This article discusses the processing of signals using fast Fourier transformation in lowpower microcontrollers based on the ARM core. Simple microcontrollers do not support floating point numbers so fixed point data types must be used. Two ways of calculating FFT are analyzed: CMSIS library and special algorithm optimized for use on ARM processors (FFT-ARM). Both methods utilize a radix-4 deci...

There is a strong dynamic coupling between the base of free-floating space robot and manipulator. In order to reduce interference movement manipulator on robot's base, trajectory needs be optimized. this paper, joint path manipulators optimized by using pseudo-spectral method impact arm base. For robots, parameters identification premise planning. A proposed, which only measure base's angular s...

This paper investigates the problem of the dynamic balance control of multi-arm free-floating space robot during capturing an active object in close proximity. The position and orientation of space base will be affected during the operation of space manipulator because of the dynamics coupling between the manipulator and space base. This dynamics coupling is unique characteristics of space robo...

This paper discusses a general formulation both in kinematics and dynamics for under-actuated manipulator systems, represented by a freejoint manipulator, a free-floating manipulator, a flexible-base manipulator and a flexible-arm manipulator. We highlight the fact that a concept, originally developed for a particular system, is applicable to the others as well because the dynamic equations of ...

ARM is a a 32-bit RISC processor architecture currently being developed by the ARM corporation. The business model behind ARM is based on licensing the ARM architecture to companies that want to manufacture ARM-based CPU’s or system-on-a-chip products. The two main types of licenses are the Implementation license and the Architecture license. The Implementation license provides complete informa...

the purpose of this research was to prepare a floating matrix tablet containing domperidone as a model drug. polyethylene oxide (peo) and hydroxypropyl methylcellulose (hpmc) were evaluated for matrix-forming properties. a simplex lattice design was applied to systemically optimize the drug release profile. the amounts of peo wsr 303, hpmc k15m and sodium bicarbonate were selected as independen...
