Floating drug delivery system provides the advantage of sustained release of drugs over a prolonged period of time thereby maximising the oral absorption of drugs with narrow absorption window, thus, it overcomes the drawback of conventional oral drug delivery system. In situ gelling system is a novel approach in this regard. The aim of the present work was to develop an oral sustained stomach ...

Most motion control systems for mechatronic systems are implemented on digital computers. In this paper we present an FPGA based solution implemented on a low cost Xilinx Spartan III FPGA. A Production Cell setup with multiple parallel operating units is chosen as a test case. The embedded control software for this system is designed in gCSP using a reusable layered CSP based software structure...

The main objective of the present study was to develop a multiple-unit, floating-pulsatile drug delivery system for obtaining no drug release during floating and in the proximal small intestine followed by pulsed, rapid drug release in distal small intestine to achieve chronotherapeutic release of indomethacin. The system developed consists of drug containing core pellets prepared by extrusion-...

In this paper we present a general library to reason about floating-point numbers within the Coq system. Most of the results of the library are proved for an arbitrary floating-point format and an arbitrary base. A special emphasis has been put on proving properties for exact computing, i.e. computing without rounding errors.

Free-flying space robotic devices, in which manipulators are mounted on a thruster-equipped spacecraft, will assist in the construction, repair and maintenance of satellites and future space stations. Operation in a free-floating mode, in which spacecraft thrusters are turned off, increases a system’s life. The teleoperation of free-floating systems is complicated due to the dynamic coupling be...

This application note describes how to quickly implement and optimize floating-point Proportional-Integral-Derivative (PID) control algorithms specified in C/C++ code into an RTL design using Vivado HLS. You can use System Generator for DSP to easily analyze and verifiy the design. This enables floating-point algorithm designers to take advantage of high-performance, low cost, and power efficie...

Most Digital Signal Processors perform computations on integers, or fixed-point numbers, rather than floating-point numbers. In contrast, Digital Signal Processing algorithms are often designed with real numbers in mind and usually implemented in floating-point. Apart from finite wordlength effects that may appear during signal acquisition and intermediate computations, limits on the signal pre...

The Galway Bay wave energy test site promises to be a vital resource for wave energy researchers and developers. As part of the development of this site, a floating power system is being developed to provide power and data acquisition capabilities, including its function as a local grid connection, allowing for the connection of up to three wave energy converter devices. This work shows results...
