IFS (Iterated Function Systems) is a method to model fractal object based on affine transformation functions. The star-like object rotation effect in the IFS fractal model could be exhibited by using metamorphical method, as a replacement to the affine ro... see more

Since Thailand successfully launched the first earth observation satellite (Thaichote) in 2008, the Geo-Informatics and Space Technology Development Agency (GISTDA) has started developing an orbit analysis tool called “EMERALD” to be used for the current ... see more

Using the theory developed by one of the authors in a  previous paper, the authors discuss and present solutions for the low thrust orbital transfer in a large number of applications of practical interest:Telecommunication missions from the Geostatio... see more

For decades, researchers have investigated the phenomenon of vibrations in drilling activities. One of the interesting things is the vibration in the drillstring. Vibration might be caused by Interfere with each other between the drilling mud and drilling... see more

The theorem of mirror trajectories, proven almost six decades ago by Miele, states that for a given path in the restrictedproblem of three bodies (with primaries in mutual circular orbits) there exists a mirror trajectory (in two dimensions) andthree mirr... see more

The MISTRAL Satellite Program, conceived in the context of the new founded Aerospace District of Campania Region (DAC), is here presented. This satellite is a 20-30 kg class spacecraft provided with a deployable flexible aero-brake shield suitable to deor... see more

In this paper, we use differential evolution (DE), with best-evolved results refined using a Nelder–Mead optimization, to solve boundary-value complex problems in orbital mechanics relevant to low Earth orbits (LEO). A class of Lambert-type problems is ex... see more

Developing technology can facilitate work activities, one of which is technology in the field of robotics. One of the purposes of creating the robot was to assist in investigating suspected targets. The target can be a gas source leak object. On the other... see more

There have been many developments of wheelchairs as mobility aids, including electric wheelchairs. Wheelchairs sometimes still require manual steering. Therefore, in this research, a smart wheelchair is developed that can move automatically to the destina... see more
