three research fields which is network expansion, network routing, and localization. On this research, we tried to develop an efficient robot formation and network expansion that is implemented using Open Dynamics Engine (ODE) library and network routing algorithm. This paper also shows some modifications that have been done...
Communication network expansion technology using autonomous robot covers three research fields which includes network expansion, network routing, and localization. On this research, we implement an efficient robot formation and network expansion algorithm on a simulator based on Open Dynamics Engine (ODE) library. We extended the robot formation algorithm to handle multiple sources implementation...
